What’s old is new again – more on refueling in space

NASA’s human spaceflight strategy, sustainability and growth

The reward is everyone's ability to go further. It’s not every day you are told your choices are not yours alone. Last year’s 2020 Space Council report did just this. NASA’s deep space exploration and the US commercial space sector are linked. The report was clear, a commercial space economy is “necessary” for NASA’s deep … Continue reading NASA’s human spaceflight strategy, sustainability and growth
