Title: Engineers Want To Bring Home the World's Oldest Satellite

Link: https://science.slashdot.org/story/25/04/19/1...

Launched in 1958, the "awkward-looking" Vanguard-1 satellite ("the size of a
grapefruit" is the oldest artificial object orbiting Earth. "A team of
researchers and engineers want to retrieve the satellite for closer
inspection and are currently working to find a way to bring Vanguard-1 home,"
writes Gizmodo: Other satellites of its time have reentered through Earth's
atmosphere, burning up in a fiery death, but Vanguard-1 is still in orbit,
silently zooming through the void of space... A team of researchers and
engineers from Virginia-based consulting firm Booz Allen Hamilton have put
together a proposal on how to retrieve the satellite from space, bringing it
back to Earth to study how its equipment has fared over the years, according
to a report by Space.com. The team's proposal is detailed in a study
published in the Aerospace Research Center earlier this year... Considering
how old Vanguard-1 is, the astronauts would need to handle it with care,
according to the team behind the proposal. Before a retrieval attempt, the
team suggests that a spacecraft be sent to rendezvous with the satellite to
inspect its condition up-close. The engineers suggested partnering with a
wealthy space enthusiast willing to fund the outer space venture, or using a
SpaceX vehicle to bring the satellite home. Once it's brought back to Earth,
experts would examine Vanguard-1 to assess its condition - whether it was
struck by space debris, if it's still holding together, and how its time in
orbit has affected the satellite. The satellite could then be placed at the
Smithsonian for display as a sort of time capsule, a reminder of the history
of spaceflight, the team suggests. "Future missions (space debris removal,
materials capture for on-orbit manufacturing, and even deep space
exploration) could build on techniques demonstrated in the retrieval of
Vanguard 1," the paper read. "Retrieving Vanguard 1 would be a challenge, but
an achievable and invaluable step forward for the entire U.S. space
community." "The researchers suggest that the satellite can be placed in a
lower orbit and snagged from space, or reeled into the International Space
Station," according to the article. Space.com shares this assessment from
Bill Raynor, the associate superintendent of the Naval Research Laboratory's
spacecraft engineering division. "For material and radiation effects
scientists and engineers, it would be an unprecedented opportunity for
investigating the effects of long-term space environmental exposure." Thanks
