Happy Valentine’s Day from Mars to all the readers of Universe Today !
Well it’s truly a solar system wide Valentines celebration. From the Moon, Mars and even Comet Temple 1 with some pixie Stardust for the romantic rendezvous upcoming in a few short hours [Stardust-NExT Flyby at 11:37 p.m. EST Feb 14].
The Martian camera team from Malin Space Systems, San Diego, wishes to share a special heart-shaped feature from Arabia Terra – images above and below – with all Mars fans on this St. Valentine’s Day, Feb. 14, 2011. And certainly, I love Mars ! Especially those gorgeous and brainy twin gals Spirit & Opportunity.

The bright heart shaped feature is about 1 kilometer (0.6 mile) long. Arabia Terra lies in the northern hemisphere of Mars
The tip of the heart lies above a small impact crater centered at 21.9 degrees north latitude, 12.7 degrees west longitude.
According to a JPL press release, “The crater is responsible for the formation of the bright, heart-shaped feature. When the impact occurred, darker material on the surface was blown away, and brighter material beneath it was revealed.

Update: See below the latest navigation camera images taken on Feb. 11 – newly obtained from JPL. These images are crucial for precisely aiming Stardust-NExT
And soon the whole world can watch the up close meet up of the hot Stardust probe and the volatile, icy comet. The historic space tryst is less than a day away!
The Stardust-NExT spacecraft successfully hot fired its thrusters for the final course correction maneuver (TCM-33) on Feb. 12, setting up the fleeting celestial encounter with Comet Tempel 1 on Valentine’s Day, Feb. 14, Monday, at 11:37 p.m. EST. The space science probe will fly by the speeding comet at a distance of approximately 200 kilometers (124 miles) and at a speed of 10 km/sec.
The encounter phase has begun now (Feb. 13) at 24 hours prior to closest approach (Feb. 14) and concludes 24 hours after closest approach.
“The final TCM burn on Feb. 12 went well,” JPL spokesman DC Agle told me today (Feb.13)
It’s been a long wait and a far flung journey. Stardust has cruised some 6 Billion kilometers through our solar system – looping several times around the sun over a dozen years and is now nearly bereft of fuel.
For three and a half long years, the anticipation has been building since NASA approved the repurposing of the Stardust spacecraft in 2007 and fired the thrusters to alter the probes trajectory to Comet Temple 1 for this bonus extended mission.
But until the photos are transmitted across 300 million kilometers of space back to Earth, we won’t know which face of the comets surface was turned towards the camera as the curtain pulls back for the revealing glimpse.
Everything hinges on how accurately the mission team aims the reliable probe and the finicky rotation of the changeable comet.
The irregularly shaped nucleus of Tempel 1 measures barely 5 to 8 km in diameter. Stardust-NExT: 2 Comet Flybys with 1 Spacecraft.
Stardust-NExT makes history on Valentine’s Day - February, 14, 2011
Tempel 1 is the first comet to be visited twice by spacecraft from Earth. Stardust will have visited 2 comets and gathered science data: Comet Wild 2 in 2004 (left) and Comet Tempel 1 in 2011 (right).

The Feb. 14 encounter marks the first time in history that a comet has been visited twice by spaceships from Earth. The revisit provides the first opportunity for up-close observations of a comet both before and after a single orbital pass around the sun.
In July 2005, NASA’s Deep Impact probe delivered a 375 kg projectile that penetrated at high speed directly into the comets nucleus. The blast created an impact crater and ejected an enormous cloud of debris that was studied by the Deep Impact spacecraft as well as an armada of orbiting and ground based telescopes.
Somewhat unexpectedly, the new crater was totally obscured from the cameras view by light reflecting off the dust cloud.
“The primary goal is to find out how much the comet’s surface has changed between two close passages to the sun since it was last visited in 2005,” says Joe Ververka of Cornell University, who is the principal investigator of the Stardust-NExT mission.
This time around, researchers hope to determine the size of the crater. Numerous bets hinge on that determination.
It’s also quite possible that the crater itself has significantly changed in the intervening five and one half years as the Jupiter-class comet orbits between Mars and Jupiter.
“Comets rarely behave,” says Tim Larson, the Stardust-NExT mission project manager from the Jet Propulsion Laboratory (JPL), Pasadena, Calif.
“Temple 1 exhibits a complex rotation. The rotation period is about 41 hours. But the trajectory changes due to the comet jets and activity.”
“Ideally we would like to obtain photos of old and new territory and the crater from the Deep Impact encounter in 2005,” Larson explained.
“Tempel 1 is the most observed comet in history using telescopes worldwide as well as the Hubble and Spitzer Space Telescopes.”
Engineers are using all this data to fine tune the aim of the craft and get a handle on which sides of the comet will be imaged. But either way the team will be elated with the science results regardless of whether the images reveal previously seen or new terrain.

Today, Feb. 13, mission controllers at JPL are uplinking the final flyby sequences and parameters for Monday’s (Feb. 14) historic encounter.
Stardust-NExT will take 72 high resolution images of Comet Tempel 1 during the close approach. The team expects the nucleus to be resolved in several of the closest images. These will be stored in an onboard computer and relayed back to Earth starting about three hours later.
“All data from the flyby (including the images and science data obtained by the spacecraft’s two onboard dust experiments) are expected to take about 10 hours to reach the ground,” according to a NASA statement.

Stardust was originally launched way back in 1999 and accomplished its original goal of flying through a dust cloud surrounding the nucleus of Comet Wild 2 on Jan. 2, 2004. During the flyby, the probe also collected comet particles which were successfully returned to Earth aboard a sample return capsule which landed in the Utah desert in January 2006.
Stardust continued its solitary voyage through the void of the space. Until now !

Five facts you should know about NASA’s Stardust-NExT spacecraft as it prepares for a Valentine’s “date” with comet Tempel 1. From a NASA Press Release
1. “The Way You Look Tonight” – The spacecraft is on a course to fly by comet Tempel 1 on Feb. 14 at about 8:37 p.m. PST (11:37 p.m. EST) — Valentine’s Day. Time of closest approach to Tempel 1 is significant because of the comet’s rotation. We won’t know until images are returned which face the comet has shown to the camera.

Credit: NASA/JPL2. “It’s All Coming Back To Me Now” – In 2004, Stardust became the first mission to collect particles directly from a comet, Wild 2, as well as samples of interstellar dust. The samples were returned in 2006 via a capsule that detached from the spacecraft and parachuted to the ground at a targeted area in Utah. Mission controllers then placed the still-viable Stardust spacecraft on a flight path that could reuse the flight system, if a target of opportunity presented itself. Tempel 1 became that target of opportunity.
3. “The First Time Ever I Saw Your Face” – The Stardust-NExT mission will allow scientists for the first time to look for changes on a comet’s surface that occurred after one orbit around the sun. Tempel 1 was observed in 2005 by NASA’s Deep Impact mission, which put an impactor on a collision course with the comet. Stardust-NExT might get a glimpse of the crater left behind, but if not, the comet would provide scientists with previously unseen areas for study. In addition, the Stardust-NExT encounter might reveal changes to Tempel 1 between Deep Impact and Stardust-Next, since the comet has completed an orbit around the sun.
4. “The Wind Beneath My Wings” – This Tempel 1 flyby will write the final chapter of the spacecraft’s success story. The aging spacecraft approached 12 years of space travel on Feb. 7, logging almost 6 billion kilometers (3.5 billion miles) since launch. The spacecraft is nearly out of fuel. The Tempel 1 flyby and return of images are expected to consume the remaining fuel.
5. “Love is Now the Stardust of Yesterday” – Although the spacecraft itself will no longer be active after the flyby, the data collected by the Stardust-NExT mission will provide comet scientists with years of data to study how comets formed and evolved.
Do you know the artists names who wrote and sing these celestially romantic tunes ?

The Lockheed Martin Orion team at NASA’s Michoud Assembly Facility in New Orleans, La., inspects the first Orion crew module known as the Ground Test Article (GTA) prior to shipping to Lockheed Martin’s Denver facilities. In Denver, the GTA will be integrated with an encapsulating aeroshell to provide thermal protection before undergoing rigorous testing to verify it can withstand the harsh environments of a deep space mission. The aeroshell will complete the exterior of the spacecraft, as depicted in the hanging banner displayed in the upper left. Credit: NASA
The Orion crew cabin – know as the Ground Test Article or GTA – was shipped by truck and will arrive in Denver on Feb. 14 according to a Lockheed Martin spokesperson.
The next step at Denver is to install the heat shield and thermal protection backshell. The pathfinding vehicle will then be subjected to performance testing inside the acoustic and environmental testing chamber. The testing exercise ensures the vehicle can meet the challenges of ascent, on-orbit operations and safe landing.
“This is a significant milestone for the Orion project and puts us on the right path toward achieving the President’s objective of Orion’s first crewed mission by 2016,” said Cleon Lacefield, Lockheed Martin vice president and Orion program manager. “Orion’s upcoming performance tests will demonstrate how the spacecraft meets the challenges of deep-space mission environments such as ascent, launch abort, on-orbit operations, high-speed return trajectory, parachute deployment, and water landings in a variety of sea states.”
Engineers for Lockheed Martin successfully finished the initial construction and testing phase for this prototype Orion crew cabin at New Orleans. The final pieces of the Orion GTA were welded together in late May 2010 using a state of the art friction stir welding process. See photos below from my inspection tour of the newly welded Orion GTA.
The spacecraft underwent proof pressure testing this past fall. Several mass and volume simulators including the parachutes were installed by the technical team to ready the capsule for shipment.

In Denver, the vehicle will be bombarded with acoustic energy and vibrations to simulate flight like situations that correlate the structural environment inside and outside the vehicle. The tests will determine if the spacecraft was properly designed to survive the harsh rigors of spaceflight. Lessons learned will be incorporated into the tools and manufacturing processes that will eventually lead to a human rated production vehicle.
The GTA vehicle will then be transported to NASA’s Langley Research facility for drop tests to simulate, validate and certify a variety of water landing scenarios at the new Hydro Impact Basin. The Langley facility will be used to test and certify water landing for all human-rated spacecraft for NASA according to Lockheed.
NASA and Lockheed hope to launch the first unmanned Orion test flight in 2013 if the budget allows. Construction of the service module and other key components is in progress.
Orion has achieved other significant development milestones in the past year.

The emergency abort rocket was successfully tested on May 6, 2010 at the U.S. Army’s White Sands Missile Range near Las Cruces, N.M. The abort rocket is bolted atop the crew cabin and is designed to pull the capsule away from the launcher in a split second in an emergency and save astronauts lives.
“The Phase 1 Safety Review was completed in June 2010 and formally acknowledges that Orion’s design meets all of NASA’s critical safety requirements for a human-rated space flight vehicle for flights to low earth orbit (LEO), lunar and deep space missions,” according to Larry Price, Orion Deputy Program Manager at Lockheed Martin.
In the past year the Orion budget has been cut significantly by NASA due to lack of funding from the federal government and the outlook for future funding is uncertain. The new Congress is aiming to cut NASA’s research and development budget even further.

Lockheed Martin Space Systems Company is the prime contractor for Orion and designed and built the GTA as part of a multiyear contract awarded by NASA worth some $3.9 Billion US Dollars. The goal is to produce a new, US-built manned capsule capable of launching American astronauts into space in the post shuttle era.
As soon as the shuttles are retired – for lack of money – the United States will have no capability to loft American astronauts to the International Space Station (ISS) for at least several years. NASA – and all other ISS partners – will be wholly dependent on the Russian Soyuz capsules for launching astronauts to the ISS until either the Orion or commercially developed space taxis such as the Dragon spacecraft from SpaceX are ready for flight. The first operational unmanned Dragon was test flown in Dec 2010.
The Obama Administration sought to cancel Orion in Feb. 2010 as part of NASA’s Project Constellation Return to the Moon program, but then decided to continue Orion’s development after the cancellation proposal met strong bipartisan opposition in Congress.
Orion was to have been launched atop the Ares 1 rocket which has now been officially cancelled. NASA has started the design of a replacement for the Ares 1 which will most likely be a shuttle derived vehicle. Congress has mandated that the first test flight of the still undefined heavy lift rocket must take place by 2016.
Alternatively, Orion could be launched atop a Delta 4 Heavy booster after the rocket is man-rated.

She is the youngest orbiter in NASA’s fleet – and she is being looked at to keep her country in space during a period when the U.S. will lack the capability to do so. Both Endeavour and her sister Atlantis are part of a proposal to keep the shuttles flying into 2017. United Space Alliance (USA) submitted the proposal in the latter part of 2010 as part of NASA’s Commercial Crew Development Round 2 ( CCDev2).
NASA asked aerospace firms for concepts and ideas to advance the cause of commercial crew transportation. NASA has offered to provide funding to companies to look into various manned space flight systems. USA submitted the Commercial Space Transportation System (CSTS) – an adapted version of the shuttle’s Space Transportation System title.
USA wanted to make sure that all options for crew transportation to orbit were on the table. That included keeping the orbiters Atlantis and Endeavour in service until 2017. If this plan succeeds, the shuttles could conduct missions as quickly as by the year 2013. They would have to wait for new external tanks to be produced. Two flights annually would cost approximately $1.5 billion.
Although some are calling the proposal a “long shot” the plan has some very tangible merits. It would limit the “gap” between the end of the end of the shuttle era and when commercial space-taxis could begin ferrying astronauts to the International Space Station (ISS). Keeping the shuttles in service would also help to significantly decrease dependence on the Russian Soyuz for access to the orbiting outpost.
“The CSTS could provide a near-term U.S. solution for crew transport until a new system is ready. It could provide a low-risk approach to bridging the gap in human spaceflight since the program has been flying since 1981 and is well understood,” USA spokesperson Tracy Yates told Universe Today. “It could also provide redundancy for human access to the ISS and therefore ensure the continued viability of an important national asset. The concept has the potential to offer a proven vehicle operated by a seasoned workforce at a market-driven price. It preserves down-mass capability, stabilizes a larger portion of the human spaceflight workforce for future NASA programs and keeps more crew transport dollars at home.”
For the Space Coast this proposal would also have the added benefit of staving off the crippling unemployment that has come as part of the one-two punch of the end of the shuttle era and the cancellation of the Constellation Program.
Although the CSTS has a specific date (2017) mentioned – it is capable of remaining in effect until the new commercial systems come online. This proposal would allow NASA to utilize a proven space vehicle and the overall idea of a “commercial shuttle program” is actually nothing new – the idea has been bandied about since the 90s.
However, while the cost is less than the $3 billion the shuttle program cost in 2010, it is basically the same amount that NASA is paying Space Exploration Technologies (SpaceX) for 12 missions to the space station. The NewSpace firm has stated that four manned flights would cost approximately $550 million.
Space Exploration Technologies (SpaceX) has stated that a flight on the manned version of the Dragon spacecraft would cost about $140 million. Image Credit: SpaceX
“The main thing that this program has going against it is this, what does the shuttle offer that the HTV, ATV, Soyuz and soon commercial craft can’t offer,” said noted space historian David M. Harland. “In today’s economic climate it makes more sense to pay $50 million or so for a seat on Soyuz.”

What do NASA, Robots, the Sun and the NFL have in common ?
Well … its Super SUNday … for Super Bowl XLV on Feb. 6, 2011
The unlikely pairing of Football and Science face off head to head on Super Bowl SUNday. Millions of television viewers will see NASA’s Robonaut 2, or R2, share the the limelight with the Steelers and the Packers of the NFL. The twin brother of R2 is destined for the International Space Station (ISS) and will become the first humanoid robot in space. It will work side by side as an astronaut’s assistant aboard the space station.
The fearsome looking R2 is set to make a first ever special guest appearance during the FOX Networks Super Bowl pre-game show with FOX sports analyst Howie Long. The pre-game show will air starting at 2 p.m. EST on Feb. 6.
And there’s more.
The Sun from Stereo B. Credit: NASA On Super SUNday Feb. 6, NASA will publish Humankinds first ever image of the ‘Entire Sun’ courtesy of NASA’s twin STEREO spacecraft. And given the stunningly cold and snowy weather in Dallas, the arrival of our Sun can’t come soon enough for the ice covered stadium and football fans. See photos above and below.
The two STEREO spacecraft will reach positions on opposite sides of the Sun on Sunday, Feb. 6 at about 7:30 p.m. in the evening, possibly coinciding with the Super Bowl half time show.
At opposition, the STEREO duo will observe the entire 360 degrees sphere of the Sun’s surface and atmosphere for the first time in the history of humankind.
The nearly identical twin brother of R2 is packed aboard Space Shuttle Discovery and awaiting an out of this world adventure from Launch Pad 39 A at NASA’s Kennedy Space Center (KSC) in Florida. Blast off of the first humanoid robot is currently slated for Feb. 24.
R2 is the most dextrously advanced humanoid robot in the world and the culmination of five decades of wide-ranging robotics research at NASA and General Motors (GM).
This newest generation of Robonauts are an engineering marvel and can accomplish real work with exceptionally dexterous hands and an opposable thumb. R2 will contribute to the assembly, maintenance and scientific output of the ISS
“R2 is the most sophisticated robot in the world,” says Rob Ambrose, Chief of NASA’s Johnson Space Center’s (JSC) Robotics Division.
“We hope R2 should help to motivate kids to study science and space,” Ron Diftler told me in an interview at KSC. Diftler is NASA’s R2 project manager at JSC.

The amazingly dexterity of the jointed arms and hands enables R2 to use exactly the same tools as the astronauts and thereby eliminates the need for constructing specialized tools for the robots –saving valuable time, money and weight.
The robot is loaded with advanced technology including an optimized overlapping dual arm dexterous workspace, series elastic joint technology, extended finger and thumb travel, miniaturized 6-axis load cells, redundant force sensing, ultra-high speed joint controllers, extreme neck travel, and high resolution camera and IR systems.
R2 weighs some 300 pounds and was manufactured from nickel-plated carbon fiber and aluminum. It is equipped with two human like arms and two hands as well as four visible light cameras that provide stereo vision with twice the resolution of high definition TV.
“With R2 we will demonstrate ground breaking and innovative robotics technology which is beyond anything else out there and that will also have real world applications as GM works to build better, smarter and safer cars,” according to Susan Smyth, GM Director of Research and Development.
“Crash avoidance technology with advanced sensors is a prime example of robonaut technology that will be integrated into GM vehicles and manufacturing processes.”
A team of engineers and scientists from NASA and GM pooled resources in a joint endeavor to create Robonaut 2, the most dexterously advanced robot in history. The NASA/GM team is pictured here at the Kennedy Space Center. R2 will fly aboard Space Shuttle Discovery with the STS-133 crew of humans and become the first humanoid robot in space.

I was fortunate to meet R2 and the Robonaut team at KSC. R2 is incredibly life like and imposing and I’ll never forget the chance to shake hands. Although its motions, sounds, illuminated hands and muscular chest gives the unmistakable impression of standing next to a lively and powerful 300 pound gorilla, it firmly but gently grasped my hand in friendship – unlike a Terminator.
So its going to make for a mighty match up some day between the fearsome looking R2 and the NFL players.
Well apparently, R2 and Howie will be making some predictions on which player will win the MVP award and a GM Chevrolet. Stay tuned.
So come back on SUNday Feb. 6 for NASA’s release of the first ever images of our entire Sun from the STEREO twins.

With the startling new finding of dozens of Earth-sized extrasolar planets, NASA’s Kepler planet hunting space telescope has just revolutionized our understanding of Earths place in the Universe and the search for Extraterrestrial Life. And the historic science discovery is based on data collected in just the first few months of operation of the powerful telescope as it scans only a tiny portion of the sky.
The discovery of 1235 new extrasolar planet candidates was announced today (Feb.2) by NASA and Kepler scientists at a media briefing. 68 of these planet candidates are Earth-sized. Another 288 are Super-Earth-size, 662 are Neptune-size and 165 are Jupiter-size. Most of these candidates orbit stars like our sun.
Even more significant is that 54 of the planet candidates are located within the ‘habitable zone’ of their host stars and 5 of those are Earth-sized. Before today we knew of exactly ZERO Earth-sized planets within the habitable zone. Now there are 5.
Finding a ‘Pale Blue Dot’ or ‘Second Earth’ inside a habitable zone that harbors water and environmental conditions that can support life is the ‘Holy Grail’ of science.
Are We Alone ?
“We went from zero to 68 Earth-sized planet candidates and zero to 54 candidates in the habitable zone – a region where liquid water could exist on a planet’s surface. Some candidates could even have moons with liquid water,” said William Borucki of NASA’s Ames Research Center, Moffett Field, Calif.. Borucki is the science principal investigator for NASA’s Kepler mission.
“Five of the planetary candidates are both near Earth-size and orbit in the habitable zone of their parent stars.”
Earth-sized water worlds are the most conducive to the formation and evolution of alien life forms. Water is an essential prerequisite for life as we know it.
“Kepler’s blown the lid off everything we know about extrasolar planets,” said Debra Fischer, professor of Astronomy at Yale University, New Haven, Conn

Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zones around their parent stars. The mission uses the transit method to detect the tell tale signatures of planets. The goal is to determine how common are planets the size of Earth orbiting inside the habitable zone of stars like our sun.
Kepler measures the miniscule decreases in the brightness of stars caused by planets crossing in front of them and blocking the starlight. Imagine calculating the difference in light transmission caused by a flea sitting on a cars headlight.
Follow up observations over a period of several years will be required to confirm these results, the scientists explained. Astronomers expect that over 80% of the candidate planets will be positively confirmed as real planets by utilizing ground based observatories and the Spitzer Space Telescope.
For an Earth-sized planet orbiting a sun-like star inside the habitable zone, transits occur about once per year. Since three transits are required to verify a planets status, it will therefore take about three years to reach a definitive conclusion.
These remarkable new planet discoveries are based on observations from only the first four months of Kepler’s telescopic operations – May 12, 2009 to Sept. 17, 2009. The space based observatory continuously monitors more than 156,000 stars using 42 CCD detectors with a field of view that covers only 1/400 of the sky.
“Kepler is making good progress towards its goals,” said Borucki
“We have found over twelve hundred candidate planets – that’s more than all the people have found so far in history.”
“Imagine if we could look wider. Kepler looks at one 400th of the sky. If we had 400 of these fields of view, we’d see 400 times that number of candidates. We would see 400,000 candidate planets.”
Keplers over 1200 Planet candidates sorted by size
“The fact that we’ve found so many planet candidates in such a tiny fraction of the sky suggests there are countless planets orbiting stars like our sun in our galaxy,” Borucki amplified. “Our results indicate there must be millions of planets orbiting the stars that surround our sun.”
“If we find that Earth’s are common in the habitable zones of stars, very likely that means life is common around these stars.”
“Kepler has shown that planetary systems like our own are common,” said Debra Fischer.

Before and after the discovery of over 1200 planet candidates by NASA’s Kepler Space Telescope.
“The search for planets is motivated by the search for life,” Fischer added.
“We have allowed the public to participate though the website Planethunters.org,” she added. “And now we have over 16,000 dedicated users. The public is excited to be a part of research and history.”
“Thanks to Kepler for this treasure chest of data!” Fisher concluded.
Kepler is just the first step in finding Earth sized and Earth like planets. “We are building the foundation for future generations of explorers,” said Borucki.
“Future missions will be developed to study the composition of planetary atmospheres to determine if they are compatible with the presence of life. The design for these missions depends on Kepler finding whether Earth-size planets in the habitable zone are common or rare.”
The first planets beyond our solar system were discovered in 1995. Up to today there were just over 500 known extrasolar planets.
Kepler now has 15 confirmed extrasolar planet discoveries and over 1200 possible candidates.
NASA’s Kepler spacecraft was launched on March 6, 2009 from Launch Complex 17-B atop a Delta II rocket at Cape Canaveral Air Force Station in Florida. See spacecraft and launch photos below
Kepler’s science operations are currently funded for three and one half years of operations until November 2012. The mission’s lifetime – and its goal of discovering multitudes of new planets as small as Earth – can be extended if NASA funding is approved by Congress and the President.

Video Caption: NASA’s Kepler mission has discovered its first Earth-size planet candidates and its first candidates in the habitable zone, a region where liquid water could exist on a planet’s surface. Five of the potential planets are near Earth-size and orbit in the habitable zone of smaller, cooler stars than our sun.
Kepler also found six confirmed planets orbiting a sun-like star, Kepler-11. This is the largest group of transiting planets orbiting a single star yet discovered outside our solar system. Located approximately 2,000 light years from Earth, Kepler-11 is the most tightly packed planetary system yet discovered. All six of its confirmed planets have orbits smaller than Venus, and five of the six have orbits smaller than Mercury’s.

Forty years ago today, the Apollo 14 crew launched on their Saturn V rocket, the 6th human flight to the Moon and the third that landed. Following the heart-stopping problems of Apollo 13, almost ten months elapsed before Commander Alan Shepard (the first American in space), Command Module Pilot Stuart Roosa, and Lunar Module Pilot Edgar Mitchell set off on January 31, 1971. They reached the Moon on February 5, and Shepard and Mitchell walked the Fra Mauro highlands, originally been the target of the aborted Apollo 13 mission. The two astronauts had to scrap a planned rock-collecting trip to the 1,000 foot wide Cone Crater when they became disoriented and almost got lost. Interestingly, recent images from the Lunar Reconnaissance Orbiter revealed they were only a little over 30 yards from the crater’s rim when they gave up the search. But they did have many successes as well.
Also on this date 50 years ago was the flight that made Alan Shepard’s suborbital Mercury flight possible: the Mercury-Redstone 2 (MR-2) mission carrying Ham, a four-year-old male chimpanzee. The suborbital flight lasted a total of 16 minutes and 39 seconds, and carried the spacecraft 422 nautical miles from the launch site at Cape Canaveral, FL, reaching a maximum altitude of 157 statute miles. The flight reached all its objectives, paving the way for human flights.
On Super Bowl SUNday - Feb 6, 2011; the two NASA STEREO spacecraft willl see the entire Sun ! Superbowl SUNday will truly mark a milestone for solar observations. On Ferbruary 6, the two STEREO spacecrafts will be 180 degrees apart and for the next 8 years the STEREO spacecrafts and SDO will be able to observe the entire 360 degrees of the Sun. Credit: NASA. Watch the cool STEREO Whole Sun Preview Video below. Plus Launch Video and more photos below.
“For the first time in the history of humankind we will be able to see the front and the far side of the Sun … Simultaneously,” Madhulika Guhathakurta told Universe Today. Guhathakurta is the STEREO Program Scientist at NASA HQ.
And the noteworthy event is timed to coincide just perfectly with ‘Super Bowl SUNday’ – Exactly one week from today on Feb. 6 during Super Bowl XLV !
“This will be the first time we can see the entire Sun at one time,” said Dean Pesnell, NASA Solar Astrophysicist in an interview for Universe Today. Pesnell is the Project Scientist for NASA’s Solar Dynamics Observatory at the NASA Goddard Spaceflight Center in Greenbelt, MD.
This remarkable milestone will be achieved when NASA’s two STEREO spacecraft reach position 180 degrees separate on opposite sides of the Sun on Sunday, Feb. 6, 2011 and can observe the entire 360 degrees of the Sun.
“We are going to celebrate by having a football game that night!” Pesnell added in jest.
The nearly identical STEREO spacecraft – dubbed STEREO Ahead and STEREO Behind – are orbiting the sun and providing a more complete picture of the Suns environment with each passing day. One probe follows Earth around the sun; the other one leads the Earth.
STEREO is the acronym for Solar TErrestrial RElations Observatory. Their mission is to provide the very first, 3-D “stereo” images of the sun to study the nature of coronal mass ejections.
Today, (Jan 30) the twin STEREO spacecraft are 179.1 degrees apart and about 90 degrees from Earth, and thus virtually at the midpoint to the back of the sun. See the orbital location graphics above and below.
Both probes were flung into space some four years ago and have been hurtling towards this history making date and location ever since. The wedge of unseen solar territory has been declining.
As the STEREO probes continue flying around to the back side of the sun, the wedge of unseen solar territory on the near side will be increasing and the SDO solar probe will play a vital gap filling role.
“SDO provides the front side view of the sun with exquisite details and very fast time resolution,” Gutharka told me. For the next 8 years, when combined with SDO data, the full solar sphere will still be visible.
The Whole Sun will be simultaneously Imaged for the First tIme ever on Super Bowl SUNday Feb. 6.
For the past 4 years, the two STEREO spacecraft have been moving away from the Earth and gaining a more complete picture of the sun. On February 9, 2011, NASA will hold a press conference to reveal the first ever images of the entire sun and discuss the importance of seeing all of our dynamic star.

The solar probes were launched together aboard a Delta II rocket from Launch Complex 17B at Cape Canaveral Air Force Station (CCAFS) in Florida on October 25, 2006. See Launch Video and Photos below.
Whole Solar Sphere A Goldmine for Science
I asked Pesnell and Guhathakurta to explain why this first ever whole Sun view is a significant scientific milestone.
“Until now there has always been an unseen part of the Sun,” Pesnell explained. “Although that unseen part has always rotated into view within a week or two, a global model must include all of the Sun to understand where the magnetic field goes through the surface.”
“Also, from the Earth we can see only one pole of the Sun at a time, while with STEREO we can see both poles at the same time.
“The next few years of overlapping coronal images will be a goldmine of information for predicting space weather at the Earth and understanding of how the Sun works. It is like getting the GOES images of the Earth for the first time. We haven’t missed a hurricane since, and now we won’t miss an active region on the Sun,” said Pesnell.
How will the science data collected be used to understand the sun and its magnetic field?
“Coronal loops trace out the magnetic field in the corona,” Pesnell elaborated. “Understanding how that magnetic field changes requires seeing where on the surface each loop starts and stops.”
Why is it important to image the entire Sun ?
“Once images of the entire Sun are available we can model the entire magnetic field of the Sun. This has become quite important as we are using STEREO and SDO to study how the entire magnetic field of the Sun reacts to the explosions of even small flares.”
“By seeing both poles we should be able to understand why the polar magnetic field is a good predictor of solar activity,” said Pesnell.
“Seeing both sides will help scientists make more accurate maps of global coronal magnetic field and topology as well as better forecasting of active regions – areas that produce solar storms – as they rotate on to the front side. Simultaneous observations with STEREO and SDO will help us study the sun as a complete whole and greatly help in studying the magnetic connectivity on the sun and sympathetic flares, ” Guhathakurta amplified.

What is the role and contribution of NASA’s SDO mission and how will SDO observations be coordinated with STEREO?
“As the STEREO spacecraft drift around the Sun, SDO will fill in the gap on the near of the Sun,” explained Pesnell. “For the next 4 or more years we will watch the increase in sunspots we call Solar Cycle 24 from all sides of the Sun. SDO has made sure we are not doing calibration maneuvers for a few days around February 6.”
“On Feb 6th we will view 100% of the sun,” said Guhathakurta.
At a press conference on Feb. 9, 2011, NASA scientists will reveal something that no one has even seen – The first ever images of ‘The Entire Sun’. All 360 degrees

Japans critical new resupply spaceship – nicknamed Kounotori2, (HTV2) – was successfully berthed today (Jan. 27) at the International Space Station (ISS). Kounotori2 – which translates as ‘White Stork’ in Japanese – was grappled by the ISS crew and then manually nested to an Earth facing docking port on the Harmony module.
Kounotori2 was launched aboard a Japanese H-IIB rocket from the Tanegashima Space Center in southern Japan at 12:37 a.m. (2:27 p.m. Japan time) on Jan. 22 to begin a five day orbital chase of the station.
View the Video and a Photo album below of the rendezvous and docking sequence
The two ships became one as Astronaut Cady Coleman grappled the free flying ‘White Stork’ at 6:41 a.m. EST with the stations robotic arm while the vessels were flying in formation about 220 miles above the south Indian Ocean in an easterly direction.
“Grapple completed, Kounotori is grappled!”

After an automatic rendezvous early this morning, the unmanned HTV2 cargo carrier slowly approached the space station from below to a series of ever closer hold points- 250 m, 30 m and 10 m.
Mission controllers on Earth carefully maneuvered the 35,000 pound ship to the final capture distance of about 33 feet (10 meters). The HTV thrusters were disabled and it was placed into ‘free drift’ mode.
ISS astronauts Paolo Nespoli, Cady Coleman and Commander Mark Kelly crew monitored the approach from inside the ISS. The crew was deftly working at the controls of the robotics work station of the Cupola Observation dome.

Finally, Coleman gently grabbed the ‘White Stork’ with the 58 foot long Space Station Robotic arm, built and contributed by Canada.
“Grapple completed, Kounotori is grappled!” tweeted and twitpiced Paolo Nespoli from the ISS.
“This demonstrates what we can do when humans and robots work together,” radioed Cady Coleman.”We look forward to bringing HTV 2 – Kounotori – aboard the International Space Station.”

From: NASAtelevision | January 27, 2011 An unpiloted Japanese resupply ship, the “Kounotori”2 H-2B Transfer Vehicle (HTV2 ), was captured and berthed to the Earth-facing port of the Harmony module of the International Space Station Jan. 27, 2011. The berthing took place after an automated five-day flight following its launch on the Japan Aerospace Exploration Agency’s H-2B rocket Jan. 22 from the Tanegashima Space Center in southern Japan. The ‘Kounotori’, which means “white stork” in Japanese, is loaded with more than four tons of supplies and spare parts for the six crew members on the orbital laboratory. Expedition 26 Flight Engineers Cady Coleman and Paolo Nespoli were at the controls of the robotic work station in the space station’s Cupola module to maneuver the Canadarm2 robotic arm for the grapple and berthing of the HTV2, which will remain at the orbital outpost until the end of March
Italian astronaut Paolo Nespoli had the honor of driving Kounotori2 to a hard dock at the station. The attachment was completed at 9:51 a.m. EST after Kelly inspected the docking mechanism and confirmed it was clear of debris and ready. 16 bolts firmly latched the cargo freighter into place a few hours later.
The crew will open the hatch to Kounotori2 on Friday, (Jan. 28) at about 7:30 a.m. This is only the second flight of the Kounotori. The barrel shaped vehicle is coated with 57 solar panels.
HTV-2, we are ready for you! HTV-2, siamo pronti per te! ISS Tweet and Twitpic Credit: NASA/Paolo Nespoli
Kounotori2 is loaded with over 4 tons of pressurized and unpressurized cargo, including science experiments, research gear, space parts, clothing, food and water and other provisions from Japan, NASA and Canada.
HTV2 will remain docked at the ISS for about two months until late March. During that time the ISS crew will retrieve all the equipment and supplies for transfer to locations both inside and outside the ISS.
Using the Canadian robotic arm and Dextre robot, a pallet loaded with large spare parts for the station will be extracted from a slot on the side of the cargo ship robot and attached to an experiment platform outside the Japanese Kibo module.

On Feb. 18, the ISS crew will move the HTV from the Earth facing port. They will relocate it 180 degrees to the other side of the Harmony module to the space facing zenith port. This maneuver is required to provide enough clearance for Space Shuttle Discovery so that the orbiter can also safely dock at the Harmony module in late February. Discovery is set to launch on Feb. 24.
The HTV2 docking marks the start of an extremely busy time of orbital comings and goings at the ISS.
A Russian Progress resupply ship launches later today, at 8:31 p.m. EST. Following a two day chase, the Progress will dock on Saturday night (Jan. 29) at 9:39 p.m. and deliver over 6000 pounds of cargo to the station. Watch NASA TV

How often have you heard (or thought) the sentiment that all NASA really needs is a President who will issue a bold challenge for the space agency, like Kennedy did in 1961, initiating the Apollo program to the Moon? Can we ever expect to witness such a call to action again?
“It is very unlikely,” said space historian and author Andrew Chaikin, who believes Apollo was an historical anomaly. “I think for many decades people saw Apollo as a model for how to do a space program; that you get a President to get up and make a challenge and the country follows along and does great things. But that was only true that one time in the context of the Cold War.”
We went to the Moon when we did not because we were a nation devoted to exploration, Chaikin believes, but because it seemed a politically important course of action in the context of our Cold War with the Soviet Union. “Once that was accomplished, then that political imperative evaporated,” he said.
On May 25, 1961, Kennedy announced his support for the Apollo program as part of a special address to a joint session of Congress:
Likely, we won’t hear any bold space-related challenge in tonight’s State of the Union Address by President Obama. Given the state of the economy, NASA might be facing a cut or freeze on their budget, a fact which might emphasize how unique an event the Apollo program ended up to be.
“What is required now is the development of technologies that will allow us to explore space in a sustainable way,” said Chaikin, author of “A Man on the Moon: The Voyages of the Apollo Astronauts,” who I interviewed for the NASA Lunar Science Institute podcast, “a way that won’t break the bank and will allow us to do more and more with reliable transportation systems that get us up into low Earth orbit. Then perhaps we can build the machines that can actually be stored in space to allow us to venture beyond low Earth orbit to the Moon and even further, to Mars and other destinations in the solar system.”
Chaikin said he’s actually very excited about the work being done in the private sector, such as by SpaceX, one of several commercial space companies trying to develop new transportation systems to provide sustainable hardware and sustainable architecture. “That can allow us to really get back in the game of exploring, not only with robots as we have been doing all along, but with humans again,” Chaikin said.
But Apollo’s uniqueness doesn’t mean it wasn’t important, or hasn’t left a lasting legacy for human spaceflight, and the human race in general.

“Simply put Apollo was the opening act in a story that has no end,” Chaikin said. “It’s a story of human beings leaving their home planet and venturing out into the universe, and as far as we go into space in some distant epoch, when we are living in other star systems and venturing throughout the galaxy, Apollo will have been the first step, so it is absolutely monumental when you look at it in that scale. I think Apollo is a lasting inspiration about what humans can accomplish when they work together.”
Apollo also showed people that anything was possible. “There was a phrase that went into our language after Apollo, and that was ‘If we can put a man on the Moon, why can’t we…’ fill in the blank,” said Chaikin. “The spirit that humans can overcome monumental challenges by working together, I think, is a valid legacy of Apollo culturally.”
Chaikin said Apollo was also important because of the technology development it spurred.
“A lot of the challenges that Apollo presented forced the industries to accelerate their development,” he said, “particularly in microelectronics. It is not that NASA invented all of the microelectronics that we use today but rather that the requirements of building a moon-ship and cramming it with all of the electronics that it needed to do its job required the electronics industry to miniaturize at a faster pace, it required the development of computers that could fit on a spacecraft, it required all kinds of analytical techniques and real-time tracking of the spacecraft as it went to and from the Moon. The legacy today is all the communications technologies and information processing technology that we are surrounded by. That really got an amazing jump start as part of the Apollo program.”
Earthrise from Apollo 8
And Apollo also affected our culture, in unique ways we observe even today. How often have you seen the “Earthrise” image taken by Apollo 8 or the picture of Buzz Aldrin standing on the Moon or other Apollo-related imagery in non-space-related venues?
“We got to a place where humans had never been before,” Chaikin said, “and the other lasting legacy is the view that we got from that ‘mountaintop,’ of our Earth as a very precious oasis of life in space, and a world that really is to be cherished and protected.”
We knew even as it was happening, Chaikin said, that seeing our world floating alone in space was perhaps the most profound impact of the voyage.
“In fact, if you look at the front page of the New York Times the very day after Frank Borman and his crew became the first humans to orbit the Moon,” Chaikin said, “you will see an essay by a poet named Archibald MacLeish talking about the impact of that view and the perspective of us as ‘brothers in the eternal cold riding on spaceship Earth.’ So this is one of the things sets Apollo apart from other earlier explorations is that we were experiencing it as it happened through live television and we were actually absorbing and processing the impact in real time.”
Launch of Apollo 8 lunar orbit mission
But then, humans being as attention-challenged as we are, it didn’t take very long for all of it to become old hat and to kind of recede into history. “And that is where we are today,” Chaikin said.
That being said, Chaikin does not see the Moon as a “been there, done that” world.
“As you know, we’ve been finding frozen water at the poles of the Moon and this is a completely different view of the Moon than we had 40 years ago,” Chaikin said. “And there are more and more intricacies that we are finding all the time. The Moon itself is a Rosetta Stone for deciphering the history of the solar system, and is profoundly valuable world for us on so many levels. And it is a spectacular place. The Apollo astronauts – I’ve spent hours talking to all of them about the Moon, about the experience of being on the Moon and they just say it is a spectacular place.”
“It is too bad that the political impetus for going to the Moon was so short-lived because it was part of the Cold war,” Chaikin continued, “and looking back we can see why that was the case. It is too bad we lost interest in the Moon and it has taken us so long to turn our attention back to the Moon and all it has to offer.”
Listen to the entire interview with Chaikin on the NLSI podcast, which can also be heard on the 365 Days of Astronomy podcast.
