Precisely! We have the technology, but I think people do not realize we have the technology. They think to tackle climate change, we have to reduce our ambitions for the future (which isn't true) or that human life depends essentially on fossil fuels. There are no fossil fuels in space. That is why space travel and tackling climate change go hand in hand: space travel is tangible evidence of civilizational capacity, that we can do ambitious things even harder than fighting climate change (and we don't even have to spend THAT much to do those things) and we don't need fossil fuels to do it. It also provides an essential kind of perspective that I really think is essential to broad-based environmental consciousness.
