NASA’s big plans to explore small bodies

Asteroids have been orbiting the sun for thousands of millennia in deep space, standing as ancient storytellers, holding clues about the formation of the solar system. NASA’s first mission to collect a sample from an asteroid, the Origins, Spectral Interpretation,

Tunguska explosion in 1908 caused by asteroid grazing Earth?

A new theory explains the mysterious explosion in Siberia, scientists say, suggesting Earth barely escaped a far greater catastrophe.

In the early morning of June 30, 1908, a massive explosion flattened entire forests in a remote region of Eastern Siberia along the Tunguska River.

Scientists peer inside an asteroid

New findings from NASA’s OSIRIS-REx mission suggest that the interior of the asteroid Bennu could be weaker and less dense than its outer layers – like a creme-filled chocolate egg flying though space.

The results appear in a study published in the journal Science Advances and led by the University of Colorado Boulder’s OSIRIS-REx team,

NASA’s OSIRIS-REx unlocks more secrets from Asteroid Bennu

NASA’s first asteroid sample return mission now knows much more about the material it’ll be collecting in just a few weeks. In a special collection of six papers published in the journals Science and Science Advances, scientists on the OSIRIS-REx mission present new findings on asteroid Bennu’s surface material,

Second Alignment Plane of Solar System Discovered

A study of comet motions indicates that the solar system has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that the aphelia of the comets, the point where they are farthest from the Sun, tend to fall close to either the well-known ecliptic plane where the planets reside or a newly discovered “empty ecliptic.”

Ryugu’s rocky past laid bare

The asteroid Ryugu may look like a solid piece of rock, but it’s more accurate to liken it to an orbiting pile of rubble. Given the relative fragility of this collection of loosely bound boulders, researchers believe that Ryugu and similar asteroids probably don’t last very long due to disruptions and collisions from other asteroids.

OSIRIS-REx finds possible pieces of Vesta on Bennu

In an interplanetary faux pas, it appears some pieces of asteroid Vesta ended up on asteroid Bennu, according to observations from NASA’s OSIRIS-REx spacecraft. The new result sheds light on the intricate orbital dance of asteroids and on the violent origin of Bennu,

Astronomers Have Discovered a 2-km Asteroid Orbiting Closer to the Sun than Venus

Astronomers have painstakingly built models of the asteroid population, and those models predict that there will be ~1 km sized asteroids that orbit closer to the Sun than Venus does. The problem is, nobody’s been able to find one. Until now.

New small satellite mission to rendezvous with binary asteroids

The University of Colorado Boulder and Lockheed Martin will soon lead a new space mission to capture the first-ever closeup look at a mysterious class of solar system objects: binary asteroids.

These bodies are pairs of asteroids that orbit around each other in space,

How small particles could reshape Bennu and other asteroids

In January 2019, NASA’s OSIRIS-REx spacecraft was orbiting asteroid Bennu when the spacecraft’s cameras caught something unexpected: Thousands of tiny bits of material, some just the size of marbles, began to bounce off the surface of the asteroid – like a game of ping-pong in space.
