A new analyze tested this theory on a spaceflight simulation chamber on Earth with 16 people today: 10 gentlemen and 6 women of all ages.
4 persons participated in every single 45-day, Earth-dependent, closed-chamber mission. They both ate a normal astronaut food plan or 1 that was enhanced with far more fruits and greens, together with more fish and other sources of omega-3 fatty acids.

The report was printed on line a short while ago in Scientific Reviews.
This improved spaceflight diet plan has considerable wellbeing and functionality positive aspects, reported research writer Grace Douglas, superior food stuff know-how lead scientist for NASA in Houston, and colleagues. It may possibly be effective for astronauts, even on shorter area missions, the study staff mentioned in a journal news launch.
All of the foodstuff ended up shelf-stable, which is a ought to to meet storage disorders on place missions. The food items was stored in the chamber in advance of the get started of each and every mission.
Individuals supplied samples of their saliva, urine, blood and stool, and done cognitive assessment responsibilities all through the missions.
