JOI: NASA’s Juno arrives at Jupiter on July 4


Mission Trailer Video: Secrets lie deep within Jupiter, shrouded in the solar system’s strongest magnetic field and most lethal radiation belts. On July 4, 2016, NASA’s Juno spacecraft will plunge into uncharted territory, entering orbit around the gas giant and passing closer than any spacecraft before. Juno will see Jupiter for what it really is, but first it must pass the trial of orbit insertion.

“Beautiful” fireball seen, recorded

Kim Doran emailed us on June 12 asking if anyone had seen what she witnessed the night before: a brilliant, multi-colored fireball meteor. Fireballs are meteors that flare to become brighter than the planet Venus.

We don’t know if other human observers saw the meteor’s brilliant fall but NASA’s automated cameras on the campuses of Hiram College and Oberlin College recorded the June 11 event at 10:17 PM EDT.

“(I) saw what I thought was a very large shooting star … then brighter flash and very thick trail with quick red, bright white, and some blue.” She said she is 57 years of age and has never seen anything quite like this before. “Beautiful!”

Launched from Earth in 2011, the Juno spacecraft will arrive at Jupiter on July 4, 2016 to study the giant planet from an elliptical, polar orbit. Juno will repeatedly dive between the planet and its intense belts of charged particle radiation, coming only 5,000 kilometers (about 3,000 miles) from the cloud tops at closest approach.

Juno’s primary goal is to improve our understanding of Jupiter’s formation and evolution. The spacecraft will spend a year investigating the planet’s origins, interior structure, deep atmosphere, and magnetosphere. Juno’s study of Jupiter will help us to understand the history of our own solar system and provide new insight into how planetary systems form and develop in our galaxy and beyond.

Juno’s principal investigator is Scott Bolton of Southwest Research Institute in San Antonio, Texas. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., manages the mission. Lockheed Martin Space Systems of Denver, Colo., built the spacecraft. The Italian Space Agency, Rome, contributed an infrared spectrometer instrument and a portion of the radio science experiment.

The CAA will host a public star party for the Medina County Park District at 9:00 PM at Letha House Park West. See Mars, Saturn, Jupiter, and more! A cloudy night alternative program will be offered should weather conditions be an issue. Members: please bring your scope to help if you can.

Road closure/detour: Due to a Medina County Highway Engineer’s road improvement construction project, Spencer Lake Road will be closed just east of Richman Road where you would normally access Letha House Park West. This section of road will be closed from June 6 through the end of July 2016. Click HERE for a detour map.

CAA member photographs Indonesian eclipse

March 9 Total Solar Eclipse by Steve Korylak

CAA member and eclipse chaser Steve Korylak followed the Sun to Indonesia for the March 9 total solar eclipse. He viewed and photographed the event from the deck of a ship positioned for an optimal view of totality. Here are his photographs and his story….

“Not bad for being on a moving ship! The eclipse lasted two minutes, forty seconds; I planned to photograph for one minute, look at the sun visually for one minute and take a movie for the last 40 seconds. I had rehearsed this the day before so I would be prepared. Timing the interval between shots so I did not overload the camera buffer. I had a solar filter on the lens to record the partial phases. Near totality, I looked for shadow bands on the side of the white ship and did not see them. When I took off the filter the focus changed, even though I had it taped so it would not move; this caused me to miss the diamond ring and bailey’s beads. I had to refocus — still slightly off — and started taking pictures. Then the eclipse was over; no visual, no movie. Learning experience!”

Photo Info: Inner corona – Nikon D1500 (APS-size sensor) 1/4000 sec., f/11, ISO 1000, 300mm lens with 2X teleconverter. Outer  corona – same hardware, 1/60 sec., f/11, ISO 1000. The lens was f/5.6 but with the teleconverter it is equivalent to f/11. shot in raw mode for maximum detail.
