highly anticipated Europa Clipper probe bound for an icy moon of Jupiter is on track for its liftoff next month. Europa Clipper, which will study the potentially life-harboring Jupiter moon Europa up close, passed a crucial technical review called Key Decision Point E (KDP-E) today (Sept. 9). The good news means that Clipper can proceed into final preparations for launch, which is scheduled to take place atop a SpaceX Falcon Heavy rocket from NASA's Kennedy Space Center in Florida on Oct. 10.

Partial lunar eclipse of the Harvest Moon: What to know

The Harvest Moon isn't exclusively a September event because the full moon occurring closest to the autumnal equinox gets hung with this moniker. Every few years, October (rather than September) hosts this moon that once was critical to farmers. Before electricity and tractors with lights were used to harvest crops all night long, farmers relied on the Harvest Moon's light to extend workdays when fields were most bountiful.

Astronauts would have been fine on Starliner, NASA says

(NASA)
After more than three months in space, Starliner's 10-day Crew Flight Test (CFT) has finally concluded. The Boeing spacecraft made a successful landing over the weekend, parachuting to a soft touchdown in the dark desert night of White Sands Missile Range in New Mexico, at 12:01 a.m. EDT (0401 GMT) Saturday (Sep. 7). The return marked an end to a long-delayed and issue-ridden mission, which launched with two NASA astronauts, but returned with none. It turns out they would have been totally fine.

As August 2024 set another 20-year high for sunspot numbers on the sun, recent solar flares have yet to top two solar flares from September 2017. One of these flares, which took place seven years ago on Sept. 10 2017, still holds further unbroken records.

The four members of the Polaris Dawn mission, riding aboard SpaceX's Dragon spacecraft "Resilience," climbed into an elliptical orbit with a high point, or apogee, of 870 miles (1,400.7 kilometers) on Tuesday (Sep. 10). They reached the record distance about 15 hours after lifting off at 5:23 a.m. EDT (0923 GMT) from Florida earlier in the day and circling the planet about eight times in an initial orbit of 190 by 1,200 miles (306 by 1,930 km).

China has revealed that its moon-base plans will be rolled out in two distinct phases, eventually creating a series of nodes on the lunar surface and in orbit. The initial roadmap for the International Lunar Research Station (ILRS), jointly led by China and Russia, was unveiled in June 2021. The pair stated plans to build a basic, robotic moon base through five super heavy-lift rocket launches from 2030 to 2035.
