Starship fires (virtually) all her engines
SpaceX’s Starship carried out a profitable full-duration static check hearth at 3:13 p.m. CST right this moment (21:13 UTC Thursday, February 9, 2023) at Starbase in Boca Chica, Texas. The check – by which the (first stage) engines are ignited (“fired”), however the automobile doesn’t launch (stays “static”) – concerned the Starship Tremendous Heavy Booster 7. SpaceX is growing Starship as a fully-reusable tremendous heavy-lift launch automobile. It’ll be integral to missions to the moon and Mars. Starship stands 390 toes tall (120 meters tall). It has greater than twice the thrust of the Saturn V rockets that carried the primary astronauts to the moon. It’s designed to be the tallest and strongest launch automobile ever constructed, and the primary able to total reusability. Woo-hoo!

SpaceX introduced the check’s end result by way of Twitter:
First static hearth try of 33 Raptor engines on Booster 7 https://t.co/3haor6owfa

Based on SpaceX CEO Elon Musk, talking by way of Twitter, flight controllers disabled one of many craft’s 33 Raptor engines previous to the profitable check. One other Raptor lower itself off mid-burn:
Crew turned off 1 engine simply earlier than begin & 1 stopped itself, so 31 engines fired general.
However nonetheless sufficient engines to succeed in orbit! https://t.co/QYx3oVM4Gw

Firing check was a record-setter
Some back-of-a-napkin math had New Zealand-based spaceflight reporter Marcus House questioning if right this moment’s check hearth set a report for essentially the most thrust ever generated by a booster.
Was this essentially the most thrust in historical past for any rocket? That may be fairly the headline. If these engines have been throttled up previous ~65% for the 31, (assuming 230t full thrust per engine), then it ought to have beat the N1 I believe.

Whereas it isn’t sure but that Starship outpowered the ill-fated Soviet N1 moonship, one other of that craft’s information was surpassed. Right this moment’s check concerned 31 engines firing concurrently, yet another than the 30 engines on the N1 that would have flown cosmonauts to the moon.
Tearing up Texas!
As previously reported by EarthSky.org, Starship has already cleared all the opposite hurdles on the trail to an orbital check flight. The Federal Aviation Administration should grant a license to fly earlier than the complete Starship stack – the booster examined right this moment topped by a Starship cargo craft – can elevate off on its maiden voyage.
A part of the FAA’s concern entails the impression of testing at Starbase on the native ecology. The location is adjoining to the Las Palomas Wildlife Management Area. Video of right this moment’s check supplied by NASASpaceFlight.com exhibits flocks of birds startling into flight because the booster fires. The ability of the 31 engines tore free chunks of the Texas panorama that may be heard falling again to Earth close to distant cameras.
