NASA's Juno mission to the gas giant Jupiter has reached its halfway mark and has revealed new views of cyclones at the poles. The BBC reports: As it orbits the planet every 53 days - Juno performs a science-gathering dive, speeding from pole to pole. Its sensors take measurements of the composition of the planet, in an effort to decipher how the largest world in our Solar System formed. Mapping the magnetic and gravity fields should also expose Jupiter's structure.

But images from JunoCam -- a camera that was intended to capture images that could be shared with the public -- has already given us some surprising insights. "When we made our first pass over the poles, we knew we were seeing a territory on Jupiter we had never seen before," said Dr Candice Hansen, from the Planetary Science Institute in Arizona. "What we did not expect was that we would see these orderly polygons of cyclones; huge storms - twice the size of Texas."

NASA's Juno spacecraft has sent back the first photos from its close flyby over Jupiter's famous Great Red Spot. These images offer the closest ever view of the massive storm. The Verge reports: Juno has been orbiting Jupiter for a little over a year on a mission to study the planet's interior, atmosphere, and magnetosphere. Its elliptical orbit around the planet takes the probe close to the surface for a few hours every 53 days. These are called perijove passes -- and on July 10th, Juno completed its seventh. A little after its closest approach, Juno's camera, JunoCam, snapped a few shots of the storm from about 5,000 miles above. Typically, a team of NASA scientists chooses which images a spacecraft collects on its path around a planet. But with Juno, NASA's opened up the process to the public: space fans can weigh in on the photos JunoCam shoots by ranking their favorite points of interest. After the photos are taken, NASA releases the raw images for the public to process. People can crop them, assemble them into collages, and change or enhance the colors. The results are mesmerizing. You can view even more photos here.

Joe Palca reports via NPR: NASA's Juno spacecraft has spotted giant cyclones swirling at Jupiter's north and south poles. That's just one of the unexpected and puzzling findings being reported by the Juno science team. Juno arrived at Jupiter last summer. It's the first spacecraft to get a close-up look at the planet's poles. It's in an orbit that takes it skimming close to the cloud tops of the gas giant once every 53 days. After each close pass, the spacecraft sends a trove of data back to Earth. Ultimately, scientists will want to understand how these cyclones change over time and whether they form differently in the north and south poles. Another puzzle that Juno is supposed to help solve is whether Jupiter, a gas giant, has a solid core. Another surprise from Juno is the concentration of ammonia in Jupiter's atmosphere. Scientists thought ammonia was most likely distributed evenly throughout the atmosphere. The data show there's more ammonia near the equator than there is at other latitudes.

An anonymous reader writes "To attract media and Congressional attention to the deep NASA planetary exploration cuts proposed to take place October 1, and the need to restore the planetary budget to present or higher levels, a National Planetary Exploration Car Wash and Bake Sale is being planned for June 9th. Organizations already involved include planetary groups at many universities, research institutions, and Moon Express (Google Lunar X Prize)."

coondoggie writes "NASA shot its 4-ton Juno spacecraft into the cosmos today with the ultimate goal of learning everything we can about the largest planet in our solar system, Jupiter. Juno, once described as a flying armored tank, will take five years to reach its destination, slated to arrive at Jupiter in August 2016." NASA has an explanation of the steps involved in getting Juno through the launch, and an animated film explaining the mission. The mission website has streaming video of Juno's progress, and NASA's press kit explains the goals and the spacecraft in detail (PDF).

dj writes "NASA has designed a mission to map the boundary of the solar system. The mission is called IBEX (Interstellar Boundary Explorer) and it is ready to launch. The data collected by IBEX will allow scientists to understand the interaction between our Sun and the galaxy for the first time. Understanding this interaction will help us protect future astronauts from the danger of galactic cosmic rays." The IBEX Launch Blog will go active "about 2 hours before launch scheduled for 1:48 p.m. EDT," and the Southwest Research Institute will be running webcasts of the event. The IBEX fact sheet provides more details about the mission (PDF). IBEX will reach space via a Pegasus rocket launched from an L-1011 "Stargazer" carrier plane. You can see the launch countdown schedule at NASA's site.

Dr. Zowie writes "NASA's announcement last week of Sedna's discovery reignited the debate over whether Pluto is a planet. Dr. Alan Stern a noted planetary scientist and leader of the New Horizons mission to Pluto, pours on some gasoline with this article in which he skewers the various arguments against Pluto-as-planet. Choice quotes include 'You wouldn't deny a chihauhau a place among dogs because it is too small,' and 'if your brain was so completely full of names of people that it just couldn't take any more, would anyone new who you met after that, therefore not be a person?'"

jonerik writes: "No, not those Vulcans. The BBC has this article on the Southwest Research Institute's (SwRI) search for the Vulcanoids, a belt of perhaps a few hundred small asteroids (perhaps between one and 25 kilometers in diameter) theorized to exist inside of Mercury's orbit around the sun. Because of their closeness to the sun and small size, the asteroids - if they exist - would be hard to observe from the ground. To that end, a NASA F/A-18 is being used to conduct a search 'of the twilight sky near the Sun that is far darker and clearer than can be obtained from the ground,' says Dr. Dan Durda of SwRI. According to the article, 'The camera used in the latest search...is trained on the region of space close to the Sun after the star has dipped below the Earth's horizon. The camera grabs twilight images at a rate of 60 frames a second.' The researchers hope to have a better idea of whether or not the Vulcanoids exist in another month or two."

SEWilco writes: "This Nando/AP article points out that there's a discussion under way of how to proceed when an Earth-impacting asteroid is discovered. The focus is the proposal "The Comet/Asteroid Impact Hazard: A Systems Approach" (Chapman, Durda, Gold) which has been circulating for several months. It's a summary of what is known, what is undecided, and what needs to be done to prepare. I do note that the discussion is assuming that all of the human population remains on Earth, except for the possibility of off-planet planetary defense facilities." I thought we were well-prepared for this already, thanks to the flurry of asteroid movies of a few summers ago. We send Bruce Willis, or possibly William J. Clinton, with a handpicked suicide crew equipped with drills and nukes, right?

Every once in a while NASA does something amazing. Today they took a probe that was just supposed to orbit a rock the size of Manhattan, guided it down to the surface, reoriented the dish, and sent back a hello from ground zero. The NEAR Shoemaker mission site and its mirror are a little busy at the moment, but CNN's coverage is good, with simulated video, and actual photos from two hundred million miles up. Some engineers, and the operators at Johns Hopkins, must be awfully proud right about now.
