The Space Thread

so, boeing is throwing money at mars aye? history repeats itself. didn't th picts just get back from mars?

Awsome HD footage from JAXA's Kaguya probe of Earth rising over the Moon:

 What's with the lens !! Aren't the japanese famous for making decent cameras. Surely even though the sun is coming from the side they could have gotten a better sourced image than this. Also, i didn't realise that the moon was so bumpy.

"Will astronauts heading to Mars be putting their own brain health at risk? A new study out of the University of California, Irvine found that exposure to highly energetic charged particles similar to those that hit astronauts on long space trips led to brain damage in test rodents. The damage included dementia and other cognitive impairments."

Billion dollar spacecraft, 4 dollar camera.

new horizons next target is a kuiper belt object that's redder than pluto called MU69

Makes me want to read the KSR's mars books again (though the systems involved in that seem quite quaint compared to this vision).

and check KSR consider musk's vision quaint and a "20s science fiction cliche"

not surprising that, science fiction writers are often technological curmudgeons when it comes to the real world for some reason. musk has actually built spaceships though, so I think he may have a better idea about the whole thing than a guy with a PhD in english literature.

i somewhat agree. although, i believe it was arthur c clarke who, when asked how he came up with such far out stories his answer was "i've already been there"

inside the ring of uranus, more precisely

So, what's the deal with the Juno mission? Kind of thought we'd have a bunch of amazing pictures of Jupiter by now. I know there are higher priorities for astronomers than  pictures but still, just wondering.

because of the lens you only get good resolution at the perijove. sometime this week is the third perijove. for the first one the camera wasn't talking pictures because it was doing a rocket maneuver to enter orbit. the second perijove gave us like 6 pictures. this one i don't think they're doing pictures because they're doing a rocket maneuver to shorten the orbit. after this, orbits will be 14 days instead of 70 something days.

extraterrestrial megastructure targeted by SETI

exciting. the propellantless microwave propulsion theory seems to be surviving close scrutiny. next we need to demonstrate the theory works in practice. if that happens, that's nuts.

dark matter effect could actually be caused by spheres of primordial black holes surrounding all galaxies

interesting article. key point is that, apparently, the cosmic infrared background matches up with the cosmic xray background, and the only thing that radiates across that spectrum is black holes.

cool simulation of merging black holes using the interstellar render code in there too

The JunoCam imager on NASA’s Juno spacecraft snapped this shot of Jupiter’s northern latitudes on Dec. 11, 2016 at 8:47 a.m. PST (11:47 a.m. EST), as the spacecraft performed a close flyby of the gas giant planet. The spacecraft was at an altitude of 10,300 miles (16,600 kilometers) above Jupiter’s cloud tops
