NASA announced that the science mission is likely to last more than 10 years, more than double the minimum time for the mission, after the successful launch of the James Webb Space Telescope.

The telescope will likely have enough propellant to support scientific operations for even longer, according to NASA. The extra propellant is thanks to the Ariane 5 rocket that was used to launch the JWST. The first and second mid-course correction maneuvers have been performed in the days since the launch and have set the craft on a path toward its destination a million miles from Earth.

NASA says that the precision of these maneuvers leaves the craft with more propellant to maintain its final position. The space agency warns that many factors could affect the lifespan of JWST.

The potential extension of scientific research is similar to the Hubble telescope. The Hubble telescope is still operating more than 30 years after NASA projected it would last 15 years. The Hubble Space Telescope was able to be serviced by astronauts, while the JWST is not. Hubble can see objects 10 to 100 times fainter, but the JWST can see objects 10 to 100 times fainter.

The launch trajectory allowed for the early deployment of the solar array. The deployment of the solar array was scheduled to begin about 33 minutes after the Ariane 5 rocket left the ground. NASA said in a press release that it happened about 29 minutes after the launch. NASA says that future deployment of the solar array are going to be human controlled.
