Chain Drive Dust Conveyer

The Mars 2020 coring drill will generate a significant amount of dust and debris (known as fines) due to the volume of milled material displaced by the corer's annulus. These cuttings must be removed to ensure that the...

BiBlade Sampling Chain

The BiBlade sampler has been developed for potentially acquiring samples from the surface of a planetary body. The tool could conceivably be used in both in situ and notional sample return missions to planetary bodies...

Micro Acoustic Resonant Chambers for Heating/Agitating/Mixing (MARCHAM)

To measure organics in a fluid sample, one either has to bring the sample in the form of a colloid to the instrument, or extract the organics from the sample and bring the...

Compact, Lightweight Trap Vent

This compact, lightweight trap vent is used to minimize the pressure differential of a high-altitude, balloon-borne detector. The vent allows the pressure to equalize rapidly, yet does not allow any light to enter...

Mechanical Actuators Bend as They “Breathe”

Extreme temperatures can severely strain a mechanical component because its material may have trouble enduring the heat without degrading. To address the problem, researchers at MIT developed a new...
