Early Thursday, founder and CEO Elon Musk tweeted some pictures from the SpaceX development facility in Boca Chica. They show the third spacecraft prototype from SpaceX called "SN3", which gets its crown in the vehicle assembly building of the site, which is basically a very high spacecraft garage.
You may recall that. That didn't seem to slow the company down much, as the tank for its successor SN2 passed its own pressure test less than two weeks later, on March 8th.
Now that SN3 is coming together, SpaceX will have a backup of its SN2 backup (which currently appears to be the primary test prototype).
According to Musk, the test model shown by all three prototypes should fly to a height of about 20 kilometers and land on Earth again. Ultimately, the goal is to create a next-generation spaceship that can transport people to the moon, Mars, and maybe even further.
