SpaceX's first launch attempt on Wednesday, around 3 pm CT, was aborted at the last tenth of a second. SpaceX CEO Elon Musk said in a tweet that the abort was triggered by pre-set standards around the rocket's thrust, which Musk described as "slightly conservative." He added that the company would increase the rocket's thrust limit, giving the rocket more wiggle room for getting a go-ahead for liftoff. The company then recycled the SN10's fuel ahead of the second, successful attempt.

Insprucker, who hosted the company's webcast of the launch on Wednesday, said that the primary goal of the test was to gather data on how the vehicle's flaps would control the Starship prototype as it plummets back to the Earth.

Perfecting the belly-flop landing maneuver is essential to "enable a fully reusable transportation system designed to carry both crew and cargo on long-duration, interplanetary flights and help humanity return to the Moon, and travel to Mars and beyond," according to the company's website.

SpaceX intends to use Starship for a variety of purposes, including shuttling paying customers between cities at breakneck speeds, potentially aiding NASA's Moon landing efforts, and, eventually, launching cargo and human missions to Mars.

Starship is still in the early stages of development. A full-scale prototype has yet to be constructed. SpaceX has not yet begun publicly testing Super Heavy, a gargantuan rocket booster that will be needed to propel the Starship to Earth's orbit or beyond.

Musk said during a recent interview with podcast host Joe Rogan that he expects Starship will be conducting regular flights by 2023, and he hopes the vehicle will reach orbit by the end of this year. It's not clear if SpaceX will hit that deadline. The aerospace industry, and Musk in particular, is notorious for announcing projects that take far longer — and tally much higher expenses — than first anticipated.
