    ThTh8: It was an age of exploration, so unsurprising in that sense. I’m more taken by the error in the means of getting there — an assumption that there would be an energy source equivalent to wind that could be exploited. Fifty years after Apollo and the big hurdle to getting about in space is still getting out of Earth’s gravity well. In particular, getting enough reaction mass at least as far as LEO to get somewhere else in the kind of voyage times they thought about in 1610.Report

    This was fascinating to read. Thanks for writing! I’m a big fan of Hubble and I’m hoping that JW will get the opportunity to build on what Hubble has already taught us.Report
