NASA’s Artemis 1 moon rocket underwent a main refueling test on Wednesday (September 21), doubtlessly placing it on observe for a deliberate September 27 liftoff.
Artemis 1 It will use a monster to ship an unmanned Orion capsule into lunar orbit Space Launch System (SLS) missile. NASA tried to launch the mission on September 3, nevertheless it was canceled earlier than then Liquid hydrogen gas spill In a “fast disconnect” on the SLS principal stage, an interface connects the rocket to the gas line from the cell launch tower.
Artemis Team 1 Replacing two seals Turn on the fast chapter on September 9 and schedule a fueling test to see if the repair is working. The test came about on Wednesday at Launch Pad 39B at NASA’s Kennedy Space Center (KSC) in Florida and introduced excellent news for the mission.

“We had been capable of obtain all of the targets we got down to obtain right this moment,” mentioned Charlie Blackwell-Thompson, Artemis launch director with Earth Exploration Systems at KSC, briefly notes after Wednesday’s test.
That does not imply every part went easily. For instance, fast disconnect leakage was once more noticed when charging liquid hydrogen. But the group managed to resolve the issue; They shortly heated the isolation, permitting it to “restabilize”, lowering the leakage price to an appropriate degree.
The Artemis 1 crew additionally observed a separate hydrogen leak throughout a “pre-pressurization test,” which was additionally a part of Wednesday’s actions. The test “enabled engineers to calibrate the settings used to optimize the engines through the last countdown and validate the schedule previous to launch day to reduce schedule threat through the countdown to launch day,” in accordance with NASA officers. Explained in a weblog put up (opens in new tab) After finishing the test.
Agency officers mentioned this second leak was smaller than the others and that the Artemis 1 group was capable of comprise it.
NASA is at the moment concentrating on September 27 because the Artemis 1 launch goal, with a backup date of October 2. And regardless of Wednesday’s success, it is too early to make a formal dedication to any of these dates, Blackwell Thompson mentioned.
“I feel we’ll take the information and see what it tells us,” she mentioned. But, she added, “I used to be very inspired by right this moment’s test and she or he surpassed all our targets.”
Just a few different issues must also be finished alongside the way in which for Artemis 1 to begin the search within the subsequent few weeks. The climate has to cooperate, for instance, and it is by no means sure on Florida’s Space Coast. The mission should additionally obtain a Flight Termination System (FTS) certification suite, which is designed to destroy the SLS if it deviates from its path throughout launch.
O US Space Force, which screens the pre-launch vary of the missile, has acquired FTS certification from Artemis 1 for 25 days and is now timed out. The mission requested an exemption; If not awarded, the huge Pad 39B missile should be returned to the car meeting constructing at KSC, the one place the place rehabilitation can happen.
“We are at the moment within the technique of technical discussions with Range,” Tom Whitemire, NASA’s deputy affiliate administrator for joint exploration system improvement, mentioned at a information convention Monday (Sept. 19), referring to the swimsuit. state of affairs. “She was very productive and collaborative.”
Artemis 1 has already acquired an exemption from the STF, which prolonged the certification from 20 days to 25 days.
If all goes effectively with Artemis 1, Artemis 2 will launch astronauts round the moon By 2024, Artemis 3 will put its sneakers on close to the Moon’s south pole in a yr or two. O Artemis Ultimately, this system goals to ascertain a long-term human presence on and across the Moon and to make use of the talents and data gained within the late Nineteen Thirties or early Forties to ship astronauts to Mars.
