wrote in an open letter<\/a> to NASA Administrator Jared Isaacman in January.<\/p>\nIsaacman said that month, however, that he has \u201cfull confidence\u201d in Orion\u2019s heat shield. <\/p>\n
Wiseman, too, has said he is comfortable with the plan.<\/p>\n
\u201cIf we stick to the new re-entry path that NASA has planned, then this heat shield will be safe to fly,\u201d he said during a preflight media event in July.<\/p>\n
The re-entry plan requires the Orion capsule to remain on an extremely precise path, Radigan said. Mission controllers spent the past day and a half keeping the Orion spacecraft on course for that, performing necessary engine burns to maintain its trajectory.<\/p>\n
\u201cLet\u2019s not beat around the bush,\u201d Radigan said. \u201cWe have to hit that angle correctly. Otherwise, we\u2019re not going to have a successful re-entry.\u201d<\/p>\nArtemis II flight controllers monitor the Orion spacecraft from the White Flight Control Room at Johnson Space Center in Houston on Monday.<\/span>Ronaldo Schemidt \/ AFP – Getty Images<\/span><\/figcaption><\/figure>\nDuring atmospheric re-entry, the Orion capsule is expected to reach an estimated maximum velocity of nearly 24,000 mph. The astronauts will be exposed to G forces equivalent to around 3.9 times the normal pull of Earth\u2019s gravity.<\/p>\n
As the capsule plunges through the atmosphere, a communications blackout is anticipated as plasma builds up around the spacecraft and causes interference. The blackout is expected to last around six minutes, flight director Rick Henfling said at a briefing Wednesday.<\/p>\n
\u201cOnce that six-minute blackout is done, Orion is going to be at about 150,000 feet, so still falling pretty quickly,\u201d he said.<\/p>\nArtemis II commander Reid Wiseman peers out of one of the Orion spacecraft’s main cabin windows, looking back at Earth, as the crew travels toward the moon on Saturday. <\/span>NASA<\/span><\/figcaption><\/figure>\nAt an altitude of about 6,000 feet, the capsule will deploy its three main parachutes, which will help slow it down to around 20 mph before it splashes down in the ocean.<\/p>\n
The U.S. Navy will assist with recovery efforts in the Pacific. Once the landing area is deemed safe, NASA\u2019s plan is to extract Koch from the capsule first, then Glover, followed by Hansen and then Wiseman.<\/p>\n
At the briefing Thursday, Kshatriya praised the crew members and said it\u2019s time for flight directors, engineers and recovery teams to bring them home.<\/p>\n
\u201cThe crew has done their part,\u201d he said. \u201cNow we have to do ours.\u201d<\/p>\n<\/div>\n
