Packed with nearly 3 tons of rocket fuel, water, oxygen and crew provisions, the Russian Progress MS-12 supply ship and its Soyuz booster arrived at a launch pad Sunday at the Baikonur Cosmodrome in Kazakhstan, moving a step closer to liftoff Wednesday on a fast-track three-hour flight to the International Space Station.

The automated supply carrier is set for liftoff on top of a Soyuz-2.1a booster at 1210:46 GMT (8:10:46 a.m. EDT; 5:10:46 p.m. Baikonur time) Wednesday.

Riding a rail car, the Soyuz-2.1a rocket rolled out from an assembly building at Baikonur early Monday and journeyed to Launch Pad No. 31, where ground crews raised the launcher vertical using a hydraulic lift amid rain showers and gusty winds.

Twin gantry towers moved into position around the Soyuz rocket to give workers access to the vehicle for final preflight checkouts and inspections.

The Progress MS-12 supply ship will carry more than 2,600 pounds (1.2 metric tons) of dry cargo to the space station inside the spacecraft’s pressurized compartment, including scientific equipment, components for the life support system, food, clothing, medical supplies and personal items for the research lab’s six-person crew, according to Roscosmos, the Russian space agency.

The Progress spacecraft will also launch with more than 2,200 pounds (1 metric ton) of propellant in refueling tanks to transfer inside the space station’s Zvezda service module, according to information released by Roscosmos. The Russian space agency said the resupply mission will deliver some 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 resupply and crew delivery flights to the International Space Station.

Assuming an on-time launch, the Progress MS-12 spacecraft is set to link up with the space station’s Pirs docking compartment at 1535 GMT (11:35 a.m. EDT) Wednesday following an accelerated two-orbit rendezvous profile.

The Progress MS-11 supply ship, loaded with trash, undocked from the Pirs module early Monday, heading for a destructive re-entry to end its mission. Most of the spacecraft, which arrived at the space station in April, was projected to burn up during re-entry, with any remaining debris expected to fall into the remote South Pacific Ocean.

The arrival of a Russian Progress cargo freighter Wednesday will mark the second supply delivery to the space station in less than a week. A SpaceX Dragon supply ship arrived at the station Saturday with 5,097 pounds (2,312 kilograms) of experiments and equipment after a two-day flight from a launch pad at Cape Canaveral.

Russian teams at Baikonur are preparing another Soyuz launch Aug. 22 with the unpiloted Soyuz MS-14 spacecraft. The mission will test the compatibility of the Soyuz MS-series spacecraft with the Soyuz-2.1a launcher, which Russia plans to begin using for crew missions next year.

The Soyuz-2.1a features a new digital guidance system and other upgrades, allowing it to carry several hundred pounds more cargo into orbit. The Soyuz-FG rocket variant previously used to ferry crews into orbit will be retired after a launch in September.

The Soyuz MS-14 spacecraft will launch without the life support systems needed for a crew flight, allowing teams to pack additional cargo into the capsule. The spacecraft will dock with the space station Aug. 24 for a 13-day stay, during which time cosmonauts will unpack the supplies and load items for return to Earth.

The 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 Soyuz crew vehicle typically returns to Earth.

Russia’s Soyuz-2.1a rocket with Progress MS-12 space freighter blasts off from Baikonur

The carrier rocket blasted off from the 31st launch pad at the Baikonur spaceport at 3:10 p.m.

A Soyuz-2.1a carrier rocket with the Progress MS-12 resupply ship blasted off from the Baikonur Cosmodrome to the International Space Station (ISS), Russia’s Flight Control Center reported on Wednesday.

"The carrier rocket was launched in a normal regime," the Flight Control Center said.

The carrier rocket blasted off from the 31st launch pad at the Baikonur spaceport at 3:10 p.m. Moscow time, the Center specified.

The rocket will fire its engines for about nine minutes, after which the space freighter will detach from the carrier’s third stage at 3:19 p.m. Moscow time.

 

The Progress resupply ship will approach the International Space Station using a two-loop scheme lasting 3 hours and 25 minutes. The space freighter will dock to the Pirs docking module at 6:35 p.m. in the automated mode under the control of specialists of the Flight Control Center and the space station’s Russian crew.

The resupply ship is due to deliver 1.2 tonnes of dry cargoes, over a tonne of fuel, 420 kg of water, and also 50 kg of compressed gas in containers. The spacecraft’s cargo compartment holds scientific equipment, components for the life support system, and also containers with foodstuffs, clothing, medications and personal hygiene items.

Currently, Russian cosmonauts Alexei Ovchinin and Alexander Skvortsov, NASA astronauts Nick Hague, Christina Kock and Andrew Morgan and Italian astronaut Luca Parmitano are staying on the space station.

Progress cargo freighter lifts off, reaches space station hours later

A Russian Progress cargo freighter lifted off Wednesday from Kazakhstan on top of a Soyuz-2.1a booster and completed a record-breaking 3-hour, 19-minute pursuit of the International Space Station with an automated docking to deliver 2.7 tons of food, fuel, water and other supplies.

The Soyuz-2.1a rocket lifted off from Launch Pad No. 31 at the Baikonur Cosmodrome at 1210:46 GMT (8:10:46 a.m. EDT; 5:10:46 p.m. Baikonur time) Wednesday, roughly the moment the Earth’s rotation brings the launch site under the space station’s orbital plane.

Russian officials approved final launch preparations early Wednesday, including filling of the three-stage Soyuz rocket with kerosene and liquid oxygen propellants.

The Soyuz rocket took around nine minutes to deliver the Progress MS-12 cargo freighter into orbit.

Four first stage boosters on the Soyuz shut down and jettisoned at approximately T+plus 1 minute, 58 seconds, and the Soyuz core stage continued firing until approximately T+plus 5 minutes. A third stage RD-0110 engine ignited to finish the task of placing the Progress MS-12 spacecraft into orbit.

After separating from the Soyuz third stage, the Progress supply ship unfurled its power-generating solar panels, then began a series of maneuvers to match its orbit with that of the space station more than 250 miles (400 kilometers) above Earth.

The Progress MS-12 spacecraft linked up with the space station’s Pirs docking compartment at 1529 GMT (11:29 a.m. EDT) Wednesday following an accelerated two-orbit rendezvous profile.

The 3-hour, 19-minute flight from liftoff to docking set a new record for the fastest trip to the International Space Station, beating the flight time of the previous Progress resupply mission in April by two minutes.

The Progress MS-12 supply ship carried more than 2,600 pounds (1,200 kilograms) of dry cargo to the space station inside the spacecraft’s pressurized compartment, including scientific equipment, components for the life support system, food, clothing, medical supplies and personal items for the research lab’s six-person crew, according to Roscosmos, the Russian space agency.

The Progress spacecraft also launched with around 1,764 pounds (800 kilograms) of propellant in refueling tanks to transfer inside the space station’s Zvezda service module, according to information released by Roscosmos. The Russian space agency said the resupply mission delivered some 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 resupply and crew delivery flights to the International Space Station.

The Progress MS-11 supply ship, loaded with trash, undocked from the Pirs module early Monday, heading for a destructive re-entry to end its mission.

Meanwhile, a Northrop Grumman Cygnus cargo craft that arrived at the space station in April is set to depart Aug. 6 to begin the final phase of its mission, including the deployment of several CubeSats before burning up during atmospheric re-entry.

The Progress MS-12 spacecraft that arrived at the station Wednesday is expected to remain docked to the orbiting research outpost until December.
