Psst! Live in South Africa and read Universe Today? Then you might just get a peak at the Juno spacecraft as it receives a boost from our fair planet on the evening of October 9th, 2013.
Launched from Cape Canaveral Air Force Station on August 5th, 2011 atop an Atlas 5 rocket in a 551 configuration, Jupiter-bound Juno is approaching the Earth from interior to its orbit over the next month. Its closest approach to the Earth during its October 9th flyby will occur at 19:21 Universal Time (UT) which is 3:21 PM Eastern Daylight Saving Time. The spacecraft will pass 559 kilometres over the South Atlantic to a point 200 kilometres off of the southeastern coast of South Africa at latitude -34.2° south & longitude 34° east.
For context, this is just about 25% higher than the International Space Station orbits at an average of 415 kilometres above the Earth. The ISS is 108.5 metres across on its longest dimension, and we wouldn’t be surprised if Juno were a naked eye object for well placed observers watching from a dark sky site around Cape Town, South Africa. Especially if one of its three enormous 8.9 metre long solar panels were to catch the Sun and flare Iridium-style!
Two minutes before closest approach, Juno will experience the only eclipse of its mission, passing into the umbra of Earth’s shadow for about 20 minutes. Chris Peat at Heavens-Above also told Universe Today that observers in India are also well-placed to catch sight of Juno with binoculars after it exits the Earth’s shadow.
Juno passed its half-way mark to Jupiter last month on August 12th when the “odometer clicked over” to 9.464 astronomical units. Juno will enter orbit around Jupiter on July 4th, 2016. Juno will be the second spacecraft after Galileo to permanently orbit the largest planet in our solar system.
Catching a flyby of Juno will be a unique event. Unfortunately, the bulk of the world will miss out, although you can always vicariously fly along with Juno with Eyes on the Solar System. Juno is currently moving about 7 km/s relative to the Earth, and will move slightly faster than the ISS in its apparent motion across the sky from west to east before hitting Earth’s shadow. This slingshot will give Juno a 70% boost in velocity to just under 12km/s relative to Earth, just slower than Pioneer 10’s current motion relative to the Sun of 12.1km/s.
At that speed, Juno will be back out past the Moon in about 10 hours after flyby. There’s a chance that dedicated imagers based along North American longitudes could still spy Juno later that evening.
Juno approaches the Earth from the direction of the constellation Libra and will recede from us in the direction of the constellation Perseus on the night of October 9th.
There’s also a precedent for spotting such flybys previous. On August 18th, 1999, NASA’s Cassini spacecraft made a flyby of the Earth at 1,171 kilometres distant, witnessed by observers based in the eastern Pacific region. Back then, a fuss had been raised about the dangers that a plutonium-powered spacecraft might posed to the Earth, should a mis-calculation occur. No such worries surround Juno, as it will be the first solar-powered spacecraft to visit the outer solar system.
And NASA wants to hear about your efforts to find and track Juno during its historic 2013 flyby of the Earth. JPL Horizons lists an ephemeris for the Juno spacecraft, which is invaluable for dedicated sky hunters. You can tailor the output for your precise location, then aim a telescope at low power at the predicted right ascension and declination at the proper time, and watch. Precise timing is crucial; I use WWV shortwave radio broadcasting out of Fort Collins, Colorado for ultra-precise time when in the field.
As of this writing, there are no plans to broadcast the passage of Juno live, though I wouldn’t be surprised if someone like Slooh decides to undertake the effort. Also, keep an eye on Heavens-Above, as they may post sighting opportunities as well. We’ll pass ‘em along if they surface!
Late Breaking: And surface they have… a page dedicated to Juno’s flyby of Earth is now up on Heavens-Above.
Juno is slated to perform a one year science mission studying the gravity and magnetic field of Jupiter as well as the polar magnetosphere of the giant planet. During this time, Juno will make 33 orbits of Jupiter to complete its primary science mission. Juno will study the environs of Jupiter from a highly inclined polar orbit, which will unfortunately preclude study of its large moons. Intense radiation is a primary hazard for spacecraft orbiting Jupiter, especially one equipped with solar panels. Juno’s core is shielded by one centimetre thick titanium walls, and it must thread Jupiter’s radiation belts while passing no closer than 4,300 kilometres above the poles on each pass. One run-in with the Io Plasma Torus would do the spacecraft in. Like Galileo, Juno will be purposely deorbited into Jupiter after its primary mission is completed in October 2017.
If you live in the right location, be sure to check out Juno as it visits the Earth, one last time. We’ll keep you posted on any live broadcasts or any further info on sighting opportunities as October 9th draws near!

The next time that American astronauts launch to space from American soil it will surely be aboard one of the new commercially built “space taxis” currently under development by a trio of American aerospace firms – Boeing, SpaceX and Sierra Nevada Corp – enabled by seed money from NASA’s Commercial Crew Program (CCP).
Boeing has moved considerably closer towards regaining America’s lost capability to launch humans to space when the firm’s privately built CST-100 crew capsule achieved two key new milestones on the path to blastoff from Florida’s Space Coast.
The CST-100 capsule is designed to carry a crew of up to 7 astronauts on missions to low-Earth orbit (LEO) and the International Space Station (ISS) around the middle of this decade.
Boeing’s crew transporter will fly to space atop the venerable Atlas V rocket built by United Launch Alliance (ULA) from Launch Complex 41 on Cape Canaveral Air Force Station in Florida.
The Boeing and ULA teams recently completed the first wind tunnel tests of a 7 percent scale model of the integrated capsule and Atlas V rocket (photo above) as well as thrust tests of the modified Centaur upper stage.
The work is being done under the auspices of NASA’s Commercial Crew Integrated Capability (CCiCap) initiative, intended to make commercial human spaceflight services available for both US government and commercial customers, such as the proposed Bigelow Aerospace mini space station.
Since its maiden liftoff in 2002, the ULA Atlas V rocket has flawlessly launched numerous multi-billion dollar NASA planetary science missions like the CuriosityMars rover, Juno Jupiter orbiter and New Horizons mission to Pluto as well as a plethora of top secret Air Force spy satellites.
But the two stage Atlas V has never before been used to launch humans to space – therefore necessitating rigorous testing and upgrades to qualify the entire vehicle and both stages to meet stringent human rating requirements.
“The Centaur has a long and storied past of launching the agency’s most successful spacecraft to other worlds,” said Ed Mango, NASA’s CCP manager at the agency’s Kennedy Space Center in Florida. “Because it has never been used for human spaceflight before, these tests are critical to ensuring a smooth and safe performance for the crew members who will be riding atop the human-rated Atlas V.”
The combined scale model CST-100 capsule and complete Atlas V rocket were evaluated for two months of testing this spring inside an 11- foot diameter transonic wind tunnel at NASA’s Ames Research Center in Moffett Field, Calif.
“The CST-100 and Atlas V, connected with the launch vehicle adaptor, performed exactly as expected and confirmed our expectations of how they will perform together in flight,” said John Mulholland, Boeing vice president and program manager for Commercial Programs.
Testing of the Centaur stage centered on characterizing the flow of liquid oxygen from the oxygen tank through the liquid oxygen-feed duct line into the pair of RL-10 engines where the propellant is mixed with liquid hydrogen and burned to create thrust to propel the CST-100 into orbit.
Boeing is aiming for an initial three day manned orbital test flight of the CST-100 during 2016, says Mulholland.
But that date is dependent on funding from NASA and could easily be delayed by the ongoing sequester which has slashed NASA’s and all Federal budgets.
Chris Ferguson, the commander of the final shuttle flight (STS-135) by Atlantis, is leading Boeing’s flight test effort.
Boeing has leased one of NASA’s Orbiter Processing Facility hangers (OPF-3) at the Kennedy Space Center (KSC) for the manufacturing and assembly of its CST-100 spacecraft.
Mulholland told me previously that Boeing will ‘cut metal’ soon. “Our first piece of flight design hardware will be delivered to KSC and OPF-3 around mid 2013.”
NASA’s CCP program is fostering the development of the CST-100 as well as the SpaceX Dragon and Sierra Nevada Dream Chaser to replace the crew capability of NASA’s space shuttle orbiters.
The Atlas V will also serve as the launcher for the Sierra Nevada Dream Chaser space taxi.
Since the forced retirement of NASA’s shuttle fleet in 2011, US and partner astronauts have been 100% reliant on the Russians to hitch a ride to the ISS aboard the Soyuz capsules – at a price tag exceeding $60 Million per seat.
Simultaneously on a parallel track NASA is developing the Orion crew capsule and SLS heavy lift booster to send humans to the Moon and deep space destinations including Asteroids and Mars.

Triple planets (Venus/Jupiter/Mercury) conjunction over Mont-Saint-Michel, Normandy, France on May 26. Credit: Thierry Legault – www.astrophoto.fr Update: See expanded Conjunction astrophoto gallery below[/caption]
The rare astronomical coincidence of a spectacular triangular triple conjunction of 3 bright planets happening right now is certainly wowing the entire World of Earthlings! That is if our gallery of astrophotos assembled here is any indication.
Right at sunset, our Solar System’s two brightest planets – Venus and Jupiter – as well as the sun’s closest planet Mercury are very closely aligned for about a week in late May 2013 – starting several days ago and continuing throughout this week.
And, for an extra special bonus – did you know that a pair of spacecraft from Earth are orbiting two of those planets?
Have you seen it yet ?
Well you’re are in for a celestial treat. The conjunction is visible to the naked eye – look West to Northwest shortly after sunset. No telescopes or binoculars needed.
Just check out our Universe Today collection of newly snapped astrophoto’s and videos sent to Nancy and Ken by stargazing enthusiasts from across the globe. See an earlier gallery – here.
Throughout May, the trio of wandering planets have been gradually gathering closer and closer.
On May 26 and 27, Venus, Jupiter and Mercury appear just 3 degrees apart as a spectacular triangularly shaped object in the sunset skies – which
adds a palatial pallet of splendid hues not possible at higher elevations.
And don’t dawdle if you want to see this celestial feast. The best times are 30 to 60 minutes after sunset – because thereafter they’ll disappear below the horizon.
The sky show will continue into late May as the planets alignment changes every day.
On May 28, Venus and Jupiter close in to within just 1 degree.
And on May 30 & 31, Venus, Jupiter and Mercury will form an imaginary line in the sky.
Triple planetary conjunctions are a rather rare occurrence. The last one took place in May 2011. And we won’t see another one until October 2015.
Indeed the wandering trio are also currently the three brightest planets visible. Venus is about magnitude minus 4, Jupiter is about minus 2.
While you’re enjoying the fantastic view, ponder this: The three planets are also joined by two orbiting spacecraft from humanity. NASA’s MESSENGER is orbiting Mercury. ESA’s Venus Express is orbiting Venus. And NASA’s Juno spacecraft is on a long looping trajectory to Jupiter.
Send Ken you conjunction photos to post here.

All right, it may look just like any other picture you’ve ever seen of the Big Dipper. Maybe even a little less impressive, in fact. But, unlike any other picture, this one was taken from 290 million km away by NASA’s Juno spacecraft en route to Jupiter, part of a test of its Junocam instrument! Now that’s something new concerning a very old lineup of stars!
“I can recall as a kid making an imaginary line from the two stars that make up the right side of the Big Dipper’s bowl and extending it upward to find the North Star,” said Scott Bolton, principal investigator of NASA’s Juno mission. “Now, the Big Dipper is helping me make sure the camera aboard Juno is ready to do its job.”
The image is a section of a larger series of scans acquired by Junocam between 20:23 and 20:56 UTC (3:13 to 3:16 PM EST) on March 14, 2012. Still nowhere near Jupiter, the purpose of the imaging exercise was to make sure that Junocam doesn’t create any electromagnetic interference that could disrupt Juno’s other science instruments.
In addition, it allowed the Junocam team at Malin Space Science Systems in San Diego, CA to test the instrument’s Time-Delay Integration (TDI) mode, which allows image stabilization while the spacecraft is in motion.
Because Juno is rotating at about 1 RPM, TDI is crucial to obtaining focused images. The images that make up the full-size series of scans were taken with an exposure time of 0.5 seconds, and yet the stars (brightened above by the imaging team) are still reasonably sharp… which is exactly what the Junocam team was hoping for.
“An amateur astrophotographer wouldn’t be very impressed by these images, but they show that Junocam is correctly aligned and working just as we expected”, said Mike Caplinger, Junocam systems engineer.
As well as the Big Dipper, Junocam also captured other stars and asterisms, such as Vega, Canopus, Regulus and the “False Cross”. (Portions of the imaging swaths were also washed out by sunlight but this was anticipated by the team.)
These images will be used to further calibrate Junocam for operation in the low-light environment around Jupiter, once Juno arrives in July 2016.
Read more about the Junocam test on the MSSS news page here.
As of May 10, Juno was approximately 251 million miles (404 million kilometers) from Earth. Juno has now traveled 380 million miles (612 million kilometers) since its launch on August 5, 2011 and is currently traveling at a velocity of 38,300 miles (61,600 kilometers) per hour relative to the Sun.
Launched on August 5, 2011, NASA’s Juno spacecraft will arrive at Jupiter in 2016 to study its magnetic field and atmosphere. Using its suite of science instruments Juno will peer inside the gas giant’s thick clouds, revealing hidden structures and powerful storms. To help people visualize what it means to see the invisible, JPL’s visual strategist Dan Goods created the exhibit above, titled Beneath the Surface. It’s an installation of lights, sound and fog effects that dramatically recreates what Juno will experience as it orbits Jupiter. By using their cell phone cameras, viewers can see lightning “storms” hidden beneath upper, opaque layers of “atmosphere”… in much the same way Juno will.
Goods explains: “Humans are only able to see a little, tiny sliver of what there is available in light. There’s gamma rays, microwaves, ultraviolet and infrared light also, and infrared is close enough to the visible part of the spectrum that cell phone cameras can pick it up. Cell phones normally produce more grainy photos at night because they don’t try to cut out the infrared light the way higher-end digital cameras do so in this case, the cell phone cameras are an advantage.” (Via the Pasadena Weekly.)
I had a chance to meet Dan Goods during a Tweetup event for the Juno launch at Kennedy Space Center. He’d brought a table that had magnetic elements set beneath a flat black surface, and by passing a handheld magnet over the table you could “detect” the different magnetic fields… in some cases rather strongly, even though they were all obviously invisible. It was an ingenious way that Juno’s abilities could be demonstrated in a “hands-on” manner.
Beneath the Surface takes that kind of demonstration to an entirely new level.
“I love to work with the world of things that are right in front of you but you just can’t see,” Goods said. “With Juno, there’s all this structure just under the surface of Jupiter, but humans can develop tools that help us understand things we’d never have seen before.”
The exhibit was installed at the Pasadena Museum of California Art until January 8. It will now travel to science museums around the country.
Juno’s primary goal is to improve our understanding of Jupiter’s formation and evolution. The spacecraft will spend a year investigating the planet’s origins, interior structure, deep atmosphere and magnetosphere. Juno’s study of Jupiter will help us to understand the history of our own solar system and provide new insight into how planetary systems form and develop in our galaxy and beyond.
A year ago, 2011 was proclaimed as the “Year of the Solar System” by NASA’s Planetary Science division. And what a year of excitement it was indeed for the planetary science community, amateur astronomers and the general public alike !
NASA successfully delivered astounding results on all fronts – On the Story of How We Came to Be.
“2011 was definitely the best year ever for NASA Planetary Science!” said Jim Green in an exclusive interview with Universe Today. Green is the Director of Planetary Science for the Science Mission Directorate at NASA HQ. “The Search for Life is a significant priority for NASA.”
This past year was without doubt simply breathtaking in scope in terms of new missions, new discoveries and extraordinary technical achievements. The comprehensive list of celestial targets investigated in 2011 spanned virtually every type of object in our solar system – from the innermost planet to the outermost reaches nearly touching interplanetary space.
There was even a stunningly evocative picture showing “All of Humanity” – especially appropriate now in this Holiday season !
Three brand new missions were launched and ongoing missions orbited a planet and an asteroid and flew past a comet.
“NASA has never had the pace of so many planetary launches in such a short time,” said Green.
And three missions here were awarded ‘Best of 2011’ for innovation !
Here’s the Top NASA Planetary Science Stories of 2011 – ‘The Year of the Solar System’ – in chronological order
1. Stardust-NExT Fly By of Comet Tempel 1
Starting from the first moments of 2011 at the dawn of Jan. 1, hopes were already running high for planetary scientists and engineers busily engaged in setting up a romantic celestial date in space between a volatile icy comet and an aging, thrusting probe on Valentine’s Day.
The comet chasing Stardust-Next spacecraft successfully zoomed past Comet Tempel 1 on Feb. 14 at 10.9 km/sec (24,000 MPH) after flying over 6 Billion kilometers (3.5 Billion mi).
The craft approached within 178 km (111mi) and snapped 72 astonishingly detailed high resolution science images over barely 8 minutes. It also fulfilled the teams highest hopes by photographing the human-made crater created on Tempel 1 in 2005 by a cosmic collision with a penetrator hurled by NASA’s Deep Impact spacecraft. The probe previously flew by Comet Wild 2 in 2004 and returned cometary coma particles to Earth in 2006
Tempel 1 is the first comet to be visited by two spaceships from Earth and provided the first-ever opportunity to compare observations on two successive passages around the Sun.
Don Brownlee, the original Principal Investigator, summarized the results for Universe Today; “A great bonus of the mission was the ability to flyby two comets and take images and measurements. The wonderfully successful flyby of Comet Tempel 1 was a great cap to the 12 year mission and provided a great deal of new information to study the diversity among comets.”
“The new images of Tempel showed features that form a link between seemingly disparate surface features of the 4 comets imaged by spacecraft. Combining data on the same comet from the Deep Impact and Stardust missions has provided important new insights in to how comet surfaces evolve over time and how they release gas and dust into space”.
2. MESSENGER at Mercury
On March 18, the Mercury Surface, Space Environment, Geochemistry, and Ranging, or MESSENGER, spacecraft became the first spacecraft inserted into orbit around Mercury, the innermost planet.
So far MESSENGER has completed 1 solar day – 176 Earth days- circling above Mercury. The probe has collected a treasure trove of new data from the seven instruments onboard yielding a scientific bonanza; these include global imagery of most of the surface, measurements of the planet’s surface chemical composition, topographic evidence for significant amounts of water ice, magnetic field and interactions with the solar wind.
“MESSENGER discovered that Mercury has an enormous core, larger than Earth’s. We are trying to understand why that is and why Mercury’s density is similar to Earth’s,” Jim Green explained to Universe Today.
“The primary mission lasts 2 solar days, equivalent to 4 Mercury years.”
“NASA has granted a 1 year mission extension, for a total of 8 Mercury years. This will allow the team to understand the environment at Mercury during Solar Maximum for the first time. All prior spacecraft observations were closer to solar minimum,” said Green.
MESSENGER was launched in 2004 and the goal is to produce the first global scientific observations of Mercury and piece together the puzzle of how Mercury fits in with the origin and evolution of our solar system.
NASA’s Mariner 10 was the only previous robotic probe to explore Mercury, during three flyby’s back in the mid-1970’s early in the space age.
3. Dawn Asteroid Orbiter
The Dawn spacecraft achieved orbit around the giant asteroid Vesta in July 2011 after a four year interplanetary cruise and began transmitting the history making first ever close-up observations of the mysteriously diverse and alien world that is nothing short of a ‘Space Spectacular’.
“We do not have a good analog to Vesta anywhere else in the Solar System,” Chris Russell said to Universe Today. Russell, from UCLA, is the scientific Principal Investigator for Dawn.
Before Dawn, Vesta was just another fuzzy blob in the most powerful telescopes. Dawn has completely unveiled Vesta as a remarkably dichotomous, heavily battered and pockmarked world that’s littered with thousands of craters, mountains and landslides and ringed by mystifying grooves and troughs. It will unlock details about the elemental abundances, chemical composition and interior structure of this marvelously intriguing body.
Cataclysmic collisions eons ago excavated Vesta so it lacks a south pole. Dawn discovered that what unexpectedly remains is an enormous mountain some 16 miles (25 kilometers) high, twice the height of Mt. Everest.
Dawn is now about midway through its 1 year mission at Vesta which ends in July 2012 with a departure for Ceres, the largest asteroid. So far the framing cameras have snapped more than 10,000 never-before-seen images.
“What can be more exciting than to explore an alien world that until recently was virtually unknown!. ” Dr. Marc Rayman said to Universe Today. Rayman is Dawn’s Chief Engineer from NASA’s Jet Propulsion Lab (JPL) in Pasadena, Calif.
“Dawn is NASA at its best: ambitious, exciting, innovative, and productive.”
4. Juno Jupiter Orbiter
The solar powered Juno spacecraft was launched on Aug. 5 at Cape Canaveral Air Force Station in Florida, to embark on a five year, 2.8 billion kilometer (1.7 Billion mi) trek to Jupiter, our solar system’s largest planet. It was the first of three NASA planetary science liftoffs scheduled in 2011.
Juno’s goal is to map to the depths of the planets interior and elucidate the ingredients of Jupiter’s genesis hidden deep inside. These measurements will help answer how Jupiter’s birth and evolution applies to the formation of the other eight planets.
The 4 ton spacecraft will arrive at the gas giant in July 2016 and fire its braking rockets to go into a polar orbit and circle the planet 33 times over about one year.
The suite of nine instruments will scan the gas giant to find out more about the planets origins, interior structure and atmosphere, measure the amount of water and ammonia, observe the aurora, map the intense magnetic field and search for the existence of a solid planetary core.
“Jupiter is the Rosetta Stone of our solar system,” said Scott Bolton, Juno’s principal investigator from the Southwest Research Institute in San Antonio. “It is by far the oldest planet, contains more material than all the other planets, asteroids and comets combined and carries deep inside it the story of not only the solar system but of us. Juno is going there as our emissary — to interpret what Jupiter has to say.”
5. Opportunity reaches Endeavour Crater on Mars
The long lived Opportunity rover finally arrived at the rim of the vast 14 mile (22 kilometer) wide Endeavour Crater in mid-August 2011 following an epic three year trek across treacherous dune fields – a feat once thought unimaginable. All told, Opportunity has driven more than 34 km ( 21 mi) since landing on the Red Planet way back in 2004 for a mere 90 sol mission.
In November, the rover discovered the most scientifically compelling evidence yet for the flow of liquid water on ancient Mars in the form of a water related mineral vein at a spot dubbed “Homestake” along an eroded ridge of Endeavour’s rim.
Read my story about the Homestake discovery here, along with our panoramic mosaic showing the location – created by Ken Kremer and Marco Di Lorenzo and published by Astronomy Picture of the Day (APOD) on 12 Dec. 2011.
Watch for my upcoming story detailing Opportunity’s accomplishments in 2011.
6. GRAIL Moon Mappers
The Gravity Recovery and Interior Laboratory, or GRAIL mission is comprised of twin spacecraft tasked to map the moon’s gravity and study the structure of the lunar interior from crust to core.
The dynamic duo lifted off from Cape Canaveral on September 10, 2011 atop the last Delta II rocket that will likely soar to space from Florida. After a three month voyage of more than 2.5 million miles (4 million kilometers) since blastoff, the two mirror image GRAIL spacecraft dubbed Grail-A and GRAIL-B are sailing on a trajectory placing them on a course over the Moon’s south pole on New Year’s weekend.
Each spacecraft will fire the braking rockets for about 40 minutes for insertion into Lunar Orbit about 25 hours apart on New Year’s Eve and New Year’s Day.
Engineers will then gradually lower the satellites to a near-polar near-circular orbital altitude of about 34 miles (55 kilometers).
The spacecraft will fly in tandem and the 82 day science phase will begin in March 2012.
“GRAIL is a Journey to the Center of the Moon”, says Maria Zuber, GRAIL principal investigator from the Massachusetts Institute of Technology (MIT). “GRAIL will rewrite the book on the formation of the moon and the beginning of us.”
“By globally mapping the moon’s gravity field to high precision scientists can deduce information about the interior structure, density and composition of the lunar interior. We’ll evaluate whether there even is a solid or liquid core or a mixture and advance the understanding of the thermal evolution of the moon and the solar system,” explained co-investigator Sami Asmar to Universe Today. Asmar is from NASA’s Jet Propulsion Laboratory (JPL)
7. Curiosity Mars Rover
The Curiosity Mars Science Lab (MSL) rover soared skywards on Nov. 26, the last of 2011’s three planetary science missions. Curiosity is the newest, largest and most technologically sophisticated robotic surveyor that NASA has ever assembled.
“MSL packs the most bang for the buck yet sent to Mars.” John Grotzinger, the Mars Science Laboratory Project Scientist of the California Institute of Technology, told Universe Today.
The three meter long robot is the first astrobiology mission since the Viking landers in the 1970’s and specifically tasked to hunt for the ‘Ingredients of Life’ on Mars – the most Earth-like planet in our Solar System.
Video caption: Action packed animation depicts sequences of Curiosity departing Earth, the nail biting terror of the never before used entry, descent and landing on the Martian surface and then looking for signs of life at Gale Crater during her minimum two year expedition across hitherto unseen and unexplored Martian landscapes, mountains and craters.

Curiosity will gather and analyze samples of Martian dirt in pursuit of the tell-tale signatures of life in the form of organic molecules – the carbon based building blocks of life as we know it.
NASA is targeting Curiosity to a pinpoint touch down inside the 154 km (96 mile) wide Gale Crater on Aug. 6, 2012. The crater exhibits exposures of phyllosilicates and other minerals that may have preserved evidence of ancient or extant Martian life and is dominated by a towering 3 mile (5 km) high mountain.
“10 science instruments are all aimed at a mountain whose stratigraphic layering records the major breakpoints in the history of Mars’ environments over likely hundreds of millions of years, including those that may have been habitable for life,” Grotzinger told me.
This past year Ken was incredibly fortunate to witness the ongoing efforts of many of these magnificent endeavors.
– – Says Rob Manning, Curiosity Chief Engineer at NASA’s Jet Propulsion Laboratory in Pasadena, Calif – in an exclusive interview with Universe Today for all fans of Curiosity and the unprecedented voyage of Science and Discovery about to take flight to Mars on November 26. Manning was also the Chief Engineer for the Entry, Descent and Landing (EDL) of NASA’s phenomenally successful Spirit, Opportunity and Phoenix Mars robotic explorers.

Meet Rob and other JPL Mars engineers in the cool Video describing the ‘Challanges of Getting to Mars’ – below
Curiosity is NASA’s next Mars rover and her MMRTG nuclear power source has been installed at the launch pad through special access panels in the Atlas booster payload fairing and protective aeroshell on Nov. 17.
The huge 1-ton robot is now due to blastoff for the Red Planet on Saturday, November 26 at 10: 02 a.m. EST from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida. The launch window is open for one hour and 43 minutes.
Liftoff was postponed by one day to replace a battery in the on board flight termination system required in case the rocket were to veer off course.
Here is the very latest Curiosty update status from JPL’s Rob Manning as of Sunday evening – Nov. 20
“All seems well here at JPL in Pasadena,” Manning told me.
“We are having our last rehearsal at 1:30 a.m. on Monday, Nov 21.
“Weird ! As of a few hours ago the last human hands (in gloves) closed out the hatch door on the entry aeroshell and the two large doors in the rocket fairing have been closed. What is weird about it is that finally finally she is powered up and alone.”
“She has never been this alone before. Ironically all eyes are still upon her. Our team is monitoring her vitals 24-7,” Manning explained.
“The Challenges of Getting to Mars’ – Video caption: Meet Curiosity Chief Engineer Rob Manning and more members of the Curiosity Mars Rover Engineering Team at NASA’s Jet Propulsion Laboratory explain the final assembly of Curiosity at the Kennedy Space Center and how Curiosity will land use the rocket assisted Sky Crane.
“By this time next week, Curiosity will be heading for the home she was meant for.”
“Soon she will feel the cold walls of deep space on her radiators. The x-band transmitter and receiver will have an broken view of the sky (with Earth but a shiny blue dot off to her left). The penetrating rays of the sun will push electrons out of the solar panels and keep her battery charged. (And perhaps a few solar flares will pass by, just to keep things interesting.)”
“Earth can be a rough place for a rover not designed for our planet. Worse are those of us who have poked and prodded, tested beyond spec and pushed in ways that can only be done on Earth.”
“Sometimes we over-do it and push near the breaking point. We are not perfect after all but we need to know that she will do what needs to be done for her very own survival. Well she seems to have survived us.”
“Of course Curiosity will never really be alone. We are right there with her every step of the way. She is us.”
“I will be at JPL during launch,” said Manning.
The JPL team is also working day and night to insure that the do or die Mars Insertion burn fires as planned.
“Once the Deep Space Network acquires the signal, I want to be there to make sure that we did not fail her and that the transition from being the Atlas’s payload to interplanetary cruise is as painless as possible.”
“It will be a bit of a surprise if we did not have a bit of a surprise – but we are ready and so is Curiosity”
Curiosity and the Atlas V booster that will propel her to Mars will roll out to Launch Pad 41 at the Florida Space Coast on Friday morning, Nov. 24, the day after the Thanksgiving holiday.
NASA TV will carry the MSL launch live
After a 10 month interplanetary journey to Mars, Curiosity will plummet through the atmosphere and fire up the rocket powered descent stage and ‘Sky Crane’ to safely touchdown astride a layered mountain at the Gale Crater landing site in August 2012.
Curiosity has 10 science instruments to search for evidence about whether Mars has had environments favorable for microbial life, including the chemical ingredients for life. The unique rover will use a laser to look inside rocks and release the gasses so that its spectrometer can analyze and send the data back to Earth.

When it comes to space flight pedigrees, few companies have one that can compare to Aerojet’s. The California-based company has a resume on space operations that is as lengthy as it is impressive. Universe Today sat down with Julie Van Kleeck – the firm’s vice-president of space and launch systems business unit.
Van Kleeck spoke extensively about the company’s rich history, its legacy of accomplishments – as well as what it has planned for space missions of the future.
Universe Today:Hi Julie, thanks for taking the time to chat with us today.
Van Kleeck: “My pleasure!”
Universe Today:How long has Aerojet been in business and what exactly is it that your company produces?
Van Kleeck: “We’ve been in the space business – since there was a space program – so since at least the 50s. We’ve dealt with both launch systems as well as space maneuvering systems, those components that enable spacecraft to move while in space.”
Universe Today:What about in terms of human space flight, when did Aerojet get involved with that?
Van Kleeck: “We first started working on the manned side of the house back during the Gemini Program, from there we progressed to Apollo, then shuttle and we hope to be involved with SLS (Space Launch System) as well.”
Universe Today: I understand that your company also has an extensive history when it comes to unmanned missions as well, care to tell us a bit about that?
Van Kleeck: “We have been on every discovery mission that has ever been launched, we have touched every part of space that you can touch.”
Universe Today:Some aerospace companies only produce one product or service, why is Aerojet’s list of offerings so diversified?
Van Kleeck: “We’re quite different than our competitors in that we provide a very wide-range of products to our customers. We’ve provided the liquid engines that went on Titan and now we provide the solids that go on the Atlas V launch vehicle as well as the small chemical and electrical propulsion systems that are utilized on some satellites.”
Universe Today:Does this mean that Aerojet places more importance on one space flight system over others?
Van Kleeck: “We view each of the products that we produce as equally important. Having said that, the fact that Aerojet offers a diversity of products and understands each of them well – sets us apart from our competitors. Firms that only produce one type of product tend to work to sell just that one product, whereas Aerojet’s extensive catalog of services allows us to be more objective when offering those services to our customers.”
Universe Today:When you look back, what is one of the most interesting projects that Aerojet has been involved with?
Van Kleeck: “I think as I look back over the past decade, New Horizons comes to mind, it was the first Atlas to launch with five solids on it. I look at that mission in particular as a major accomplish for not just us – but the country as well.”
Universe Today:What does the future hold for Aerojet?
Van Kleeck: ”We’re working on the Orion crew capsule right now with both liquid propulsion for it as well as solid propulsion for the abort test motor. We’re very much looking forward to seeing Orion fly in the coming years. We are currently putting into place the basic infrastructure to support human space exploration. We are working with both commercial crewed as well as Robert Bigelow to provide propulsion systems that work with their individual system – because no one system fits everyone. We are pleased to be offer systems for a wide variety of space exploration efforts.”
Universe Today:Julie, thanks for taking the time to chat with us today!
Van Kleeck: “No problem at all – it was my pleasure!”
Aerojet’s products will be on full display Nov. 25 as, if everything goes as planned the Mars Science Laboratory (MSL) rover Curiosity is set to launch on that day. Four of the company’s solid rocket motors or SRMs will help power the Curiosity rover on its way to the red planet.
For a taste of what Aerojet’s SRMs provide – please view the NASA video below.
CAPE CANAVERAL, Fla — One of the more dramatic buildings operated by United Launch Alliance (ULA) at Kennedy Space Center in Florida is the Vertical Integration Facility or VIF as it is more commonly known. It is in this facility that expendable launch vehicles are brought, lying on their sides – and then hoisted into the vertical position for launch. The current resident in the VIF is the Atlas V 541 (AV-028) that is slated to launch the Mars Science Laboratory (MSL).
At the top of the 292 –foot-tall structure is a 60 ton crane that initially is used to lift the Atlas’ first stage into the vertical position. The payload, ensconced in the protective fairing, is assembled elsewhere. Once it arrives at the VIF, it is hoisted high into the air using the same crane and then mated with the top of the launch vehicle. Given the delicate nature of this operation technicians take their time in lifting the precious cargo and maneuvering it over the rocket.
“You get the most amazing view from the top of the VIF,” said Mike Woolley of United Launch Alliance. “From this level you can clearly see not just Launch Complex 41, but a great deal of Florida’s Space Coast.”
Once the fairing and its payload have been safely affixed to the top of the rocket, the doors are opened up and the Atlas V is then rolled out to the adjacent Space Launch Complex-41 (SLC-41).
“Once the Atlas V is fully assembled, the completed vehicle is rolled, in the vertical, out to the launch pad.” Woolley said.
Currently on the fifth level the upper part of the Centaur, the all-important rocket that will send the rover on its way to Mars, covered in a protective layer of white plastic, is visible.
Descending down the length of the Atlas V, level by level one gains an appreciation for the sheer scale of the Atlas rocket, its solid rocket motors and the attention to detail needed to launch payloads out of Earth’s gravity well.
On Level One the top of the Atlas’ Solid Rocket Motors (SRMs) produced by Aerojet are visible. At the ground floor, one has the ability to look up (somewhat, platforms and rigging block your view) the length of the rocket. On the ground level, one can plainly see that the twin RD-180 engines are Russian-made – the Cyrillic lettering still grace the engines’ nozzles.
MSL is the next planetary mission on NASA’s docket, more commonly known as “Curiosity” is a nuclear-powered rover about the size of a compact automobile.
Curiosity is currently slated for a Nov. 25 launch date at 10:21 a.m. EDT from Cape Canaveral Air Force Station’s Space Launch Complex 41 (SLC-41). Members of the media (myself included) got to see the Atlas for this launch being lifted into the air in preparation for the November launch when we were being escorted back to the NASA/LSC press site after the GRAIL launch was scrubbed (GRAIL would go on to be launched two days later).
[/caption]CAPE CANAVERAL, Fla – The photographers that cover the events that take place in and around Florida’s Space Coast come from diverse backgrounds. However, when it comes to the passion that attracts so many to Cape Canaveral Air Force Station and Kennedy Space Center – their origins are very similar.
Many amateur photographers like Mike Killian have always been interested in spaceflight, in capturing the spectacle of launch. Like Killian, these photographers start out not knowing how to get onto Kennedy Space Center to shoot the launches and other events that take place there. They work out arrangements with NASA friends to get close and then, finally, they get affiliated with an accredited news organization (in Killian’s case the ARES Institute).
“I have loved the space program since I was a child,” Killian said. “Most folks that come out here and do this I doubt very highly that they do it thinking they will get rich. They do it because what they are showing the world is so important, so awe-inspiring…and so beautiful.”
Killian has only covered the space program as a photographer for a relatively short time, about three years. During that time however – he has covered some pivotal points in space flight history. The last flights of the space shuttle era, the launch of spacecraft to Earth orbit, the Moon and soon Mars. Killian, also like his compatriots, sacrifices long hours and endures low pay to capture images of these events. But when he gets that perfect shot of solid rocket boosters separating from an Atlas V on its way to orbit, or the final landing of the space shuttle – it is all worth it.
“Photography is pretty much like anything else,” said Killian during a recent interview. “It’s all about timing – being at the right place – at the right time.”
One recurring theme that occurs in aerospace photography is – progression. Photographers will come out to KSC/CCAFS with their digital cameras, then they will buy a more powerful camera and then they move on to remote cameras. When one hears remote they think the cameras are far away – the truth is that these cameras are extremely close. “Remote” means that they are remotely activated – generally by either a sound or light sensor.
Killian employs 2 Canon Rebel XSi cameras due to the camera’s affordability and versatility.
The 27-year-old, unlike many of his colleagues, does have a favorite image – and it isn’t even one that he took on Kennedy Space Center proper.
“My favorite shot thus far is of a lightning storm over KSC for the night launch of Discovery on STS-128. That storm scrubbed the launch attempt, but the images I captured that night were unreal,” said Killian. “This particular photo has so much going on – Discovery basking in xenon lights atop launch pad 39A fully fueled with her crew onboard, lightning racing through the clouds directly above KSC, & the shuttle training aircraft flying over the storm (upper left of photo) on weather recon trying to determine if there would be any chance the storm could let up in time to support a launch that night. It’s very unique, not your typical launch photo.”
For Killian photographing the space program allows him to both combine his love of photography with the driving interest that he has for space flight. Killian has no plans to stop photographing the space program anytime soon. For him this is not about the money, it’s about the history of thunder and the wonder of light and like so many of his fellow photojournalists he feels privileged to be able to do what he does.
