NASA Approves Two Bold New Asteroid Missions

NASA JPL January 04, 2017 NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed ... Read More »

Where the Ice is on Ceres – New Findings

NASA JPL December 15, 2016 At first glance, Ceres, the largest body in the main asteroid belt, may not look icy. Images from NASA’s Dawn spacecraft have revealed a dark, heavily cratered world whose brightest area is made of highly reflective salts — not ice. But newly published studies from Dawn scientists show two distinct lines of evidence for ice ... Read More »

Water is Everywhere in the Cosmos

NASA April 7, 2015 As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways. “NASA science activities have provided a wave of amazing findings related to ...

Dawn Spacecraft Begins Approach to Dwarf Planet Ceres

NASA JPL December 29, 2014 NASA’s Dawn spacecraft has entered an approach phase in which it will continue to close in on Ceres, a Texas-sized dwarf planet never before visited by a spacecraft. Dawn launched in 2007 and is scheduled to enter Ceres orbit in March 2015. Dawn recently emerged from solar conjunction, in which the spacecraft is on the ... Read More »

Learning to “Live Off the Land” in the Frontier of Space

NASA October 31, 2014 Safely sending human explorers to and from Mars will be the challenge of a generation. We don’t yet know what clues astronauts will uncover in the Martian soil or atmosphere that reveal new knowledge about our solar system, but one thing is certain, Mars contains critical resources that can sustain human presence. Harvesting those resources will ... Read More »

Curiosity Rover Finds Large Iron Meteorite on Mars

NASA July 15, 2014 This rock encountered by NASA’s Curiosity Mars rover is an iron meteorite called “Lebanon,” similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit and Opportunity.  Lebanon is about 2 yards or 2 meters wide (left to right, from this angle). The smaller piece in the foreground is ... Read More »

Boulder-sized Asteroid to be Captured, NASA Says

NASA June 19, 2014 NASA is on the hunt for an asteroid to capture with a robotic spacecraft, redirect to a stable orbit around the moon, and send astronauts to study in the 2020s — all on the agency’s human Path to Mars. Agency officials announced on Thursday recent progress to identify candidate asteroids for its Asteroid Redirect Mission (ARM), ... Read More »

Near-Earth Asteroid 2014 HQ124 – Mapped by Radar

NASA JPL June 12, 2014 NASA scientists using Earth-based radar have produced sharp views of a recently discovered asteroid as it slid silently past our planet. Captured on June 8, 2014, the new views of the object designated “2014 HQ124” are some of the most detailed radar images of a near-Earth asteroid ever obtained. An animation of the rotating asteroid ... Read More »

Mars Slammed by Big Meteor Impact

NASA JPL May 22, 2014 Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA’s Mars Reconnaissance Orbiter. The crater spans half the length of a football field and first appeared in March 2012. The impact that created it likely was preceded by an explosion in ... Read More »

Twenty-Six Asteroids Exploded Over Earth From 2000-2013

April 23, 2014 Between 2000 and 2013, a network of sensors that monitors Earth around the clock listening for the infrasound signature of nuclear detonations detected 26 explosions on Earth ranging in energy from 1-600 kilotons – all caused not by nuclear explosions, but rather by asteroid impacts. These findings were recently released from the Nuclear Test Ban Treaty Organization, which operates ... Read More »
