MEDIA ADVISORY M19-034
Media are invited to hear experts from around the world discuss the latest research on near-Earth objects (NEOs) at the International Academy of Astronautics’ 2019 Planetary Defense Conference, Monday, April 29 through Friday, May 3 at The Hotel at the University of Maryland.
NEOs include asteroids and comets that orbit our Sun and come within 30 million miles of Earth’s orbit, where some may pose an impact hazard to our planet. NASA experts will talk about the agency’s first mission to demonstrate a technique to change the motion of an asteroid in space and other aspects of the nation’s planetary defense program.
This Fourth of July, NASA’s solar-powered Juno spacecraft will arrive at Jupiter after an almost five-year journey. News briefings, photo opportunities and other media events will be held at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, and air live on NASA Television and the agency’s website.
Juno was launched August 5, 2011 from Cape Canaveral in Florida on an Atlas V rocket. It was estimated to take five years for the satellite to reach Jupiter, the only other gas giant without a dedicated satellite.
In the evening of July 4, Juno will perform a suspenseful orbit insertion maneuver, a 35-minute burn of its main engine, to slow the spacecraft by about 1,212 miles per hour (542 meters per second) so it can be captured into the gas giant’s orbit. Once in Jupiter’s orbit, the spacecraft will circle the Jovian world 37 times during 20 months, skimming to within 3,100 miles (5,000 kilometers) above the cloud tops. This is the first time a spacecraft will orbit the poles of Jupiter, providing new answers to ongoing mysteries about the planet’s core, composition and magnetic fields.
Juno will improve our understanding of the solar system’s beginnings by revealing the origin and evolution of Jupiter.
Specifically, Juno will…
- Determine how much water is in Jupiter’s atmosphere, which helps determine which planet formation theory is correct (or if new theories are needed)
- Look deep into Jupiter’s atmosphere to measure composition, temperature, cloud motions and other properties
- Map Jupiter’s magnetic and gravity fields, revealing the planet’s deep structure
- Explore and study Jupiter’s magnetosphere near the planet’s poles, especially the auroras – Jupiter’s northern and southern lights – providing new insights about how the planet’s enormous magnetic force field affects its atmosphere.
Juno’s principal goal is to understand the origin and evolution of Jupiter. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars.
With its suite of science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras.
While the events below are for the media, the public is invited to watch each of the events starting on June 16. The following are televised events are:
NASA TV Events Schedule
NASA will host a media teleconference at 1 p.m. EDT on Wednesday, June 3, to discuss the Hubble Space Telescope’s surprising observations of how Pluto’s moons behave, and how these new discoveries are being used in the planning for the New Horizons Pluto flyby in July.
Participants in the teleconference will be:
- John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington
- Mark Showalter, senior research scientist at the SETI Institute in Mountain View, California
- Douglas Hamilton, professor of astronomy at the University of Maryland, College Park
- John Spencer, scientist at Southwest Research Institute in Boulder, Colorado
- Heidi Hammel, executive vice president of the Association of Universities for Research in Astronomy in Washington
To participate by phone, reporters must contact Felicia Chou at 202-358-0257 or firstname.lastname@example.org and provide their media affiliation no later than 10 a.m. Wednesday.
