Lost in space? Nasa chief urges US to work with China on future manned space missions or risk getting left behind

The United States should include China in its human space projects or face being left out of new ventures to send people beyond the International Space Station, Nasa chief Charles Bolden said.
The US space agency has been banned by Congress since 2011 from collaborating with China due to human rights issues and national security concerns.
China is not a member of the 15-nation partnership that owns and operates the station, a permanently staffed research laboratory that flies about 400 km above Earth, but Bolden says working with China will be necessary in the future.
