Pasadena, CA – NASA has selected four Discovery Program investigations to develop concept studies for new missions. Although they’re not official missions yet and some ultimately may not be chosen to move forward, the selections focus on compelling targets and science that are not covered by NASA’s active missions or recent selections. Final selections will be made next year.
NASA’s Discovery Program invites scientists and engineers to assemble a team to design exciting planetary science missions that deepen what we know about the solar system and our place in it.

Pasadena, CA – Data collected by NASA’s Juno spacecraft using its Jovian InfraRed Auroral Mapper (JIRAM) instrument point to a new heat source close to the south pole of Io that could indicate a previously undiscovered volcano on the small moon of Jupiter. The infrared data were collected on December 16th, 2017, when Juno was about 290,000 miles (470,000 kilometers) away from the moon.
“The new Io hotspot JIRAM picked up is about 200 miles (300 kilometers) from the nearest previously mapped hotspot,” said Alessandro Mura, a Juno co-investigator from the National Institute for Astrophysics in Rome. “We are not ruling out movement or modification of a previously discovered hot spot, but it is difficult to imagine one could travel such a distance and still be considered the same feature.”

Pasadena, CA – Few missions can match the achievements of NASA’s groundbreaking Voyager 1 and 2 spacecraft during their 40 years of exploration. Here’s a short list of their major accomplishments to date. The Voyager spacecrafts made a lot of planetary firsts
Launched in 1977, the Voyagers delivered many surprises and discoveries from their encounters with the gas giants of the outer solar system: Jupiter, Saturn, Uranus and Neptune.

Pasadena, CA – Humanity’s farthest and longest-lived spacecraft, Voyager 1 and 2, achieve 40 years of operation and exploration this August and September. Despite their vast distance, they continue to communicate with NASA daily, still probing the final frontier.
Their story has not only impacted generations of current and future scientists and engineers, but also Earth’s culture, including film, art and music. Each spacecraft carries a Golden Record of Earth sounds, pictures and messages. Since the spacecraft could last billions of years, these circular time capsules could one day be the only traces of human civilization.

Moffett Field, CA – Scientists using NASA’s Kepler space telescope identified a regular pattern in the orbits of the planets in the TRAPPIST-1 system that confirmed suspected details about the orbit of its outermost and least understood planet, TRAPPIST-1h.
TRAPPIST-1 is only eight percent the mass of our sun, making it a cooler and less luminous star. It’s home to seven Earth-size planets, three of which orbit in their star’s habitable zone — the range of distances from a star where liquid water could pool on the surface of a rocky planet. The system is located about 40 light-years away in the constellation of Aquarius. The star is estimated to be between 3 billion and 8 billion years old.
Washington,D.C. – NASA’s partnership in a future European Space Agency (ESA) mission to Jupiter and its moons has cleared a key milestone, moving from preliminary instrument design to implementation phase.
Designed to investigate the emergence of habitable worlds around gas giants, the JUpiter ICy Moons Explorer (JUICE) is scheduled to launch in five years, arriving at Jupiter in October 2029. JUICE will spend almost four years studying Jupiter’s giant magnetosphere, turbulent atmosphere, and its icy Galilean moons—Callisto, Ganymede and Europa.

Pasadena, CA – NASA’s Juno mission accomplished a close flyby of Jupiter on Monday, March 27th, successfully completing its fourth science orbit.
All of Juno’s science instruments and the spacecraft’s JunoCam were operating during the flyby, collecting data that is now being returned to Earth. Juno’s next close flyby of Jupiter will occur on May 19th, 2017.
NASA’s Juno spacecraft made its fifth flyby over Jupiter’s mysterious cloud tops on Monday, March 27th, at 1:52am PDT (4:52am EDT, 8:52 UTC).

Greenbelt, MD – Launched five years ago on August 5th, 2011, NASA’s Juno mission maneuvered into orbit around Jupiter on July 4th, 2016, joining a long tradition of discovery at the gas giant.
One of the brightest objects in the night sky, Jupiter has enthralled humans since ancient times. Today, scientists believe that learning more about the planet may be the key to discovering our solar system’s origins and formation.
Washington, D.C. – Jupiter’s volcanic moon Io has a thin atmosphere that collapses in the shadow of Jupiter, condensing as ice, according to a new study by NASA-funded researchers. The study reveals the freezing effects of Jupiter’s shadow during daily eclipses on the moon’s volcanic gases.
“This research is the first time scientists have observed this remarkable phenomenon directly, improving our understanding of this geologically active moon,” said Constantine Tsang, a scientist at the Southwest Research Institute in Boulder, Colorado. The study was published August 2nd in the Journal of Geophysical Research.

Washington, D.C. – NASA’s Juno is now poised to shine a spotlight on the origins and interior structure of the largest planet in our solar system.
As we wait for Juno’s first close-up images of Jupiter (to be taken August 27th during the spacecraft’s next pass by the planet), NASA continues to explore our solar system to help answer fundamental questions about how we came to be, where we are going and whether we are alone in the universe.
