NASA and SpaceX to study possible private Hubble servicing mission

KIHEI, Hawaii — NASA and SpaceX introduced Sept. 29 they’ll research an idea to ship a Crew Dragon spacecraft to reboost, and probably service, the Hubble House Telescope to increase its life.

In a briefing known as on a number of hours’ discover, NASA and SpaceX officers, together with billionaire non-public astronaut Jared Isaacman, introduced an unfunded House Act Settlement to discover the opportunity of not less than reboosting Hubble’s orbit utilizing a Crew Dragon spacecraft. The settlement got here after SpaceX approached NASA in regards to the idea.

“We wish to know what the chances are,” mentioned Thomas Zurbuchen, NASA affiliate administrator for science, on the briefing. “Business partnerships, we now have discovered, have opened the door to new and thrilling alternatives for NASA science and tech exploration by providing new concepts and revolutionary methods to help them.”

The baseline idea would contain a Crew Dragon spacecraft docking with Hubble, probably utilizing a seize mechanism put in on the final shuttle servicing mission in 2009, and elevating its orbit. That orbit has regularly decayed from atmospheric drag and is presently at about 535 kilometers, mentioned Patrick Crouse, Hubble House Telescope undertaking supervisor at NASA’s Goddard House Flight Middle. Continued decay creates a 50% likelihood that Hubble will reenter by 2037.

He mentioned one objective of such a mission could be to boost Hubble’s orbit again to 600 kilometers, the place it was when it was deployed from the shuttle greater than three a long time in the past. “If we have been to get again to 600 kilometers,” he mentioned, “you’d add simply 15 to maybe 20 years of orbit life to the mission.”

Hubble stays in good working situation, and NASA expects the spacecraft to proceed to function by way of the tip of the last decade and maybe into early subsequent decade. Nonetheless, each NASA and SpaceX mentioned they’d not less than think about the power to do some type of servicing to the telescope throughout such a mission.

“We wouldn’t anticipate being on the degree of complexity of a few of the servicing missions that have been completed with the shuttle and NASA astronaut crews from the previous,” mentioned Crouse, “however we’re excited to have a look at what alternatives can be found with our industrial companions.”

The research will take about six months, mentioned Jessica Jensen, vp of buyer operations and integration at SpaceX. “A part of it’s going to be determining the fee and determining a bit little bit of the schedule, what it’s going to take to make this occur and make it occur safely,” she mentioned.

The first focus of the research would be the technical facets of a reboost or servicing mission, she mentioned. “All the pieces is on the desk,” she added, together with whether or not the mission would require astronauts.

If NASA and SpaceX do go ahead with a mission, it may very well be a part of the Polaris Program, an initiative that SpaceX and Isaacman announced early this year for a collection of crewed flights on Crew Dragon and, later, Starship, to check human spaceflight capabilities. Isaacman, who led the non-public Inspiration4 Crew Dragon mission a yr in the past, will command the primary Polaris mission, Polaris Daybreak, now scheduled for the primary quarter of 2023. That flight would come with the primary spacewalk from a Crew Dragon spacecraft.

Isaacman recommended on the briefing {that a} Hubble reboost or servicing mission may very well be the second Polaris mission. “We’d be benefiting from the whole lot that’s being developed inside the industrial house trade to doubtlessly execute on a mission, ought to the research warrant it, with little or no potential price to the federal government,” he mentioned.

Whereas SpaceX has intensive expertise with flying Dragon missions to the Worldwide House Station, it has but to try any type of satellite tv for pc reboost or servicing. On the similar time, a number of firms are creating, or have already demonstrated, robotic in-space servicing applied sciences. One instance is Northrop Grumman’s Mission Extension Car, two of that are docked to Intelsat communications satellites in geostationary orbit to increase their lives.

“We at NASA will take a look at all or any choices which might be within the curiosity of the taxpayer,” Zurbuchen mentioned when requested how NASA would think about these different satellite tv for pc servicing choices. In an announcement, NASA mentioned that “different firms might suggest related research with completely different rockets or spacecraft as their mannequin.”

One trade supply, talking on background, mentioned NASA ought to take a extra formal strategy for learning any servicing choices than the present settlement with SpaceX. That will begin with a request for info in search of enter from firms on how they might reboost or service Hubble.

NASA officers defended the present research. “When folks are available with concepts for issues that might assist us,” mentioned Kathy Lueders, NASA affiliate administrator for house operations, “it’s not an uncommon factor to go do feasibility research.”

“We’re engaged on loopy concepts on a regular basis,” added Zurbuchen. “That’s what we’re alleged to do. I hope you agree. We’re at all times alleged to push the envelope.”
