NASA is zeroing in on Venus and asteroids [space.com] as potential targets for its next low-cost robotic exploration mission or missions, which will launch by the end of 2021.
The space agency has chosen five finalists for the next launch opportunity in its Discovery Program, which funds highly focused missions to destinations throughout the solar system. Two of the selected concepts would visit Venus, while asteroids are the objects of interest for the other three.
"The selected investigations have the potential to reveal much about the formation of our solar system and its dynamic processes," former astronaut John Grunsfeld, associate administrator for NASA's Science Mission Directorate in Washington, said in a statement Wednesday (Sept. 30).
