Russian Cargo Missions Resume After Technical Setback

A Soyuz-2.1a rocket successfully lifted off on March 22, 2026, carrying the Progress MS-33 cargo spacecraft toward the International Space Station. The launch took place from the Baikonur Cosmodrome in Kazakhstan at 11:59 UTC.

This mission, also referred to by NASA as Progress 94, follows a two-day rendezvous profile, with docking expected on March 24, 2026. The successful liftoff signals a strong return to operational stability for Russia’s cargo missions.

Baikonur Launch Pad Returns to Service

The launch holds added significance as it marks the first use of Site 31/6 since it was damaged during the Soyuz MS-28 mission in late 2025.

Repair work took several months, forcing delays in scheduled launches. The successful ignition and ascent of Soyuz-2.1a confirm that the launch infrastructure has been fully restored. This is a key development for Roscosmos, ensuring uninterrupted access to space for cargo and crew missions.

The Progress MS-33 spacecraft is carrying a total of 2,509 kilograms of cargo, essential for sustaining the six-member crew of Expedition 74 aboard the ISS.

Cargo breakdown includes:

  • 1,200+ kg of dry cargo including food, personal supplies, and scientific equipment
  • 828 kg of propellant for station reboost and maneuvering
  • 420 kg of drinking water
  • 50 kg of oxygen to maintain onboard atmosphere

Additional items include medical kits and research hardware, ensuring continuous scientific operations in microgravity.

The spacecraft is scheduled to dock with the Poisk module of the ISS at approximately 13:34 UTC on March 24 (around 7:04 PM IST).

The approach is being guided by Russia’s automated Kurs docking system. However, officials reported that one of the two Kurs antennas failed to deploy properly after separation from the rocket.

Mission controllers at Korolev are closely monitoring the situation. Backup options, including the manual TORU control system, remain available if needed. Despite the minor issue, the spacecraft remains on a stable trajectory.
