Rocket Report: SpaceX gets Moon launches, South Korean rocket, BE-4 wins
Posted by Genevieve Klien in categories: Elon Musk, space travel
Welcome to Edition 1.19 of the Rocket Report! Lots of news this week about the development of rocket engines in the United States, South Korea, and elsewhere. There are also milestones for the Ariane 5 rocket and an anniversary for SpaceX.
As always, we welcome reader submissions, and, if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.
SpaceX hits 10 years since the Falcon 1. In an in-depth feature, Ars recounts the harrowing eight weeks following the failed third flight of the Falcon 1 rocket and the finally successful fourth flight. “If we had not reached orbit on that attempt, SpaceX would not exist,” Elon Musk recalled. “That was a very tough launch emotionally.” Shortly after the Falcon 1 launch, SpaceX intensified work on developing its workhorse Falcon 9 rocket.

Det er da selvfølgelig et neurostimulations-pandebånd. Georg Gearløs’ tænkehat findes nu i virkeligheden. Det er noget med at bestemte områder i hjernen får tilført meget små impulser af strøm — man kan indstille den så den øger koncentrationsevnen — eller kreativiteten! Efter sigende. Skal jeg have den på næste gang jeg freestyler? Selvfølgelig skal jeg det. Glæder mig til at aflægge rapport PlatoScience 😬

A Base on Mars? It Could Happen by 2028, Elon Musk Says
Posted by Paul Gonçalves in categories: Elon Musk, space travel
Humanity could have an outpost on Mars just a decade from now, Elon Musk said.
Musk’s company SpaceX is building a huge, reusable rocket-spaceship duo called the BFR to help our species explore and settle Earth’s moon, Mars and other worlds throughout the solar system.
The billionaire entrepreneur’s long-term vision involves the establishment of a million-person city on the Red Planet in the next 50 to 100 years. But we could get the founding infrastructure of such a settlement — an outpost Musk calls Mars Base Alpha — up and running much sooner than that, he said.

Trust: the inside story of the rise and fall of Ethereum
Posted by Derick Lee in categories: bitcoin, cryptocurrencies, law
But there’s a catch: what about the faithful ‘execution’ of a contract? Doesn’t that require trust as well? What good is an agreement, after all, if the text is there but people don’t respect it, and don’t follow through on their obligations? Which brings us back to the crucial matter of how Buterin managed to piss off so many people.
The great cryptocurrency heist.
Blockchain enthusiasts crave a world without bankers, lawyers or fat-cat executives. There’s just one problem: trust.

Asteroids have been hitting the Earth for billions of years. In 2022, we hit back

Payback time.
DART is a test of the kinetic impactor technique, a potential method to deflect an asteroid on course to impact the Earth. Kinetic impactors are one of only a small number of approaches we think are mature enough to deploy in the near future if they are needed (though we hope they won’t be). The most powerful asteroid-deflection technique is the use of a nuclear device. While such a device makes for good (and bad) sci-fi movies, there is widespread desire to develop alternate techniques.
The kinetic impactor concept is rather straightforward: ram the threatening object with a spacecraft and change its orbit so that it misses our planet. In theory, we could heave ever-larger masses at ever-faster speeds to deflect ever-larger objects. However, we think there is a practical limit — we don’t want to break up an incoming object into several pieces, lest we replace one big impact with multiple, only-slightly-smaller impacts. Exactly where that tradeoff lies is still uncertain, but we believe we can keep an object intact if we change its speed by less than the object’s own escape speed. In other words, since we think a lot of these objects are loose aggregates of gravel held together by gravity, we don’t want to shove so hard that we accidentally overcome that weak gravity and disperse the gravel.
