Overcoming a down-to the-last second problem, space shuttle Discovery made history today, launching on its final mission to orbit. The most-traveled orbiter is carrying a crew of six astronauts and one human-like Robonaut, along with a new permanent storeroom and supplies for the International Space Station. After waiting nearly four months following the detection of potentially dangerous cracks in Discovery’s external tank and a leak in the Orbiter Maneuvering System pod, a problem with a computer for the Air Force Range Safety Officer nearly thwarted the long-anticipated launch. The crew of STS-133 finally launched on their historic mission, with reinforced ribs, or stringers, in the tank’s “intertank” section and a leak-free OMS, and — two seconds before the launch window would have closed — a working computer in the Range. “That was about as last second as you can get,” said spokesman Allard Beutel from Kennedy Space Center.
Discovery set off on her final journey from a picture-perfect warm February day at Kennedy Space Center in Florida, thrilling enormous crowds of onlookers, a huge international press corp and dedicated Tweet-up attendees.
But the four month delay was not without consequences, as original STS-133 crew member Tim Kopra was injured in a bike accident, and Steve Bowen was chosen to replace him. The crew – which includes Commander Steve Lindsey, pilot Eric Boe, Nicole Stott, Michael Barratt, and spacewalkers Alvin Drew and Bowen — met at the base of the shuttle before climbing on board in a touching moment, giving each other a group hug before setting off on their mission.
In the payload bay is the Permanent Logistics Module – a glorified closet, with the first human-like robot, affectionately named R2, who will become a permanent crewmember on board the ISS.
Discovery has been flying since Aug. 30, 1984. It’s first mission was 41-D, where astronauts deployed three communications satellites. Discovery has completed 30 successful missions, more than any other orbiter in NASA’s Shuttle fleet. The orbiter has undergone 99 different upgrades and 88 special safety tests – just since 2002. Discovery was named after several ships of exploration in human history.
Paving the way for the launch was today’s successful docking at the ISS of the ATV-2 Johannes Kepler, a European re-supply ship for the ISS. The Automated Transfer Vehicle 2 is the size of a double-decker bus, and carries 7 tons of supplies for the station’s six-person crew.

The rotating service structure was retracted on Wednesday night starting around 8 p.m. Feb. 23 over about 25 minutes under a light fog.
In a major milestone, the External Fuel tank has been successfully loaded with 535,000 gallons of liquid hydrogen fuel and liquid oxygen to power Discovery’s three main engines during the 8 1/2-minute climb into orbit. A dangerous leak of gaseous hydrogen is what caused the launch scrub last Nov. 5.
Pumps will continue to trickle propellants into the tank to replace the small amounts that evaporate during the countdown.
It’s an absolutely gorgeous day here at KSC with clear blue skies, calm winds and a crackling excitement that permeates the air for everyone here for the launch.
The weather forecast has been upgraded to 90% GO from 80% yesterday which was cloudy and overcast. A few low lying clouds are the only concern.
Large public crowds have gathered at public viewing areas along Florida’s Space Coast. The hotels are full of folks excited to see the historic final launch of Discovery on its 39th and final mission.
The Johannes Kepler ATV is due to dock at the ISS at about 12 noon. A successful docking is an essential prerequisite to clear Discovery for liftoff.
The countdown clock is ticking down towards the final blastoff of Discovery.
The veteran crew of five men and one woman led by Shuttle Commander Steve Lindsey arrived on Sunday on a wave of T-38 jets.
The primary goal of the STS-133 mission is to deliver the “Leonardo” Permanent Multipurpose Module to the ISS. The R2 Robonaut is packed Inside Leonardo along with science equipment, spare parts, clothing food and assorted gear.
The twin brother of R2 is on hand at KSC to watch his brothers launch. He also sports a fancy new set of wheels patterned after the rocker bogie system of NASA’s Mars rovers Spirit and Opportunity.
On Thursday, the European ATV Johannes Kepler will dock with the International Space Station. Rendezvous and docking in space has been taking place for 45 years, and happened first when Gemini 8 hooked up with the Agena Target Vehicle in 1966. Most of us take for granted how two spacecraft rendezvous while in orbit, but it is a complicated procedure involving orbital mechanics, coordination between the two spacecraft, and strict timelines. Here’s a 90-second whirlwind tour of the history of docking in space – past, present and future from ESA. If you want to read more about the history rendezvous and docking, ESA’s ATV blog has a detailed look. Below is a video that describes how the ATV docks at the ISS.
CAPE CANAVERAL – Arriving in their trademark T-38 Talon jets, the crew that will fly the last mission of the space shuttle Discovery arrived at NASA’s Kennedy Space Center in Florida. The astronauts landed at the Shuttle Landing Facility (SLF) at 3:45 p.m. EDT and took a few moments to speak to members of the media and pose for pictures before heading off to prepare for their 11-day mission.
Discovery is currently slated to begin its mission to the International Space Station (ISS) with liftoff taking place at 4:50 p.m. EDT Thursday, Feb. 24. The STS-133 mission is Discovery’s final scheduled flight. However, STS-132, which took place this past May, was shuttle Atlantis’ final scheduled flight – now that orbiter is scheduled to close out the shuttle program when it completes mission STS-135, which is scheduled to take place late this summer.
The crew will deliver the Leonardo Permanent Multipurpose Module (PMM) to the space station. The PMM was modified from the Multi-Purpose Logistics Module (MPLM) Leonardo – which was essentially a cargo container. Now, Leonardo will be a permanent fixture on the orbiting outpost providing additional storage for the station’s crew.
On the way to orbit, the PMM will carry, among other things, the first human-like robot ever flown in space, Robonaut 2 (R2). R2 will stay onboard the station and will be used to test the viability of similar robots in assisting astronauts on future long-duration missions. One of the things that the station can always use – is more spare parts. STS-133 will deliver various parts and the Express Logistics Carrier 4, a platform that holds large equipment.
The crew consists of Commander Steve Lindsey, Pilot Eric Boe and Mission Specialists Alvin Drew, Steve Bowen, Michael Barratt and Nicole Stott. Bowen is a last minute addition to the crew. He replaces Tim Kopra who broke his hip in a bicycle accident.
Check out the spectacular launch photo (above) of the Johannes Kepler ATV streaking skyward atop an Ariane 5 rocket as captured by astronaut Paolo Nespoli from his unparalleled vantage point looking out the windows aboard the International Space Station (ISS), in orbit some 350 km above Earth.
The launch photo shows the rising exhaust trail from the rocket just minutes after blast off of the Ariane booster on Feb. 16 from the ESA rocket base in Kourou, French Guiana, South America. The rocket was still on a vertical ascent trajectory to orbit. Additional launch photos below from space and Earth.
The photo vividly illustrates the maturity of the European space effort since the launch base, Ariane booster rocket, Kepler payload and astronaut Nespoli all stem from Europe and are crucial to the future life of the ISS.
Kepler is set to dock at the ISS on Feb. 24 and an on time arrival is essential because of an impending orbital traffic jam.
Space Shuttle Discovery is due to link up with the ISS just six hous after Kepler if the orbiter launches according to schedule on Feb. 22.
Everything is nominal with Kepler’s spacecraft systems and orbital performance at this time say European Space Agency (ESA) officials, including the deployment of ATV’s four large solar wings.
The ATV, or Automated Transfer Vehicle, is a European built resupply vessel designed to transport essential cargo and provisions to the ISS. It is Europe’s contribution to stocking up the ISS.
Kepler is carrying carries more than seven metric tons of supplies and cargo for the ISS and will be used to reboost the outpost to a higher orbit during its planned four month mission.
“ATV is a truly European spacecraft. Flying it requires experts from ESA, partner agencies and industry across half a dozen countries,” said ESA’s Bob Chesson, Head of the Human Spaceflight Operations Department.
“Getting it built, into orbit and operating it in flight to docking requires a lot of hard work and dedication from hundreds of people.”
The ATV is named after Johannes Kepler (1571-1630), the German astronomer and mathematician who is best known for discovering the laws of planetary motion. NASA also named its powerful new planet hunting space telescope after Kepler, which recently discovered the first earth sized planets orbiting inside the habitable zone.
After the shuttle is forcibly retired later this year in 2011, the very survival and continued use of the ISS will be completely dependent on a steady train of cargo and payloads lofted by unmanned resupply vessels including the ATV from Europe, HTV from Japan, Progress from Russia and commercial carriers such as SpaceX and Orbital Sciences.

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.
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.
Here’s a chance to practice your French countdown skills: watch today’s successful launch of the European Space Agency’s Automated Transfer Vehicle “Johannes” on a Arianespace Ariane 5 rocket blasted off on Feb. 16, 2011, carrying the “Johannes Kepler” cargo-carrying vehicle to the International Space Station. It will take eight days for the ATV to arrive and dock to the aft end of the International Space Station’s Zvezda Service Module. This is the second of ESA’s resupply vehicles, and is loaded with about seven tons of supplies and propellant for use by the six crew members on the ISS.
After yesterday’s scrub of Johannes Kepler, NASA had said that a launch of the ATV today (Wednesday) might delay the launch of space shuttle Discovery for STS-133. However, today, NASA said that might not be the case. Officials will decide Discovery’s launch date at the Flight Readiness Review on February 18. Currently, STS-133’s launch is scheduled for Feb. 24.
The European Space Agency’s Automated Transfer Vehicle-2 (ATV-2) “Johannes Kepler” launch that was scheduled for Tuesday Feb. 15 was scrubbed due to a technical issue on the launch pad, and the slip could affect which day space shuttle Discovery launches for STS-133. Technicians at Launch Complex 3 in Kourou, French Guiana are looking at the problem, but preliminary details indicate some erroneous data on the status of the tank levels for fuel on the Ariane 5 rocket. They will go over the data carefully and if everything looks good they try again on Wednesday, Feb. 16.
This launch slip could change the launch date for STS-133, which is now scheduled for Feb. 24. If the ATV does launch on Wednesday (or on Thursday or Friday of this week), the launch of STS-133 will move to Feb. 25. But if the ATV launch slips beyond Friday means that the STS-133 launch stays on Feb. 24.
You can watch the launch attempt on Wednesday on NASA TV, and coverage will begin at 4:15 EST (21:15 GMT), with launch time at 4:50 pm EST (21:50 GMT). This is second launch of an ATV, and the 200th Ariane 5 launch.
The Orion crew cabin – know as the Ground Test Article or GTA – was shipped by truck and will arrive in Denver on Feb. 14 according to a Lockheed Martin spokesperson.
The next step at Denver is to install the heat shield and thermal protection backshell. The pathfinding vehicle will then be subjected to performance testing inside the acoustic and environmental testing chamber. The testing exercise ensures the vehicle can meet the challenges of ascent, on-orbit operations and safe landing.
“This is a significant milestone for the Orion project and puts us on the right path toward achieving the President’s objective of Orion’s first crewed mission by 2016,” said Cleon Lacefield, Lockheed Martin vice president and Orion program manager. “Orion’s upcoming performance tests will demonstrate how the spacecraft meets the challenges of deep-space mission environments such as ascent, launch abort, on-orbit operations, high-speed return trajectory, parachute deployment, and water landings in a variety of sea states.”
Engineers for Lockheed Martin successfully finished the initial construction and testing phase for this prototype Orion crew cabin at New Orleans. The final pieces of the Orion GTA were welded together in late May 2010 using a state of the art friction stir welding process. See photos below from my inspection tour of the newly welded Orion GTA.
The spacecraft underwent proof pressure testing this past fall. Several mass and volume simulators including the parachutes were installed by the technical team to ready the capsule for shipment.
In Denver, the vehicle will be bombarded with acoustic energy and vibrations to simulate flight like situations that correlate the structural environment inside and outside the vehicle. The tests will determine if the spacecraft was properly designed to survive the harsh rigors of spaceflight. Lessons learned will be incorporated into the tools and manufacturing processes that will eventually lead to a human rated production vehicle.
The GTA vehicle will then be transported to NASA’s Langley Research facility for drop tests to simulate, validate and certify a variety of water landing scenarios at the new Hydro Impact Basin. The Langley facility will be used to test and certify water landing for all human-rated spacecraft for NASA according to Lockheed.
NASA and Lockheed hope to launch the first unmanned Orion test flight in 2013 if the budget allows. Construction of the service module and other key components is in progress.
Orion has achieved other significant development milestones in the past year.
The emergency abort rocket was successfully tested on May 6, 2010 at the U.S. Army’s White Sands Missile Range near Las Cruces, N.M. The abort rocket is bolted atop the crew cabin and is designed to pull the capsule away from the launcher in a split second in an emergency and save astronauts lives.
“The Phase 1 Safety Review was completed in June 2010 and formally acknowledges that Orion’s design meets all of NASA’s critical safety requirements for a human-rated space flight vehicle for flights to low earth orbit (LEO), lunar and deep space missions,” according to Larry Price, Orion Deputy Program Manager at Lockheed Martin.
In the past year the Orion budget has been cut significantly by NASA due to lack of funding from the federal government and the outlook for future funding is uncertain. The new Congress is aiming to cut NASA’s research and development budget even further.
Lockheed Martin Space Systems Company is the prime contractor for Orion and designed and built the GTA as part of a multiyear contract awarded by NASA worth some $3.9 Billion US Dollars. The goal is to produce a new, US-built manned capsule capable of launching American astronauts into space in the post shuttle era.
As soon as the shuttles are retired – for lack of money – the United States will have no capability to loft American astronauts to the International Space Station (ISS) for at least several years. NASA – and all other ISS partners – will be wholly dependent on the Russian Soyuz capsules for launching astronauts to the ISS until either the Orion or commercially developed space taxis such as the Dragon spacecraft from SpaceX are ready for flight. The first operational unmanned Dragon was test flown in Dec 2010.
The Obama Administration sought to cancel Orion in Feb. 2010 as part of NASA’s Project Constellation Return to the Moon program, but then decided to continue Orion’s development after the cancellation proposal met strong bipartisan opposition in Congress.
Orion was to have been launched atop the Ares 1 rocket which has now been officially cancelled. NASA has started the design of a replacement for the Ares 1 which will most likely be a shuttle derived vehicle. Congress has mandated that the first test flight of the still undefined heavy lift rocket must take place by 2016.
Alternatively, Orion could be launched atop a Delta 4 Heavy booster after the rocket is man-rated.
