Opportunity, the Princess of Martian Robots, phoned home dusty new self portraits – above and below – of her beautiful bod basking in the utterly frigid sunshine during her 5th winter on the Red Planet whilst overlooking a humongous crater offering bountiful science.

NASA’s endearing robot is simultaneously carrying out an ambitious array of ground breaking science experiments this winter – providing insight into the mysterious nature of the Martian core – while sitting stationary until the energy augmenting rays of the springtime Sun shower down on Mars from the heavens above.

Opportunity’s current winter worksite is located at the rim of the vast crater named Endeavour, some 14 miles (22 kilometers) in diameter. The robot will remain parked for the winter on a slope at the north end of the crater rim segment called Cape York with an approximate 15-degree northerly tilt towards the life-giving sun to maximize solar energy production. The park-site is at an outcrop dubbed “Greeley Haven”, named in honor of Ronald Greeley, a beloved and recently deceased science team member.

The power killing dust buildup is readily apparent on the solar arrays and High Gain Antenna pictured in the new panoramic self-portraits of Opportunity’s wing-like deck. The red Martian dust also functions as a rather effective camouflage agent, sometimes blending the rover to near invisibility with the surface.

Opportunity is located on the north-facing slope of a site called "Greeley Haven." This is a mosaic of images taken by Opportunity's panoramic camera (Pancam) during the 2,811th to 2,814th Martian days, or sols, of the rover's mission (Dec. 21 to Dec. 24, 2011).

Indeed because Opportunity is covered with a thicker film of dust compared to her prior four Martian winters, the rover team was forced to employ the same “tilting” strategy they successfully used to keep her twin sister Spirit alive during her trio of Antarctic-like winters. This is the first winter that Opportunity did not have sufficient power to continue roving across the surface.

Since Opportunity is located just south of the Martian equator, the daylight hours for solar power generation are growing shorter until the southern Mars winter solstice occurs on March 30, 2012. As of mid- February 2012, the latest measure of solar array energy production was 274 watt-hours, compared to about 900 watt-hours at the start of the mission. See Solar Power energy graph below.

Power generation from the solar arrays has fluctuated up and down throughout Opportunity’s lifetime depending on when the completely unpredictable and fortuitous Martian wind storms chance by and miraculously clean the arrays of the rusty red dust.

The rover science team is ingeniously using the lack of movement to their advantage and Opportunity is still vigorously hard at work doing breakthrough research each and every day.

From her stationary position, Opportunity is conducting her first ever radio science Doppler tracking measurements to support geo-dynamic investigations and to elucidate the unknown structure of the Martian interior and core. The team was eager for the long awaited chance to carry out the radio tracking experiment with the High Gain Antenna (HGA) and determine if Mars core is liquid or solid. Months of data collection are required while the rover stays stationary.

“This winter science campaign will feature two way radio tracking with Earth to determine the Martian spin axis dynamics – thus the interior structure, a long-neglected aspect of Mars,” Ray Arvidson told Universe Today. Arvidson, of Washington University in St. Louis, is the deputy rover Principal Investigator.

Opportunity has nearly finished snapping the 13 filter, 360 degree stereo Greeley” panorama. The rover deployed the robotic arm onto the surface of the “Amboy” outcrop to collect multi-sol integrations with the Mössbauer Spectrometer and the largest ever mosaic campaign using the Microscopic Imager.

“We’ll do good science while we’re at Greeley Haven. But as soon as we catch a wind gust or the seasons change, we’ll be on our way again,” Steve Squyres told Universe Today. Squyres, of Cornell University is the rover Science Principal Investigator

“The Martian southern winter solstice occurs at the end of March. A few months after that date we will drive her off the outcrop and further explore Cape York,” Arvidson told me

The team will drive Opportunity in search of further evidence of the gypsum mineral veins like “Homestake” – indicative of ancient water flow – previously discovered at Cape York. Thereafter they’ll rove further south to investigate deposits of phyllosilicates, the clay minerals which stem from an earlier epoch when liquid water flowed on Mars eons ago and perhaps may have been more favorable to sustaining life.

Opportunity is now well into her 9th year exploring hitherto unknown terrain on Mars, far exceeding anyone’s expectation. She landed inside a tiny crater on Jan. 24. 2004 for what was expected to be a mission of merely 90 Martian days, or Sols.

Today is Martian Sol 2873, that’s 32 times beyond the rover designers “warranty” for NASA’s Opportunity rover.

Altogether, Opportunity has journeyed more than 21 miles (34 kilometers) across the Red Planet’s surface, marking the first overland expedition on another Planet. See our route map below.

Earth’s next Mars Rover – NOT Made in USA

Just days after President Obama met with brilliant High School students at the 2012 White House Science Fair to celebrate their winning achievements and encourage America’s Youth to study science and take up careers in the Science, Technology, Engineering and Math (STEM) technical fields, the Obama Administration has decided on deep budgets cuts slashing away the very NASA science programs that would inspire those same students to shoot for the Stars and Beyond and answer the question – Are We Alone ?

Last year, the Obama Administration killed Project Constellation, NASA’s Human Spaceflight program to return American astronauts to the Moon. This year, the President has killed NASA’s ExoMars Robotic Spaceflight program aimed at dispatching two ambitious missions to Mars in 2016 and 2018 to search for signs of life.

Both ExoMars probes involved a joint new collaboration with the European Space Agency (ESA) carefully crafted to share costs in hard times and get the most bang for the buck – outlined in my earlier Universe Today story, here.

Expert Scientists and Policy makers have been voicing their opinions.

President Obama meets America’s brightest Young Rocket Scientists
President Barack Obama hosted the winning science fair students from a range of nationwide competitions at the 2nd White House Science Fair on February 7, 2012. The ExoMars missions were eliminated from the NASA budget announced on Feb. 13, 2012.

All of NASA’s “Flagship” Planetary Science missions have now been cancelled in the 2013 Fiscal Year Budget proposed on Feb. 13, and others missions have also been curtailed due to the severe economy.

“There is no room in the current budget proposal from the President for new Flagship missions anywhere,” said John Grunsfeld, NASA’s Associate Administrator for Science at a NASA budget briefing for the media on Feb. 13.

ESA is now looking to partner with Russia as all American participation in ExoMars is erased due to NASA’ s forced pull out.

On Feb. 13, NASA’s Fiscal 2013 Budget was announced and the Obama Administration carved away nearly half the Mars mission budget. Altogether, funding for NASA’s Mars and Planetary missions in the Fiscal 2013 budget would be sliced by $300 million – from $1.5 Billion this year to $1.2 Billion in 2013. NASA was forced to gut the Mars program to pay for the cost overruns of the James Webb Space Telescope.

Mars rover scientist Prof. Jim Bell of Arizona State University and President of The Planetary Society (TPS) told Universe Today that “no one expects increases”, but cuts of this magnitude are “cause for concern”.

NASA’s robotic missions to Mars and other solar system bodies have been highly successful, resulted in fundamental scientific breakthroughs and are wildly popular with students and the general public.

“With these large proposed cuts to the NASA Mars exploration program, there will be a lot of cause for concern,” said Bell.

“The Mars program has been one of NASA’s crown jewels over the past 15 years, both in terms of science return on investment, and in terms of public excitement and engagement in NASA’s mission. It would also represent an unfortunate retreat from the kind of international collaboration in space exploration that organizations like The Planetary Society so strongly support.”

Bell and other scientists feel that any cuts should be balanced among NASA programs, not aimed only at one specific area.

“Certainly no one expects increasing budgets in these austere times, and it is not useful or appropriate to get into a battle of “my science is better than your science” among the different NASA Divisions and Programs.” Bell told me.

“However, it would be unfortunate if the burden of funding cuts were to befall one of NASA’s most successful and popular programs in a disproportionate way compared to other programs. As Ben Franklin said, “We should all hang together, or surely we will all hang separately.”

Bell added that science minded organizations should work with Congress to influence the debate over the coming months.

“Of course, this would only be an initial proposal for the FY13 and beyond budget. Over the winter, spring, and summer many professional and public organizations, like TPS, will be working with Congress to advocate a balanced program of solar system exploration that focuses on the most important science goals as identified in the recent NRC Planetary Decadal Survey, as well as the most exciting and publicly compelling missions that are supported by the public–who ultimately are the ones paying for these missions.”

“Let’s hope that we can all find a productive and pragmatic way to continue to explore Mars, the outer solar system, and our Universe beyond,” Bell concluded.

“The impact of the cuts … will be to immediately terminate the Mars deal with the Europeans,” said Scott Hubbard, of Stanford University and a former NASA planetary scientist who revived the agency’s Mars exploration program after failures in 1999, to the Washington Post. “It’s a scientific tragedy and a national embarrassment.”

“I encourage whoever made this decision to ask around; everyone on Earth wants to know if there is life on other worlds,” Bill Nye, CEO of The Planetary Society, said in a statement. “When you cut NASA’s budget in this way, you’re losing sight of why we explore space in the first place.”

“There is no other country or agency that can do what NASA does—fly extraordinary flagship missions in deep space and land spacecraft on Mars.” Bill Nye said. “If this budget is allowed to stand, the United States will walk away from decades of greatness in space science and exploration. But it will lose more than that. The U.S. will lose expertise, capability, and talent. The nation will lose the ability to compete in one of the few areas in which it is still the undisputed number one.”

Ed Weiler is NASA’s recently retired science mission chief (now replaced by Grunsfeld) and negotiated the ExoMars program with ESA. Weiler actually quit NASA specifically in opposition to the Mars Program cuts ordered by the Office of Management and Budget (OMB) and had these comments for CBS News;

“To me, it’s bizarro world,” Weiler said an interview with CBS News. “Why would you do this? The President of the United States, President Obama, declared Mars to be the ultimate destination for human exploration. Obviously, before you send humans to the vicinity of Mars or even to land on Mars, you want to know as much about the planet as you possibly can. … You need a sample return mission. The president also established a space policy a few years ago which had the concept of encouraging all agencies to have more and more foreign collaboration, to share the costs and get more for the same bucks.”

“Two years ago, because of budget cuts in the Mars program, I had to appeal to Europe to merge our programs. … That process took two long years of very delicate negotiations. We thought we were following the president’s space policy exactly. Congressional reaction was very positive about our activities. You put those factors in place and you have to ask, why single out Mars? I don’t have an answer.”

Space Analysts and Political leaders also weighed in:

“The president’s budget is just a proposal,” said Howard McCurdy, a space-policy specialist at American University in Washington to the Christian Science Monitor.

The cuts “reflect the new reality” in which the economy, budget deficits, and the federal debt have elbowed their way to the top of Washington’s agenda, McCurdy adds.

“You don’t cut spending for critical scientific research endeavors that have immeasurable benefit to the nation and inspire the human spirit of exploration we all have,” said Rep. John Culberson (R-Tex.). Texas is home to NASA’s Johnson Space Center.

Rep. Adam Schiff (D-CA), who represents the district that’s home to the Jet Propulsion Laboratory (JPL), released this statement following his meeting with NASA Administrator Charles Bolden to discuss the agency’s 2013 budget proposal:

“Today I met with NASA Administrator Charles Bolden to express my dismay over widespread reports that NASA’s latest budget proposes to dramatically reduce the planetary science program, and with it, ground breaking missions to Mars and outer planetary bodies like Jupiter’s icy moon Europa, and to inform him of my vehement opposition to such a move.”

“America’s unique expertise in designing and flying deep-space missions is a priceless national asset and the Mars program, one of our nation’s scientific crown jewels, has been a spectacular success that has pushed the boundaries of human understanding and technological innovation, while also boosting American prestige worldwide and driving our children to pursue science and engineering degrees in college.

“As I told the Administrator during our meeting, I oppose these ill-considered cuts and I will do everything in my power to restore the Mars budget and to ensure American leadership in space exploration.”

In an interview with the San Gabriel Valley Tribune, Schiff said, “What they’re proposing will be absolutely devastating to planetary science and the Mars program. I’m going to be fighting them tooth and nail. Unfortunately if this is the direction the administration is heading, it will definitely hurt JPL – that’s why I’m so committed to reversing this.”

NASA still hopes for some type of scaled back Mars missions in the 2016 to 2020 timeframe which will be outlined in an upcoming article.

In the meantime, the entire future of America’s Search for Life on the Red Planet now hinges on NASA’s Curiosity Mars Science Laboratory rover speeding thru interplanetary space and a pinpoint touchdown inside the layered terrain of Gale Crater on August 6, 2012.

Curiosity will be NASA’s third and last generation of US Mars rovers – 4th Generation Axed !

Europe scored a major space success with today’s (Feb. 13) flawless maiden launch of the brand new Vega rocket from Europe’s Spaceport in Kourou, French Guiana.

The four stage Vega lifted off on the VV01 flight at 5:00 a.m. EST (10:00 GMT, 11:00 CET, 07:00 local time) from a new launch pad in South America, conducted a perfectly executed qualification flight and deployed 9 science satellites into Earth orbit.

Vega is a small rocket launcher designed to loft science and Earth observation satellites.

The payload consists of two Italian satellites – ASI’s LARES laser relativity satellite and the University of Bologna’s ALMASat-1 – as well as seven picosatellites provided by European universities: e-St@r (Italy), Goliat (Romania), MaSat-1 (Hungary), PW-Sat (Poland), Robusta (France), UniCubeSat GG (Italy) and Xatcobeo (Spain).

Three of these cubesats were the first ever satellites to be built by Poland, Hungary and Romania. They were constructed by University students who were given a once in a lifetime opportunity by ESA to get practical experience and launch their satellites for free since this was Vega’s first flight.

The 30 meter tall Vega has been been under development for 9 years by the European Space Agency (ESA) and its partners, the Italian Space Agency (ASI), French Space Agency (CNES). Seven Member States contributed to the program including Belgium, France, Italy, the Netherlands, Spain, Sweden and Switzerland as well as industry.

ESA can now boast a family of three booster rockets that can service the full range of satellites from small to medium to heavy weight at their rapidly expanding South American Spaceport at the Guiana Space Center.

Vega joins Europe’s stable of launchers including the venerable Ariane V heavy lifter rocket family and the newly inaugurated medium class Russian built Soyuz booster and provides ESA with an enormous commercial leap in the satellite launching arena.

“In a little more than three months, Europe has increased the number of launchers it operates from one to three, widening significantly the range of launch services offered by the European operator Arianespace. There is not anymore one single European satellite which cannot be launched by a European launcher service,” said Jean-Jacques Dordain, Director General of ESA.

“It is a great day for ESA, its Member States, in particularly Italy where Vega was born, for European industry and for Arianespace.”

Dordain noted that an additional 200 workers have been hired in Guiana to meet the needs of Europe’s burgeoning space programs. Whereas budget cutbacks are forcing NASA and its contractors to lay off tens of thousands of people as a result of fallout from the global economic recession.

ESA has already signed commercial contracts for future Vega launches and 5 more Vega rockets are already in production.

Vega’s light launch capacity accommodates a wide range of satellites – from 300 kg to 2500 kg – into a wide variety of orbits, from equatorial to Sun-synchronous.

“Today is a moment of pride for Europe as well as those around 1000 individuals who have been involved in developing the world’s most modern and competitive launcher system for small satellites,” said Antonio Fabrizi, ESA’s Director of Launchers.

The North American continent is literally set ablaze in a confluence of Auroral and Manmade light captured in spectacular new videos snapped by the astronauts serving aboard the International Space Station (ISS).

The Expedition 30 crew has recently filmed lengthy sequences of images that are among the most stunning ever taken by astronauts flying in orbit some 240 miles (385 kilometers) over the United States and Canada.

[/caption]
Teams working at the Crew Earth Observations center at NASA’s Johnson Space Center in Houston, Texas have assembled hundreds of individual still images taken onboard the ISS into a series of amazing videos.

Two videos collected here focus on the East and West coasts of North America and show the path traveled by the station from the crew’s perspective as they photographed the light emitted by hundreds of millions of humans living below and the brilliant light of the Aurora Borealis shining above them.

Recently we highlighted a single night time snapshot of the East Coast and tens of millions of humans.

Now the NASA team has assembled the entire sequence of images taken on January 29, 2012 from 05:33:11 to 05:48:10 GMT into a video -see above.

The orbital pass runs from Central America just southwest of Mexico and continues to the North Atlantic Ocean, northeast of Newfoundland. It begins by looking over Central America towards the Gulf of Mexico and the southeastern United States. As the ISS travels northeast over the gulf, some southeastern United States cities can be distinguished, like New Orleans, Mobile, Jacksonville, and Atlanta. Continuing up the east coast, some northeastern states, like Washington, D.C., Baltimore, Philadelphia, and New York City stand out brightly along the coastline. The Aurora Borealis shines in the background as the pass finishes near Newfoundland

The 2nd video is titled “Across Southwest Canada at Night”

This sequence of shots was taken January 25, 2012 from 12:34:11 to 12:36:28 GMT, on a pass from near the border of British Columbia, Canada and Washington state, near Vancouver Island, to southern Alberta, near Calgary.

The main focus of this video is the Aurora Borealis over Canada, which appears very near the ISS during this short and exciting video.

And don’t forget the fabulous ISS shots of Comet Lovejoy taken in December 2011 by Expedition 30 Commander Dan Burbank.

Budget Axe to Gore America’s Future Exploration of Mars and Search for Martian Life

NASA Budget Cuts in Fiscal Year 2013 will force NASA to kill participation in the joint ESA/NASA collaboration to send two Astrobiology related missions to orbit and land rovers on Mars in 2016 and 2018 - designed to search for evidence of Life. Russia will likely replace the deleted Americans.

[/caption]

America’s hugely successful Mars Exploration program is apparently about to be gutted by Obama Administration officials wielding a hefty budget axe in Washington, D.C. Consequently, Russia has been invited to join the program to replace American science instruments and rockets being scrapped.

NASA’s Fiscal 2013 Budget is due to be announced on Monday, February 13 and its widely reported that the Mars science mission budget will be cut nearly in half as part of a significant decline in funding for NASA’s Planetary Science Division.

The proposed deep slash to the Mars exploration budget would kill NASA’s participation in two new missions dubbed “ExoMars” set to launch in 2016 and 2018 as a joint collaboration with the European Space Agency (ESA).

The ESA/NASA partnership would have dispatched the Trace Gas Orbiter to the Red Planet in 2016 to search for atmospheric methane, a potential signature for microbial life, and an advanced Astrobiology rover to drill deeper into the surface in 2018. These ambitious missions had the best chance yet to determine if Life ever evolved on Mars.

The 2016 and 2018 ExoMars probes were designed to look for evidence of life on Mars and set the stage for follow on missions to retrieve the first ever soil samples from the Red Planet’s surface and eventually land humans on Mars.

The proposed Mars budget cuts will obliterate these top priority science goals for NASA.

The BBC reports that “ a public announcement by NASA of its withdrawal from the ExoMars program will probably come once President Obama’s 2013 Federal Budget Request is submitted.”

A Feb. 9 article in ScienceInsider, a publication of the journal Science, states that “President Barack Obama will propose a $300 million cut in NASA’s planetary science programs as part of his 2013 request for the agency.”

This would amount to a 20% cut from $1.5 Billion in 2012 to $1.2 Billion in 2013. The bulk of that reduction is aimed squarely at purposefully eliminating the ExoMars program. And further deep cuts are planned in coming years !

The Mars budget of about $580 million this year would be radically reduced by over $200 million, thereby necessitating the end of NASA’s participation in ExoMars. These cuts will have a devastating impact on American scientists and engineers working on Mars missions.

The fallout from the looming science funding cuts also caused one longtime and top NASA manager to resign.

According to ScienceInsider, Ed Weiler, NASA’s science mission chief, says he “quit NASA Over Cuts to Mars Program.”

“The Mars program is one of the crown jewels of NASA,” said Ed Weiler to ScienceInsider.

“In what irrational, Homer Simpson world would we single it out for disproportionate cuts?”

“This is not about the science mission directorate, this is not even about NASA. This is about the country. We are the only country in the world that has demonstrated the capability to land anything on Mars. How can we allow that to be undermined?”

Weiler’s resignation from NASA on Sept. 30, 2011 was sudden and quick, virtually from one day to the next. And it came shortly after the successful launch of NASA’s GRAIL lunar probes, when I spoke to Weiler about Mars and NASA’s Planetary Science missions and the gloomy future outlook. Read my earlier Universe Today story about Weiler’s retirement.

Ed Weiler was the Associate Administrator for NASA’s Science Mission Directorate (SMD) and his distinguished career spanned almost 33 years.

The dire wrangling over NASA’s 2013 budget has been ongoing for many months and some of the funding reductions had already leaked out. For example NASA had already notified ESA that the US could not provide funding for the Atlas V launchers in 2016 and 2018. Furthermore, Weiler and other NASA managers told me the 2018 mission was de-scoped from two surface rovers down to just one to try and save the Mars mission program.

ESA is now inviting Russian participation to replace the total American pullout, which will devastate the future of Red Planet science in the US. American scientists and science instruments would be deleted from the 2016 and 2018 ExoMars missions.

The only approved US mission to Mars is the MAVEN orbiter due to blastoff in 2013 – and there are NO cameras aboard MAVEN.

Three Generations of US Mars Rovers - 4th Generation ExoMars rover to be Axed by NASA budget cuts.

NASA is caught in an inescapable squeeze between rising costs for ongoing and ambitious new missions and an extremely tough Federal budget environment with politicians of both political affiliations looking to cut what they can to rein in the deficit, no matter the consequences of “killing the goose that laid the golden egg”.

NASA Watch Editor Keith Cowing wrote; “Details of the FY 2013 NASA budget are starting to trickle out. One of the most prominent changes will be the substantial cut to planetary science at SMD [NASA’s Science Mission Directorate]. At the same time, the agency has to eat $1 billion in Webb telescope overruns – half of which will come out of SMD.”

The cost of the James Webb Space Telescope (JWST) has skyrocketed to $8.7 Billion.

To pay for JWST, NASA is being forced to gut the Mars program and other science missions funded by the same Science Mission Directorate that in the past and present has stirred the public with a mindboggling payoff of astounding science results from many missions that completely reshaped our concept of humankinds place in the Universe.

Meanwhile, China’s space program is rapidly expanding and employing more and more people. China’s scientific and technological prowess and patent applications are increasing and contributing to their fast growing economy as American breakthroughs and capabilities are diminishing.

Under the budget cutting scenario of no vision, the Curiosity Mars Science Laboratory rover will be America’s last Mars rover for a long, long time. Curiosity will thus be the third and last generation of US Mars rovers – 4th generation to be Axed !

Spirit Lander – 1st Color Image from Mars Orbit

[/caption]

The Lander platform for NASA’s Spirit rover has been photographed in stunning high resolution color for the first time from Mars orbit – just over 8 years after the now legendary robot survived the scorching atmospheric heat of the 6 minute plunge through the Martian atmosphere and bounced to a stop inside Gusev Crater on January 3, 2004.

Spirit’s three petaled landing pad was finally imaged in color by NASA’s powerful Mars Reconnaissance Orbiter (MRO) spacecraft just days ago on January 29, 2012 at 3:04 p.m. local Mars time.

The MRO spacecraft was soaring overhead and captured the image of Spirit’s lander with the high resolution HiRISE camera from a distance of some 262 kilometers, (162 miles).

“HiRISE has never before imaged the actual lander for the Spirit rover in color, [located] on the west side of Bonneville Crater,” writes Alfred McEwen, HiRISE Principal Investigator at the University of Arizona.

While protectively cocooned inside the airbag cushioned lander, Spirit bounced about two dozen times before rolling to rest on the Martian plains about ¼ mile away from Bonneville Crater. Then her landing petals unfurled, the airbags were partially retracted and Spirit eventually drove off the landing pad.

“The lander is still bright, but with a reddish color, probably due to a [Martian] dust cover.”

Spirit initially drove to Bonneville Crater and circumnavigated part way around the rim before speeding off towards the Columbia Hills, about 2 miles to the East. She eventually scaled the summit of Husband Hill and drove down the opposite side to the Home Plate” volcanic feature where she rests today – see travse map below.

“A bright spot from a remnant of the heat shield is still visible on the north rim of Bonneville Crater. The backshell and parachute are still bright, but were not captured in the narrow color swath.”

“The rover itself can still be seen near “Home Plate” in the Columbia Hills, but there is no obvious sign of rover tracks–erased by the wind,” McEwen notes.

Here is a photo taken by Spirit looking back to the lander – now imaged in color from orbit for the first time – for a comparative view, before she drove off forever.

Spirit endured for more than six years of bonus time exploration beyond her planned 90 day mission. And Opportunity is still roving Mars today !

Chinese scientists have assembled the highest resolution map ever created of the entire Moon and unveiled a series of global Moon images on Monday, Feb. 6.

The composite Lunar maps were created from over 700 individual images captured by China’s Chang’e-2 spacecraft and released by the country’s State Administration of Science, Technology and Industry for National Defence (SASTIND), according to reports from the state run Xinhua and CCTV new agencies.

“The map and images are the highest-resolution photos of the entirety of the Moon’s surface to be published thus far,” said Liu Dongkui, deputy chief commander of China’s lunar probe project, reports Xinhua.

Of course there are much higher resolution photos of numerous individual locations on the Moon taken from orbit by the spacecraft of other countries and from the surface by NASA’s Apollo lunar landing astronauts as well as unmanned Russian & American lunar landers and rovers.

Chang’e-2 is China’s second lunar probe and achieved orbit around our nearest neighbor in space in October 2010. It was launched on Oct. 1, 2010 and is named after a legendary Chinese moon goddess.

The images were snapped between October 2010 and May 2011 using a charge-coupled device (CCD) stereo camera as the spacecraft flew overhead in a highly elliptical orbit ranging from 15 km to 100 km altitude.

The Chang’e-2 maps have a resolution of 7 meters, which is 17 times greater than from China’s first lunar orbiter; Chang’e-1, launched in 2007.

In fact the maps are detailed enough that Chinese scientists were able to detect traces of the Apollo landers, said Yan Jun, chief application scientist for China’s lunar exploration project.


Chang’e-2 also captured high resolution photos of the “Sinus Iridum”area , or Bay of Rainbows, where China may land their next Moon mission. The camera had the ability to resolve features as small as 1 meter across at the lowest altitude.

The satellite left lunar orbit in June 2011 and is currently orbiting the moon’s second Lagrange Point (L2), located more than 1.5 million km away from Earth.

Chinese space program officials hope for a 2013 liftoff of the Chang’e-3 lunar rover, on what would be China’s first ever landing on another celestial body. China’s next step beyond the rover may be to attempt a lunar sample return mission in 2017.

Demonstrating the ability to successfully conduct an unmanned lunar landing is a key milestone that must be achieved before China can land astronauts on the Moon, perhaps within the next decade.

NASA’s twin GRAIL spacecraft recently achieved Lunar orbit over the New Year’s weekend. The duo of probes were just renamed as “Ebb and Flow” – the winning entries in an essay naming contest submitted by 4th Grade US students from Bozeman, Montana.

At this time NASA does not have the funding or an approved robotic lunar landing mission, due to severe budget cuts.And even worse NASA cuts will be announced shortly !

Russia hopes to send the Lunar Glob spacecraft to land on the Moon around 2015.

Since the United States has unilaterally scuttled its plans to return American astronauts to the Moon’s surface, it’s very possible that the next flag planted on the Moon by humans will be Chinese.

The giant Asteroid Vesta literally floats in space in a new high resolution 3-D image of the battered bodies Eastern Hemisphere taken by NASA’s Dawn Asteroid Orbiter.

Haul out your red-cyan 3-D anaglyph glasses and lets go whirling around Vesta and sledding down mountains to greet the alien Snowman! The sights are fabulous !

The Dawn imaging group based at the German Aerospace Center (DLR), in Berlin, Germany and led by team member Ralf Jaumann has released a trio of new high resolution 3-D images that are the most vivid anaglyphs yet published by the international science team.

The lead anaglyph shows the highly varied topography of the Eastern Hemisphere of Vesta and was taken during the final approach phase as Dawn was about 5,200 kilometers (3,200 miles) away and preparing to achieve orbit in July 2011.

The heavily cratered northern region is at top and is only partially illuminated because of Vesta’s tilted angle to the Sun at that time of year. Younger craters are overlain onto many older and more degraded craters. The equatorial region is dominated by the mysterious troughs which encircle most of Vesta and may have formed as a result of a gargantuan gong, eons ago.

The southern hemisphere exhibits fewer craters than in the northern hemisphere. Look closely at the bottom left and you’ll see the huge central mountain complex of the Rheasilvia impact basin visibly protruding out from Vesta’s south polar region.

This next 3-D image shows a close-up of the South Pole Mountain at the center of the Rheasilvia Impact basin otherwise known as the “Mount Everest of Vesta”.

The central complex is approximately 200 kilometers (120 miles) in diameter and is approximately 20 kilometers (12 miles) tall and is therefore about two and a half times taller than Earth’s Mount Everest!

Be sure to take a long look inside the deep craters and hummocky terrain surrounding “Mount Everest”.

A recent study concludes that, in theory, Vesta’s interior is cold enough for water ice to lurk beneath the North and South poles.

Finally lets gaze at the trio of craters that make up the “Snowman” in the 3-D image snapped in August 2011 as Dawn was orbiting at about 2,700 kilometers (1,700 miles) altitude. The three craters are named Minucia, Marcia and Calpurnia from top to bottom. Their diameters respectively are; 24 kilometers (15 miles), 53 kilometers (33 miles) and 63 kilometers (40 miles).

It is likely that Marcia and Calpurnia formed from the impact of a binary asteroid and that Minucia formed in a later impact. The smooth region around the craters is the ejecta blanket.

Vesta is the second most massive asteroid in the main Asteroid Belt between Mars and Jupiter. It is 330 miles (530 km) in diameter.

Dawn is the first spacecraft from Earth to visit Vesta. It achieved orbit in July 2011 for a year long mission. Dawn will fire up its ion propulsion thrusters in July 2012 to spiral out of orbit and sail to Ceres, the biggest asteroid of them all !

Vesta and Ceres are also considered to be protoplanets.

SpaceX Test Fires SuperDraco Abort Engines Critical To Astronaut Launch Safety

Space Exploration Technologies (SpaceX) has test fired a prototype of its new SuperDraco engine that will be critical to saving the lives of astronauts flying aboard a manned Dragon spacecraft soaring to orbit in the event of an in-flight emergency.

The successful full-duration, full-thrust firing of the new SuperDraco engine prototype was completed at the company’s Rocket Development Facility in McGregor, Texas. The SuperDraco is a key component of the launch abort system of the Dragon spacecraft that must fire in a split second to insure crew safety during launch and the entire ascent to orbit.

The Dragon spacecraft is SpaceX’s entry into NASA’s commercial crew development program – known as CCDEV2 – that seeks to develop a commercial ‘space taxi’ to launch human crews to low Earth orbit and the International Space Station (ISS).

The engine fired for 5 seconds during the test, which is the same length of time the engines need to burn during an actual emergency abort to safely thrust the astronauts away.

Watch the SpaceX SuperDraco Engine Test Video:

Nine months ago NASA awarded $75 million to SpaceX to design and test the Dragon’s launch abort system . The SuperDraco firing was the ninth of ten milestones that are to be completed by SpaceX by around May 2012 and that were stipulated and funded by a Space Act Agreement (SAA) with NASA’s Commercial Crew Program (CCP).

“SpaceX and all our industry partners are being extremely innovative in their approaches to developing commercial transportation capabilities,” said Commercial Crew Program Manager Ed Mango in a NASA statement. “We are happy that our investment in SpaceX was met with success in the firing of its new engine.”

Dragon will launch atop the Falcon 9 rocket, also developed by SpaceX.

“Eight SuperDracos will be built into the sidewalls of the Dragon spacecraft, producing up to 120,000 pounds of axial thrust to quickly carry astronauts to safety should an emergency occur during launch,” said Elon Musk, SpaceX chief executive officer and chief technology officer in a statement. “Those engines will have the ability to deep throttle, providing astronauts with precise control and enormous power.”

“Crews will have the unprecedented ability to escape from danger at any point during the launch because the launch abort engines are integrated into the side walls of the vehicle,” Musk said. “With eight SuperDracos, if any one engine fails the abort still can be carried out successfully.”

SpaceX is one of four commercial firms working to develop a new human rated spacecraft with NASA funding. The other firms vying for a commercial crew contract are Boeing, Sierra Nevada and Blue Origin.

“SuperDraco engines represent the best of cutting edge technology,” says Musk. “These engines will power a revolutionarylaunch escape system that will make Dragon the safest spacecraft in history and enable it to land propulsively on Earth or another planet with pinpoint accuracy.”

The privately developed space taxi’s will eventually revive the capability to ferry American astronauts to and from the ISS that was totally lost when NASA’s Space Shuttle orbiters were forcibly retired before a replacement crew vehicle was ready to launch.

Because the US Congress slashed NASA’s commercial crew development funding by more than 50% -over $400 million – the first launch of a commercial space taxi is likely to be delayed several more years to about 2017. Until that time, all American astronauts must hitch a ride to the ISS aboard Russian Soyuz capsules.

This week the Russian manned space program suffered the latest in a string of failures when when technicians performing a crucial test mistakenly over pressurized and damaged the descent module of the next manned Soyuz vehicle set to fly to the ISS in late March, thereby forcing about a 45 day delay to the launch of the next manned Soyuz from Kazakhstan.
