NASA contracts energy firm to refine nuclear thermal propulsion concepts

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

As the U.S. government continues to pursue plans for a crewed mission to Mars, NASA has contracted with BWXT Nuclear Energy Inc. of Lynchburg, Virginia, to advance concepts in Nuclear Thermal Propulsion (NTP), which could drastically reduce travel times to Mars.

This is part of NASA’s Game Changing Development Program, which takes ideas from academia and industry as well as NASA and other government programs, to advance new approaches to space technologies to accommodate the changing needs of U.S. space efforts.

NTP is not a new concept, but it was abandoned in 1972 when plans for a Mars mission were shelved. NASA conducted ground tests since 1955 to determine the viability of NTP and has occasionally been revisited as a conceptual part of Mars mission feasibility studies.

NASA may alter the DNA of astronauts who journey to Mars

Posted by in categories: biotech/medical, space travel

NASA’s acting chief technologist, Dr Douglas Terrier, made the comments ahead of an appearance at the Codex innovation summit, held in London.

One of the techniques currently under development that it is following is NMN, a compound expected to enter clinical trials after it was shown to rejuvenate elderly mice in laboratory tests.

This Overlooked Theory Could Be The Missing Piece That Explains How The EM Drive Works

Posted by in categories: quantum physics, space travel

Ever since the EM drive first made headlines, science lovers have puzzled over how the propulsion system seems to produce thrust, despite the fact it’s ‘impossible’ according to one of the most fundamental laws of physics — Newton’s third law of motion.

Now a team of physicists have put forward an alternative explanation — it turns out the EM drive could actually work without breaking any scientific laws, if we factor in a weird and often overlooked idea in quantum physics — pilot wave theory.

For those who need a refresher, the crux of the problem here is that the EM, or electromagnetic, drive appears to produce thrust without any fuel or propellant.

New space race to Mars pits NASA vs. SpaceX

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

Entrepreneur Elon Musk’s announcement last week accelerating plans for manned flights to Mars ratchets up political and public relations pressure on NASA’s efforts to reach the same goal.

With Musk publicly laying out a much faster schedule than NASA — while contending his vision is less expensive and could be financed primarily with private funds — a debate unlike any before is shaping up over the direction of U.S. space policy.

Elon Musk: SpaceX Is Coming for Mars in 2022

Posted by in categories: Elon Musk, space travel

Musk said he’s “confident” the plan will be under way within five years.

“I can’t think of anything more exciting than going out there and being among the stars,” Musk said, adding that he thinks SpaceX has figured out a way to make it affordable by using revenues from the company’s satellite launches, service missions to the International Space Station and by making smaller, more efficient rockets that are mostly reusable.

Nine years after SpaceX’s first successful launch — its fourth ever — Musk said his engineers are now perfecting propulsive landing. He believes the BFR rocket can carry out missions to the moon and back without producing propellant, enabling the establishment of a lunar space station.

SpaceX’s Musk unveils plan to reach Mars by 2022

Posted by in categories: Elon Musk, space travel

Futurist and inventor Elon Musk unveiled ambitious plans Friday to send cargo ships to Mars in five years and use rockets to carry people between Earth’s major cities in under half-an-hour.

The founder of SpaceX said a planned interplanetary transport system, codenamed BFR (Big Fucking Rocket), would be downsized so it could carry out a range of tasks that would then pay for future Mars missions.

“The most important thing… is that I think we have figured out how to pay for (BFR),” Musk told a packed auditorium at a global gathering of experts in Adelaide.

Lockheed Martin unveils fully reusable crewed Martian lander

Posted by in category: space travel

NASA’s goal to reach Mars is just over a decade away, and Lockheed Martin revealed Thursday how humans might soon walk upon the red planet’s surface.

Lockheed Martin gave CNBC a first look at its new spacecraft prototype, which the company will unveil Thursday at this year’s International Astronautical Congress in Adelaide, Australia.

“This is a single-stage, completely reusable lander which will be able to both descend and ascend,” said Lockheed Martin’s Robert Chambers.

Machs Effect interstellar propellentless propulsion mission proposal at NASA NIAC

Posted by in categories: materials, space travel

Finally Mach Effect propulsion had gotten useful levels of funding and will get a validation test with NASA. They reported interim results and have made good progress. Nextbigfuture covered the announcement of funding by NASA NIAC for mach effect propulsion in April 2017. They now have presented the new experiments and path forward with the needed materials to clearly prove significant propulsion and unambiguous space experiments. They have advanced the experimental work and will get test state-of-the-art PIN-PMN-PT materials. They have demonstrated a Force versus Voltage scaling relationship that is consistent with the theory. They have a roadmap to continue.
