NASA’s James Webb Space Telescope may not launch on Halloween (Oct. 31) after all. Despite previous delays, progress on the highly anticipated Webb—billed as the successor to the iconic Hubble Space Telescope—has been steadily ongoing. The telescope is set to be shipped in August to Kourou, French Guiana, where Webb will launch to space atop an Arianespace Ariane 5 rocket from the Guiana Space Center. However, while takeoff has been slated for Oct. 31, it seems that the launch might not happen until the following month. Thomas Zurbuchen, NASA’s associate administrator for the science, confirmed the timeframe suggestion, but did not explicitly state a new launch date.
