Stories, updates, insights, and original analysis from The Planetary Society.
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?
Vishnu Reddy delivers a sober but hopeful report on our understanding of near-Earth objects, their dangers, and our readiness.
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.
The LSST is expected to increase the number of known small bodies by more than a factor of 10.
More than 4 years after launch and a half year surveying asteroid Ryugu, Japan's Hayabusa2 spacecraft is ready for sample collection.
Vicky Hamilton explores how OSIRIS-REx used its Earth flyby to test instruments on the way to asteroid Bennu.
OSIRIS-REx team members held a press briefing today at the 2018 American Geophysical Union meeting, and announced that the mission has already found water on asteroid Bennu.
A global team of astronomers has found a rare type of asteroid, where two equal-mass objects circle each other in a never-ending dance as they hurtle through the solar system.
Seven very advanced amateur astronomers will help find, track, and characterize near Earth asteroids.
In a milestone for the mission, JAXA's Hayabusa2 sample return spacecraft has sighted its destination, asteroid Ryugu.
This is the first in a series of posts in which scientists share favorite planetary science plots. For my #FaveAstroPlot, I explain what you can see when you look at how asteroid orbit eccentricity and inclination vary with distance from the Sun.
Van Kane rounds up some of the latest NASA Discovery mission proposals aiming to explore our solar system's smallest bodies.
For Asteroid Day, Bruce Betts reviews 5 steps needed to prevent asteroid impacts, as well as how The Planetary Society is involved in those.
The six winners of the 2015 Shoemaker NEO Grants will use the grants to upgrade their observatories to improve their abilities to study potentially dangerous asteroids.
PROCYON (PRoximate Object Close flYby with Optical Navigation) is a microsatellite that launched on December 3 as a secondary payload with Hayabusa2. The mission has now selected their asteroid flyby target -- a binary asteroid named 2000 DP107 -- but is reporting a problem with their ion engines.
Thanks to a new focal reducer and re-aluminized mirror from a Shoemaker NEO grant, a 0.81-meter telescope in Italy is performing astrometric follow-up observations and physical studies of asteroids.
A huge amount of effort goes into deciding where to try to collect a sample on Bennu. There are roughly nine months to survey, map and model the asteroid to help make this decision.
Camera purchased with the support of a 2009 Shoemaker NEO Grant is now on a new telescope providing follow-up measurements for even fainter near-Earth objects.
Quan-Zhi Ye was an 18 year-old college student and the principal investigator of the Lulin Sky Survey when he won a 2007 Shoemaker NEO grant. He's now a Ph.D. candidate and provides an update on his work in meteor studies.
