    The first private mission outside of Earth’s orbit is closer than many of us think. (5) U.S. government officials are said to approve a mission by privately-held company, Moon Express, to travel outside of Earth’s orbit in late 2017. (6) Moon Express’s mission involves plans to land a suitcase-sized package of scientific equipment on the moon for ongoing exploration on commercial development. The decision involves months of lobbying on coordinated conversations between a number of federal agencies. Under international treaties, the U.S. is responsible for the cargo of both public and private and spacecraft. This makes commercial space travel a complex legal issue not just domestically, but abroad. (7) A Moon Express representative declined to comment on this story, but noted that the company is “very optimistic” about its proposal. Moon Express is not the only company thinking for the right to travel to outer space. Elon Musk’s SpaceX aims to send an unmanned aircraft to Mars by 2018.
