As he looks back over the years, former shuttle astronaut Robert Springer remembers the shuttle era very clearly. He flew on Atlantis – and Discovery. With the final flight of Discovery only a few days away, he took time out of his busy schedule to reminisce about his time ‘riding rockets.’

“Great memories,” Springer said, “I’m really proud of the opportunity I had and the chance to serve my country, and so it was was special — very special.”

Springer received his aviator’s wings in 1966 with the United States Marine Corps. He flew F-4 Phantoms in Vietnam where he also served as an advisor to the South Korean Marine Corps. Springer would fly some 300 combat missions in F-4s and an additional 250 combat missions in O-1 Bird Dogs, UH-1 “Hueys.” Springer would eventually attend navy Fighter Weapons School – known more commonly as “TOPGUN.” Springer has been awarded numerous awards including the Navy Distinguished Flying Cross and the Bronze Star.

He was selected to become an astronaut in 1980, completing training one a year later in 1981. He served on the support crew for STS-3 working on various aspects of the “Canadarm” remote manipulator system. Between 1984 and 1985 he served as CAPCOM on seven shuttle flights. After waiting nine years he flew his first mission in 1989 aboard Discovery on STS-29.

STS-29 was a highly-successful mission that deployed a Tracking and Data Relay Satellite (TDRS) and conducted numerous experiments while on orbit. A year later in 1990 Springer again left Earth for the black sky on STS-38. This mission was aboard Atlantis and was a classified Department of Defense mission. It was the first mission to land at Kennedy Space Center in Florida since 1985. Of the two missions, Springer remembers STS-38 with a bit of a smile.

“My first flight on STS-29 was shortly after the first Return-to-Flight in 1988 and while the media attention was nice, once is enough,” Springer said. “So for STS-38 we were completely cut off from the press – it was fantastic! I just felt kind of bad for the new guys on that flight as they missed that aspect of a shuttle mission.”

When speaking with Springer, you can see the smile fade somewhat when the subject turns to the final flight of Discovery, arguably the most historic of the surviving orbiters.

“It’s going to be a little tough, realizing that this will be the last time that Discovery will be going into space,” Springer said while looking out at Launch Complex 39a. “You know that someday that the program is going to come to an end, but to actually have that take place and come to fruition, while exciting to see it launch – it will be sad.”

He fondly recollected his experience on board Discovery as one of the most amazing experiences in a career that has witnessed some of the most powerful experiences in American history.

“The flight overall was fantastic, it was so incredibly intense,” Springer said with a smile. “We were one of the first flights after the Challenger accident. While we normally plan for a 16 hour day during missions, we were so busy it ended up being an 18 hour day. Whenever we had a free minute we would hog the windows and stare out into space until you couldn’t fight it anymore and you’d drift off to sleep – and around the shuttle cabin.”

The crew for the last mission for space shuttle Discovery spent the week at NASA’s Kennedy Space Center conducting the Terminal Countdown Demonstration Test or as it is more commonly know – TCDT. The crew arrived Tuesday, Oct. 12 and immediately set to work. This week of training is the last major milestone on the path to launch, currently scheduled to take place on Nov. 1 at 4:40 p.m. EDT.

TCDT consists of is training that simulates the final hours up until launch. This provides training for both the crew and the launch team. The launch team practices launch day timelines as well other, crucial flight-day procedures. The crew on the other hand went through a number of exercises that included:

• Rescue training – The astronauts will run through several simulations where they practice what to do in the event of an emergency. The crew will be instructed on how to use the emergency baskets that will allow them to escape the launch pad in case there is a fire. They will also learn how to operate the tank-like M113 personnel carrier and other emergency equipment.
• The commander in pilot will perform abort landings and other flight aspects in the Shuttle Training Aircraft (STA). The plane is a Grumman Gulfstream II and it duplicates the shuttle’s approach profile and many of the orbiter’s handling qualities.
• Conduct a launch day simulation that includes everything that will happen on launch day – except the launch. The crew walked out in their bright orange launch and entry suits. TCDT also includes a simulated abort so that the crew is well-versed as to what do to in case of that scenario.

These activities allow the crew and flight teams to do a rehearsal of all the events that will take place on launch day.

“This is a dress rehearsal for the real flight so the crew is kind of peaked up; they’ve put all the sequence of events together, when they go out to the pad they’ll do everything except igniting the main engines,” said Robert Springer a two-time shuttle veteran. “It’s a chance to review all your procedures and make sure everything is in place.”

The crew of STS-133 consists of Lindsey, Pilot Eric Boe and Mission Specialists, Michael Barratt, Tim Kopra, Alvin Drew and Nicole Stott. The crew is comprised entirely of space flight veterans.

STS-133 is an 11-day mission to the International Space Station (ISS) to deliver the Leonardo Permanent Multipurpose Module (PMM) which contains, among other thing, the first humanoid robot to fly into space – Robonaut-2 (R2). Also onboard is the Express Logistics Carrier-4 and spare parts for the orbiting laboratory.

Springer’s first flight was on space shuttle Discovery and as he watched the crew for her final mission his thoughts reflected on his experiences and the end of the shuttle era.

“It’s going to be a little tough, my personal experiences that I have of Discovery and my memories that I have of that time make it a little bittersweet to realize that this will be the last time that Discovery will go into space.”

Soyuz Launches; Discovery’s Final Payload Delivered to Launch Pad

October 7 was a busy day in spaceflight, as a Soyuz launched 2 cosmonauts and 1 astronaut to the International Space Station, and for the last time the payload canister for the space shuttle Discovery made its way to Launch Complex 39A (LC39A) at NASA’s Kennedy Space Center (KSC) in Florida. Crews are now preparing to install the payload into Discovery’s cargo bay on Monday morning, which includes the first humanoid robot to fly into space Robonaut-2 or “R2.”

See below for a video of the Soyuz launch.

Alexander Kaleri, Oleg Skripochka and Scott Kelly are now on their way to join three other crew members aboard the ISS station after a two-day trip on the Soyuz.

For the final flight of Discovery, STS-133, the another payload is the reconfigured Leonardo Multi-Purpose Logistics Module (MPLM) now dubbed the Permanent Multipurpose Module. The mission will also carry the Express Logistics Carrier 4 and much-needed spare parts to the International Space Station (ISS).

The mission is slated to launch no-earlier-than Nov.1 at 4:40 p.m. EDT.

A large white canister is hoisted up and the payload that is sealed inside will be removed. From there the canister is taken away, the Rotating Service Structure (RSS) will swing over the space shuttle and then be loaded into the shuttle’s cargo bay. The entire process takes a little over a week.

The canisters that deliver the payload out to the launch pad have been used since the shuttle program’s inception. However, that does not mean that they are destined to go to the Smithsonian or some other world-famous museum. In fact there is no real clear destination for any of these pieces of hardware. As NASA no longer has a clear path forward it is not known whether-or-not the canisters will be used in some future, as-yet-unnamed program.

“They’re pretty old critters, they’ve been with us since the beginning of the shuttle program,” said Scott Higginbotham NASA’s mission manager in charge of payloads. “They’ve delivered all the payloads either to the Orbiter Processing Facility (OPF) for horizontal installation or out here to the pad for vertical installation.”

Additional Shuttle Mission Almost Guaranteed

For some time now there have been rumors and speculation that there will be an additional flight added to the two currently remaining on the shuttle manifest. With the passage of the Senate 2010 NASA Authorization Act (S. 3729) the mission which would be STS-135 – is now all but a certainty. The U.S. House of Representatives approved the Senate bill on a 304 to118 vote. The final hurdle will be the president signing the act into law. From all accounts however, as this bill largely supports the president’s agenda, this should not be a problem and STS-135 should launch during the summer of next year.

The orbiter that will likely fly this mission will be Atlantis, the workhorse of the shuttle fleet. For all intents-and-purposes STS-132, which flew this past May, was the last scheduled mission for Atlantis. However, mission managers were looking at either Discovery or Atlantis to fly the possible STS-135 mission. With Atlantis back at Kennedy Space Center (KSC) since May, the orbiter has had more processing time and it would be easier to prepare for launch.

The crew for this mission has already been selected. The crew will be comprised of Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim. All of these astronauts are space shuttle veterans. Currently they are training under the STS-335 designation which is a “Launch-On-Need” (LON) mission. In the event of an emergency on STS-134, Atlantis would launch to rescue the crew members. There have been LON missions for each post-Columbia flight.

“Having an additional shuttle flight will keep the national treasure we have in the space station very well situated in consumables and supplies, said Lori Garver, NASA’s Deputy Administrator, during a media briefing on Thursday. “I don’t see it as either a luxury or necessity, it us just making good use of a resource and doing it in a safe manner.”

If all goes well on the STS-134 mission, STS-335 will be converted to STS-135 and its mission will change from rescue – to resupply. If this does take place, the payload for this mission will be the Raffaello Multi-Purpose Logistics Module (MPLM) and a Lightweight Multi-Purpose Carrier (LMC).

Outside of the fact that it will be the last mission of the shuttle program, the mission also bears one other distinction. With a crew of four, this is the smallest contingent of astronauts to launch on a space shuttle since STS-6 back in April of 1983.

The rationale behind such a small crew is two-fold. A smaller crew will allow NASA to maximize the amount of payload that is sent to the International Space Station (ISS). The weight of two or three extra astronauts will now go to additional supplies that can be flown to the ISS. In the event that STS-135 itself runs into trouble while on-orbit, the smaller crew would also allow for a rescue by the Russian-built Soyuz spacecraft.

The ISS will more than likely be on-orbit until 2020 and possibly beyond. As such it was viewed as essential that as much supplies as possible were ferried to and stored on the orbiting outpost. The Rafaello MPLM will be maxed out with 16 resupply racks, the most the cargo container can handle, for this mission. The LMC will carry a new coolant pump. The External Thermal Cooling System (ECTS) Pump Module (PM) which dramatically failed recently and was swapped out by spacewalkers Tracy Caldwell-Dyson and Doug Wheelock last month.

NASA’s Year of Finales Continues with Last ET and SRB Events

As the space shuttle program draws to a close, NASA is working to highlight the historic nature of each of the events. On Tuesday, Sept. 28th, the last External Tank of the shuttle program wheeled out of the Pegasus Barge – early. Storm clouds had been swirling around the Kennedy Space Center (KSC) in the early morning hours, pushing the rollout time up.

Weather also conspired to delay the departure of the final Solid Rocket Booster (SRB) segment from the Assembly Refurbishment Facility (ARF). After a brief ceremony that included Kennedy Space Center Director Robert Cabana and Astronauts Chris Hadfield and Gregory C. Johnson it was announced that the final SRB segment would wait in the ARF for a couple more days until the weather system passed. The moment seemed to highlight some of the emotions that those that have worked on the SRBs are currently feeling.

“It’s bittersweet; you know I’ve worked with the people here for the last twenty-years,” said David Beaman the manager for the Reusable Solid Rocket Booster Project, Shuttle Office. “It’s exciting to know that we’ve almost completed the mission, to know that we’re getting ready for the last couple shuttle flights.”

The External Tank traveled from NASA’s Michoud Facility located in Louisiana to NASA’s Kennedy Space Center across the Gulf of Mexico. The trip takes about 5 days and some 900 miles. The Pegasus reached the turn basin near the massive Vehicle Assembly Building (VAB) the day prior. The day was viewed as one of reflection for those that have worked to see that the tanks arrive safely at KSC.

“It’s a sentimental day, almost nostalgic, who knows what the future brings, but at least for the shuttle program this is the last,” said KSC’s External Tank and Solid Rocket Booster Manager, Alicia Mendoza. “We are excited to have the tank, we all had our adrenaline flowing, but at the same time it is sad because it is the last tank.”

While a final determination as to whether or not there will be a third mission added to the two currently scheduled, all signs indicated that this mission will be added. Currently this mission is designated STS-335 and would be a “Launch On Need” (LON) rescue mission for the final scheduled flight of space shuttle Endeavour, STS-134. If and when this mission is given the go-ahead the crew would consist of Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Rex Walheim and Sandra Magnus. The crew would convert from training as a rescue mission to a resupply mission for the space station.

It was Robert Cabana, Kennedy Space Center’s Director that highlighted the importance of the work that was done on both the SRBs and ETs over the past three decades.

“I just want to say thank you for your hard work and dedication, thank you for thirty years supporting space shuttle operations,” said Cabana, a four-time shuttle astronaut, speaking at Tuesday’s ceremonies. “Thank you for supporting an amazing vehicle that made the assembly of the space station that’s on orbit possible, that put the Hubble Space Telescope up there; that put all the probes out there in space that has done all the things that would not have been possible without the space shuttle.”

Kennedy’s Workforce Reflects on Discovery’s Final Flight

CAPE CANAVERAL, Fla. – They work tirelessly, behind the scenes, some work to ensure that the shuttle fleet is ready for the next mission; others work to ensure that the history is recorded and the shuttle program’s story is told. On Monday night one of their wards was rolled out to the launch pad for the final time.

Discovery began her final trip to the pad at 7:24 p.m. EDT. Along the 3.4 miles were many of the employees that have made the shuttle program possible along with their families. The time these folks have spent watching over Discovery vary from a few years to a couple decades and longer.

Stephanie Stilson, Discovery’s Flow Director has been working on OV-103 since 2000.

Everyone has been very professional, very focused so I try not to think about it being the last one,” Stilson said. “I started with Discovery in 2000, so this is my eleventh processing flow with Discovery; I’m very honored to represent the team.”

Stilson like so many of the employees at Kennedy Space Center have strong feeling regarding Discovery in particular as it was the orbiter that got NASA back on its feet after both the Challenger and Columbia disasters.

“Just the emotion behind Return-To-Flight, it had been such a long processing flow, so much had happened, so much was out there for us to think about, with the accident happening our hearts were very low at that point, so, STS-114 was able to really lift the NASA family up.” Stilson stated as Discovery rolled past her in the distance.

For Kennedy Space Center’s News Chief, Allard Beutel the final mission of Discovery helped to punctuate the eight years he has spent with NASA.

“Discovery was the first shuttle that I did my first commentary-countdown, my first 3-2-1-liftoff was with Discovery,” Beutel said. “There’s a little place right here in my heart for Discovery and all the missions that it has done.”

For one person that attended the rollout and the photo op at launch complex 39A the following day however, this was a bittersweet moment. He had followed Discovery for the 23 years that he had worked at the Kennedy Space Center Visitor Complex (KSCVC).

“Discovery is my vehicle, everyone out here as their personal favorite orbiter,” said Nick Thomas who works with the astronauts at the KSCVC during their daily presentations. “She is the first vehicle I saw with my own eyes back on July. 4, 1988, she was the first vehicle I ever visited out on the launch pad, she was the first vehicle I stuck my head into and she launched on my 40th birthday.”

Thomas had a broad smile on his face throughout the interview as he talked about all the good memories he had working in the space industry. However he, like many, acknowledge that there are mixed emotions at seeing the shuttle program come to a close.

“She has seen her time, she deserves a rest and she’s going to go out with a fine mission I am sure of that.” Thomas said. It’s also sad to see her lining up for one last flight, you look out there and you wish her calm winds and smooth seas.”

CAPE CANAVERAL – The space shuttle Discovery, its nosed pointed toward the sky, its belly attached to the massive, orange External Tank (ET) and twin Solid Rocket Boosters (SRB) slowly but surely emerged from the cavernous Vehicle Assembly Building at 7:24 p.m. EDT on Sept. 20. This marks the final time Discovery is scheduled to make the 3.4 – mile trip to Launch Complex 39A (LC39A) in preparation for her last planned mission – STS-133.

Bathed in spotlights Discovery’s last rollout was a bittersweet moment for workers that have cared for the orbiter. Discovery was rolled out four hours earlier than normal so that workers could take pictures. Rollout is conducted in the evening hours to prevent potential damage from possible lightning strikes. The crawler-transporter moves at a blistering mile-an-hour, but despite this slow speed, the vehicle and its precious cargo create an amazing spectacle.

Discovery is currently scheduled to lift off from LC39A on Nov. 1 at 4:40 p.m. EDT. Afterward Discovery will be maintained in flight ready condition in case the orbiter is needed to fly a possible rescue mission. After the end of the shuttle era, Discovery will go to the Smithsonian Air and Space Museum located in Washington D.C.

There are two crawler-transporters that NASA has used to transport spacecraft from the VAB to LC39A. They were originally used to transport the mighty Saturn family of rockets during the Apollo era. The crawler-transporters were designed by Bucyrus International and built by Marion Power Shovel. The vehicles cost $14 million a piece and are the largest self-powered track vehicles in the world.

STS-133 marks the 35th flight to the orbiting outpost and the 39th flight for Discovery and the 133rd flight in the space shuttle program. The crew members for this mission are Commander Steven Lindsey, Pilot Eric Boe and Mission Specialists Alvin Drew, Michael Barratt, Tim Kopra and Nicole Stott. Discovery will deliver and install the Leonardo Permanent Multipurpose Module (PMM), the Express Logistics Carrier 4 as well as deliver critical spare components to the ISS. Also onboard is the first humanoid robot to fly in space, Robonaut-2. For those that have cared for the orbiter however, this is just another day at the office.

“For me seeing Discovery head to the pad brings to mind all the hard work done by the team that has brought us to this point, ” Discovery’s Flow Director, Stephanie Stilson said. “While every rollout is a major milestone for us, this happens to be the last but we are trying to look at it as just another rollout to the pad.”

NASA Names Crew for Rescue Mission or Potential Added Shuttle Flight

Space Shuttle Atlantis. Credit: NASA

NASA announced the names of the four astronauts who will make up the crew of STS-335, the rescue mission that would fly only if there is a problem with the current final scheduled shuttle flight, Endeavour’s STS-134 mission. Additionally, the four crew members will prepare for the “final final” shuttle flight which may be added to the launch manifest, depending on what Congress decides on adding one more mission since Atlantis will be ready to fly.

“These astronauts will begin training immediately as a rescue crew as well as in the baseline requirements that would be needed to fly an additional shuttle flight,” said Bill Gerstenmaier, associate administrator for NASA’s Space Operations. “The normal training template for a shuttle crew is about one year prior to launch, so we need to begin training now in order to maintain the flexibility of flying a rescue mission if needed, or alter course and fly an additional shuttle mission if that decision is made.”

Having a “Launch On Need” crew ready for a rescue flight is based on recommendations made after the loss of space shuttle Columbia in February 2003. NASA has trained a launch on need crew to be ready to fly in the event of irreparable damage to a shuttle while in orbit. Typically, the next crew to fly serves as the rescue crew for the current mission.

The four astronauts are:

Chris Ferguson, a retired U.S. Navy captain and veteran of two previous shuttle missions, would command the flight. Astronaut and U.S. Marine Col. Doug Hurley would serve as pilot, and astronauts Sandy Magnus and retired U.S. Air Force Col. Rex Walheim would be the mission specialists.

If required, the STS-335 rescue mission would launch on shuttle Atlantis in June 2011 to bring home the STS-134 crew from the International Space Station. STS-134 currently is scheduled to lift off on Feb. 26, 2011, from NASA’s Kennedy Space Center in Florida. If converted to an additional shuttle flight, STS-335 would be redesignated STS-135 and targeted to launch in June 2011.

The final rollover for Discovery – SpacePod 2010.09.13

While rollover actually happened on September 9th, I thought it may be fitting to post our rollover/tribute video to Discovery. Unlike the first last mission for Atlantis (as opposed to the last, last mission), there is no hope for an additional flight of Discovery. This is really, really the last time Discovery will roll from the orbital processing facility to the VAB. You’re watching the beginning of the end here.

Space Shuttle Discovery’s Last Rollover to the VAB

Rollover, the name itself is not all that awe-inspiring, the sight however; will take one’s breath away. The Discovery space shuttle emerged from its technological cocoon located in Orbiter Processing Facility-3 (OPF-3) at 7 a.m. EDT on Sept. 9, 2010 and was moved into the expansive Vehicle Assembly Building (VAB) a few hours later. The short, but slow trek allowed workers, many of whom have spent their entire careers servicing the orbiter, to pose with Discovery as she made this voyage. 

Discovery’s trip to the VAB was delayed a day from Wednesday to Thursday, due to a broken water main. Workers found the break in a pipe located near the VAB and repaired it enough to allow second-shift workers to go to work later in the day. 

“The pipe that broke was 50 years old,” said Allard Beutel, a NASA Public Affairs Officer. “The Kennedy team managed to have a work-around in place in under a day.” 

Rollover is an important milestone on the road to flight. In this case, the occasion was all the more historic as it marked Discovery’s final trip to the VAB for this reason. The orbiter is flanked by workers that have worked to see that the shuttle is prepared for flight. They act as guides ensuring that there is no debris along the short drive that the transport vehicle takes from OPF-3 to the VAB. There were several stops along the way to allow photographs to be taken; marking the last time that Discovery is scheduled to move to the VAB in preparation for flight. 

Once inside the VAB Discovery was connected to a crane that hoisted the 171,000 lb. space glider into the air. From there it is mated to a set of Solid Rocket Boosters (SRB) and External Tank (ET) waiting for the orbiter’s arrival. Seeing this massive spacecraft hanging in mid-air alters one’s perceptions about the U.S. space program. It places a powerful spotlight onto the efforts required to put astronauts into orbit.

Approximately two weeks after the shuttle is mated the “full stack” is then ready to head to Launch Complex 39A. This marks the next phase in the path to launch – Rollout. 

Discovery will deliver and install the Leonardo Permanent Multipurpose Module (PMM), the Express Logistics Carrier 4 and provide much-needed spare parts to the International Space Station (ISS). This will be the 35th shuttle mission to the space station. The crew of STS-133 consists of Commander Steven Lindsey, Pilot Eric Boe and Mission Specialists Alvin Drew, Michael Barratt, Tim Kopra and Nicole Stott. 

Although STS-133 will mark the final time that Discovery is slated to take to the skies there had been talk that she could potentially ride to orbit on STS-135. However, if that mission is approved it is likely Atlantis will be the orbiter selected for that flight. Currently, STS-133 onboard Discovery is scheduled to launch from Kennedy Space Center on Nov. 1, 2010 at 4:40 p.m. EDT.
