NASA's Roman Space Telescope could last more than twice as long as planned

The Nancy Grace Roman Space Telescope could operate for at least 22 years instead of the planned 10: the first course correction was performed with over 99% accuracy and used 18 kg of fuel out of 200 kg. Fuel savings at launch and the second correction provide about eight more years of operation.

• First course correction used 18 kg of fuel instead of 200 kg
• Maneuver accuracy exceeded 99%
• Fuel savings provide about 8 additional years
• Arrival at L2 is expected in early December
