An increasing frequency of computer resets on NASA's Mars Exploration Rover Opportunity has prompted the rover team to make plans to reformat the rover's flash memory.

The resets, including a dozen this month, interfere with the rover's planned science activities, even though recovery from each incident is completed within a day or two.

Flash memory retains data even when power is off. It is the type used for storing photos and songs on smart phones or digital cameras, among many other uses. Individual cells within a flash memory sector can wear out from repeated use. Reformatting clears the memory while identifying bad cells and flagging them to be avoided.

"Worn-out cells in the flash memory are the leading suspect in causing these resets," said John Callas of NASA's Jet Propulsion Laboratory, Pasadena, California, project manager for NASA's Mars Exploration Rover Project. "The flash reformatting is a low-risk process, as critical sequences and flight software are stored elsewhere in other non-volatile memory on the rover."

The project landed twin rovers Spirit and Opportunity on Mars in early 2004 to begin missions planned to last only three months. Spirit worked for six years, and Opportunity is still active. Findings about ancient wet environments on Mars have come from both rovers.

The project reformatted the flash memory on Spirit five years ago to stop a series of amnesia events Spirit had been experiencing. The reformatting planned for early next month will be the first for Opportunity. Even after the rover has been active for more than a decade and is currently about 125 million miles (about 200 million kilometers) from JPL, the rover team can still perform this type of upkeep.

Preparations include downloading to Earth all useful data remaining in the flash memory and switching the rover to an operating mode that does not use flash memory. Also, the team is restructuring the rover's communication sessions to use a slower data rate, which may add resilience in case of a reset during these preparations.

The Mars Exploration Rover Project is one element of NASA's ongoing and future Mars missions preparing for a human mission to the planet in the 2030s. JPL, a division of the California Institute of Technology, manages the project for NASA's Science Mission Directorate in Washington.

NASA Probes Studying Earth’s Radiation Belts to Celebrate Two Year Anniversary

NASA - Van Allen Probes logo.

August 29, 2014

NASA's twin Van Allen Probes will celebrate on Saturday two years of studying the sun’s influence on our planet and near-Earth space. The probes, shortly after launch in August 2012, discovered a third radiation belt around Earth when only two had previously been detected.

The radiation belts are layers of energetic charged particles held in place by the magnetic field surrounding our planet. The new third belt occurred only occasionally but persisted for as long as a month. This revealed to scientists the dynamic and variable nature of the radiation belts and provided new insight into how they respond to solar activity.

Image above: This image was created using data from the Relativistic Electron-Proton Telescopes on NASA's twin Van Allen Probes. It shows the emergence of a new third transient radiation belt. The new belt is seen as the middle orange and red arc of the three seen on each side of the Earth. Image Credit: APL, NASA.

"The primary science objective of the Van Allen Probes is to provide understanding of how particles in the radiation belts form and change in response to energy input from the sun," said Mona Kessel, the mission’s program scientist at NASA Headquarters in Washington.  "The discoveries and understanding gained have far exceeded expectations."

The probes, each weighing just less than 1,500 pounds, were specifically designed to withstand and study the harsh radiation belt region around Earth. The belts are critical regions that have a connection to Earth’s atmosphere and space-based technologies. The belts are affected by solar storms and space weather events and as a result, can swell dramatically. When this occurs, they can pose dangers to communications and GPS satellites, as well as humans in low-Earth orbit.

Formerly known as the Radiation Belt Storm Probes, the mission was renamed Van Allen Probes in November 2012 in honor of Dr. James Van Allen, who discovered the two radiation belts in 1958.

The twin spacecraft have also revealed how particles in the heart of the belts can be accelerated to nearly the speed of light; proven that electrons in the belts are undergoing acceleration from very low frequency plasma waves; and shown persistent stripe-like structures are a common feature of the inner belt, and are caused by Earth’s rotation, a mechanism previously thought to be incapable of such an effect.

Van Allen Probes

“The Van Allen Probes mission has given us the means to validate theories about plasma physics and the acceleration processes going on inside the belts,” said Barry Mauk, Van Allen Probes project scientist at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland. “They also have shown us new structures and features in this region of space, the existence of which we had never suspected. It has been a very illuminating two years, and we look forward to many more with these remarkable spacecraft.”

The Van Allen Probes are the second mission in NASA's Living With a Star (LWS) Program to explore aspects of the connected sun-Earth system that directly affect life and society. LWS is managed by the agency's Goddard Space Flight Center in Greenbelt, Maryland. APL built the spacecraft and manages the mission for the agency’s Science Mission Directorate in Washington.

Hubble Looks at Light and Dark in the Universe

NASA - Hubble Space Telescope patch.

Aug. 29, 2014

This new NASA/ESA Hubble Space Telescope image shows a variety of intriguing cosmic phenomena.

Surrounded by bright stars, towards the upper middle of the frame we see a small young stellar object (YSO) known as SSTC2D J033038.2+303212. Located in the constellation of Perseus, this star is in the early stages of its life and is still forming into a fully-grown star. In this view from Hubble’s Advanced Camera for Surveys(ACS) it appears to have a murky chimney of material emanating outwards and downwards, framed by bright bursts of gas flowing from the star itself. This fledgling star is actually surrounded by a bright disk of material swirling around it as it forms — a disc that we see edge-on from our perspective.

However, this small bright speck is dwarfed by its cosmic neighbor towards the bottom of the frame, a clump of bright, wispy gas swirling around as it appears to spew dark material out into space. The bright cloud is a reflection nebula known as [B77] 63, a cloud of interstellar gas that is reflecting light from the stars embedded within it. There are actually a number of bright stars within [B77] 63, most notably the emission-line star LkHA 326, and it nearby neighbor LZK 18.

These stars are lighting up the surrounding gas and sculpting it into the wispy shape seen in this image. However, the most dramatic part of the image seems to be a dark stream of smoke piling outwards from [B77] 63 and its stars — a dark nebula called Dobashi 4173. Dark nebulae are incredibly dense clouds of pitch-dark material that obscure the patches of sky behind them, seemingly creating great rips and eerily empty chunks of sky. The stars speckled on top of this extreme blackness actually lie between us and Dobashi 4173.

NASA Sees Massive Hurricane Marie

NASA / NOAA - GOES Mission logo.

August 28, 2014

Marie (Eastern Pacific)

When NOAA's GOES-West satellite captured an image of what is now Tropical Storm Marie, weakened from hurricane status on August 28, the strongest thunderstorms were located in the southern quadrant of the storm.

NOAA's GOES-West satellite captured an image of Marie on August 28 at 11 a.m. EDT. Bands of thunderstorms circled the storm especially to the north. The National Hurricane Center noted that Marie has continued to produce a small area of convection (rising air that forms the thunderstorms that make up Marie) south and east of the center during some hours on the morning of August 28. The GOES image was created by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Infrared data, such as that from the Atmospheric Infrared Sounder instrument aboard NASA's Aqua satellite showed that cloud tops had warmed. Warming cloud tops means that the strength in the uplift of air (that pushes cloud tops higher into the colder levels of the atmosphere) has weakened, and clouds are not getting as high as they did before. The higher the thunderstorms, the stronger they usually are, but Marie's are dropping in height.

Image above: This image of Tropical Storm Marie was captured by NOAA's GOES-West satellite on August 28 at 11 a.m. EDT and showed the strongest storms were south of the center. Image Credit: NASA/NOAA GOES Project.

Marie is not able to generate strong thunderstorms because it has moved over cooler waters. Sea surface temperatures of at least 80 F (26.6 C) are needed to maintain a hurricane's strength. Marie is in waters as cool as 22C (71.6F).

At 11 a.m. EDT (1500 UTC) Marie's maximum sustained winds were down to 45 mph (75 kph) and weakening. Marie was centered near latitude 25.4 north and longitude 128.9 west, about 865 miles (1,395 km) west of Punta Eugenia, Mexico. Marie is moving northwest at 15 mph (24 kph).

The NHC expects Marie should become post-tropical by tonight, August 28. Meanwhile Marie continues kicking up rough surf. Large southerly swells affecting much of the west coast of the Baja California peninsula and the coast of southern California will gradually subside through Friday, August 29. These swells could still produce life-threatening surf and rip currents, as well as minor coastal flooding around the time of high tide.

Researchers Use NASA and Other Data to Look Into the Heart of a Solar Storm

NASA / ESA - SOHO Mission patch.

August 28, 2014

Animation above: A coronal mass ejection on Jan. 20, 2005, produced an extreme amount of solar particles, seen as white static in this imagery from ESA/NASA's Solar and Heliospheric Observatory. Closer to Earth, it created a solar storm with an unusual combination of strong and weak effects. Image Credit: ESA/NASA/SOHO.

A space weather storm from the sun engulfed our planet on Jan. 21, 2005. The event got its start on Jan. 20, when a cloud of solar material, a coronal mass ejection or CME, burst off the sun and headed toward Earth. When it arrived at our planet, the ring current and radiation belts surrounding Earth swelled with extra particles, while the aurora persisted for six hours. Both of these are usually signs of a very large storm – indeed, this was one of the largest outpouring of solar protons ever monitored from the sun. But the storm barely affected the magnetic fields around Earth – disturbances in these fields can affect power grids on the ground, a potential space weather effect keenly watched for by a society so dependent on electricity.

Janet Kozyra, a space scientist at the University of Michigan in Ann Arbor, thought this intriguing combination of a simultaneously weak and strong solar storm deserved further scrutiny. In an effort to better understand -- and some day forecast -- such storms and their potential effects on human technology, an unusual event like this can help researchers understand just what aspects of a CME lead to what effects near Earth.

"There were features appearing that we generally only see during extreme space weather events, when by other measures the storm was moderate," said Kozyra. "We wanted to look at it holistically, much like terrestrial weather researchers do with extreme weather. We took every single piece of data that we could find on the solar storm and put it together to see what was going on."

Image above: Caption: A filament of cold dense solar material moved toward the front of a Jan. 20, 2005, coronal mass ejection, which led to an unusually large amount of solar material funneling into near-Earth space during a Jan. 21 solar storm. Image Credit: Janet Kozyra.

With observations collected from ground-based networks and 20 different satellites, Kozyra and a group of colleagues, each an expert in different aspects of the data or models, found that the CME contained a rare piece of dense solar filament material. This filament coupled with an unusually fast speed led to the large amount of solar material observed. A fortuitous magnetic geometry, however, softened the blow, leading to reduced magnetic effects. These results were published in the Aug. 14, 2014, issue of Journal of Geophysical Research, Space Physics.

The researchers gathered data from spacecraft orbiting in Earth's ionosphere, which extends up to 600 miles above the planet’s surface, and satellites above that, orbiting through the heart of Earth's magnetic environment, the magnetosphere. The massive amount of data was then incorporated into a variety of models developed at the University of Michigan’s Center for Space Environment Modeling, which are housed at the Community Coordinated Modeling Center at NASA's Goddard Space Flight Center in Greenbelt, Maryland, a facility dedicated to providing comprehensive access to space weather models.

With the models in hand, the team could put together the story of this particular solar storm. It began with the CME on Jan. 20, 2005. The European Space Agency and NASA's Solar and Heliospheric Observatory, or SOHO, captured images of the CME. At their simplest, CMEs look like a magnetic bubble with material around the outside. In this case, there was an additional line of colder, denser solar material – an electrically charged gas called plasma – inside called a solar filament. Solar filaments are ribbons of dense plasma supported in the sun’s outer atmosphere – the corona -- by strong magnetic fields. Filament material is 100 times denser and 100 times cooler than the surrounding atmosphere. When the supporting magnetic fields erupt, the filaments are caught up in the explosive release that forms the CME. Despite observations that the majority of eruptions like this involve solar filaments, the filaments are rarely identified in disturbances that reach Earth. Why this might be, is a mystery – but it means that the presence of the solar filament in this particular event is a rare sighting.

Image above: Twelve spacecraft in Earth’s magnetosphere – in addition to other missions -- helped scientists better observe and understand an unusual January 2005 solar storm. The four Cluster spacecraft were in the solar wind, directly upstream of Earth. Picture not to scale. Image Credit: ESA.

Subsequent observations of the CME showed it to be particularly fast, with a velocity that peaked at around 1800 miles per second before slowing to 600 miles per second as it approached Earth. Just how many CMEs have filaments or how the geometry of such filaments change as they move toward Earth is not precisely known. In this case, however, it seems that the dense filament sped forward, past the leading edge of the CME, so as it slammed into the magnetosphere, it delivered an extra big dose of energetic particles into near-Earth space.

What happened next was observed by a flotilla of Earth-orbiting scientific satellites, including NASA's IMAGE, FAST and TIMED missions, the joint European Space Agency, or ESA, and NASA's Cluster, the NASA and ESA's Geotail, the Chinese and ESA's Double Star-1; other spacecraft 1 million miles closer to the sun including SOHO and NASA's Advanced Composition Explorer, Wind various other spacecraft; as well as the National Science Foundation-supported ground-based SuperDARN radar network. At the time Cluster was in the solar wind directly upstream of Earth. Meanwhile, Double Star-1 was passing from the outer region of the planet’s magnetic field and entering the magnetosphere. This enabled it to observe the entry of the solar filament material as it crossed into near-Earth space.

“Within one hour of the impact, a cold, dense plasma sheet formed out of the filament material," said Kozyra. "High density material continued to move through the magnetosphere for the entire six hours of the filament’s passage."

Despite the intense amount of plasma carried by the CME, it still lacked a key component of a super storm. The magnetic fields embedded in this CME generally pointed toward Earth's north pole, just as Earth's own magnetic fields do. This configuration causes far fewer disruptions to our planet's system than when the CME's fields point southward. When pointing south, the CME's fields clash with Earth's, peeling them back and setting off magnetic perturbations that cascade through the magnetosphere.

The magnetic field orientation is what kept this solar storm to low levels. On the other hand, the extra solar material from the filament catalyzed long-term aurora over the poles and enhanced the particle filled radiation belts around Earth, characteristic of a larger storm.

"This event, with its unusual combination of space weather effects really demonstrates why it's important to look at the entire system, not just individual elements," said Kozyra. "Only by using all of this data, by watching the event from the beginning to the end, can we begin to understand all the different facets of an extreme storm like this."

Understanding what created the facets of this particular 2005 storm adds to a much larger body of knowledge about how different kinds of CMEs can affect us here at Earth. By knowing what factors lead to the total strength of a storm, we can better learn to predict what the sun is sending our way.

NASA's Spitzer Telescope Witnesses Asteroid Smashup

NASA - Spitzer Space Telescope patch.

August 28, 2014

NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets.

Scientists had been regularly tracking the star, called NGC 2547-ID8, when it surged with a huge amount of fresh dust between August 2012 and January 2013.

"We think two big asteroids crashed into each other, creating a huge cloud of grains the size of very fine sand, which are now smashing themselves into smithereens and slowly leaking away from the star," said lead author and graduate student Huan Meng of the University of Arizona, Tucson.

Image above: This artist’s concept shows the immediate aftermath of a large asteroid impact around NGC 2547-ID8, a 35-million-year-old sun-like star. NASA's Spitzer Space Telescope witnessed a giant surge in dust around the star, likely the result of two asteroids colliding. Image Credit: NASA/JPL-Caltech.

While dusty aftermaths of suspected asteroid collisions have been observed by Spitzer before, this is the first time scientists have collected data before and after a planetary system smashup. The viewing offers a glimpse into the violent process of making rocky planets like ours.

Rocky planets begin life as dusty material circling around young stars. The material clumps together to form asteroids that ram into each other. Although the asteroids often are destroyed, some grow over time and transform into proto-planets. After about 100 million years, the objects mature into full-grown, terrestrial planets. Our moon is thought to have formed from a giant impact between proto-Earth and a Mars-size object.

In the new study, Spitzer set its heat-seeking infrared eyes on the dusty star NGC 2547-ID8, which is about 35 million years old and lies 1,200 light-years away in the Vela constellation. Previous observations had already recorded variations in the amount of dust around the star, hinting at possible ongoing asteroid collisions. In hope of witnessing an even larger impact, which is a key step in the birth of a terrestrial planet, the astronomers turned to Spitzer to observe the star regularly. Beginning in May 2012, the telescope began watching the star, sometimes daily.

A dramatic change in the star came during a time when Spitzer had to point away from NGC 2547-ID8 because our sun was in the way. When Spitzer started observing the star again five months later, the team was shocked by the data they received.

"We not only witnessed what appears to be the wreckage of a huge smashup, but have been able to track how it is changing -- the signal is fading as the cloud destroys itself by grinding its grains down so they escape from the star," said Kate Su of the University of Arizona and co-author on the study. "Spitzer is the best telescope for monitoring stars regularly and precisely for small changes in infrared light over months and even years."

Image above: Astronomers were surprised to see these data from NASA's Spitzer Space Telescope in January 2013, showing a huge eruption of dust around a star called NGC 2547-ID8. In this plot, infrared brightness is represented on the vertical axis, and time on the horizontal axis. Image Credit: NASA/JPL-Caltech/University of Arizona.

A very thick cloud of dusty debris now orbits the star in the zone where rocky planets form. As the scientists observe the star system, the infrared signal from this cloud varies based on what is visible from Earth. For example, when the elongated cloud is facing us, more of its surface area is exposed and the signal is greater. When the head or the tail of the cloud is in view, less infrared light is observed. By studying the infrared oscillations, the team is gathering first-of-its-kind data on the detailed process and outcome of collisions that create rocky planets like Earth.

"We are watching rocky planet formation happen right in front of us," said George Rieke, a University of Arizona co-author of the new study. "This is a unique chance to study this process in near real-time."

The team is continuing to keep an eye on the star with Spitzer. They will see how long the elevated dust levels persist, which will help them calculate how often such events happen around this and other stars, and they might see another smashup while Spitzer looks on.

Robonaut Gets New Legs as Trio Prepares for Homecoming

ISS - Expedition 40 Mission patch.

August 27, 2014

Expedition 40 participated in health checks, Robonaut upgrades and Soyuz emergency drills Wednesday. The International Space Station also boosted its orbit setting the stage for a crew departure and arrival in September.

Commander Steve Swanson joined Flight Engineer Reid Wiseman and Alexander Gerst for health checks during the morning. The trio checked each other’s blood pressure and temperature as part of their clinical exams.

Swanson then moved on to more Robonaut mobility upgrade activities throughout the day. The commander reviewed his upgrade tasks and set up cameras so ground controllers could view his installation work on the humanoid robot.

Robonaut 2 is receiving new legs that will enable it to move inside and outside the space station. More upper body upgrades are scheduled for the end of 2014 before Robonaut will be ready to conduct its first spacewalk. Robonaut was designed to enhance crew productivity and safety while also aiding people on Earth with physical disabilities.

Space Station Live: Robonaut Mobility Upgrades

Wiseman and Swanson got together in the afternoon for a call with students from Elliot Ranch Elementary School in Elk Grove, Calif. The NASA astronaut duo answered basic questions about living and working in space.

Before the student call Wiseman joined his Soyuz crewmates cosmonaut Max Suraev and German astronaut Alexander Gerst for an emergency drill. They practiced their responsibilities in the unlikely event of an emergency such as a pressure leak which would require the crew to undock from the station and return home in its Soyuz lifeboat.

Gerst, a European Space Agency astronaut, spent a few minutes after his health exam on the VIABLE microbiology experiment. He was inside the Zarya cargo module checking experimental materials in a locker panel. The study seeks to maintain crew member health and prevent damage and contamination to space station hardware.

Read more about VIABLE: http://www.nasa.gov/mission_pages/station/research/experiments/806.html

Gerst then moved on to LAN cable maintenance in the Columbus lab module. After that work, he went inside the cupola and photographed its windows with the shutters closed to determine if any hardware might interfere with upcoming IMAX work.

Returning cosmonauts Alexander Skvortsov and Oleg Artemyev called down to specialists Wednesday morning to discuss search and rescue operations when they land in Kazakhstan. The duo, who conducted Soyuz departure preparations throughout the morning, will be joined by Swanson when they leave the station and undock from the Poisk docking compartment in their Soyuz TMA-12M spacecraft Sept. 10 ending Expedition 40.

Europe’s “Georges Lemaître” Automated Transfer Vehicle (ATV-5) fired its engines early in the morning slightly raising the station’s orbit while docked to the Zvezda service module. The reboost readies the Soyuz carrying the Expedition 40 trio home in two weeks. The orbital laboratory will also be in the proper phasing for the arrival of the Expedition 41 trio in its Soyuz TMA-14M spacecraft on Sept. 25.

The new Expedition 41 trio is composed of two veteran space-flyers, NASA astronaut Barry Wilmore, Soyuz Commander Alexander Samoukutyaev and new cosmonaut Elena Serova. They will take a near six-hour, or four-orbit, ride to the space station’s Poisk module. They are scheduled to return to Earth March 2015.
