This week's Question: Last week, NASA's 30,000-pound Orion capsule landed in the Pacific Ocean after going further than any spacecraft built for humans had reached in more than 40 years. Without astronauts aboard, Orion circled Earth for two orbits, eventually reaching an altitude of 3,600 miles so it could achieve a high re-entry speed, one similar to a beyond-Earth-orbit flight. The mission is a step toward eventually bringing astronauts to deep space. NASA says astronauts could reach Mars sometime in the 2030s. What do you think? Will astronauts reach Mars by 2030?
