From an artificial gravity chamber and a fuel free engine to a Martian airship: NASA funds 22 sci-fi proposals that could ‘expand how we explore the universe’
NASA has revealed several proposals where the space agency is set to invest to take the space exploration even further. While some of these projects will take a significantly longer time before they can be used by NASA, they are set to increase options for further exploration according to the agency.
One of the major proposals is the concept of a “Turbolift” device that would decrease physiological deconditioning astronauts are known to go through. According to the proposal, ‘the astronaut is linearly accelerated at 1G for ~1s, then is rotated 180 degrees to prepare for a 1G deceleration for ~1s.”
‘This process is repeated to create intermittent AG where the force is always headward similar to standing here on Earth.”
‘The experience is likely to be analogous to bouncing mildly on a trampoline.’
Another concept is a vacuum airship that uses its structure to protect the critical instruments from solar radiation and high energy particle according to the proposal. It said, ‘The vacuum airship probe would be able to traverse a much greater area of the planet in a smaller amount of time because there is no need to worry about getting stuck, and the vacuum airship can also observe a greater swath of land by rising in elevation.
‘Even though the vacuum airship would be aerially base, the vehicle would still be able to touch down and perform tasks on the ground; it is even possible the vacuum airship could be used to transport ground probes to different locations.’
While we will need to wait a long period of time, the results can be proven significant in the coming years as space exploration is set to increase even more in the near future.
