SpaceX, the private space technology company owned by Elon Musk, is asking federal authorities to approve a new round of tests for a prototype reusable rocket, but some of them may never make it back to the surface intact and will crash in the ocean.

SpaceX CEO Elon Musk described the explosion of the company’s Starship spacecraft during its seventh flight test Thursday as “barely a bump in the road,” underlining the momentum behind the commercial space giant.
