Bookmark this story

Axelspace said high-speed communications systems on four of seven medium-resolution Grus-3 optical imaging satellites launched in July have failed and are unlikely to return to nominal service. The failures represent a substantial reduction in planned constellation capacity for Japan’s Earth-observation operator.

Briefing

What Hype is tracking

  • Four of seven satellites in the recently launched Grus-3 constellation have suffered communications-system failures, leaving most of the mission affected.
  • The likely loss of nominal service reduces Axelspace’s planned Earth-observation capacity and underscores the operational risk concentrated in a newly deployed satellite constellation.
