Virgin Galactic today revealed a new partnership with NASA, in pursuit of the goal of developing a high-speed vehicle for point-to-point travel across Earth. NASA has been pursuing development of high-mach air travel itself, with the development of its Supersonic X-59 low-boon supersonic test plane built by Lockheed Martin, but this new partnership agreement with Virgin Galactic and its subsidiary The Spaceship Company specifically seeks to figure out a sustainable way to apply high-speed transportation technologies to civil and commercial aviation. Virgin Galactic thinks it will be able to get a head start on this project specifically because of the work it has done to date on developing, engineering and flight-testing its existent vehicles, which include the WhiteKnightTwo carrier aircraft, and the SpaceShipTwo winged spacecraft that launches from the carrier to reach the edge of space. The design of the company’s system uses traditional runways for take-off and landing, while the rocket-propelled SpaceShipTwo skims the outer edge of Earth’s atmosphere at the boundary of space to provide its commercial tourist passengers with a trip that includes stunning views and a few minutes of weightlessness. In fact, Virgin Galactic’s technology does seem like a good fit for point-to-point high-speed travel. Perhaps best popularized by SpaceX and one of their many ambitious plans for their forthcoming Starship, point-to-point envisions traveling between two places on Earth at very high speeds either extremely high up in the atmosphere (much higher than current commercial planes go) or even potentially through space. The advantages of doing this are that you can go much faster as the atmosphere thins and friction and air resistance lower. The International Space Station, for instance, performs a full orbit around Earth once every 90 minutes. A trip from NYC to Shanghai using Starship would take just 40 minutes, SpaceX has said, rather than the 16 hours it takes today. Virgin Galactic and NASA aren’t yet near the stage where they’re talking about trip times, but for comparison’s sake, consider that SpaceShipTwo travels at a top speed of around 4,000 km/h (nearly 2,500 mph), while a Boeing 747 maxes out at about 988 km/h (just under 615 mph). The new partnership between Virgin Galactic and NASA was formed under a Space Act Agreement, which is a type of agreement that NASA uses to work with organizations it deems able to help it fulfill its various goals, missions and program directives. It’s early yet to imagine what this will look like exactly, but Virgin Galactic says in a press release that it will be “seeking to develop a vehicle for the next-generation of safe and efficient high speed air travel, with a focus on customer experience and environmental responsibility,” and that it will be doing so in cooperation with its “industry partners.” Source | ||

"a focus on customer experience and environmental responsibility" sounds highly questionable. How is this supposed to be less environmentally impactful than normal air travel, which is already absurdly unfriendly to the climate? Especially considering that they will probably transport a small amount of very rich people who can afford such a trip? To me, this sounds like next gen luxury travel. Highly wasteful, but the superrich can pay for it, and burn more fuel to produce more CO2 just for a quick shopping trip to Paris. | ||

Federal Communications Commission Ajit Pai has recast his media team with the departure of press secretary Tina Pelkey after a nearly three-year run. She is joining Blue Origin, the aerospace enterprise owned by Amazon CEO Jeff Bezos. Pelkey will be senior manager, government affairs communication. Source NASA astronauts Bob Behnken and Doug Hurley completed their final training sessions in Houston this week before their scheduled May 27 liftoff on a SpaceX Dragon spacecraft from the Kennedy Space Center, the first launch of humans from the Florida spaceport since 2011. The two veteran space fliers participated in their final full-up launch simulation Monday, strapping into a Dragon simulator at the Johnson Space Center in Houston and tying in with SpaceX and NASA teams at the Kennedy Space Center in Florida and at SpaceX headquarters in Hawthorne, California. Behnken tweeted Thursday that the crew’s formal training activities were complete. The astronauts were expected to have a few days of off-duty time before preparing to travel from their home base in Houston to the Kennedy Space Center on May 20. Source It seems with the continued success of the SN4 a backlog has started at Boca Chica. | ||

Safe bet, hope not, that launch will be scrubbed due to clouds. Both parties want everything to be perfect. ![]() | ||

I wonder if there is any video to be found of the VO assplosion. Would love to see it. | ||

Problems: Granularity. There is a lot of stuff in the universe, and the further away it is, the less easy the details are to see. For example, in our solar system, there are a bunch of asteroid belts. Do we need to chart every single asteroid? Or is it fine to just write "asteroid belt" onto our map? This gets harder the further out we go. Do we need to chart every single planet of a star system, or is it okay to just write "star system"? Do we need to chart every star system in a galaxy far, far away, or is it okay to just write "galaxy"? How small is the smallest thing that needs to be put into our map? What can be allowed to fall through the cracks? Time. We see stuff with a lightspeed time lag. In our solar system, that is not a big problem, and leads to our information maybe being a few hours old. But it gets worse in other star systems or galaxies. One would expect a map to display how stuff is right now, or at least how it was at the same point in time. But for some things, we can only see how they were a few billion years ago. Stuff expands all the time, so some parts of the universe are impossible to ever observe. Even worse, due to special relativity it is actually impossible to establish a coherent "same time" framework. Related to the last, there is Change. Stuff changes, and systems of many bodies can behave very unpredictable. Also, Supernovas are mostly unpredictable, so we cannot even see if that star which we only see how it looked like 50 million years ago still exists. Or complex interactions between lots of stuff in an asteroid belt. The universe might be infinite. We are not sure. That alone would make a "map of the universe" impossible. Without superluminal speed (which is very SciFi), there is no way to get anything resembling a "map of the universe", and even with superluminal speed, it is questionable. | ||
