"The Falcon 9 lifted off at 6:53 p.m. EDT (2253 GMT) from historic Pad 39A at NASA's Kennedy Space Center in Florida. About 8.5 minutes later, the first stage came back to Earth for a pinpoint landing on the robotic SpaceX ship named "Of Course I Still Love You," which was stationed in the Atlantic Ocean. It was the second successful mission in three days for SpaceX. [The Rockets and Spaceships of SpaceX]
This was the booster's second successful landing; the first came on Feb. 19, when the rocket stage helped send SpaceX's Dragon cargo capsule on an uncrewed resupply run to the International Space Station (ISS) for NASA. (That February launch, by the way, was SpaceX's first from Pad 39A, which previously hosted liftoffs for NASA's Apollo and space shuttle programs.)" space.com
Re-usable boosters are now a proven commodity. SpaceX is IMO going to dominate the commercial space industry for a long time. I look forward to seeing the first flight test of their heavy booster.
I have been studying quantum mechanics lately. Any thoughts about that field? pl
""After visiting Hyperloop One’s test site in Nevada and meeting its leadership team this past summer, I am convinced this groundbreaking technology will change transportation as we know it and dramatically cut journey times," Virgin Group founder Richard Branson said in a press release.
Hyperloop One is headed by Shervin Pishevar, a Silicon Valley venture capitalist best known as an early investor in Uber. The Los Angeles-based startup is conducting feasibility studies in Dubai and Finland for the transit system. US cities like Denver and Nevada have also submitted proposals for the construction of a Hyperloop.
The Hyperloop is a nascent transportation system that works by shooting pods through a vacuumed-sealed tube at speeds that experts say could reach 700 mph. " BI
Branson visualizes tubes that can run underground, above ground or under water. Pods will carry passengers or cargo in these tubes at the speeds mentioned. He was interviewed on TV today and mentioned the prospect of cargo being unloaded offshore from ships tied up at artificial islands with the good then being loaded into pods for transport far inland bypassing existing harbors. The harbors can then be re-developed. pl
