Astronauts problems of prolonged exposure to micro gravity are: spine elongation, high feat pressure sensitivity, weakening of bones and muscles, decreased blood flow in limbs and other problems. Our solution: Constant pressure on spine and chest with rubber bands or pulsating pressure vest.

This project is solving the Space Wearables: Designing for Today’s Launch & Research Stars challenge.


Astronauts problems of prolonged exposure to micro gravity are:

Spine elongation because of gravity absence and months of back pain after returning to earth. Increased feat pressure sensitivity developed in micro gravity and after returning to Earth sensation like walking on needles. Weakening of bones and muscles, bone density and muscles volume. Facial puffiness because of blood pressure equalization in a body. Decreased blood flow in limbs. Other problems.

Our solution is - Anti Gravity (gravity) Astronaut Suit „AGAS“ :

Constant pressure on spine and leg bones (18h/day) rubber bands with pressure force adjuster, from shoulders to the foot with straps on the leg muscles. Constant pressure on chest (18h/day) pressure vest with pressure force adjuster, alternative solution: additional vest pulse pressure compression in accordance with breathing with pressure force adjuster. Embedded sensors for blood pressures, temperature, Smart watch for pulse measuring with WiFi audio, visual and data communication in station between astronauts, ground, extravehicular activity (EVA-s) and capsule-station.

In this low cost prototype model (produced in a 2 hours for NASA-s Space App Challenge 2015): 22 pounds of constant force on spine and legs (11 pounds of force per leg). 11 pounds of constant force on a rib cage. For astronauts height of 5' 9".
