NASA’s Cassini spacecraft observes Saturn’s moon Titan in the Solar Wind

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers studying data from NASA’s Cassini mission have observed that Saturn’s largest moon, Titan, behaves much like Venus, Mars or a comet when exposed to the raw power of the solar wind. The observations suggest that unmagnetized bodies like Titan might interact with the solar wind in the same basic ways, regardless of their nature or distance from the sun.

Titan is large enough that it could be considered a planet if it orbited the sun on its own, and a flyby of the giant moon in December 2013 simulated that scenario, from Cassini’s vantage point.

Volunteers scanning NASA’s Spitzer Space Telescope images lead Astronomers to new Discovery

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Sometimes it takes a village to find new and unusual objects in space. Volunteers scanning tens of thousands of starry images from NASA’s Spitzer Space Telescope, using the Web-based Milky Way Project, recently stumbled upon a new class of curiosities that had gone largely unrecognized before: yellow balls.

The rounded features are not actually yellow — they just appear that way in the infrared, color-assigned Spitzer images.

Volunteers using the web-based Milky Way Project brought star-forming features nicknamed "yellowballs" to the attention of researchers, who later showed that they are a phase of massive star formation. (NASA/JPL-Caltech)

NASA’s Dawn Spacecraft takes sharpest picture yet of dwarf planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Dawn spacecraft has returned the sharpest images ever seen of the dwarf planet Ceres. The images were taken 147,000 miles (237,000 kilometers) from Ceres on January 25th, and represent a new milestone for a spacecraft that soon will become the first human-made probe to visit a dwarf planet.

“We know so little about our vast solar system, but thanks to economical missions like Dawn, those mysteries are being solved,” said Jim Green, Planetary Science Division Director at NASA Headquarters in Washington.

This animation of the dwarf planet Ceres was made by combining images taken by the Dawn spacecraft on January 25th, 2015.

NASA’s Deep Space Network antenna image shows Asteroid passing Earth today had it’s own Moon

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists working with NASA’s 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California, have released the first radar images of asteroid 2004 BL86. The images show the asteroid, which made its closest approach today (January 26th, 2015) at 8:19am PST (10:19am CST) at a distance of about 745,000 miles (1.2 million kilometers, or 3.1 times the distance from Earth to the moon), has its own small moon.

The 20 individual images used in the movie were generated from data collected at Goldstone on January 26th, 2015. They show the primary body is approximately 1,100 feet (325 meters) across and has a small moon approximately 230 feet (70 meters) across.

NASA reports future Mars Rovers could have Helicopter Scout

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Getting around on Mars is tricky business. Each NASA rover has delivered a wealth of information about the history and composition of the Red Planet, but a rover’s vision is limited by the view of onboard cameras, and images from spacecraft orbiting Mars are the only other clues to where to drive it.

To have a better sense of where to go and what’s worth studying on Mars, it could be useful to have a low-flying scout.

A proposed helicopter could triple the distances that Mars rovers can drive in a Martian day and help pinpoint interesting targets for study. (NASA)

NASA’s Mars Opportunity Rover celebrates it’s 11th Anniversary on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A panorama from one of the highest elevations that NASA’s Mars Exploration Rover Opportunity has reached in its 11 years on Mars includes the U.S. flag at the summit.

The view is from the top of “Cape Tribulation,” a raised section of the rim of Endeavour Crater. The panorama spans the interior of the 14-mile-wide (22-kilometer-wide) crater and extends to the rim of another crater on the horizon.

Opportunity has driven 25.9 miles (41.7 kilometers) since it landed in the Meridiani Planum region of Mars on January 25th, 2004 (Universal Time, which was January 24th, PST).

This panorama is the view NASA's Mars Exploration Rover Opportunity gained from the top of the "Cape Tribulation" segment of the rim of Endeavour Crater. (NASA/JPL-Caltech/Cornell Univ./Arizona State Univ.)

NASA’s Dawn spacecraft data shows evidence that Vesta may have had Water at one time

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Protoplanet Vesta, visited by NASA’s Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its surface.

However, a new study shows evidence that Vesta may have had short-lived flows of water-mobilized material on its surface, based on data from Dawn.

“Nobody expected to find evidence of water on Vesta. The surface is very cold and there is no atmosphere, so any water on the surface evaporates,” said Jennifer Scully, postgraduate researcher at the University of California, Los Angeles. “However, Vesta is proving to be a very interesting and complex planetary body.”

NASA’s Microwave Instrument aboard Rosetta Orbiter shows Comet now spewing Water into Space

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – There has been a significant increase in the amount of water “pouring” out of comet 67P/Churyumov-Gerasimenko, the comet on which the Rosetta mission’s Philae lander touched down in November 2014.

The 2.5-mile-wide (4-kilometer) comet was releasing the earthly equivalent of 40 ounces (1.2 liters) of water into space every second at the end of August 2014. The observations were made by NASA’s Microwave Instrument for Rosetta Orbiter (MIRO), aboard the European Space Agency’s Rosetta spacecraft. Science results from the MIRO team were released today as part of a special Rosetta-related issue of the journal Science.

This animation comprises 24 montages based on images acquired by the navigation camera on the European Space Agency's Rosetta spacecraft orbiting Comet 67P/Churyumov-Gerasimenko between Nov. 19 and Dec. 3, 2014. (ESA/Rosetta/NAVCAM)

NASA and Microsoft work together on new technology to let Scientists work Virtually on Mars

 

Written by Guy Webster/Veronica McGregor
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens.

Developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, OnSight will give scientists a means to plan and, along with the Mars Curiosity rover, conduct science operations on the Red Planet.

NASA’s Dawn spacecraft captures photo of dwarf planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As NASA’s Dawn spacecraft closes in on Ceres, new images show the dwarf planet at 27 pixels across, about three times better than the calibration images taken in early December. These are the first in a series of images that will be taken for navigation purposes during the approach to Ceres.

Over the next several weeks, Dawn will deliver increasingly better and better images of the dwarf planet, leading up to the spacecraft’s capture into orbit around Ceres on March 6th. The images will continue to improve as the spacecraft spirals closer to the surface during its 16-month study of the dwarf planet.

This processed image, taken Jan. 13, 2015, shows the dwarf planet Ceres as seen from the Dawn spacecraft. The image hints at craters on the surface of Ceres. Dawn's framing camera took this image at 238,000 miles (383,000 kilometers) from Ceres. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)
