Samantha Mathewson joined Space.com as an intern in the summer of 2016. She received a B.A. in Journalism and Environmental Science at the University of New Haven, in Connecticut. Previously, her work has been published in Nature World News.
Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesA 1.2% scale model of the Super Heavy rocket was put to the test in the transonic Unitary Plan Wind Tunnel at NASA's Ames Research Center in California's Silicon Valley.
Pressure-measuring sensors were affixed to the rocket model, allowing researchers to observe its stability and aerodynamic performance as it endured wind speeds ranging from Mach .7, or about 537 miles per hour, to Mach 1.4, or about 1,074 miles per hour. For reference, Mach 1 is the speed that sound waves travel, or 761 miles per hour, at sea level.
Super Heavy is equipped with four grid fins, which help stabilize and control the vehicle during re-entry. Several grid fin configurations were tested under varying aerodynamic conditions within the wind tunnel simulations, which took place over a two week time period earlier in the year. Four grid fins on the Super Heavy rocket help stabilize and control the rocket as it re-enters Earth's atmosphere after launching Starship to a lunar trajectory.
Wind tunnel testing at NASA's Ames Research Center helped engineers better understand the aerodynamic forces the SpaceX Super Heavy rocket, with its 33 Raptor engines, experiences during various stages of flight. As a result of the testing, engineers updated flight control algorithms and modified the exterior design of the rocket.
