Top answer
Contracted by NASA under the Small Business Innovation Research Phase 3 contract, Katalyst Space Technologies' LINK servicing spacecraft will rendezvous and attach to NASA’s Neil Gehrels Swift Observatory to re-boost its orbit. This aims to demonstrate a key capability for the future of space exploration and extending the Swift mission’s science lifetime in gamma ray astronomy.
Last refreshed: Jul 03, 2026, 7:47 PM EDT. T-Minus Zero keeps this as the canonical launch record and reconciles schedule, mission, payload, media, and provider signals when those records are available.
Live targets are highlighted across the sequence.
Premium keeps the launch-by-launch change log visible so you can review slips, window edits, and status changes without waiting for an error-driven upgrade prompt.

Alternate mission URLs consolidate to this canonical launch record so exact mission timing, status, media, and source context stay on one page.
Use these internal paths to move from this exact launch record into the provider, vehicle, launch-site, schedule, and mission-family pages that own broader context.
This launch currently has no dedicated mission-family hub, so provider, vehicle, site, and canonical record links are the primary internal paths.
Key structured fields for this launch record are grouped here so the page answers mission, payload, orbit, provider, source, and timing questions before the deeper tracking and media sections.
This record is preserved as historical launch context. The page emphasizes what was launched, the vehicle and pad involved, published outcome/status fields, linked programs, and source records instead of treating the mission like an upcoming countdown.

The Pegasus is an air-launched rocket developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation Systems). Capable of carrying small payloads of up to 443 kilograms (977 lb) into low Earth orbit, the vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 40,000 ft (12,000 m), and its first stage has a wing and a tail to provide lift and attitude control while in the atmosphere.
Northrup Grumman Space Systems designs, builds and delivers space, defence and aviation-related systems to customers around the world. They aquired Orbital ATK in 2018 along with its launchers and ongoing missions.

This launch is waiting for a current solar-geometry calculation. The previous result is not shown because launch timing and sunlight geometry may have changed.
This is a planning index, not a percent chance. Higher means the modeled viewing setup is stronger.

This outlook evaluates whether a broad, sunlit ascent plume could stand out. It does not yet predict whether a specific vehicle will produce one, and an unfavorable plume outlook does not mean the rocket itself will be invisible.
