NASA has drawn up its Constellation mission manifest, which sets out the dates and full mission baselines for the test flights, International Space Station (ISS) manned and unmanned missions, plus the first flights to the moon. The highlight of the manifest is Orion 13 – a 21 day mission, launching in December 2019 – which will see three members of a four man crew set foot on the lunar surface for the first time since 1972.
