When NASA’s next generation human spaceflight vehicle Orion blasts off on its maiden unmanned test flight later this year, a radiation experiment designed by top American high school students will soar along and play a key role in investigating how best to safeguard the health of America’s future astronauts as they venture farther into deep space than ever before – past the Moon to Asteroids, Mars and Beyond!

The student designed radiation experiment was the centerpiece of a year-long Exploration Design Challenge (EDC) competition sponsored by NASA, Orion prime contractor Lockheed Martin and the National Institute of Aerospace, and was open to high school teams across the US.

The winning experiment design came from a five-member team of High School students from the Governor’s School for Science and Technology in Hampton, Va. and was announced by NASA Administrator Charles Bolden at the opening of the 2014 U.S.A Science and Engineering Festival held in Washington, DC on April 25.

The goal of the EDC competition was to build and test designs for shields to minimize radiation exposure and damaging human health effects inside NASA’s new Orion spacecraft slated to launch into orbit during the Exploration Flight Test-1 (EFT-1) pathfinding mission in December 2014. See experiment design photo herein.

During the EFT-1 flight, Orion will fly through the dense radiation field that surrounds the Earth in a protective shell of electrically charged ions – known as the Van Allen Belt – that begins 600 miles above Earth.

No humans have flown through the Van Allen Belt in more than 40 years since the Apollo era.

Team ARES from Hampton VA was chosen from a group of five finalist teams announced in March 2014.

“This is a great day for Team ARES – you have done a remarkable job,” said NASA Administrator Bolden.

“I really want to congratulate all of our finalists. You are outstanding examples of the power of American innovation. Your passion for discovery and the creative ideas you have brought forward have made us think and have helped us take a fresh look at a very challenging problem on our path to Mars.”

Since Orion EFT-1 will climb to an altitude of some 3,600 miles, the mission offers scientists the opportunity to understand how to mitigate the level of radiation exposure experienced by the astronaut crews who will be propelled to deep space destinations beginning at the end of this decade.

The student teams used a simulation tool named OLTARIS, the On- Line Tool for the Assessment of Radiation in Space, used by NASA scientists and engineers to study the effects of space radiation on shielding materials, electronics, and biological systems.

Working with mentors from NASA and Lockheed Martin, each team built prototypes and used the OLTARIS program to calculate how effective their designs – using several materials at varying thicknesses – were at shielding against radiation in the lower Van Allen belt.

“The experiment is a Tesseract Design—slightly less structurally sound than a sphere, as the stresses are located away from the cube on the phalanges. The materials and the distribution of the materials inside the tesseract were determined through research and simulation using the OLTARIS program,” Lockheed Martin spokeswoman Allison Rakes told me.

The students conducted research to determine which materials were most effective at radiation shielding to protect a dosimeter housed inside – an instrument used for measuring radiation exposure.

“The final material choices and thicknesses are (from outermost to innermost): Tantalum (.0762 cm/ .030 in), Tin (.1016 cm/ .040 in), Zirconium (.0762 cm/ .030 in), Aluminum (.0762 cm/ .030 in), and Polyethylene (9.398 cm/ 3.70 in),” according to Rakes.

At the conclusion of the EFT-1 flight, the students will use the measurement to determine how well their design protected the dosimeter.

But first Team ARES needs to get their winning proposal ready for flight. They will work with a NASA and Lockheed Martin spacecraft integration team to have the experimental design approved, assembled and installed into Orion’s crew module.

All the students hard work will pay off this December when Lockheed Martin hosts Team ARES at the Kennedy Space Center in Florida to witness the liftoff of their important experiment inside Orion atop the mammoth triple barreled Delta IV Heavy booster.

46 teams from across the country submitted engineering experiment proposals to the EDC aimed at stimulating students to work on a science, technology, engineering and math (STEM) project that tackles one of the most significant dangers of human space flight — radiation exposure.

“The Exploration Design Challenge has already reached 127,000 students worldwide – engaging them in real-world engineering challenges and igniting their imaginations about the endless possibilities of space discovery,” said Lockheed Martin Chairman, President and CEO Marillyn Hewson.

The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.

Stay tuned here for Ken’s continuing Orion, Orbital Sciences, SpaceX, commercial space, LADEE, Curiosity, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

LADEE Sees Zodiacal Light before Crashing into Moon, but Apollo Mystery Remains

NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) literally ‘saw the light’ just days before crashing into the lunar farside last Thursday April 17. Skimming just a few kilometers above the moon’s surface, mission controllers took advantage of this unique low angle to gaze out over the moon’s horizon in complete darkness much like the Apollo astronauts did from lunar orbit more than 40 years ago.

With the glow of Earth well-hidden, any dust in the moon’s scant atmosphere around the time of orbital sunrise should become visible. Scientists also expected to see the softly luminous glow of the zodiacal light, an extensive cloud of comet and asteroid dust concentrated in the flat plane of the solar system. The zodiacal light gets its name from the zodiac, that familiar band of constellations the planets pass through as they orbit the sun. Back on Earth, the zodiacal light looks like a big thumb of light standing up from the western horizon a couple hours after sunset in spring and before sunrise in fall.

So what did LADEE see? As you watch the animation above, comprised of images taken from darkness until sunrise, you’ll see a yellow haze on the horizon that expands into large diffuse glow tilted slightly to the right. This is the zodiacal light along with a smaller measure of light coming from sun’s outer atmosphere or corona. Together they’re referred to as CZL or ‘coronal and zodiacal light’. At the very end, the sun peaks over the lunar horizon.

This is a sketch of the lunar sunrise seen from orbit by Apollo 17 astronaut Eugene Cernan. On the right, the sketch is highlighted to show the sources of the scattered light: red indicates Coronal and Zodiacal Glow, blue is the Lunar Horizon Glow, perhaps caused by exospheric dust, and green indicates possible "streamers" of light (crepuscular rays) formed by shadowing and scattered light.

What appears to be missing from the pictures are the mysterious rays seen by some of the Apollo astronauts. The rays, neatly sketched by astronaut Eugene Cernan of Apollo 17, look a lot like those beams of light and shadow streaming though holes in clouds called crepuscular rays.

Only thing is, Earth’s atmosphere is thick enough for cloud beams. The dust in the moon’s atmosphere appears much too thin to cause the same phenomenon. And yet the astronauts saw rays as if sunlight streamed between mountain peaks and scattered off the dust just like home.

It’s believed that dust gets lofted into the spare lunar atmosphere via electricity. Ultraviolet light from the sun knocks electrons from atoms in moon dust, giving them a positive charge. Since like charges repel, bits of dust push away from one another and move in the direction of least resistance: up. The smaller the dust particle, the higher it rises until dropping back down to the surface. Perhaps these “fountains” of lunar dust illuminated by the sun are what the astronauts recorded.

Unlike Cernan, LADEE saw only the expected coronal and zodiacal light but no rays. Scientists plan to look more closely at several sequences of images made of lunar sunrise in hopes of finding them.

Remembering John Houbolt: the Man Who Gave Us Lunar Orbit Rendezvous

The space community lost a colossus of the of the Apollo era last week, when John Houbolt passed away last Tuesday just five days after his 95^th birthday.

Perhaps the name isn’t as familiar to many as Armstrong or Von Braun, but John Houbolt was a pivotal figure in getting us to the Moon.

Born in Altoona, Iowa on April 10^th, 1919, Houbolt spent most of his youth in Joliet, Illinois. He earned a Masters degree in Civil Engineering from the University of Illinois at Urbana-Champaign in 1942 and a PhD in Technical Sciences from ETH Zurich in Switzerland in 1957. But before that, he would become a member of the National Advisory Committee for Aeronautics (NACA) in 1942, an organization that would later become the National Aeronautics and Space Administration or NASA in 1958.

It was 1961 when Houbolt made what would be his most enduring mark on the space program. He was working as an engineer at the Langley Research Center, at a time when NASA and the United States seriously needed a win in the space race. The U.S.S.R. had enjoyed a long string of firsts, including first satellite in orbit (Sputnik 1, October 1957), first spacecraft to photograph the lunar farside (Luna 3 in October 1959) and first human in space with the launch of Yuri Gagarin aboard Vostok 1 in April 1961. A young President Kennedy would make his now famous “We choose to go to the Moon…” speech at Rice University later the next year in late 1962. Keep in mind, in U.S. astronaut John Glenn had just made his first orbital flight months before Kennedy’s speech, and total accumulated human time in space could be measured in mere hours. Unmanned Ranger spacecraft were having a tough time even getting off of the pad, and managing to crash a space probe into the Moon was considered to be a “success”. The task of sending humans “by the end of this decade” was a daunting one indeed…

NASA would soon have a mandate to sent humans to the Moon: but how could they pull it off?

Early ideas for manned lunar missions envisioned a single gigantic rocket that would head to the Moon and land, Buck Rodgers style, “fins first.” Such a rocket would have to be enormous, and carry the fuel to escape Earth’s gravity well, land and launch from the Moon, and return to Earth.

A second approach, known as Earth-orbit rendezvous, would see several launches assemble a mission in low Earth orbit and then head to the Moon. Curiously, though this was an early idea, it was never used in Apollo, though it was briefly resurrected during the now defunct Constellation Program.

Three plans to go to the Moon. Credit: NASA.

But it was a third option that intrigued Houbolt, known as Lunar Orbit Rendezvous. LOR had been proposed by rocket pioneers Yuri Kondratyuk and Hermann Oberth in 1923, but had never been seriously considered. It called for astronauts to depart the Earth in a large rocket, and instead, use a small lander designed only to land and launch from the Moon while the spacecraft for Earth return orbited overhead.

Houbolt became a staunch advocate for the idea, and spent over a year convincing NASA officials. In one famous letter to NASA associate administrator Robert Seamans, Houbolt was known to have remarked “Do we want to go to the Moon or not?”

It’s interesting to note that it was probably only in a young organization like the NASA of the early 1960s that, in Houbolt’s own words, a “voice in in the wilderness” could be heard. Had NASA become a military run organization — as many advocated for in the 1950s — a rigid chain of command could have meant that such brash ideas as Houbolt’s would have never seen the light of day. Thank scientists such as James Van Allen for promoting the idea of a civilian space program that we take for granted today.

Even then, selling LOR wasn’t easy. The idea looked preposterous: astronauts would have to learn how to undock and dock while orbiting a distant world, with no chance of rescue. There was no second chance, no backup option. Early plans called for an EVA for astronauts to enter the Lunar Module prior to descent which were later scrapped in favor of extracting it from atop the third stage and boarding internally before reaching the Moon.

Once Houbolt had sold key visionaries such as Wernher von Braun on the idea in late 1962, LOR became the way we would go to the Moon. And although Houbolt’s estimations of the mass required for the Lunar Module were off by a factor of three, the story is now the stuff of early Apollo era legend. You can see Houbolt (played by Reed Birney) and the tale of the LM and LOR in the From Earth to the Moon episode 5 entitled “Spider”.

Houbolt was awarded NASA’s medal for Exceptional Scientific Achievement in 1963, and he was in Mission Control When Apollo 11 touched down in the Sea of Tranquility.

He passed away in a Scarborough, Maine nursing home last Tuesday, and joins other unsung visionaries of the early space program such as Mary Sherman Morgan. It’s sad to think that we may soon live in a world where those who not only walked on the Moon, but those who also sent us and knew how to get there, are no longer with us.

Thanks, John… you gave us the Moon.

SpaceX Leases Historic Launch Complex 39A from NASA for new Era of Commercial Space Launches

The keys to NASA’s historic launch Pad 39A that propelled humanity’s first man to walk on the Moon – Neil Armstrong – during the history making flight of Apollo 11, have been handed over to new owners, namely the private aerospace firm SpaceX for a new purpose – serving as a commercial launch facility.

NASA and Space Exploration Technologies Corporation (SpaceX) of Hawthorne, Calif., have just signed an agreement giving SpaceX rights to occupy and operate seaside Launch Complex 39A at the Kennedy Space Center (KSC) in Florida.

SpaceX was founded by billionaire, entrepreneur and space visionary Elon Musk.

SpaceX aims to give the now dormant pad a new lease on life in the emerging New Space era by revitalizing it as a commercial launch site for the company’s mammoth new Falcon Heavy rocket, currently under development, as well as for manned launches of the firm’s human rated Dragon spacecraft atop the Falcon 9 according to Gwynne Shotwell, president of SpaceX.

“We’ll make great use of this pad, I promise,” Shotwell told reporters at a briefing at the pad.

The liquid fueled Falcon Heavy will be the most powerful rocket in the world according to SpaceX, generating generating nearly four million pounds of liftoff thrust from 27 engines and thus significantly exceeding the power of the Delta IV Heavy manufactured by competitor United Launch Alliance.

Shotwell said renovations to pad 39A would start later this year. The maiden SpaceX launch from the complex is expected next year.

“We will launch the Falcon Heavy from here from this pad early next year,” Shotwell stated.

The SpaceX Dragon is one of three commercial crew vehicles being developed under a public-private partnership with NASA to ferry US astronauts to the International Space Station (ISS) and restore America’s human spaceflight capability lost since the shuttle’s retirement.

The Boeing CST-100 and Sierra Nevada Dream Chaser are also vying for the next round of private ‘space taxi’ funding from NASA.

Pad 39A has been inactive and mothballed since the last shuttle mission, STS-135, thundered to space in July 2011.

Not a single rocket has rolled up the ramp at KSC in nearly 3 years.

The new lease agreement was signed by NASA and SpaceX officials and announced onsite at Pad 39 at the briefing.

“Today this historic site from which numerous Apollo and space shuttle missions began and from which I first flew and left the planet on STS-61C on Columbia, is beginning a new mission as a commercial launch site,” said NASA Administrator Charles Bolden.

“While SpaceX will use pad 39A at Kennedy, about a mile away on pad 39B, we’re preparing for our deep space missions to an asteroid and eventually Mars. The parallel pads at Kennedy perfectly exemplify NASA’s parallel path for human spaceflight exploration — U.S. commercial companies providing access to low-Earth orbit and NASA deep space exploration missions at the same time.”

Under terms of the new agreement with NASA, the lease with SpaceX spans 20 years.

“It’s exciting that this storied NASA launch pad is opening a new chapter for space exploration and the commercial aerospace industry,” said Bolden.

SpaceX will also maintain and operate Pad 39A at its own expense, with no US federal funding from NASA.

Pad 39A will be SpaceX’s third launch site. The company also launches its Falcon 9 rockets from nearby Pad 40 on Cape Canaveral Air Force Station and a west coast pad on Vandenberg Air Force Base, Calif.

Launch Pad 39A has lain dormant save dismantling since the final shuttle launch on the STS-135 mission in July 2011. Not a single rocket has rolled up this ramp in nearly 3 years. SpaceX has now leased Pad 39A from NASA and American rockets will thunder aloft again with Falcon rocket boosters starting in 2015.

The next Falcon 9 liftoff with an unmanned Dragon cargo freighter is currently slated from Friday, April 18 following Monday’s scrub.

NASA determined that the agency no longer has a use for pad 39A since the end of the shuttle era and has been looking for a new tenant to take over responsibility and pay for maintenance of the launch complex. The agency awarded the lease to SpaceX in December 2013.

Instead, NASA decided to completely upgrade, renovate and modernize Pad 39As twin, namely Launch Pad 39B, and invested in converting it into a 21st Century launch complex.

NASA will use Pad 39B to launch the state of the art Orion crew vehicle atop the new Space Launch System (SLS) booster for voyages beyond Earth and taking humans back to the vicinity of the Moon and further out on deep space missions to Asteroids, Mars and beyond.

The first unmanned SLS test flight from Pad 39B is slated for late 2017.

Pad 39A was an active NASA launch pad for nearly 35 years starting back near the dawn of the Space Age in the 1960s.

Apollo 4 was the first NASA booster to blast off from Pad 39A on Nov. 9, 1967 during the historic inaugural test flight of the Saturn V moon rocket that eventually served to dispatch all six US manned lunar landing missions.

The closing NASA use of Pad 39A took place on July 8, 2011 with the launch of STS-135 and orbiter Atlantis on the final flight of the space shuttle era.

The four person STS-135 crew delivered the last US pressurized module to the massive low-Earth orbiting ISS.

No Americans have launched to space from American soil since STS-135.

Launch Complex 39 was originally constructed to launch the Apollo moon landing missions atop NASA’s Saturn V booster in the 1960s and 1970s. Both pads were later modified to support the Space Shuttle program whose first launch took place in 1981 from pad 39A.

“Kennedy Space Center is excited to welcome SpaceX to our growing list of partners,” Center Director Bob Cabana said. “As we continue to reconfigure and repurpose these tremendous facilities, it is gratifying to see our plan for a multi-user spaceport shared by government and commercial partners coming to fruition.”

Stay tuned here for Ken’s continuing SpaceX, Orbital Sciences, commercial space, Orion, Chang’e-3, LADEE, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

Contest entry details below – deadline soon[/caption]

When will LADEE hit the Moon for its looming end of mission finale?

NASA’s resoundingly successful LADEE lunar dust exploring mission is nearly out of gas – and needs your help, now!

With its inevitable doom approaching, NASA needs you to summon your thoughts and is challenging you to participate in a ‘Take the Plunge’ contest – figuratively not literally – and guess LADEE’s impending impact date.

LADEE, which stand for Lunar Atmosphere and Dust Environment Explorer, will smack violently into the Moon and scatter into zillions of bits and pieces sometime in the next two and a half weeks, on or before about April 21.

But exactly when will it impact the lunar surface? NASA wants to hear your best guess!

The ‘Take the Plunge’ contest was announced by NASA today, April 4, at a media briefing.

For more information about the challenge and how to enter, visit: http://socialforms.nasa.gov/ladee

Between now and its inevitable doom, mission controllers will command LADEE to continue gathering groundbreaking science.

And it will do so at an even lower attitude that it orbits today by firing its orbit maneuvering thrusters tonight and this weekend.

The couch sized probe seeks to eek out every last smidgeon of data about the Moons ultra tenuous dust and atmospheric environment from an ultra low altitude just a few miles (km) above the pockmarked lunar surface.

But because the moon’s gravity field is so uneven, the probes thrusters must be frequently fired to keep it on course and prevent premature crashes.

“The moon’s gravity field is so lumpy, and the terrain is so highly variable with crater ridges and valleys that frequent maneuvers are required or the LADEE spacecraft will impact the moon’s surface,” said Butler Hine, LADEE project manager at Ames.

“Even if we perform all maneuvers perfectly, there’s still a chance LADEE could impact the moon sometime before April 21, which is when we expect LADEE’s orbit to naturally decay after using all the fuel onboard.”

LADEE will fly as low as fly approximately 1 to 2 miles (2 to 3 kilometers) above the surface.

Everyone of all ages is eligible to enter NASA’s “Take the Plunge: LADEE Impact Challenge.”

The submissions deadline is 3 p.m. PDT Friday, April 11.

NASA says that winners post impact. They will receive a commemorative, personalized certificate from the LADEE program via email.

Watch for my upcoming story on LADEE’s science accomplishments and what’s planned for her final days.

LADEE was launched on Sept. 6, 2013 from NASA Wallops in Virginia on a science mission to investigate the composition and properties of the Moon’s pristine and extremely tenuous atmosphere, or exosphere, and untangle the mysteries of its lofted lunar dust dating back to the Apollo Moon landing era.

The science mission duration had initially been planned to last approximately 100 days and finish with a final impact on the Moon on about March 24th.

NASA granted LADEE a month long extension since the residual rocket fuel is more than anticipated due to the expertise of LADEE’s navigation engineers and the precision of the launch atop the Orbital Sciences Minotaur V rocket and orbital insertion.

Stay tuned here for Ken’s continuing LADEE, Chang’e-3, Orion, Orbital Sciences, SpaceX, commercial space, Mars rover and more planetary and human spaceflight news.

The Moon Is Just 95 Million Years Younger Than The Solar System: Study

Stuff from Earth’s interior, combined with simulations, have one research team pinning down the Moon’s age to only 95 million years after the Solar System formed (which would make our closest satellite about 4.4 billion years old.)

The simulation involved replicating how the Earth and the other terrestrial planets (Mercury, Venus and Mars) grew from a protoplanetary disc surrounding the young Sun. After 259 simulations, the researchers uncovered a link between when a Mars-sized object smacked Earth (eventually forming the Moon) and how much material Earth gained after the crash.

“This correlation just jumped out of the simulations and held in each set of old simulations we looked at,” stated Seth Jacobson of the Observatory of Cote d’Azur in France, who led the study.

Researchers are calling this a “geologic clock” that dates the Moon independently from the samples Apollo astronauts collected from the moon in the 1960s and 1970s, which were dated using radioactive decay of atomic nuclei. The Earth’s mass was estimated using previously published material examining how plentiful “siderophile” (iron-associated) elements were in Earth’s mantle.

The exact date, for the curious, puts the Moon’s formation at 95 ±32 million years after the solar system began. The measurement agrees with some, but not all, radioactive dating methods.

The researchers argue that this new understanding will help scientists figure out which of the radioactive dating methods are the most useful to figure out the Moon’s age, but it will be interesting to see what other teams think of that conclusion.

Neil Armstrong: Why The World Needs ‘Nerdy Engineers’ (In Animated Form)

Combine the gravitas of humanity’s first moon visitor with the whimsy of animation, and the result is pure fun. Here, you can see part of Neil Armstrong’s address to the National Press Club on Feb. 22, 2000 about how engineering made the world a lot better in the past century. Providing animation is PhD Comics creator Jorge Cham.

“Engineering helped create a world in which no injustice could be hidden,” the retired NASA astronaut (now deceased) said in that speech, explaining that engineering is more focused on envisioning possibilities than the facts-based science professions.

While Armstrong makes no direct reference to his historic 1969 moon landing in the speech, the animation is peppered with references including the famous “bootprint” picture taken by his crewmate, Buzz Aldrin.

We’d be interested in knowing what scientists or science fans think of his point of view. Is Armstrong’s view too limited for science, or an accurate description? Watch the video, and let us know in the comments.

CAPE CANAVERAL AIR FORCE STATION, FL – Production and assembly of virtually all of the key hardware elements for NASA’s eagerly anticipated Orion EFT-1 uncrewed test flight are either complete or nearing completion at the Kennedy Space Center and Cape Canaveral.

Two of the three first stage boosters comprising the mammoth Delta IV Heavy rocket that will propel Orion to high Earth orbit have arrived at Cape Canaveral Air Force Station, Florida, and were unveiled this week by top NASA managers at a media briefing attended by Universe Today.

The triple barreled Delta IV Heavy rocket is currently the most powerful rocket in America’s fleet and the only one capable of launching the Orion EFT-1 capsule to its intended orbit of 3600 miles altitude above Earth.

Due to urgent US national security requirements, the maiden blastoff of the unmanned Orion pathfinder capsule – that will one day send humans back to the Moon and beyond Earth’s realm – has just been postponed about three months from September to December 2014 in order to make way for the accelerated launch of recently declassified US Air Force Space Surveillance satellites – as I reported here.

The center and starboard side boosters recently arrived at the Cape aboard a barge from Decatur, Alabama where they were manufactured by United Launch Alliance (ULA).

The remaining port side booster and the Centaur upper stage are due to be shipped by ULA to Cape Canaveral in April.

“It’s great to see Orion, the next step in our journey of exploration, said NASA Associate Administrator Robert Lightfoot. “And it’s very exciting to see the engines integrated into the booster.”

“This mission is a stepping stone on NASA’s journey to Mars. The EFT-1 mission is so important to NASA. We will test the capsule with a reentry velocity of about 85% of what expect on returning [astronauts] from Mars.”

“We will test the heat shield, the separation of the fairing and exercise over 50% of the eventual software and electronic systems inside the Orion spacecraft. We will also test the recovery systems coming back into the Pacific Ocean.”

Despite the EFT-1 launch postponement, Kennedy Space Center Director Bob Cabana said technicians for prime contractor Lockheed Martin are pressing forward and continue to work around the clock at the Kennedy Space Center (KSC) in order to still be ready in time to launch by the original launch window that opens in mid- September 2014.

“The contractor teams are working to get the Orion spacecraft done on time for the December 2017 launch,” said former shuttle commander Cabana.

“They are working seven days a week in the Operations and Checkout High Bay facility to get the vehicle ready to roll out for the EFT-1 mission and be mounted on top of the Delta IV Heavy.”

“I can assure you the Orion will be ready to go on time, as soon as we get our opportunity to launch that vehicle on its first flight test and that is pretty darn amazing.”

“It’s great to see all the hardware and boosters that will take Orion to orbit.”

Universe Today also confirmed with Cabana that NASA will absolutely not delay any Orion processing and assembly activities.

“Our plan is to have the Orion spacecraft ready because we want to get EFT-1 out so we can start getting the hardware in for Exploration Mission-1 (EM-1) and start processing for that vehicle that will launch on the Space Launch System (SLS) rocket in 2017,” Cabana told me standing besides the Delta IV boosters inside the ULA Horizontal Integration Facility at Cape Canaveral.

Although the mission will only last a few hours it will be high enough to send the vehicle plunging back into the atmosphere and a Pacific Ocean splashdown to test the craft and its heat shield at deep-space reentry speeds of 20,000 mph and endure temperatures of 4,000 degrees Fahrenheit – like those of the Apollo moon landing missions.

The EFT-1 mission will provide engineers with critical data about Orion’s heat shield, flight systems and capabilities to validate designs of the spacecraft, inform design decisions, validate existing computer models and guide new approaches to space systems development. All these measurements will aid in reducing the risks and costs of subsequent Orion flights before it begins carrying humans to new destinations in the solar system.

“Orion EFT-1 is really exciting as the first step on the path of humans to Mars,” said Lightfoot. It’s a stepping stone to get to Mars.”

CAPE CANAVERAL AIR FORCE STATION, FL – The urgent need by the US Air Force to launch a pair of previously classified Space Situational Awareness satellites into Earth orbit this year on an accelerated schedule has bumped the inaugural blastoff of NASA’s highly anticipated Orion pathfinder manned capsule from September to December 2014.

It’s a simple case of US national security taking a higher priority over the launch of NASA’s long awaited unmanned Orion test flight on the Exploration Flight Test-1 (EFT-1) mission.

The EFT-1 flight is NASA’s first concrete step towards sending human crews on Beyond Earth Orbit (BEO) missions since the finale of the Apollo moon landing era in December 1972.

Final assembly of Orion is underway at the Kennedy Space Center (KSC).

The very existence of the covert Geosynchronous Space Situational Awareness Program, or GSSAP, was only recently declassified during a speech by General William Shelton, commander of the US Air Force Space Command.

Shelton made the announcement regarding the top secret GSSAP program during a Feb. 21 speech about the importance of space and cyberspace at the Air Force Association Air Warfare Symposium and Technology exposition, in Orlando, FL.

US national security requirements forced NASA’s Orion EFT-1 mission to swap launch slots with the GSSAP satellites – which were originally slated to launch later in 2014.

Since both spacecraft will blast off from the same pad at Complex 37 and atop Delta rockets manufactured by United Launch Alliance (ULA), a decision on priorities had to be made – and the military won out.

At a Cape Canaveral media briefing with Delta first stage boosters on Monday, March 17, Universe Today confirmed the order and payloads on the upcoming Delta IV rockets this year.

“The firing sequence for the Delta’s is the USAF Global Positioning System GPS 2F-6 [in May], GSSAP [in September] and Orion EFT-1 [in December], Tony Taliancich, ULA Director of East Coast Launch Operations, told me.

Universe Today also confirmed with the top management at KSC that NASA will absolutely not delay any Orion processing and assembly activities.

Despite the EFT-1 postponement, technicians for prime contractor Lockheed Martin are pressing forward and continue to work around the clock at the Kennedy Space Center (KSC) so that NASA’s Orion spacecraft can still meet the original launch window that opens in mid- September 2014 – in case of future adjustments to the launch schedule sequence.

“Our plan is to have the Orion spacecraft ready because we want to get EFT-1 out so we can start getting the hardware in for Exploration Mission-1 (EM-1) and start processing for that vehicle that will launch on the Space Launch System (SLS) rocket in 2017,” Bob Cabana, director of NASA’s Kennedy Space Center and former shuttle commander, told me.

Shelton stated that two of the GSSAP military surveillance satellites would be launched on the same launch vehicle later this year.

“GSSAP will present a significant improvement in space object surveillance, not only for better collision avoidance, but also for detecting threats,” Shelton said.

“GSSAP will bolster our ability to discern when adversaries attempt to avoid detection and to discover capabilities they may have, which might be harmful to our critical assets at these higher altitudes.”

According to a new GSSAP online fact sheet, the program will be a space-based capability operating in near-geosynchronous orbit, supporting U.S. Strategic Command space surveillance operations as a dedicated Space Surveillance Network sensor.

“Some of our most precious satellites fly in that orbit – one cheap shot against the AEHF [Advanced Extremely High Frequency] constellation would be devastating,” added Shelton. “Similarly, with our Space Based Infrared System, SBIRS, one cheap shot creates a hole in our environment. GSSAP will bolster our ability to discern when adversaries attempt to avoid detection and to discover capabilities they may have which might be harmful to our critical assets at these higher altitudes.”

GSSAP will allow more accurate tracking and characterization of man-made orbiting objects, uniquely contribute to timely and accurate orbital predictions, enhance knowledge of the geosynchronous orbit environment, and further enable space flight safety to include satellite collision avoidance.

The GSSAP satellites were covertly developed by Orbital Sciences and the Air Force.

Two additional follow on GSSAP satellites are slated for launch in 2016.

“We must be prepared as a nation to succeed in increasingly complex and contested space and cyber environments, especially in these domains where traditional deterrence theory probably doesn’t apply,” Shelton explained. “We can’t afford to wait … for that catalyzing event that will prod us to action.”

Orion is NASA’s first spaceship designed to carry human crews on long duration flights to deep space destinations beyond low Earth orbit, such as asteroids, the Moon, Mars and beyond.

The inaugural flight of Orion on the unmanned Exploration Flight Test – 1 (EFT-1) mission had been on schedule to blast off from the Florida Space Coast in mid September 2014 atop a Delta 4 Heavy booster, Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told Universe Today during a recent interview at KSC.

The powerful telescopic camera aboard NASA’s Lunar Reconnaissance Orbiter (LRO) has captured spectacular new images detailing the traverse of China’s Yutu moon rover around the landing site during its first two months exploring the Moon’s pockmarked grey terrain.

The newly released high resolution LRO images even show Yutu’s tracks cutting into the lunar surface as the world famous Chinese robot drove in a clockwise direction around the Chang’e-3 lander that delivered it to the ground in mid-December 2013.

You can precisely follow Yutu’s movements over time – from ‘above and below’ – in our new composite view (shown above) combining the latest LRO image with our timelapse mosaic showing the rover’s history making path from the touchdown point last December to today’s location.

Yutu is China’s first ever Moon rover and successfully accomplished a soft landing on the Moon on Dec. 14, 2013, piggybacked atop the Chang’e-3 mothership lander.

Barely seven hours after touchdown, the six wheeled moon buggy drove down a pair of ramps onto the desolate gray plains of the lunar surface at Mare Imbrium (Sea of Rains) covered by volcanic material.

Altogether three images of the rover and lander have been taken to date by the Lunar Reconnaissance Orbiter Camera (LROC) aboard LRO – specifically the hi res narrow angle camera (NAC).

The LROC NAC images were captured on Dec. 25, 2013, Jan. 21, 2014 and Feb. 17, 2014 as LRO soared overhead.

The four image LRO composite below includes a pre-landing image taken on June 30, 2013.

Since the solar incidence angles were different, the local topography and reflectance changes between images showing different levels of details.

“In the case of the Chang’e 3 site, with the sun higher in the sky one can now see the rover Yutu’s tracks (in the February image),” wrote Mark Robinson, Principal Investigator for the LROC camera in an LRO update.

The solar powered rover and lander can only operate during periods of lunar daylight, which last 14 days each.

During each lunar night, they both must power down and enter hibernate mode since there is no sunlight available to generate power and no communications are possible with Earth.

Here is a gif animation from the NASA LRO team combining all four LROC images.

During Lunar Day 1, Yutu drove down the landers ramps and moved around the right side in a clockwise direction.

By the end of the first lunar day, Yutu had driven to a position about 30 meters (100 feet) south of the Chang’e-3 lander, based on the imagery.

After awakening for Lunar Day 2, Yutu then moved northwest and parked about 17 meters (56 feet) southwest of the lander, according to Robinson.

By comparing the Janaury and February images “it is apparent that Yutu did not move appreciably from the January location,” said Robinson.

At this moment Yutu and the companion Chang’e-3 lander are sleeping through their 3rd Lunar Night.

They entered hibernation mode on Feb. 22 and Feb. 23, 2014 respectively.

Hopefully both probes will awaken from their slumber sometime in the next week when the Moon again basks in daylight glow to begin a 4th day of lunar surface science operations.

“We all wish it would be able to wake up again,” said Ye Peijian, chief scientist of the Chang’e-3 program, according to CCTV, China’s state run broadcaster.

However, the hugely popular ‘Yutu’ rover is still suffering from an inability to maneuver its life giving solar panels. It is also unable to move – as I reported here.

The 140 kg rover is now nearing its planned 3 month long life expectancy on a moon roving expedition to investigate the moon’s surface composition and natural resources.
