Rare-earth metals and other minerals are essential for green tech like EVs and renewable energy. Trouble is, we need a lot of them and their availability on Earth is limited. But what if we could tap into all the materials flying around in space? Some scientists claim we could mine asteroids in the future. Yes, asteroids. Is it just an Armageddon remake or will we eventually
dig into them
?

Scientists just took a big step toward mapping out the structure of the universe

Researchers observed more than 500 of these mysterious cosmic explosions, unraveling the hidden nature of their sources.

The most popular theory suggests that FRBs come from neutron stars, the collapsed cores of massive stars. Scientists believe that the explosions could be a result of a specific type of neutron star known as a magnetar, named so for their powerful magnetic fields, thousands of trillions of times more powerful than Earth’s fields.

“The reason we think that’s true is because they are the only thing that we know of that could plausibly produce such energetic flashes in such a short duration of time,” Masui said. “Otherwise, we don’t really know how they’re created.”

Located at the Dominion Radio Astrophysical Observatory in British Columbia, Canada, the CHIME telescope began operating in 2018. The stationary telescope is made up of four giant cylindrical radio antennas.

Zhurong Rover dropped Camera on Mars to make group photos at Utopia Planitia (Chinese Tianwen-1)

On June 11, 2021 CNSA published new Hi-Res Mars images Zhurong Rover (Chinese Tianwen-1 mission) with amazing details of Utopia Planitia on Red Planet. Rover dropped/deployed special instrument camera to make group images. Camera made first shot capturing Mars Lander and Zhurong Rover together in single frame. Resolution of the images is incredible. Chinese Zhurong Mars Rover has been working on the surface of Mars for 26 Martian days, carrying out environmental perception, fire surface movement, and scientific exploration. Zhurong also made first panoramic 360 degrees image at Utopia Planitia on Mars. There is image of Parachute pack and Heat Shield on the surface of Red Planet.

This Drone Bus Will Carry 40 Passengers Between Cities for the Price of a Train Ticket

He’s got a point. There’s a lot more space in the sky than on the ground, obviously, but flight paths need to be carefully planned and contained within specific areas, particularly in and near big cities. If flying taxis became affordable enough for people to use them the way we use Uber and Lyft today, there would quickly be all sorts of issues with traffic and congestion, both in the sky and with takeoff and landing space on the ground. So why not take a scaled approach from the beginning?

Speaking of affordability, Kelekona says that’s a priority, too. It may play out differently, especially in the technology’s early stages, but the intention is for tickets on the drone bus to cost the same as a train ticket for an equivalent distance. The first route, from Manhattan to the Hamptons, will reportedly have a 30-minute flight time and an $85 ticket price.

Other intended routes include Los Angeles to San Francisco, New York City to Washington DC, and London to Paris—all in an hour, which is comparable to the time it takes for a regular flight right now. One of the differences, ideally, will be that the eVTOLs will be able to land and take off closer to city centers, given that they won’t require long runways.

Seraphim Capital unveils worlds first listed space technology fund

TAMPA, Fla. — Seraphim Capital plans to trade stakes it has amassed in space technology startups on the public market through an investment trust.

The Seraphim Space Investment Trust will eventually comprise bets in 19 international startups, including satellite data specialist Spire Global, quantum encryption firm Arqit and space-based cellular network operator AST Space Mobile.

Those three recently got valuations of more than $1 billion in mergers with special purpose acquisition companies (SPACs), investment vehicles that offer another route to public markets.
