If Musks schedule is accurate, Starship SN8 might be totally outfitted with a nosecone and flaps and prepared to roll to the launch pad for screening as early as next week. Prior to the first 20 km (~ 12.5 mi) hop and skydiver-style landing effort, Musk says that SpaceX will put SN8 through a static fire test (perhaps the first with three Raptor engines). The rocket will be thoroughly examined before carrying out a 2nd fixed fire test if it makes it through. If that second test is effective, SN8 will finally be cleared for Starships very first high-altitude launch and landing attempt.
Unmentioned, Starship test tank SN7.1 might be hours away from kicking off a cryogenic tension test crucial to the future of Starship SN8 and several of its successors. In that occasion, Starship SN8 would likely serve as a test tank instead of ending up being the very first high-altitude flight post. Unlike Starship Mk1, which was temporarily equipped with flaps and a nosecone more as a full-size mockup than a flight post, there is a very real chance that Starship SN8 will really perform a flight test with its nose and flaps set up.
Unlike the Space Shuttle or other proposed spaceplanes, SpaceXs present Starship style incorporates flaps to make sure aerodynamic stability while free-falling belly-first through the atmosphere, similar to a skydiver using limbs to steer through the air.
On August 4th, SpaceX effectively hopped a full-scale Starship prototype (identification number 5 or SN5) for the first time, reaching the same 150m (~ 500 feet) apogee Starhopper soared to just shy of one year prior. On September 3rd, just 30 days later on, Starship SN6– a totally different full-blown prototype with a various Raptor engine– finished an identical 150m hop, though Musk kept in mind that it was “a much smoother & & much faster operation.” The entire function of performing the exact same hop with two nearly similar ships was to establish and enhance the nascent process of Starship flight testing.
Musks indicator that “numerous” short hops would be carried out strongly suggested that SN5, SN6, or both ships would fly a second time. Now, however, Musk– supported by a NASASpaceflight.com report– appears to be suggesting that the very first high-altitude Starship (SN8) is up next on the docket.
CEO Elon Musk says that SpaceXs very first high-altitude Starship prototype– developed entirely out of a brand-new steel alloy– will be completely assembled “about a week” from now.

New and enhanced Starship flaps very first gotten here in Texas all the method back in June and were recently signed up with by numerous more to complete two full sets of four. (NASASpaceflight– bocachicagal)Meanwhile, SpaceX is working all the time to equip Starship SN8 and prepare the ship for the installation of a nosecone section and four aerodynamic control surfaces called flaps. Unlike Starship Mk1, which was briefly outfitted with flaps and a nosecone more as a full-size mockup than a flight article, there is a very real chance that Starship SN8 will actually perform a flight test with its nose and flaps installed.
Specialists prepare to install functional flaps on a Starship prototype for the first time ever. (NASASpaceflight– bocachicagal)According to NASASpaceflight, SpaceX is now working towards the first high-altitude launch of Starship SN8 as early as October. Prior to that ambitious test flight, however, numerous important turning points stand in the way. Unmentioned, Starship test tank SN7.1 might be hours far from kicking off a cryogenic tension test vital to the future of Starship SN8 and numerous of its successors. Built out of a steel alloy that is somewhat more ductile and pliable at cryogenic temperature levels, a successful SN7.1 tension test would open the door for SN8– the first major model constructed out of the exact same brand-new alloy– to start evaluating instantly thereafter.
As with all tests, however, failure is a strong possibility and would likely need more analysis of the brand-new steel alloy and some level of redesign for numerous affected Starship parts. In that event, Starship SN8 would likely serve as a test tank instead of ending up being the first high-altitude flight article. SN7.1s trials are set to begin no earlier than (NET) 9pm CDT (UTC-5) on September 14th and could continue all the method approximately September 23rd.
If that second test is effective, SN8 will lastly be cleared for Starships first high-altitude launch and landing effort.
The “enjoyable” thing is if it introduces, gets a few of the goals done and after that has a problem … its still an action forward, and you have SN10, sn11 and sn9 waiting in the wings.
, if SLS has a bad day during the Green Run … Such a distinct approach to testing..– Chris B– NSF (@NASASpaceflight) September 12, 2020
