“The mobile gravity suit is a small, untethered, and flexible intravehicular activity (IVA) suit,” the researchers wrote in their paper published in the Frontiers in Physiology journal.

The idea is to give astronauts maximum flexibility while on board a spacecraft, without reducing crew time. “With the gravity suit, astronauts will be able to float freely around the space station while adhering to their every day tasks,” the paper reads.

“The negative pressure is generated by its own portable vacuum system, ensuring full mobility, and user-control,” the paper reads.
