JAXA announced its success and its worrying technical problem shortly after noon, ET. Two hours earlier, tens of thousands of people watched a video livestream as SLIM's lunar altitude ticked down ...

Witness NASA and JAXA’s 19-inch X-59 scale model hit Mach 1.4 (925 mph) in Tokyo’s wind tunnel as researchers chase a quieter sonic thump.

The Japan Aerospace Exploration Agency is launched an X-ray satellite to study extreme cosmic objects and a lunar lander nicknamed the “Moon Sniper” on Wednesday evening.

If JAXA does unjam its door, Chandra will be an important tool to follow up XRISM's observations. Meanwhile, the ghosts of Suzaku and Hitomi will linger until the next attempt at opening the door.

JAXA officials remain optimistic that SLIM could revive in about one week, when, during the two-week lunar afternoon, the sun will be shining from the west, illuminating the solar panels.

JAXA isn't particularly adept at showmanship and bravado, and it often wears humility like armor, but it's exactly for these reasons that its little corner of Tokyo remains peaceful.

The developers plan to hand the satellite, made from magnolia wood and named LignoSat, to space agency JAXA next week. It will be sent into space on a SpaceX rocket from the Kennedy Space Center ...
