  • while the coolant is vital to the operation of the ISS for the electricity-supplying systems, the crew is not in any danger
  • The ammonia cools the 2B power channel, one of eight power channels that control the all the various power-using systems at the ISS
  • All the systems that use power from the 2B channel, the problem area, are being transferred throughout the day to another channel
  • ...2 more annotations...
  • The 2B channel will eventually shut down when the coolant is depleted, and the power is being diverted in order to keep everything up and running on the station
  • While Cassidy and Marshburn prepare in space, Astronauts at NASA’s Johnson Space Center are using the Neutral Buoyancy lab – a 12- meter (40 ft.) deep swimming pool with mockups of the space station that simulates the zero-gravity conditions in space – going through the entire expected EVA

  • The new abbreviated four-orbit rendezvous with the ISS uses a modified launch and docking profile for the Russian ships
  • It has been tried successfully with three Progress resupply vehicles, but this is the first time it has been used on a human flight.
  • In the past, Soyuz manned capsules and Progress supply ships were launched on trajectories that required about two days, or 34 orbits, to reach the ISS.
  • ...2 more annotations...
  • The new fast-track trajectory has the rocket launching shortly after the ISS passes overhead
  • Then, additional firings of the vehicle’s thrusters early in its mission expedites the time required for a Russian vehicle to reach the Station

  • A total of 779 student teams submitted proposals for the 15 science slots and nearly 5,000 students offered 2,299 insignia ideas from which just 22 were chosen.
  • Ironically, none of the almost two dozen student mission patches that were selected to fly depict the vehicle that their experiments are riding on.
  • The designs, which range from crayon-colored creations to computer-assisted drawings, also include representations of the Earth, moon and Mars and the American flag.
  • Aquarius, which utilizes liquid mixing tube assemblies that function similar to commercial glow sticks

  • When the students' experiments were re-manifested, they went from launching on the Russian rocket to the SpaceX Dragon.
  • The Aquarius package will stay in space for just under six weeks before coming back to Earth on Soyuz TMA-03M, the same spacecraft returning three ISS crew members on July 1.
  • The students' patches will also make the round trip, and will be embossed with a certification stating that they flew in space.

  • dual drogue parachutes deploy at 45,000 feet to stabilize and slow the spacecraft
  • Full deployment of the drogues triggers the release of the main parachutes, each 116 feet in diameter, at about 10,000 feet
  • picture perfect splashdown at 11:42 a.m. EDT today, May 31, in the Pacific Ocean, off the west coast of Baja, California, some 560 miles southwest of Los Angeles
  • ...4 more annotations...
  • It will take about two days to deliver the craft to the port of Los Angeles where the most critical cargo items will be removed for quick shipment to NASA
  • The de-orbit burn to drop Dragon out of orbit took place precisely on time at 10:51 a.m. EDT for a change in velocity of 100 m/sec about 246 miles above the Indian Ocean directly to the south of India as the craft was some 200 miles in front of the ISS
  • The Draco thruster firing lasted 9 minutes and 50 seconds and sent Dragon plummeting through the Earth’s atmosphere where it had to survive extreme temperatures exceeding 3000 degrees F (1600 degrees C) before landing.

  • The torch was brought into space two days later
  • during an EVA on Nov. 9, and handed off from one cosmonaut to the other in a symbolic relay in orbit
  • “symbolic” because the torch was not lit during its time aboard the ISS or, obviously, while in space
  • the ISS travels around the Earth 16 times each day, and the torch spent nearly four days in space
  • it will be that particular spacefaring torch that will be used to light the 2014 Olympic cauldron during the Opening Ceremony in Sochi on Feb. 7.
