While millions of American鈥檚 celebrated July 4th with traditional fanfare and fireworks, the NASA space program marked听the holiday by firing the rockets of its , sending the probe into Jupiter鈥檚 orbit 534 million miles from Earth.
In November, the spacecraft will settle into a tighter polar orbit, and according to NASA-funded researcher and current , will use cutting-edge technology to reveal answers to questions that have puzzled astronomers for more than 400 years.
鈥淔or 37 orbits the craft is going to use ultra-sensitive magnetic and gravity detectors to construct an MRI-like image of the interior that is hidden by thick layers of clouds,鈥 Dowling said. 鈥淭his mission will answer several questions about the formation of Jupiter, which is really the story about the formation of our solar system. For years scientists have questioned whether Jupiter has a rocky core or if it is comprised solely of gas. This 鈥楳RI鈥 will give all of us a completely new way to look at the planet.鈥
The Juno mission also will use a microwave radiometer to search for the existence of water and study the depth and speed of the massive jet streams that streak across the solar system鈥檚 largest planet.
鈥淚 actually have some ‘skin’ in the game because back in the late ’80s and early ’90s I predicted that the jet streams, which are the predominant brown and white stripes, are quite deep,鈥 Dowling said. 鈥淭his will be the first spacecraft that will test that hypothesis.鈥
In addition to being a professor of physics and astronomy at UofL, Dowling served as a researcher for the NASA Voyager II mission that photographed and mapped the surface of Uranus. Dowling is also the lead architect for the used by NASA and researchers around the world to model the weather on Jupiter, Saturn, Uranus and Neptune. 听
