SpaceX’s Dragon completes record-setting third Space Station resupply mission

Posted by in categories: robotics/AI, space travel

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.

Police urge residents in Texas town to vacate homes during nearby SpaceX rocket launch

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.”

NASA’s James Webb Space Telescope

Posted by in category: space travel

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).

Going up: Watch SpaceX’s Starhopper soar to new heights

Posted by in category: space travel

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.

SpaceX launched its sub-scale Starship “hopper” spacecraft on a brief unpiloted up-and-down test flight at the company’s Boca Chica, Texas, test facility Tuesday, a dramatic demonstration of rocket technology intended to pave the way to a new, more powerful heavy lift booster and, eventually, crew-carrying interplanetary spacecraft.

These Researchers Want to Run a Cable From the Earth to the Moon

Posted by in categories: materials, space travel

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.

Physicists Just Released Step-by-Step Instructions for Building a Wormhole

Posted by in categories: cosmology, physics, space travel

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.

NASA’s Psyche Mission Has a Metal World in Its Sights

Posted by in categories: engineering, space travel

Designed to explore a metal asteroid that could be the heart of a planet, the Psyche mission is readying for a 2022 launch. After extensive review, NASA Headquarters in Washington has approved the mission to begin the final design and fabrication phase, otherwise known as Phase C. This is when the Psyche team finalizes the system design, develops detailed plans and procedures for the spacecraft and science mission, and completes both assembly and testing of the spacecraft and its subsystems.

“The Psyche team is not only elated that we have the go-ahead for Phase C, more importantly we are ready,” said Principal Investigator Lindy Elkins-Tanton of Arizona State University in Tempe. “With the transition into this new mission phase, we are one big step closer to uncovering the secrets of Psyche, a giant mysterious metallic asteroid, and that means the world to us.”

The mission still has three more phases to clear. Phase D, which will begin sometime in early 2021, includes final spacecraft assembly and testing, along with the August 2022 launch. Phase E, which begins soon after Psyche hits the vacuum of space, covers the mission’s deep-space operations and science collection. Finally, Phase F occurs after the mission has completed its science operations; it includes both decommissioning the spacecraft and archiving engineering and science data.

Russian Health Officials Blame ‘Fukushima Crabs’ for Cesium-137 Exposure After Mysterious Accident

Posted by in categories: health, nuclear energy, space travel

A doctor who treated survivors of a mysterious nuclear accident in Russia was told that the radioactive isotope cesium-137 must have made its way into their body due to “Fukushima crabs,” according to CNN.

The August 8 incident at the Nyonoksa testing range on a platform in the White Sea has not yet been fully explained, but at least seven individuals have been reported dead after what nuclear agency Rosatom described as an accident involving an “isotope power source for a liquid-fuelled rocket engine.” It later emerged that the incident was serious enough that Russian officials in Arkhangelsk wavered over the issue of whether to issue evacuation orders for nearby towns. While several of the personnel deaths were due to an onsite explosion, the Washington Post reported this week (citing the Novaya Gazeta newspaper) that two individuals had died of radiation exposure before they could be taken to Moscow for treatment.
