NASA Releases Juno's First Stunning Close-Ups of Jupiter's Giant Storm (theverge.com)

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.

      The probe will fail due to radiation exposure, but the orbit was designed to minimize that. The main radiation belts are farther out, and the polar orbit actually avoids the highest concentration zones. An explanation: "The orbits were carefully planned in order to minimize contact with Jupiter's dense radiation belts, which can damage spacecraft electronics and solar panels, by exploiting a gap in the radiation envelope near the planet, passing through a region of minimal radiation. The "Juno Radiation Vault", with 1-centimeter-thick titanium walls, also aids in protecting Juno's electronics. Despite the intense radiation, JunoCam and the Jovian Infrared Auroral Mapper (JIRAM) are expected to endure at least eight orbits, while the Microwave Radiometer (MWR) should endure at least eleven orbits. Juno will receive much lower levels of radiation in its polar orbit than the Galileo orbiter received in its equatorial orbit. Galileo was damaged by radiation during its mission, including an LED diode in its data recording system."

    In terms of orbital distances:
    - geostationary orbit around the Earth (where all of our communication satellites are) is 42,164 km (26,199 mi). So Juno was 21% of this distance from the red spot at the time;
    - the Moon is about 384,399 km from Earth, so Juno was about 2.3% of the distance to the Moon;
    - the ISS orbits at about 405km above the Earth (NYC to Rochester - about 50km/30mi short of Niagra Falls), so Juno was just over 22 times that distance away.

    At its closes point, Juno was 3,400km (2,100mi) above Jupiter, so that's:

      Robotic exploration is absolutely the right tasks for this bit of exploration, if only due to the radiation environment around Jupiter. I don't think anyone argues that robotic missions don't have value.

      As a comparison, lets look at the Curiosity rover on mars. As of Late January this year, it had driven a total of 15km on Mars in roughly 1700 days. It's done a lot of really great work, but it's slow, painstaking, and somewhat limited. If you were to put a human field geologist on Mars, with an appropriate quad-bike type vehicle, she or he would likely be able to cover the same distance within a matter of hours. Also, having that brain behind the Mk-1 eyeball, would allow them to quickly sort out and spot relevant bits of geology. In terms of pure science, putting a team of humans there with appropriate training would be orders of magnitude more efficient.

      The reality, though, is that for these kinds of things, science isn't the point of the mission, it's just what you do when you get there.
