![]() ![]() NASA will be eager to launch Artemis before Sep. "Had we launched on any one of those scrubs, it wouldn't have been a good day," he said. Nelson added that his own space shuttle launch, held in 1986 while he was a member of Congress, had four scrubs before it eventually took off. "There are millions of components of this rocket and its systems, and needless to say, the complexity is daunting when you bring it all into the focus of a countdown." It's not going to fly until it's ready," NASA administrator Bill Nelson told reporters on Monday following the scrubbed launch. NASA's new moon rocket spotted from space rolling to the launch pad (photos) NASA astronaut Mark Vande Hei back on Earth after record-breaking mission 5 strange, cool things we've recently learned about the moon "Otherwise, relying on such an expensive single-use, heavy-lift rocket system will, in our judgment, inhibit if not derail NASA's ability to sustain its long-term human exploration goals of the moon and Mars."ĭespite these issues, NASA officials insist that the American public will find the cost of the rocket - which they say will kickstart a new era of space exploration - to be justified. "Given our estimate of a $4.1 billion per-launch cost of the SLS/Orion system for at least the first four Artemis missions, NASA must accelerate its efforts to identify ways to make its Artemis-related programs more affordable," Martin said at a March 1 testimony before the House Subcommittee on Space and Aeronautics. taxpayers back by $93 billion by the end of 2025, according to the office of NASA inspector general Paul Martin - the space agency's internal auditor. The program, which began in 2017, has already cost more than $40 billion to develop and is projected to knock U.S. NASA is banking heavily on a successful mission for Artemis 1, which has come under scrutiny for a price-tag that has ballooned to eye-watering levels. As this would probably mean delaying the launch for several months, Honeycutt said that his team was looking into creating a workaround plan that would enable flight engineers to make an "informed decision" on whether the rocket could take off without taking readings from the sensor. The faulty sensor cannot be easily replaced, and swapping it out would likely mean the rocket has to be rolled back to NASA's Vehicle Assembly Building for a thorough investigation. ![]() "The way the sensor is behaving does not line up with the physics of the situation," John Honeycutt, NASA's program manager for the Artemis 1 mission, said at the news conference. NASA will attempt to fix this issue for Saturday afternoon's launch by performing the engine chilling procedure half an hour earlier - a trick officials say was effective during a successful test conducted last year.Īnd the engine may not have trouble cooling at all NASA scientists have suggested a faulty temperature sensor may have falsely reported the temperature inside the engine as being much higher, and much further from flight-ready, than it actually was. The problematic engine, named engine three, appeared to be around 40 degrees Fahrenheit (22 degrees Celsius) warmer than the temperature of minus 420 F (minus 250 C) needed for launch. ET, when the team declared that the liquid hydrogen fuel was only cooling three of the rocket's four engines to sufficient temperatures prior to ignition. The issue that finally scuppered the launch arrived just after 6 a.m. Another snag for Monday’s failed launch came when engineers spotted a suspected crack in the rocket's thermal insulation, although it was later deemed to be superficial. These problems are reminiscent of those the team reported having during April's wet dress rehearsal, where a faulty helium valve and a liquid hydrogen leak prevented the rocket from being prepared to the point of ignition, Live Science previously reported. ET, the launch team announced it was having problems filling the rocket with supercooled liquid hydrogen fuel. Initial fueling attempts hit delays in the early hours of Monday morning when lightning, which had already struck the Artemis rocket pad two days before, threatened to zap the rocket again. ET, but the attempt was plagued with problems from the beginning. Monday's launch was scheduled for 8:33 a.m. Artemis 2 will make the same journey as Artemis 1, but with a four-person human crew, and Artemis 3 will send the first woman and the first person of color to land on the moon's south pole. ![]() The upcoming uncrewed Artemis 1 test flight - part of the Artemis program named after the twin sister of the ancient Greek god Apollo - will be followed by Artemis 2 and Artemis 3 in 20/2026 respectively. NASA views this flight as the first of three missions that will be a vital testbed for the hardware, software and ground systems that are intended to one day transport the first humans to Mars and beyond. ![]()
