Live coverage: Three Chinese astronauts return to Earth

A Chinese communications satellite carrying a Dutch radio astronomy instrument launched last month is expected to maneuver into position around a gravitationally-neutral point beyond the moon in the coming days, ready to relay telemetry and data between Earth and the Chang’e 4 lander set to attempt the first landing on lunar far side late this year.

A senior NASA official raised concerns Wednesday that “difficulties” with SpaceX’s development of the huge new Starship rocket could delay the Artemis program’s first moon landing with astronauts from late 2025, a mission that will use a derivative of the Starship vehicle to ferry a two-person crew to and from the lunar surface.

China launched a high-altitude satellite Monday fitted with a powerful telescope to collect nearly continuous imagery of the Asia-Pacific from geostationary orbit, an apparently unique capability that could help track foreign naval activity, according to Chinese news reports.
