NASA is preparing to slam a spacecraft into an asteroid at 16,000 miles per hour, in a pioneering attempt to nudge it off course. But the yearlong mission scheduled to begin on Nov. 24 is raising an existential question for scientists and security experts: whose job is it to defend the planet against a possibly life-ending space rock if one was headed our way?

NASA's Perseverance rover has socked away another Martian sample to send home to Earth. The car-sized Perseverance rover drilled a core sample on Monday (Nov. 15), filling a titanium tube with Red Planet rock for the third time ever.

The debris from the missile test 'will continue to pose a threat to activities in outer space for years to come, putting satellites and space missions at risk'

Putting boots on the moon is an expensive proposition. NASA's spending on its Artemis program, which aims to establish a sustainable human presence on and around the moon by the end of the decade, is projected to reach a total of $93 billion by 2025, according to a new audit by the NASA Office of Inspector General (OIG).

The journey back to Earth from space is never easy, but the astronauts aboard the SpaceX capsule coming home Monday will have an extra challenge to deal with: no working toilet. The four members on SpaceX Crew Dragon Endeavor will be wearing diapers as they splash down, in order to prevent anything else from splashing too.

Engineers begin assembling the rocket that will send to orbit the successor to the Hubble telescope.

Research and architecture studio AI Space Factory has designed a 3D-printed house for the surface of Mars – and it looks like a beehive. Dubbed the Marsha Project, the vertical dwelling was dreamt up for NASA’s 3D Printed Habitat Challenge, and has been endorsed by the agency.

Move over, Tang, there’s a new space snack in orbit. And this one is made from fresh ingredients grown in zero gravity.

NASA is aiming to fly its massive next-generation rocket, the Space Launch System (SLS), for the first time in February 2022, a critical test flight on the US space agency’s journey to send people back to the Moon.

SpaceX has taken a major step towards sending the Starship to orbit. On Thursday night, the private space corporation has conducted the SN20 Starship prototype's first static fire test as part of its preparation for the spacecraft's launch. According to Space, the SN20 is currently outfitted with two Raptor engines: A standard "sea-level" Raptor and a vacuum version designed to operate in space.

SpaceX's SN20 Starship prototype just took its first fiery breath. SpaceX conducted a brief engine test at its South Texas facilities last night (Oct. 18) with SN20, which the company is prepping to make the Starship program's first-ever orbital test flight.

A Russian film crew are back on Earth after wrapping up scenes for the first movie shot in space. Klim Shipenko and actor Yulia Peresild left the International Space Station and landed in Kazakhstan - to be met by a crew filming touchdown scenes. The ISS shooting was not without drama - suitable for a film called Challenge.

While the astronauts were said to not be in any danger, it was the second such incident since July.

Attention asteroid aficionados: NASA is set to launch a series of spacecraft to visit and even bash some of the solar system's most enticing space rocks. The robotic trailblazer named Lucy is up first, blasting off this weekend on a 12-year cruise to swarms of asteroids out near Jupiter—unexplored time capsules from the dawn of the solar system. And yes, there will be diamonds in the sky with Lucy, on one of its science instruments, as well as lyrics from other Beatles' songs.

China urged relevant foreign space agencies and organizations to pay attention to the data on the Chinese spacecraft that are kept updated on the website of the China Manned Space Agency (CMSA) to avoid possible space collisions and ensure the safety of Chinese taikonauts, a spokesperson of the CMSA said on Thursday during a press briefing prior to Shenzhou-13's launch.

The Star Trek actor William Shatner declared himself “overwhelmed” at becoming the oldest human in space, at the age of 90, during a brief but successful second crewed flight on Wednesday of Blue Origin’s New Shepard rocket ship from the west Texas desert.

Russia plans to slash funding for spaceflight activities during the coming three-year period, from 2022 to 2024. The cuts will come to about 16 percent annually, several Russian publications, including Finanz.ru, report. (These Russian-language articles were translated for Ars by Rob Mitchell.)

Announced on April 5, Aurora Station will hold up to four guests at a time 200 miles above the Earth's surface come 2022 (if everything goes as planned).

William Shatner is preparing for a trip to space aboard Jeff Bezos' Blue Origin rocket, according to reports. TMZ first reported that the actor who played Captain Kirk on "Star Trek" is expected to blast off on an upcoming October civilian flight in the New Shepard capsule. It has not yet been announced who will join him.

As humanity ventures farther and farther away from Earth, space agencies will need to ensure that astronauts can operate autonomously, because any transmissions to and from mission control will face longer and longer delays.
