As preparations continue for the launch of space shuttle Discovery on STS-133, here’s a look back at the history of the oldest orbiter still in service. When this flight is over, 180 people will have flown on Discovery and the orbiter will have traveled over 240 million kilometers (150 million miles).
NASA Sets STS-133 Launch for February 24

Following a Flight Readiness Review today, NASA and Space Shuttle Program managers announced that space shuttle Discovery is ready to launch next week Thursday to finally send the STS-133 mission to the International Space Station. Launch is now scheduled for Feb. 24, at 4:50 p.m. EST. “We had a really thorough review today,” said William Gerstenmaier, NASA’s associate administrator for Space Operations. “Things are looking pretty good.”
The STS-133 crew will bring the Permanent Multipurpose Module (PMM) to the station. The PMM was converted from the multi-purpose logistics module Leonardo and will provide additional storage for the station crew. Later, experiments may be conducted in the module, in fields like fluid physics, materials science, biology and biotechnology.
The first human-like robot will also make the trip to the ISS. Robonaut 2 will become a permanent resident of the station. In addition, Discovery will bring critical spare parts and the Express Logistics Carrier 4, an external platform that holds large equipment.
Managers, engineers and contractors went over the detailed analysis and testing performed on the “stringer” or support beams of Discovery’s external fuel tank during the session and reviewed the repairs and modifications made.
Mike Moses, chairman of the Mission Management Team, described the fix as a “a big metal band-aid” to give the metal beams extra support.
The processes of the repairs and testing involved people throughout the agency and its centers, and the managers at today’s press conference lauded the teams.
“I can’t say enough about the work the teams have done,” Gerstenmaier said. “They’ve done just an outstanding job to get us to where we are now ready to launch.”
The crew also underwent a change recently when astronaut Steve Bowen was assigned to take the place of Tim Kopra who was injured in a bicycle accident.
“Overall the crew was in really good shape and felt really comfortable with this change,” said Moses.
The managers at the FRR approved the February 24 launch date even thought the European resupply ship – the ATV Johannes Kepler — is scheduled to dock at the space station just six hours before Discovery’s launch. Moses said they are confident the ATV will dock, but will be ready to modify the shuttle launch should there be any problems with the ATV.
“If they run into a problem in docking we will discuss the issue in real time,” Moses said at the press conference. “We still might launch that day, we might not, depending on the situation. But the space station program would really like to have the ATV docked during this mission.”
Discovery now sits on Launch Pad 39A at NASA’s Kennedy Space Center in Florida, ready for launch. The countdown will begin Monday at 3 p.m. “We’re in outstanding shape out at the pad,” said Mike Leinbach, shuttle launch director.
NASA Weighs Risks of Unique Photo-Op at Space Station
[/caption]
If all goes well and space shuttle Discovery arrives at the International Space Station the end of February, there will be a distinctive configuration: all the international partners will have a vehicle docked to the completed ISS. With the shuttle program about to retire, this configuration will be unique enough – this is the only time it will happen during the shuttle program — that NASA is considering putting three cosmonauts/astronauts in one of the Soyuz capsules that are docked to the station, have them undock and fly around to take pictures of the entire complex.
The Soyuz could photograph the station, showing the ISS in its final, completed configuration, with the shuttle attached, along with the Russian Progress and Soyuz, the European ATV and the Japanese HTV-1.
NASA managers, engineers and contractors are meeting today, Feb. 18 in a Flight Readiness Review to discuss the photo op. Of course, the Russian space agency would have to go along with the idea, as the task would not be insignificant.
Anytime a spacecraft undocks, there is the possibility of a problem or malfunction, and with people involved, the problems multiply fairly quickly. If for some reason the crew could not re-dock, they would have to deorbit and return to Earth, and the ISS crew would all of a sudden be reduced from six to three. Of course, the shuttle crew would be there, but their stay would be limited.
If the plans gets the OK, the crew doing the photo-op mission would ber Alexander Kaleri, Oleg Skripochka and Expedition 26 commander Scott Kelly.
But you have to admit, the pictures and videos would be spectacular, and as things stand now, this would be the one and only chance to get a picture like this, a sort of family photo of the station and all the vehicles that support it.
The feat is not without precedence, however. The Russians took a similar photo on July 4, 1995, when the shuttle Atlantis was docked to the Mir space station, the first time a shuttle visited the Russian space station. Just before Atlantis undocked to return home, cosmonauts Anatoly Solovyev and Nikolai Budarin undocked in a Soyuz spacecraft and photographed the shuttle’s departure from a distance of about 300 feet.
There was a computer problem during the maneuver, however, and the cosmonauts had to dock manually and everything turned out just fine. And the picture was great, too.
The NASA Twitter feed reporting from today’s FRR meeting said the decision to do the photo op will probably not be made until during the STS-133 mission. NASA management is also deciding today when the Discovery mission will actually launch – right now it is scheduled for February 24, 2011 but they are weighing waiting until February 25, as the ATV Johnnes Kepler will arrive at the ISS on the 24th about 6 hours before the shuttle is scheduled to launch. If there were any problems with the ATV, the shuttle might have to stand down.
Forever Endeavour: USA has Plan to Continue Flying Space Shuttles
[/caption]
She is the youngest orbiter in NASA’s fleet – and she is being looked at to keep her country in space during a period when the U.S. will lack the capability to do so. Both Endeavour and her sister Atlantis are part of a proposal to keep the shuttles flying into 2017. United Space Alliance (USA) submitted the proposal in the latter part of 2010 as part of NASA’s Commercial Crew Development Round 2 ( CCDev2).
NASA asked aerospace firms for concepts and ideas to advance the cause of commercial crew transportation. NASA has offered to provide funding to companies to look into various manned space flight systems. USA submitted the Commercial Space Transportation System (CSTS) – an adapted version of the shuttle’s Space Transportation System title.
USA wanted to make sure that all options for crew transportation to orbit were on the table. That included keeping the orbiters Atlantis and Endeavour in service until 2017. If this plan succeeds, the shuttles could conduct missions as quickly as by the year 2013. They would have to wait for new external tanks to be produced. Two flights annually would cost approximately $1.5 billion.
Although some are calling the proposal a “long shot” the plan has some very tangible merits. It would limit the “gap” between the end of the end of the shuttle era and when commercial space-taxis could begin ferrying astronauts to the International Space Station (ISS). Keeping the shuttles in service would also help to significantly decrease dependence on the Russian Soyuz for access to the orbiting outpost.
“The CSTS could provide a near-term U.S. solution for crew transport until a new system is ready. It could provide a low-risk approach to bridging the gap in human spaceflight since the program has been flying since 1981 and is well understood,” USA spokesperson Tracy Yates told Universe Today. “It could also provide redundancy for human access to the ISS and therefore ensure the continued viability of an important national asset. The concept has the potential to offer a proven vehicle operated by a seasoned workforce at a market-driven price. It preserves down-mass capability, stabilizes a larger portion of the human spaceflight workforce for future NASA programs and keeps more crew transport dollars at home.”
For the Space Coast this proposal would also have the added benefit of staving off the crippling unemployment that has come as part of the one-two punch of the end of the shuttle era and the cancellation of the Constellation Program.
Although the CSTS has a specific date (2017) mentioned – it is capable of remaining in effect until the new commercial systems come online. This proposal would allow NASA to utilize a proven space vehicle and the overall idea of a “commercial shuttle program” is actually nothing new – the idea has been bandied about since the 90s.
However, while the cost is less than the $3 billion the shuttle program cost in 2010, it is basically the same amount that NASA is paying Space Exploration Technologies (SpaceX) for 12 missions to the space station. The NewSpace firm has stated that four manned flights would cost approximately $550 million.
“The main thing that this program has going against it is this, what does the shuttle offer that the HTV, ATV, Soyuz and soon commercial craft can’t offer,” said noted space historian David M. Harland. “In today’s economic climate it makes more sense to pay $50 million or so for a seat on Soyuz.”
NASA Robot and First Whole Sun Picture .. Coming on Super Bowl SUNday
[/caption]
What do NASA, Robots, the Sun and the NFL have in common ?
Well … its Super SUNday … for Super Bowl XLV on Feb. 6, 2011
The unlikely pairing of Football and Science face off head to head on Super Bowl SUNday. Millions of television viewers will see NASA’s Robonaut 2, or R2, share the the limelight with the Steelers and the Packers of the NFL. The twin brother of R2 is destined for the International Space Station (ISS) and will become the first humanoid robot in space. It will work side by side as an astronaut’s assistant aboard the space station.
The fearsome looking R2 is set to make a first ever special guest appearance during the FOX Networks Super Bowl pre-game show with FOX sports analyst Howie Long. The pre-game show will air starting at 2 p.m. EST on Feb. 6.
And there’s more.
The two STEREO spacecraft will reach positions on opposite sides of the Sun on Sunday, Feb. 6 at about 7:30 p.m. in the evening, possibly coinciding with the Super Bowl half time show.
At opposition, the STEREO duo will observe the entire 360 degrees sphere of the Sun’s surface and atmosphere for the first time in the history of humankind.
The nearly identical twin brother of R2 is packed aboard Space Shuttle Discovery and awaiting an out of this world adventure from Launch Pad 39 A at NASA’s Kennedy Space Center (KSC) in Florida. Blast off of the first humanoid robot is currently slated for Feb. 24.
R2 is the most dextrously advanced humanoid robot in the world and the culmination of five decades of wide-ranging robotics research at NASA and General Motors (GM).
This newest generation of Robonauts are an engineering marvel and can accomplish real work with exceptionally dexterous hands and an opposable thumb. R2 will contribute to the assembly, maintenance and scientific output of the ISS
“R2 is the most sophisticated robot in the world,” says Rob Ambrose, Chief of NASA’s Johnson Space Center’s (JSC) Robotics Division.
“We hope R2 should help to motivate kids to study science and space,” Ron Diftler told me in an interview at KSC. Diftler is NASA’s R2 project manager at JSC.
The amazingly dexterity of the jointed arms and hands enables R2 to use exactly the same tools as the astronauts and thereby eliminates the need for constructing specialized tools for the robots –saving valuable time, money and weight.
The robot is loaded with advanced technology including an optimized overlapping dual arm dexterous workspace, series elastic joint technology, extended finger and thumb travel, miniaturized 6-axis load cells, redundant force sensing, ultra-high speed joint controllers, extreme neck travel, and high resolution camera and IR systems.
R2 weighs some 300 pounds and was manufactured from nickel-plated carbon fiber and aluminum. It is equipped with two human like arms and two hands as well as four visible light cameras that provide stereo vision with twice the resolution of high definition TV.
“With R2 we will demonstrate ground breaking and innovative robotics technology which is beyond anything else out there and that will also have real world applications as GM works to build better, smarter and safer cars,” according to Susan Smyth, GM Director of Research and Development.
“Crash avoidance technology with advanced sensors is a prime example of robonaut technology that will be integrated into GM vehicles and manufacturing processes.”

I was fortunate to meet R2 and the Robonaut team at KSC. R2 is incredibly life like and imposing and I’ll never forget the chance to shake hands. Although its motions, sounds, illuminated hands and muscular chest gives the unmistakable impression of standing next to a lively and powerful 300 pound gorilla, it firmly but gently grasped my hand in friendship – unlike a Terminator.
So its going to make for a mighty match up some day between the fearsome looking R2 and the NFL players.
Well apparently, R2 and Howie will be making some predictions on which player will win the MVP award and a GM Chevrolet. Stay tuned.
So come back on SUNday Feb. 6 for NASA’s release of the first ever images of our entire Sun from the STEREO twins.
will see the entire Sun for the first time! Credit: NASA.
NASA Prepares for Extra Space Shuttle Mission
[/caption]
On Thursday, the Space Shuttle Program set a target launch date of June 28, 2011 for the STS-135 mission, the “extra” shuttle flight that was approved in the 2010 NASA Authorization Act. The STS-135 mission – if not required as a “Launch on Need” rescue flight for STS-133 or STS-134 — would have the shuttle Atlantis and a 4-member crew carry a fully-loaded Raffaello multipurpose logistics module to deliver supplies, logistics and spare parts to the International Space Station. Whether the mission actually flies, however, depends on if Congress decides to approve NASA’s proposed budget for 2011. There has been rumors that NASA’s budget could be on the chopping block. But NASA needs to begin preparing in case the flight is approved.
According to Jeff Foust’s Space Politics, the House is expected to vote next week on a resolution to cut discretionary spending back to 2008 levels, a move that, if backed up by later appropriations legislation, would cut NASA spending from the $18.7 billion in FY2010 (and $19 billion in the FY11 proposal) to $17.4 billion. There is sure to be a battle, however, from congressional districts in Texas and Florida who worked hard to get the 2010 Authorization Act passed.
After the Act was signed last fall, in late December the agency’s Space Operations Mission Directorate requested the shuttle and International Space Station programs take the necessary steps to maintain the capability to fly Atlantis on the STS-135 mission.
The Authorization Act of 2010 directs NASA to conduct the mission, and scheduling the flight enables the program to begin preparations for the mission. This would be the 135th and final space shuttle flight.
If approved, the mission also will fly a system to investigate the potential for robotically refueling existing spacecraft and return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems.
The crew consists of commander Chris Ferguson, Douglas Hurley, Sandra Magnus and Rex Walheim. The smaller crew size bypasses the need for a rescue shuttle, as if for some reason Atlantis is unable to return from space, the crew members would be rescued from the station using Russian Soyuz spacecraft.
As far as the next scheduled shuttle flight, STS-133, engineers continue to work on Discovery in the Vehicle Assembly Building Kennedy Space Center to modify the stringers on the external fuel tank. Discovery and its six astronauts are targeted to launch on Feb. 24.
With a bicycle injury to crewmember Tim Kopra, the crew is now joined by Steve Bowen, who flew on the on STS-132 in May 2010, as a replacement. He will be the first astronaut to fly on consecutive missions.
At a press conference on Wednesday, Bill Gerstenmaier, NASA’s Associate Administrator for Space Operations said the astronaut office worked together to figure out who should replace Kopra and figure out the logistics so that the flight would not be delayed even further. “We’ve been working hard on this since Tim had his accident and we think we’ve got a good plan in place,” he said.
“Its was obviously a disappointment for Tim to not be available for this upcoming launch window,” said chief astronaut Peggy Whitson. “He understands that we have to be prepared to fly.”
Whitson said Bowen is a very experienced spacewalker, with five previous spacewalks and very capable in terms of qualifications in the EMU (NASA’s spacesuit). “We felt with a very few additional training runs, he could pick up the timeline, and be able to pull them off with only an additional two runs in the NBL (Neutral Buoyancy Laboratory for each of those two activities.”
The crew also will review robotics procedures today and review spacewalk timelines at NASA’s Johnson Space Center in Houston.
Asked if moral in the astronaut office was taking a hit, with Kopra’s injuries and the possibility of astronaut Mark Kelly stepping aside as commander for the STS-134 mission due to the shooting of his wife, Rep. Gabrielle Giffords, Whitson countered, “Moral here is maybe even better than usual since everyone is pulling together to help the crewmembers during their difficult times.”
STS-133 Astronaut Breaks Hip in Bicycle Accident
[/caption]
The crew of STS-133 has had to cope with the numerous technical issues and delays for their mission, related to both the Ground Umbilical Carrier Plate (GUCP) and to a larger extent the cracks that have cropped up on the shuttle’s external tank. Now they have a new issue to contend with – an injured crewmember.
Astronaut Tim Kopra was involved in a bicycle accident over the weekend and apparently broke his hip. Although NASA has not confirmed the injury, several news agencies have reported the news. More than likely, Kopra will not be able to fly with the rest of his crewmates when Discovery launches on her final mission, currently scheduled to liftoff on Feb. 24th. The accident took place on Jan. 15, leaving little over a month before the scheduled launch.
Kopra, 47, is part of a six member crew that will mark the final time that space shuttle Discovery will head to space. He was scheduled to be the primary spacewalker on the upcoming STS-133 mission, and is a U.S. Army colonel (retired). The spacewalks that NASA astronauts undertake take many months and in some cases years to prepare for.
Preliminary reports say that a backup astronaut has been chosen, but again, NASA has not confirmed the news. NASA does not routinely train backup astronauts for shuttle missions. UPDATE: NASASpaceflight.com is now reporting that astronaut Steven Bowen has been chosen as a replacement, and that the flight of STS-133 will proceed as scheduled.
UPDATE 2: NASA has confirmed Kopra’s injury and has announced that Bowen is the replacement for Kopra. “Tim is doing fine and expects a full recovery, however, he will not be able to support the launch window next month,” said Peggy Whitson, chief of the Astronaut Office at NASA’s Johnson Space Center in Houston. “If for some anticipated reason STS-133 slips significantly, it is possible that Tim could rejoin the crew.”
In a press release by NASA, Whitson added that Bowen is an ideal candidate to replace Kopra. “We have complete confidence he’ll contribute to a fully successful STS-133 mission. He has performed five prior spacewalks. That extensive experience, coupled with some adjustments to the spread of duties among the crew, will allow for all mission objectives to be accomplished as originally planned in the current launch window.”
Bowen will begin training this week with the STS-133 crew, which includes Commander Steve Lindsey, Pilot Eric Boe, and Mission Specialists Alvin Drew, Michael Barratt and Nicole Stott. Bowen also will train to perform the two planned spacewalks of the mission. He will join Alvin Drew to move a failed ammonia pump and perform other external configurations to the station.
STS-133 is scheduled to deliver the Leonardo Permanent Multipurpose Module (PMM). Contained within the PMM is the first humanoid robot to fly into space – Robonaut 2 (R2). Discovery will also transport much-needed spare parts to the orbiting laboratory.
Shuttle Discovery Launch Date Pushed Back Again
[/caption]
NASA managers met on Thursday and ruled out any possibility of space shuttle Discovery’s external tank being ready in time for the launch window that opens on February 3. Now, NASA is shooting for the window that opens on Feb. 27, but is working to see if International Space Station on-orbit operations would allow a launch as early as Feb. 24. More will be known next week and managers hope to set a launch date by January 14.
The space agency reported that progress continues to be made in understanding the most probable cause of cracks discovered on Discovery’s external tank mid-section, known as the intertank. Cracks on support beams called stringers were found after the tank was loaded with cryogenic fuel for a subsequently scrubbed launch attempt on November 5th. Four additional small cracks were found during X-ray examinations of the backside of the tank after Discovery was returned to the Vehicle Assembly Building before Christmas.
Plans are for the repair work to continue through the weekend. The shuttle program also reviewed the plan to modify as many as 32 additional stringers with radius blocks, which will provide added structural support in areas known to carry much of the structural load of the external tank. These radius blocks essentially fit over existing stringer edges through which the securing rivets are installed to provide additional structural support. The radius block modification is a known and practiced structural augmentation technique used extensively on the intertank. This work should begin as soon as the repairs to the three stringers with the four additional small cracks have been completed, likely in the next day or so, and the modification of the additional 32 stringers is expected to be complete next week.
Whether further delays could cause a leapfrog of missions remains to be seen. Launch dates for Discovery and Endeavour will be discussed at the January 13 Space Shuttle Program Requirements Control Board meeting.
Shuttle Discovery’s Crack Woes Deepen
[/caption]
Discovery’s woes deepened this week with NASA engineers finding even more cracks in the orbiter’s external tank. The first crack was noted shortly after a leak was discovered on the Ground Umbilical Carrier Plate (GUCP) Nov. 5. After the first crack was found, technicians found a second and then a third. NASA found the crack on support beams dubbed ‘stringers’ around the intertank region of the tank. They applied what is known in the business as a doubler, a section of metal that is twice as thick as the original – this is done to strengthen the affected area.
On Dec. 17, a tanking test was conducted on the tank. Some 89 instruments were attached to the outside to monitor the tank as it was filled with super-cold liquid oxygen and hydrogen. The external tank can shrink by as much as an inch when these extremely cold liquids enter the tank. As one might imagine, this creates great stress on the tank, as such mission managers had the orbiter rolled back into the Vehicle Assembly Building (VAB) for X-Ray scans and other tests.
These tests are considered to be ‘non-destructive’ but NASA is not able to conduct them out at launch complex 39A. Testing started as soon as the full stack consisting of the orbiter, ET and twin solid rocket boosters were in the VAB.
However, once these scans were completed – NASA had more problems, more cracks were found. Four cracks were found hiding beneath the foam on the side of the ET that faces away from Discovery. Mission managers will now weigh whether-or-not they will go ahead with repairing the damaged section of the ET. They are scheduled to make a final determination on Monday, Jan. 3. If they elect to do so, the repairs will be conducted inside of the VAB and not out at the pad.
STS-133 is a resupply flight to the International Space Station (ISS). When it does launch, it will carry the modified Leonardo Permanent Multipurpose Module (PMM) to the orbiting outpost. Contained within that is the first human-like robot to fly into space – Robonaut-2 (R2). Currently, Discovery is scheduled to launch no-earlier-than Feb. 3 at 1:37 EDT. This mission will mark the 39th time that Discovery has taken to the Florida skies and will be the final scheduled mission in the orbiter’s career.
Twas the Shuttles last Christmas
[/caption]
To mark the occasion of the Shuttle’s last Christmas, space shuttle worker Terry Sibile drafted a touching poem titled; “T’was the Shuttle’s Last Christmas”.
For your enjoyment Terry’s poem is reprinted below; as it appeared at Florida Today. The poem initially was circulated via email at the Kennedy Space Center (KSC) and other NASA sites across the US.
According to this article at Florida Today, Terry is a member of the engineering team dealing with cranes, platforms and doors which abound at the space center.
Only 2 or 3 flights remain before the shuttle is retired – at the peak of its performance – probably around mid-2011. NASA is still evaluating whether the budget will support flying the STS-135 mission to the International Space Station.
So it’s unlikely the shuttles will see another Christmas. Sibile’s poem thus marks another installment in the string of sad and bittersweet “lasts” for the shuttle program – “Our spirits were low … and soon we’d all go.”
The Space Shuttle Launch team at KSC recently created tribute displays to honor the achievements of all 5 Space Shuttle Orbiters and all the NASA and contractor workers involved. See photo above. Sibile’s poetry poignantly puts these displays into words.
‘Twas the Shuttle’s last Christmas by Terry Sibile
‘Twas the Shuttle’s last Christmas
and our spirits were low,
For the program was ending
and soon we’d all go.
We’d processed the Shuttles
with infinite care
And followed each mission
as if we were there.
We made every effort
to achieve all our goals;
We offered our talents,
our hearts and our souls.
Our work was much more
than a meager career;
‘Twas an honor and privilege
beyond all compare.
As this marvel of science
was applauded worldwide,
We looked on each Shuttle
with unfettered pride:
Columbia, Challenger,
Discovery, and then
Atlantis, Endeavour
all ferried brave men
And women to realms
past the confines of Earth,
Uncovering knowledge
of infinite worth.
We rejoiced with each mission’s
success, and we grieved
For the losses too painful
for us to conceive.
And over the years,
something wondrous took place:
We became kindred spirits,
united by Space.
And so, as we part,
I will bear a great loss.
And hope in the future
our paths again cross.
But until then, my friend,
this wish I confide:
Happy Christmas to all
— we had a great ride!
