The Hubble Space Telescope was launched into orbit in 1990, and NASA estimates that it will end its lifecycle in the mid-2030s. But one private citizen is taking steps to save the Hubble — seemingly to NASA's chagrin.Â
Jared Isaacman, a wealthy entrepreneur and citizen astronaut, has floated a self-funded maintenance mission to the telescope to expand its lifecycle. A new NPR report reveals that NASA has internally expressed concerns about the safety and possibility of this mission.
NASA's main concern is that Isaacman's proposal involves a spacewalk that would seek to refurbish the telescope by way of SpaceX's Crew Dragon capsule. While a "well-planned" mission could extend the Hubble's usage, a spacewalk of this type is "unnecessary and risky," said Keith Kalinowski, a retired Hubble operations expert.
SpaceX, a private company founded by Elon Musk, has a "willingness to accept risk" that is "considerably different than NASA's," said Dana Weigel, NASA's program manager for the International Space Station.Â
NASA has used spacewalks to refurbish the Hubble before, but SpaceX "has yet to prove that astronauts can safely venture outside of the company's Crew Dragon capsule," said Futurism. SpaceX's capsule does not have an airlock, so "for an astronaut to step outside, the entire interior will have to be depressurized and exposed to the vacuum of space when the hatch opens," said NPR. Also, prior NASA missions could linger around the Hubble for a week, "giving astronauts time to tinker with the hardware, but Dragon doesn't have that capability," said Extreme Tech. |
