The public is invited to a free talk called “The Juno Mission to Jupiter,” presented by John (Jack) Connerney, at the Mary Pickford Theater (3rd Floor, James Madison Building, Library of Congress, Washington, D.C.) on Thursday, June 23, from 11:30 a.m. to 12:30 p.m. EDT.jupiter_1_0

Connerney is an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He is the Deputy Principal Investigator for the Juno Mission, and lead for the magnetometer investigation. The Juno spacecraft, launched in 2011 and arriving at Jupiter on July 4, 2016, will orbit the planet for about 18 months to study the origin and evolution of Jupiter and deepen our understanding of the solar system’s beginnings.

“Juno is the first spacecraft to orbit Jupiter from pole-to-pole, racing across Jupiter’s cloud tops at unprecedented speed, and ducking below the most hazardous radiation belts in the solar system, truly going where no spacecraft has gone before,” said Connerney. “I can’t wait to see what we’ll find there.”

Juno will unlock many of Jupiter’s secrets:

  • Measuring the abundance of water in Jupiter’s atmosphere, a critical test of planet formation theory;
  • Peering beneath the clouds to measure composition, temperature, and fluid motions in the deep interior;
  • Mapping Jupiter’s magnetic and gravity fields, revealing the planet’s deep structure;
  • Exploring Jupiter’s magnetosphere from a unique vantage point above the gas giant’s poles, traversing the auroral ovals – Jupiter’s northern and southern lights – providing new insights about the planet’s enormous magnetosphere and powerful aurorae.
