"NASA Scraps Launch of Two Completed Asteroid Probes"
NASA has announced that two small spacecraft, part of the Janus mission to study unexplored asteroids, will remain locked inside a Lockheed Martin factory in Colorado. The delay in the launch of NASA's larger Psyche spacecraft, due to software testing issues, led to the cancellation of the Janus mission. The Janus spacecraft were designed to study binary asteroids closer to Earth than the Psyche asteroid. The asteroids targeted by Janus have since moved too far from the Sun for the spacecraft's solar arrays to generate sufficient power. The decision was driven by budget constraints and limited resources at NASA.
