NASA's Roman Space Telescope may stay operational for at least 22 years, according to a ScienceDaily report. That would more than double the observatory's original 10-year design life, giving astronomers a longer window for wide-field infrared surveys.
The longer mission is possible because of a combination of factors: an extremely precise course correction after launch, extra fuel carried on board, and expected savings from careful fuel use. These leave the telescope with a larger reserve than originally planned.
The report does not describe any changes to the telescope's instruments or science goals. Instead, the extra time would let Roman continue its planned surveys well beyond the initial mission window.
