Using a $250K development contract from the Space Force, the small startup Rhea Space Activity hopes to develop a mission for resurrecting Spitzer Space Telescope, now several hundred million miles from Earth and out of operation for three years.

The “Spitzer Resurrector” mission would be a small spacecraft that could fit into a 1-meter-by-1-meter box and be ready to launch as soon as 2026, Usman said. It would then take about three years to cruise to the telescope, during which time the spacecraft will make observations of solar flaring. “We plan to be busy right from the start of the mission,” said Howard Smith, an astronomer at the Center for Astrophysics, which is operated by Harvard University and the Smithsonian, who is involved in the proposed rescue flight.

Once the resurrector spacecraft reaches the telescope, it would fly around at a distance of 50 to 100 km to characterize Spitzer’s health. Then it would attempt to establish communications with the telescope and begin to relay information back and forth between the ground and telescope. This would allow scientists to restart observations.

Essentially, the servicing satellite would act as a relay communications satellite, allowing Spitzer to resume doing the limited infrared observations it had been doing in the last eleven years of its life, after its coolant ran out.

The actual mission of course has not yet been funded, nor is Rhea much more than a startup, with only ten employees. The concept however illustrates the growing practicality of flying such missions. The number of servicing missions to defunct satellites is growing in leaps and bounds, and Rhea, as well as its other partners at the Smithsonian and the Applied Physics Laboratory, are simply using that knowledge for their own benefit.
