Development provide ship docks with house station soon after last-minute misalignment – Spaceflight Now

EDITOR’S Notice: Up to date at 2 p.m. EDT (1800 GMT) soon after docking.

Completing a rapid-track, three-hour pursuit of the Worldwide Room Station, a Russian Progress supply ship overcame a previous-minute misalignment and autonomously joined up with with orbiting study complex Thursday with approximately a few tons of fuel, meals and supplies.

The Soyuz-2.1a rocket took off from pad 31 at the Baikonur Cosmodrome at 10:26:21 a.m. EDT (1426:21 GMT 7:26 p.m. Baikonur time) with the Development MS-15 cargo ship.

The mission’s start was timed much less than a minute just before the room station flew right around the start foundation on the distant Kazakh steppe, letting the Development supply provider to chase down the orbiting research sophisticated in a little more than a few hours.

The kerosene-fueled Soyuz launcher headed northeast from Baikonur and lose its four very first phase boosters two minutes just after liftoff. The Soyuz later introduced an aerodynamic shroud that protected the Development supply ship, jettisoned its main phase, and ignited a 3rd stage motor to produce the cargo freighter into orbit.

A live movie feed from a digicam on-board the Progress spacecraft confirmed the Soyuz 3rd phase shutting down its engine and separating nearly 9 minutes into the mission. The Progress MS-15 freighter then unfurled its electricity-building solar array wings and navigation antennas.

Two important rocket burns applying the Development spacecraft’s thrusters happened at at 11:04 a.m., 11:46 a.m., and 12:32 p.m. EDT (1504, 1546, and 1632 GMT) to commence elevating its orbit to match the altitude of the Worldwide Area Station. These maneuvers established the stage for the supply ship’s tactic to the station and a flyaround maneuver to line up with the Pirs module on the Russian section of the investigation laboratory.

Russian cosmonauts checking the supply ship’s remaining tactic found the Progress spacecraft was drifting out of alignment with the docking target on the Pirs module, incorporating some stress to the remaining times of the docking sequence.

Cosmonaut Anatoly Ivanishin questioned if he need to choose manual regulate of the Development spacecraft by means of a command panel within the place station, which serves as a backup to the cargo craft’s automated Kurs rendezvous radar system.

“Are we going to switch to handbook regulate, Moscow?” cosmonaut Anatoly Ivanishin radioed Russian mission handle in close proximity to Moscow.

“Stand by, we do not have a go yet,” mission control replied.

“OK, we are standing by,” Ivanishin explained.

“Everything is nominal, Anatoly,” mission regulate afterwards claimed. “Don’t do anything at all.”

Moments later, the Development contacted the Pirs docking port at 1:45 p.m. EDT (1747 GMT), and ground groups confirmed a superior connection concerning the cargo freighter and the space station.

The docking transpired 3 hours, 19 minutes following the mission took off from Kazakhstan, delivering some 2.8 tons (2.6 metric tons) of gas, foodstuff, materials and other gear to the space station and its 5-person crew.

Russian ground groups loaded 3,351 lbs . (1,520 kilograms) of dry cargo into the cargo freighter’s pressurized compartment, according to Roscosmos, the Russian place agency. Roscosmos says there’s close to 1,322 kilos (600 kilograms) of propellant aboard the Development MS-15 spacecraft for transfer into the area station’s tanks, along with 926 lbs . (420 kilograms) of water and 101 kilos (46 kilograms) of compressed gas to replenish the place station’s respiration air.

The Development MS-13 source ship, which docked with the space station Dec. 9, departed the Pirs docking port July 8 to distinct the way for the arrival of the new cargo freighter. Following its docking Thursday, the Progress MS-15 spacecraft will stay connected with the house station until December, when it will detach and melt away up in Earth’s ambiance.

Ivanishin and and Russian flight engineer Ivan Vagner are joined on the Worldwide Place Station by Expedition 63 commander Chris Cassidy and NASA astronauts Bob Behnken and Doug Hurley.

Cassidy, Ivanishin and Vagner released in April aboard a Russian Soyuz crew capsule. They are scheduled to return to Earth in Oct.

Behnken and Hurley introduced May 30 from the Kennedy Space Center in Florida on the very first flight of SpaceX’s Crew Dragon spacecraft with astronauts. They reached the station May perhaps 31, and are gearing up for undocking as soon as Aug. 1, adopted by re-entry and splashdown off the Florida coastline Aug. 2.
