There is no easy means of servicing the telescope at its location near a Sun-Earth LaGrange point 1.5 million km from Earth, or four times the distance to the Moon. All of these systems must work or the instrument will fail. To the frustration of scientists and policymakers, myriad technical problems have delayed Webb's development over the last decade, leading to enormous cost overruns. Some of this is understandable, as unfurling the 20-meter-long telescope in deep space requires 50 major deployments and 178 major release mechanisms. Why is NASA's most expensive scientific instrument ever launching on a European rocket? Because the European Space Agency is conducting the launch for NASA in return for a share of observation time using the infrared telescope. Webb will observe wavelengths of light longer than those of the Hubble Space telescope, and this should allow the new instrument to see the earliest galaxies of the Universe. The space telescope will launch on an Ariane 5 rocket. The upcoming launch of the James Webb Space Telescope (JWST) will open new astronomical frontiers, and students at CAS in collaboration with STScI staff will be. The date was announced on Wednesday by NASA, the European Space Agency, and the launch provider, Arianespace. While scanning a region of the cosmos near the Big Dipper, a group of astronomers identified six faint objects as they appeared well over 13 billion years. But they certainly didnt anticipate this. Now, the oft-delayed $10 billion telescope has an official launch date: December 18, 2021. Scientists expected the James Webb Space Telescope to reveal unknowns in the deepest realms of space. It is destined for a point in space 1.5 million kilometres from Earth too. NASA announced in August that the James Webb Space Telescope had passed its final ground-based tests and was being prepared for shipment to its launch site in Kourou, French Guiana. NASA's James Webb Space Telescope deploys its solar array after separating from its Ariane 5 rocket following its launch on Dec. Now, 32 years after its conception, Webb is finally sitting at the spaceport in Kourou in preparation for launch.
