NASA along with European Space Agency observe how Solar Storms move through Space

 

Written by Sarah Frazier
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Our Sun is active: Not only does it release a constant stream of material, called the solar wind, but it also lets out occasional bursts of faster-moving material, known as coronal mass ejections, or CMEs.

NASA researchers wish to improve our understanding of CMEs and how they move through space because they can interact with the magnetic field around Earth, affecting satellites, interfering with GPS signals, triggering auroras, and — in extreme cases — straining power grids.

While we track CMEs with a number of instruments, the sheer size of the solar system means that our observations are limited, and usually taken from a distance.

ESA and NASA’s Solar and Heliospheric Observatory observed a coronal mass ejection erupting from the Sun on Oct. 14, 2014. Scientists went on to track this coronal mass ejection through the solar system using 10 NASA and ESA spacecraft. (The bright light appearing at roughly 2 o'clock is the planet Mercury.)

NASA’s Eclipse Balloon Project to simulate life’s ability to survive beyond Earth

 

Written by Andrew Good
NASA’ Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Steps forward in the search for life beyond Earth can be as simple as sending a balloon into the sky. In one of the most unique and extensive eclipse observation campaigns ever attempted, NASA is collaborating with student teams across the U.S. to do just that.

A larger initiative, NASA’s Eclipse Balloon Project, led by Angela Des Jardins of Montana State University, is sending more than 50 high-altitude balloons launched by student teams across the U.S. to livestream aerial footage of the August 21st, 2017, total solar eclipse from the edge of space to NASA’s website.

This picture of Montana was taken from the stratosphere (84,000 feet or 25,000 meters) during one of Montana Space Grant Consortium's high-altitude balloon tests on April 19, 2014. (Montana State University)

NASA’s Mars Rover Opportunity takes panoramic photo from Perseverance Valley

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Exploration Rover Opportunity recorded a panoramic view before entering the upper end of a fluid-carved valley that descends the inner slope of a large crater’s rim.

The scene includes a broad notch in the crest of the crater’s rim, which may have been a spillway where water or ice or wind flowed over the rim and into the crater. Wheel tracks visible in the area of the notch were left by Opportunity as the rover studied the ground there and took images into the valley below for use in planning its route.

This June 2017 view from the Pancam on NASA's Opportunity Mars rover shows the area just above "Perseverance Valley" on a large crater's rim. A broad notch in the crest of the rim, at right, might have been a spillway for a fluid that carved the valley, out of sight on the other side of the rim. (NASA)

NASA reports Limited Communications between Earth and Mars due to Sun this month

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – This month, movements of the planets will put Mars almost directly behind the sun, from Earth’s perspective, causing curtailed communications between Earth and Mars.

NASA will refrain from sending commands to America’s three Mars orbiters and two Mars rovers during the period from July 22nd to August 1st, 2017.

“Out of caution, we won’t talk to our Mars assets during that period because we expect significant degradation in the communication link, and we don’t want to take a chance that one of our spacecraft would act on a corrupted command,” said Chad Edwards, manager of the Mars Relay Network Office at NASA’s Jet Propulsion Laboratory, Pasadena, California.

NASA’s Mars Curiosity Rover starts investigating Mars Ridge containing Hematite

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The car-size NASA rover on a Martian mountain, Curiosity, has begun its long-anticipated study of an iron-bearing ridge forming a distinctive layer on the mountain’s slope.

Since before Curiosity’s landing five years ago next month, this feature has been recognized as one of four unique terrains on lower Mount Sharp and therefore a key mission destination. Curiosity’s science team informally named it “Vera Rubin Ridge” this year, commemorating astronomer Vera Cooper Rubin (1928-2016).

“Our Vera Rubin Ridge campaign has begun,” said Curiosity Project Scientist Ashwin Vasavada of NASA’s Jet Propulsion Laboratory, Pasadena, California. “Curiosity is driving parallel to the ridge, below it, observing it from different angles as we work our way toward a safe route to the top of the ridge.”

This early 2017 look ahead from the Mastcam of NASA's Curiosity Mars rover includes four geological layers to be examined by the mission, and higher reaches of Mount Sharp beyond the planned study area. (NASA/JPL-Caltech/MSSS)

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Vice President Mike Pence thanked employees at NASA’s Kennedy Space Center in Florida for their commitment to America’s continued leadership in the space frontier during a visit to America’s multi-user spaceport on Thursday.

“Let us do what our nation has always done since its very founding and beyond: We’ve pushed the boundaries on frontiers, not just of territory, but of knowledge. We’ve blazed new trails, and we’ve astonished the world as we’ve boldly grasped our future without fear,” the Vice President told employees, government dignitaries and space industry leaders in remarks at the facility’s iconic Vehicle Assembly Building, where the new Space Launch System (SLS) rocket and Orion spacecraft will be prepared ahead of launches to the moon, and eventually to Mars and beyond.

NASA’s Pathfinder Lander ignited 20 years of Mars Exploration

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As the Mars Pathfinder spacecraft approached its destination on July 4th, 1997, no NASA mission had successfully reached the Red Planet in more than 20 years.

Even the mission team anxiously awaiting confirmation that the spacecraft survived its innovative, bouncy landing could not anticipate the magnitude of the pivot about to shape the Space Age.

In the 20 years since Pathfinder’s touchdown, eight other NASA landers and orbiters have arrived successfully, and not a day has passed without the United States having at least one active robot on Mars or in orbit around Mars.

NASA uses Algorithm to protect Wheels on Mars Curiosity Rover

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – There are no mechanics on Mars, so the next best thing for NASA’s Curiosity rover is careful driving.

A new algorithm is helping the rover do just that. The software, referred to as traction control, adjusts the speed of Curiosity’s wheels depending on the rocks it’s climbing. After 18 months of testing at NASA’s Jet Propulsion Laboratory in Pasadena, California, the software was uploaded to the rover on Mars in March. Mars Science Laboratory’s mission management approved it for use on June 8th, after extensive testing at JPL and multiple tests on Mars.

Even before 2013, when the wheels began to show signs of wear, JPL engineers had been studying how to reduce the effects of the rugged Martian surface.

NASA’s Cassini Spacecraft’s 20 Year Mission to come to a close

 

Written by Steven Siceloff
NASA’s Kennedy Space Center

NASA - National Aeronautics and Space AdministrationFlorida – As NASA’s Cassini spacecraft spends its last few weeks in orbit around Saturn before making a controlled impact with the planet in what NASA dubbed Cassini’s “Grand Finale,” some of those who helped launch the mission 20 years ago are thrilled with the success of the massive probe they helped dispatch to one of the solar system’s most intriguing worlds.

“There’s just a real sense of fulfillment associated with being part of a launch team, particularly something as big as Cassini and as complicated as Cassini is and the whole makeup of the whole Cassini team,” said Ray Lugo, launch director for Cassini. “It was a big community of folks and everybody had to do their part to make sure that mission got off right.”
