NASA's Juno spacecraft is opening its eyes to prepare for its first good look at Jupiter.
Juno's nine science instruments were off when the probe entered orbit around the solar system's largest planet Monday (July 4), to reduce complications during that night's make-or-break orbit-insertion engine burn.
The mission team powered up five of those instruments Wednesday (July 6) and plans to turn on the other four before the end of the month, NASA officials said. So Juno should be ready to gather some science data when Juno makes its next close pass by the huge planet on Aug. 27. (The probe is currently in a 53-day orbit around Jupiter.)
"Next time around, we will have our eyes and ears open," Juno principal investigator Scott Bolton, of the Southwest Research Institute in San Antonio, said in a statement today (July 8). "You can expect us to release some information about our findings around Sept. 1."

They are very tiny, which is probably why these dancing, usually colorful spiders had not been discovered until now.
This is not a video of the newest spiders but it is made by the discoverer.

I wish I could do maths.

It also shows up on the skin of people who have been struck by lightning or electrocuted.
What's updog
I love this stuff.
Old school OG spacecraft = 85 million circuit breakers.
A few generations later, in the digital age = 75 million circuit breakers and about 10 screens.
Now = 4 touchpanels. Go fuck yourself.
holy fuck this is so cool
do you need to do something to the wood (or get a specific type of wood) to make this happen?
but on Monday I regain access to a high-voltage power supply and a bunch of leads, and I'm sure I can drum up some wood from somewhere, so I'm going to try it
The couple of instructables and tutorials I've found say to coat the wood in a mixture of water and baking soda because the wood won't conduct the electricity very well on it's own and you want it traveling over the surface.
They also use about 2000 volts, so, you know be careful.

last week when you were Superman because the hot wax didn't hurt that much we thought it was cute, but you are ruining the mood we are going for here
bofa deeze nuts fucker
on the other hand I get to start some new research stuff, although working with ChemE's on batteries/catalysts stuff, or working with lasers on materials, or working with microwave catalysis are all cool sounding and difficult to choose between

On the one hand, a major breakthrough in battery technology will make the internal combustion engine look like the Zip Disk in terms of historical impact. On the other hand, a true scientist will always err on the side of lasers. On the third hand, that third hand was probably caused by whatever the fuck microwave catalysis is.
Which means you should go with the one that will give you superpowers. Always.

The battery one is the more practical one as a lot of folks are working to improve battery tech, and I'm sure I can find an industry job with either a battery company, or maybe even a larger tech company like IBM or so
The microwave one is neat cause you take transitional metals / some rare earth and react them with organic linker compounds in a microwave and hope it doesnt blow up (the vessel they are mixed into is sometimes referred to as a bomb ha). However the reasoning for doing this is to create catalysts much more efficiently and quickly. I've done this research in my undergrad and we made stuff in 8 minutes that traditionally would take 24 hours or so.

a group of otters on land is a romp
buffalos is an obstinancy
The plan is to send robots to the south pole of the Moon on the side counter to Earth to both increase the amount of solar activity while reducing the amount of Radio/Satelite/EM traffic (because they also want to install radio telescopes nearby). The first wave of robots will collect and prepare regolith for use as a building material.
Then they will send inflatable habitats and the D-Shape 3D printer.
A D-Shape printer is capable of printing out a small building out of sand, one layer at a time. What it will be used for is building a regolith structure which will house the inflatable habitat.
As a test they've already printed structures from a lunar regolith analog, including a 1.5 ton block of construction material. The plan is for a hollow, closed-cell design similar to honeycomb material, though this is covered over with a solid layer in all renderings of the final design.
NASA wants to try and get in on this, though their budget is tied up in Mars and the Asteroid Redirect Mission Just a reminder that NASA is still on track to pluck a boulder from near-earth orbit and place it in orbit around the moon, maybe giving the moon it's own temporary, upstart satellite while NASA tests out various procedures including mining.

I am doing some catalysis research right now before leaving for grad school! It's interesting science but man I don't get super enthused by chemistry. Condensed matter physics though, woah boy. What kinda lasers / materials / characterizations are we talking about here?
huh
it will be interesting to see if those work out in practice
While I've been really hopeful for that design, I don't think it's held up well to practical application. In areas where there is a surplus of straight road with no commercial traffic, it's pretty great, but the design just wouldn't work on American or European roads.
I really want to see them address some of the issues because I think that if you can make a mass transit option that can share the space without needing to build much more infrastructure, you'll be golden, but they haven't done much iteration on the design in the years since it's unveiling that will help it reach a larger area.

Among many other things, this means we could finally have feasible, precise BCI. What a time to be alive!
