She actually is promising if she can handle the schooling. All the space camps is an accomplishment for a teenager. If she can stay motivated then I could see her succeeding. Pretty shitty of the media to spin it that way however because now she will get a bunch of hate for nothing.

>It is often said that top scientists can visualize concepts to an extreme degree when they're thinking about a problem.

Sir Francis Galton found the exact opposite correlation in his research http://psychclassics.yorku.ca/Galton/imagery.htm

>Here then are two rather notable results: the one is the proved facility of obtaining statistical insight into the processes of other [p. 304] persons' minds; and the other is that scientific men as a class have feeble powers of visual representation. There is no doubt whatever on the latter point, however it may be accounted for. My own conclusion is, that an over-readiness to perceive clear mental pictures is antagonistic to the acquirement of habits of highly generalised and abstract thought, and that if the faculty of producing them was ever possessed by men who think hard, it is very apt to be lost by disuse. The highest minds are probably those in which it is not lost, but subordinated, and is ready for use on suitable occasions. I am however bound to say, that the missing faculty seems to be replaced so serviceably by other modes of conception, chiefly I believe connected with the motor sense, that men who declare themselves entirely deficient in the power of seeing mental pictures can nevertheless give life-like descriptions of what they have seen, and can otherwise express themselves as if they were gifted with a vivid visual imagination. They can also become painters of the rank of Royal Academicians.

Glass in space is hard. It's not that easy in rocketry.

Here's to you Bob and Doug.

Skimming through the FFA license, Starship could potentially attempt a hop from Thursday since they have to give 3 business days to declare nominal thrust profile and how much propellant is being loaded.

DM-1 already happened, anon. It was the uncrewed test mission with the high tech plush gravity sensor.

>Now more than 12 hours after Starship SN4 fired up its new Raptor engine, the ~30m (~100 ft) tall, 9m (~30 ft) wide prototype is apparently trapped with one or both of its propellant tanks still partially filled with liquid (or gaseous) methane and/or oxygen. An initial road closure scheduled from noon to 6pm local quickly came and went and SpaceX and Cameron County Texas have since modified the paperwork, extending the closure a full 24 hours. In other words, SpaceX has reason to believe that Starship SN4 may continue to be unsafe (i.e. pressurized) as many as ~30 hours after it technically completed its third static fire test

My bet is it will never be allowed to hop now and they will move onto SN5 for the 150m hop.

Dare I say... BASED.

>An atmospheric test of the Dragon 2 abort system at Max Q. The spacecraft will deploy parachutes and splashdown in the ocean. The test was planned to be performed on the SpX-DM1 capsule before it exploded during a SuperDraco engine test on April 20, 2019. The abort test will now use the capsule originally intended for the first crewed flight.
>February 2020 Dragon 2 will carry its first crew, NASA astronauts Douglas Hurley and Bob Behnken, on a 14-day test mission to the ISS. This flight will use a new booster.
Can they turn the Dragon round in a month? Would have thought it would take longer since knowing NASA they will probably demand a bunch of after tests...

Don't worry guys i-it happened on purpose

Why do we use convolution when applying a signal to an impulse response. Wouldn't it be much more logical to use composition?
