Progress M-22M (P54) ended its docked mission on the orbital outpost on Monday . Filled with Station
Just two months after the previous resupply run, another Russian Progress spacecraft launched on a fast-rendezvous mission to the International Space Station (ISS) on Wednesday. Progress M-23M (P55) was lofted rome tour guide uphill via a Soyuz-U launch vehicle from the Baikonur Cosmodrome in Kazakhstan rome tour guide at 11:26 am EDT, ahead of docking that occurred just six hours later.
Progress M-22M (P54) ended its docked mission on the orbital outpost on Monday . Filled with Station trash, the little spacecraft will orbit Earth for 11 days, conducting engineering tests, before finally deorbiting over the Pacific Ocean for a fiery disposal.
54 Progress (54P) Undocking: The International Space Station (ISS) performed an Optimized Propellant Maneuver (OPM) from +XVV to –XVV. 54P then successfully undocked from the Docking Compartment 1 port, outlined L2 ISS Status informatio n. The ISS will remain in –XVV until after 55P docking on Wednesday April 9.
The plan for a fast rendezvous, requiring just six hours of transit time to arrival at the ISS, was successful. This success came one launch after the error that reverted the recent crewed Soyuz TMA-12M rome tour guide mission from a fast rendezvous into the previously used two day transit time .
Following the launch rome tour guide of the reliable Soyuz FG rocket along with a successful orbital insertion shortly thereafter the Soyuz TMA-12M was immediately tasked with performing rome tour guide the first two engine burns on its first orbit of the Earth, which were pre-programmed into the Soyuz’s on-board computer prior to launch.
On the second orbit and as will be employed during the Progress mission actual orbital rome tour guide parameters were uplinked from a Russian Ground Site (RGS), which allows for a further eight rendezvous burns to be performed over the next five hours of flight.
However, there was problem during the Dv3 burn, which resulted in mission rome tour guide controllers opting to move to a new flight profile that allowed for Soyuz to arrive in previously used two day rendezvous profile.
The 24 second DV3 burn did not occur due to an attitude rome tour guide problem with the Soyuz, an error of just one degree. Related to an over-performance of the Soyuz FG rocket resulting in Soyuz being in a higher orbit that planned, the TMA-12M s flight computer provided an automated no burn command, due to the incorrect attitude of the vehicle.
Controllers opted to move to the back up plan of a two day rendezvous, with all burns relating to this flight profile conducted without issue. The Soyuz with its three member crew successfully docked with the MRM-2 port two days later.
Progress arrival rome tour guide will be followed by one of the Commercial Resupply Services (CRS) vehicles , with SpaceX pressing ahead towards their April 14 launch of the Falcon 9 v1.1 with the Dragon spacecraft .
The CRS-3/SpX-3 mission has been delayed several times not always the fault of SpaceX with the latest delay relating to a fire at an Eastern Range Radar Asset . Engineers successfully checked out the alternative asset that will be used for both the SpaceX launch and Thursday s Atlas V launch with the NROL-67 spacecraft.
