Juno is in a highly-elliptical 53-day orbit around Jupiter. Each orbit includes a close passage over the planet’s cloud deck, where it flies a ground track that extends from Jupiter’s north pole to its south pole. ![]() A south tropical disturbance has just passed Jupiter’s iconic Great Red Spot, and is captured stealing threads of orange haze from the Great Red Spot in this series of color-enhanced images from NASA’s Juno spacecraft.

NASA to let Public pick Juno Spacecraft’s next site for Jupiter PhotosWritten by DC Agle
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.” ![]() This amateur-processed image was taken on Dec. 11, 2016, at 9:27 a.m. PST (12:27 p.m. EST), as NASA’s Juno spacecraft performed its third close flyby of Jupiter.

NASA’s Dawn spacecraft reveals new areas where Ice may hide on CeresWritten by Elizabeth Landau
But newly published studies from Dawn scientists show two distinct lines of evidence for ice at or near the surface of the dwarf planet. Researchers are presenting these findings at the 2016 American Geophysical Union meeting in San Francisco. ![]() This graphic shows a theoretical path of a water molecule on Ceres. Some water molecules fall into cold, dark craters called “cold traps,” where very little of the ice turns into vapor, even over the course of a billion years.

Volunteers examine NASA’s Mars Reconnaissance Orbiter images to find areas worth further studyWritten by Guy Webster
From the comfort of home, the volunteers have been exploring the surface of Mars by reviewing images from the Context Camera (CTX) on NASA’s Mars Reconnaissance Orbiter and identifying certain types of seasonal terrains near Mars’ south pole. ![]() This image shows spidery channels eroded into Martian ground. It is a Sept. 12, 2016, example from HiRISE camera high-resolution observations of more than 20 places that were chosen in 2016 on the basis of about 10,000 volunteers’ examination of Context Camera lower-resolution views of larger areas.

NASA’s Juno spacecraft enters Safe Mode after last Flyby of JupiterWritten by DC Agle
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. ![]() This artist’s concept depicts the Juno spacecraft above Jupiter. The spacecraft will next fly by the planet on Aug. 27th, in the mission’s first up-close science pass. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Juno Spacecraft takes first pictures from Jupiter OrbitWritten by DC Agle / Preston Dyches
“This scene from JunoCam indicates it survived its first pass through Jupiter’s extreme radiation environment without any degradation and is ready to take on Jupiter,” said Scott Bolton, principal investigator from the Southwest Research Institute in San Antonio. “We can’t wait to see the first view of Jupiter’s poles.” ![]() This color view from NASA’s Juno spacecraft is made from some of the first images taken by JunoCam after the spacecraft entered orbit around Jupiter on July 5th (UTC).

NASA Spacecraft images indicate Tsunamis on Mars shaped it’s Coastal areasNASA’s Ames Research Center
“Imagine a huge wall of red water the size of a high-rise building moving towards you at the speed of a jetliner,” said J. Alexis P. Rodriguez, former NASA Postdoctoral Program fellow at NASA’s Ames Research Center in California’s Silicon Valley, and senior research scientist at the Planetary Science Institute in Tucson, Arizona. “That could be a fair way to picture it in your mind.” ![]() Left: Color-coded digital elevation model of the study area showing the two proposed shoreline levels of an early Mars ocean that existed approximately 3.4 billion years ago. Right: Areas covered by the documented tsunami events extending from these shorelines. (Alexis Rodriguez) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Reconnaissance Orbiter data reveals most recent Ice Age on MarsWritten by Guy Webster
The new results agree with previous models that indicate a glacial period ended about 400,000 years ago, as well as predictions about how much ice would have been accumulated at the poles since then. The results, published in the May 27th issue of the journal Science, help refine models of the Red Planet’s past and future climate by allowing scientists to determine how ice moves between the poles and mid-latitudes, and in what volumes. ![]() Climatic cycles of ice and dust build the Martian polar caps, season by season, year by year, and periodically whittle down their size when the climate changes. This image is a simulated 3-D perspective view, created from image data taken by the THEMIS instrument on NASA’s Mars Odyssey spacecraft. (NASA/JPL/Arizona State University, R.

NASA’s Cassini Spacecraft observes Enceladus plume brighten when farther away from SaturnWritten by Preston Dyches
The observation has led to a surprising new clue about the remarkable geologic activity on Enceladus: It appears that at least some of the narrow jets that erupt from the moon’s surface blast with increased fury when the moon is farther from Saturn in its orbit. ![]() The gravitational pull of Saturn changes the amount of particles spraying from the south pole of Saturn’s active moon Enceladus at different points in its orbit. More particles make the plume appear much brighter in the infrared image at left.

NASA studies Comet P/2016 BA14 as it passes by EarthWritten by DC Agle
The scientists used the Goldstone Solar System Radar in California’s Mojave Desert to track the comet. ![]() These radar images of comet P/2016 BA14 were taken on March 23, 2016, by scientists using an antenna of NASA’s Deep Space Network at Goldstone, California. At the time, the comet was about 2.2 million miles (3.6 million kilometers) from Earth. (NASA/JPL-Caltech/GSSR) «Read the rest of this article» Sections: Technology | No Comments
