NASA announced two new asteroid missions today named Lucy and Psyche that will fill important gaps in our understanding of how the solar system was formed. Here are eight things to know about the two missions.
NASA announced the first-round selections for its next Discovery mission today. A total of five planetary mission concepts -- three targeted at asteroids, two at Venus -- will move to the next stage of the competition.
With the release of the official Announcement of Opportunity (AO) early in November, NASA has officially begun the competition to select its next low cost ($450M) Discovery program planetary mission. Because planetary scientists are free to propose missions to any destination in the solar system other than the sun and Earth, these competitions bring out the creativity in the planetary science program.
