Northrop Grumman to Fly Pegasus Intercept Mission to Raise NASA’s Swift Observatory from Decaying Orbit

Northrop Grumman’s Pegasus rocket is scheduled for a time-critical rescue mission in June to prevent NASA’s Neil Gehrels Swift Observatory from making an uncontrolled re-entry. The plan will use Katalyst Space’s LINK spacecraft to intercept Swift in a decaying orbit and boost it to a higher altitude.

Briefing

What Hype is tracking

Shows how launch providers and in-space maneuver partners are operationalizing fast, “on-orbit rescue” capabilities to avert uncontrolled re-entries of high-value science assets.
The effort adds urgency to operational re-entry planning amid findings that solar activity can accelerate atmospheric return rates, increasing the need for timely intervention when orbits decay (Study: Sunspot activity can accelerate LEO reentries).
The mission underscores an emerging standard for meeting strict timing windows—intercept plus boost—to protect mission objectives when satellites/observatories lose altitude faster than planned.
