The European Space Agency’s (ESA) Rosetta spacecraft is at last rapidly closing in on its target destination, Comet 67P/Churyumov-Gerasimenko, after a decade long chase of 6.4 billion kilometers through interplanetary space. See imagery above and below.

As of today, Friday, August 1, ESA reports that Rosetta has approached the ‘rubber ducky looking’ comet to within a distance of less than 1153 kilometers. That distance narrows with each passing moment as the speeding robotic probe moves closer and closer to the comet while looping around the sun at about 55,000 kilometers per hour (kph).

Rosetta is now just 5 days away from becoming Earth’s first probe ever to rendezvous and enter orbit around a comet.

See above our image collage of Rosetta nearing final approach with the spacecrafts most recent daily Navcam camera images, all taken within the past week starting on July 25 and including up to the most recently release image snapped on July 31. The navcam images are all to scale to give the sense of the spacecraft approaching the comet and revealing ever greater detail as it grows in apparent size in the cameras field of view. The navcam images were also taken at about the same time of day each day.

The highest resolution navcam image yet of the two lobed comet – merged at a bright band – was taken on July 31 from a distance of 1327 kilometers and published within the past few hours by ESA today, Aug 1. It shows the best view yet of the surface features of the mysterious bright necked wanderer composed of primordial ice, rock, dust and more.

The Navcam collage is combined with an OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) wide angle camera view of the comet and its asymmetric coma of ice and dust snapped on July 25 from a distance of around 3000 km, and with an exposure time of 300 seconds. The OSIRIS image covers an area of about 150 x 150 km (90 mi x 90 mi). The images have been contrast enhanced to bring out more detail.

Scientists speculate that the comets bright neck region could be caused by differences in material or grain size or topological effects.

Rosetta’s history making orbital feat is slated for Aug. 6 following the final short duration orbit insertion burns on Aug. 3 and Aug. 6 to place Rosetta into orbit at an altitude of about 100 kilometers (62 miles) where it will study and map the 4 kilometer wide comet for some 17 months.

The comet rotates around once every 12.4 hours.

“If any glitches in space or on ground had delayed the most recent burns, orbital mechanics dictate that we’d only have had a matter of a few days to fix the problem, re-plan the burn and carry it out, otherwise we run the risk of missing the comet,” says Trevor Morley, a flight dynamics specialist at ESOC.

In November 2014 the Rosetta mothership will deploy the Philae science lander for the first ever attempt to land on a comet’s nucleus using harpoons to anchor itself to the surface while the comet is rotating.

As Rosetta edges closer on its final lap, engineers at mission control at the European Space Operations Centre (ESOC), in Darmstadt, Germany have commanded the probes navigation camera (navcam) to capture daily images while the other science instruments also collect measurements analyzing the comets physical characteristics and chemical composition in detail.

The probe has already discovered that the comet’s surface temperature is surprisingly warm at –70ºC, which is some 20–30ºC warmer than predicted. This indicates the surface is too hot to be covered in ice and must instead have a dark, dusty crust, says ESA.

Comet 67P/Churyumov-Gerasimenko is a short period comet some 555 million kilometres from the Sun at this time, about three times further away than Earth and located between the orbits of Jupiter and Mars.

You can watch the Aug. 6 orbital arrival live via a livestream transmission from ESA’s spacecraft operations centre in Darmstadt, Germany.

While you were reading this the gap between the comet and Rosetta closed to less than 1000 kilometers!

NASA Announces Science Instruments for Mars 2020 Rover Expedition to the Red Planet

NASA announced the winners of the high stakes science instrument competition to fly aboard the Mars 2020 rover at a briefing held today, Thursday, July 31, at the agency’s headquarters in Washington, D.C.

The 2020 rover’s instruments goals are to search for signs of organic molecules and past life and help pave the way for future human explorers.

Seven carefully-selected payloads were chosen from a total of 58 proposals received in January 2014 from science teams worldwide, which is twice the usual number for instrument competitions and demonstrates the extraordinary interest in Mars by the science community.

The 2020 rover architecture is based on NASA’s hugely successful Mars Science Laboratory (MSL) Curiosity rover which safely touched down a one ton mass on Mars on Aug. 5, 2012 using the nail-biting and never before used skycrane rocket assisted descent system.

The seven instruments will conduct unprecedented science and technology investigations on the Red Planet that’s aimed for the first time at simultaneously advancing both NASA’s unmanned robotic exploration searching for extraterrestrial life and plans for human missions to Mars in the 2030’s.

Planning for NASA's 2020 Mars rover envisions a basic structure that capitalizes on the design and engineering work done for the NASA rover Curiosity, which landed on Mars in 2012, but with new science instruments selected through competition for accomplishing different science objectives.

The instruments will have the capability to detect low levels of organic molecules that are essential precursors to life.

A technology demonstration experiment will use Mars natural resources to generate oxygen from atmospheric carbon dioxide that can be used as rocket fuel or for human explorers. This will save enormous costs by enabling astronauts to ‘live off the land’ rather than having to bring everything needed for survival from Earth.

NASA said that the development cost for the chosen instruments is approximately $130 million out of a total cost of $1.9 Billion.

This overall cost is less than Curiosity’s approximate $2.4 Billion cost since the team is rebuilding the rover and landing architecture – sort of an MSL 2 so to speak – developed for Curiosity and also using several left over MSL flight spares.

The Mars 2020 rover will also have a sample cacher with the ability to store core samples collected by the rover’s drill for later retrieval and return to Earth at an as yet unspecified time.

“The Mars 2020 rover, with these new advanced scientific instruments, including those from our international partners, holds the promise to unlock more mysteries of Mars’ past as revealed in the geological record,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington.

“This mission will further our search for life in the universe and also offer opportunities to advance new capabilities in exploration technology.”

Here’s a list of the 7 selected science payload proposals. They are in some ways more advanced versions form Curiosity and in other ways completely new:

Mastcam-Z, an advanced camera system with panoramic and stereoscopic imaging capability with the ability to zoom. The instrument also will determine mineralogy of the Martian surface and assist with rover operations. The principal investigator is James Bell, Arizona State University in Phoenix.

SuperCam, an instrument that can provide imaging, chemical composition analysis, and mineralogy. The instrument will also be able to detect the presence of organic compounds in rocks and regolith from a distance. The principal investigator is Roger Wiens, Los Alamos National Laboratory, Los Alamos, New Mexico. This instrument also has a significant contribution from the Centre National d’Etudes Spatiales,Institut de Recherche en Astrophysique et Planetologie (CNES/IRAP) France.

Planetary Instrument for X-ray Lithochemistry (PIXL), an X-ray fluorescence spectrometer that will also contain an imager with high resolution to determine the fine scale elemental composition of Martian surface materials. PIXL will provide capabilities that permit more detailed detection and analysis of chemical elements than ever before. The principal investigator is Abigail Allwood, NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals (SHERLOC), a spectrometer that will provide fine-scale imaging and uses an ultraviolet (UV) laser to determine fine-scale mineralogy and detect organic compounds. SHERLOC will be the first UV Raman spectrometer to fly to the surface of Mars and will provide complementary measurements with other instruments in the payload. The principal investigator is Luther Beegle, JPL.

The Mars Oxygen ISRU Experiment (MOXIE), an exploration technology investigation that will produce oxygen from Martian atmospheric carbon dioxide. The principal investigator is Michael Hecht, Massachusetts Institute of Technology, Cambridge, Massachusetts.

Mars Environmental Dynamics Analyzer (MEDA), a set of sensors that will provide measurements of temperature, wind speed and direction, pressure, relative humidity and dust size and shape. The principal investigator is Jose Rodriguez-Manfredi, Centro de Astrobiologia, Instituto Nacional de Tecnica Aeroespacial, Spain.

The Radar Imager for Mars’ Subsurface Exploration (RIMFAX), a ground-penetrating radar that will provide centimeter-scale resolution of the geologic structure of the subsurface. The principal investigator is Svein-Erik Hamran, Forsvarets Forskning Institute, Norway.

So the instruments are more sophisticated, upgraded hardware versions as well as new instruments to conduct geological assessments of the rover’s landing site, determine the potential habitability of the environment, and directly search for signs of ancient Martian life, according to NASA.

Creating a Returnable Cache of Martian Samples is a major objective for NASA's Mars 2020 rover. This prototype show hardware to cache samples of cores drilled from Martian rocks for possible future return to Earth. The 2020 rover would be to collect and package a carefully selected set of up to 31 samples in a cache that could be returned to Earth by a later mission. The capabilities of laboratories on Earth for detailed examination of cores drilled from Martian rocks would far exceed the capabilities of any set of instruments that could feasibly be flown to Mars. The exact hardware design for the 2020 mission is yet to be determined. For scale, the diameter of the core sample shown in the image is 0.4 inch (1 centimeter).

“Today we take another important step on our journey to Mars,” said NASA Administrator Charles Bolden.

“While getting to and landing on Mars is hard, Curiosity was an iconic example of how our robotic scientific explorers are paving the way for humans to pioneer Mars and beyond. Mars exploration will be this generation’s legacy, and the Mars 2020 rover will be another critical step on humans’ journey to the Red Planet.”

Scientists Discover 101 Geysers Erupting at Saturn’s Intriguing Icy Moon Enceladus

This dramatic view looks across the region of Enceladus' geyser basin and down on the ends of the Baghdad and Damascus fractures that face Saturn. The image, which looks approximately in the direction of Saturn, was taken from a more elevated viewpoint than other Cassini survey images of this area of the moon's south pole.

Scientists analyzing the reams of data from NASA’s Cassini orbiter at Saturn have discovered 101 geysers erupting from the intriguing icy moon Enceladus and that the spewing material of liquid water likely originates from an underground sea located beneath the tiny moons ice shell, according to newly published research.

The geysers are composed of tiny icy particles, water vapor and trace amounts of simple organic molecules. They were first sighted in Cassini imagery snapped during flyby’s of the 310-mile-wide (500 kilometers wide) moon back in 2005 and immediately thrust Enceladus forward as a potential abode for alien life beyond Earth and prime scientific inquisition.

Liquid water, organic molecules and an energy source are the key requirements for life as we know it.

The eruptions emanated from a previously unknown network of four prominent “tiger stripe” fractures, named Damascus, Baghdad, Cairo and Alexandria sulci, located at the south polar region of Saturn’s sixth largest moon.

Using imagery gathered over nearly seven years of surveys by Cassini’s cameras, researchers generated a survey map of the 101 geysers erupting from the four tiger strips.

This artist's rendering shows a cross-section of the ice shell immediately beneath one of Enceladus' geyser-active fractures, illustrating the physical and thermal structure and the processes ongoing below and at the surface.

The new findings and theories on the physical nature of how the geysers erupt have been published in two articles in the current online edition of the Astronomical Journal.

Scientists had initially postulated that the origin of the geysers could be frictional heating generated from back and forth rubbing of the opposing walls of the tiger stripe fractures that converted water ice into liquids and vapors. Another theory held that the opening and closing of the fractures allowed water vapor from below to reach the surface.

The geysers locations was eventually determined to coincide with small local hot spots erupting from one of the tiger stripe fractures after researchers compared low resolution thermal emission maps with the geysers’ locations and found the greatest activity at the warmest spots.

After later high-resolution data was collected in 2010 by Cassini’s heat-sensing instruments the geysers were found to coincide with small-scale hot spots, measuring only a few dozen feet (or tens of meters) across.

“Once we had these results in hand we knew right away heat was not causing the geysers, but vice versa,” said Carolyn Porco, leader of the Cassini imaging team from the Space Science Institute in Boulder, Colorado, and lead author of the first paper. “It also told us the geysers are not a near-surface phenomenon, but have much deeper roots.”

This graphic shows a 3-D model of 98 geysers whose source locations and tilts were found in a Cassini imaging survey of Enceladus' south polar terrain by the method of triangulation. While some jets are strongly tilted, it is clear the jets on average lie in four distinct "planes" that are normal to the surface at their source location.

“Thanks to recent analysis of Cassini gravity data, the researchers concluded the only plausible source of the material forming the geysers is the sea now known to exist beneath the ice shell. They also found that narrow pathways through the ice shell can remain open from the sea all the way to the surface, if filled with liquid water,” according to a NASA press release.

These are very exciting results in the search for life beyond Earth and clearly warrant a follow up mission.

“In casting your sights on the geysering glory of Enceladus, you are looking at frozen mist that originates deep within the solar system’s most accessible habitable zone,” writes Porco in her Captain’s Log summary of the new findings.

The Cassini-Huygens mission is a cooperative project between NASA, the European Space Agency (ESA) and the Italian Space Agency (ASI). Cassini was launched by a Titan IV rocket in 1997 and arrived at Saturn in 2004.

In 2005 Cassini deployed the Huygens probe which landed on Titan, Saturn’s largest moon sporting oceans of organic molecules and another prime location in the search for life.

The Cassini mission will conclude in 2017 with an intentional suicide dive into Saturn to prevent contamination on Titan and Enceladus – but lots more breathtaking science will be accomplished in the meantime!

Book Review: Neil Armstrong – A Life of Flight by Jay Barbree

“Neil Armstrong – A Life of Flight” is a thoroughly enjoyable new biography about the first human to set foot on the Moon on NASA’s Apollo 11 mission written with gusto by Emmy winning NBC News space correspondent Jay Barbree.

Jay Barbee is a veteran NBC News reporter who has covered America’s manned space program from the start. And he has the distinction of being the only reporter to cover every single American manned space launch – all 166 from Alan Shepard in 1961 to STS-135 in 2011 – from his home base at the Kennedy Space Center in Florida allowing him to draw on a wealth of eyewitness experiences and inside contacts.

The book’s publication coincides with the 45th anniversary of the Flight of Apollo 11 on America’s first manned moon landing mission in July 1969 by the three man crew comprising Commander Neil Armstrong, fellow moonwalker and Lunar Module Pilot Buzz Aldrin and Command Module pilot Michael Collins.

It’s a meticulously researched book over five decades in the making and based on personal interviews, notes, meetings, remembrances, behind the scenes visits, launches and more between Neil Armstrong and his trusted friend Jay Barbree as well as hordes more officials and astronauts key to achieving NASA’s spaceflight goals.

He won that trust because the astronauts and others trusted that he would get the story right and never betray confidences, Jay told me in an interview about the book.

“This is really Neil’s book. And it’s as accurate as possible. I will never reveal something Neil told me in confidence. But there is far more in this book about Neil than he would have liked.”

XIX — Jay Barbree and Neil Armstrong enjoy dinner with America’s first in orbit, John Glenn, who is performing standup comedy out of the picture. Courtesy: Jay Barbree. See p. XIX

There is a six page list of acknowledgments and the forward is written by no less than John Glenn – the first American to orbit the Earth in 1962.

Barbree is a master story teller who amply illustrates why NASA felt Armstrong was the best candidate to be 1st Man on the Moon based on his extraordinary intellect, piloting skills, and collected coolness and clear thinking under extraordinary pressure.

Armstrong also always shied away from publicity and bringing attention to himself, Barbree told me.

“Neil did not think he was any more important than anyone else. Neil wanted to do a book about a life of flight. But he wanted everyone else included.” And that’s exactly the format for the book – including Armstrong’s colleagues in words and pictures.

On July 21, NASA officially renamed a historic human spaceflight facility at the Kennedy Space Center in honor of Mission Commander Neil Armstrong – read my story here.

Barbree details Armstrong’s lifetime of flight experiences that led to the ultimate Moon landing moment; starting with his early experiences as a Korean war combat pilot and bailing out of a crippled Panther F9F fighter plane, flying the X-15 to an altitude of 39 miles and the edge of space as a NASA test pilot, his selection as a member of the second group of astronauts on September 17, 1962, his maiden space mission on Gemini 8 which suddenly went out of control and threatened the crews lives, and finally the landing on the Sea of Tranquility with only 30 seconds of fuel remaining.

“Neil Armstrong – A Life of Flight” is a book for anyone interested in learning the nitty gritty inside details starting from the founding of America’s space effort, the trials, tribulations and triumphs of the earlier Mercury and Gemini manned programs, the terrible tragedy of the Apollo 1 fire and death of three brave Americans – Gus Grissom, Ed White and Roger Chaffee – and how all this swirl lead up to America’s determined and miraculous effort recounting how we got to the Moon. Go elsewhere for gossip.

This hefty 350 page volume is absolutely chock full of details including copious quotes on virtually every page. So much so that Barbree brings the along reader for what seems like a firsthand account. It’s as though he were a fly in the room listening in on history being made and transcribing it second by second or as an actual crew member riding along himself and reporting ultimately from aboard Apollo 11 and the Moon’s desolate surface.

On the Lunar Surface – Apollo 11 astronauts trained on Earth to take individual photographs in succession in order to create a series of frames that could be assembled into panoramic images. This frame from fellow astronaut Buzz Aldrin’s panorama of the Apollo 11 landing site is the only good picture of mission commander Neil Armstrong on the lunar surface. Credit: NASA

Barbree does this by putting into context the full meaning and breadth of what’s happening on a moment by moment basis. Giving you the reader a complete understanding of what, why and how these history making events transpired as they did.

I found his background information endlessly illuminating and informative ! – precisely because it’s not merely a transcription of dialogue.

Concerning the mild controversy regarding Armstrong’s actual first words spoken from the lunar surface, here’s excerpts from how Jay tells the story on p. 263:

“He had thought about one statement he judged had meaning and fit the historic occasion …. Neil had not made up his mind … he was undecided until he was faced with the moment.

Armstrong then lifted his left boot .. and set it down in moon dust.

“That’s one small step for man,” Neil said with a momentary pause. “One giant leap for mankind.”

What most didn’t know was that Neil had meant to say, “That’s one small step for a man,” and that set off an argument for years to come. Had a beep in transmission wiped it from our ears or had Neil nervously skipped the word?

Knowing Neil’s struggles with public speaking, I believe the latter, and with all the excitement … I’ve never been convinced Neil knew himself for sure,” Barbree wrote.

Towards the books conclusion, he writes of Armstrong; “No greater man walked among us. No better man left us informed answers. Neil taught us how to take care of our Earth-Moon system.”

I also enjoyed towards the end of the book where Jay includes Neil’s disappointment that we haven’t ventured beyond Earth orbit in over 4 decades and includes Neil’s personal testimony to Congress so we learn the detail of Armstrong thoughts – in his own words.

“I am persuaded that a return to the moon would be the most productive path to expanding the human presence in the solar system.”

Jay also pinpoints why we haven’t returned to the Moon; “lack of vision for the future” by Congress and Presidents “have kept astronauts locked in Earth orbit.”

It’s been my privilege to get to know Jay during my own space reporting from the press site at the Kennedy Space Center and interview him about his magnificent new book.

Morning on the Moon: Apollo 11 Showed How Far We Could Go

Armstrong passed away unexpectedly at age 82 on August 25, 2012 due to complications from heart bypass surgery. Read my prior tribute articles: here and here

Despite Armstrong’s premature passing, Barbree told me he had completed all the interviews.

“There isn’t anything that comes to mind about Neil Armstrong that I didn’t get to ask him,” Barbree told me.

James Webb Space Telescope’s Giant Sunshield Test Unit Unfurled First Time

GODDARD SPACE FLIGHT CENTER, MD – The huge Sunshield test unit for NASA’s James Webb Space Telescope (JWST) has been successfully unfurled for the first time in a key milestone ahead of the launch scheduled for October 2018.

Engineers stacked and expanded the tennis-court sized Sunshield test unit last week inside the cleanroom at a Northrop Grumman facility in Redondo Beach, California.

NASA reports that the operation proceeded perfectly the first time during the test of the full-sized unit.

The Sunshield and every other JWST component must unfold perfectly and to precise tolerances in space because it has not been designed for servicing or repairs by astronaut crews voyaging beyond low-Earth orbit into deep space, William Ochs, Associate Director for JWST at NASA Goddard told me in an exclusive interview.

The five layered Sunshield is the largest component of the observatory and acts like a parasol.

Its purpose is to protect Webb from the suns heat and passively cool the telescope and its quartet of sensitive science instruments via permanent shade to approximately 45 kelvins, -380 degrees F, -233 C.

The kite-shaped Sunshield provides an effective sun protection factor or SPF of 1,000,000. By comparison suntan lotion for humans has an SPF of 8 to 40.

The extreme cold is required for the telescope to function in the infrared (IR) wavelengths and enable it to look back in time further than ever before to detect distant objects.

The shield separates the observatory into a warm sun-facing side and a cold anti-sun side.

Its five thin membrane layers also provides a stable thermal environment to keep the telescopes 18 primary mirror segments properly aligned for Webb’s science investigations.

JWST is the successor to the 24 year old Hubble Space Telescope and will become the most powerful telescope ever sent to space.

The Webb Telescope is a joint international collaborative project between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA).

NASA has overall responsibility and Northrop Grumman is the prime contractor for JWST.

Webb will launch folded up inside the payload fairing of an ESA Ariane V ECA rocket from the Guiana Space Center in Kourou, French Guiana.

In launch configuration, the Sunshield will surround the main mirrors and instruments like an umbrella.

During the post launch journey to the L2 observing orbit at the second Sun-Earth Lagrange point nearly a million miles (1.5 million Km) from Earth, the telescopes mirrors and sunshield will begin a rather complex six month long unfolding and calibration process.

The science instruments have been mounted inside the ISIM science module and are currently undergoing critical vacuum chamber testing at NASA Goddard Space Flight Center which provides overall management and systems engineering.

NASA Preps for Nail-biting Comet Flyby of Mars

This graphic depicts the orbit of comet C/2013 A1 Siding Spring as it swings around the sun in 2014. On Oct. 19, the comet will have a very close pass at Mars. Its nucleus will miss Mars by about 82,000 miles (132,000 kilometers). The comet's trail of dust particles shed by the nucleus might be wide enough to reach Mars or might also miss it.

As Comet C/2013 A1 Siding Spring inches closer to the Red Planet, NASA’s taking steps to protect its fleet of orbiting Mars spacecraft. On October 19, the comet’s icy nucleus will miss the planet by just 82,000 miles (132,000 km). That’s 17 times closer than the closest recorded Earth-approaching comet, Lexell’s Comet in 1770.

No one’s worried about the tiny nucleus doing any damage. It’ll zip right by. Rather it’s dust particles embedded in vaporizing ice that concern NASA planners. Dust spreads into a broad tail that could potentially brush Mars’ upper atmosphere and strike an orbiter. A single particle of debris half a millimeter across may not seem like your mortal enemy, but when it’s traveling at 35 miles (56 km) per second relative to the spacecraft, one hit could spell trouble.

“Three expert teams have modeled this comet for NASA and provided forecasts for its flyby of Mars,” explained Rich Zurek, chief scientist for the Mars Exploration Program at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The hazard is not an impact of the comet nucleus, but the trail of debris coming from it. Using constraints provided by Earth-based observations, the modeling results indicate that the hazard is not as great as first anticipated. Mars will be right at the edge of the debris cloud, so it might encounter some of the particles — or it might not.”

The agency’s taking a prudent approach. NASA currently operates the Mars Reconnaissance Orbiter (MRO) and Mars Odyssey spacecraft with a third orbiter, MAVEN, currently on its way to the planet and expected to settle into orbit a month before the comet flyby. Teams operating the orbiters plan to have all spacecraft positioned on the opposite side of Mars when the comet is most likely to pass by.

Already, mission planners tweaked MRO’s orbit on July 2 to move it toward a safe position with a second maneuver to follow on August 27. A similar adjustment is planned for Mars Odyssey on August 5 and October 9 for the Mars Atmosphere and Volatile Evolution (MAVEN) probe. The time of greatest risk to the spacecraft is brief – about 20 minutes – when the widest part of the comet’s tail passes closest to the planet.

Will dust shed by the comet streak as meteors in the Martian sky on October 19? The rovers will be watching. Credit: NASA/JPL

One question I’m always asked is whether the Mars rovers are in any danger of dust-producing meteors in the comet’s wake. While the planet might get peppered with a meteor shower, its atmosphere is thick enough to incinerate cometary dust particles before they reach the surface, not unlike what happens during a typical meteor shower here on Earth. Rover cameras may be used to photograph the comet before the flyby and to capture meteors during the comet’s closest approach.

Despite concerns about dust, NASA knows a good opportunity when it sees one. In the days before and after the flyby, all three orbiters will conduct studies on the comet.

According to a recent NASA press release, instruments on MRO and Odyssey will examine the nucleus, coma and tail and possible effects on the Martian atmosphere:

“Odyssey will study thermal and spectral properties of the comet’s coma and tail. MRO will monitor Mars’ atmosphere for possible temperature increases and cloud formation, as well as changes in electron density at high altitudes and MAVEN will study gases coming off the comet’s nucleus as it’s warmed by the sun. The team anticipates this event will yield detailed views of the comet’s nucleus and potentially reveal its rotation rate and surface features.”

This is Comet Siding Spring’s first trip to the inner solar system. Expect exciting news as we peer up close at pristine ices and dust that have been locked in deep freeze since the time the planets formed.

The three man crew of NASA’s Apollo 11 splashed down in the Pacific Ocean 45 years ago today on July 24, 1969 – successfully concluding Earth’s first journey to land humans on another world and return them safely to our Home Planet.

Apollo 11 Commander Neil Armstrong became the first human to set foot on the Moon on July 20, 1969 after he stepped off the footpad of the Lunar Module Eagle soon after the start of the moonwalk EVA at 10:39 p.m. EDT and onto the lunar surface with his left foot at the Sea of Tranquility at 10:56 p.m. EDT. Lunar Module (LM) pilot Buzz Aldrin followed soon thereafter. They came in peace for all mankind!

The magnificent Lunar landing feat accomplished by US Apollo 11 astronauts Neil Armstrong and Buzz Aldrin marks the pinnacle of Mankind’s most momentous achievement.

The Apollo 11 crew consisting of Neil Armstrong, Buzz Aldrin and Command module pilot Michael Collins splashed down safely at 12:50 p.m. EDT on July 24 about 900 miles southwest of Hawaii in the North Pacific Ocean while seated inside the Command Module Columbia dangling at the end of a trio of massive parachutes that slowed their descent through the Earth’s atmosphere.

After a mission duration of 8 days, 3 hours, 18 minutes, 35 seconds from launch to landing the Apollo 11 crew were plucked from the ocean by helicopters from the USS Hornet recovery ship after splashdown only 12 nautical miles (24 km) away.

They had to don protective biological isolation garments (BIGs) in case they were infected by some unknown and potentially hazardous “moon germs.” Of course there were no pathogens, but this was not definitely known at the time.

After their return to Earth, the trio was scrubbed with a disinfect solution of sodium hypochlorite and had to remain in quarantine for 21 days inside a 30 feet (9.1 m) long quarantine facility known as the Lunar Receiving Laboratory (LRL).

They were welcomed back to Earth by President Nixon aboard the USS Hornet.

We’ve chronicled the journey of Apollo 11 and lunar touchdown on July 20, 1969 as well as this week’s renaming of a historic human spaceflight facility at the Kennedy Space Center in honor of Mission Commander Neil Armstrong.

Armstrong passed away at age 82 on August 25, 2012 due to complications from heart bypass surgery. Read my prior tribute articles: here and here

Here we’ve collected a gallery of the mission and ocean splashdown that brought Apollo 11 to a close and fulfilled the lunar landing quest set by a young President John F. Kennedy early in the decade of the 1960s.

The trio blasted off atop a 363 foot-tall Saturn V rocket from Launch Complex 39A on their bold, quarter of a million mile moon mission from the Kennedy Space Center , Florida on July 16, 1969.

The three-stage Saturn V generated 7.5 million pounds of thrust and propelled the trio into space and immortality.

Read my story about the deep sea recovery of the Apollo 11 first stage F-1 engines in 2013 – here.

The crew arrived in lunar orbit three days later on July 19, 1969, inside the docked Apollo 11 Command/Service and Lunar Modules (CSM/LM).

Armstrong and Aldrin then moved into the Lunar Module, undocked and safely touched down at the Sea of Tranquility on the lunar surface on July 20, 1969 at 4:18 p.m EDT as hundreds of millions across the globe watched in awe.

Six hours later Armstrong climbed down the LM ladder and stepped onto the Moon and into immortality.

Armstrong’s first words:

“That’s one small step for [a] man, one giant leap for mankind.”

During their 2 ½ hour long moonwalk Armstrong and Aldrin unveiled a plaque on the side of the lunar module. Armstrong read the words;

“Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

The duo collected about 50 pounds (22 kg) of priceless moon rocks and set out the first science experiments placed by humans on another world. The moon rocks were invaluable in informing us about the origin of the Earth – Moon system.

Here is NASA’s restored video of the Apollo 11 EVA on July 20, 1969:

Video Caption: Original Mission Video as aired in July 1969 depicting the Apollo 11 astronauts conducting several tasks during extravehicular activity (EVA) operations on the surface of the moon. The EVA lasted approximately 2.5 hours with all scientific activities being completed satisfactorily. The Apollo 11 EVA began at 10:39:33 p.m. EDT on July 20, 1969 when Astronaut Neil Armstrong emerged from the spacecraft first. While descending, he released the Modularized Equipment Stowage Assembly on the Lunar Module’s descent stage.

Altogether Armstrong and Aldrin spent about 21 hours on the moon’s surface. Then they said goodbye to the greatest adventure and fired up the LM ascent engine to rejoin Michael Collins circling above in the Apollo 11 Command Module.

“The whole world was together at that particular moment,” says NASA Administrator Charles Bolden in a CNN interview. “In spite of all we are going through there is hope!”

Historic Human Spaceflight Facility at Kennedy Renamed in Honor of Neil Armstrong – 1st Man on the Moon

45 years ago on July 20, 1969, NASA astronaut and Apollo 11 Commander Neil Armstrong became the first human being to set foot on another celestial body when he stepped off the Apollo 11 Lunar Module Eagle and onto our Moon’s utterly alien surface.

Today, July 21, 2014, NASA officially renamed a historic facility at the Kennedy Space Center vital to human spaceflight in honor of Neil Armstrong during a a 45th anniversary ceremony at what until today was known as the ‘Operations and Checkout Building’ or O & C.

On that first moonwalk, Armstrong was accompanied by fellow NASA astronaut Buzz Aldrin on a two and a half hour excursion that lasted into the early morning hours of July 21. They came in peace representing all mankind.

Today’s ceremony was broadcast on NASA TV and brought together numerous dignitaries including Armstrong’s surviving crewmates Buzz Aldrin and Command Module pilot Mike Collins, Apollo 13 Commander Jim Lovell who was also Apollo 11’s backup commander, NASA Administrator Charlie Bolden, Kennedy Space Center Director Bob Cabana, and Armstrong’s family members including his sons Rick and Mark Armstrong who all spoke movingly at the dedication.

They were joined via a live feed from space by two NASA astronauts currently serving aboard the International Space Station (ISS) – Expedition 40 crew member Rick Wiseman and Commander Steve Swanson.

The backdrop for the ceremony was the Orion crew capsule, NASA’s next generation human rated spaceflight vehicle which is currently being assembled in the facility and is set to launch on its maiden unmanned test flight in December 2014. Orion will eventually carry US astronauts on journey’s to deep space destinations to the Moon, Asteroids and Mars.

Many of Armstrong’s colleagues and other officials working on Orion and NASA’s human spaceflight missions also attended.

The high bay of what is now officially the ‘Neil Armstrong Operations and Checkout Building’ was built in 1964 and previously was known as the Manned Spacecraft Operations Building.

It has a storied history in human spaceflight. It was used to process the Gemini spacecraft including Armstrong’s Gemini 8 capsule. Later it was used during the Apollo program to process and test the command, service and lunar modules including the Apollo 11 crew vehicles that were launched atop the Saturn V moon rocket. During the shuttle era it housed the crew quarters for astronauts KSC training and for preparations in the final days leading to launch.

“45 years ago, NASA’s journey to land the first human on the Moon began right here,” NASA Administrator Charlie Bolden said at the ceremony. “It is altogether fitting that today we rename this facility the Neil Armstrong Operations and Checkout Building. Throughout his life he served his country as an astronaut, an aerospace engineer, a naval aviator, a test pilot and a university professor, and he constantly challenged all of us to expand the boundaries of the possible.”

“He along with his crewmates, Buzz Aldrin and Michael Collins, are a bridge from NASA’s historic journey to the moon 45 years ago to our path to Mars today.”

“Houston, Tranquility Base here. The Eagle has landed !,” Armstrong called out and emotional applause erupted at Mission Control – “You got a bunch of guys about to turn blue.”

Armstrong’s immortal first words:

“That’s one small step for [a] man, one giant leap for mankind.”

During their 2 ½ hours moonwalk Armstrong and Aldrin unveiled a plaque on the side of the lunar module. Armstrong read the words;

Michael Collins concluded the ceremony with this tribute:

“He would not have sought this honor, that was not his style. But I think he would be proud to have his name so closely associated with the heart and the soul of the space business.”

“On Neil’s behalf, thank you for what you do every day.”

Altogether a dozen Americans have walked on the Moon during NASA’s five additional Apollo lunar landing missions. No human has returned since the final crew of Apollo 17 departed the Moon’s surface in December 1972.

One legacy of Apollo is the International Space Station (ISS) where six astronauts and cosmonauts work together on science research to benefit mankind.

Notably, the Cygnus commercial cargo ship berthed at the ISS on the 45th anniversary of the Apollo 11 liftoff bringing over 3600 pounds of science experiments and supplies to the station.

NASA’s next big human spaceflight goals are building commercial ‘space taxis’ to low Earth orbit in this decade, an asteroid retrieval mission in the 2020s and voyages to Mars in the 2030s using the new SLS rocket and Orion deep space crew capsule currently under development.

Sparks Fly on Mars as Curiosity Laser Blasts Red Planet Rock – Photos/Video

NASA's Curiosity Mars rover used the Mars Hand Lens Imager (MAHLI) camera on its arm to catch the first images of sparks produced by the rover's laser being shot at a rock on Mars. Credit: NASA/JPL-Caltech/MSSS

Curiosity has zapped hundreds of Red Planet rocks with her powerful laser blaster during her lifetime and has now caught the sparks flying for the first time as they happened – as seen in new photos and video above and below released this week by NASA.

As the NASA rover’s million watt Chemistry and Camera (ChemCam) instrument fired multiple laser shots at a rock fortuitously named “Nova” the team commanded her arm-mounted Mars Hand Lens Imager (MAHLI) high resolution imaging camera to try and capture the action as it occurred, for the first time. And they succeeded.

Curiosity blasted the baseball sized “Nova” rock target over 100 times on July 12, 2014, or Sol 687.

Since the nail biting touchdown nearly two years ago on Aug. 5, 2012 inside Gale Crater, ChemCam has aimed the laser instrument at more than 600 rock or soil targets and fired more than 150,000 laser shots.

Here’s a NASA/JPL video showing the laser flash:

Video Caption: The sparks that appear on the baseball-sized rock (starting at :17) result from the laser of the ChemCam instrument on NASA’s Curiosity Mars rover hitting the rock. Credit: NASA/JPL-Caltech/MSSS

ChemCam is used to determine the composition of Martian rocks and soils at a distance of up to 25 feet (8 meters) yielding preliminary data for the scientists and engineers to decide if a target warrants up close investigation and in rare cases sampling and drilling activities.

ChemCam works through a process called laser-induced breakdown spectroscopy. The laser hits a target with pulses to generate sparks, whose spectra provide information about which chemical elements are in the target.

Successive laser shots are fired in sequence to gradually blast away thin layers of material. Each shot exposes a slightly deeper layer for examination by the ChemCam spectrometer.

As Curiosity fired deeper into “Nova” it showed an increasing concentration of aluminum as the sequential laser blasts penetrated through the uninteresting dust on the rock’s surface. Silicon and sodium were also detected.

“This is so exciting! The ChemCam laser has fired more than 150,000 times on Mars, but this is the first time we see the plasma plume that is created,” said ChemCam Deputy Principal Investigator Sylvestre Maurice, at the Research Institute in Astrophysics and Planetology, of France’s National Center for Scientific Research and the University of Toulouse, France, in a statement.

“Each time the laser hits a target, the plasma light is caught and analyzed by ChemCam’s spectrometers. What the new images add is confirmation that the size and shape of the spark are what we anticipated under Martian conditions.”

A Martian target rock called "Nova," shown here, displayed an increasing concentration of aluminum as a series of laser shots from NASA's Curiosity Mars rover penetrated through dust on the rock's surface. This pattern is typical of many rocks examined with the rover's laser-firing ChemCam.

The SUZ sized rover is driving as swiftly as possible to the base of Mount Sharp which dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

During Year 1 on Mars, Earth’s emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

To date, Curiosity’s odometer totals over 5.1 miles (8.4 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 166,000 images.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the treacherous sand dunes at the foothills of Mount Sharp sometime later this year.
