Polaris Program – Cosmic Log

NASA and SpaceX will look into giving Hubble a big boost

NASA and SpaceX say they’ll conduct a feasibility study into a plan to reboost the 32-year-old Hubble Space Telescope to a more sustainable orbit, potentially at little or no cost to NASA.

The plan could follow the model set by last year’s Inspiration4 mission, an orbital trip that was facilitated by SpaceX and paid for by tech billionaire Jared Isaacman as a philanthropic venture. Isaacman, who is now spearheading a privately funded space program called Polaris in cooperation with SpaceX, says he’ll participate in the feasibility study.

“We could be taking advantage of everything that’s been developed within the commercial space industry to execute on a mission, should the study warrant it, with little or no potential cost to the government,” Isaacman said at a news briefing.

If the six-month feasibility study turns into an actual mission, a spacecraft could be sent up to Hubble to lift the telescope from its current altitude of 330 miles to the 370-mile orbit it was in when it was deployed in 1990. Patrick Crouse, Hubble project manager at NASA’s Goddard Space Flight Center, said that could add another 15 to 20 years to the telescope’s life.

Billionaire kicks off new orbital missions with SpaceX

Five months after billionaire tech entrepreneur Jared Isaacman led a crew for a privately funded philanthropic space mission, he’s doing it again. And maybe again, and again.

The Shift4 CEO announced today that he’ll be working with SpaceX on a series of three Polaris Program missions — starting with a Crew Dragon flight that could launch as early as this year, and climaxing with the first crewed orbital flight of SpaceX’s Starship super-rocket.

During the first mission of the series, known as Polaris Dawn, Isaacman and his crew will aim to conduct the first spacewalk done from the Dragon’s hatch, test the laser communication system for SpaceX’s Starlink broadband telecom network, and potentially set an altitude record for orbital spaceflight.

The main goal for last September’s Inspiration4 flight, paid for by Isaacman, was to raise more than $200 million for St. Jude Children’s Research Hospital in Memphis, Tenn. — a goal that was achieved. St. Jude’s will also be a beneficiary this time around, but the prime directive is to test technologies that SpaceX will rely on for future missions to the moon and Mars.

Isaacman said he and SpaceX are splitting the mission cost, but he declined to provide any further details about who’s paying how much. Two of his crewmates for Polaris Dawn — Sarah Gillis and Anna Menon — are SpaceX engineers who specialize in crew operations and training. The fourth crew member is veteran fighter pilot Scott “Kidd” Poteet, who served as a mission director for Inspiration4.

Lots of the details behind the Polaris Dawn mission remain to be filled in: For example, SpaceX still has to create and test spacesuits that can stand up to the vacuum of space. But Isaacman was confident SpaceX would get the job done. “This is an organization that makes things that we never could have imagined and brings it to reality,” he said.
