With just over 6 weeks to go until the liftoff of Curiosity – NASA’s next Mars rover – prelaunch processing at the Kennedy Space Center (KSC) in Florida is rapidly entering the home stretch. Technicians placed the folded rover inside the complete aeroshell to match the Martian entry configuration components together and conduct preflight testing of the integrated assembly at the Payload Hazardous Servicing Facility at KSC. The aeroshell is comprised of the heat shield and back shell and encapsulates Curiosity during the long voyage to Mars.
The job of the aeroshell is to protect the Curiosity Mars Science Laboratory (MSL) from the intense heat of several thousand degrees F(C) generated by friction as the delicate assemblage smashes into the Martian atmosphere during the terrifying entry and descent to the surface.
The rover itself has been mated to the back shell powered descent vehicle, known as the PDV or sky crane. The rocket powered descent stage (PDV) is designed to maneuver through the Martian atmosphere, slow the descent and safely set Curiosity down onto the surface at a precise location inside the chosen landing site of Gale Crater.
Technicians still have several more weeks of hardware testing and planetary protection checks ahead before NASA’s minivan sized Martian robot is encapsulated inside the aeroshell for the final time.
Another major task still to be completed is mating the aeroshell to the cruise stage and then fueling of the cruise stage, which guides MSL from the Earth to Mars, according to Guy Webster, press spokesman for NASA’s Jet Propulsion Laboratory which manages the MSL project for NASA.
The launch of the $2.5 Billion Curiosity rover atop an Atlas V rocket is slated for Nov. 25, the day after Thanksgiving, and the launch window extends until Dec. 18. Arrival at Gale crater is set for August 2012.
Curiosity is by far the most scientifically advanced surface robotic rover ever sent beyond Earth and will search for environmental conditions that could have been favorable to support Martian microbial life forms if they ever existed in the past or present.
‘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.
Check out these webcams for live views of shuttle Enterprise at NASM from the front and aft.
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.

Following the majestic predawn touchdown of Space Shuttle Atlantis at the Kennedy Space Center (KSC) to close out the Space Shuttle Era, the final crew of Atlantis, NASA Administrator Charles Bolden and KSC Director Bob Cabana thanked the Space Shuttle workforce for their dedication and hard work at an employee appreciation event held outside the processing hangers where the orbiters were prepared for the 135 shuttle missions flown by NASA over more than thirty years.
The four person crew of Atlantis on the STS-135 mission flew a special commemorative banner millions of miles to the International Space Station and back in honor of the thousands of workers who processed, launched and landed America’s five space shuttles. They unfurled the banner at the employee event at KSC in tribute to the shuttle workers.
“It’s great to be here in sunny Florida,” said STS 135 Commander Chris Ferguson. “Mike Leinbach [ the Space Shuttle Launch Director] said there was no way he’d let us land in California.”
“We want to express our gratitude on behalf of the astronaut office for everything you have done here at KSC, the safety you have built into the vehicles, the meticulous care that you take of the orbiter. As soon as we got on orbit, I was absolutely amazed that everything in Atlantis works so well. Everything looks beautiful on the inside.”
“I hope you all believe that every time we go, we take a little bit of every one of you with us,” Ferguson emphasized.
Atlantis was parked at the event as a backdrop for photo opportunities with the thousands of shuttle workers in attendance – along with over a hundred journalists including the Universe Today team of Alan Walters and Ken Kremer.
“Like Chris said, our one landing option was getting back to Florida and you all rather than anywhere else. It felt like being home again. Thank you for everything you have all done over the last 30+ years,” said Doug Hurley.
“We treated Atlantis with the utmost respect because we see firsthand how you process this vehicle and it is your baby,” said Rex Waldheim. “It is clean and well cared for. We did that for you because you all did such a great job preparing it for us.”
“You are such a special work force,” added Sandy Magnus. “There is no workforce like the space program workforce anywhere in the world. The pride, care, dedication and passion you take in your work is what makes it possible to have these very challenging missions and to succeed. You have to do everything right all of the time. And you DO. And you make it look easy!! Congratulations!”
The STS-135 crew then unfurled the colorful banner taken to the ISS aboard Atlantis to commemorate NASA’s Space Shuttle Era.
“We took this banner with us to space and this is our way of telling you that you guys rock ! We will present this to Mike Leinbach and Bob Cabana as just a small token of our appreciation for all the work you’ve done for us. Thank you for such a wonderful vehicle,” Ferguson summed up.
The crew then waved good bye to the thousands of shuttle workers, posed with Atlantis one last time and departed with their families for a homecoming celebration at their training base at the Johnson Space Center in Houston, Texas.
Atlantis was then towed a few hundred yards (meters) and came to rest inside the Orbiter Processing Facility to conclude her final spaceflight journey as the last of NASA’s flight worthy Space Shuttle Orbiters. She has began decommissioning activities due to last several months to prepare for her future retirement home at the Kennedy Space Center Visitor Complex (KSCVC) just a few miles (km) away.
Atlantis permanent new abode at KSCVC is set to open in 2013 where she will be genuinely displayed bearing scorch marks from reentry and as though “In Flight” with payload bays doors wide open for the general public to experience reality up close.
For some 1500 shuttle workers, the day’s proceedings were both joyous and bittersweet – as their last full day of employment and last chance to bask in the glow of the triumphant conclusion of the Shuttle Era.
At Wheels Stop with Atlantis ! Here ended the Shuttle Era
A few short hours after the touchdown of Space Shuttle Atlantis closed out NASA’s Space Shuttle Era, myself and a small group of extremely lucky journalists and photographers were invited by NASA to journey to ‘Wheels Stop’ – Runway 15 at the Shuttle Landing Facility at the Kennedy Space Center for a thrilling and once in a lifetime eyewitness experience to the exact spot where Atlantis rolled to a stop.
After 30 years and 135 missions, the landing of the Final Flight of Space Shuttle Atlantis on July 21, 2011 at 5:57 a.m. concluded America’s Space Shuttle Program. The Grand Finale was commemorated with banners, quilts and celebrations at Runway 15.
The STS-135 crew comprised of Shuttle Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim.
It’s truly an honor and a privilege to be granted this extremely rare and magnificent opportunity to witness history first hand by the folks at NASA and the Kennedy Space Center – and share this with the public. Thank you !

Videographers David Gonzales, Kurt Johnson and Mike Deep filmed the final launch of the Space Shuttle from the Kennedy Space Center Press Site. The team used multiple cameras along with a high definition stereo audio recording device to capture the sights and sounds as Atlantis thundered into orbit. The goal was to provide the closest launch experience for the viewer without actually being there.
A Space Shuttle launch is a spectacle that will never again be seen. The sequence begins with a tight shot of the pad in the final seconds of the count. As the 3 Space Shuttle Main Engines ignite they flash water from the sound suppression water system into steam, sending a plume billowing away. The entire stack rocks a couple of feet before settling back vertical. The Solid Rocket boosters ignite, launching out a second plume and lifting the 4.5 million pound stack off the ground. Spectators erupt into cheers and the shutters of thousands of press cameras click away.
Photographers David Gonzales and Mike Deep shot this footage from the Kennedy Space Center Press Site for Universe Today of the final launch of NASA’s Space Shuttle Endeavour. See the launch approximately 27 times as fast, (don’t blink — you might miss it!) and watch how the smokey plume changes over time as it is tugged on by wind and casts a changing shadow on the cloud deck below.

KENNEDY SPACE CENTER – NASA managers set May 16 as the new launch date for the final flight of Space Shuttle Endeavour after technicians completed work to rewire and retest a switchbox in the orbiters aft compartment. Shuttle managers ordered the repair work following a heater malfunction that forced NASA officials to call off the planned April 29 launch.
At a briefing for reporters today (May 9) at NASA’s Kennedy Space Center in Florida, Shuttle managers Mike Moses and Mike Leinbach announced that Endeavour’s last liftoff is now targeted for 8:56 a.m. EDT on Monday, May 16.
“Right now, we’re in good shape,” said Shuttle Launch Director Mike Leinbach.
“Endeavour’s looking good, the team is upbeat. I went to the meeting this morning and they’re ready to go. Hopefully, this time the heaters will work and we’ll be able to launch on time next Monday morning.”
The STS-134 mission is the penultimate flight of the space shuttle program and will deliver the $2 Billion Alpha Magnetic Spectrometer to the International Space Station.
Endeavour’s last launch attempt on April 29 was scrubbed about four hours prior to blastoff when critical hydrazine fuel line heaters failed to turn on inside one of the orbiters three auxiliary power units (APU’s).
Technicians have been working around the clock to resolve the problems and determined that the likely cause of the heater failure was an electrical short inside the ALCA -2 load control assembly box located in the aft section of the shuttle (see photo).
They installed about 20 feet of new wiring, a new ALCA box and then retested all related systems over the past week and a half.
“We’ve replaced everything except the heaters, and we’ve wrung those out with at least five separate checks and full functionals afterwards and now have extremely high confidence that the problem is no longer on the ship or in any of the electronics,” said Mike Moses, the Shuttle launch integration manager at the Kennedy Space Center.
The APU’s control the shuttles hydraulics which power the steering of the main engines, wings, wheels and rudders during ascent and re-entry. The three units must all be fully functional before NASA can commit to any shuttle launch as part of the launch commit criteria (LCC). If the heaters fail during flight, the hydrazine can freeze and clog the fuel lines and render the hydraulics inoperative. A rupture in the lines could result in toxic hydrazine leaking into the shuttles aft engine compartment.
The potential launch window for Endeavour’s final flight extends through May 26, except for May 21.
The all veteran six man crew led by Shuttle Commander Mark Kelly is due to fly to the Cape on Thursday, May 12 from their training base in Houston. The STS-134 mission has been officially extended to 16 days from 14 days and will include 4 spacewalks.
The launch countdown will commence on Friday, May 13 from the beginning of the nominal 41 hour countdown sequence.
As a consequence of Endeavour’s delays, the launch of the very final shuttle mission of Space Shuttle Atlantis will likely be delayed to mid-July, although Moses and Leinbach did not give a specific target date.
KENNEDY SPACE CENTER – A large brush fire suddenly broke out this today (April 27) less than 1 mile fom the Kennedy Space Center (KSC) Press Site in the midst of the countdown to Space Shuttle Endeavour’s last launch, set for this Friday, April 29.
Huge plumes of billowing smoke were sent skyward over the spaceport starting around 1 p.m. from the fires and were spread out over more than 100 acres. The fires erupted at some distance behind the NASA Tweeters tent erected at the press site and were located just 3 miles from the shuttle launch pad. The cause of the fires is unknown but occurred after a long spell of dry weather at KSC.
Helicopters and NASA Firefighters were called in to put out the fires. Fire trucks careened past the countdown clock towards the nearby fire. The helicopters flew back and forth all afternoon dumping buckets of seawater onto the wildfires trying to bring it under control.
“The shuttle launch pad was never in any danger due to the Turn basin in between and it hasn’t impacted any launch operations,” KSC spokesman Allard Beutel told Universe Today.
The Universe Today team of Alan Walters and Ken Kremer witnessed the spectacular and potentially frightening scene first hand and onsite.
It looked like Armageddon all afternoon long and was finally contained tonight. Nothing like this ever occurred so close to a launch and its not clear if the fire would have caused a scrub on launch day. Check out our up close photo album.

‘In Flight’ …. That’s the heart of the dramatic plan to showcase a Space Shuttle Orbiter being proposed by the Kennedy Space Center Visitor Complex (KSCVC) as they seek to win the heated competition to become the permanent new home to one of NASA’s three soon to be retiredOrbiters.
Honoring the past, embracing the future of human spaceflight and celebrating the spirit of human determination; this is the new theme planned by the Visitor Complex at Kennedy so that guests of all ages will feel like they are embarking on an interactive space expedition. See the ‘In Flight’ graphic illustration above.
Some 21 science centers and museums across the US are bidding for the once in a lifetime chance to house NASA’s surviving shuttle orbiters; Discovery, Atlantis and Endeavour.
“The Kennedy Space Center is the home of the Space Shuttle unlike all the other places,” said Bill Moore, Chief Operating Officer of KSCVC. I spoke to Moore at KSC in an exclusive interview for Universe Today.
“All of the shuttle missions have launched from here, not anywhere else. So Kennedy is their home. And they all eventually come back here at the end of each mission. So we have a compelling story to tell about their history at KSC and the future.”
The Smithsonian National Air & Space Museum, Washington, D.C., has long been expected to be picked as the retirement home for Space Shuttle Discovery, the oldest orbiter. That leaves Atlantis and Endeavour remaining in the bidding war. Since the Smithsonian currently displays the shuttle Enterprise, that unflown orbiter would also be up for grabs by another venue.
NASA Administrator Charles Bolden will decide the final site selections. He is scheduled to announce the winner of the nationwide competition on April 12, which is the 30th anniversary of the first shuttle flight (STS-1) by Columbia on April, 12, 1981.
Another location that plays a pivoital role in the U.S. space program is NASA’s Johnson Space Center in Houston, Texas, home to Mission Control. Johnson Space Center is also home base for the shuttle astronauts and houses the facilities where they train for space missions. The Johnson Visitor Center – Space Center Houston – has proposed a 53,000 square foot pavilion with interactive exhibits.
Many of those who work on space projects feel strongly that two of the orbiters should unquestionably be awarded to the Kennedy Space Center (KSC) and the Johnson Space Center JSC) since these are the two locations most intimately involved with the Space Shuttle program. All the crews were trained at JSC and blasted off to space from KSC.
Among the other contenders in the running to house an orbiter are; the Intrepid Sea-Air-Space Museum in New York City; the Adler Planetarium in Chicago; the National Museum of the Air Force in Dayton, Ohio; the U.S. Space & Rocket Center in Huntsville, Alabama; the Museum of Flight in Seattle.
At the Kennedy Visitor Complex, a brand new 64,000 square-foot hall would be constructed to display the orbiter “In Flight”. The exhibit would engage viewers in an up close experience to see how the vehicle actually worked in space and also feature its major accomplishments; such as building the International Space Station (ISS) and upgrading the Hubble Space Telescope.
The orbiter home is projected to cost some $100 million and would be the marquee element of the master plan entailing a transformative overhaul of the entire visitor complex at Kennedy, according to Moore.
The KSCVC concept is outlined in a thick book with extensively detailed story boards and drawings. Clearly, a lot of hard work and thought has gone into designing KSCVC’s proposal to house an orbiter and integrate it with a complete renovation and update of the spaceport tour facilities. The goal is to satisfy the interests of the whole family- not just hard core space geeks.
“We (KSCVC) will display the orbiter tilted, like it is flying in space and at work. Because that’s the way people think about the orbiter – working in space. Not sitting on the ground on three wheels,” Moore explained to me.
“So, our job at KSC is to show the shuttle’s working time as it is flying in space. The payload bay doors will be open and the robotic arm will be extended. Some type of cargo will be inside. We will also show the Hubble and the ISS with models, giant video screens and murals, because we think that’s key to understanding the role of the shuttle.”
Moore told me that this will be the largest building ever constructed at KSCVC, even bigger than the popular Shuttle Launch Experience completed a few years back.
“When people come into the exhibit, their first view will be to see the orbiter as though someone would see it by looking out from the ISS, up against a gorgeous backdrop of the Earth, the Sky and the Universe.”
“The point is to make you believe that you are actually seeing the orbiter in space. Visitors will be able to view the orbiter from many different angles,” said Moore.
The shuttle will be shown as it really looks and is flown with the heat shield tiles, with all its scorch marks, pits, scars and imperfections.
“We do not want the orbiter to be polished to a pristine state,” Moore stated firmly.
“We want to expose as many people as possible from around the world to this wonderful vehicle and to what’s happened up there in space.”
“The vehicle is just part of the story. The story is much bigger.
“The purpose of the display building is that we want to show the whole story of what the shuttle has done and all the major milestones. The people who processed and cared for the orbiters are also part of the story,” Moore amplified.
“We will remember and show the story of those who made the ultimate sacrifice, what we learned from the accidents and then fixed lots of issues to get to a better flight system.”
I asked Moore, when will the exhibit open ? “I would like to open the exhibit by mid to late 2013,” he replied.
The orbiter will be showcased with components from the shuttle’s history. “We have the beanie cap, the white room and a fairly large collection of many other artifacts, parts and items beyond just the orbiter that will be used to tell the story of the shuttle program.”
“The shuttle story covers 30 remarkable years,” said Moore.
Only two flights remain until the shuttles are forcibly retired for lack of many and some say willpower to continue exploring.
The final flight of Endeavour on the STS-134 mission is set for April 19. Atlantis is honored with the shuttle programs very last mission, STS-135, slated for late June 2011.
Discovery just landed on her historic final mission on March 9 – a thrilling and bittersweet experience for all who work and report on the shuttle program. Discovery is being decommissioned and now belongs to history although she has a lot of life left in her.
Stay tuned for the April 12 announcement of the Orbiter homes selected.
