Reexamination of NASA Galileo orbiter data yields new evidence of Plumes from Jupiter’s moon Europa

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life. The data provide independent evidence that the moon’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell.

Data collected by NASA’s Galileo spacecraft in 1997 were put through new and advanced computer models to untangle a mystery — a brief, localized bend in the magnetic field — that had gone unexplained until now.

NASA’s Jet Propulsion Laboratory gets visit from U.S. Vice President Mike Pence

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A week before NASA launches its next mission to Mars, U.S. Vice President Mike Pence toured on Saturday, April 28th, the birthplace of numerous past, present and future space missions at the agency’s Jet Propulsion Laboratory in Pasadena, California.

The afternoon visit by the Vice President, his wife, Karen, and daughter Charlotte, included a stop in JPL’s Mission Control, where engineers will communicate with NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight).

NASA detects Hydrogen Sulfide in clouds on Uranus

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Even after decades of observations and a visit by NASA’s Voyager 2 spacecraft, Uranus held on to one critical secret — the composition of its clouds. Now, one of the key components of the planet’s clouds has finally been verified.

A global research team that includes Glenn Orton of NASA’s Jet Propulsion Laboratory in Pasadena, California, has spectroscopically dissected the infrared light from Uranus captured by the 26.25-foot (8-meter) Gemini North telescope on Hawaii’s Mauna Kea. They found hydrogen sulfide, the odiferous gas that most people avoid, in Uranus’ cloud tops. The long-sought evidence was published in the April 23rd issue of the journal Nature Astronomy.

Arriving at Uranus in 1986, Voyager 2 observed a bluish orb with extremely subtle features. A haze layer hid most of the planet's cloud features from view. (NASA/JPL-Caltech)

NASA’s Kepler Mission to end when Spacecraft runs out of Fuel

 

Written by Charlie Sobeck
NASA’s Kepler Space Telescope mission

NASA - National Aeronautics and Space AdministrationSilicon Valley, CA – Trailing Earth’s orbit at 94 million miles away, the Kepler space telescope has survived many potential knock-outs during its nine years in flight, from mechanical failures to being blasted by cosmic rays.

At this rate, the hardy spacecraft may reach its finish line in a manner we will consider a wonderful success. With nary a gas station to be found in deep space, the spacecraft is going to run out of fuel. We expect to reach that moment within several months.

In 2013, Kepler’s primary mission ended when a second reaction wheel broke, rendering it unable to hold its gaze steady at the original field of view.

NASA’s THEMIS Mission helps reveal mystery of Pulsating Aurora

 

Written by Mara Johnson-Groh
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Sometimes on a dark night near the poles, the sky pulses a diffuse glow of green, purple and red. Unlike the long, shimmering veils of typical auroral displays, these pulsating auroras are much dimmer and less common.

While scientists have long known auroras to be associated with solar activity, the precise mechanism of pulsating auroras was unknown. Now, new research, using data from NASA’s Time History of Events and Macroscale Interactions during Substorms — or THEMIS — mission and Japan’s Exploration of energization and Radiation in Geospace — shortened to ERG, or also known as Arase — satellite, has finally captured the missing link thought responsible for these auroras.

NASA’s Cassini Spacecraft data reveals Saturn’s moon Titan has Sea Level elevation

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA –  Saturn’s moon Titan may be nearly a billion miles away from Earth, but a recently published paper based on data from NASA’s Cassini spacecraft reveals a new way this distant world and our own are eerily similar. Just as the surface of oceans on Earth lies at an average elevation that we call “sea level,” Titan’s seas also lie at an average elevation.

This is the latest finding that shows remarkable similarities between Earth and Titan, the only other world we know of in our solar system that has stable liquid on its surface.

Ligeia Mare, shown in here in data obtained by NASA's Cassini spacecraft, is the second largest known body of liquid on Saturn's moon Titan. It is filled with liquid hydrocarbons, such as ethane and methane, and is one of the many seas and lakes that bejewel Titan's north polar region. (NASA/JPL-Caltech/ASI/Cornell)

NASA’s Jet Propulsion Laboratory 2018 Missions and Activities

 

Written by Elyssia Widjaja
NASA’s Jet Propulsion Laboratory Newsroom

NASA - National Aeronautics and Space AdministrationPasadena, CA – The year 2017 marked several milestones in science, technology and flight projects for NASA’s Jet Propulsion Laboratory, Pasadena, California. Voyager 1 returned data from interstellar space as it surpassed 40 years in flight.

NASA’s Cassini Spacecraft ended its 13-year tour of Saturn. JPL celebrated the 25th anniversary of the launch of the Earth-orbiting Topex/Poseidon satellite.

As JPL turns 82 in 2018, its missions and activities will continue to inspire. Here is a preview of events planned for JPL (some dates subject to change):

NASA’s Stratospheric Observatory for Infrared Astronomy observes Magnetic Fields in the Universe

 

Written by Nicholas A. Veronico
NASA Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, is preparing for its 2018 observing campaign, which will include observations of celestial magnetic fields, star-forming regions, comets, Saturn’s giant moon Titan and more.

This will be the fourth year of full operations for SOFIA, with observations planned between February 2018 and January 2019. Research flights will be conducted primarily from SOFIA’s home base at NASA’s Armstrong Flight Research Center.

NASA 2017 Highlights

 

Written by Jen Rae Wang / Allard Beutel
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The Moon became a key focus point for NASA in 2017, whether it was blocking out the Sun during one of the most-viewed events in U.S. history, or reinvigorating the agency’s human space exploration plans.

One of the numerous NASA-related activities and actions the Trump Administration did in 2017 was to reconstitute the National Space Council. During its first meeting on October 5th, Vice President Mike Pence directed NASA to develop a plan to help extend human exploration across our solar system, and return astronauts to the Moon in preparation for human missions to Mars and other destinations.
