![]() ![]() "I am confident the team will do everything they can to prepare Webb to explore our cosmic past," he wrote on Twitter. NASA's science chief, Thomas Zurbuchen, said Monday it was important for NASA to ensure the telescope was healthy before its launch. NASA has had a difficult time testing them all on Earth in conditions that mimic the temperatures, pressure, and microgravity of deep space. This is an exceedingly complex process, and there are more than 300 single points of failure aboard the observatory. Since then, technical problems and delays have bedeviled the complex telescope.īuilding Webb has been difficult because its 6.5-meter mirror needs to unfurl itself once it reaches an orbit about 1.5 million kilometers from Earth. In a news conference Thursday, NASA officials. A senior source at the space agency said this testing is currently running ahead of schedule and that, provided some serious issue is not identified, the December 22 launch date should stick.Īny setbacks now in Webb's progress toward launch feel especially painful because reaching this point has been such a long, long road. NASA's follow-on instrument to the wildly successful Hubble Space Telescope was originally due to launch about a decade ago, with a development cost of $1 billion. The James Webb Space Telescope, which was proceeding toward a launch date of March 2021, will now be launched no sooner than Oct. The launch of the craft has been long-awaited. NASA said it will provide an update when the testing is completed at the end of this week. 2 min read (Getty Images/iStockphoto) Nasa will be launching the James Webb Space Telescope on Christmas Day.Launched in December 2021, the spacecraft has been in a halo orbit around the second SunEarth Lagrange point (L 2), about 1.5 million kilometers (900,000 mi) from Earth, since January 2022. NASA is leading an anomaly review board to investigate and conduct additional testing to determine with certainty that the incident did not damage any part of the telescope. The James Webb Space Telescope is a space telescope operated by NASA and designed primarily to conduct infrared astronomy.
