The physics of undulatory human swimming

A research team led by the University of Tsukuba created the most complete recording to date of a human swimming underwater like an eel or lamprey. Using motion-capture equipment and particle velocity monitors, the scientists ...

Enabling longer space missions

The 50th anniversary of the Apollo 11 moon landing has reignited interest in space travel. However, almost any mission beyond the moon, whether manned or unmanned, will require the spacecraft to remain fully operational for ...

BepiColombo is ready for its long cruise

Following a series of tests conducted in space over the past five months, the ESA-JAXA BepiColombo mission has successfully completed its near-Earth commissioning phase and is now ready for the operations that will take place ...

Levitating objects with light

Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects' surfaces.

New technology helps address big problems for small satellites

CubeSats have become big players in space exploration. Their small size and relatively low cost have made them popular choices for commercial launches in recent years, but the process to propel such satellites in space comes ...

Ion drive space engine used on aircraft for first time

Imagine an aircraft engine that has no moving parts, produces no harmful exhaust and makes no noise. That's what researchers at the Massachusetts Institute of Technology (MIT) in the US have created by adapting a technology ...
