Getting to space is hard, and SpaceX is working through some kinks early in the process of developing its next-generation .
Video from sources with a view of the company's Boca Chica, Texas, development facility showed Starship prototype "SN1" apparently exploding during a pressure test Friday.
NASASpaceflight reported that the partial rocket failed during a cryogenic pressure test after one of its tanks filled with liquid nitrogen.
An earlier, more basic prototype dubbedat Boca Chica last year.
This latest anomaly -- as explosions tend to be called in the space business -- appears to be doing little to set back Starship's development. Elon Musk showed off the company'sat Boca Chica last month, and prototype SN2 continued to come together on one side of the site this weekend, even as the remains of SN1 were being cleaned up nearby.
SpaceX didn't immediately return a request for comment.
The company is still working toward the next test flight of Starship in the coming months, which will aim to send it to serious altitude for the first time, up to about 12.4 miles (20 km).
