UPDATE: SpaceX’s latest prototype launched successfully, but like its previous test flight, the rocket exploded on impact during an attempted landing Read more here

SpaceX is preparing to launch the latest prototype of its next-generation Starship rocket in the system’s second high-altitude test on Tuesday

The Starship prototype Serial Number 9 or SN9 flies up to 10 kilometers, or about 32800 feet altitude, the flight will be similar to the SpaceX conducted in December, when the prototype SN8 was launched on the tallest and longest flight ever.The SN8 flight met several development goals, including testing the system’s aerodynamics and performing a flip to suit itself to orientate the landing However, the prototype exploded on impact because the missile could not slow down enough

SN9 is made of stainless steel, with the prototypes representing the early versions of the rocket that CEO Elon Musk unveiled last year The company is developing Starship with the aim of bringing cargo and up to 100 people on missions to the moon and Mars at the same time / p>

As with SN8, the goal of the SN9 flight is not necessarily to reach maximum altitude, but rather to test several key parts of the starship system.The Starship prototype is about 150 feet tall, or about the size of a 15-story building and is powered by three Raptor rocket engines. SpaceX fires all three engines to take off, then shuts them down one after the other as they approach the intended flight altitude

SN9’s attempt to launch was delayed by about a week as SpaceX worked to get permission from the Federal Aviation Administration to launch its SN8 flight violated the company’s existing Starship license, The Verge First and the FAA reported later confirmed that the federal aerospace agency had denied a SpaceX exemption request to exceed the maximum public risk allowed by federal safety regulations statement

SpaceX had to investigate its non-compliance and force Musk’s company to suspend launch until the investigation was completed and the FAA signed out

“The FAA determined late Monday (February) 1) that SpaceX complies with all safety and related federal regulations and is authorized to conduct SN9 operations under its launch license,” said the FAA

The most important tests for the SN9 flight include turning off the engines one by one, transferring the propellant from the main tanks to the header, turning it over for the “belly flop” re-entry maneuver, and controlling the descent through the air with the four flaps on the rocket

SpaceX stressed that “the dynamic development test schedule” may result in the attempt to launch being delayed, as was the case with previous Starship launches
