(Star those things about programmers)
Yesterday's tweet introduced the technology stack of SpaceX software engineers .
Today, I recommend a video released by SpaceX officially in September 2017, which summarizes the failure cases of rocket recovery. The background music is authentic and naughty .
video
Remind everyone to read the accompanying text of each failed case. It matches the BGM very well and is quite joyful.
such as:
Rocket is fine? it's just a scratch (???? Is it okay? Just scratched)
well, technically, it did land……just on in one piece (well, technically, it did land on the ground, but not a whole piece) (this is because there is not enough fuel, it was almost a little bit, and then fell Fell exploded)
Look, it's not an explosion (note, this this is not an explosion)
It's a rapid unscheduled dissasembly (this is a rapid unscheduled dissasembly)entropy…is such a lonely word (entropy is a lonely word)
the course of true love never did run smooth
The last two of the video were successfully landed and recovered on land and sea respectively!
SpaceX's unmanned automatic recovery ships, their names are also very happy:
> Just Read The Instructions (Just Read The Instructions)
> Of Course I Still Love You (Of course I still love you)
> A Shortfall of Gravitas (Lack of Gravitas) (this one has not yet been built)
Tips:
Grasshopper, a small recyclable rocket developed by SpaceX.
> 2011 announced the start of development;
> First test on September 21, 2012, lifted 6 feet (1.8 meters), hovering for 1.3 seconds;
> Grasshopper and Falcon 9 both use Merlin rocket engines;
> Grasshopper's main Purpose: Test the recovery mode of Falcon 9 + collect data through flight experiments.

@意气风发的鼠子: Just dare to broadcast it. The last one was perfect.
@JIMMYs Animation Theater: This may be the most expensive video you have ever seen
