Officials prepared Roman to receive a potential uncrewed servicing mission. NASA attached a grapple fixture on the bottom of Roman similar to those used by the robotic arms on the International Space Station and the Space Shuttle. Roman also has navigation aids\u2014a retroreflector and external reference points\u2014to help guide a servicing mission on final approach.<\/p>\n
\u201cWhile Roman is nowhere near as serviceable as the Hubble Space Telescope was, we do have everything that\u2019s necessary to enable the rendezvous and capture and docking with a hypothetical servicer; that\u2019s the point of the grapple fixture,\u201d said Jackie Townsend, Roman\u2019s project manager at NASA Goddard. \u201cThen, in 2020, when we were baselined, we were told that we would focus on refueling. So the blanketing around the fueling port has been designed especially so that it\u2019s easier for a robot to get in there if we needed to refuel.\u201d<\/p>\n
The blanketing around the fueling port also has a magnetic closure to simplify opening and re-closing by a robotic servicer, Townsend told Ars.<\/p>\n
There are no servicing spacecraft currently available that could travel out to Roman\u2019s position a million miles from Earth. Several US companies are developing refueling satellites for use in low-Earth orbit and geosynchronous orbit, primarily for the US Space Force. Two Chinese spacecraft docked last year to conduct the first satellite-to-satellite refueling in geosynchronous orbit.<\/p>\n
Everything else onboard Roman has been working well for more than two weeks since launch, according to Kshatriya, NASA\u2019s highest-ranking civil servant. The telescope opened its aperture cover on September 1, allowing starlight to fall on its primary mirror for the first time.<\/p>\n
\u201cAll the preliminary checks are good,\u201d Kshatriya said. \u201cIn fact, we got some data on the Wide Field Instrument just a couple days ago. All the mirrors, all the CCDs are chilling down\u00a0in the right way. We do\u00a0false current tests to make sure that we\u2019re\u00a0getting the right connectivity, etc. All that\u2019s green across the board\u00a0on all 18 (detectors), which is awesome.\u201d<\/p>\n
Roman\u2019s other instrument, a coronagraph designed for direct imaging of exoplanets, also performed well during preliminary checkouts.<\/p>\n
\u201cWhen we get first light, it\u2019s going to be a big party,\u201d Kshatriya said.<\/p>\n","protected":false},"excerpt":{"rendered":"Officials prepared Roman to receive a potential uncrewed servicing mission.
