Engineers teach spacecraft to ‘dream’ their way to the space station

Docking with the ISS may seem simple. However, actually doing so shows how difficult orbital mechanics can be. It’s like traveling down a highway at 28,000 km/hr (17,000 mph) and parallel parking in an open garage on a multibillion-dollar laboratory traveling at the same speed. If you try to accelerate forward, you actually drift up, and there’s no air friction to naturally slow you down. Oh, and if you hit the lab, everyone aboard both your craft and the station dies, and the resulting debris field could wipe out dozens of satellites and even harm people on the ground. No pressure, obviously.

For decades, aerospace engineers have docked successfully using hard-coded physics equations and human pilots to make correc...

Wristwatch-like device enables assessment of health risks for astronauts on mission to the moon

Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit the moon in half a century would carry a device developed by Okamoto and his team at Condor Instruments, a São Paulo-based startup.

“The NASA announcement was sudden and caught us by surprise...

Space mice come home and start families

Four mice went to space as astronauts. One came back and became a mother. And that simple fact might matter more than you’d think for humanity’s future beyond Earth.

On 31 October, China launched four mice numbered 6, 98, 154, and 186, aboard the Shenzhou-21 spacecraft to the country’s space station, roughly 400 kilometers above Earth. For two weeks, the rodents lived in microgravity, exposed to space radiation and the peculiar conditions of orbital life. They returned safely on 14 November. Then, on 10 December, one of the females gave birth to nine healthy pups.

In a previous study, sperm from mice that had been in space had been used to fertilize female mice back ...

Astrobee learns to transport soft cargo: Open-source simulator models real ISS challenges

Astrobee is a free-flying robotic system developed by NASA that is made up of three distinct cube-shaped robots. This system was originally designed to help astronauts who are working at the International Space Station (ISS) by automating some of their routine manual tasks.

While Astrobee could be highly valuable for astronauts, boosting the efficiency with which they complete day-to-day operations, its object manipulation capabilities are not yet optimal. Specifically, past experiments suggest that the robot struggles when handling deformable items, including cargo bags that resemble some of those that it might be tasked to pick up on the ISS.

Researchers at Stanford University, University of Cambridge and NASA Ames recently developed Pyastrobee, a simulation environment and co...
