- 1Roman Telescope's Fuel Savings Double Its Mission Life●"Roman Telescope Saves Fuel, Doubles Mission" by @ hackaday - Several factors have added up to extend # NASA # RomanSpac
NASA's Nancy Grace Roman Space Telescope has had its expected mission duration extended from 10 to 22 years after engineers found the spacecraft carries significantly more propellant than planned. Efficient construction and launch factors left unused fuel margin, allowing the wide-field survey telescope to operate far longer than its baseline design.
- 2NASA telescope project moves forward with three Johns Hopkins members▼NASA space telescope project advances with three Hopkins team members
Johns Hopkins University reports that three of its team members are taking part in a NASA space telescope project that is moving ahead. The university announced the involvement of the Hopkins researchers as the project advances, though details on their specific roles and the mission timeline were not provided in the announcement.

China's Einstein Probe satellite is drawing attention for its unusual wide-field view of the X-ray universe. The spacecraft uses 'lobster eye' optics, a design inspired by how lobsters' eyes reflect light, allowing it to monitor a large swath of the sky at once. That means any sudden, violent X-ray event, such as a supernova or a feeding black hole, is likely to be caught quickly, giving astronomers worldwide rapid alerts to follow up with telescopes.
- 4Comet 161P/Hartley-IRAS tracked ahead of perihelion●2026-10-01 04:00:00 UTC (Delta: 2026-09-30) ☄️161P/HARTLEY-IRAS - Barycentric speed: 32.82 km/s (+0.09 km/s) - Perihelio
Comet 161P/Hartley-IRAS is being monitored as it moves toward the inner solar system. Its barycentric speed has ticked up to 32.82 km/s, with perihelion about 57 days away. Current brightness sits around magnitude 14.2, meaning it remains a small-telescope target from dark-sky sites, currently in the constellation Aquarius and visible from both hemispheres. Amateur astronomers are following its gradual brightening as the approach continues.
- 5NASA telescope to burn up in atmosphere after failed rescue●NASA space telescope to burn up in Earth’s atmosphere after failed rescue attempt
NASA says one of its space telescopes will burn up in Earth's atmosphere after a rescue attempt to save it failed. The mission to recover or reposition the telescope did not succeed, and the spacecraft is now expected to be destroyed during reentry, closing out its time in orbit.
