SpaceX Starship Moves Closer to Launch With Successful Engine Test

According to CEO Elon Musk, the engine performed as expected during a 51-second test burn. Based on previous timelines, Musk suggests the Starship “Hopper” could be ready for its first untethered flight later this month. The Starship will eventually take over from the Falcon 9 and Falcon Heavy as SpaceX’s primary launch vehicle. That’s still off in the future, though. The company is still developing the technology that will let the Starship reach orbit, the moon, and even Mars. The current hurdle is the new Raptor engine that will power the Starship. SpaceX has yet to build a Raptor that can survive more than 100 seconds of cumulative test-fires, and Musk has insisted on pushing most hardware to the breaking point. It appears SpaceX is starting to learn a thing or two about the new engine designs, though. Past test engines have suffered from a nasty vibration resonance at 600Hz, which could shake the engine apart in flight. However, the sixth Raptor prototype (SN06) tested over the weekend at SpaceX’s facility showed no sign of vibration issues, according to Musk. The next-gen SpaceX vehicle will actually consist of two stages: the cargo/crew Starship and the Super Heavy launch stage. Super Heavy will have 31 Raptor engines, each one with more than twice the thrust of the Merlin 1D engines. The Starship will have six Raptor engines, three for use in the atmosphere and three for use in a vacuum. Exciting progress in Boca! Hopper almost ready to hover. Based on tonight’s test, looks like 600 Hz Raptor vibration problem is fixed.— Elon Musk (@elonmusk) July 7, 2019SpaceX is currently working on the “StarHopper,” which will demonstrate the craft’s ability to hover and land safely. Musk says the engine test did end with a safety abort, but that was expected. The team used the test to explore different fuel mixture ratios, causing the shutdown after 51 seconds. With the latest engine test finished, it could just be a matter of weeks before SpaceX fires up the prototype for an untethered flight. It previously flew a Starship Hopper on a tether in April. SpaceX has one Starship prototype under development in Texas and another in Florida. Once the Hopper phase is complete, SpaceX will scale the rocket up to prepare for spaceflight. The company hopes to begin commercial launches with the Starship as soon as 2021. Crewed flights, including the “Dear Moon” orbital mission, could follow soon after.Now read:SpaceX Fires Mars-Bound Raptor EngineElon Musk Explains Why the Starship Will Be Stainless SteelSpaceX Renames In-Development ‘BFR’ to ‘Starship’ Why The Hound May Have Been ‘GOT’s’ Most Important Character Bran’s Deleted ‘GoT’ Scene Would Have Changed Everything Facebook Twitter Linkedin Pinterest Google Plus Reddit Hacker News Flipboard Email Copy 0shares This site may earn affiliate commissions from the links on this page.
