The mission includes a flyby of Neptune and measurements of the heliosphere, the electrically charged gas bubble surrounding our solar system
Defending the planet from the hazard of potential asteroid impacts requires investments from the whole world. In Europe, the European Space Agency (ESA) and the European Union both support work to understand and mitigate the threats from near-Earth objects.
NASA used to spend more on travel for its employees at headquarters than it did on finding dangerous near-Earth asteroids. Now it’s building asteroid-hunting space telescopes. What changed?
A new issue of The Planetary Report brings you our pride in the success of LightSail 2 and our gratitude to our members for making it happen. Plus Venus science from Akatsuki and Venus Express, and the status of planetary defense.
Vishnu Reddy delivers a sober but hopeful report on our understanding of near-Earth objects, their dangers, and our readiness.
Japan's sample return spacecraft only has about 3 months left at asteroid Ryugu. Its next action will be to drop more stuff on the surface.
The LSST is expected to increase the number of known small bodies by more than a factor of 10.
The sites each have unique characteristics that would advance the field of asteroid science.
JAXA's sample collection spacecraft touched down just 60 centimeters away from its aimpoint.
Japan's Hayabusa2 spacecraft has touched down on Ryugu for a second time, bagging samples which hopefully contain material from the subsurface of the asteroid.
Last week, NASA’s OSIRIS-REx asteroid sample-return mission announced that they had achieved an orbit above asteroid Bennu with an altitude of only 680 meters. Now they are surveying for landing sites and have invited the public's help.
IN THE EARLY hours of 22 February, light was just beginning to brighten the campus of JAXA’s Institute of Space and Astronautical Sciences (ISAS) in Kanagawa, Japan. It should have been a quiet time, but the Hayabusa2 control room was packed with people. We were about to land on an asteroid.
Rosetta is a European Space Agency mission with contributions from its member states and NASA. Operating such a complex mission with its 11 instruments and Philae lander is a success story in itself, but Rosetta’s greatest success is the science it delivered.
The reflective softball-sized sphere will give the spacecraft a visual guide during a second potential sample collection.
Gonggong is the fan favorite name for this icy distant world, but the International Astronomical Union's (IAU) Committee for Small-Body Nomenclature has the final say.
The spacecraft is healthy and safe, but time is running out to collect a second sample from asteroid Ryugu.
NASA's OSIRIS-REx spacecraft is currently sweeping arcs between the asteroid's north and south poles.
Hayabusa2's SCI experiment fell toward Ryugu for 40 minutes before detonating about 300 meters above the surface.
It’s time to give 2007 OR10 a name. We’re asking for your help to pick a suitable name for the largest as-yet-unnamed solar system world to submit to the International Astronomical Union (IAU).
Hayabusa2 successfully used its explosive-packed SCI experiment to create an artificial crater on asteroid Ryugu.
