How far offshore was splashdown? Mrs Tif was like "Shouldn't the Coast Guard be there or something?"

I don't think that far. Less than 50 miles offshore, and I think maybe around 20 miles.

I saw a blurb that apparently there were a ton more craft in the area that were observing the cordon the USCG had established, but a dozen or so vessels just says eff it and closed in. Asshats.

It took their spacecraft 37 minutes to get from New Zealand to Florida. To fly that commercially, it would take 28-34 hours with layovers.

Wouldn’t it be cool if airlines started using orbital flight paths? Or would your average airplane passenger not be able to handle the G-forces on either end? I mean, cost obviously would be a huge issue at first, but could come down over time.

I believe this is Elon's goal at some point. I'm sure they could come up with a way to slow the acceleration to a manageable rate, even if it took an hour to get up to speed. It would still save you multiple hours on a trip across the globe.

The Nazis tried to engineer a sub-orbital bomber to solve their problem of not being able to reach the American mainland.

Allen Steele wrote a fun alternate history book about this program making it much further along and a team in the U.S. formed to stop it. It's called V-S Day, recommend it.

Isn't sub-to-low orbital commercial flight the goal of Virgin Galactic?

Also, I just watched the ISS zip by overhead. (Well, technically it was overhead Arizona) That is so frickin' cool.

Yes, but I don't think they're planning any point-to-point flights. Basically just tourist hops and suborbital microgravity experiments, plus their smallsat launcher.

Virgin Galactic is working with Boom Technology on a new supersonic passenger aircraft. Boom has been developing a 50-passenger Mach 2.2 airliner for a number of years now. They supposedly just signed an agreement with Rolls for engine development. I remain circumspect on whether that project will ever fly. It would not have the range to do trans-Pacific flights and would need to refuel somewhere, but I think the biggest market would be transPac. I personally don't see spending the big bucks to knock a couple hours off a NY to London flight, but offer Tokyo to LAX or SFO in four hours instead of 11, and I think the price starts to get much more competitive/attractive.

I can see SSTs featuring in the inventories of state carriers to the Middle East, Australia, and southeast Asia, too.

SpaceX today conducted a successful 150-meter "hop" of the Starship SN5 prototype. It's flying slightly tilted because the Raptor engine is not centered. The operational Starship will have three Raptors in the center for landing. This prototype only has a single installed, so the thrust is off center.

So as I sit here and look up at the moon, I see a round planet roughly one foot away in the view screen. Mars?

Yup. Mars was tracking behind the moon last night.

Got a little bit of the milky way last night in the backyard after the game. I believe this is the northern cross section. Turned out better than I thought it would with all the light pollution. Pixel astrophotography mode is really amazing. Look up targets in star walk, point and shoot with tripod.

Not sure why I can't get the picture to post

The Air Force has announced the winners of its next five-year contracts to launch national security satellites for the U.S. military and intelligence agencies. Between 2022 and 2027, SpaceX and ULA will collectively will fly as many as 34 missions for the Department of Defense and the National Reconnaissance Office. It was a four-way competition between SpaceX (Falcon 9 and Falcon Heavy), ULA (Vulcan), Northrop Grumman (OmegA), and Blue Origin (New Glenn). Basically the Air Force ( I think soon to be the Space Force, once it's fully up and running) decided to stick with its two incumbent launch contractors. Blue Origin I'm sure will continue to develop the New Glenn vehicle on its own; Jeff Bezos has always had other plans. Whether Northrop Grumman continues to develop the proposed OmegA launcher is far less certain. My guess is that OmegA is DOA without government contracts.

This literally happens in Battlefield 4, as a set piece "Levelution." Players can destroy the cable stays and it pulls the support tower down through the dish. Pretty cool in game. No cool IRL :lol:
