Russian Progress cargo truck rises from the top of the Soyuz-2.1a booster on Wednesday from Kazakhstan to launch an accelerated pursuit of three-and-a-half hours at the International Space Station with food, fuel, water and more delivery.
Russian officials approved final preparations for the launch early Wednesday, including filling a three-stage Soyuz rocket with kerosene and liquid oxygen fuels.
The Soyuz rocket took about nine minutes to deliver a Progress MS-12 truck.
Four amplifiers from the first stage of the Union shut down and ejected at approximately T + plus 1 minute, 58 seconds, and the stage of the Union core continued to shoot at approximately T + plus 5 minutes. The third stage RD-0110 engine ignited. to complete the mission of orbiting the Progress MS-12 spacecraft.
After separating from the third stage of the Union, the Progress delivery ship deployed its energy-generating solar panels, then expected to launch a series of maneuvers to match its orbit with that of the space station more than 250 miles ( 400 kilometers) above the Earth.
The Progress MS-12 spacecraft is set to connect to the Pirs space station docking station at 1535 GMT (11:35 a.m. EDT) on Wednesday after an accelerated bilateral orbit profile.
Progress MS-12 delivery ship transports over 2600 pounds (1200 kilograms) of dry cargo to the space station inside the spacecraft compartment, including scientific equipment, life support system components, food, clothing, medical supplies and personal belongings for research According to the team of the Russian space agency Roscosmos, a six-person laboratory.
The Progress spacecraft also launched about 1764 pounds (800 kilograms) of fuel in refueling tanks to be transferred to the star service module of the space station. from Roscosmos. The Russian Space Agency said the re-supply mission will deliver about 925 pounds (420 kilograms) of water and 110 pounds (50 kilograms) of compressed gas to replenish the space station's breathing air.
The cargo mission is designated "Progress 73P" in the sequence of refueling and crewed flight to the International Space Station.
The Progress MS-11 delivery ship, loaded with garbage, disconnected from the Pirs module early Monday, embarking on a devastating re-entry to terminate its mission. Much of the spacecraft arriving at the space station in April was expected to burn during the re-entry, with all other debris expected to fall into the distant South Pacific.
The arrival of Russian Progress cargo ship on Wednesday will mark the second delivery of a delivery to the space station in less than a week. A SpaceX Dragon delivery ship arrived at the station on Saturday with 1097 pounds (2312 kilograms) of experiments and equipment after a two-day flight from Cape Canaveral launch site.
Russian teams in Baikonur are preparing another launch of Soyuz on August 22. with the Soyuz MS-14 unmanned aerial vehicle. The mission will test the compatibility of the MS Soyuz spacecraft with the Soyuz-2.1a launcher, which Russia plans to use for crew missions next year.
Soyuz-2.1a has a new digital guidance system and other enhancements, allowing it to carry several hundred kilograms more load in orbit. The Soyuz-FG missile variant, which is currently being used to bring crews into orbit, will be retired after its launch in September.
The Soyuz MS-14 spacecraft will launch without the life support systems required for flight crew, allowing crews to pack additional cargo into the capsule. The spacecraft will dock with the space station on August 24 for a 13-day stay, during which time the astronauts will unpack their shipments and load items to return to Earth.
A Soyuz capsule parachute to a landing in Kazakhstan in early September with up to 1,100 pounds (500 kilograms) of equipment, significantly more cargo than a vehicle from the Union crew usually returns to Earth.
Meanwhile, the Northrop Grumman Cygnus cargo ship arriving at the space station in April is scheduled to depart on August 6 to begin the final phase of its mission, including the deployment of several CubeSats before combustion during re-entry.
The Progress MS-12 spacecraft, due to arrive at the station on Wednesday, is expected to remain attached to the orbital research post by December.
