Great quote from the article: "Astronauts could essentially just go there with a bucket and a shovel and get all the water they need."

Demonstrating that water could be easily located and exploited on Mars is going to have several countries thinking about getting to the Red Planet soon. I suspect that we might be on the cusp of a real Mars race similar to the moon race back in the 1960's. A colony on Mars is definitely feasible and at the very minimum and getting at least some of the human race off earth is a smart insurance policy IMO.

lotr:

How soon do you think we could colonize Mars? Certainly not by 2030, IMO, which is a date often mentioned. I doubt if we could pull it off within the next twenty years even...maybe fifty. There are too many unresolved obstacles, even with our rapidly advancing technology...not to mention funding issues.

It's a great time to be alive when we can realistically speculate about colonizing Mars, but I think it's still just a bit out of our reach, as of 2018. Maybe I'm wrong.

I'm thinking that someone is going to put human beings on Mars no later than 2035. If a real race kicks off it could happen as soon as 2030 IMO. At the same time there is going to be an explosion of unmanned voyages to Mars and we're going to learn a whole lot more about the red planet over the next decade. If we discover life or that life once existed, then I think a Mars race will automatically kick off.

Once we send human beings to Mars and bring them back again say in 2035 - 2040 I'm thinking that a permanent colony can be established within 10 years or by 2050. Once established this colony will grow fast and we may even see separate colonies established by the US, Russia & China. By 2100 at the latest we should have established a thriving, breeding colony of humans on the red planet.

Water, water everywhere!

http://www.sciencealert.com/scientis...olar-ice-water

Small pits in a large crater on the Moon's North Pole could be "skylights" leading down to an underground network of lava tubes – tubes holding hidden water on Earth's nearest neighbour, according to new research.

There's no lava in them now of course, though that's originally how the tubes formed in the Moon's fiery past. But they could indicate easy access to a water source if we ever decide to develop a Moon base sometime in the future.

Despite the Moon's dry and dusty appearance, scientists think it contains a lot of water trapped as frozen ice. What these new observations carried out by NASA's Lunar Reconnaissance Orbiter (LRO) show is that it might be much more accessible than we thought.



You just can't overstate the importance of finding accessible water on the Moon & Mars. These are the two places that make the most sense for large scale human settlement.

Here's the latest update on that very strange radio burst coming form 3,000,000,000 light years away!

https://news.nationalgeographic.com/...space-science/

About three billion light-years away, that mysterious object continually hurls humongous blasts of radio waves into the cosmos. Now, scientists have spied in those waves the spiraling signature of an extremely strong magnetic field, suggesting that the cosmic oddity exists in an intense galactic environment containing a powerfully magnetic source.

And here's one very cool theory that the burst is caused by:

“Dense tendrils of magnetized matter associated with turbulent gas surrounding a young supernova remnant would provide a comparably compelling explanation,” says Jean-Pierre MacQuart of Australia’s Curtin University.

Thar's Platinum on that thar Moon!

https://www.nextbigfuture.com/2018/0...ndustries.html

Dennis Wingo sees metals mining, communication stations and telescopes on the moon. The combination of industries will make moon development viable.

The moon is largely made up of metal oxides that could yield new supplies of platinum — perhaps enough to drive prices for the precious metal down to $300 from $1,400 an ounce today. Processing metals on the moon does not require chemicals. Different levels of heat can be used to make different metals. Cheaper platinum will make fuel cells that are so much more effective than combustion engines.

Skycorp’s mission is to fundamentally transform the spacecraft industry, utilizing orbital assembly process, electric propulsion, and modular construction, to create applications unthinkable before.


Lert's just make sure that SKYCORP is not in ANY way related to SKYNET and we're golden!

Okay I'm calling a foul on this Chinese idea:

http://www.popularmechanics.com/spac...up-space-junk/

Every space agency has a plan to get rid of space junk in the future. NASA is considering using jets of gas to slow down debris and cause it to deorbit. Europe’s thinking about sending up a satellite with a giant net to snare the debris and bring it down. Japan’s idea is to use an electric tether to do the same.

And now China has proposed a solution to the space debris problem: a giant laser that will break floating space junk into smaller and less harmful pieces. According to a paper published in the journal Optik by a group of researchers at the Air Force Engineering University in China, equipping a satellite with such a laser would be effective enough to clean up space, at least according to simulations.


As Instapundit (https://pjmedia.com/instapundit/) notes over at his blog, this sure looks like a clever way to test the military applications of space lasers without getting called out on it.

I didn't see reports of a loud noise, but I was wondering if it could have created a sonic boom capable of registering as a 2.0 quake?

According to this article the answer is NO:

https://www.popsci.com/fireball-mich...eor-earthquake

It brightened the cold Michigan night in an instant: a brilliant burst of light streaking across the sky, captured on security footage and dashboard cameras across part of the state.

Then the National Weather Service’s Detroit office tweeted out confirmation that the rock speeding through our atmosphere had caused an earthquake.

Not quite. The object did transfer some energy to the ground (either by smacking into it, or by sending the equivalent of a sonic boom through the air). But while the effect was enough to rattle some shelves and buildings, there was not nearly enough energy transfer to cause or trigger an earthquake—not even a small one.


The article then goes on to explain why this meteor didn't cause the quake.

One of these days.............................................. BOOM!

https://nypost.com/2018/01/18/skyscr...ll-buzz-earth/

Imagine a piece of rock the size of the Burj Khalifa skyscraper speeding through space 15 times faster the world’s fastest manned aircraft. Now imagine that piece of rock buzzing toward Earth on its way to making a nearby pass (and by “nearby,” we mean more than 11 times the distance between our planet and the moon).

Here's a cool innovation that might be the key to powering a Martian colony:

https://www.popsci.com/nuclear-reactors-mars

The cylinder of uranium is the size of a coffee can. Even with its shielding and detectors, the device is still no larger than a wastepaper basket. But this little prototype, soon to be tested in the Nevada desert, fuels a dream of an off-world future for humanity.

The Kilopower project, a joint venture between NASA and the Department of Energy, is set to be the first nuclear fission reactor to reach space since the SNAP 10A project in the 1960s. A prototype is in testing, which makes it closer to launch than any of the other projects that popped up in the intervening decades.


My first thought was "wow, this would be great for right here on Earth". Then I considered how some ding bat might fiddle with their home nuke reactor and figured it's probably better if we keep these things off earth.
