Plutonium 238 production is crucial for the future of deep space exploration.  NASA's supply of the isotope was dwindling, given that it was made during the Cold War, and not much made since.  In 2012 production of Plutonium began once more, but only amounted to a trickle.  Now, with help of new robotic systems, production has ramped up to 8 times amount coming out of Oak Ridge TN.

Weren't those people suppose to have started new production of isotope??

They did, but it was only about an ounce and a half per year.  This article is about how they are going ramp up production by a value of 8 times.

Heh... Once we knew plants could grow in zero-g, it wasn't really much of a question if they could grow in something between that an 1g...

Dang, they got there ahead of Eu:Cropis (which is currently spinning up to provide lunar gravity in LEO for the tomatoes it will grow - but at least it'll then afterwards be the first to grow stuff at Martian gravity in half a year).

I suspect they're also testing local conditions like radiation and whatnot.  Obviously it's got some sort of CO2 supply to keep the plant alive, but I can't imagine a little rover like that is going to have much in the way of radiation and thermal shielding; can the cotton plant grow in that condition is important.  Especially if we ever intend to have farms up there...

Wonder what the specifics of the environment they're growing it in is, how long it's expected to live, etc.

Hydroponics underground would definitely work... not really sure what they're trying to prove honestly.

Nah, the biological experiment capsule on the lander is way too small for that (it's on the lander platform, not on the rover). They'll probably crossreference with LND though, the radiation sensor suite contributed by the German Space Agency on the lander.

The lander basically only carries LND, the biological experiment capsule and a radio frequency spectrum analyzer mostly to detect solar storm emissions (being shielded from interference from Earth where it is; there's a Dutch-Space-Agency-contributed radio astronomy instrument for similar reasons on Queqiao, the relay satellite).

Hydroponics underground would definitely work... not really sure what they're trying to prove honestly.
Plant growth is rather sensitive to gravity actually, especially plants that grow "bidirectional" (roots and stem).

There are also issues with testing certain automatisms in habitat environments, for hydroponics the water is an issue in particular; less the cycling, more the fact that you can't test that kinda thing anywhere where NASA gets involved because they want prohibitive triple encapsulation on any water-related experiment going to ISS (hence why e.g. Eu:Cropis tests this on a fully separate satellite, which has been waiting for SpaceX to launch it for two years now).

I wonder how long experiment will go?  Radiation is a factor, also how much water the vehicle is carrying to keep the plants alive.

This is the dark side of the moon right? Their own light source keep the plants alive, not natural sunlight, right?

The "dark" side of the moon is anything but dark.  The best term to use is "far" side of the moon.

Inside the lander it isn't a natural light source.  But there would be plenty of light outside.  The main difference being that it isn't a 24 hour light cycle, lunar light goes on for days.  Same for lunar night.

Total lunar eclipse in North & South America this weekend!
https://www.space.com/42830-supermoon-blood-moon-total-lunar-eclipse-2019.html



No really, it's a major eclipse, totality will last just over a full hour. There's schedules and maps for where it's visible from, but basically if you're in the western hemisphere and have clear skies, you're gonna get a nice view.

And it's dead. To be fair, it lasted longer on the moon than it would have in my house.

Xie said temperatures inside the biosphere had grown too erratic and reached extremes that would likely kill all life, including the seeds and eggs.

That's the kind of environmental concerns I was wondering about.  The moon is pretty damn harsh when it comes to temperature; clearly whatever materials they were using as a lunar greenhouse didn't cut it.  Sometimes you can only find out by trying in situ.

A similar thing used to occur in my house until I conceded all temperature controls to my wife.

The experiment is actually about whenever the enclosed biosphere (containing cotton and potato seeds, yeast and fruit fly eggs.) is sustainable on its own.

https://www.bbc.com/news/world-asia-china-46873526?ocid=socialflow_twitter

Quote
The lunar mini biosphere experiment on the Chang'e-4 lander is designed to test photosynthesis and respiration - processes in living organisms that result in the production of energy. The whole experiment is contained within an 18cm tall, 3kg canister that was designed by 28 Chinese universities.

The organisms inside have a supply of air, water and nutrients to help them grow. But one of the challenges, say Chinese scientists, is to keep the temperature favourable for growth when conditions on the Moon swing wildly between -173C and 100C or more.

They also have to control the humidity and nutrients.

Currently in development is a probe called Lucy, set to launch in 2021  Lucy's mission will be to travel to 6 different asteroids.  1 asteroid will be in the main asteroid belt, the other 5 are asteroids in Jupiter's Trojans.  Using the extremely successful ion engine (as seen on the Dawn orbiter that brought us to Vesta and Ceres), Lucy represents the next generation in space exploration with a complex mission.

As I understand it, it doesn't rule out planet 9, it just shows that planet 9 isn't required.

Personally I think the idea that we had another gas giant in the system at start that got ejected early is more interesting. That's a ready-made candidate for planet 9. :)

We may not find out in our light time.  If we do, that's great. I say leave couple mysteries for the next generation to enjoy.  ;)

With shutdown for the US temporarily ended. I hope first of the crewed commercially launched vehicles will get strut its stuff next month. I imagine NASA personnel got messed up good this shutdown.

Itokawa looked about as rocky from similar distances.

Part of that is visual bias. Bennu - and Itokawa - are relatively small at only a few hundred meters, so resolution at similar image size is of course better.

I can't wait for the really hi res stuff to come in from New Horizons.  With how close it passed and remembering the treats we got of Pluto a couple of months after flyby, we might be in for some great visuals like this from Bennu.
