Deep Space and Interplanetary Exploration - Houston, we are go for launch!

[Daryk]

The article itself provides explanations for that, among them:

“That doesn't mean that all GRBs do not produce them,” Blanchard added...

There's more toward the end too... I don't think it disproves the theory about heavier elements.

[ANS Kamas P81]

Isn't neutron star collisions the current go-to model for heavy element production?

[rebs]

Neutron Stars too, yes.  But I had always read that supernovae in general produce elements heavier than iron. 

I would imagine that the really heavy elements are probably more abundant in neutron star collisions, or white dwarf collisions.

[Maingunnery]

Random thought: would that also mean that the quantities of heavy elements could vary a lot between star systems?

[Daryk]

Certainly... the universe isn't homogeneous...

Looks like scientist have figured out how Pluto got it's heart shape feature on the planet.

It appears in ancient time a object size of Switzerland collided with Pluto, creating the Sputnik Planitia & Tombaugh Regio regions, aka each sides of the heart.

Unfortunately, the report suggests that because way things turned out and the impact on the region would thinned crust of the planet, there is most likely no subsurface ocean.

Report was posted on phys.org.

Excellent follow up on Pluto.  At that distance, a small object maintaining a subsurface body of liquid water all this time was questionable.  Not foregone by any means, because there's so much for us to learn when we aren't getting in our own way by assuming we have things figured out.  But questionable.

And now we know.  Or at least we are pretty sure we know.

NASA has decided that the cost to return Martian samples to Earth is too high.  And waiting until 2040 is far too long.  So an overhaul of the sample return mission has been called.  Let's see how that goes.

Any bets that the price goes up and gets blamed on inflation?

[Daryk]

The price will certainly go up, and inflation will be among the reasons... ::)

[Prospernia]

After seeing Species, I'm glad they're not returning samples from Mars.

Looks like further study has revealed that the so-called "Ice Giants", Ouranos and Neptune, contain a lot less water than previously thought.

As mentioned in another thread, IIRC, "All models are wrong. Some models are useful."

It's generally agreed the ice giants didn't form in their current places; would have taken unfeasibly long for that to happen. How that impacts the ice vs methane mix (H2O having similar molecular weight as CH4, but greater adhesion) needs consideration.

Check out this amazing image of Phobos!  I’ll attach the file….

[Wrangler]

That's a big bump on that moon.

[rebs]

That crater looks catastrophically big.  Compare it to Tethys or Mimas prominent impacts.

[rebs]

While we're on the subject of massive impact scars, my favorites.

Caloris on Mercury.  If the impactor had been any bigger, perhaps it would have destroyed Mercury.

And Valhalla on Callisto.  Just look at the epic rings that frame it, and how extensive they are, one after another.

That's an amazing photo of Phobos!  What was the source? :)

[Wrangler]

Good News The Dragonfly quadcopper probe was approved for the Titan mission!  Won't get there till 2034, but it's something that was on verge being cut!  Hope it gets to the finish line!

[rebs]

That's an amazing photo of Phobos!  What was the source? :)

Source is NASA.  It's actually far older than I thought, the net is giving it a date of 2013.

This is the first I saw it.

I saw that, too.  But the article was cheesy, this one you posted is better.

Thanks for the citation! :)

That's no Danais Dropship...

Honestly, I had little trouble finding the original announcement. It could have been buried.

It looks like a texture map for a video-game.

And Doom, '93, got Phobos wrong; it doesn't look like a lush-paradise.

[Daryk]

That's... not what I remember of Doom back in '93? ???

[rebs]

Phobos is an asteroid that got caught.  We can't be expecting much of it, or any disappointment is on us.

[rebs]

2013 I was still taking care of my grandma before she died, so I missed a lot of things going on.  My only outlet at that time was getting caught back up on BT after a break between 1997 and 2012 when I googled it and found out that it was still alive and doing well.

Link to an article with a new video detailing all the Martian flights of the Ingenuity drone.

Complete with atmospheric-scattering and you can walk outside on Phobos!


And

[Daryk]

Back then, I thought Doom Guy was wearing a space helmet? ???

How many of you have fought the good fight as Star Captain Samus Aran, a female Elemental Warrior, who fights the drezga Dark Caste and their inhuman Gencaste allies on the Deep Periphery planet of Zebes? Jump Jet attacks, rolling and crouching while Lasing and firing deadly Missile barrages. All since 3025! (Of course, it's 1986!)



(I figured ya'll needed a good chuckle?  )
