Nothing to do with aviation, but I found this to be a very interesting story about what's happening at Kennedy Space Center in partnership with Florida Power and Light or as we used to refer to it back in the 1970's, Florida Flicker and Flash
With hundreds of thousands logging in all over the globe to watch, the 'much upgraded' Starship SN15 aced a test flight that had destroyed four prototypes before it.
On Wednesday, May 5, Starship serial number 15 (SN15) successfully completed SpaceX’s fifth high-altitude flight test of a Starship prototype from Starbase in Texas.
Similar to previous high-altitude flight tests of Starship, SN15 was powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN15 performed a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.
The Starship prototype descended under active aerodynamic control, accomplished by independent movement of two forward and two aft flaps on the vehicle. All four flaps were actuated by an onboard flight computer to control Starship’s attitude during flight and enabled precise landing at the intended location. SN15’s Raptor engines reignited as the vehicle performed the landing flip maneuver immediately before touching down for a nominal landing on the pad.
While a small fire (probably methane-fed) was evident for several minutes after the landing, it was eventually extinguished without visible damage.
SpaceX notes that, "These test flights of Starship are all about improving our understanding and development of a fully reusable transportation system designed to carry both crew and cargo on long-duration interplanetary flights, and help humanity return to the Moon, and travel to Mars and beyond."
SpaceX's Starlink megaconstellation is designed to provide global broadband coverage for high-speed internet access, particularly for people in rural and remote areas. Each of the flat-panel Starlink satellites weighs roughly a quarter-ton and are built in-house at a SpaceX facility in Redmond, Washington. (The company also manufactures its own own user terminals and ground stations.) While SpaceX expects its initial set of Starlink satellites to be 1,440 strong, the company has plans to launch thousands more. Company founder and CEO Elon Musk has said SpaceX needs between 500 and 800 satellites in orbit before service can begin to roll out. SpaceX is inching closer and closer to that goal, as it has delivered nearly 800 into orbit so far.
The Federal Communications Commission has granted SpaceX permission to launch as many as 12,000 of the flat-panel broadband satellites, but SpaceX may not stop there. The company has indicated it will see approval to launch as many as 30,000 of its internet-beaming satellites to beam down high-speed, low-latency Internet signals.
SpaceX plans to get even more ambitious with its pinpoint rocket landings.
Elon Musk's company routinely recovers and reuses the first stages of its Falcon 9 and Falcon Heavy rockets, bringing the boosters down for soft vertical landingsabout 9 minutes after liftoff on ground near the launch pad or on autonomous "drone ships" in the ocean.
These touchdowns are impressively precise. But SpaceX aims to achieve something truly mind-blowing with Starship, the next-generation system the company is developing to take people and payloads to the moon, Mars and other distant destinations.
