The Space Launch System megarocket that will fly NASA's Artemis 1 moon mission is at the pad for a critical series of tests this weekend.
Here's NASA update ahead of those tests, which together comprise a launch simulation known as a "wet dress rehearsal." It's NASA's latest attempt to actually fuel the rocket.
On Monday, NASA's Perseverance rover snapped a photo of a shiny silver object wedged between two rocks on the floor of the Red Planet's Jezero Crater, which the car-sized robot has been exploring since its February 2021 touchdown.
This space trash is not native to Mars; Perseverance hauled it from Earth, the rover's handlers said.

The destination for NASA's Artemis 1 mission looks big and bright in stunning new photos from the agency taken Tuesday.
In the new images, the full moon looms large behind Launch Complex 39B at NASA’s Kennedy Space Center in Florida. In the foreground is the agency's first Space Launch System (SLS) megarocket, which is scheduled to launch the uncrewed Artemis 1 mission around the moon later this year.
The fastest-growing black hole ever seen is swallowing the mass equivalent of an entire Earth every second.
This gargantuan black hole has a mass 3 billion times that of the sun, and its rapid consumption is causing the behemoth to grow rapidly, an international research team found. The black hole gorges via a process called accretion, in which it siphons matter from a thin disk of gas and dust rotating around the massive object.
A group of anonymous SpaceX employees say that founder and CEO Elon Musk's recent behavior reflects badly on the company.
An open letter to company executives was posted in an internal SpaceX Microsoft Teams channel with more than 2,600 employees, the Verge reported on Thursday (June 16). The letter asks the founder of SpaceX and Tesla to change his ways.
The internet is abuzz with rumors that China may have picked up signals from an alien civilization. But don't get too excited.
"These signals are from radio interference; they are due to radio pollution from Earthlings, not from ET. The technical term we use is 'RFI' - radio frequency interference," one scientist said.
Venus' atmosphere bears no signs of microbes eating or pooping, suggesting that the odd chemical composition of the planet's clouds cannot be explained by extraterrestrial life.
"If life was responsible for the sulfur dioxide levels we see on Venus, it would also break everything we know about Venus's atmospheric chemistry," Sean Jordan, an astronomer at the University of Cambridge and first author of the paper, said in the statement.
