James Webb Space Telescope’s fuel expected to last more than 10 years

The telescope was projected to operate for 5 to 10 years its science mission is likely to last “significantly more” than 10 years — more than double the minimum time for the mission. Initially, JWST was projected to be operational for 5 to 10 years, but NASA’s latest analysis found that the telescope will likely have enough propellant to support scientific operations for even longer. According to NASA, the extra propellant is thanks to the precision of the Ariane 5 rocket that the JWST was on when it was launched into space. It is also due to the precision of the first and second — small trajectory tweaks that the spacecraft has completed in the days since launching, setting it on a path toward its destination . ........Read more
