SpaceX is rapidly manufacturing multiple Starship prototypes at the South Texas facility located in Brownsville’s Boca Chica beach. An orbital-class Starship will be equipped with six powerful Raptor engines. Raptors are fueled by cryogenic methane and liquid oxygen which is a unique fuel combination in the aerospace industry. Each Raptor is capable of producing over 200 tons, or 2MN (meganewtons), of thrust at full throttle. Three of Starship’s Raptors will be sea-level engines for atmospheric flight, and three vacuum-optimized Raptors for propulsion in space. Vacuum-optimized engines are more complex and different than sea-level engines; they’re specifically designed to have a higher performance in the vacuum of space. A visible difference between the two engines is that the bell nozzle is larger in the Raptor vacuum engine. Today, SpaceX shared a photograph showcasing the gigantic Raptor vacuum engine, pictured below.

Chief Engineer Elon Musk founded SpaceX with the goal to enable humans to live on Mars. The aerospace company is developing its next-generation launch vehicle in South Texas at Boca Chica Beach. According to SpaceX, Starship will be the most powerful rocket in the world; It will be a 120-meter-tall, two-stage launch vehicle consisting of a spacecraft capable of carrying one hundred passengers, and a Super Heavy booster used to propel the craft out of Earth’s atmosphere.

During the Humans To Mars teleconference that took place on Tuesday, Musk said Starship’s Super Heavy “booster prototype one” will initiate construction “this week.” SpaceX Boca Chica teams are building multiple Starship prototypes at the assembly facility, where gigantic vehicle assembly buildings are taking shape to accommodate the massive stainless-steel rocket booster. – “Making a prototype of something is, I think, relatively easy,” he said, “But building the production system so that you can build ultimately hundreds or thousands of Starships, that’s the hard part.”

Just playing around with the SpaceX footage from last nights SN6 hop. Enlarged and enhanced the video so we could zoom in on SN6 and the 2nd half of the video I slow it down X5.

“I was shocked at the huge increase in measured force,” Hal Fearn, close collaborator and physicist at California State University, Fullerton, told Wired.

Yet other researchers are still skeptical of the novel device.

“I’d say there’s between a 1-in-10 and 1-in-10,000,000 chance that it’s real, and probably toward the higher end of that spectrum,” Mike McDonald, an aerospace engineer at the Naval Research Laboratory in Maryland, told the magazine.

Over the last 12,000 years or so, human civilization has noticeably reshaped the Earth’s surface. But changes on our own planet will likely pale in comparison when humans settle on other celestial bodies. While many of the changes on Earth over the centuries have been related to food production, by way of agriculture, changes on other worlds will result, not only from the need for on-site production of food, but also for all other consumables, including air.

As vital as synthetic biology will be to the early piloted missions to Mars and voyages of exploration, it will become indispensable to establish a long-term human presence off-Earth, namely colonization. That’s because we’ve evolved over billions of years to thrive specifically in the environments provided by our home planet.

Our physiology is well-suited to Earth’s gravity and its oxygen-rich atmosphere. We also depend on Earth’s global magnetic field to shield us from intense space radiation in the form of charged particles. In comparison, Mars has only patches of localized magnetism, thought to be remnants of a global magnetic field in the distant past. Currently, the Red Planet has no global magnetic field that could trap particle radiation from interplanetary space. Also, the Martian atmosphere is so thin that any shielding against space radiation of any kind is minor compared with the protection that Earth’s atmosphere affords. At the Martian surface, atmospheric pressure never gets above 7 millibars. That’s like Earth at an altitude of about 27,000 m (89,000 ft), which is almost the edge of space. And while the moon’s proximity to Earth could make it a better location than Mars for the first off-world colony, the lunar radiation environment is similar to that of Mars.

Arianespace’s Vega rocket is scheduled to fly tonight (Sept. 2) for the first time in more than a year.

The four-stage Vega last launched in July 2019, and that mission did not go well. The 98-foot-tall (30 meters) rocket’s second-stage motor suffered an anomaly, resulting in the loss of the Vega and its payload, the United Arab Emirates’ Falcon Eye 1 Earth-observation satellite.

Tesla boss Elon Musk has been told by Germany’s economy minister that he can have whatever he needs for his new electric vehicle manufacturing plant in Berlin.

Musk and Germany economy minister Peter Altmaier had an hour long meeting in Berlin on Wednesday, according to a source familiar with the matter. “The main topics were Tesla’s billions of euros worth of investment in Germany,” the source said.

The duo, who first met six years ago, also spoke about Musk’s projects in areas like space flight and autonomous driving.

Demo-2 will be the first crewed mission in SpaceX’s history, as well as the first launch of NASA astronauts from the U.S. since 2011, sending NASA astronauts Bob Behnken and Doug Hurley to the International Space Station.
