Using data from @NASA's Moon Mineralogy Mapper (M3) instrument, scientists have identified three specific signatures that definitively prove there is water ice at the surface of the Moon. These ice deposits are patchily distributed and could possibly be ancient. At the southern pole, most of the ice is concentrated at lunar craters, while ice at the northern pole is more widely, but sparsely spread.
Most of the newfound water ice lies in the shadows of craters near the poles, where the warmest temperatures never reach above minus 250 degrees Fahrenheit. Because of the very small tilt of the Moon's rotation axis, sunlight never reaches these regions.

Tête-à-tête
Saturn's moon Tethys disappears behind Titan as observed by Cassini on Nov. 26, 2009. Tethys is about 660 miles (1,070 kilometers) across. At about 3,200 miles (5,100 kilometers) wide, Titan is larger than the planet Mercury, and was much closer to Cassini than #Tethys at the time of this image. #Titan is planet-like in another way: it's wrapped in a thick atmosphere, which can be clearly seen here where it overlaps icy Tethys in the distance beyond.

Cassini captured this natural-color image at a distance of approximately 620,000 miles (1 million kilometers) from Titan.

OMG! With a new research plane and a new base to improve its chances of outsmarting hurricanes, NASA's Oceans Melting Greenland campaign takes to the sky this week.

#OTD in 1977, Voyager 2 launched from @KennedySpaceCenter.
It is the only spacecraft to have visited #Uranus and #Neptune and is currently making its way to interstellar space, where its twin spacecraft, Voyager 1, has resided since August 2012. During its travels through the outer solar system, Voyager 2 visited all four gas giant planets, and also discovered and photographed many of the planets' moons.
The spacecraft's flyby of Neptune in 1989 set it on a course below the elliptic plane that will eventually take it to interstellar space. In 1998, engineers switched off the spacecraft's nonessential instruments to conserve power. Data from at least some of the six instruments still in operation should be received until at least 2025.

On #WorldPhotoDay, here’s to 15 years of stunning imagery from Spitzer Space Telescope, one of @NASA’s Great Observatories!

Spitzer was designed to observe the universe in infrared light. Launched in 2003 with an expected lifetime of five years, the space telescope has succeeded beyond our wildest expectations.

This image of Cassiopeia A, the remnant of a star that died in a fiery supernova blast, was made combining data from Spitzer and two of its fellow @NASA Great Observatories, Chandra and Hubble.

🤞As the dust storm starts to clear on #Mars, Opportunity’s team hopes to hear from the nearly 15-year-old rover. Visit the link in our bio to read about six things we need to consider during Oppy’s recovery efforts: https://go.nasa.gov/2vQfPQK
This image was taken by #MastCam onboard @NASA’s Mars rover Curiosity on Sol 2133 (Aug. 6, 2018). Scientists expect the dust storm to take weeks to clear.

Where should you land an interplanetary spacecraft?
JPL scientist Ingrid Daubar helped find the best parking spot on Mars for @NASA’s InSight lander to touch down on Nov. 26.

Drops of Jupiter’s Great Red Spot give the atmosphere a layered appearance.
The easternmost edge of #Jupiter’s Great Red Spot and surrounding south tropical disturbance are captured in this image from @NASA’s Juno spacecraft. At left, wispy tendrils from the Red Spot partially obscure cloud features below.
Jupiter's appearance is a tapestry of vivid colors and swirling atmospheric vortices. Many aspects of the planet’s atmosphere are still a mystery. For example, the origin of individual storms or churning cloud features is unknown. By studying Jupiter’s weather up close for the first time, Juno is helping researchers better understand how atmospheres work in general – including our own. What we learn about Jupiter’s atmosphere will also help scientists understand how gas-giant planets work in general, including those now being discovered beyond our solar system.
This color-enhanced image was taken at 3:01 a.m. PDT on April 1, 2018 (6:01 a.m. EDT), as the spacecraft performed its 12th close flyby of Jupiter. At the time, Juno was about 7,900 miles (12,750 kilometers) from the planet's cloud tops, above a southern latitude of approximately 26 degrees.

ASTERIA wins Small Satellite Mission of the Year Award. This CubeSat tests miniaturized technology for precisely measuring the brightness of stars.
The award is given to a mission that has "demonstrated a significant improvement in the capability of small satellites," according to the award description.
The mission is a collaboration between NASA’s Jet Propulsion Laboratory, Pasadena, California, and the Massachusetts Institute of Technology, Cambridge.
The award was presented at this month‘s annual Small Satellite Conference in Logan, Utah, hosted by AIAA and Utah State University. Finalists for the award are selected by committee, and the winner is chosen through a public vote.
ASTERIA stands for Arcsecond Space Telescope Enabling Research in Astrophysics. For its primary mission, ASTERIA was designed to test miniaturized technology for precisely measuring the brightness of stars, which includes the ability to stabilize the spacecraft so that it can point itself directly at a star for an extended period of time.
While this technology has been readily demonstrated in larger satellites, shrinking it down to fit inside a small satellite was an engineering challenge. In the future, this technology could be used in satellites to assist in searching for transiting exoplanets.
ASTERIA is a CubeSat, a type of small satellite made of "units" that are 10 centimeters cubed, or about 4 inches on each side. ASTERIA is the size of six CubeSat units, making it roughly 10 centimeters by 20 centimeters by 30 centimeters (3.9 inches by 7.8 inches by 11.8 inches). With its two solar panels unfolded, the satellite is about as long as a skateboard.
Deployed into low-Earth orbit in November 2017, ASTERIA completed its primary mission in February and is now operating in an extended mission. The mission is funded through the JPL Phaeton Program for training early career employees.

Translucent arcs.

Saturn’s rings are perhaps the most recognized feature of any world in our solar system. Cassini spent more than a decade examining them more closely than any spacecraft before it.

The rings are made mostly of particles of water ice that range in size from smaller than a grain of sand to as large as mountains. The ring system extends up to 175,000 miles (282,000 kilometers) from the planet, but for all their immense width, the rings are razor-thin, about 30 feet (10 meters) thick in most places.

From the right angle you can see straight through the rings, as in this natural-color view that looks from south to north. Cassini obtained the images that comprise this mosaic on April 25, 2007, at a distance of approximately 450,000 miles (725,000 kilometers) from Saturn. The Cassini spacecraft ended its mission on Sept. 15, 2017.

So ultrahot right now 🔥
Scientists are discovering why some planets with the ingredients for water can’t sustain H2O molecules. Visit the link in our bio to read more: https://go.nasa.gov/2MkMbN3
These simulated views of the ultrahot Jupiter WASP-121b show what the planet might look like to the human eye from five different vantage points, illuminated to different degrees by its parent star. The images were created using a computer simulation being used to help scientists understand the atmospheres of these ultra-hot planets. Ultrahot Jupiters reflect almost no light, rather like charcoal. However, the daysides of ultrahot Jupiters have temperatures of between 3600°F and 5400°F (2000°C and 3000°C), so the planets produce their own glow, like a hot ember.
