NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover is continuing science observations while on the move this month. On April 16th, the mission passed 10 kilometers (6.214 miles) of total driving since its 2012 landing, including about a fifth of a mile (310 meters) so far this month.

The rover is trekking through a series of shallow valleys between the “Pahrump Hills” outcrop, which it investigated for six months, and the next science destination, “Logan Pass,” which is still about 200 yards, or meters, ahead toward the southwest.

NASA - National Aeronautics and Space AdministrationPasadena, CA – After spending more than a month in orbit on the dark side of dwarf planet Ceres, NASA’s Dawn spacecraft has captured several views of the sunlit north pole of this intriguing world. These images were taken on April 10th from a distance of 21,000 miles (33,000 kilometers), and they represent the highest-resolution views of Ceres to date.

Subsequent images of Ceres will show surface features at increasingly better resolution.

NASA’s Cassini spacecraft images reveals Tendril Structures coming from Saturn’s moon Enceladus

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Long, sinuous, tendril-like structures seen in the vicinity of Saturn’s icy moon Enceladus originate directly from geysers erupting from its surface, according to scientists studying images from NASA’s Cassini spacecraft.

This result is published online today in a study in the Astronomical Journal, along with additional insights into the nature of the structures.

“We’ve been able to show that each unique tendril structure can be reproduced by particular sets of geysers on the moon’s surface,” said Colin Mitchell, a Cassini imaging team associate at the Space Science Institute in Boulder, Colorado, and lead author of the paper.

This collage, consisting of two Cassini images of long, sinuous, tendril-like features from Saturn's moon Enceladus and two corresponding computer simulations of the same, illustrates how well the structures, and the sizes of the particles composing them, can be modeled by tracing the trajectories of tiny, icy grains ejected from Enceladus' south polar geysers.

NASA’s Spitzer Space Telescope discovers gas planet in the far reaches of the Milky Way Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known.

The discovery demonstrates that Spitzer — from its unique perch in space — can be used to help solve the puzzle of how planets are distributed throughout our flat, spiral-shaped Milky Way galaxy. Are they concentrated heavily in its central hub, or more evenly spread throughout its suburbs?

NASA’s Mars Curiosity rover measurements of Weather, Soil reveals possibility of Liquid Brine on Mars

 

Written by Guy Webster

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Martian weather and soil conditions that NASA’s Curiosity rover has measured, together with a type of salt found in Martian soil, could put liquid brine in the soil at night.

Perchlorate identified in Martian soil by the Curiosity mission, and previously by NASA’s Phoenix Mars Lander mission, has properties of absorbing water vapor from the atmosphere and lowering the freezing temperature of water. This has been proposed for years as a mechanism for possible existence of transient liquid brines at higher latitudes on modern Mars, despite the Red Planet’s cold and dry conditions.

NASA’s Cassini spacecraft data helps Scientists solve mystery behind Saturn’s Storms

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The long-standing mystery of why Saturn seethes with enormous storms every 30 years may have been solved by scientists working with data from NASA’s Cassini mission. The tempests, which can grow into bright bands that encircle the entire planet, are on a natural timer that is reset by each subsequent storm, the researchers report.

In 140 years of telescope observations, great storms have erupted on Saturn six times. Cassini and observers on Earth tracked the most recent of these storms from December 2010 to August 2011. During that time, the storm exploded through the clouds, eventually winding its way around Saturn.

This series of images from NASA's Cassini spacecraft shows the development of a huge storm of the type that erupts about every 30 years on Saturn. (NASA/JPL-Caltech/SSI)

NASA’s Dawn spacecraft creates Color Map of dwarf planet Ceres revealing a surface full of variety

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new color map of dwarf planet Ceres, which NASA’s Dawn spacecraft has been orbiting since March, reveals the diversity of the surface of this planetary body. Differences in morphology and color across the surface suggest Ceres was once an active body, Dawn researchers said today at the 2015 General Assembly of the European Geosciences Union in Vienna.

“This dwarf planet was not just an inert rock throughout its history. It was active, with processes that resulted in different materials in different regions. We are beginning to capture that diversity in our color images,” said Chris Russell, principal investigator for the Dawn mission, based at the University of California, Los Angeles.

This map-projected view of Ceres was created from images taken by NASA's Dawn spacecraft during its initial approach to the dwarf planet, prior to being captured into orbit in March 2015. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

NASA’s Hubble Space Telescope has made a name for itself in the past 25 years

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – You know you’ve made it when people know you by your first name alone.

There’s Cher. Beyoncé. Ozzie. Angelina. Lebron. Oprah.

Add to that list “Hubble.”

NASA’s Hubble Space Telescope is more than just a famous telescope. It is a household word, known to people of all walks of life, of all ages, and all levels of scientific literacy. Very few can compete with Hubble in name recognition, and its cultural impact is comparable to the Apollo moon landings.

NASA to begin study of microgravity’s effects on Bone Cells aboard International Space Station

NASA - National Aeronautics and Space AdministrationHouston, TX – Researchers may be “excyted” to learn that osteocyte cultures are headed to the International Space Station this spring for the first time. With their delivery on the next SpaceX commercial resupply services mission this month, the Osteocytes and mechano-transduction (Osteo-4) investigation team will analyze the effects of microgravity on this type of bone cell.

Understanding these effects will be critical as astronauts plan for future missions that require longer exposure to microgravity, such as to deep space or Mars.

NASA reports Crowdsourced Smartphone Data could give advance notice for People in Earthquake Zones

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Smartphones and other personal electronic devices could, in regions where they are in widespread use, function as early warning systems for large earthquakes, according to newly reported research.

This technology could serve regions of the world that cannot afford higher quality, but more expensive, conventional earthquake early warning systems, or could contribute to those systems.

The study, led by scientists at the U.S. Geological Survey (USGS), found that the sensors in smartphones and similar devices could be used to build earthquake warning systems.

Cell phones can detect ground motion and warn others before strong shaking arrives. ("Everyone Check Your Phones - NYC" by Jim Pennucci, used under CC BY.)
