That vehicle was originally supposed to perform a test flight to an altitude of 65,000 feet (20 kilometers), but SpaceX said they had changed those plans and repurposed the Starship Mk1 to a ground test unit before the Nov. 20 mishap.<\/p>\n<p>A modified Starship prototype named SN1 collapsed during a Feb. 28 pressure test. Musk said engineers believed that failure was with a \u201cthrust puck\u201d at the bottom of the vehicle that transfers loads from the vehicle\u2019s Raptor engines.<\/p>\n<p>SpaceX stripped down the next Starship prototype, named SN2, to test the weld connecting the thrust puck to the vehicle. That testing was successful.<\/p>\n<p>Like SN1, the SN3 prototype was built without aerodynamic fins or a nose cone, which would be included in a full-size flight vehicle.<\/p>\n<p>Construction of the next Starship vehicle, named SN4, has already started in South Texas. The work is continuing amid the coronavirus pandemic, and many aerospace companies like SpaceX are continuing their work under exemptions to local and state stay-at-home orders.<\/p>\n<p>Aerospace parts are considered part of the nation\u2019s critical manufacturing sector, and SpaceX is considered part of the U.S. military\u2019s industrial base. The Starship could eventually launch national security payloads.<\/p>\n<p>SpaceX is also planning a Starship production facility in Los Angeles, and could launch future Starships from the Kennedy Space Center in Florida. For now, production and testing is centered in South Texas.<\/p>\n<p>The company recently published its first Starship payload user\u2019s guide.<\/p>\n<p>In the user\u2019s guide, SpaceX officials wrote that the Starship and Super Heavy could deliver more than 100 metric tons to low Earth orbit, and 21 metric tons (more than 46,000 pounds) to geostationary transfer orbit, the drop-off point for many commercial and military communications satellites.<\/p>\n<p>With in-orbit refueling, a capability still in the nascent stages of development, the Starship could deliver more than 100 metric tons of payload to the surface of the moon or Mars, according to SpaceX.<\/p>\n<p>A crew-capable configuration of the Starship could ferry up to 100 people from Earth to low Earth orbit, the moon, or Mars, SpaceX says.<\/p>\n<p>\u201cThe crew configuration of Starship includes private cabins, large common areas, centralized storage, solar storm shelters and a viewing gallery,\u201d SpaceX wrote in the Starship user\u2019s guide.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\ufeff A prototype for SpaceX\u2019s Starship space vehicle collapsed during pressure testing early Friday at the company\u2019s facility in South Texas \u2014 the program\u2019s third failure during such testing since November \u2014 but assembly of a new version is already underway.
