From the description on the page: In this interactive visualization, you can ride along with the Juno spacecraft in real-time at any time during the entire mission. For example, watch the arrival at Jupiter on the 4th of July, 2016, or see Juno use Earth’s gravity as a slingshot to pick up speed, or just learn about the science of Jupiter and about the spacecraft itself. You can even turn on and off the magnetic field, aurorae, and the radiation belt, all in 3D! All of this and more is waiting to be explored.

I previously submitted this earlier today. Here's the link for YouTube: https://www.youtube.com/watch?v=UdmHHpAsMVw It's been really great being able to stream in HD on my Chromecast :)

Thanks! I really didn't want to go enable flash

This cracks me up! Jupiter's moons were named after Jupiter's mistresses. Juno was his wife..

> Juno was his wife..

Was...? Now that's some dedicated faith, still practising Ancient Roman religions!

Was is fine. Those gods have passed on to myth and legend.

So if I say, "Darth Vader was Luke's father," do you have to remind me that Star Wars isn't real?

The only real error is the parent comment not using literary present tense, but that is being pedantic at best.

Some people still do, well, a reconstructed version. Search for Religio Romana.

"The god Jupiter drew a veil of clouds around himself to hide his mischief, but his wife, the goddess Juno, was able to peer through the clouds and see Jupiter's true nature."

Well, Ganymede was a guy, and the relationship between him and Zeus is a matter of some debate (inasmuch as mythical stories like this could be debated). Xenophon maintained that the relationship between Zeus and Ganymede was platonic.

And it began successfully its first orbit. Now that it has completed its 1.8-billion-mile journey, the solar-powered craft is set to cruise around Jupiter 37 times over a period of 20 months. Juno will collect information about the planet’s magnetic field, composition and internal structure.

Cool!

I did note that everybody in their control room is wearing identical grey polos... guess somebody really doesn't want a repeat of the shirt incident.

Shirt diversity is at an all time low.

It's been a traditional at JPL (and other NASA centers) to wear matching polos for quite some time now, at least years, before the Rosetta landing. Not saying that NASA is better than ESA as far as women or PR goes, but this wasn't a reactionary move.

Let me save everyone else a google query: http://nypost.com/2014/11/17/the-outrage-machine-insande-ado...

That shirt is 80s AF \m/ I can see how it might not fly at work though, at least not on a big PR day.

Wow, just noticed that NYP is some sort of hardcore Trump fan vent hole. My apologies. I can't believe they have the nerve to call the shirt "tasteless", though!

"Over the last few days, we have learned that mankind can chase down a comet speeding through space at 34,000 mph, but resisting the outrage machine, kicked into high gear over a trifle, is completely beyond its powers."

Arg I hate being at work at this time. My lunch breaks about to finish, so at least I can catch up in a few hours.

The burn has started according to the tweets though! Good luck Juno and NASA team!

I had no idea. I was listening to this on the radio this morning. I was not sure if they were narrating a science fiction work like a movie or if it was real news.

Stupid question in general. Given how long it takes for a spacecraft's signal to reach earth, I suppose we can use the time difference to calculate the distance from a spacecraft such as New Horizon to earth. But how do we know its exact location at any given moment? What are the equivalence of GPS and cell towers in space?

This story partially addresses your question. It doesn't have enough details.

Because so many constraints are needed (position, pose, velocity) there is no simple single answer. Here is a summary -- https://solarsystem.nasa.gov/basics/bsf13-1.php

Skip down to "Navigation Data Aquisition"

Don't have all the answers, but last night, on the webcast, they were explaining that the spacecraft uses the stars for navigation [1].

In addition, instead of wasting valuable power for radio transmission, they send a simple tone back to Earth [2]. With that, they can determine if various events were successful (tones are sent at specific event times), also calculate the changes in speed/rotation using doppler shifts from the "tones" [3] (validating the engine fired, current spin, etc)

There is an optical camera on board, did it send any close up jupiter pictures this first go-around?

According to the press conference, all non essential instruments were turned off 5 days ago.

Right now, all the instruments are off during this first orbital insertion. The next close pass (Perijove 1), where the closest pictures will be taken, is around late August.

View lots more details here: http://www.planetary.org/blogs/emily-lakdawalla/2016/0609060...

NASA is definitely hitting its stride on the PR side, considering the date. Good for them.

I didn't realize Juno would have such a large capture orbit. 54 days and change to complete one pass. Makes sense though. They way they are skirting the Ionian radiation torus is pretty slick.

Remember that they are choosing an orbit that allows Juno to keep facing the sun as well.

Watched The Martian in the morning and then closed off the day watching NASA insert a spacecraft into Jupiter orbit. I'm on a NASA/JPL high right now!

Thought all these posts were about classic Roland polyphonic synthesizers for a second...
