Juno arrives at Jupiter

Juno arrives at Jupiter

Postby John Galt » Tue Jul 05, 2016 8:12 am

Well, what a day. What an achievement.

After a five year journey from Earth, Juno the solar-powered spacecraft squeezed through a narrow band, skimming Jupiter’s surface, avoiding the worst of both its radiation belt and its dangerous dust rings.

It fired its main engine, slowing its velocity, and allowing it to get captured into Jupiter’s hefty orbit.

After it was complete, jubilant scientists fronted a press conference, and tore up a “contingency communication strategy” they said they prepared in case things went wrong.

“To know we can go to bed tonight not worrying about what is going to happen tomorrow, is just amazing,” said Diane Brown, a project manager from NASA’s Jet Propulsion Laboratory.

Scott Bolton, principle investigator of the Juno mission told his colleagues: “You’re the best team ever! We just did the hardest thing Nasa has ever done.”

Now the spacecraft will orbit the planet once every 53 days until October 14, when it will shift to a tighter 14-day orbit. And after about 20 months of learning everything it can about Jupiter’s interior and its atmosphere, it will eventually succumb to the harsh environment and plunge into the planet’s crushing centre.

But right now all that is ahead of us. We watch wide-eyed, eager to learn about the giant planet, and in doing so, learn more about how we all got here.

I know it was a difficult mission Mr. Bolton but I'm pretty sure that Apollo 13 was harder than this. so was the entire idea of going to the moon using a calculator for a central computer

that said, should be good once the images start rolling in

That stuff is amazing. We have learned more about the cosmos in the past few decades then we learned in our entire history. Same goes for exploring the ocean.

well in that regard, 100 years ago we were using pigeons to carry messages. juno on the other hand has the length of a basketball court and we made it go 93,000 mph. which is 25 miles a second. to put this in perspective, a 50 caliber fires a bullet at about half a mile a second.

in THAT regard, slowing the sucker down was extremely challenging for NASA, but they figured that out years ago, which is why i don't think that what mr. bolton said was correct.

Its a pretty interesting profile. 35 minute burn to drop into orbit? Wow. I wonder if they plan on rounding the orbit out later on, or if they play on staying that crazy elliptical for the whole mission. I get that they want to stay out of the radiation, but the polar orbit should be fine quite a lot closer than what they're at now...
