What part of a space rock survives all the way to the ground?

When a small asteroid enters Earth's atmosphere from space, its surface is brutally heated, causing melting and fragmenting. Therefore, why the rocks near the surface survive to the ground as meteorites has been somewhat ...

Image: Pure gold pin for space testing

Although this pure gold pin is not much bigger than the tip of a pencil, it is the "pulsing heart" of ESA's Low Earth Orbit Facility, LEOX. Part of the Agency's Materials and Electrical Components Laboratory, based at ESA's ...

Video: Does space trash ever naturally break down?

Remember when Elon Musk launched a car into space? That car's not just peacefully drifting through a vacuum—it's hurtling around the sun at 63,592 miles per hour, being bombarded by solar radiation. It might be in pieces, ...

A primary standard for measuring vacuum

A novel, quantum-based vacuum gauge system invented by researchers at the National Institute of Standards and Technology (NIST) has passed its first test to be a true primary standard—that is, intrinsically accurate without ...

Scientists identify a possible source for Charon's red cap

Southwest Research Institute scientists combined data from NASA's New Horizons mission with novel laboratory experiments and exospheric modeling to reveal the likely composition of the red cap on Pluto's moon Charon and how ...

'Fruitcake' structure observed in organic polymers

Researchers have analyzed the properties of an organic polymer with potential applications in flexible electronics and uncovered variations in hardness at the nanoscale, the first time such a fine structure has been observed ...
