Hayabusa2 Ascends from Asteroid Ryugu
1.11.2018

Will spacecraft Hayabusa2 be able to land safely on asteroid Ryugu? Since arriving in June, pictures show that the surface of kilometer-sized Ryugu is covered with boulders, so that finding a flat enough area for the bus-sized spacecraft to touch down is proving a challenge.

Virtual Flight Over Asteroid Vesta
14.05.2012

What would it be like to fly over the asteroid Vesta? Animators from the German Aerospace Center recently took actual images and height data from NASA's Dawn mission currently visiting Vesta to generate such a virtual movie.

Asteroids in the Distance
16.03.1998

Rocks from space hit Earth every day. The larger the rock, though, the less often Earth is struck. Many kilograms of space dust pitter to Earth daily. Larger bits appear initially as a bright meteor. Baseball-sized rocks and ice-balls streak through our atmosphere daily, most evaporating quickly to nothing.

Orbits of Potentially Hazardous Asteroids
29.08.2021

Are asteroids dangerous? Some are, but the likelihood of a dangerous asteroid striking the Earth during any given year is low. Because some past mass extinction events have been linked to asteroid impacts, however, humanity has made it a priority to find and catalog those asteroids that may one day affect life on Earth.

An Unusual Mountain on Asteroid Ceres
30.06.2015

What created this large mountain on asteroid Ceres? No one is yet sure. As if in anticipation of today being Asteroid Day on Earth, the robotic spacecraft Dawn in orbit around Ceres took the best yet image of an unusually tall mountain on the Asteroid Belt's largest asteroid.

Survivor: NEAR Shoemaker On Asteroid Eros
5.03.2001

Not part of a television game series, the NEAR Shoemaker spacecraft survived its unprecedented landing on an on asteroid last month. As suggested in the illustration inset above, the car-sized probe likely rests gently on the tips of its solar panels having touched down under the influence of asteroid Eros' feeble gravity.

Rosetta Spacecraft Passes Asteroid Steins
8.09.2008

What's that diamond in the sky? Cruising though space, sometimes you'll come across an unusual object. Such was the case on Friday for ESA's Rosetta spacecraft on it's way to comet Churyumov-Gerasimenko in 2014.

Asteroid Ryugu from Hayabusa2
22.08.2018

This big space diamond has an estimated value of over 80 billion dollars. It's only diamond in shape, though -- asteroid 162173 Ryugu is thought to be composed of mostly nickel and iron. Asteroids...

Places for OSIRIS REx to Touch Asteroid Bennu
23.12.2019

Where is the best place to collect a surface sample from asteroid Bennu? Launched in 2016, NASA sent the robotic Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) to investigate the 500-meter-across asteroid 101955 Bennu.
