NASA to Resume Human Space Flight, Focus on Mars

NASA will partner with Boeing and SpaceX to build commercially owned and operated "space taxis" to fly astronauts to the International Space Station, ending U.S. dependence on Russia for rides, officials said on Tuesday (September 16). Both companies are already sending cargo resupply ships to the space agency but Tuesday's announcement marks the first time private sector companies will be entrusted with ferrying humans to the space station, NASA said.
