For Artemis astronauts traveling on missions to the Moon, two space weather instrument suites, NASA’s HERMES and ESA’s ERSA, will provide an early forecast. Weather in this case means energized, subatomic particles and electromagnetic fields hurtling through the solar system. ![]() Artist’s concept of the Gateway Power and Propulsion Element, or PPE, and Habitation and Logistics Outpost, or HALO, in orbit around the Moon. The gold box on the right side of the image depicts the HERMES payload. The ERSA payload is the silver box just below it. (NASA) «Read the rest of this article» Sections: Technology | No Comments

NASA’s MAVEN spacecraft studies Mars’ Atmosphere for causes of unpredictable Radio Communications disruptions
However, we do not fully understand them because they form at altitudes that are very difficult to explore at Earth. The unexpected discovery by MAVEN shows that Mars is a unique laboratory to explore and better understand this highly disruptive phenomenon. ![]() Graphic illustrating radio signals from a remote station (bent purple line) interfering with a local station (black tower) after being reflected off a plasma layer in the ionosphere.

NASA’s Juno Spacecraft discovers new Cyclone on Jupiter
The flyby also marked a victory for the mission team, whose innovative measures kept the solar-powered spacecraft clear of what could have been a mission-ending eclipse. ![]() A new, smaller cyclone can be seen at the lower right of this infrared image of Jupiter’s south pole taken on November 4th, 2019, during the 23rd science pass of the planet by NASA’s Juno spacecraft.

NASA’s Parker Solar Probe discovers new insights about our Sun
On December 4th, 2019, four new papers in the journal Nature describe what scientists have learned from this unprecedented exploration of our star — and what they look forward to learning next. «Read the rest of this article» Sections: Technology | No Comments
NASA launches Ionospheric Connection Explorer (ICON) spacecraft
A Northrop Grumman Stargazer L-1011 aircraft took off at 7:31pm CDT from Cape Canaveral Air Force Station in Florida carrying ICON, on a Northrop Grumman Pegasus XL rocket, to launch altitude of about 39,000 feet. ![]() Northrop Grumman’s L-1011 aircraft, Stargazer, prepares for takeoff at the Cape Canaveral Air Force Station Skid Strip in Florida on Oct. 10, 2019. Attached beneath the aircraft is the company’s Pegasus XL rocket, carrying NASA’s Ionospheric Connection Explorer (ICON). (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA’s original Artemis Mission studied interaction of Moon, Sun
Two robotic spacecraft orbiting the Moon today were initially known as ARTEMIS — short for Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun. Since 2011, these spacecraft have been sending scientists valuable information about the lunar environment, and laying groundwork critical to returning humans to the Moon. ![]() NASA’s twin ARTEMIS spacecraft have studied the solar wind’s interaction with the Moon, including the lunar wake that distorts nearby magnetic fields.

NASA selects Three Finalists for Future Small Satellites
The finalists include a 2022 robotic mission to study two asteroid systems, twin spacecraft to study the effects of energetic particles around Mars, and a lunar orbiter managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, to study water on the Moon. ![]() One of three finalists selected by NASA for future small satellites, Lunar Trailblazer will detect and map water on the lunar surface to study how its form, abundance and location relate to geology. The principal investigator is Caltech’s Bethany Ehlmann. JPL will provide project management. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s MAVEN Spacecraft to reduce Orbit around MarsNASA’s Goddard Space Flight Center
The operation will reduce the highest point of the MAVEN spacecraft’s elliptical orbit from 3,850 to 2,800 miles (6,200 to 4,500 kilometers) above the surface and prepare it to take on additional responsibility as a data-relay satellite for NASA’s Mars 2020 rover, which launches next year. “The MAVEN spacecraft has done a phenomenal job teaching us how Mars lost its atmosphere and providing other important scientific insights on the evolution of the Martian climate,” said Jim Watzin, director of NASA’s Mars Exploration Program. “Now we’re recruiting it to help NASA communicate with our forthcoming Mars rover and its successors.” ![]() Aerobraking plan for MAVEN. (left) Current MAVEN orbit around Mars: 6,200 kilometers (~3,850 miles) at highest altitude, and an orbit period of about 4.5 hours. (center) Aerobraking process: MAVEN performs a series of “deep dip” orbits approaching to within about 125 kilometers (~78 miles) of Mars at lowest altitude, causing drag from the atmosphere to slow down the spacecraft.

NASA studies elements that make a Stable Landslide into a disastrous oneWritten by Carol Rasmussen
For the first time, researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, and collaborating institutions have documented the transition of a stable, slow-moving landslide into catastrophic collapse, showing how drought and extreme rains likely destabilized the slide. ![]() The Mud Creek landslide in photographic image. The radar velocity map shows the pre-collapse (solid line) and post-collapse (dashed line) extent of the sliding area, with faster sliding velocities before the collapse shown in darker shades of red. The highest velocities were about 16 inches (40 centimeters) per year. (Google/SIO/NOAA/U.S. Navy/NGA/GEBCO/Landsat/Copernicus) «Read the rest of this article» Sections: Technology | No Comments
