WASHINGTON: DARPA’s effort to develop nuclear ‘engines’ for far-roving satellites also hopes to demonstrate the capability to keep “timely” tabs on spacecraft operating near the Moon, says program manager Maj. Nathan Greiner.
While cislunar surveillance doesn’t require nuclear-propulsion, such a spacecraft could move more rapidly into position to monitor targets of interest. It might also mean the spacecraft would be able to remain active for a longer period thanks to the fuel.
“Some of this is classified, so this answer must be rather general,” he said in an email, explaining that the Demonstration Rocket for Agile Cislunar Operations (DRACO) program has two key goals: ....

China's Chang'e 5 moon craft on a new mission: the sun | Space


January 22, 2021
China’s Chang’e 5 moon mission successfully returned moon rocks to Earth in December 2020 for the first time in 45 years. It’s now headed toward an Earth-sun Lagrange point, with the goal of making sun observations.
ChinaDaily reported this week (January 20, 2021) that the Chang’e 5 moon craft – which on December 16-17 dropped off its return capsule, returning moon rocks to Earth for the first time since 1976 – is now on a new mission to observe the sun. That’s after an earlier report on December 22, saying the same thing. The news may be that mission engineers originally overestimated the amount of fuel remaining to Chang’e. In December, they were estimating 440 pounds (200 kg) of fuel left. Now, as explained in the video above, space engineers are reporting just 220 pounds (100 kg) of fuel remaining. The fuel is needed to insert Chang’e into an orbit at an Earth-sun Lagrange point (L1) when it arrives there in mid-March. ....
