Nasa has selected 17 technology demonstration projects for reduced-gravity aircraft flights.
The projects will determine if emerging technologies can perform as expected in the reduced-gravity environment of the moon and Mars, or in the zero-gravity environment of Earth’s orbit.
The projects include monitoring human health, managing liquid propellants in zero gravity, manoeuvring vehicles, assembling structures and manufacturing in space.
Other experiments will test components for new types of space propulsion, life support systems and tools for advanced biological research.
Several projects deal with methods to process resources on the moon.
Nasa selected the projects under its facilitated access to the space environment for technology (FAST) programme.

Don’t let policy changes catch you off guard. Stay proactive with real-time data and expert analysis.
By GlobalDataThrough FAST, the agency will incorporate new technologies into its flight programmes and other commercial aerospace applications.
The programme, which is in its third year, will use a commercial aircraft flying up to 40 reduced-gravity parabolas a day for four days in September, operating from Ellington Field in Houston.
