Lockheed Accelerates Orion to Achieve 2013 launch and potential 2016 Manned Lunar Flyby

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.

Orion is NASA’s next generation crew vehicle and is intended to someday replace the Space Shuttle program, which will be fully retired just three months from now.

The second to last shuttle flight – STS 134 – is slated for launch this week on April 29 and President Obama and the entire First Family will attend.

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.

More Surprises From Pluto

[/caption]

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.

The new discovery was presented by team leader Dr. Jane Greaves on Wednesday, April 20 at the National Astronomy Meeting in Wales.

President Obama to Attend Endeavour’s Last Launch on April 29

President Obama plans to attend the last launch of Endeavour on April 29, 2011 at the Kennedy Space Center.

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.

NASA Administrator Charles Bolden just announced that Endeavour will be displayed at the California Science Museum following her retirement from active flight service upon landing.

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.

Yuri Gagarin From the Earth to Mars Tribute

The legacy of Yuri Gagarin and Vostok1 honored by Opportunity Mars Rover at Vostok Crater and Gagarin Rock. Photos: Roscosmos/NASA/JPL Poster: Ken Kremer

[/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.

I created the poster collage above as a tribute to the first human spaceflight by Yuri Gagarin and his legacy which eventually led to the exploration of Mars by the Spirit and Opportunity rovers

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.

Opportunity used its rock abrasion tool on a rock named "Gagarin" during the 401st and 402nd Martian days, or sols, of the rover's work on Mars (March 10 and 11, 2005). This image, taken by Opportunity's navigation camera on Sol 405 (March 14, 2005), shows the circular mark left on the rock. The circle is about 4.5 centimeters (1.8 inches) in diameter. At the end of the rover's arm, the tool turret is positioned with the rock abrasion tool pointing upward in this image. The abrasion target on the rock Gagarin was informally named "Yuri."

NASA Selects Museums in Florida, California, New York and the Smithsonian for retiring Space Shuttles

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. Endeavour will be the only orbiter to be display outside the east coast. Endeavour is being processed for her final flight, the STS-134 mission, set to launch on April 29.

Oddly left out is the Johnson Space Center, home to all the Space Shuttle astronauts and their training facilities.

Today, April 12, is the 50th Anniversary of Earth’s first manned spaceflight by Hero Cosmonaut , Yuri Gagarin of what was then the Soviet Union. He was strapped aboard the Vostok 1 spacecraft and blasted off to the High Froniter at 9:07 a.m. Moscow time from the Baikonur Cosmodrome

Roskosmos – the Russian Federal Space Agency – honors his memory with this stirring video tribute chronicling the Flight of Yuri Gagarin. The outstanding video is set to the song “Seed” with lyrics sung by the Russian Red Army Choir. Dramatic video clips show rare views of Gagarin in training, the actual launch day events and concludes with his grand reception.

Gagarin’s smile is infectious and the video brings him to life. Watch and enjoy – several times . And be prepared to journey back in time to the era of the Space Race and the Soviet Union.

Included below is another music video with more amazing videos clips from the Flight of Yuri Gagarin on April 12, 1961and a brief video summarizing his all too short life. Gagarin would have been celebrating his 75th birthday on March 9.

Today, people around the globe will celebrate the historic occasion at over 500 Yuri’s Night Events. You can still join in the fun and attend. Find out how at the Yuri Night Website. Or join Ken in Princeton Junction, New Jersey for a free talk about Yuri and another historic space milestone, the 30th Anniversary of the first shuttle flight: STS -1.

50 Years ago on April 12,1961 the era of Human spaceflight opened with a roar to the heavens above with the thunderous blastoff of Cosmonaut Yuri Gagarin aboard the Vostok 1 capsule from the Baikonur Cosmodrome Site No.1 at 9:07 a.m. Moscow time. Gagarin, at the age of 27, dared to brave the perils of the unknown and became the first human being to be strapped atop a rocket, ascend to outer space and view what no one else had ever seen, the entire Earth as a sphere. A bold and courageous test flight in every dimension. And the effects of weightlessness had only been tested on dogs – not people.

Herein is a picture album of significant launch day events, including three collages of rare photos of Yuri Gagarin climbing up the launch tower and boarding the Vostok 1 spacecraft for the historic liftoff of the first manned spaceflight on April 12, 1961.

Sergei Korolev, “Chief Designer” of the Soviet Space program radioed, “LIFT OFF! We wish you a good flight. Everything is all right.”

“Poyekhali!”, Gagarin replied “[Off we go!].”

“I see Earth! It is so beautiful!” Gagarin said from orbit. “I see rivers. Visibility is good.”

Roscosmos, the Russian Federal Space Agency, put out a call for anyone interested in Yuri Gagarin and the birth of the human space exploration era to share their documents, photos and other information with the public – and the fabulous collages resulted from the response.

Do you have photos or memories of Gagarin ? Send them to Ken. Gagarin traveled widely as an ambassador of goodwill, bridging the dangerous ideological gulf between East and West during the height of the Cold War.

Gagarin’s flight lasted 108 minutes for a single orbit around the Earth. The mission was brought to a close with the de-orbit firing of the reentry rockets. Gagarin ejected from the capsule at 7 km altitude because the hard landing of the capsule was too dangerous for people. So he parachuted safely to the ground. April 12 has been celebrated as Cosmonautics Day in Russia every year since 1962. Vostok 1 was Gagarin’s only flight

Tragically, Gagarin’s life ended on March 27, 1968. He was flying a routine training mission in a MiG-15UTI fighter with flight instructor Vladimir Seryogin when the plane suddenly crashed near the town of Kirzhach. Gagarin was laid to rest in the wall of the Kremlin on Red Square.

In honor of this 50th anniversary of the dawn of Human spaceflight, a global network of over 444 Yuri’s Night parties are being staged worldwide on April 12, 2011 to celebrate one of the humankind’s greatest achievements – that’s double the number from 2010.

20 years after Gagarin’s flight, NASA’s first space shuttle blasted off on the STS-1 mission on April12, 1981.

You can join in the local Yuri’s Night festivities taking place in more than 70 countries from Afghanistan (visited by Gagarin in Dec. 1961) to Vietnam. Or join Ken in Princeton Junction, New Jersey for a free presentation about Gagarin’s flight and my behind the scenes look at the space shuttle and beyond.

Astronomy Without A Telescope – Our Unlikely Solar System

Recent modeling of Sun-like stars with planetary systems, found that a system with four rocky planets and four gas giants in stable orbits – and only a sparsely populated outer belt of planetesimals – has only a 15 to 25% likelihood of developing. While you might be skeptical about the validity of a model that puts our best known planetary system in the unlikely basket, there may be some truth in this finding.

This modeling has been informed by the current database of known exoplanets and otherwise based on some prima facie reasonable assumptions. Firstly, it is assumed that gas giants are unable to form within the frost line of a system – a line beyond which hydrogen compounds, like water, methane and ammonia would exist as ice. For our Solar System, this line is about 2.7 astronomical units from the Sun – which is roughly in the middle of the asteroid belt.

Gas giants are thought to only be able to form this far out as their formation requires a large volume of solid material (in the form of ices) which then become the cores of the gas giants. While there may be just as much rocky material like iron, nickel and silicon outside the frost line, these materials are not abundant enough to play a significant role in forming giant planets and any planetesimals they may form are either gobbled up by the giants or flung out of orbit.

However, within the frost line, rocky materials are the dominant basis for planet forming – since most light gas is blown out of the region by force of the stellar wind and other light compounds (such as H₂O and CO₂) are only sustained by accretion within forming planetesimals of heavier materials (such as iron, nickel and silicates). Appreciably-sized rocky planets would probably form in these regions within 10-100 million years after the star’s birth.

So, perhaps a little parochially, it is assumed that you start with a system of three regions – an inner terrestrial planet forming region, a gas giant forming region and an outer region of unbound planetesimals, where the star’s gravity is not sufficient to draw material in to engage in further accretion.

From this base, Raymond et al ran a set of 152 variations, from which a number of broad rules emerged. Firstly, it seems that the likelihood of sustaining terrestrial inner planets is very dependent on the stability of the gas giants’ orbits. Frequently, gravitational perturbations amongst the gas giants results in them adopting more eccentric elliptical orbits which then clears out all the terrestrial planets – or sends them crashing into the star. Only 40% of systems retained more than one terrestrial planet, 20% had just one and 40% had lost them all.

The Moon has retained a comprehensive record of the Late Heavy Bombardment from 4.1 to 3.8 billion years ago - resulting from a reconfiguration of the gas giants. As well as clearing out much of debris disk of the early Solar System, this reconfiguration flung material into the inner solar system to bombard the rocky planets.

Debris disks of hot and cold dust were found to be common phenomena in matured systems which did retain terrestrial planets. In all systems, primal dust is largely cleared out within the first few hundred million years – by radiation or by planets. But, where terrestrial planets are retained, there is a replenishment of this dust – presumably via collisional grinding of rocky planetesimals.

This finding is reflected in the paper’s title Debris disks as signposts of terrestrial planet formation. If this modeling work is an accurate reflection of reality, then debris disks are common in systems with stable gas giants – and hence persisting terrestrial planets – but are absent from systems with highly eccentric gas giant orbits, where the terrestrial planets have been cleared out.

Nonetheless, the Solar System appears as unusual in this schema. It is proposed that perturbations within our gas giants’ orbits, leading to the Late Heavy Bombardment, were indeed late with respect to how other systems usually behave. This has left us with an unusually high number of terrestrial planets which had formed before the gas giant reconfiguration began. And the lateness of the event, after all the collisions which built the terrestrial planets were finished, cleared out most of the debris disk that might have been there – apart from that faint hint of Zodiacal light that you might notice in a dark sky after sunset or before dawn.

Mark your calendars. April 12, 2011 marks the 50th Anniversary of Human Spaceflight and Cosmonaut Yuri Gagarin’s astonishing First Orbit of our precious planet Earth on April 12, 1961. Gagarin was the first human to enter outer space and see what no one else had ever witnessed – our commonly shared Earth as a planet and beautiful blue globe with no borders.

Space enthusiasts worldwide are celebrating this watershed moment in Human history at a network of over 400 “Yuri’s Night” parties taking place in more than 70 countries on 6 continents and 2 worlds, according to the official “Yuri’s Night” website.

Gagarin’s flight took place in the midst of the inflammatory Cold War rivalry between the Soviet Union and the United States and shocked the world into new realities. The Space Race led to the first lunar landing by the United States and Neil Armstrong’s first steps on the moons surface in 1969. Eventually, the world’s superpowers beat swords into plowshares and united their efforts to build the International Space Station.

Yuri Gagarin was the first person to boldly leave the bonds of Earth’s gravity and thus became the first “Spaceman”. Gagarin blasted off inside the bell-shaped Vostok 1 spaceship from the launch pad at Baikonur at 9:07 a.m, Moscow time (607 UTC) to begin the era of human spaceflight.

Gagarin flew around the Earth in a single orbit at an altitude of 302 kilometers (187 miles). The flight lasted 108 minutes and safely ended when he descended back and parachuted to the ground, just north of the Caspian Sea. At the age of 27, Gagarin was instantly transformed into a worldwide hero. After the momentous flight he soon embarked on an international tour.

20 years later on April 12, 1981, NASA’s first space shuttle blasted off on the STS-1 mission on a daring test flight with astronauts John Young and Bob Crippen strapped inside Space Shuttle Columbia.

The first “Yuri’s Night – World Space Party” was held on April 12, 2001 to commemorate the 40th anniversary of Gagarin’s spaceflight. Over 10,000 people attended 64 events located worldwide. The goal was to inspire people, increase awareness and support for space exploration across the globe and foster the spread of new ideas to broaden our access to space.

“Yuri’s Night” has been growing in popularity every year. Events range in size from a few folks to numbers in the thousands. Attendees range from astronauts and cosmonauts, NASA and global space agency officials and reps, scientists and engineers, famous actors, playwrights, writers, artists, athletes and musicians to just everyday folks and kids of all ages and backgrounds. Everyone can get involved.

In honor of the 50th anniversary of Gagarin’s flight, documentary film maker Christopher Riley conceived and created a film titled “First Orbit” to try and show the approximate view of Earth that Gagarin actually saw. There is only scant footage of Gagarin’s actual flight and he himself took no pictures of the Earth from orbit.

“First Orbit” recreates much of the view of the Earth’s surface that Gagarin would have seen fifty years ago. Mostly he flew over the world oceans as well as the Soviet Union and Africa.

Riley collaborated with the astronauts aboard the International Space Station, chiefly Paolo Nespoli of ESA, who took film footage from the new 7 windowed Cupola as the station matched the actual flight path of Gagarin and Vostok 1 as closely as possible. The free film celebrates 50 years of human spaceflight.

“First Orbit” premiers worldwide on YouTube in a special global streaming event for Yuri’s Night on April 12 . Watch the short trailer below, with original and stirring music by Philip Sheppard.

It’s easy and free to register your local party at the Yuri’s Night event website. There is still time to register your Yuri’s Night party – Indeed the list has grown as I typed out this story !

Some events are already set to kick off this weekend. I’ll be presenting at an interactive and free Yuri’s Night evening event in Princeton Junction, New Jersey, about Gagarin’s flight and my experiences with the space shuttle and what‘s beyond.

Curiosity Mars Rover Almost Complete

[/caption]

NASA’s massive ‘Curiosity’ rover is almost ready to begin the first leg of its long trek to the surface of the Red Planet. Engineers at NASA’s Jet Propulsion Laboratory in California are nearly finished with assembling and testing all the components of the Mars Science Laboratory (MSL) mission (see photos above and below).

The MSL team plans to ship Curiosity as well as the cruise stage, descent stage and back shell to the Kennedy Space Center (KSC) in May and June. After arriving at KSC, all the pieces will be integrated together and tested during final assembly in a clean room. The rover will then be installed inside a 5 meter diameter nose cone, shipped the short distance to Cape Canaveral and then bolted atop an Atlas V rocket (photo below).

The launch window for Curiosity extends from Nov. 25 to Dec. 18, 2011. The first stage of the powerful Atlas V rocket will be augmented with four solid rocket boosters. The Atlas V has previously launched two planetary missions; the Mars Reconnaissance Orbiter (MRO) and the New Horizons mission to Pluto.

Take a long gander at the 3 meter long rover because its appearance is now very much how it will look while it’s roving along intriguing martian landscapes for at least two earth years after landing in August 2012.

The mini-Cooper sized Curiosity rover is equipped with 10 science instruments to investigate Martian soil and rock samples in far greater detail than ever before. Curiosity’s science payload weighs ten times more than any prior Mars rover mission.

The goal is to search for clues to environmental conditions favorable for microbial life and for preserving evidence about whether Martian life ever existed in the past or today. NASA is scrutinizing a list of four potential landing sites for the best chance of finding a habitable zone.
