ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
The Progress MS-02 cargo spacecraft departed the International Space Station on Friday en-route to a fiery re-entry, marking the start of a string of vehicle moves to and from the orbital outpost coming up in the second half of this month.
Progress MS-02 was commanded to undock from the aft port of the Zvezda Service Module at 9:37 UTC and performed departure maneuvers to drift to a safe distance from ISS for the deorbit maneuver, conducted at 12:50 UTC to set up for destructive re-entry over the Pacific Ocean.
Friday’s re-entry of Progress MS-02 closes out a mission of 197 days that started on March 31st with a nighttime liftoff from the Baikonur Cosmodrome atop a Soyuz 2-1A rocket. Arriving in orbit after a flawless ascent, Progress went through a 34-orbit rendezvous with the Space Station to facilitate testing of the new systems upgrades before linking up with the Station for a fully automated docking to the Zvezda Service Module.

Russia’s next Progress cargo freighter rolled out to its launch pad in Kazakhstan on Tuesday in a final move before blasting off Thursday at the tip of a Soyuz rocket to resupply and refuel the International Space Station.
The Progress MS-04 spacecraft and its Soyuz-U booster emerged from an assembly building at the Baikonur Cosmodrome before sunrise Tuesday, and arrived at Launch Pad No. 1 at the historic spaceport after a railroad journey. The rocket was rotated vertical at the launch pad, and work platforms folded in place around the Soyuz for final preflight preparations.
Liftoff Thursday is scheduled for 1451:52 GMT (9:51:52 a.m. EST) to kick off a two-day pursuit of the space station. Launch is set for 8:51 p.m. local time at Baikonur.
The Progress MS-04 spaceship is packed with about 2.5 tons of dry cargo, including food, spare parts, clothing and experiments, rocket fuel, water and compressed gases to replenish the space station’s cabin atmosphere.
The cargo capsule will complete an automated radar-guided rendezvous with the space station Saturday, aiming for docking with the aft port of the outpost’s Zvezda service module at 1643 GMT (11:43 a.m. EST), where it will remain until June.
The Progress MS-04 spacecraft is the first of two cargo missions to ISS planned before the end of the year, the second being the Japanese HTV-6 that is set for liftoff atop an H-IIB on December 9th and a robotic capture on the 13th.
Progress MS-04, loaded with 2,400 Kilograms of food, fuel and supplies, is aiming for liftoff at 14:51:52 UTC on Thursday for a nine-minute climb into orbit atop the trusted Soyuz U rocket to mark the start of a 34-orbit rendezvous with the Space Station. Docking to the Station’s aft port on the Zvezda Service Module is expected at 16:43 UTC on Saturday, kicking off a planned 147-day stay through late April 2017.
Progress MS-04 entered its final processing campaign in November at Site 254 of the Cosmodrome to be loaded with cargo, undergo final checkouts and complete hazardous processing which entails loading the Progress with propellants and compressed gases. While being readied for launch, Progress MS-04 was inspected by the Soyuz MS-03 crew during one of their visits to Site 254 to have a look at the cargo situation aboard the spacecraft before it arrives in orbit.
The fully-fueled Progress MS-04 was returned to the spacecraft processing facility on November 22 to complete a last set of checks before being installed on the payload adapter that provides the structural interface between the launch vehicle, spacecraft and launch shroud. Progress was rolled to a horizontal position on November 25 to be encapsulated in its launch shroud after the last protective covers were removed from the craft’s docking system and navigation sensors.
Progress was shipped from Site 254 to the MIK-112 Launcher Integration Facility on Sunday to be ready to meet its Soyuz U rocket. This mission uses the penultimate Soyuz U vehicle that is being phased out in favor of the upgraded Soyuz 2-1A rocket that will take over all Progress launches starting with the MS-06 mission.

Yep, this one is probably doneRoscosmos, the Russian space agency, tweeted that mission control lost telemetry with the vehicle at about T+plus 6 minutes, 23 seconds, more than two minutes before the Progress spacecraft was to have arrived in orbit.
Interesting indeed...Thursday’s launch failure marks the fourth time in 25 months that a supply ship heading for the space station has fallen short of the complex.
A commercial Orbital ATK Cygnus cargo freighter crashed moments after liftoff in October 2014 when its Antares booster suffered an engine failure, then a Russian Progress spacecraft spun out of control after a botched separation from its Soyuz rocket in April 2015. SpaceX’s Falcon 9 rocket disintegrated in mid-air on a June 2015 launch with a Dragon logistics capsule.
That record signifies a turnaround in fortune for the international research outpost. Only one mission to the space station failed in nearly 16 years of assembly and resupply missions from November 1998 through October 2014.
