Assembled from 29 raw images taken by the Cassini orbiter on Monday, April 25, this animation brings us along an orbital ride with Rhea as it crosses Saturn’s nighttime face, the planet’s shadow cast across the ringplane. Sister moons Dione and Tethys travel the opposite lane in the background, eventually appearing to sink into Saturn’s atmosphere.

The exposure varies slightly from frame to frame due to the fact that they are not all taken with the same color channel filter.
Rhea (1,528 kilometers, or 949 miles, wide), Dione (1,123 kilometers, or 698 miles wide) and Tethys (1,066 kilometers, or 662 miles wide) are all very similar in composition and appearance. The moons are composed mostly of water ice and rock, each covered in craters of all sizes and crisscrossed by gouges, scarps and chasms. All three are tidally locked with Saturn, showing the same face to their parent planet in the same way that the Moon does with Earth.
The Cassini spacecraft was 2,227,878 km (1,384,339 miles) from Rhea when the images were taken.

KENNEDY SPACE CENTER – A large brush fire suddenly broke out this today (April 27) less than 1 mile fom the Kennedy Space Center (KSC) Press Site in the midst of the countdown to Space Shuttle Endeavour’s last launch, set for this Friday, April 29.
Huge plumes of billowing smoke were sent skyward over the spaceport starting around 1 p.m. from the fires and were spread out over more than 100 acres. The fires erupted at some distance behind the NASA Tweeters tent erected at the press site and were located just 3 miles from the shuttle launch pad. The cause of the fires is unknown but occurred after a long spell of dry weather at KSC.

Helicopters and NASA Firefighters were called in to put out the fires. Fire trucks careened past the countdown clock towards the nearby fire. The helicopters flew back and forth all afternoon dumping buckets of seawater onto the wildfires trying to bring it under control.
“The shuttle launch pad was never in any danger due to the Turn basin in between and it hasn’t impacted any launch operations,” KSC spokesman Allard Beutel told Universe Today.
The Universe Today team of Alan Walters and Ken Kremer witnessed the spectacular and potentially frightening scene first hand and onsite.
It looked like Armageddon all afternoon long and was finally contained tonight. Nothing like this ever occurred so close to a launch and its not clear if the fire would have caused a scrub on launch day. Check out our up close photo album.

KENNEDY SPACE CENTER – The six man crew for Shuttle Endeavour’s final flight to space arrived today (April 26) at the Kennedy Space Center in Florida. The crew flew in to the Shuttle Landing Facility (SLF) on a quartet of T-38 jets from their training base in Houston.
Shuttle Commander Mark Kelly introduced his crew to a large crowd of gathered reporters, photographers and NASA officials including Launch Director Mike Leinbach, KSC Director Bob Cabana and Kelly’s twin brother Scott who recently returned from a six month stint aboard the International Space Station.

Speaking on behalf of the entire crew he said, “We’re really happy to be here today,” said Kelly. “We got a chance to take look at the orbiter as we first flew over the field and then the over pad. It’s great to see Endeavour all ready to go again.”
Kelly was exuberant in saying that his wife, Congresswoman Gabrielle Giffords, was well enough to attend the STS-134 launch set for Friday, at 3:47 p.m. EDT.
The shuttle launch countdown officially commenced at 2 PM today. The weather outlook is 80% GO, with a 20% chance of weather violations prohibiting launch according to Shuttle weather officer Kathy Winters.

STS-134 is the 25th and final launch of Space Shuttle Endeavour.
The primary payload aboard Endeavour is the $2 Billion Alpha Magnetic Spectrometer (AMS) ) which the crew will attach to the International Space Station. The AMS will collect cosmic rays, search for dark energy, dark matter and anti matter and seeks to determine the origin of the Universe.

Pitted "swiss cheese" terrain at Mars' south pole hints at sublimation of underground CO2
[/caption]
Scientists have spotted an underground reservoir near Mars’ south pole the size of Lake Superior… except that this lake is filled with frozen carbon dioxide – a.k.a. “dry ice”!
A recent report by scientists at the Southwest Research Institute in Boulder, CO reveals variations in Mars’ axial tilt can change how much carbon dioxide gets released into the atmosphere, affecting factors from the stability of water on its surface to the power and frequency of dust storms.
Thickness Map of Buried CO2 Ice Deposit
The Mars Reconnaissance Orbiter’s ground-penetrating Shallow Radar identified a subsurface deposit of frozen material, confirmed as carbon dioxide ice by its radar signature and visual correlation to the surface pitting seen above. As the polar surface warms during the Martian spring, underground CO2 deposits evaporate (or “sublime”) leaving behind round depressions in the frozen ground. (This has been aptly dubbed “swiss cheese terrain” by researchers on the HiRISE imaging team.)
While scientists were aware of seasonal CO2 ice layers atop the water ice this new discovery brings to light nearly 30 times more frozen CO2 than was previously believed to exist. In fact this particular deposit alone contains 80% the amount of CO2 currently present in the planet’s entire atmosphere.
The importance of this finding is how the carbon dioxide ultimately affects the global Martian climate as it freezes and thaws. When the CO2 is frozen and locked away in subsurface deposits like this, it’s not free to enter the atmosphere and do what CO2 does best: warm the planet… as well as increase atmospheric pressure. This means that liquid water cannot last as readily on the surface since it will either freeze or boil away. Also with less air pressure the strength of wind is decreased, so dust storms are less frequent and less severe.
When factored in with the axial tilt difference – and thus variations in the amount of sunlight hitting the poles – researchers’ models show that Mars’ average atmospheric pressure may at times be 75% higher than it is today.
These shifts in the orientation of the Red Planet’s axis occur on 100,000-year intervals… long by human standards but geologically very frequent. Mars may have had liquid water existing on its surface fairly recently!

Although this may sound that Mars has had its own share of global warming due to CO2 emissions in its history, it must be remembered that Mars and Earth have very different atmospheric compositions. Earth’s atmosphere is much thicker and denser than Mars’, so even when doubling its CO2 content Mars’ atmosphere is still too thin and dry to create a strong greenhouse effect… especially considering that the polar caps on Mars increase cooling more than additional CO2 in the atmosphere raises global temperature. Without oceans and atmosphere to collect and distribute heat, the effect of any warming quickly radiates out into space…and eventually the planet swings back into a freeze-dried state.
“Unlike Earth, which has a thick, moist atmosphere that produces a strong greenhouse effect, Mars’ atmosphere is too thin and dry to produce as strong a greenhouse effect as Earth’s, even when you double its carbon-dioxide content.”

KENNEDY SPACE CENTER – Despite utilizing just half the work force originally planned and cutting back further on the original test program, Lockheed Martin is now accelerating the Orion Multi-Purpose Crew Vehicle (MPCV) launch schedule and aiming to achieve an Earth orbital flight by 2013 and a human crewed flight as early as 2016. The first Orion crew cabin has been built and construction of the second spacecraft has begun.
What’s more is that a bold “manned mission beyond low Earth orbit and even a lunar fly by is possible in 2016 if NASA’s new heavy lift rocket is developed in time,” says John Karas, vice president of Lockheed Martin’s Human Space Flight programs, in an exclusive interview with Universe Today. A bipartisan majority in Congress recently approved funding for the Heavy lift booster and mandated that the first flight occur in 2016.
“In order to go to the moon, we need NASA’s new heavy lifter,” Karas explained. Orion was designed with the capability to fly human crews to low Earth orbit (LEO) and the International Space Station, as well as beyond to deep space, the Moon, Asteroids, Lagrange Points and Mars.
Lockheed Martin is the prime contractor for Orion under a multi-year contract awarded by NASA in 2006.

Karas told me that the streamlined test program would involve flying one Orion mission per year – of increasing complexity – from 2013 to 2016. “Lockheed Martin is working with NASA to determine what are the right launch vehicles and the right missions.”
American astronauts could return to the moon in 5 years after a more than 40 year long hiatus.

“Right now we are building a brand new crew cabin for the first Orion mission; OFT-1. But everything depends on the budget.”
“For the inaugural Orion test flight in 2013 NASA is considering a Delta IV Heavy booster rocket,” Karas said. “The Atlas V is not powerful enough to send the whole 50,000 pound spacecraft into orbit. With an Atlas we could only launch an Orion crew module. You would have to have delete the Service Module (SM) and /or other subsystems.”
“Orion would be lofted some 7,000 miles out, and then sent back for Earth reentry to simulate something close to lunar velocity, around 80% or so. So we would definitely be testing the deep space environment. Therefore the test flight would be a lot more involved than just a simple Earth orbital reentry.
“For the first Orion mission, we will put as much capability on it as possible depending on the budget,” Karas amplified. “But it’s unlikely to have solar arrays without a few hundred million more bucks. The capability is money limited.”
“The 2014 flight could be a high altitude abort test or perhaps something else.”
“Then a full up unmanned test flight would follow in 2015,” Karas explained.
“If we have a heavy lifter, the 2016 flight with the first human crew could be a deep space mission or a lunar fly by lasting more than a week.”

Lockheed has already constructed the initial Orion crew vehicle – known as the first article or Ground Test Article (GTA). The Orion GTA first article was built at NASA’s Michoud Assembly Facility (MAF) in New Orleans, LA where I inspected it after the structural framework was welded into one piece.
Following the installation of mass and volume simulators and a successful series of pressure tests, the first article was then shipped in February this year to the company’s new state-of-the-art Space Operation Simulation Center (SOSC) located in Denver, Colorado.
“At Denver, we are going to finish the assembly of the first article by July of this year so it looks like a spacecraft – adding the doors, windows, thermal tiles and more,” Karas said. “Then it undergoes rigorous acoustics tests until September – known as Shake and Bake – to simulate all aspects of the harsh environment of deep space.”
The next step after that was to send it to NASA Langley for intensive water drop landing tests. But that plan may well change Karas told me.
“The first article – or GTA – is flight worthy. So we don’t want to break the spacecraft during the water landing tests. In the newly revised plan it may be used on the 2nd Orion flight in 2014 instead of reserving it for ground tests only. It would fly with a service module, but not solar panels. The first article could even be the first flight vehicle if the program funding is insufficient.”

“We have only half the budget for Orion that was planned earlier by NASA,” Karas stated.
“1500 less people are working on Orion since 1 year ago from the start to the end of 2010 – and that number includes all the subcontractors. We had to lay off a lot of people, including some folks we intended to hire.”
“MAF is now focused on building the composite structures of the first Service Module with about 200 people. That’s about half of what should have been about 400 folks. The earlier work at Michoud (MAF) focused on the metallic structures of the cabin for the first article,” said Karas.
To a large degree, launching astronauts to deep space is more a matter of sheer political will power then solving technical issues. And it all comes down to the bucks.
If NASA’s Heavy lifter is not available an alternative scenario with other expendable rockets would have to be developed to achieve the escape velocity required to send a crew of astronauts to the Moon.
Lockheed Martin has independently proposed a stepping stone approach that would send astronauts in Orion spacecraft to challenging deep space targets such as the Moon, and elsewhere such as Asteroids, Lagrange points and Mars that have never been done before and which I’ll feature in upcoming articles.
“Exploration missions that are affordable and sustainable will inevitably lead to technological innovation, to scientific discovery, and to public inspiration and spark an interest in STEM careers that can help the United States counter the overwhelming numerical disadvantage in college graduates it faces in these disciplines in developing third-world nations,’ says Karas.

Ah, Pluto. Seems every time we think we’ve got it figured out, it has a new surprise to throw at us.
First spotted in 1930 by a young Clyde Tombaugh, for 76 years it enjoyed a comfortable position as the solar system’s most distant planet. Then a controversial decision in 2006 by the International Astronomical Union, spurred by suggestions from astronomer (and self-confessed “planet-killer”) Mike Brown*, relegated Pluto to a new class of worlds called “dwarf planets”. Not quite planets and not quite asteroids, dwarf planets cannot entirely clear their orbital path with their own gravitational force and thus miss out on full planetary status. Besides immediately making a lot of science textbooks obsolete and rendering the handy mnemonic “My Very Eager Mother Just Served Us Nine Pies” irrelevant (or at least confusing), the decision angered many people around the world, both in and out of the scientific community. Pluto is a planet, they said, it always has been and always will be! Save Pluto! the schoolkids wrote in crayon to planetarium directors. The world all of a sudden realized how much people liked having Pluto as the “last” planet, and didn’t want to see it demoted by decision, especially a highly contested one.
Yet as it turns out, Pluto really may not be a planet after all.
It may be a comet.
But…that’s getting ahead of ourselves. First things first.

Recent discoveries by a UK team of astronomers points to the presence of carbon monoxide in Pluto’s atmosphere. Yes, Pluto has an atmosphere; astronomers have known about it since 1988. At first assumed to be about 100km thick, it was later estimated to extend out about 1500km and be composed of methane gas and nitrogen. This gas would expand from the planet’s – er, dwarf planet’s – surface as it came closer to the Sun during the course of its eccentric 248-year orbit and then freeze back onto the surface as it moved further away. The new findings from the University of St Andrews team, made by observations with the James Clerk Maxwell telescope in Hawaii, identify an even thicker atmosphere containing carbon monoxide that extends over 3000 km, reaching nearly halfway to Pluto’s largest moon, Charon.
It’s possible that this carbon monoxide atmosphere may have expanded outwards from Pluto, especially in the years since 1989 when it made the closest approach to the Sun in its orbit. Surface heating (and the term “heating” is used scientifically here…remember, at around -240ºC (-400ºF) Pluto would seem anything but balmy to us!) by the Sun’s radiation would have warmed the surface and expelled these gases outwards. This also coincides with observations made by the Hubble Space Telescope over the course of four years, which revealed varying patterns of dark and light areas on Pluto’s surface – possibly caused by the thawing of frozen areas that shift and reveal lighter surface material below.
“Seeing such an example of extra-terrestrial climate-change is fascinating. This cold simple atmosphere that is strongly driven by the heat from the Sun could give us important clues to how some of the basic physics works, and act as a contrasting test-bed to help us better understand the Earth’s atmosphere.”
– Dr. Jane Greaves, Team Leader
In fact, carbon monoxide may be the key to why Pluto even still has an atmosphere. Unlike methane, which is a greenhouse gas, carbon monoxide acts as a coolant; it may be keeping Pluto’s fragile atmosphere from heating up too much and escaping into space entirely! Over the decades and centuries that it takes for Pluto to complete a single year, the balance between these two gases must be extremely precise.
So here we have Pluto exhibiting an expanding atmosphere of thawing expelled gas as it gets closer to the Sun in an elliptical, eccentric orbit. (Sound familiar?) And now there’s another unusual, un-planet-like feature that’s being put on the table: Pluto may have a tail.
Actually this is an elaboration of the research results coming from the same team at the University of St Andrews. The additional element here is a tiny redshift detected in the carbon monoxide signature, indicating that it is moving away from us in an unusual way. It’s possible that this could be caused by the top layers of Pluto’s atmosphere – where the carbon monoxide resides – being blown back by the solar wind into, literally, a tail.
That sounds an awful lot, to this particular astronomy reporter anyway, like a comet.
Just saying.
Anyway, regardless of what Pluto is or isn’t, will be called or used to be called, there’s no denying that it is a fascinating little world that deserves our attention. (And it will be getting plenty of that come July 2015 when the New Horizons spacecraft swings by for a visit!) I’m sure there’s no one here who would argue that fact.
New Horizons’ upcoming visit will surely answer many questions about Pluto – whatever it is – and most likely raise even more.

President Barack Obama and the entire First Family apparently plan to attend the final launch of Space Shuttle Endeavour, according to government officials and multiple news outlets. Endeavour is slated to blast off on the STS-134 mission next Friday, April 29 from the Kennedy Space Center (KSC) in Florida at 3:47 p.m. EDT.
There has already been intense drama surrounding the STS-134 mission because it is being commanded by Mark Kelly. Kelly is the husband of U.S. Congresswoman Gabrielle Giffords of Arizona who was critically wounded by gunshots to her head at point blank range during an assassination attempt while attending a meet and greet with her constituents on Jan. 8, 2011. Six people – including a nine year old girl and a federal judge – were killed and a dozen more were wounded that awful day.

The Presidents appearance at the STS-134 launch will almost certainly lead to skyrocketing interest, but has not yet been officially announced by NASA and the White House. The event is not yet listed on the presidents official schedule.
However, a tweet by the staff of Congresswoman Giffords on her official website states Obama will attend; “We are very happy that Pres. Obama is coming to Mark’s launch! This historic mission will be #Endeavours final flight.”
NASA spokesman Allard Beutel told me today, “I cannot confirm whether the president will be coming to launch next week. If he’s coming, which I can’t confirm, we are a White House agency.”
“We always welcome a visit from the President,” Beutel said.
Security is always tight at KSC during a shuttle launch. A visit by President Obama will certainly lead to even tighter security controls and even more massive traffic jams.
Giant crowds were already expected for this historic final spaceflight of Space Shuttle Endeavour, NASA’s youngest Orbiter, on her 25th mission to space.
Endeavour is carrying the $2 Billion Alpha Magnetic Spectrometer (AMS) ) on a 14-day flight to the International Space Station, a premier science instrument that will collect cosmic rays, search for dark energy, dark matter and anti matter and seeks to determine the origin of the Universe. See my photo below of the AMS from inside the Space Station Processing Facility (SSPF) at KSC with the principal investigator, Nobel Prize winner Prof. Sam Ting of MIT.
President Obama last visited KSC on April 15, 2010 and gave a major policy speech outlining his radical new human spaceflight goals for NASA. Obama decided to cancel NASA’s Project Constellation ‘Return to the Moon’ Program and the Ares 1 and Ares 5 rockets. He directed NASA to plan a mission for astronauts to visit an Asteroid by 2025 and one of the moons of Mars in the 2030’s. Obama also decided to revive the Orion crew module built by Lockheed Martin, which is now envisaged for missions beyond low earth orbit (LEO), and invest in development of new commercial space taxis such as the Dragon spacecraft by SpaceX for transporting astronaut crews to the ISS.
Spokesman Beutel said that during the April 2010 visit, “The President met with space workers.” He could not comment on details of the president’s plans for the STS-134 visit and said information would have to come from the White House.
The last time a sitting president watched a live human space launch was in 1998 when then President Bill Clinton attended the blastoff of the return to space of Astronaut and Senator John Glenn. Glenn was the first American to orbit the Earth back in 1962. Glenn’s first flight took place a little over a year after the historic first human spaceflight by Soviet Cosmonaut Yuri Gagarin on April 12, 1961- which occurred exactly 50 years ago last week.
Congresswoman Giffords is recovering from her wounds and Shuttle Commander Kelly has said that she would like to attend the STS-134 launch. But no official announcement about her attendance has been made by NASA and depends on many factors including decisions by the doctors treating her in a Houston area hospital.

[/caption]
50 Years ago, the dream of human spaceflight opened with the courageous blastoff of Cosmonaut Yuri Gagarin inside the Vostok 1 spacecraft on April 12, 1961. Gagarin was the first person to orbit the Earth. Less than a month later on May 5. 1961, Astronaut Alan Shepard bravely set forth on America’s first human spaceflight – Freedom 7.
Barely three weeks afterward on May 25, 1961, these momentous events of the early Space Age led directly to Project Apollo and the historic announcement by President Kennedy that the United States “would land a man on the moon” by the end of the 1960’s.
In honor of Yuri Gagarin, NASA’s Opportunity Mars Rover explored a small and highly eroded crater dubbed “Vostok Crater” in 2005 during its journey in the Meridian Planum region on the Martian surface. Along the edge of the crater, researchers commanded Opportunity to use the Rock Abrasion Tool (RAT), to drill into a rock dubbed “Gagarin” on Sols 401 and 402 in March 2005.
Opportunity landed on Mars on Jan. 24, 2004 for a planned 90 sol mission. By the time that Opportunity arrived at Vostok Crater, she had already lasted more than 4 times longer than expected and found that water existed on ancient Mars.
Opportunity is still alive today on Sol 2571, more than 28 times beyond its design lifetime !
Opportunity used its rock abrasion tool (RAT) on a rock named "Gagarin" during Sols 401 and 402 on Mars (March 10 and 11, 2005). This false-color image shows the circular mark created where the tool exposed the interior of the rock Gagarin at a target called "Yuri." The circle is about 4.5 centimeters (1.8 inches) in diameter. Gagarin is at the edge of a highly eroded, small crater that was named "Vostok" for the spacecraft that carried Cosmonaut Yuri Gagarin in the first human spaceflight, on April 12, 1961. This image combines exposures taken through three different filters by Opportunity's panoramic camera on Sol 405 (March 14, 2005). Credit: NASA/JPL-Caltech/Cornell Univ./ASU
Scientists are using the data gathered from “Gagarin Rock” and other locations explored by Opportunity to help elucidate the history of the past flow of liquid water on the red planet and determine whether the wet environmental conditions could ever have supported martian microbial life – past or present.
“The 50th anniversary of mankind’s first fledgling foray into the cosmos should serve as an important reminder of the spirit of adventure and exploration that has propelled mankind throughout history,” said Mars rover science team member James Rice of NASA Goddard Space Flight Center, Greenbelt, Md, in a statement. “We are a species of explorers; it is encoded into our very DNA.”
“Half a century ago Yuri Gagarin was lofted into a totally unknown, remote and hostile environment and in doing so opened up a new limitless frontier of possibilities for mankind,” Rice added. “A mere 23 days later another brave human, Alan Shepard, climbed aboard a rocket and ventured into the starry abyss. Their courage and vision continue to inspire and lead us into the unknown. Hopefully, one day in the not too distant future it will lead humanity on a voyage to Mars.”
Many people, including myself, were inspired by the Space Race to become scientists and engineers and hope that continues for the next generation of students today.

NASA Administrator Charles Bolden today unveiled the winners in the bidding war to become home to one of NASA’s retiring space shuttle orbiters. Bolden selected the Kennedy Space Center in Florida, the California Science Center, the Intrepid Sea, Air and Space Museum in New York City, and the Smithsonian National Air and Space Museum, outside Washington D.C.
Bolden made the announcement at a ceremony at the Kennedy Space Center coinciding with the 30th anniversery of the first space shuttle flight. Space Shuttle Columbia blasted off on the STS-1 mission on April 12, 1981. Today is also the 50th anniversary of the first manned spaceflight by Cosmonaut Yuri Gagarin on April12, 1961.
Only two shuttle flights remain before the Space Shuttle Program and the orbiters are retired after 30 years of speceflight and 133 mission so far. The final two missions – STS-134 and STS 135 – are slated for late April and late June 2011.
The orbiters will then be transferred to their new homes and put on display where NASA hopes they will inspire the next generation of explorers and engineers. But the word mentioned by Bolden and all the other speakers was “bittersweet” – because today is a mixture of sadness that the orbiters are being retired while still flight worthy and happiness that the program has achieved so much.
Atlantis, the final shuttle to fly, will be displayed at the Kennedy Space Center Visitor Complex. Kennedy is the natural home to the orbiters and where every shuttle mission has launched and where every shuittle mission is processed for flight.
Kennedy plans to disiplay shuttle Atlantis as though it were “In Flight”. Read my earlier story on Kennedy’s proposal to showcase the orbiter with interactive exhibits and numerous shuttle program artifacts , such as like the White Room and the Beenie Cap.

As expected, Shuttle Discovery was assigned to the Smithsonian’s National Air
and Space Museum Steven F. Udvar-Hazy Center in Virginia. Discovery is the fisrt of the orbiters to be retired and just completed its final mission, STS -133, in March 2011
The prototype orbiter Enterprise, which is currently on display at the Smithsonian, will be moved up the east coast to the Intrepid Sea, Air & Space Museum in New York City
Space Shuttle Endeavour will go to the California Science Center in Los Angeles, near to the location where all the shuttle orbiters were constructed.
