NASA’s Juno Spacecraft data used to make 3-D Infrared Movie of Jupiter’s North Pole

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists working on NASA’s Juno mission to Jupiter shared a 3-D infrared movie depicting densely packed cyclones and anticyclones that permeate the planet’s polar regions, and the first detailed view of a dynamo, or engine, powering the magnetic field for any planet beyond Earth.

Those are among the items unveiled during the European Geosciences Union General Assembly in Vienna, Austria, on Wednesday, April 11th.

Juno mission scientists have taken data collected by the spacecraft’s Jovian InfraRed Auroral Mapper (JIRAM) instrument and generated the 3-D fly-around of the Jovian world’s north pole. Imaging in the infrared part of the spectrum, JIRAM captures light emerging from deep inside Jupiter equally well, night or day.

NASA’s Juno Spacecraft provides fascinating discoveries about Jupiter

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought.

“We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. “It was a long trip to get to Jupiter, but these first results already demonstrate it was well worth the journey.”

Tennessee Vols play Kansas State at Thompson-Boling Arena, Saturday

 

Tennessee (11-9/4-4 SEC) vs. Kansas State (15-5/4-4 BIG 12)

Saturday, January 28th, 2017 | 1:00pm CT
Knoxville, TN | Thompson-Boling Arena

Tennessee Volunteers - UT VolsKnoxville, TN – Tennessee breaks from conference play and closes out its three-game homestand when it hosts Kansas State on Saturday as part of the SEC/Big 12 Challenge Presented by Sonic. Tipoff is at 1:00pm CT on ESPN2.

Saturday’s game marks the second time in three seasons that Tennessee (11-9, 4-4 SEC) has faced Kansas State (15-5, 4-4 Big 12) in the SEC/Big 12 Challenge. The Wildcats visited Knoxville as part of the cross-conference showcase in 2014, with the Vols claiming a narrow 65-64 victory in that contest.

UT is 1-1 all-time in the SEC/Big 12 Challenge after falling at TCU last season.

NASA advances Exploration Objectives in 2016

 

Written by Bob Jacobs / Allard Beutel
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In 2016, NASA drove advances in technology, science, aeronautics and space exploration that enhanced the world’s knowledge, innovation, and stewardship of Earth.

“This past year marked record-breaking progress in our exploration objectives,” said NASA Administrator Charles Bolden. “We advanced the capabilities we’ll need to travel farther into the solar system while increasing observations of our home and the universe, learning more about how to continuously live and work in space, and, of course, inspiring the next generation of leaders to take up our Journey to Mars and make their own discoveries.”

NASA’s Cyclone Global Navigation Satellite System satellites to help with hurricane forecasts

 

Written by Alan Buis
NASA Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA is set to launch its first Earth science small satellite constellation, which will help improve hurricane intensity, track and storm surge forecasts, on December 12th from Cape Canaveral Air Force Station in Florida.

The Cyclone Global Navigation Satellite System (CYGNSS) hurricane mission will measure previously unknown details crucial to accurately understanding the formation and intensity of tropical cyclones and hurricanes. Derek Posselt of NASA’s Jet Propulsion Laboratory, Pasadena, California, is the deputy principal investigator.

NASA - National Aeronautics and Space AdministrationPasadena, CA – Hurricane forecasters use many different types of data to forecast a storm’s intensity and track. NASA satellites and airborne instruments, including several developed and operated by NASA’s Jet Propulsion Laboratory, Pasadena, California, contribute to scientists’ understanding of tropical cyclones and help improve forecasts.

Here are some of the latest data on Hurricane Matthew from JPL-developed satellites and instruments:

NASA announces Jason-3 Satellite creates it’s first Global Ocean Map

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Jason-3, a new U.S.-European oceanography satellite mission with NASA participation, has produced its first complete science map of global sea surface height, capturing the current signal of the 2015-16 El Niño.

The map was generated from the first 10 days of data collected once Jason-3 reached its operational orbit of 830 miles (1,336 kilometers) last month. It shows the state of the ongoing El Niño event that began early last year. After peaking in January, the high sea levels in the eastern Pacific are now beginning to shrink.

The U.S./European Jason-3 satellite has produced its first map of sea surface height, which corresponds well to data from its predecessor, Jason-2. Higher-than-normal sea levels are red; lower-than-normal sea levels are blue. El Nino is visible as the red blob in the eastern equatorial Pacific. (NASA/JPL Ocean Surface Topography Team)
