‘Enterprise’, the first of NASA’s Space Shuttle orbiters to be assembled, was unveiled 35 Years ago on Sept. 17, 1976 to the soaring theme song and fanfare of the immortal science fiction television series – ‘Star Trek’. Members of the original cast (photo above) were on hand for the celebratory rollout at the Rockwell International manufacturing plant in Palmdale, California.

Today, the Enterprise is housed as the centerpiece at the Smithsonian’s National Air & Space Museum (NASM) Udvar-Hazy Annex in Chantilly, Virginia.

NASA originally selected ‘Constitution’ as the orbiter’s name – in honor of the U.S. Constitution’s Bicentennial . That was until avid fans of ‘Star Trek’ mounted a successful letter writing campaign urging the White House to select the name ‘Enterprise’ – in honor of the popular TV shows starship of exploration. The rest is history.

Many scientists and space enthusiasts found inspiration from Star Trek and were motivated to become professional researchers by the groundbreaking science fiction show.

Enterprise was a prototype orbiter, designated as OV-101, and not built for spaceflight because it lacked the three space shuttle main engines necessary for launch and the thermal protection systems required for reentry into the Earth’s atmosphere.

Enterprise did however play a very key role in preparing NASA’s other shuttles for eventual spaceflight. The orbiter was tested in free flight when it was released from a Boeing 747 Shuttle Carrier Aircraft for a series of five critical approach and landing tests in 1977.I was fortunate to see Enterprise back in 1977 on top of a 747 during a cross country stop near the Johnson Space Center.

In 1979 Enterprise was mated to an External Tank and a pair of Solid Rocket Boosters for several weeks of fit checks and procedural test practice in launch configuration at Launch Complex 39 at NASA’s Kennedy Space Center in Florida.

These efforts helped pave the way for the first ever flight of a space shuttle by her sister orbiter ‘Columbia’ on the STS-1 mission by John Young and Bob Crippen. Columbia blasted off on April 12, 1981 on a gutsy 54 hour test flight.

In 1984, the Enterprise was ferried to Vandenberg Air Force Base for similar pad configuration checks at Space Launch Complex- 6 (SLC-6) for what was then planned to be the shuttle’s west coast launch site. All California launches were cancelled following the destruction of Space Shuttle Challanger in Jan 1986.

After three decades of flight, the Space Shuttle Era came to a historic end with the majestic predawn touchdown of Space Shuttle Atlantis on Jul 21, 2011. The STS-135 mission was the Grand Finale of NASA’s three decade long Shuttle program.

Following the retirement of all three remaining shuttle orbiters, Enterprise will soon be moved to her new permanent home at the Intrepid Air, Sea and Space Museum in New York City to make way for NASA’s new gift of Space Shuttle Discovery.

First Appearance of Enterprise
Space shuttle Enterprise made its first appearance mated to supportive propellant containers/boosters cluster, as it was rolled from the Vehicle Assembly Building at Kennedy Space Center en route to the launch pad, some 3.5 miles away, on May 1, 1979. Enterprise underwent several weeks of fit and function checks on the pad in preparation for STS-1, on which its sister craft Columbia took astronauts John Young and Robert Crippen into space for a 54-hour test mission.

Space Spectacular — Rotation Movies of Vesta

Viewing the South Pole of Vesta. This image obtained by Dawns framing camera and shows the south pole of the giant asteroid Vesta. Scientists are discussing whether the circular structure that covers most of this image originated by a collision with another asteroid, or by internal processes early in the asteroid's history. Images in higher resolution from Dawn's lowered orbit might help answer that question. The image was recorded from a distance of about 1,700 miles (2,700 kilometers). The image resolution is about 260 meters per pixel. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

Take us into orbit Mr. Sulu!

The Dawn science team has released two spectacular rotation movies of the entire globe of the giant asteroid Vesta. The flyover videos give the distinct impression that you are standing on the bridge of the Starship Enterprise and gazing at the view screen as the ship enters orbit about a new planet for the first time and are about to begin an exciting new journey of exploration and discovery of the body you’re looking at below.

Thanks to NASA, DLR, ASI and Dawn’s international science and engineering team, we can all join the away team on the expedition to unveil Vesta’s alluring secrets.

Click the start button and watch protoplanet Vesta’s striking surface moving beneath from the perspective of Dawn flying above – in the initial survey orbit at an altitude of 2700 kilometers (1700 miles). Vesta is the second most massive object in the main asteroid belt and Dawn’s first scientific conquest.

Another video below was compiled from images taken earlier on July 24, 2011 from a higher altitude after Dawn first achieved orbit about Vesta and revealed that the northern and southern hemispheres are totally different.

The array of images in the videos was snapped by Dawn’s framing camera which was provided by the German Aerospace Center (DLR). The team then created a shape model from the images, according to Dr. Carol Raymond, Dawn’s Deputy Principal Investigator from NASA’s Jet Propulsion Laboratory in Pasadena, Calif.

The shape model will aid in studying Vesta’s strikingly diverse features of mountains, ridges, valley’s, scarps, cliffs, grooves, craters, even a ‘snowman’ and much more.

Notice that not all of Vesta is illuminated – because it’s northern winter at the asteroid. Vesta has seasons like Earth and the northern polar region in now in perpetual darkness. Data is collected over the day side and radioed back to Earth over the night side.

“On Vesta right now, the southern hemisphere is facing the sun, so everywhere between about 52 degrees north latitude and the north pole is in a long night,” says Dr. Rayman, Dawn’s Chief Engineer from JPL. “That ten percent of the surface is presently impossible to see. Because Dawn will stay in orbit around Vesta as together they travel around the sun, in 2012 it will be able to see some of this hidden scenery as the seasons advance.”

Another movie highlight is a thorough look at the gigantic south pole impact basin. The circular feature is several hundred miles wide and may have been created by a cosmic collision eons ago that excavated massive quantities of material and basically left Vesta lacking a south pole.

[/caption]

The massive feature was discovered in images taken by the Hubble Space Telescope several years ago and mission scientists have been eager to study it up close in a way that’s only possible from orbit. Dawn’s three science instruments will investigate the south pole depression in detail by collecting high resolution images and spectra which may reveal the interior composition of Vesta.

Dawn entered the survey orbit on Aug. 11 and completed seven revolutions of 69 hours each on Sept. 1. It transmitted more than 2,800 pictures from the DLR framing camera covering the entire illuminated surface and also collected over three million visible and infrared spectra from the VIR spectrometer – provided by ASI, the Italian Space Agency. This results exceeded the mission objectives.

The Dawn spacecraft is now spiraling down closer using its ion propulsion system to the next mapping orbit – known as HAMO – four times closer than the survey orbit and only some 680 km (420 miles) above the surface.

Check out this gorgeous new portrait of a Saturnian moon quintet taken by Earths’ emissary – NASA’s Cassini Orbiter. The moons are majestically poised along a backdrop of Saturn’s rings, fit for an artist’s canvas.

Janus, Pandora, Enceladus, Mimas and Rhea are nearly lined up (from left to right) in this view acquired by Cassini at a distance of approximately 684,000 miles (1.1 million kilometers) from Rhea and 1.1 million miles (1.8 million kilometers) from Enceladus.

The newly released image was taken by Cassini’s narrow angle camera on July 29, 2011. Image scale is about 4 miles (7 kilometers) per pixel on Rhea and 7 miles (11 kilometers) per pixel on Enceladus.

Cassini will stage a close flyby of Enceledus – Satarn’s geyser spewing moon – in about two weeks, swooping within 99 km

Moon Facts from JPL:
Janus (179 kilometers, or 111 miles across) is on the far left. Pandora (81 kilometers, or 50 miles across) orbits between the A ring and the thin F ring near the middle of the image. Brightly reflective Enceladus (504 kilometers, or 313 miles across) appears above the center of the image. Saturn’s second largest moon, Rhea (1,528 kilometers, or 949 miles across), is bisected by the right edge of the image. The smaller moon Mimas (396 kilometers, or 246 miles across) can be seen beyond Rhea also on the right side of the image.

This view looks toward the northern, sunlit side of the rings from just above the ring plane. Rhea is closest to Cassini here. The rings are beyond Rhea and Mimas. Enceladus is beyond the rings.

The simple graphic below shows dozens of Saturn’s moons – not to scale. So far 62 have been discovered and 53 have been officially named.

Video Caption: Soyuz Trio Lands in Kazakhstan – The Soyuz spacecraft carrying NASA astronaut Ron Garan and his fellow Expedition 28 flight engineers returned safely to Earth on Sept. 16 with a landing on the steppe of Kazakhstan. Garan and cosmonauts Andrey Borisenko, and Alexander Samokutyaev had been on the International Space Station since April 6. Their journey home was delayed just over a week by the failure of the Progress 44 cargo craft to reach the station. Remaining on the orbiting laboratory is NASA’s Mike Fossum and his two Expedition 28/29 colleagues, Russian Sergei Volkov, and Satoshi Furukawa of the Japanese Aerospace Exploration Agency

Check out this collection of dramatic videos of the departure, descent and safe touchdown of the trio of Russian and American space flyers aboard the Soyuz TMA 21 spacecraft in the remote steppes of Kazakhstan on Sept. 16, 2011.

The first video above is a compilation of all the key events from the Soyuz spacecraft undocking from the International Space Station (ISS) to landing and gives the complete picture. Be sure to watch the Soyuz flying away like a bird with the gorgeous Earth in the background. Observe the crew being extracted like fish from the capsule.

The rest of the videos are shorter and break down the story to focus on the key individual events of the crews remaining final hours aboard the station and in space.

Expedition 28 Soyuz Crew Lands Safely in Kazakhstan

Expedition 28 Lands. The Soyuz TMA-21 spacecraft is seen as it lands with Expedition 28 Commander Andrey Borisenko, and Flight Engineers Ron Garan, and Alexander Samokutyaev in a remote area outside of the town of Zhezkazgan, Kazakhstan, on Friday, Sept. 16, 2011.

The three man Soyuz TMA-21 crew of cosmonauts and astronauts comprising of Commander Alexander Samokutyaev, Expedition 28 commander Andrey Borisenko and NASA flight engineer Ronald Garan made a pinpoint landing following a flawless descent and touched down safely in the southern steppes of Kazakhstan at 12:00 AM EDT today, Sept. 16, (10 AM local time), thereby wrapping up a nearly six month tour of duty at the International Space Station.

The Soyuz capsule landed on its side as it is frequently wont to do, about three hours after sunrise. The soft landing engines fired within seconds of touchdown to cushion the shock.

Weather was perfect with very low winds, few clouds and warm temperatures of nearly 70 degrees Fahrenheit.

Altogether the trio spent 164 days in space, 162 of those were aboard the ISS. Their Soyuz capsule had docked at the ISS on April 7, 2011 following a two day trip after liftoff on April 5 from the Baikonur Cosmodome aboard a capsule dubbed Gagarin. The spaceship was named in honor of Yuri Gagarin, first human to orbit the Earth on the 50th anniversary of his courageous one orbit flight in April 1961 that inaugurated the Era of human spaceflight.

This crew lived aboard the ISS for the arrival of the final two history making flights of the Space Shuttle program as well as the anniversaries of Gagarin and America’s first astronaut in space, Alan Shepard.

Soyuz TMA 21 undocks from the ISS.

The helicopter recovery team arrived at the Soyuz capsule with seconds of touchdown and began erection of an inflatable medical tent. The Soyuz was rolled to facilitate the safe and proper extraction of the crew.

The astronauts and cosmonauts were quickly extracted from the capsule by the ground crew, checked by doctors and placed in recliners for the two hour trip back to a staging base in Karaganda, Kazakhstan for a traditional Kazakh welcome. Thereafter the crew will split up. Garan will be returning immediately to the US on a flight back to the Mission Control in Houston, Texas.

Soyuz departs

Just hours earlier this evening, the trio bagan the process of departing the ISS. They donned their Sokol launch and entry pressure suits, floated into the return capsule and closed the hatches between the Soyuz and the ISS.

Following leak checks the crew unhooked latches and undocked the Soyuz from the Poisk module at 8:38 p.m. while flying over northern China. Three minutes later thrusters were fired for 15 seconds to separate the two vehicles.

Left behind on the station was the Expedition 29 crew comprising Commander Mike Fossum from the US, cosmonaut Sergei Volkov from Russia and Japanese astronaut Satoshi Furukawa.

As the ISS and Soyuz were flying in tandem, the crew executed the 4 minutes 14 sec “de-orbit burn” which took place exactly on time at 11: 05 p.m. EDT. The critical Soyuz thruster burn slowed the ship by some 258 MPH and enabled the capsule to drop out of orbit, setting up the descent down through the Earth’s atmosphere.

Then the computer commanded pyrotechnic separation of the three Soyuz modules took place some 87 miles above Earth about 22 minutes later at 11:33 p.m., occurring just three minutes prior to re-entry into the Earth’s atmosphere over the heart of Africa.

The crew landed inside the central descent module less than an hour after completing the burn and less than 30 minutes after module separation.

The ISS will now be tended by only a three man crew for the next two months. That’s an unusually long time to maintain a reduced crew. But it’s all due to the recent failure of the third stage of the Russian Soyuz-U rocket lofting the Progress 44 cargo ship on Aug 24. The failure has been traced to a clogged fuel line. Russia is working to determine exactly how and why this could have happened and taking steps to prevent a repeat which would have disastrous consequences.

The next Soyuz blastoff is provisionally set for Nov.14 with a station arrival on Nov. 16. The three man crew of Anton Shkaplerov, Anatoly Ivanishin and NASA flight engineer Dan Burbank had originally been slated for Sept 22. But it was pushed back following the Progress launch failure.

Mike Fossom’s crew is scheduled to depart just 2 days later. Thus any further Soyuz launch delay wil require the ISS to be at least temporarily “de-manned” for the first time since continuous crewed operations started a dozen years ago.

Check out our gallery of more thrilling launch photos of NASA’s twin GRAIL spacecraft departing Earth on Saturday, Sept. 10 at 9:08 a.m. EDT from Pad 17B at Cape Canaveral Air Force Station in Florida.

Although GRAIL’s liftoff was delayed a few days by excessively high upper level winds, it was well worth the wait and put on a spectacular show as the booster thundered away from Space Launch Complex 17. This Delta II rocket was almost certainly the last ever Delta to blastf off from the Florida Space Coast.

On this somber occasion marking the 10th anniversary of the tragic events of 9/11, NASA’s Opportunity Mars rover has taken new images of itself on 9/11/11 showing a piece of metal recovered from the wreckage of the Twin Towers of the World Trade Center in New York City that was carried all the way to the planet Mars as a commemorative memorial to the innocent victims of the terrorist attacks of Sept 11, 2001.

On Sept. 11, 2011 (Martian Sol 2713), Opportunity snapped the memorial image above showing the Rock Abrasion Tool (RAT) and an American Flag – evoking the memory of the Twin Towers – from a slope on a Martian hill named Cape York which in turn is a segment of the rim of a gigantic crater named Endeavour.

Opportunity is still roving the red planet’s surface, nearly 8 years after safely landing on Jan 24, 2004. After an epic trek she recently arrived at the gigantic 14 mile wide Endeavour crater .

Opportunity took the new image of the RAT and 9/11 US Flag memorial on Mars on the exact day timed to coincide with the 10th anniversary of the attacks.

The image shows the arm extended for inspection of target on a rock called “Chester Lake”, according to NASA officials. Opportunity is driving in a northerly direction up the Cape York hill on her scientific expedition of the crater’s rim.

Both towers of the World Trade Center in New York City were destroyed by the terrorists on that terrible day and nearly 3000 precious people were killed during horrifying historic events that changed America and the World forever.

The RAT was built for NASA and both rovers by Honeybee Robotics which at that time was located less than a mile away from the WTC near the southern tip of Manhattan.

Steve Gorevan, the founder and chairman of Honeybee and a member of the rover science team, told me in a past interview that he was on his way to work and out on the city streets within a few blocks of the Twin Towers when he suddenly heard the sounds of the jet engines just before the first tower was struck.

Gorevan and the Honeybee employees watched the tragic events unfold from their company’s offices and rooftop the rest of the day. Following the terror attacks, Gorevan said access to Honeybee was restricted for weeks and the firm was on a tight deadline to deliver the RAT’s to NASA and the Jet Propulsion Laboratory in California where the rovers were being assembled.

The idea for somehow placing a Martian memorial on the rovers was presented. Gorevan told me that he was able to secure metallic pieces from the WTC wreckage through the Office of the then NYC Mayor Rudy Guiliani a few weeks after the attacks.

Aluminum shards were delivered by the Mayor’s office to Honeybee along with a note indicating their authenticity. These were soon fashioned into an aluminum shield that was placed on each RAT along with a US Flag. The shield serves as a cable guard.

Gorevan says the twin towers memorial was purposely kept quiet for some time until well after both rovers landed out of respect for the victims’ families.

Opportunity is healthy and continuing her exploration of Endeavour crater which harbors geologic formations and rocks unlike any previously investigated by either of the Mars Exploration (MER) rovers.

Along the rim of Endeavour crater rover scientists hope to discover and analyze clay minerals which formed in pH neutral water billions of years ago and a habitable environment much more favorable to the formation of life compared to all the other spots studied by either rover thus far.

Both rovers far exceeded their original 90 days warranties with many years of added bonus time for science exploration.

Video caption: NASA’s twin GRAIL spacecraft blast off atop a Delta II Heavy booster at 9:08 a.m. EDT on Saturday, September 10, 2011 from Cape Canaveral, Florida, on a mission to explore the moon in unprecedented detail.

Be sure to check out these awesome launch videos showing the Delta II Heavy rocket blasting off with NASA’s GRAIL Lunar Gravity Mapper twins on a “Journey to the Center of the Moon” – as shot by NASA and others – on Sept. 10. from Pad 17 B at Cape Canaveral Air Force Station in Florida at 9:08 a.m. EDT.

Thus began a circuitous 3.5 month voyage from the Earth to the Moon culminating in lunar orbit arrival on New Year’s Eve and Day 2012.

[/caption]
Liftoff of the $496 Million Gravity Recovery and Interior Laboratory (GRAIL) duo marked the last currently scheduled launch of a United Launch Alliance Delta II from Florida and also the last launch from Space Launch Complex 17. This was the 356th Delta launch overall since the first one in 1960. It was the 110th and final planned flight of a Delta II from Florida.

Watch the NASA GRAIL Launch Video as the 12 story Delta’s 1st stage liquid and solid engines ignite and the rocket’s explosive exhaust and fiery flames instantaneously and dramatically shoot out from below and are vented safely to the side through specially constructed flame ducts to protect the rocket.

Just after the 1 minute mark, the 6 ground lit solid rocket motors are jettisoned and dramatically tumble away from the first stage. Moment later comes the ignition of the three air-lit solid rocket motors.

This dramatic video was shot by Matt Travis of spacearium -from my viewing location with a hoard of photojournalists at Press Site 1 located inside Cape Canaveral Air Force Station.

Press Site 1 is just 1.5 miles away from Pad 17B. It offers the closest and best view of the mighty Delta II rocket which stands 128 feet tall and generates some 1.3 million pounds of liftoff thrust.

Watch this video for post-launch commentary from NASA’s Delta II Launch manager Tim Dunn from the Mission Director’s Center.

The GRAIL Launch video below was taken from Jetty Park Pier, about 2.9 miles south of Pad 17B and shows a completely different perspective from across the waterway of Port Canaveral.

I watched the unforgettable launch of Dawn five years ago from Jetty Park Pier.

Jetty Park and the beaches along Cape Banaveral and Cocoa Beach have been the best place for the public to view Delta rocket launches.


Thousands of spectators lining the Florida Space Coast were absolutely thrilled to witness the historic launch of GRAIL on the final Delta II booster from Florida on a gorgeous morning.

GRAIL’s primary science objectives during the 82 day mission are to determine the structure of the lunar interior, from crust to core, and to advance understanding of the thermal evolution of the moon and apply that to the other rocky bodies in our solar system.

Check this short NewBlast Video summary of GRAIL’s launch and objectives from Spaceflight Now

Many of NASA’s recent science missions have launched aboard Delta II rockets, including the outstandingly successful Spirit and Opportunity Mars rovers, Dawn Asteroid Orbiter, MESSENGER Mercury orbiter and Stardust and Deep Impact comet spacecraft.

NASA renewed its focus on ground breaking science today with the thunderous blastoff of a pair of lunar bound spacecraft that will map the moons interior with unparalled precision and which will fundamentally alter our understanding of how the moon and other rocky bodies in our solar system – including Earth – formed and evolved over 4.5 Billion years.

Today’s (Sept. 10) launch of the twin lunar Gravity Recovery and Interior Laboratory (GRAIL) spacecraft atop the mightiest Delta II rocket from Cape Canaveral Air Force Station in Florida at 9:08 a.m. EDT was a nail biter to the end, coming after a two day weather delay due to excessively high upper level winds that scrubbed the first launch attempt on Sept. 8, and nearly forced a repeat cancellation this morning.

Liftoff of the nearly identical GRAIL A and B lunar gravity mappers from Space Launch Complex 17B took place on the second of two possible launch attempts after the first attempt was again waived off because the winds again violated the launch constraints.

After the final “GO” was given, the Delta II Heavy booster suddenly roared to life and put on a spectacular show spewing smoke, flames and ash as it pushed off the pad and shot skywards atop a rapidly growing plume of exhaust and rumbling thunder into a nearly cloudless sky.

The solar powered dynamic duo were propelled to space by the last ever Delta II rocket slated to depart Earth from Cape Canaveral, Florida. After more than 50 years of highly reliable service starting in 1960, the venerable Delta II family will be retired after one final launch in October from Vandenberg Air Force Base in California.

On this special occasion the media were allowed to a witness the launch from Press Site 1 – a location just 1.5 miles away from the pad with a gorgeous and unobstructed view to the base of the pad which magnified the tremendous roar of the rocket engines.

“Since the earliest humans looked skyward, they have been fascinated by the moon,” said GRAIL principal investigator Maria Zuber from the Massachusetts Institute of Technology in Cambridge. “GRAIL will take lunar exploration to a new level, providing an unprecedented characterization of the moon’s interior that will advance understanding of how the moon formed and evolved.”

The spacecraft separation and deployment of the solar arrays worked exactly as planned, the mission team reported at a post launch briefing for reporters. Both probes are power positive and healthy.

GRAIL A and B are now speeding towards the moon on a low energy path that will take about 3.5 months compared to just three days for the Apollo astronauts. The slower and longer path covering more than 2.5 million miles (4 million kilometers) enables the spacecraft to use a smaller engine and carry less fuel for the braking maneuver required to place the probes into a polar elliptical orbit when they arrive at the moon about 25 hours apart on New Year’s Eve and New Year’s Day 2012.

“Our GRAIL twins have Earth in their rearview mirrors and the moon in their sights,” said David Lehman, GRAIL project manager at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif. “The mission team is ready to test, analyze and fine-tune our spacecraft over the next three-and-a-half months on our journey to lunar orbit.”

During the 82 day science phase, the primary objective of is to study the moons interior from crust to core and map its gravity field by 100 to 1000 times better than ever before. GRAIL A and GRAIL B will fly in tandem formation in near circular polar orbit at an altitude of some 50 km above the lunar surface as the moon rotates beneath three times.

The mission will provide unprecedented insight into the structure and composition of moon from crust to core, unlock the mysteries of the lunar interior and advance our understanding of the thermal evolution of the moon that can be applied to the other terrestrial planets in our solar system, including Mercury, Venus, Earth and Mars.

GRAIL Unveiled for Lunar Science Trek — Launch Reset to Sept. 10

NASA’s Gravity Recovery and Interior Laboratory (GRAIL) moon mapping twins and the mighty Delta II rocket that will blast the high tech physics experiment to space on a lunar science trek were magnificently unveiled in the overnight darkness in anticipation of a liftoff that had originally been planned for the morning of Sept. 8.

Excessively high upper level winds ultimately thwarted Thursday’s launch attempt.

NASA late today has just announced a further postponement by another day to Saturday Sept. 10 to allow engineers additional time to review propulsion system data from Thursday’s detanking operation after the launch attempt was scrubbed to Friday. Additional time is needed by the launch team to review the pertinent data to ensure a safe blastoff of the $496 Million GRAIL mission.

There are two instantaneous launch opportunities at 8:29:45 a.m. and 9:08:52 a.m. EDT at Cape Canaveral, eight minutes earlier than was planned on Sept. 8. The weather forecast for Sept. 10 still shows a 60 percent chance of favorable conditions for a launch attempt.

Despite a rather poor weather prognosis, the heavy space coast cloud cover had almost completely cleared out in the final hours before launch, the surface winds were quite calm and we all expected to witness a thunderous liftoff. But measurements from weather balloons sent aloft indicated that the upper level winds were “red” and violated the launch criteria.

As the launch gantry was quickly retracted at Launch Complex 17B on Sept. 7, the Delta was bathed in xenon spotlights that provided a breathtaking light show as the service structure moved a few hundred feet along rails.

The cocoon like Mobile Service Tower (MST) provides platforms to access the rocket at multiple levels to prepare the vehicle and spacecraft for flight. The MST also protects the rocket from weather and impacts from foreign debris.

The GRAIL A and B mirror image twins ride side by side to space atop the Delta rocket. The washing machine spacecraft weigh about 677 pounds (307 kg) each.

The Delta II rocket stands 128 feet tall and is 8 feet in diameter. The first stage liquid and solid rocket fueled engines will generate about 1.3 million pounds of thrust.

During the Terminal Countdown, the first stage is fueled with cryogenic liquid oxygen and highly refined kerosene (RP-1).

GRAIL is an extraordinary first ever journey to the center of the moon that will — with its instruments from orbit — peer into the moons interior from crust to core and map its gravity field by 100 to 1000 times better than ever before. The mission employs two satellites flying in tandem formation some 50 km in near circular polar orbit above the lunar surface.

GRAIL A and B will perform high precision range-rate measurements between them using a Ka-band instrument. The mission will provide unprecedented insight into the formation and thermal evolution of the moon that can be applied to the other rocky planets in our solar system: Mercury, Venus, Earth and Mars.

After a 3.5 month journey to the moon, the probes will arrive about a day apart on New Year’s Eve and New Year’s Day 2012 for an 82 day science mapping phase as the moon rotates three times beneath the GRAIL orbit.
