Putin ordered a cosmonaut to make the hole so he could blame the USA

Now, in rare cases, fluid shifts — i.e., when bodily fluids move into different compartments due to changes in pressure — may actually result in hard-ons harder than you’ve ever experienced on Earth. “A couple of times, I would wake up from sleep periods and I had a boner that I could have drilled through kryptonite,” astronaut Mike Mullane told Men’s Health.

Maybe Putin will do a Porkys and inspect the guys for a drill sized pecker

Going back to "What constitutes a planet?" topic, would two Jupiter sized objects which orbit around each other not be considered planets because they wouldn't fulfill the "gravitationally clears their orbit" criteria? If so that seems kind of nutty to me.

The IAU definition only applies inside the Solar System, so this conundrum isn't actually relevant to the question of a binary-Jupiter system. I don't think I would call them planets since they aren't orbiting a star though.

What?? It only applies to our solar system? Not any solar system? If each solar system has its own definition of a planet then the definition of a planet is almost meaningless.

I didn't explicitly state it but my intention was that the dual Jupiters were orbiting around each other and also orbiting around a star. Also I believe rogue planets are a thing.

 

[Berzerker]

Thats a good question, I'd expect it would depend on which of the two had more mass. Like, if Saturn and Jupiter orbited each other Saturn might be considered Jupiter's moon... maybe. If they had comparable masses I'd think both qualify as planets. I believe its a rogue planet that has tilted our solar system, the '9th' planet.

Take that up with the IAU, I wondered about it too.

Afaik rogue planets are generally considered to have been ejected from solar systems at some point. I'm not sure that current mainstream theories of solar system formation would support the outcome of two jupiter-size bodies orbiting each other and a star. But otoh it seems like every other new exoplanet discovery is calling all existing solar system formation theory into question so idk.

pluto will become a planet once again , because .

is as good as it's not , because .

They'd be binary planets. Earth and the Moon are very nearly binary planets because the center of gravity between them is removed from the Earth's geographical center due to how large the moon is. Really the Earth/Moon system is kind of a freakish thing because most moons are not nearly as large relative to their primary as our Earth is. Pluto and Charon both orbit a spot outside of Pluto for the same reason and if Pluto was considered a planet we'd likely have to consider Charon to be one as well and they'd be a binary planet system.

Binary planets would still clear their mutual orbit about the sun, which is a different orbit from the one they have about each other. Therefore they'd still be planets.

I read a report stating that the theory that American astronauts sabotaged the Soyuz capsule has picked up traction in Russian media which isn't that surprising really. What is surprising is the logic behind it which has something to do with America not being able to afford future Soyuz flights (at about $90 million a seat) or something along those stupid lines. Really that's peak projecting - it's much more likely that Russia won't be able to continue a manned space program if it wasn't for the highly-inflated payments they get from NASA for rides on the Soyuz. We'll find out in a year or so when Boeing and SpaceX begin launching astronauts and NASA stops buying Soyuz seats.

It should be noted, that the center of gravity is still located inside the Earth 100% of the time. Interestingly, the Solar System barycenter moves out of the Sun pretty frequently due to the mass and distance of Jupiter.

I did google search in Russian, it looks like aside of previous article in Kommersant, even tabloids don't consider this version seriously. If report you read contains references to specific Russian media I can read it, but all I found for today is government officials labeling sabotage version as a crazy conspiracy.

Mars P.D. will have to deal with new blood-spatter patterns, different body decay rates, and space-suit sabotage—and they won’t be able to fire guns indoors.

SpaceX released their new plans for the BFR/BFS system and announced that a Japanese billionaire had bought all 9 seats available on a launch to go around the moon. He will be taking 8 artists with him which is really cool.

Rather than summarize the article and the live-stream event, I can answer any questions you guys might have.


Also apparently Trump has proposed increasing the budget for the office of NASA responsible for tracking nearth-earth asteroids from $50m to $160m or something like that. Neat.
Though if we do create a space force, asteroid defense should be shifted to them.

If there is a Asteroid defense corps, it should be headed by Bruce Willis.

It will be like that episode of South Park where they had Kurt Russell head up the team that entered the imagination portal "because you were in that movie one time that was kind of like this"

Hayabusa-2: Japan hopes for historic asteroid landing

Japan's space agency (JAXA) believes it has successfully landed two robotic explorers on the surface of an asteroid, making history.

"We don't have confirmation yet, but we are very, very hopeful," project manager Yuichi Tsuda said.

On Friday, the Hayabusa-2 spacecraft despatched a pair of "rovers" to the 1km-wide space rock known as Ryugu.

Rover 1A and Rover 1B will hop around in Ryugu's low gravity, capturing temperatures and images of the surface.

Hayabusa-2 reached the Ryugu asteroid in June this year after a three-and-a-half-year journey.

Officials hope to confirm a successful landing in a day or two, when the spaceship sends data from the rovers to Earth.

Hayabusa-2: Japan's rovers send pictures from asteroid

Japan's space agency (JAXA) has made history by successfully landing two robotic explorers on the surface of an asteroid.

The two small "rovers", which were despatched from the Hayabusa-2 spacecraft on Friday, will move around the 1km-wide space rock known as Ryugu.

The asteroid's low gravity means they can hop across it, capturing temperatures and images of the surface.

"Both rovers are in good condition," the agency confirmed on Saturday.
