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 gasoline spill In a “fast disconnect” on the SLS principal stage, an interface connects the rocket to the gasoline 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 have been in a position to obtain all of the targets we got down to obtain as we speak,” mentioned Charlie Blackwell-Thompson, Artemis launch director with Earth Exploration Systems at KSC, in short notes after Wednesday’s test.
That doesn’t suggest every little thing went easily. For instance, fast disconnect leakage was once more noticed when charging liquid hydrogen. But the crew managed to unravel the issue; They rapidly heated the isolation, permitting it to “restabilize”, decreasing the leakage fee to a suitable 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 response to NASA officers. Explained in a weblog submit (opens in new tab) After finishing the test.
Agency officers mentioned this second leak was smaller than the others and that the Artemis 1 crew was in a position to include it.
NASA is at present 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 believe we will take the info and see what it tells us,” she mentioned. But, she added, “I used to be very inspired by as we speak’s test and she or he surpassed all our targets.”
A number of different issues must also be completed 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 displays 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 present within the strategy 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 go well with. 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 nicely 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 abilities and data gained within the late Thirties or early Forties to ship astronauts to Mars.
