Mission details

• On Mar 13, 2013 the Station crew held a change-of-command ceremony as Chris Hadfield became Commander. Hadfield will be the first Canadian commander. Expedition 35 formally began, with Hadfield, Romanenko and Marshburn, when Soyuz TMA-06M undocked at 2343 UTC on Mar 15 carrying Ford, Tarelkin and Novitskiy.
• Soyuz TMA-08M was launched at 2043 UTC on Mar 28, 2013 carrying Pavel Vinogradov, Aleksandr Misurkin and Chris Cassidy. The craft docked with the Poisk module at 0228 UTC Mar 29.
• Progress M-17M undocked from Zvezda at 1202 UTC on Apr 15, 2013 and is carrying out Radar-Progress ionospheric tests.
• Ferry ship Soyuz TMA-07M is at Rassvet; Soyuz TMA-08M is at Poisk. Cargo ship Progress M-18M is at the Pirs module.
• On Apr 19, 2013 astronauts Vinogradov, in spacesuit Orlan MK-6, and Romanenko, in Orlan MK-4, began Russian ISS spacewalk VKD-32. The Pirs hatch was opened at 1403 UTC. The astronauts installed the Obstanovka ('Situation') experiment on the Zvezda module. First, two PVK mechanical adapter/processor boxes were attached to the station, MAD-1 and MAD-2. Then the astronauts went to the back of Zvezda and swapped out a laser retroreflector used in European ATV dockings, returning the old reflector to the Pirs airlock. After their trip to the back end of Zvezda where the rocket engines are, they wiped their suits down with towels in case of rocket fuel contamination, and then jettisoned the towels and the Obstanovka cable reel into space at 1719 UTC. Then they took two probe containers from Pirs and unpacked them to stick the ShKD-1 and ShKD-2 sensor complex booms onto their respective MAD adapters. The probe containers were then jettisoned at 1903 and 1906 UTC. After deploying the booms, the astronauts retrieved the Biorisk MSN-3-C2 exposure package and then moved over to the Poisk module to retrieve one of two panels from the Vinoslivost exposure experiment. Unfortunately at 2016 UTC Vinogradov lost hold of the Vinoslivost panel and it floated away. The astronauts returned to Pirs at 2028 UTC and closed the hatch at 2041 UTC, with repressurization of the airlock underway by 2044 UTC. Duration: 6h 38m.

• Progress M-19M was launched on Apr 24, 2013 and docked successfully with Zvezda's aft port at 1225 UTC on Apr 26, and hard docking was complete at 12:34 UTC. Due to the failure of the deployment of one of the spacecraft's Kurs antennae, a software patch was sent up from Russian controllers to bypass restrictions on the Kurs approach. The manual TORU system was on standby with cosmonauts Roman Romanenko and Pavel Vinogradov on the controls in case of a Kurs failure. In the end the automated rendezvous and docking operation procedures using the Kurs docking system aboard the ISS and the Progress was used, although the docking velocity was slower than normal to give engineers a good look at the antenna through the station's camera system.
  Progress M-19M delivered about 365 kilograms (805 lb) of propellant, 50 kilograms (110 lb) of oxygen and air, 410 kilograms (900 lb) of water and about 1,540 kilograms (3,400 lb) of spare parts, scientific equipment and other supplies to the Space Station.
• On May 9, 2013 a serious ammonia coolant leak was discovered on the P6 truss segment, one of the outboard segments of the Station that carries a pair of solar array wings. The 2B solar array section was be shut down to isolate the leak, reducing the power available to operate the Station.
• On May 11, 2013 astronauts Cassidy and Marshburn, in suits EMU 3010 and EMU 3005, carried out spacewalk US EVA-21 (5h 30m) from the Quest airlock to replace a Pump Flow Control System (PFCS) unit suspected to be responsible for the ammonia leak. The Station has eight solar array wings, labelled 1A, 1B, 2A, 2B, 3A, 3B, 4A and 4B. Associated with each wing is one PFCS unit, which is a 111 kg, 1.0 x 0.5m box placed in the IEA (Integrated Electronics Assembly) section of the truss. In addition, two further PFCS units on the P6 Long Spacer (LS) were used as part of the EEATCS Early External Active Thermal Control System used when P6 was installed on the zenith of Z1 between 2000 Dec 3 and 2007 Oct 28, and a spare PFCS was launched on the ESP-1 external stowage platform in 2001.
  
  
  

  Expedition 35 Flight Engineers Chris Cassidy (pictured) and Tom Marshburn (out of frame) completed a spacewalk at 2:14 p.m. EDT May 11, 2013 to inspect and replace a pump controller box on the International Space Station’s far port truss (P6) leaking ammonia coolant. The two NASA astronauts began the 5-hour, 30-minute spacewalk at 8:44 a.m. Credit: NASA

  Following a session of Robonaut 2 operations controlled by ground personnel, Exp.35 FE Chris Cassidy has a few light moments with the robot in the Destiny Laboratory onboard the Earth-orbiting International Space Station. Robonaut 2 is the first humanoid robot to travel to space and the first U.S.-built robot to visit the space station.

• During the spacewalk, the astronauts removed the 2B PFCS unit from the P6 IEA and swapped it with one of the EATCS units on the P6 Long Spacer. Quest was depressurized at 1241 UTC and repressurization began at 1814 UTC. It appears that the ammonia leak has indeed stopped as a result of the PFCS swap.

• On May 12, 2013 at 1948 UTC Expedition 35 commander Chris Hadfield transferred command of Station to Pavel Vinogradov. Meanwhile, Hadfield relased his cover of a David Bowie ballad performed while floating in a most speculiar way sitting in a tin can far above the world. If `Ground Control to Major Tom' rings a bell for you, you'll want : to listen
