Pasadena, CA – NASA’s Juno mission to Jupiter, which has been in orbit around the gas giant since July 4, 2016, will remain in its current 53-day orbit for the remainder of the mission. This will allow Juno to accomplish its science goals, while avoiding the risk of a previously-planned engine firing that would have reduced the spacecraft’s orbital period to 14 days.
“Juno is healthy, its science instruments are fully operational, and the data and images we’ve received are nothing short of amazing,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “The decision to forego the burn is the right thing to do — preserving a valuable asset so that Juno can continue its exciting journey of discovery.”
Washington, D.C. – As Super Bowl LI in Houston Texas approaches and players, coaches and a host of personnel behind the scenes prepare for the big game in Space City, NASA remains on the cutting edge of human space exploration, setting its sights on the journey to Mars.
A football player’s journey to the end zone, though, has a lot more in common to space exploration than one might think.
Here are five similarities.

Pasadena, CA – NASA’s Juno spacecraft will make its fourth flyby over Jupiter’s mysterious cloud tops on Thursday, February 2nd, at 4:57am PST (7:57am EST, 12:57 UTC).
At the time of closest approach (called perijove), Juno will be about 2,670 miles (4,300 kilometers) above the planet’s cloud tops and traveling at a speed of about 129,000 mph (57.8 kilometers per second) relative to the gas giant. All of Juno’s eight science instruments, including the Jovian Infrared Auroral Mapper (JIRAM) instrument, will be on and collecting data during the flyby.

Pasadena, CA – Newly released images showcase the incredible closeness with which NASA’s Cassini spacecraft, now in its “Ring-Grazing” orbits phase, is observing Saturn’s dazzling rings of icy debris.
The views are some of the closest-ever images of the outer parts of the main rings, giving scientists an eagerly awaited opportunity to observe features with names like “straw” and “propellers.” Although Cassini saw these features earlier in the mission, the spacecraft’s current, special orbits are now providing opportunities to see them in greater detail.

Silver Spring, MD – GOES-16, the first spacecraft in NOAA’s next-generation of geostationary satellites, has sent the first high-resolution images from its Advanced Baseline Imager (ABI) instrument. Included among them are a composite color full-disk visible image of the Western Hemisphere captured on January 15th, 2017.
Created using several of the ABI’s 16 spectral channels, the full-disk image offers an example the satellite’s advanced technology.

Pasadena, CA – Where should NASA’s Juno spacecraft aim its camera during its next close pass of Jupiter on February 2nd? You can now play a part in the decision.
For the first time, members of the public can vote to participate in selecting all pictures to be taken of Jupiter during a Juno flyby. Voting begins Thursday, January 19th at 11:00am PST (2:00pm EST) and concludes on January 23rd at 9:00am PST (noon EST).
“We are looking forward to people visiting our website and becoming part of the JunoCam imaging team,” said Candy Hansen, Juno co-investigator from the Planetary Science Institute, Tucson, Arizona. “It’s up to the public to determine the best locations in Jupiter’s atmosphere for JunoCam to capture during this flyby.”
Washington, D.C. – Eugene Cernan, the last man to walk on the moon, died Monday, January 16th, surrounded by his family.
Cernan, a Captain in the U.S. Navy, left his mark on the history of exploration by flying three times in space, twice to the moon. He also holds the distinction of being the second American to walk in space and the last human to leave his footprints on the lunar surface.
He was one of 14 astronauts selected by NASA in October 1963. He piloted the Gemini 9 mission with Commander Thomas P. Stafford on a three-day flight in June 1966. Cernan logged more than two hours outside the orbiting capsule.

Pasadena, CA – A series of atmospheric rivers that brought drought-relieving rains, heavy snowfall and flooding to California this week is highlighted in a new movie created with satellite data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite.
The images of atmospheric water vapor were collected by AIRS between January 7th and 11th. They show the amount of moisture present in the atmosphere and its movement across the Pacific Ocean to the United States, where much of it fell as rain or snow.

Washington, D.C. – Searching for planets around other stars is a tricky business. They’re so small and faint that it’s hard to spot them. But a possible planet in a nearby stellar system may be betraying its presence in a unique way: by a shadow that is sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding a young star.
The planet itself is not casting the shadow. But it is doing some heavy lifting by gravitationally pulling on material near the star and warping the inner part of the disk. The twisted, misaligned inner disk is casting its shadow across the surface of the outer disk.

Pasadena, CA – NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively.
“Lucy will visit a target-rich environment of Jupiter’s mysterious Trojan asteroids, while Psyche will study a unique metal asteroid that’s never been visited before,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “This is what Discovery Program missions are all about – boldly going to places we’ve never been to enable groundbreaking science.”
