(SCRUBBED) Watch SpaceX’s Starhopper come alive for the second time, as it attempts a 150 Meter test hover.

A Tesla Roadster launched into space with a spacesuit-clad mannequin at the wheel has completed its first lap of the sun.

SpaceX, the aerospace company founded by Elon Musk, was blasted into orbit from Cape Canaveral last year and it is hoped that it will veer close to Mars and Earth during the course of its time among the stars.

According to tracking website Where Is Roadster?, the red sports car has now completed a solar orbit, having been cruising through the void for more than 18 months.

A SpaceX Dragon capsule that set down in the Pacific Ocean on Tuesday after having been docked at the International Space Station since late July became the first such vehicle to do three of those trips. SpaceX uses its Dragon cargo capsule to ferry experiment materials, supplies and more to and from the ISS, and it also refurbishes and reflies these capsules when possible as part of its ongoing mission to make spaceflight more reusable, and therefore more economical.

After it splashed down yesterday, SpaceX recovered the capsule from the ocean and returned it to shore. The vehicle is loaded with return cargo from the ISS, with almost 2,700 pounds of materials and results from experiments, which NASA staff on the ground will now examine and study. Dragon carried more than 5,000 pounds of stuff to the Space Station, and over half of that was related to science and research missions. One of the return cargo items is actually a spherical robot called CIMON, and is basically a space-based smart speaker companion.

A public safety notice was issued to residents of Boca Chica, a town on the southern tip of Texas with houses within two miles of SpaceX’s launch pad for the Starhopper rocket, Business Insider reported on Sunday.

A county sheriff reportedly went door-to-door on Saturday to deliver the notice to approximately 20 households, warning of possible shattered windows and “potential risk to health and safety.”

The #USOpen starts today! Can you imagine a spacecraft the size of a tennis court? To see infrared light from faraway objects, the James Webb Space Telescope needs to be extremely cold! Enter Webb €™s sunshield (~21x14 meters in size), which will provide shade and keep Webb operating at less than ~50 Kelvin (−370 °F or −223 °C).

A prototype of the Starship spacecraft that SpaceX hopes to one day send to Mars has had its second outing, and a hugely successful one at that. The Starhopper completed its second test hop at the company’s Boca Chica test facility in Texas today, reaching its highest altitude yet before returning safely to solid ground.

A fully developed Starship would offer the carrying capacity needed to deliver dozens of people and cargo to the surface of Mars, though there is a long way to go before that happens.

It would be much easier to escape Earth’s gravity if you could skip the energy-intensive rockets.

That’s the idea behind the Spaceline, a newly-proposed type of space elevator that would link the Earth and the Moon in a bid drastically cut the cost of space travel.

Described in research published to the preprint server ArXiv by researchers at Columbia University and Cambridge University, the Spaceline would be tethered to the surface of the Moon and dangle down into geostationary orbit around the Earth like a plumb bob, waiting for astronauts to latch on and ride into the cosmos. The proof-of-concept paper found that the Spaceline could be constructed out of materials that exist today, raising the possibility of easier space travel and perhaps even orbital settlements.

I am going home :3.

Everybody wants a wormhole. I mean, who wants to bother traveling the long-and-slow routes throughout the universe, taking tens of thousands of years just to reach yet another boring star? Not when you can pop into the nearest wormhole opening, take a short stroll, and end up in some exotic far-flung corner of the universe.

There’s a small technical difficulty, though: Wormholes, which are bends in space-time so extreme that a shortcut tunnel forms, are catastrophically unstable. As in, as soon as you send a single photon down the hole, it collapses faster than the speed of light.
