Our Mission Animations playlist will give a feel for what Juno’s orbit is like — especially? the video titled, “Juno and Jupiter’s radiation belts.” We thread the needle between the planet and its innermost radiation belt, but over the course of the mission Jupiter’s oblateness causes the orbit to shift (see “Juno Jupiter orbit animation”) so that Juno passes increasingly into the more intense parts of the radiation belts. We get most of our radiation dose in the latter half of the mission.

Thx for answer. Why not orbit between Jupiter’s first radiation belt & the surface? Like the? ISS & other satellites do with Earth to avoid the radiation belt?

Juno is designed to complete its mission in about 15 months on orbit. Jupiter’s intense radiation limits the lifetime of a spacecraft that dives in as close as we must, passing more deeply through its radiation belts as the mission progresses. Because of this, there’s no way to keep Juno on orbit for years, so the mission is designed to end in a controlled way that prevents the possibility of contaminating the moon Europa, which could have conditions suitable for? living things.

Check out NASA’s Eyes on the Solar System. It’s a 3D interactive? solar system browser. Not only will you be able to see the planets’ positions, but also their moons, many asteroids and comets, and a large number of spacecraft. (Sorry Odin7thor, we must have missed your question amid the activity surrounding Juno’s launch!)

The outlook is improving. For the past several years, Congress has provided funds to NASA to support the Department of Energy (DOE) restart of domestic production of plutonium-238 for civil space exploration. DOE is nearing the end of a technology demonstration effort to prove out processes that will be used for Pu-238 production. DOE plans to begin producing Pu-238 at a? low rate next year (2014), and expects to achieve the full Pu-238 production rate in 2018. [See also rps.nasa.gov.]

Thank you for your response, could you tell me if the current shortage and long lead time of? Pu238 being sufficiently addressed now, or is the shortage likely to continue affecting future missions where a RTG/RPS would be necessary?
NASAJuno
October 23, 2013 at 11:53 pm
An RPS could have simplified some of the operational requirements for the mission, but Juno can fully achieve its science goals using a solar power system. As you’re well aware, some other missions to Jupiter and the outer planets might be enabled or? significantly enhanced by the use of RPS.

October 24, 2013 at 12:12 am
The Juno mission proposal team elected to use a solar power system for Juno when they proposed to NASA to conduct the mission. The team leaders made this technical choice? because no radioisotope power system (or RPS) was immediately available in this timeframe (2004), and the team decided that it would be more prudent from a programmatic and schedule standpoint for Juno to use solar power.

I don’t understand why NASA didn’t use a RTG power source on Juno? look at Cassini, its been in space since 97 and at the supposed end of its current mission? in 2017 it’ll still have over 300 W of power available from its RTG’s.
I really hope Juno isn’t using solar power to just to appease the anti-nuclear lobby.

We’re working on that very question. For observers in the U.S. the spacecraft might be visible with a telescope the night after the flyby, but it will be quite faint. It is possible that observers in South Africa and eastern India might be able to catch a view with a telescope or binoculars during the flyby — we plan to post info on the NASA website? by sometime this summer. Hopefully someone will catch a photo of Juno streaking across the stars and share it!

In my 15 or so years on the internet, demonchizer’s comment ranks as the most lacking in subject matter understanding, yet juxtaposed and BLINDED by such self-confidence that he DOES know something, only to embarrassingly fall FAR and pancake into the concrete. The TV dinner & trailer bit has made me question, “By acting like the stereotype, was this his way of making fun of rednecks?” Or has a new level of ignorance has been reached?
