NASA –Faster-than-Speed-of-Light Space Travel? “Will ‘Warp Bubbles’ Enable Dreams of Interstellar Voyages?”

Posted by in categories: quantum physics, space travel

A number of NASA scientists are currently researching the feasibility of warp drive (and EMdrive and a number of other modes of faster than light travel); however, most scientists think that such forms of space travel simply aren’t viable, thanks to the fundamental physics of our universe.

“Routine travel among the stars is impossible without new discoveries regarding the fabric of space and time, or capability to manipulate it for our needs,” says Neil deGrasse Tyson, the “Cosmos famous” astrophysicist at the American Museum of Natural History, said “By my read, the idea of a functioning warp drive remains far-fetched, but the real take-away is that people are thinking about it — reminding us all that the urge to explore continues to run deep in our species.”

There have been hints the past few years that NASA may be on the path to discovering warp bubbles that could make the local universe accessible for human exploration. NASA scientists may be close announcing they may have broken the speed of light. According to state-of-the art theory, a warp drive could cut the travel time between stars from tens of thousands of years to weeks or months.

Echoless light could help send signals through walls and skin

Posted by in categories: biotech/medical, internet, space travel

In 1948, physicist Leonard Eisenbud proposed a particular way of transmitting the waves to overcome this. But not until now have researchers made it happen.

By Michael Slezak.

It’s a call with no response. A new way of creating waves – whether of light, radio or sound – that don’t echo promises to improve everything from your Wi-Fi signal to medical imaging to shining lasers through space.

SpaceX moves Starhopper back to launch pad, puts 200m hop test on the calendar

Posted by in categories: robotics/AI, space travel

On July 28th, SpaceX wrapped up modifications to a rented robotic lift vehicle and carefully moved Starhopper back to its launch facilities three days after its inaugural flight. Another two days after that, SpaceX filed road closure requests confirming the date for the Starship prototype’s next launch.

According to those road closures, SpaceX is preparing Starhopper for a second flight just 17 days after its first hop and has cordoned off August 12th through the 14th to provide a backup window or two and a possible pre-flight static fire opportunity. In recent days, SpaceX has begun the process of refurbishing Starhopper and its pad facilities, although – by all appearances – very little work is needed to return the vehicle to flight readiness.

In fact, just yesterday (July 30th), SpaceX began reattaching the pad’s quick-disconnect (QD) umbilical ports to Starhopper in an important post-flight test and a first step towards verifying that all ground support equipment (GSE) is healthy. Thankfully for the pad, Starhopper is powered by just one Raptor engine, producing a maximum of 200 tons (450,000 lbf) of thrust at sea level.

NASA agrees to work with SpaceX on orbital refueling technology

Posted by in categories: engineering, food, robotics/AI, space travel, sustainability

On Tuesday afternoon, NASA announced 19 new partnerships with 10 US companies to help bring more cutting-edge technologies closer to production use in spaceflight. There were a lot of useful engineering ideas here, such as precision landing systems and robotic plant farms, but perhaps the most intriguing one involved the rocket company SpaceX and two of NASA’s field centers—the Glenn Research Center in Ohio and the Marshall Space Flight Center in Alabama.

“SpaceX will work with Glenn and Marshall to advance technology needed to transfer propellant in orbit, an important step in the development of the company’s Starship space vehicle,” the NASA news release states. This is a significant announcement for reasons both technical and political.

The wild physics of Elon Musk’s methane-guzzling super-rocket

Posted by in categories: Elon Musk, physics, space travel

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.

SpaceX to mature Starship Moon landing and orbital refueling tech with NASA’s help

Posted by in categories: food, space travel

NASA has announced 19 technology partnerships between the agency’s many spaceflight centers and 13 companies, including SpaceX, Blue Origin, and more. This round of Space Act Agreements (SAAs) shows a heavy focus on technologies and concepts that could benefit exploration of the Moon and deep space more generally, including lunar landers, food production, reusable rockets, and more.

Put simply, all 19 awards are great and will hopefully result in tangible products and benefits, but SpaceX has a track record of achievement on the cutting edge of aerospace that simply has not been touched over the last decade. As such, the company’s two SAAs are some of the most interesting and telling, both ultimately focused on enabling Starship launches to and landings on the Moon and any number of other destinations in the solar system. Perhaps most importantly, it signals a small but growing sect within NASA that is willing and eager to acknowledge Starship’s existence and actively work with SpaceX to both bring it to life and further spaceflight technology in general.

One agreement focuses specifically on “vertically land[ing] large rockets on the Moon”, while the other more generally seeks to “advance technology needed to transfer propellant in orbit”, a feature that Starship’s utility would be crippled without. In this particular round of SAAs, they will be “non-reimbursable” – bureaucratic-speak for a collaboration where both sides pay their own way and no money is exchanged. SpaceX’s wins ultimately show that, although NASA proper all but refuses to acknowledge Starship, the many internal centers it is nothing without are increasingly happy to extend olive branches towards the company and its ambitious next-generation rocket.

NASA Selects Dozen U.S. Companies For Moon To Mars Partnerships

Posted by in categories: materials, space travel

NASA selects key commercial partnerships to further its new Moon to Mars strategy.

Today, NASA announced it has selected 12 U.S. commercial companies for 19 partnerships in its crewed Moon to Mars efforts, which kicks off with a planned 2024 Artemis program crewed return to the lunar surface.

The selections entail six key areas for future development as well as a category for other exploration technologies. They are: advanced communications, navigation and avionics; entry, descent and landing; in-space manufacturing and assembly; advanced materials; power; and propulsion.

NASA to help SpaceX, Blue Origin, and more develop technologies for Moon and Mars travel

Posted by in category: space travel

As NASA forges ahead to the Moon — and eventually to Mars — the agency is hoping to get some help from the commercial space industry. Today, NASA announced new partnerships with various aerospace organizations, aimed at advancing technologies related to landing on other planets, navigating the lunar surface, transferring propellant in space, and more — all of which could be critical for future missions.

Ten companies now hold a total of 19 partnerships with NASA through the agency’s Announcement of Collaborative Opportunity initiative, or ACO. In October, NASA put out a call for proposals from the industry, asking them to detail different technologies they’d like to develop through the program. Now, the companies that have been selected will be given expertise and resources from various NASA centers to help mature these space technologies — at no cost to the companies themselves.
