The McKay-Zubrin plan for terraforming Mars in 50 years was cited by Elon Musk.

Orbital mirrors with 100 km radius are required to vaporize the CO₂ in the south polar cap. If manufactured of solar sail-like material, such mirrors would have a mass on the order of 200,000 tonnes. If manufactured in space out of asteroidal or Martian moon material, about 120 MWe-years of energy would be needed to produce the required aluminum.

The use of orbiting mirrors is another way for hydrosphere activation. For example, if the 125 km radius reflector discussed earlier for use in vaporizing the pole were to concentrate its power on a smaller region, 27 TW would be available to melt lakes or volatilize nitrate beds. This is triple the power available from the impact of a 10 billion tonne asteroid per year, and in all probability would be far more controllable. A single such mirror could drive vast amounts of water out of the permafrost and into the nascent Martian ecosystem very quickly. Thus while the engineering of such mirrors may be somewhat grandiose, the benefits to terraforming of being able to wield tens of TW of power in a controllable way would be huge.

Last month, Elon Musk’s Neuralink, a neurotechnology company, revealed its plans to develop brain-reading technology over the next few years. One of the goals for Musk’s firm is to eventually implant microchip-devices into the brains of paralyzed people, allowing them to control smartphones and computers.

Although this Black Mirror-esque technology could hold potentially life-changing powers for those living with disabilities, according to Cognitive Psychologist Susan Schneider, it’s not such a great idea, and I can’t help but feel relieved, I’m with Schneider on this.

Tesla CEO Elon Musk says that the automaker is working on a new battery pack to come out next year which will last 1 million miles.

When talking about the economics of Tesla’s future fleet of robotaxis at the Tesla Autonomy Event yesterday, Musk emphasized that the vehicles need to be durable in order for the economics to work:

SpaceX’s silver Starhopper prototype could complete its biggest hop test this weekend, according to SpaceX CEO Elon Musk.

Starhopper, which is an early prototype for SpaceX’s Starship spacecraft, has completed a couple of tests so far. According to Musk, the Starhopper’s next challenge will be to fly roughly 650 feet off the ground. Musk recently tweeted that the prototype’s next major hop could take place on Aug. 16, Aug. 17, or Aug. 18, as long as the U.S. Federal Aviation Administration (FAA) gives SpaceX permission to conduct the test flight.

Just spoke with FAA, so hopefully yes.

How much would it cost to build a city on Mars? According to Elon Musk over the weekend, it could be the most expensive construction project in human history — and cost up to an eighth of the value of the entire global economy.

The SpaceX CEO’s vision includes not only sending the first humans to Mars, but to use that mission as a starting point to build a permanent settlement. Assuming all goes to plan, Musk believes that a self-sustaining city could take shape as early as 2050.

What happens after that point is anyone’s guess. Inverse has spoken to experts from a number of fields, who have flagged a series of issues those first inhabitants will need to address. They could mutate and develop new physical attributes, they could find the city’s confines stifling and develop a national identity, and they could develop a new, ground-up economy.

The company will soon start employing a second net-equipped boat during orbital launches, in an attempt to snag both halves of its rockets’ payload fairings before they splash down in the ocean, SpaceX founder and CEO Elon Musk confirmed via Twitter on Friday (Aug. 9).

In the last week alone, SpaceX’s twin orbital Starship prototypes have made some truly jaw-dropping progress. Onlookers have witnessed Florida’s Starship push through a rapid growth spurt, while the company’s Texas team has begun to install propellant tank bulkheads and work on a triple-Raptor thrust structure.

Meanwhile, SpaceX CEO Elon Musk has suggested that one or both of the orbital-class Starship prototypes could be “almost ready to fly” by August 24th, the date of the CEO’s next official update on Starship (formerly BFR and ITS). Although the actual challenge of building a massive, orbital-class launch vehicle is far subtler than the visible steelwork needed to build its primary structure and pressure vessels, the veritable leaps forward made in both Texas and Florida in the last 7–10 days are extremely encouraging signs.

Starting off in Boca Chica, Texas, SpaceX’s team of engineers and technicians have been simultaneously handling Starhopper’s first untethered flight test (completed on July 25th) and building the facility’s orbital-class Starship prototype. Most significantly, after a few days of preparation, what is likely the Texas Starship’s first bulkhead was lowered inside its ~25m-tall (80 ft) barrel section, composed of the spacecraft’s propulsion section and propellant tanks.

The reusability is a key aspect, as Musk has said each engine needs to be capable of flying up to 1,000 times to support the ambitious operations of Starship. That’s a major challenge; the most re-used engines in space exploration history were the main engines on each Space Shuttle, which flew up to only a few dozen times each. “It’s quite ambitious,” says Dodd. “I don’t know if 1,000 flights is necessarily going to be achievable in the near future. If it lives up to its potential, maybe 1,000 is within the realm of possibility one day.”

SpaceX’s existing engine is called Merlin, which is used on its operational Falcon 9 and Falcon Heavy rockets, but Raptor heralds a significant improvement. One is that it has double the thrust of its predecessor thanks to a much higher pressure, 380,000 pounds of thrust at sea level versus 190,000 pounds, despite being a similar size.

This new tech is the product of Neuralink, a company that Elon founded in 2016 with a goal of creating an implantable brain-computer interface (BCI) and yes, it is as crazy as it sounds.

He stated that the initial goal with this is to enable people with quadriplegia (paralysis) to control a smartphone or computer with just their thoughts. But anyone that knows the entrepreneur knows that he intends to go bigger than that.

His vision also consists of giving humans the ability to “merge” with AI and therefore give them superhuman intelligence. This is what may then seem like an objective that is too hype to be an actual plan for new technology development.
