When shifting from the microgravity of a spacecraft to the gravity-rich environment of the moon or Mars, astronauts experience deficits in perceptual and motor functions. The vestibular system in the inner ear, which detects the position and movement of the head, must adjust to reinterpret new gravity cues.

A University of Michigan-led team, including researchers from the University of Colorado Boulder's Bioastronautics Lab and NASA's Neuroscience Lab at Johnson Space Center, developed a multidirectional tapping task administered in augmented reality (AR) to detect sensorimotor impairments similar to those observed in astronauts after spaceflight.

The results, published in Aerospace Medicine and Human Performance, could support mission operations decisions by establishing when astronauts are able to perform tasks that require full coordination, like piloting vehicles or operating other complex systems.

Field tests to assess sensorimotor impairment have previously been conducted upon the return of International Space Station crew members to Earth.

On October 19th, 2017, astronomers with the Pann-STARRS survey observed an interstellar object passing through our system—1I/2017 U1 'Oumuamua. This was the first time an ISO was detected, confirming that such objects pass through the solar system regularly, as astronomers predicted decades prior. Just two years later, a second object was detected, the interstellar comet 2I/Borisov. Given 'Oumuamua's unusual nature (still a source of controversy) and the information ISOs could reveal about distant star systems, astronomers are keen to get a closer look at future visitors.

For instance, multiple proposals have been made for interceptor spacecraft that could catch up with future ISOs, study them, and even conduct a sample return (like the ESA's Comet Interceptor).

The first U.S. spacecraft to land on the moon since the Apollo astronauts fell silent Thursday, a week after breaking a leg at touchdown and tipping over near the lunar south pole.

Intuitive Machines' lander, Odysseus, lasted longer than the company anticipated after it ended up on its side with hobbled solar power and communication.
