Researchers Test New Mars Spacesuits

To support Mars exploration, new spacesuits must protect astronauts, supply air and water, and be flexible enough to allow for small required tasks like the digging of samples. Engineers from the University of North Dakota are evaluating new spacesuit design at Kennedy Space Center.

Sponge-Like Material Soaks Up Oil Spills

In hopes of limiting the disastrous environmental effects of massive oil spills, scientists from Drexel University and Deakin University, in Australia, have teamed up to manufacture and test a new material. The boron nitride nanosheet absorbs up to 33 times its weight in oils and organic solvents — a trait that supports the quick mitigation of costly accidents.

Single-Layer Material Mimics Photosynthesis

A Florida State University researcher has discovered an artificial material that mimics photosynthesis and potentially creates a sustainable energy source. The new material efficiently captures sunlight; then, the energy can be used to break down water into oxygen (O2) and hydrogen (H2).

Self-Healing Spacecraft Material Plugs Holes in Seconds

Although shields and sophisticated maneuvers could help protect space structures, scientists have to prepare for the possibility that debris could pierce a vessel. NASA and a team from the University of Michigan developed a new material that heals itself within seconds and could prevent structural penetration from being catastrophic.

'Snap' Design Mimics Venus Flytrap

A team led by physicist Christian Santangelo at the University of Massachusetts Amherst uses curved creases to give thin shells a fast, programmable snapping motion. The technique – inspired by the natural "snapping systems" like Venus flytrap leaves and hummingbird beaks – avoids the need for complicated materials and fabrication methods when creating structures with fast dynamics.
