Curiosity to Get Company, but Will Have to Wait a While

摘要

Although NASA's plan to return to Mars with robots was given up for dead not long ago, the aerospace agency has now announced that its rover Curiosity will get some company on the Red Planet starting in 2020. NASA plans to launch a new rover based on the technology in the Mars Science Laboratory mission, which carried the Curiosity rover to the planet's surface this summer. That will help keep costs down, NASA says.
