Astronaut Chris Cassidy (NASA) and Luca Parmitano (ESA) performed an Extra Vehicular Activity (EVA) which began at 1909 GMT on 10 July. During the spacewalk ,which lasted six hours seven minutes, the two astronauts made various equipment retrievals and change-outs including replacing a failed component on an antenna, installing radiator grapple bars onto the outboard P-1 and S-1 trusses, retrieving two materials science experiments, The astronauts also routed power cables in preparation for the arrival of a new NAUKA Russian module.

Ten days after its Ariane 5 launch, the Automated Transfer Vehicle ATV 04 (Albert Einstein) docked with the aft port of the International Space Station’s Zvezda module at 1407 GMT on 15 June. The craft was carrying The craff was carrying 2580kg of propellant to boost itself and ISS to a higher orbit and a futher 860kg of fuel to be transferred. There will also be 570kg of water and 100kg of oxygen and 2,400kg of dry cargo carried.
NASA has decided to fork out more cash to buy extra Soyuz seats to take its crews to the International Space Station. The deal signed with Roscosmos is valued at $424 million is for six “seats” and training and adds to an earlier deal to carry NASA astronauts until 2016. The new deal extension equates to a per seat price of $70.7 million – an increase of $10 million over the previous NASA Soyuz seat buy. NASA found itself forced into this position as its commercial crew capability will now not be ready until 2017 at the earliest and NASA needed to book these seats to cover itself until mid-2017.
Successful Soyuz launch of Progress M-019M is marred by sticky KURS antenna which may prevent docking (Updated)
A Soyuz U launch vehicle successfully launched Progress M-019M (ISS-51P) on its mission to the International Space Station from the Baikonur Cosmodrome located near Tyuratam in Kazakhstan. Aboard were cargo and supplies for the astronauts aboard the International Space Stataion. Due to orbital alignments, the passage to the space station will take the slower route lasting two days rather than the shorter six hour trip. Soon after launch an issue was reported involving the failure to deploy of one of the antennas needed for the KURS automatic docking system. Engineers are attempting to recover the antenna.
On 19 February, flight controllers were in the process of updating the International Space Station’s command and control software when a communications fault related to this transition occured. During the transition from primary computer to the backup computer as part of the software load procedure, there was a loss of all communications with mission control at 1435 GMT. The back up computer was not letting the station communicate with Nasa’s Tracking and Data Relay Satellites, Normal ommunications and telemetry were restored at 1934 GMT using another computer. In the intervening period a secondary radio voice communications were able to made as the station passsed over Russian ground stations.
A video is now available of the unmanned cargo spacecraft Progress M-016M successfully undocking and leaving the International Space Station’s Pirs module. The undocking took place at 1315 GMT on 9 February. Later that day the spacecraft was re-entered over the South Pacific at 1619 GMT with remaining debris impacting at 1715 GMT.
The was a boost for proponents of using “in flight refueling” for spacecraft in space. On the International Space Station, the Dextre robot has just completed experiments under the Robotic Refuelling Mission to test the concept of such satellite servicing. During the six-day experiment, the robot opened a fuel valve on a mock satellite and transfered liquid ethanol into a fuel tank.
Just to give an idea of lead times in spaceflight: Arianespace has begun loading cargo into the European Space Agency’s fourth Automated Transfer Vehicle robotic supply ship, named Albert Einstein – which launches via Ariane 5 rocket for the International Space Station in April. ESA’s launch operator actually began loading ATV4 in late 2012, working […]
Space Year Review 2012: Launch vehicles – Falcon 9, Delta IV and Soyuz show robustness in mishaps but not so for Safir or Proton
According to the Flightglobal SpaceTrak database, at 78 orbital launch attempts in 2012, there were six less launches than in the previous year. With 139 spacecraft on these flights (Shenzhou 9′s orbital module is counted as an autonomous spacecraft) there were two more launched in the year compared to 2011.This increase is mainly as a result of an increase in the number of small satellites of under 100kg (38 in 2012 compared to 23 in 2011) which were often launched as multiple payloads.
US Astronaut Suni Williams and Japanese astronaut Aki Hoshide made a spacewalk EVA (Extra Vehiclular Activity) to set up an alternative pathwway for ammonia coolant apparently leaking on a radiator on the P6 segrment of the International Space Station truss. The astronauts re-routed this to an alternative radiator they had set up. The spacewalk which lasted over six and a half hours began at 1228 GMT (hatch open) and ended at1907 GMT on 1 November, ,
