Link spacecraft on NASA’s Swift reboost rescue mission reports reaction wheel and thruster failures, spinning in uncontrolled at

Bookmark this story

Katalyst Space Technologies says its Link satellite—launched nearly a month ago to reboost NASA’s Swift astrophysics observatory—has developed attitude control problems. Preliminary findings indicate two of Link’s three reaction wheels are inoperable, with reported thruster issues driving an uncontrollable spin that disrupts communications.

Briefing

What Hype is tracking

  • The mission is an in-orbit rescue and reboost attempt for NASA’s Swift Observatory; reported reaction wheel failures and thruster problems directly threaten spacecraft stabilization, communications, and the ability to deliver the intended orbital/attitude outcome.
  • The update includes specific subsystem impact—two of Link’s three reaction wheels not operable—providing actionable insight into near-term recovery feasibility and the risk profile of attitude-control architectures for commercial servicing.
  • Because the spacecraft is already in a disruption state (“uncontrollable spin”), operators’ ability to regain control and maintain link becomes a near-term operational constraint for contingency planning around NASA science assets in orbit.
