NASA research indicates hunks of frozen carbon dioxide -- dry ice -- may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.

Weightless weak equivalence principle

11-06-2013 02:24 PM CEST

During ten seconds of weightlessness Brynle Barrett from the Laboratory of Photonics, Numerical Sciences and Nanosciences at the University of Bordeaux monitors an experiment to test the 'weak equivalence principle' – or why a feather in a vacuum falls as fast as a hammer.

To confirm that objects in free-fall behave universally, even at a microscopic level, a team of scientists used lasers to cool atoms to around –273°C. On Earth, atoms fall away from laser beams because of gravity. "In microgravity, atoms stay in the beams for much longer, so we get better data," explains Brynle.

Parabolic flights are the only way to run such experiments on humans without leaving Earth's atmosphere. Over the course of multiple roller-coaster flights at up to 45°, researchers find out more about the effects of gravity on experiments and improve equipment destined for space.

John Wargo, lead technician at NASA Glenn's Propulsion System Laboratory (PSL) is performing an inspection on the inlet ducting, upstream of the Honeywell ALF 502 engine that was recently used for the NASA Engine Icing Validation test.

This test allows engine manufacturers to simulate flying through the upper atmosphere where large amounts of icing particles can be ingested and cause flame outs or a loss of engine power on aircraft. This test was the first of its kind in the world and was highly successful in validating PSL's new capability.
No other engine test facility has this capability. Glenn is working with industry to address this aviation issue by establishing a capability that will allow engines to be operated at the same temperature and pressure conditions experienced in flight, with ice particles being ingested into full scale engines to simulate flight through a deep convective cloud.

The information gained through performing these tests will also be used to establish test methods and techniques for the study of engine icing in new and existing commercial engines, and to develop data required for advanced computer codes that can be specifically applied to assess an engine's susceptibility to icing in terms of its safety, performance and operability.
