Critical Progress Resupply Mission Set for Friday Launch

Comments

UPDATE: Looks like the launch went well. Progress is in orbit, solar arrays deployed.

Russia’s preparing to launch a critical Progress resupply mission containing more than 3 tons of food, fuel, water, oxygen and other supplies to the International Space Station on Friday. The launch of Progress M-28M is set for 0455 GMT (12:55 a.m. EDT).

Progress flights usually attract little attention. However, this flight is seen a crucial following the loss of SpaceX’s Dragon freighter last summer in a launch accident. It was the third launch failure involving an ISS resupply ship in eight months.

On April 28, a Progress vehicle began tumbling out of control after it reached orbit. The mission was eventually abandoned. Last Oct. 28, an Orbital Sciences Antares rocket exploded shortly after liftoff, destroying a Cygnus cargo ship.

Russians officials have blamed a problem with the third stage of the Soyuz-2.1a rocket for the Progress failure. For this launch, they have switched to a Soyuz-U launch vehicle that is not susceptible to the same problem.

The resupply ship is scheduled to arrive on Sunday at 0713 GMT (3:13 a.m. EDT) with an automatic docking to the space station’s Pirs compartment.

Sunday’s Commercial Cargo Mission Loss

Background

Sunday’s (6/28/15) SpaceX cargo resupply launch to Station failed, breaking up a little over two minutes into the flight. (More here and here.) This was SpaceX’s eighth such flight; their initial test mission then six commercial-contract cargo flights had essentially gone as planned. This was SpaceX’s nineteenth launch of the Falcon 9 booster; the first eighteen F9 launches all reached orbit successfully.

There was a lot of discussion on Sunday about the impact of the loss of SpaceX’s Dragon spacecraft on the International Space Station. NASA officials said the ISS crew was in no danger from a supply standpoint, and they said they would stick to the existing schedule for crew rotation but might change the cargo manifest.

Some notes from the NASA press conference covering the loss of Falcon 9 and the Dragon resupply ship on Sunday morning.

Cause of the Accident & Investigation

The cause is as yet undetermined. SpaceX CEO Elon Musk, who was not at the press conference, Tweeted that there was an overpressure event in the second stage liquid oxygen (LOX) tank prior to the launch vehicle breaking up. “Data suggests counterintuitive cause,” he wrote. Video of the accident appears to show the breakup of the vehicle beginning there.

Hearing the news of today’s loss of SpaceX CRS-7 cargo resupply mission to the International Space Station, ESA Director General Jean-Jacques Dordain stated: “We at the European Space Agency deeply regret this failure that shows that sending launchers into space is a very hard job. However a failure does not undermine all the previous successes. We wish our colleagues on the other side of the ocean all our best in fixing the problem and getting back into flight again soon”.
