NASA Completes early tests of mini nuclear fission Reactor which could Power human Settlements on Ma

Source: Newsweek

NASA has successfully completed tests of a miniature nuclear reactor which could one day power long-term human settlements on the Moon, Mars and beyond.

Kilopower, as the system is known, is a small, lightweight fission reactor which will be capable of producing up to 10 kilowatts of electrical power—enough to run several households continuously for 10 years. Just four of these reactors would be sufficient to power a Martian outpost, according to NASA.

A reliable and efficient power system will be an essential part of future space missions as humans begin to settle other worlds, enabling outposts to be self-sufficient. The new reactor will provide the power for lighting, water and oxygen, as well as for running experiments and producing fuel. This capability will mean astronauts won't have to take all the resources they need with them, opening up new possibilities for exploration.

The reactor will be especially useful in the challenging environments of places such as the Moon and Mars where generating power using solar panels can be difficult. On Mars, for example, sunlight is limited by seasonal variation and periodic dust storms which can last for months. Meanwhile, night time on the Moon lasts around 14 days.

Thu May 3, 2018, 08:04 AM

with religious missionaries in tow

I'm not getting the benefits of space exploration. OK, minerals, new research and knowledge. We have more than we are able to handle profitably or responsibly here on earth.

We're going to sink hundreds of billions of dollars on exploration with a light payoff. Unless they bring home minerals - gold, platinum, silver, palladium. This will be the gold standard effect of Quantitative Easing because it would expand the money supply without economic activity to back it up. It would be very inflationary, as much as the Conquistadors bringing home gold to the King of Spain from South America. France too. They had price inflation after the precious metals started arriving.

People can't heat their homes here. We're building fission mini-reactors for celestial gadflying. This is something Trumpers understand, in ways that we liberals sometimes don't.

Yes, we are on the verge of bringing back treasures from the sky, but the real value never left the Earth.

The modern world was transformed by the space age, and its benefits are all around you, including the medium used to send your post. Relatively, space exploration and research is a very cost effective investment when compared to most government expenditures.

Can you really not see a connection between powering settlements on Mars and powering your town?

This is the usual, you know. Most of our scientific and technical advances start in research that has no immediate practical application. Not that this is a start, that already happened. This is a move to practical application. And if it happens this way because this program has the funding to do it in spite of government dominated by knuckle-dragging profiteers, well, that's the way it is.

Isn't that marvelous, though? Research for the sake of knowledge and hope of future advances. Visionary research that leads to advances in wellbeing for mankind.

THIS is another big reason why we elect Democrats.

Your big point in your biggest paragraph is price inflation. Not much of a downside that.

Even that it would occur is debatable.

But you have stated in this thread that you don't want a debate. That won't stop people from replying to you.

I don't know if the technology is there yet to build a ship with rotating arms to mimic gravity. I am not saying that we will never go to and inhabit other planets or moons in out solar system.

They have done that in order to enable deep-space missions.

What if our ancestors had said "The wildlife, the climates, the native inhabitants of the Americas are too dangerous! We should just stay in Europe/Asia." Well, OK several massive genocides in the Americas would have been averted. But aside from that, I wouldn't exist and there's a good chance you wouldn't either. Nor would the American Experiment in democracy have ever been performed. Up until 2017, the entire world benefitted from that.

They did not worry about micrometeorites or radiation or bone loss or blood not pooling down. There is a big difference between exploring Earth and exploring space. What about Earth, so far we have explored only 5% of the oceans. There is more than enough of Earth that has not been explored to last decades.

Such as scurvy. But they did it anyway. Without the explorers who traveled all over the world humans would be isolated on our separate continents.

Humans have always explored and pushed the limits of their physiologies to the limit. Just the other day an article was posted in the Science group here about tools dated to 700,000 years ago being found on the Philippine island of Luzon. Even our pre-modern human ancestors pushed their limits to explore their universe.

Why should we stop exploring now?

40. True - and it is appalling that the Columbus "discovery" is still taught
Thu May 3, 2018, 05:10 PM
May 2018

Last fall I read two books by Charles Mann, "1491" and "1493", that covered the state of the world before Columbus and his ilk arrived in the Americas. Then I read Gavin Menzies books, "1421" and "1434" in which he posits that the Chinese got to the Americas and mapped nearly the entire world seventy years before Columbus (in "1421&quot .

Today I pulled out a book my grandfather was given in 1904, Mabie's Popular History of the United States 1897 and in the first chapter they talk about how the Vikings discovered America.

Mann had problems with the Columbus discovery but he does claim that Columbus ushered in a huge economic shift in the world which he mostly covered in "1493" ("1491" mostly covers the state of the Americas prior to Columbus' arrival). Menzies seems to be sinocentric rather than eurocentric and discounts what earlier occupants of the Americas had done. In "1434" Menzies even gives the Chinese credit for the European Reformation crediting the Chinese with every single advance of that period. While there may have been influences

Humans found the "New World" over and over and over. Even "Native Americans" arrived in various waves. No one person or culture can claim it as their discovery!

The idea that fundamental research for the acquisition of knowledge alone is not worth doing is anathema to me. There is simply no better use of public dollars than research that opens up new possibilities and technologies that have no chance of being discovered through purely "market forces".

I would support a 100% force reduction in the US military before I would support cutting one more dollar from basic research...the former is defending the past and those who already gained from it, helping them keep more for themselves and less for everyone else; the latter is for the benefit of all in the long run and a forward looking approach to government's role.

I strongly suspect trolls are here among us and posting this kind of stuff to take everyone's eye off the ball and the crimes that Trump and the GOP are committing (and getting away with) daily...

I'm enthusiastic about space exploration but I don't see any reason to put humans in space beyond low earth orbit.

Our robots keep getting better and better and space is an extremely hostile environment for humans.

"The Martian" is an enjoyable movie, but the environment of Mars is much more difficult than the movie depicted. Beyond low earth orbit radiation (x-rays, gamma rays, high energy particles...) cause significant damage to the human body. People traveling to and living on the Moon or Mars, or on deep space stations, will suffer shorter lifespans and poorer health.

I doubt humans will ever have a significant presence beyond Earth, but maybe our intellectual offspring will, for example, artificial intelligences with robotic bodies, creatures that can walk around on the surface of the Moon or Mars or crawl around the outside of a spacecraft naked, powered by fission reactors like this.

Thu May 3, 2018, 05:20 PM
May 2018

Visitors to the International Space Station are shielded by the Earth's magnetic field only. They are still exposed to very significant and unhealthy ionizing radiation. Presumably everyone who visits the ISS can do the math and has accepted the increased risks of cancer and other serious health problems in their futures.

Colonists on the Moon or Mars would have to live underground in lava tubes, tunnels, etc., to avoid this radiation. Space suit visits to the surface would have to be rare. The habitat of "The Martian" movie doesn't work without magic.

Humans traveling to Mars on chemical rockets approaches insanity. Two years in ionizing radiation hell. So many things can go wrong.

Nuclear electric rockets would reduce the dangerous transit time to Mars considerably. Constant acceleration to halfway point, flip, constant deceleration to Mars. Travel time measured in weeks.

Nuclear power plants like the Kilopower system would keep the lights on and the air breathable in any off-planet Earth habitat.

But I'd still bet on Artificial Intelligence and robots before any significant human presence in outer space.
