Rocket Attached to Aircraft for Katalyst-NASA Swift Boost

Engineers attached a Northrop Grumman Pegasus XL rocket to the company’s Stargazer aircraft at NASA’s Wallops Flight Facility in Virginia on Friday, June 12.

The rocket will carry LINK, a robotic servicing spacecraft from Katalyst Space, into orbit ahead of an attempt to boost NASA’s sinking Neil Gehrels Swift Observatory.

All spacecraft in low Earth orbit experience drag caused by our planet’s atmosphere, which gradually reduces their altitudes unless they have propulsion systems to counteract the effect.

A recent bout of solar activity magnified this effect on Swift, and its orbit has lowered faster than anticipated.

Katalyst selected Northrop Grumman’s Pegasus XL rocket as the best launch option for reaching the observatory in time for LINK to perform the boost procedure, based on the mission’s orbital and programmatic needs. Northrop Grumman will deploy the rocket using Stargazer, the company’s modified L-1011 airplane.

LINK will launch from Kwajalein Atoll, part of the Republic of the Marshall Islands in the South Pacific Ocean, later this month.
