A private mission to rescue an ailing NASA space telescope may now need a rescue of its own. The LINK spacecraft — designed by private company Katalyst Space to boost the orbit of NASA’s ageing Swift Observatory — is reportedly spinning unexpectedly in the weeks after its launch, so much so that stabilizing the spacecraft will likely delay the telescope rescue.

Katalyst’s LINK spacecraft launched July 3 from a mid-air Northrop Grumman Pegasus XL rocket mounted aboard a modified Lockheed Martin L-1011 airliner. The spacecraft lifted off after less than a year of development, on a mission to catch NASA's nearly 22-year-old Neil Gehrels Swift Observatory before the telescope falls back to Earth.
