Pasadena, CA – NASA scientists, including many from NASA’s Jet Propulsion Laboratory, Pasadena, California, are crisscrossing the globe in 2017 — from a Hawaiian volcano to Colorado mountaintops and west Pacific islands — to investigate critical scientific questions about how our planet is changing and what impacts humans are having on it.
Field experiments are an important part of NASA’s Earth science research.

Pasadena, CA – From the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon.
The image combines two separate exposures taken on November 20th, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. The images were taken to calibrate HiRISE data, since the reflectance of the moon’s Earth-facing side is well known.

Pasadena, CA – In a first-of-its-kind collaboration, NASA’s Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due to the gravitational field of at least one foreground cosmic object. This technique is useful for finding low-mass bodies orbiting stars, such as planets. In this case, the observations revealed a brown dwarf.
Brown dwarfs are thought to be the missing link between planets and stars, with masses up to 80 times that of Jupiter. But their centers are not hot or dense enough to generate energy through nuclear fusion the way stars do.

Pasadena, CA – NASA’s Juno spacecraft entered safe mode Tuesday, October 18th at about 10:47pm PDT (October 19th at 1:47am EDT). Early indications are a software performance monitor induced a reboot of the spacecraft’s onboard computer. The spacecraft acted as expected during the transition into safe mode, restarted successfully and is healthy.
High-rate data has been restored, and the spacecraft is conducting flight software diagnostics. All instruments are off, and the planned science data collection for today’s close flyby of Jupiter (perijove 2), did not occur.

Pasadena, CA – No extension cord is long enough to reach another planet, and there’s no spacecraft charging station along the way. That’s why researchers are hard at work on ways to make spacecraft power systems more efficient, resilient and long-lasting.
“NASA needs reliable long-term power systems to advance exploration of the solar system,” said Jean-Pierre Fleurial, supervisor for the thermal energy conversion research and advancement group at NASA’s Jet Propulsion Laboratory, Pasadena, California. “This is particularly important for the outer planets, where the intensity of sunlight is only a few percent as strong as it is in Earth orbit.”

Washington, D.C. – Two’s company, but three might not always be a crowd — at least in space.
Astronomers using NASA’s Hubble Space Telescope, and a trick of nature, have confirmed the existence of a planet orbiting two stars in the system OGLE-2007-BLG-349, located 8,000 light-years away towards the center of our galaxy.
The planet orbits roughly 300 million miles from the stellar duo, about the distance from the asteroid belt to our sun. It completes an orbit around both stars roughly every seven years. The two red dwarf stars are a mere 7 million miles apart, or 14 times the diameter of the moon’s orbit around Earth.

Pasadena, CA – NASA’s Juno spacecraft has sent back the first-ever images of Jupiter’s north pole, taken during the spacecraft’s first flyby of the planet with its instruments switched on. The images show storm systems and weather activity unlike anything previously seen on any of our solar system’s gas-giant planets.
Juno successfully executed the first of 36 orbital flybys on August 27th when the spacecraft came about 2,500 miles (4,200 kilometers) above Jupiter’s swirling clouds.

Washington, D.C. – This Saturday at 5:51am PDT, (7:51am CDT, 12:51 UTC) NASA’s Juno spacecraft will get closer to the cloud tops of Jupiter than at any other time during its prime mission.
At the moment of closest approach, Juno will be about 2,600 miles (4,200 kilometers) above Jupiter’s swirling clouds and traveling at 130,000 mph (208,000 kilometers per hour) with respect to the planet. There are 35 more close flybys of Jupiter scheduled during its prime mission (scheduled to end in February of 2018).

Pasadena, CA – Each year, NASA funds a handful of futuristic concepts to push forward the boundaries of space exploration. These early-stage proposals are selected with the hope of developing new ideas into realistic proofs-of-concept.
From August 23rd to 25th, the NASA Innovative Advanced Concepts (NIAC) symposium will host presentations on 28 proposals, including five from NASA’s Jet Propulsion Laboratory, Pasadena, California.

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.
