“Hundreds of design improvements” in prototype contributed to test’s successful completion.
There has been much good news recently related to the American space program. First, I reviewed the successful tests run on Mars by the Perseverance rover’s Ingenuity helicopter and oxygen-generation unit (MOXIE).
Now, after several spectacular failures, the SpaceX Starship SN15 rocket had a completely successful test flight…and landing.
Elon Musk’s SpaceX launched and then landed the latest prototype of its Starship rocket on Wednesday, in the fifth high-altitude test flight of the system.
Starship prototype rocket Serial Number 15, or SN15, flew as high as 10 kilometers, or about 33,000 feet.
“Starship landing nominal!” Musk tweeted after the landing. Nominal is a space industry term used to refer to when things go according to plan.
SN15 marked the first Starship prototype that was not destroyed after a high-altitude test flight. While a small fire broke out at the base of the rocket after the landing, the blaze appeared contained a few minutes later.
Starship landing nominal!

The vehicle is a prototype for the spacecraft that is being designed for potential human-crewed missions to Mars. SpaceX launched SN15 around 6:15 pm ET from its testing facility in Boca Chica, Texas.
SN15 ignited its three massive Raptor Engines that released out streams of white smoke from the base before fire blew out to shoot the rocket into the air.
The prototype climbed through the sky until it reached six miles, where it hovered for a moment and then it perform the infamous sideways flip, dubbed a ‘belly flop’ maneuver by CEO Elon Musk.
After hitting the six-mile mark, the rocket hovered in place for a few seconds using just a single rocket and then performed a controlled aerodynamic descent.
This mimics the technique Starship will use when returning through Earth’s atmosphere from space – presenting the ‘belly’ as it enters the atmosphere reduces the speed of descent as it approaches the ground.
SN15’s Raptor engines reignited as the vehicle attempted a landing flip maneuver immediately before touching down on the landing pad adjacent to the launch mount, it shut down the Raptor Engines and stood tall on the pad.
Musk indicated that the SN15 prototype included “hundreds of design improvements” in structures, engines, avionics, and software that contributed to the successful test.
SpaceX said in a statement Wednesday that the upgrades “will allow more speed and efficiency throughout production and flight.” The changes include “a new enhanced avionics suite, updated propellant architecture in the aft skirt, and a new Raptor engine design and configuration,” SpaceX said.
SpaceX is developing the Starship spacecraft and its huge booster rocket, named the Super Heavy, as a fully reusable launch and space transportation system capable of ferrying more than 100 metric tons of cargo into low Earth orbit, more than any other rocket in the world.
With in-space refueling, the Starship could eventually carry people and heavy supply loads to the Moon and Mars.
Now to get humans ready for such a mission, which may be a more complicated matter.
Astronauts’ faecal matter has revealed startling changes to how the human body is affected in isolation, such as during a crewed mission to Mars.
The Mars500 experiment put crew members from Russia, Europe, and China in a completely sealed habitat between June 2010 and November 2011. Researchers have looked again at the data from that work – and discovered new information that could help future trips.
The aim of this was to test the physiological and psychological effects on human health, with all six participants showing major changes in body mass, muscle strength, and gut microbiota.
One of these symptoms was major disruption to glucose metabolism, which is often seen after space flight. Glucose is a subcategory of carbohydrates, found in bread, fruits, vegetables, and dairy products, and is one of the body’s preferred source of fuel.
Researchers discovered that there was a loss of beneficial gut bacteria that would usually break down starch, prevent intestine inflammation, and absorb nutrients. They also discovered it increased gut bacteria that has only recently been discovered in humans – the effects of which are not yet fully understood.
Meanwhile, let’s enjoy the rebirth of a serious successful American space program.
🚨THE STARSHIP HAS LANDED!
Mars is a little bit closer today, congratulation to SpaceX you are inspiring millions of people around the world.
