Being forced into isolation and confinement creates a number of potentially stressful demands. However, we might be able to learn a thing or two about coping with these demands, from people who choose a life in such settings.
And ArsTechnica seems to be totally missing the point as “delaying” Starship for SOUND AND PRACTICAL SAFETY AND ENVIRONMENTAL QUESTIONS is not ‘delaying’ progress and one needs to simply ask why SpaceX “engineers” can’t up their game enough to actually answer or address those legitimate questions? The answer is rather simple, they probably CAN but the person “in charge” has no with to, incentive to, or will to do so because he sees anyone that questions him as ‘unreasonable opposition’ rather than legitimate concern. Starship could crash and burn on the orbital flight and it would not make a difference at all to the ‘world’ in general. We can and have recovered from worse numerous times while advancing technology and transportation. The FACT that Musk, (and his many rapid fans) somehow “assume” that he and only he can ‘advance’ space access are very much proof that this is not about engineering, ability or purpose but strictly about ego.
To the FAA, Musk seemed to be saying, federal regulators must do their part to ensure the future arrives on schedule. Just as the 20th-century skyscrapers marked the beginning of a new era and eventually launched America into a prosperous future of finance, communication, marketing, and more, the 21st century now beckons.
The skyscraper age will soon give way to the space age.
Holding back Starship means holding back this progress, Musk wanted regulators to understand. For no longer does our vision stop in the clouds—it extends far, far beyond them. During the last five decades, humans have begun to explore the Solar System. Now it is time to extend commerce there and settle humans on new worlds. Some people oppose this vision, of course, but Musk is counting on government ultimately being on the side of industry and progress.
I ran out of superlatives already yesterday — it is just so hard to realize that this is really happening!

SpaceX’s Starship rocket is gearing up for its most ambitious test yet, and CEO Elon Musk has shared images of the rocket stacked up.
SpaceX achieved another milestone this week as the Starship and Super Heavy prototype were stacked and fully-integrated for the first time!
Once again, things are gearing up at SpaceX’s South Texas Launch Facility, located just outside the village of Boca Chica, Texas. In recent weeks, the aerospace community has been abuzz about the rollout and Static Fire test of the Super Heavy Booster 3 (B3) prototype. This was the first time a booster was tested, which will be responsible for launching the Starship to space in the near future. Since then, things have only ramped up some more.
First, there was the announcement on Aug. 2nd that the fourth Super Heavy prototype (the BN4) received a full complement of 29 Raptor engines and grid fins. This was followed on Aug. 3rd with news that BN4 was being moved to the launch pad and that the SN20 Starship prototype received a full six Raptor engines. On Aug. 6th, the denouement came with the stacking of both prototypes together, which resulted in the tallest rocket in the history of spaceflight!
Together, the integrated Starship stood around 120 meters (390 feet) tall, while the addition of the orbital launch stand increased that to 145 m (475 feet) – which is taller than the Pyramid of Giza (138.5 m; 454 ft). The stacking was the first time that the Starship and Super Heavy were fully integrated, a major milestone for the company that puts them one step closer to making an orbital flight test.
New Zealand is now set to host the first launch of the Artemis Program, as Rocket Lab is now planning to launch the CAPSTONE mission from their operational launch pad at Launch Complex 1 on the Māhia Peninsula. This is the first lunar mission for Rocket Lab, currently scheduled for launch in the fourth quarter of 2021.
“Flexible isn’t a word usually used to describe lunar missions but operating two launch complexes gives us the freedom to select a site that best meets mission requirements and schedule,” said Rocket Lab CEO and Co-Founder, Peter Beck.
AIR PLASMA BREATHING via Ground Stations, in lieu of on-board energy supply: Recently, both a German team and a Chinese team have demonstrated jet engines capable of as much thrust as a traditional jet engine, but powered only by electricity. In both cases, the engine uses large amounts of energy to turn ambient atmosphere into plasma, then jetison it via magnetic nozzles. This is to be differentiated from space ion drives, which use tiny amounts of fuel, ejected at high velocities to slowly accellerate a vehicle in free space. By contrast, this new type of engine has huge amounts of fuel available to it in the form of the ambient atmosphere. Such craft could operate in any planetary atmosphere in our solar system, whether on Venus, Earth, Mars, the gas giant or ice giant planets. The only bottleneck holding this type of engine from replacing all current airplanes is the lack of a sufficiently dense on-board energy source. The most obvious enabling technology which will allow this new type of jet, which will require no fuel for its entire lifetime—since its fuel will be the atmosphere—is fusion energy. Fusion is dense enough to fit into a small package, easily mounted on an airplane. Until fusion is obtained there is one other possibility which is currently available, which is beaming energy to a flying vehicle from ground stations. An air-plasma-breathing vehicle, whether a self-standing airplane, or a partial booster phase for a rocket to low-earth-orbit, would have to follow a trajectory within direct line-of-sight of a series of ground beaming stations. A string of such stations would be akin to a land highway, a corridior within which air traffic or space-bound vehicles could travel. Such a corridior would be easy to create. Even over ocean, aircraft carriers or other nuclear vessels could transmit large amounts of energy to such vehicles. For rockets travelling to orbit, such a system would reduce reaction mass, since a portion of its fuel would not be carried by the vehicle. File: compilation of papers on beamed energy for flying vehicles:
Beam-powered propulsion, also known as directed energy propulsion, is a class of aircraft or spacecraft propulsion that uses energy beamed to the spacecraft from a remote power plant to provide energy. The beam is typically either a microwave or a laser beam and it is either pulsed or continuous. A continuous beam lends itself to thermal rockets, photonic thrusters and light sails, whereas a pulsed beam lends itself to ablative thrusters and pulse detonation engines.
The rule of thumb that is usually quoted is that it takes a megawatt of power beamed to a vehicle per kg of payload while it is being accelerated to permit it to reach low earth orbit.
This technology is also part of the research aim of the To The Stars Academy of Arts & Sciences. I compiled the below documents to explore the research the U.S. Government and Military has already collected and what they have tested in regards to the technology.
Want to find your inner Matt Damon and spend a year pretending you are isolated on Mars? NASA has a job for you.
To prepare for eventually sending astronauts to Mars, NASA began taking applications Friday for four people to live for a year in Mars Dune Alpha. That’s a 1,700-square-foot Martian habitat, created by a 3D-printer, and inside a building at Johnson Space Center in Houston.
The paid volunteers will work a simulated Martian exploration mission complete with spacewalks, limited communications back home, restricted food and resources and equipment failures.
