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.
Vega's first launch, dubbed VV01, occurred on Feb 13, 2012 from Europe's Spaceport in Kourou, French Guiana. It carried nine satellites into orbit: LARES, ALMASat-1 and seven Cubesats.

HuartESA 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.

I spy Phoenix! said the HiRISE camera on board the Mars Reconnaissance Orbiter! This new image acquired on January 26, 2012 shows that the Phoenix lander and its backshell are still visible from Mars’ orbit. The parachute, seen in earlier images, is probably about 130 meters south of where this picture ends. This is one of a series of images to monitor frost patterns at the Phoenix landing site, said HiRISE Principal Investigator, Alfred McEwen, adding that this new images shows almost the same appearance of the hardware as 1 Mars years ago, in 2010. See larger versions of this image at the HiRISE website.
See below for comparison images from orbit from 2008, shortly after Phoenix landed and 2010, after the mission had ended.
Two images of the Phoenix Mars lander taken from Martian orbit in 2008 and 2010. The 2008 lander image shows two relatively blue spots on either side corresponding to the spacecraft's clean circular solar panels. In the 2010 image scientists see a dark shadow that could be the lander body and eastern solar panel, but no shadow from the western solar panel. Image credit: NASA/JPL-Caltech/University of Arizona
In these images, also from the Mars Reconnaissance Orbiter, signs of severe ice damage to the lander’s solar panels show up in the 2010 image, with one panel appearing to be completely gone. The Phoenix team says this is consistent with predictions of how Phoenix could be damaged by harsh winter conditions. It was anticipated that the weight of a carbon-dioxide ice buildup could bend or break the solar panels.

One solitary boulder on the Moon apparently decided to take a little journey. The Lunar Reconnaissance Orbiter Camera captured the track of a bouncing, rolling 9-meter boulder that used to sit along the rim of a crater. From the pristine nature of the tracks, it might seem that the rock may have taken its trip just recently. But with the high resolution capability of the LROC, scientists can see that a few tiny craters are superimposed among the track and therefore post-date the time the boulder traveled. Scientists estimate this track was created 50-100 million years ago.
“Though long ago to humans, however, this boulder’s journey was made in geologically recent times,” wrote lunar scientist James Ashley on the LROC website. “Studies suggest that regolith development from micrometeorite impacts will erase tracks like these over time intervals of tens of millions of years…Eventually its track will be erased completely.”
What might have caused the rock to roll so recently? Ashley said perhaps this boulder was sent on its way by ground-shaking caused by the violence of a nearby impact. Perhaps a direct hit by a small meteoroid did the job.
This isn’t the first time LRO has captured evidence of “moving” rocks. See our previous article about several other images of bouncing boulders.

A mission which helped map the ultraviolet sky and worked to confirm the nature of dark energy is coming to an end. Galaxy Evolution Explorer, or GALEX, was placed in standby mode today after nearly nine years of service and will be decommissioned later this year. With data from the mission, scientists were able to catalog millions of galaxies spanning 10 billion years of cosmic time.
The Galaxy Evolution Explorer launched in April of 2003 on board a Pegasus XL rocket. It completed its prime mission in the fall of 2007, but the mission was extended to continue its census of stars and galaxies. The variable star Mira. Image credit: Galex
Other mission highlights include the discovery of a gigantic comet-like tail behind a speeding star, finding rings of new stars around old galaxies, exploring “teenager” galaxies, which help to explain how galaxies evolve, and catching a black hole devouring a star.
The mission was part of NASA’s Explorer’s program and was built and managed by the Jet Propulsion Laboratory. Scientists from around the world participated in GALEX studies.
Please take the time to respectfully recognize the passing of veteran astronaut, Janice Voss. She was a former science director for a NASA exoplanet-hunting spacecraft and also a member of five manned spaceflights. She lost her battle with cancer today at the young age of 55. “Just got the very sad news that U.S. astronaut Janice Voss passed away last night,” the Association of Space Explorers, an international organization representing more than 350 individuals who have flown in space, wrote on Facebook. “Our thoughts go out to her family and friends.” NASA confirmed Voss’ passing in a statement issued on Tuesday (Feb. 7), saying she had passed away overnight.
Janice was born on October 8, 1956, in South Bend, Indiana, but she called Rockford, Illinois home. Some of her passions for life included flying, volleyball, dancing and reading science fiction. She graduated from from Minnechaug Regional High School, Wilbraham, Massachusetts, in 1972, continued on to Purdue University for her bachelor of science degree and achieved a master of science degree in electrical engineering and a doctorate in aeronautics/astronautics from the Massachusetts Institute of Technology in 1977 and 1987, respectively. From there, Janice continued her education by taking some correspondence courses from the University of Oklahoma and did some graduate work in space physics at Rice University in 1977 and 1978.
Astronaut Janice Voss pictured in 2000 on the flight deck of the space shuttle Endeavour during the STS-99 mission. (NASA)In 1990, Janice Voss was chosen by NASA for the astronaut corps and served as a mission specialist on five space shuttle missions, including the only repeat flight in the program’s 30 year history. But that’s not all. She also flew with the first commercial lab, rendezvoused with Russia’s Mir space station and helped create the most complete digital topographic map of the Earth. In June 1993, Janice took part in biomedical and material science experiments as a member of the Spacehab module – a commercial laboratory attached to the orbiter’s payload bay. In February 2000, Voss again launched on Endeavour as part of the Shuttle Radar Topography Mission crew. After deploying a nearly 200-foot (60-meter) mast, Voss and her team labored through two full shifts to map more than 47 million square miles (122 million square kilometers) of the Earth’s land surface. The shuttle Endeavour served as both her first and final mission.
The first time a space shuttle came close to the Russian Space Station, Mir, Dr. Voss was there. As her second mission, she and her STS-63 crew mates met with the Russians to discuss flight techniques, communications, sensors aids and navigation. The February 1995 “Near-Mir” mission set the stage for the first shuttle-Mir docking later that year. Janice also served on another historic mission – the only time a crew was launched twice to perform the same mission. The first launch came on April 4, 1997 and three days later it returned to Earth after a fuel cell problem. Ninty days later, the Columbia was restored and it launched again into a successful 15 day flight. This time Voss and crew engaged their time inside a European Spacelab module, conducting experiments as part of the Microgravity Science Laboratory (MSL) mission.

(NASA)Over her career, astronaut Janice Voss totaled over 49 days in space, traveling 18.8 million miles (30.3 million km) while circling the Earth 779 times. Her five missions tied her with the record for the most spaceflights by a woman. When she at last touched down on Earth, she went on to the Johnson Space Center in Houston, Texas to NASA’s Ames Research Center at Moffett Field, California, where she headed the science program for the agency’s Kepler space observatory. She stayed at Ames until 2007 and spent the rest of her time as the payload lead in the astronaut office’s space station branch at the Johnson Space Center.
Janice Voss, pictured looking over a checklist on space shuttle Endeavour's aft flight deck during her final spaceflight. (NASA)“As payload commander of two shuttle missions, Janice was responsible for paving the way for experiments that we now perform on a daily basis on the International Space Station,” chief astronaut Peggy Whitson said in a statement. “By improving the way scientists are able to analyze their data, and establishing the experimental methods and hardware necessary to perform these unique experiments, Janice and her crew ensured that our space station would be the site of discoveries that we haven’t even imagined.”
“During the last few years, Janice continued to lead our office’s efforts to provide the best possible procedures to crews operating experiments on the station today,” she said. “Even more than Janice’s professional contributions, we will miss her positive outlook on the world and her determination to make all things better.”

This is why I always keep a pair of 3-D glasses by my computer. This well-preserved crater on Mars may look like just your average, run-of-the-mill impact crater in 2-D, but in 3-D, the sharply raised rim, the deep, cavernous crater body, and especially the steep crater walls will have you grabbing your armchairs so you don’t fall in. The image is courtesy of the HiRISE camera team from the Mars Reconnaissance Orbiter. This unnamed crater is about 6 or 7 kilometers wide from rim to rim. HiRISE took the image on New Year’s Eve 2011.
HiRISE principal investigator Alfred McEwen says that the camera has imaged hundreds of well-preserved impact craters on Mars ranging from 1 meter to more than 100 kilometers wide. What can the scientists learn from craters?
“These targets are of great interest for multiple reasons,” he said. “First, we want to better understand impact cratering, a fundamental surface process. Second, such craters often contain good exposures of bedrock in the steep walls and, if the crater is large enough, in the central uplift. Just like terrestrial geologists are attracted to good bedrock outcrops like road cuts, planetary geologists are attracted to well-preserved craters.
“Third, the steep slopes often reveal active processes, such as formation of gullies, boulder falls, and slope streaks that could form in a variety of ways. Some of these active processes could be related to water, since the crater may expose lenses of ice or salty water, or create deep shadows that trap volatiles, or expose salts that can extract water from the air.”
Plus, they are just plain wonderful to behold, especially in the resolution the HiRISE can obtain.

The Rosetta mission will do something never before attempted: land on a comet. The spacecraft is now on its way to intercept comet 67P/Churyumov-Gerasimenko in January 2014 and land a probe on it for what promises to be an amazing view. But what we know of comets so far comes from a few flyby missions. So, with surface composition and conditions largely a mystery, so how did engineers prepare to land on something that could be either solid ice or rock, or a powdery snow or regolith – or something in between?
They had to design the Philae lander so it could land equally well on any surface. In the tiny gravitational field of a comet, landing on hard icy surface might cause Philae to bounce off again. Alternatively, hitting a soft snowy one could result in it sinking. To cope with either possibility, Philae will touch as softly as possible. In fact, engineers have likened it more to docking in space.
Philae will fire harpoons to secure itself to the comet; additionally, the landing gear is equipped with large pads to spread its weight across a broad area (kind of like snowshoes.)
While landing on a comet will certainly be nail-biting, having a front row seat for when the comet gets closer to the Sun is the most highly anticipated part of the mission.
[/caption]
“In some ways, a flyby is just a tantalizing glimpse of a comet at one stage in its evolution,” says Claudia Alexander, project scientist for the U.S. Rosetta Project at JPL. “Rosetta is different. It will orbit 67P for 17 months. We’ll see this comet evolve right before our eyes as we accompany it toward the Sun and back out again.”
We’ll be able to watch as it becomes “something poetic and beautiful, trailing a vast tail,” said Alexander. For once, we’ll be able to watch the surface of a comet transform in front of our eyes instead of relying on artist concept drawings! Additionally, the Rosetta spacecraft up above will be busy mapping the comet’s surface and magnetic field, monitoring the comet’s erupting jets and geysers, measuring outflow rates, and much more. Together, the orbiter and lander will build up the first 3-D picture of the layers and pockets under the surface of a comet.
Comets are considered a gold mine for astronomers who want to know what conditions were like back in the early days of our Solar System. And the data and images from this mission promises to be some of the most stunning we’ve yet seen.

Planet hunter extraordinaire Geoff Marcy recently let his frustration surface about the current state of the search for other habitable solar systems. Despite the phenomenal planet-finding success of NASA’s Kepler mission, Marcy, an astronomer at the University of California at Berkeley, correctly pointed out that NASA budget cuts have severely hampered the hunt for extrasolar life.
A decade ago, only a few dozen extrasolar planets had been detected. Today, by some recent gravitational microlensing estimates, there are more planets than stars in the Milky Way. But without the ability to characterize these extrasolar planetary atmospheres from space, we are astrobiologically hamstrung.
NASA’s goal had been that by 2020, we would have a pretty good idea about how frequently terrestrial Earth-mass planets orbit other stars — whether those planets have atmospheres that resemble our own; and, more crucially, whether those atmospheres exhibit the telltale signs of planets harboring life.
But consider how the federal government spends our tax dollars on a daily basis. Each and every day for more than a decade, the U.S. military spent roughly $1 billion a day funding congressionally-undeclared wars in Iraq and Afghanistan.
In contrast, NASA’s cancelled SIM and TPF missions were both originally estimated to have cost less than $1.5 billion dollars each.

SIM, the Space Interferometry Mission, was to have focused on finding extrasolar earths in a targeted search; its follow-on mission, NASA’s TPF, the Terrestrial Planet Finder mission, was to have characterized the atmospheres of these earth twins in an attempt to remotely detect the signatures of life.
The astronomical community continues to be resourceful as it can in working around these problems. But if NASA had followed through with the SIM and TPF missions in the timeframe that it first announced, we would have a very good idea of our own earth’s galactic pecking order by now.
Instead, war-funding has taken priority. On the home front, we’ve let the attacks of 9/11 take us down a road that has resulted in our airports resembling Orwellian netherworlds. Most of us now accept that we must basically disrobe and be physically prodded before boarding an aircraft.
Kids born at the beginning of what was supposed to be a great new millennium — remember 2001: A Space Odyssey, anyone? — have instead grown up accustomed to running the gauntlet just to take their teddy bears onto the plane with them.
Contrast the country’s current poisoned national mood with the heady days of euphoria surrounding this country’s Moon shots.
Dare we attempt to again turn at least a portion of our swords back into ploughshares?
If the U.S. is going to continue to lead the world in science and technology, the country will have to quit living in a state of perpetual geopolitical paranoia and take space seriously again.
No one wants to turn a blind eye to our national defense and NASA may never return to its glory days. But something is amiss when within a generation, we’ve gone from John F. Kennedy pointedly challenging the nation to test its mettle by safely sending a man to the moon and back before the end of the decade to this current era of national teeth gnashing.
Newt Gingrich was openly ridiculed on the morning TV news shows for advocating that the U.S. use private enterprise to help us put a manned lunar colony on the moon. Mitt Romney responded that he’d fire any employee that walked into his office and suggested such a plan.
Perhaps Gingrich is not the ideal messenger for jumpstarting a long dormant manned lunar program. But our country has reached a sad nadir when a presidential candidate is publicly mocked for advocating the hard work of boldly revamping our national space policy.
NASA's Interstellar Boundary Explorer (IBEX) has found that there's more oxygen in our solar system than there is in the nearby interstellar material. That suggests that either the sun formed in a different part of the galaxy or that outside our solar system life-giving oxygen lies trapped in dust or ice grains unable to move freely in space.

[/caption]
If we could board the starship Enterprise-D and were able to look through Giordi LaForge’s visor we might be able to see the interstellar medium – the ‘stuff’ between the stars — as wispy clouds of oxygen, hydrogen, helium and neon. Instead, since we are back in the 21st century, we have the Interstellar Boundary Explorer (IBEX) spacecraft, which has now made the first–ever direct observations of neutral hydrogen and oxygen atoms drifting into our solar system from the region outside our heliosphere. Surprisingly, this material is more ‘alien’ than scientists were expecting, as the matter in the galactic wind doesn’t contain the same exact material as what our solar system is made of.
The most important finding is there is less oxygen ‘out there.’ For every 20 neon atoms in the galactic wind, there are 74 oxygen atoms. In our own solar system, however, for every 20 neon atoms there are 111 oxygen atoms. That translates to more oxygen in any given region of the solar system than in the local interstellar space.
“Our solar system is different than the space right outside it and that suggests two possibilities,” said David McComas the principal investigator for IBEX. “Either the solar system evolved in a separate, more oxygen-rich part of the galaxy than where we currently reside or a great deal of critical, life-giving oxygen lies trapped in interstellar dust grains or ices, unable to move freely throughout space.”
Either way, the scientists said, this affects scientific models of how our solar system – and life – formed. And more than just helping to determine the distribution of elements in the interstellar medium, these new measurements provide clues about how and where our solar system formed, the forces that physically shape our solar system, and even the history of other stars in the Milky Way.
“This alien interstellar material is really the stuff that stars and planets and people are made of — and it’s very important to be measuring it directly,” McComas said during a press briefing on Tuesday.
If Spock were a member of this mission, he would probably raise an eyebrow and say, “Fascinating.”*
Our heliosphere is the region of space dominated by the Sun and is inflated, like a bubble, in local interstellar material by the million mile-per-hour solar wind. This bubble keeps out the ionized or charged particles and magnetic fields from the galaxy and so protects us from dangerous Galactic Cosmic Rays. Credit: SwRI
Interstellar clouds hold the elements of exploded supernovae, which are dispersed throughout the galaxy. As the interstellar wind blows these charged and neutral particles through the Milky Way, the spacecraft can measure samples that make it into our solar system. IBEX scans the entire sky once a year, and every February, its instruments point in the correct direction to intercept incoming neutral atoms. IBEX counted those atoms in 2009 and 2010 and has now captured the best and most complete glimpse of the material that lies so far outside our own system.
In addition to sampling the raw “star stuff,” the findings are important because the interstellar gas surrounding us can affect the strength of the Sun’s heliosphere – the area of influence by the Sun, and like a shielding bubble, protects us from dangerous galactic cosmic rays, the majority of which would come into the inner solar system if not for this bubble.
IBEX also discovered that the interstellar wind is approximately 7,000 miles per hour slower than previously thought. This indicates that our solar system is still in what’s referred to as the “local interstellar cloud.” However, the scientists noted that we will transition into a different region at any time within a few thousand years (very short on astronomical time scales) where conditions will change and affect the heliosphere’s protective capability. And no one knows if that change will be for the better or worse.
As our solar system travels around the Milky Way through the vast sweep of cosmic time, the ever-changing nature of the heliosphere has likely had implications on the evolution of life on Earth as varying levels of radiation spurred genetic mutations and, perhaps, wholesale extinctions.
“This is all very exciting, and it has important implications as the Sun moves through space and in and out of interstellar clouds , the flux of galactic cosmic rays varies,” said Priscilla Frisch, senior scientist, Department of Astronomy and Astrophysics at the University of Chicago, and part of the IBEX mission. “And that is recorded in the geo-isotopic records. Someday maybe we can link the Sun’s motion through interstellar clouds with geological records on Earth, and trace the geological history of Earth.”
The conditions necessary to make the heliosphere, namely the balance of an outward pushing stellar wind and the inward compression of surrounding interstellar gas is so common, that perhaps most stars have analogous structures, called astrospheres. Photographs of three such astrospheres are shown, as taken by various telescopes. Credit: NASA/ESA/JPL-Caltech/Goddard/SwRI
Additionally, while the new findings provide a greater understanding of our heliosphere, it will also aid scientists in exploring analogous structures called “astrospheres,” surrounding other stars throughout the galaxy.
“We know at least two cases of another star with a planetary system and an astrosphere around it, and these are the true analogs to our own solar system,” said Seth Redfield, assistant professor, Astronomy Department, Wesleyan University, in Middletown, Connecticut, also speaking at the press briefing. “The discovery of other planets coupled with our understanding of the impact these galactic cosmic rays could potentially have on planets and the emergence and evolution of life. These are connections that we haven’t explored fully, and with these new findings from IBEX, are now coming together to a very interesting topic to explore.”

IBEX is a small spacecraft, roughly the size of a card table, and is one of NASA’s low-cost missions. It is in Earth orbit, but can observe the edges of the solar system with detectors that “look” outward and collect particles called energetic neutral atoms. With data from IBEX, scientists are creating the first map of the boundary of our solar system.
These latest findings from IBEX were presented in a series of science papers appearing in the Astrophysics Journal on January 31, 2012.
“This set of papers provide many of the first direct measurements of the interstellar medium around us,” says McComas. “We’ve been trying to understand our galaxy for a long time, and with all of these observations together, we are taking a major step forward in knowing what the local part of the galaxy is like.”
