![]() ![]() Replacing the sensor would require rolling the rocket back to its assembly building, a process that could delay the mission for months. The sensor was last checked and calibrated months ago in the rocket factory, Honeycutt said. "The way the sensor is behaving doesn't line up with the physics of the situation," said John Honeycutt, NASA's SLS program manager. But a full explanation for the faulty sensor requires more data analysis by engineers. Speaking to reporters on Tuesday, mission managers said they believe a faulty sensor in the rocket's engine section was the culprit for the engine cooling issue.Īs a remedy for Saturday's attempt, mission managers plan to begin that engine-cooling process roughly 30 minutes earlier in the launch countdown, NASA's Artemis launch director Charlie Blackwell-Thompson said. NASA's initial Artemis I launch attempt on Monday ended after data showed that one of the rocket's main-stage engines failed to reach the proper pre-launch temperature required for ignition, forcing a halt to the countdown and a postponement. human spaceflight efforts shifted to low-Earth orbit with space shuttles and the International Space Station. ![]() The long-awaited voyage would kick off NASA's moon-to-Mars Artemis program, the successor to the Apollo lunar project of the 1960s and '70s, before U.S. If all goes as hoped, the SLS will blast off from the Kennedy Space Center in Cape Canaveral, Florida, on Saturday afternoon, during a two-hour launch window that opens at 2:17 p.m., sending the Orion on an uncrewed, six-week test flight around the moon and back. In that way, the launch exercise was serving essentially as a real-time dress rehearsal that hopefully would conclude with an actual, successful liftoff.įor now, NASA officials said, plans call for keeping the 32-story-tall Space Launch System (SLS) rocket and its Orion astronaut capsule on its launch pad to avoid having to roll the massive spacecraft back into its assembly building for a more extensive round of tests and repairs. ![]() Register now for FREE unlimited access to Register ![]()
