I guess you can file this under "good news/bad news":

http://groundbasedspacematters.com/i...space-workers/

So far they have kept OSHA at bay with respect to enforcing workplace safety rules in space. And it shows just how mainstream space exploration is becoming if the OSHA & lawyers are becoming involved. On the other hand the more lawyers & OSHA stick their nose into space based industries progress will grind to a halt.

China is pushing harder & faster into space exploration:

http://www.bbc.com/news/world-asia-china-39880165

This series of experiments is designed to study how crews will react to extended stays on the Moon. They will spend up to 200 days in an enclosed system cabin called the Yuegong 1 (lunar Palace - does China have truth in advertising?). This type of effort is a clear indication that China is serious about extended manned space flight.

More on the developing space race with China:

http://www.scmp.com/news/china/polic...nt-and-capture

A couple of thoughts:

* This would be an ambitious undertaking and the idea of grabbing an asteroid, placing it in Lunar orbit and then developing the expertise to mine it is pretty audacious.

* In the next century the most fearsome weapon available to humanity will be throwing big rocks at Earth. So I don't like the idea of placing asteroids from the belt in either Lunar or Earth orbit. The potential for disaster, either deliberate or through an accident, is to great. IMO it's simply to dangerous to do this. It makes more sense to go to the asteroid belt for mining purposes.

Here's an interesting book about current "space law" and how it might be changed to reflect an expanding period of space exploration & exploitation:

https://www.amazon.com/gp/product/08...22815a1cc0a830

One of the authors is Glen Reynolds who runs the Instapundit Blog and is a Professor of Law at UT. I thought it was a good read and anyone interested in this topic should check it out.

Here's an article linked to at Instapundit that is "space" based but also a bit risque:

http://www.smash.com/space-sex-needs-more-research/

Watch the short video embedded in the article as it's quite good. Bottom line is that this is a serious question, particularly for long space flights. Determining the impact of micro gravity & radiation on sexual activity and procreation will have to be done.

Maybe they need to contract a pron company to kick start this effort!

It's hard to not be impressed by SpaceX!

http://www.space.com/36852-spacex-la...satellite.html

Another successful launch of their "reusable" rocket and another satellite placed safely in orbit. Trump needs to follow Obama's lead here and make sure the path is clear for private company space exploration. It clearly works!

File this story under "if this doesn't blow your mind you're a rock" category:

http://nypost.com/2017/05/18/scienti...llel-universe/

In a nutshell these scientists are claiming:

Now a new study has stumbled upon an incredible possibility, that the ‘Cold Spot’ cannot be explained as a void and was not due to “line-of-sight” effects.

Instead, researchers at Durham University believe it could be the first evidence of the “multiverse.”

They believe a parallel universe could have smashed into ours affecting it in a way similar to a multiple vehicle pileup.

That impact was so incredible, according to this research, that it pushed energy out of a huge region of space resulting in the Cold Spot.

“Perhaps the most exciting explanation is that the Cold Spot was caused by a collision between our universe and another bubble universe, believe it or not,” said Professor Tom Shanks, an astronomer at Durham University and a co-author of the study.



I'm still thinking that huge "cold spots" like this one are the remnants of a ferocious war fought between two hyper advanced civilizations a billion years ago. But a "multiverse" explanation will work to!

Yea I know the attached is an "infomercial" for IntelSat EPIC communications satellites but clearly "space" will be critical to seeing the fourth Industrial revolution come to fruition:

http://spacenews.com/sponsored/industrial-revolution/

This is the key part:

Space is stepping up to the connectivity challenge posed by the fourth industrial revolution. One of the driving forces of this change has been the introduction of next-generation high-throughput satellite (HTS) systems, such as Intelsat’s EpicNG. HTS will enhance the end user experience much like the terrestrial move from dial-up to broadband access.

These HTS satellites provide far more throughput than existing wideband satellites, with increases in throughput of up to 400 percent. Intelsat EpicNG incorporates multiple smaller spot-beams with high frequency re-use. Performance on an EpicNG satellite is improved not only in bits per second per Hertz, but also in the aggregate MHz available and the geographic area covered. EpicNG complements Intelsat’s existing global widebeam coverage areas, providing satellite bandwidth anywhere on the globe.



Check out the embedded video to, it's pretty cool.

Hmm. It certainly a sensational explanation, but it sounds as if they they threw it out there just to get some press, not because it's the best scientific explanation - and very likely isn't.

On the other hand, maybe this is just as likely:

Cool video and who knows it may be right!

As for throwing the multiverse theory out to garner some press, absolutely that's what they did. That kind of headline is extreme nerd click bait if ever there was one.

Here's some great news for a Sunday morning:

http://www.dailywire.com/news/16643/...al-joseph-curl

It seems like all those satellites we parked in orbit and their constant emission of low frequency radio waves has attracted cosmic particles to envelope the earth and form a protective barrier against solar "weather".

This, scientists say, is potentially very good news, as we could use the barrier to protect Earth from extreme space weather resulting from events like coronal mass ejections—huge explosions on the sun, where plasmas and magnetic field are ejected from its corona, the outermost part of its atmosphere. These ejections can result in geomagnetic storms, which have the potential to knock out communication satellites and power grids.



If you're wondering what the good news is, this barrier could prevent another Carrington event from collapsing modern society by destroying our electronics based civilization:

Setting the stage for a trip to Mars is getting closer:

http://www.msn.com/en-ph/news/techno...ars/ar-BBBjSQk

What's cool about this idea is that if we can mine lunar ice to covert into rocket fuel and then place it into space to be picked up by ships heading to mars & beyond, you cut the cost of exploring the solar system by a whole lot!

The idea would go like this:


Depending on where the best ice reserves are, we might need to build several small robotic moon bases. Each one would mine ice, manufacture liquid propellant and transfer it to passing spacecraft. Our team developed plans to accomplish those tasks with three different types of rovers. Our plans also require a few small robotic shuttles to meet up with nearby deep-space mission vehicles in lunar orbit.

One rover, which we call the Prospector, would explore the moon and find ice-bearing locations. A second rover, the Constructor, would follow along behind, building a launch pad and packing down roadways to ease movements for the third rover type, the Miners, which actually collect the ice and deliver it to nearby storage tanks and an electrolysis processing plant that splits water into hydrogen and oxygen.

The Constructor would also build a landing pad where the small near-moon transport spacecraft we call Lunar Resupply Shuttles would arrive to collect fuel for delivery as newly launched spacecraft pass by the moon. The shuttles would burn moon-made fuel and would have advanced guidance and navigation systems to travel between lunar bases and their target spacecraft.

Jeff Bezos is talking about building a city on the Moon and he's dead serious:

https://www.geekwire.com/2017/jeff-b...e-origin-moon/

I've always thought the Moon would be the first place off earth that we would establish permanent settlements. The advantages versus space stations or Mars are considerable. Bezos even has a preferred location on the moon:

Bezos noted that the moon’s polar regions would be the best places to build a base, because some craters in those regions are thought to contain reserves of water ice that are shielded from sunlight. That ice could be converted into liquid water for drinking, hydrogen for fuel, and oxygen for breathable air.

Pretty lame attempt at trolling esp. I mean even a cursory read of the posts on this thread would show that the topics are all over the map. The only pattern is they are science related and most of them address an element of space exploration.

Amid all the sound & fury of politics in DC an important subcommittee hearing being led by Ted Cruz is not getting much play and it should be. It's addressing, among a number of items, whether we should stick to the 1960's era Space Use Treaty:

http://behindtheblack.com/behind-the...-space-treaty/

I think the author makes a number of excellent points about the foolishness of following a treaty on "Space Rights" signed in the 1960's.

The legal witnesses all advocated keeping the treaty. From their perspective, the treaty’s sixth article, which states that “The activities of non-governmental entities in outer space, including the moon and other celestial bodies, shall require authorization and continuing supervision by the appropriate State Party to the Treaty,” gave the U.S. the proper authority to set policy for its citizens that would sufficiently protect their property rights.

Yet, will it? As James Dunstan of the Mobius Legal Group noted, “I don’t think the Outer Space Treaty as it is written would allow for the United States to even recognize domestically [property rights]. … I think article 2 is pretty clear, we can’t domestically recognize property rights. We would have to go in and renegotiate that treaty.”

Furthermore, no one addressed the problem of conflicting property claims between different nations. What if two nations want the same specific piece of territory? As they say in the real estate business, “Location, location, location!” The Moon has only only two poles, and the places at those poles that would have either eternal light (for solar power) and eternal darkness (with ice available) are going to be limited. Everyone will want that real estate.

What if a U.S. private company sets up operations there and the Chinese moved in to push them off? Nothing in the Outer Space Treaty provides any protection to that company or its rights. In fact, article two of the treaty specifically forbids any nation from claiming sovereignty on any territory. Because no nation can control any territory legally, whatever regulations or protections it creates under article 6 to protect the rights of its citizens are made null and void by article 2, which states that no nation’s laws can supersede another’s on any territory in space.

The bottom line is that any policy the U.S. puts forth that does not include sovereignty to the territory that its citizens possess in outer space will not be worth the paper it is written on
.


The good news is that increased commercialization of space is spurring a renewed look at the legal implications of such development. The bad news is that the DC establishment seems reluctant to overturn precedent even when doing so is in the clear interests of the US. The swamp is big & deep.

Some more mind bending stuff about Dark Energy:

http://www.livescience.com/59283-why...elerating.html

Some background:

Scientists call the force that pushes the universe to expand a cosmological constant (though it isn't a "force" in the strict sense). This constant is the energy density of space itself. If it is greater than zero, then Einstein's equations of relativity, which describe the structure of space-time, imply an expanding universe. In the late 1990s, measurements of distant supernovas showed that the universe was accelerating, not just expanding. Cosmologists call the energy that drives that acceleration dark energy. Whatever dark energy is, it dissipates more slowly than matter or dark matter, and doesn't clump together the way either of them do under the influence of gravity.


The new insight:

"Every point in space is going through expansion and contraction," he said. "But it looks smooth just like a table looks smooth from far away."

The vacuum fluctuations, in Wang's formulation, are like children on a swing pumping their legs. Even though nobody is pushing them, they manage to impart extra energy on the swing, making the swing go up higher than it would otherwise. This phenomenon is called parametric resonance, which basically means that some piece of the system — the expansion and contraction, or the swinging of the child's legs — changes with time. In this case, the density of a very tiny portion of the universe is changing, Wang said.

Wow, now here's an unlikely entrant in the race to colonize Mars:

http://www.latimes.com/world/la-fg-u...531-story.html

The United Arab Emirates (UAE) is planning on building a city of 600,000 people on Mars by the year 2117! Now that's ambitious. And before you scoff these are the same folks who built a functioning indoor ski resort in the dessert so who knows.

File this story under amazing:

http://www.space.com/37000-solstice-...i-mission.html

Has there been a more successful deep space probe than Cassini? It arrived in Saturn orbit in 2004 and it's still sending us back breathtaking pictures. Well it's hit another milestone as we now have on record the entire seasonal cycle of Saturn. It has a much longer cycle than earth and the pictures in this article are stunning.

Here's an example of something that on the surface doesn't seem like such a big deal but when you think about it this may be the most important experiment going on in space right now:

http://www.space.com/37068-beam-infl...ear-space.html

A privately built inflatable space habitat has just passed its first year attached to the International Space Station. The habitat named BEAM for Bigelow Expandable Activity Module (what a name) passed it's one year test with flying colors. It showed that it could protect astronauts from micro meteorites & space debris.

Now it enters the critical phase of testing where it will be assessed for it's ability to shield astronauts from space radiation. This is the acid test for whether BEAM will be a breakthrough product for use in extended deep space exploration. Keep your fingers crossed!

History was made when SpaceX capsule Dragon became the first private space craft to make a REPEAT visit to the International Space Station (ISS). Also this was the first "repeat" visit of a spaceship to the ISS since 2011:

Water appears to be quite a ubiquitous compound in the solar system:

https://www.sciencedaily.com/release...0605085344.htm

By studying the valleys on Mars researchers were able to estimate that the amount of FLOWING, LIQUID water needed to carve these features was much greater than previously thought.

They also make another interesting observation:

But a large piece of the puzzle is missing, he added, because climate models have not been able to reproduce an early Mars climate sufficiently warm enough to promote an active hydrologic cycle.

"Mars is much farther way from the sun than Earth, and when the sun was younger, it was not as bright as it is today," Luo said. "So there's still a lot to work out in trying to reconcile the evidence for more water."


Maybe the sun was brighter than what they ASSUMED it was in the past or maybe brightness isn't the only vector for solar energy output or maybe we were traveling through a region of space that has fewer particles deflecting solar energy away from the planets or maybe Mars has experienced titling that reduced the amount of solar energy reaching it?

Bottom line is that climate models continue to fail both here on earth and on Mars.
