NASA’s Juno Spacecraft to Risk Jupiter’s Fireworks for Science

On July 4, NASA will fly a solar-powered spacecraft the size of a basketball court within 2,900 miles (4,667 kilometers) of the cloud tops of our solar system’s largest planet. As of Thursday, Juno is 18 days and 8.6 million miles (13.8 million kilometers) from Jupiter. On the evening of July 4, Juno will fire its main engine for 35 minutes, placing it into a polar orbit around the gas giant. During the flybys, Juno will probe beneath the obscuring cloud cover of Jupiter and study its auroras to learn more about the planet's origins, structure, atmosphere and magnetosphere. "At this time last year our New Horizons spacecraft was closing in for humanity’s first close views of Pluto,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. “Now, Juno is poised to go closer to Jupiter than any spacecraft ever before to unlock the mysteries of what lies within.” A series of 37 planned close approaches during the mission will eclipse the previous record for Jupiter set in 1974 by NASA’s Pioneer 11 spacecraft of 27,000 miles (43,000 kilometers). Getting this close to Jupiter does not come without a price -- one that will be paid each time Juno's orbit carries it toward the swirling tumult of orange, white, red and brown clouds that cover the gas giant. "We are not looking for trouble, we are looking for data," said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. "Problem is, at Jupiter, looking for the kind of data Juno is looking for, you have to go in the kind of neighborhoods where you could find trouble pretty quick.” The source of potential trouble can be found inside Jupiter itself. Well below the Jovian cloud tops is a layer of hydrogen under such incredible pressure it acts as an electrical conductor. Scientists believe that the combination of this metallic hydrogen along with Jupiter's fast rotation -- one day on Jupiter is only 10 hours long -- generates a powerful magnetic field that surrounds the planet with electrons, protons and ions traveling at nearly the speed of light. The endgame for any spacecraft that enters this doughnut-shaped field of high-energy particles is an encounter with the harshest radiation environment in the solar system. "Over the life of the mission, Juno will be exposed to the equivalent of over 100 million dental X-rays," said Rick Nybakken, Juno's project manager from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. "But, we are ready. We designed an orbit around Jupiter that minimizes exposure to Jupiter’s harsh radiation environment. This orbit allows us to survive long enough to obtain the tantalizing science data that we have traveled so far to get.” Juno's orbit resembles a flattened oval. Its design is courtesy of the mission's navigators, who came up with a trajectory that approaches Jupiter over its north pole and quickly drops to an altitude below the planet's radiation belts as Juno races toward Jupiter's south pole. Each close flyby of the planet is about one Earth day in duration. Then Juno's orbit will carry the spacecraft below its south pole and away from Jupiter, well beyond the reach of harmful radiation. While Juno is replete with special radiation-hardened electrical wiring and shielding surrounding its myriad of sensors, the highest profile piece of armor Juno carries is a first-of-its-kind titanium vault, which contains the spacecraft's flight computer and the electronic hearts of many of its science instruments. Weighing in at almost 400 pounds (172 kilograms), the vault will reduce the exposure to radiation by 800 times of that outside of its titanium walls. Without the vault, Juno’s electronic brain would more than likely fry before the end of the very first flyby of the planet. But, while 400 pounds of titanium can do magical things, it can't do it forever in an extreme radiation environment like that on Jupiter. The quantity and energy of the high-energy particles is just too much. However, Juno’s special orbit allows the radiation dose and the degradation to accumulate slowly, allowing Juno to do a remarkable amount of science for 20 months. “Over the course of the mission, the highest energy electrons will penetrate the vault, creating a spray of secondary photons and particles,” said Heidi Becker, Juno’s Radiation Monitoring Investigation lead. “The constant bombardment will break the atomic bonds in Juno’s electronics.” The Juno spacecraft launched Aug. 5, 2011 from Cape Canaveral, Florida. JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. Juno is part of NASA's New Frontiers Program, which is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama, for NASA's Science Mission Directorate. Lockheed Martin Space Systems, Denver, built the spacecraft. The California Institute of Technology in Pasadena manages JPL for NASA.

Cygnus Cargo Craft Released From Space Station
 <https://www.nasa.gov/sites/default/files/thumbnails/image/27594170151_e2625a7d6b_o.jpg>
Orbital ATK's Cygnus cargo craft is released by the International Space Station's Canadarm2 robotic arm in this photograph by European Space Agency astronaut Tim Peake, who wrote <https://twitter.com/astro_timpeake/status/742727126311395329>: "We just said goodbye to #Cygnus OA-6 – a great spacecraft & thanks to everyone involved." Cygnus departed at 9:30 a.m. EDT on June 14, 2016, while the space station was flying above Paraguay Aboard Cygnus is the Spacecraft Fire Experiment-1 (Saffire-1) <http://www.nasa.gov/feature/nasa-ignites-fire-experiment-aboard-space-cargo-ship>, the first of a three-part experiment that will be conducted over the course of three flights to investigate large-scale flame spread and material flammability limits in long duration microgravity At 3:30 p.m., once the cargo craft reached a safe distance from the space station, ground controllers at NASA's Glenn Research Center in Cleveland, Ohio initiated the sequence for Saffire-1 <http://www.nasa.gov/feature/nasa-ignites-fire-experiment-aboard-space-cargo-ship>. Controllers at Orbital ATK in Dulles, Virginia, activated the experiment at 4:55 p.m. Telemetry indicated the cotton-fiberglass material blend is now burning successfully. Cygnus will continue to orbit Earth for up to eight days as it transmits hi-resolution imagery and data from the Saffire experiment. Following complete data transmission, the Cygnus spacecraft will complete its destructive entry into the Earth’s atmosphere on June 22.



May 19, 2000, Early Morning Liftoff of Atlantis on STS-101 Mission. The shuttle launches for me were amazing and the night launches majestic. I am so happy I was able to share them with so many of you. 
 <https://www.nasa.gov/sites/default/files/thumbnails/image/sts101-s-007.jpg>
Flames from the solid rocket boosters lit up the clouds of smoke and steam trailing behind space shuttle Atlantis on May 19, 2000, as it lifted off into the pre-dawn sky on mission STS-101. Launch from pad 39A at NASA's Kennedy Space Center occurred on time at 6:11:10 a.m. EDT. The mission took the crew of six American astronauts and one Russian cosmonaut to the International Space Station to deliver logistics and supplies, as well as to prepare the station for the arrival of the Zvezda Service Module, launched by Russia on July 12, 2000 <http://www.nasa.gov/mission_pages/station/structure/iss_assembly_1r.html>. The astronauts equipped the station with new or replacement gear and transferred more than a ton of supplies into the space station for use by future residents of the orbiting laboratory, and Mission Specialists James Voss and Jeff Williams completed one spacewalk <http://www.nasa.gov/mission_pages/station/structure/iss_assembly_2a2a.html>. After a 10-day mission, Atlantis landed on May 29 at 2:20 a.m. EDT. STS-101 was the shuttle program's third space station assembly flight. It was the first space flight and spacewalk for NASA astronaut Jeff Williams, who is currently living and working aboard the station as a member of the Expedition 47 <http://www.nasa.gov/mission_pages/station/expeditions/expedition47/index.html> crew.
