NASA Radar Finds Ice Deposits at Moon’s North Pole

NASA Radar Finds Ice Deposits at Moon’s North Pole

Mini-SAR is a lightweight (less than 10 kg) imaging radar.  It uses the polarization properties of reflected radio waves to characterize surface properties.  Mini-SAR sends pulses of radar that are left-circular polarized.  Typical planetary surfaces reverse the polarization during the reflection of radio waves, so that normal echoes from Mini-SAR are right circular polarized.  The … Read more

NASA Awards Grants for Lunar Instrumentation

In this project, Dr. Cao and team will be developing a miniaturized, low-power, ultra-stable fluxgate magnetometer system for prolonged, uninterrupted operation on the lunar surface. The system incorporates a low-power, magnetically-clean thermal solution to achieve a temperature stability of 0.2 degrees Celsius at two distinct set-point temperatures, one for the lunar day and the other … Read more

NASA-Supported Team Discovers Aurora-Like Radio Bursts Above Sunspot

NASA-Supported Team Discovers Aurora-Like Radio Bursts Above Sunspot

“NASA’s growing heliophysics fleet is well suited to continue to investigate the source regions of these radio bursts,” said Natchimuthuk Gopalswamy, a heliophysicist and solar radio researcher at NASA’s Goddard Space Flight Center. “For example, the Solar Dynamics Observatory continually monitors the Sun’s active regions, which likely give rise to this phenomenon.” Source link

Total Solar Eclipse 2024: The Moon’s Moment in the Sun

Total Solar Eclipse 2024: The Moon’s Moment in the Sun

On April 8, 2024, much of North America will experience a solar eclipse: a cosmic alignment of Sun, Moon, and Earth, in that order. The Moon’s shadow path will make landfall on Mexico’s Pacific coast, cross the United States from Texas to Maine, and exit North America via Newfoundland, Canada, continuing into the Atlantic Ocean.  … Read more

NASA’s Global Precipitation Measurement Mission: 10 years, 10 stories – NASA Science

NASA’s Global Precipitation Measurement Mission: 10 years, 10 stories – NASA Science

A NASA-based team built a new tool to examine the risk of landslides. They developed a machine learning model that combines data on ground slope, soil moisture, snow, geological conditions, distance to faults, and the latest near real-time precipitation data from NASA’s IMERG product (part of the GPM mission). The model has been trained on … Read more

UNITE All-Nighter Delights Amateur Astronomers – NASA Science

UNITE All-Nighter Delights Amateur Astronomers – NASA Science

In mid-January, the UNITE team coordinated observations across Europe to catch the third-ever star-crossing event for a different planet. (The third one seen by humans, that is!) Once the team does catch it, they’ll know if it takes three Earth years to orbits its star, which would make it fairly cold planet, or something closer … Read more

2023 NASA International Space Apps Challenge Announces 10 Global Winners – NASA Science

2023 NASA International Space Apps Challenge Announces 10 Global Winners – NASA Science

The 2023 NASA Space Apps Challenge welcomed 57,999 registered participants, including space, science, technology, and storytelling enthusiasts of all ages. Participants came together from 152 countries and territories to celebrate a Year of Open Science with the theme of “Explore Open Science Together” in collaboration with NASA’s Transform to Open Science (TOPS). Teams used NASA … Read more

NASA Collaborating on European-led Gravitational Wave Observatory in Space – NASA Science

NASA Collaborating on European-led Gravitational Wave Observatory in Space – NASA Science

The LISA mission will enable observations of gravitational waves produced by merging supermassive black holes, seen here in a computer simulation. Most big galaxies contain central black holes weighing millions of times the mass of our Sun. When these galaxies collide, eventually their black holes do too. Download high-resolution video from NASA’s Scientific Visualization Studio. … Read more

Seeing and Believing: 15 Years of Exoplanet Images – NASA Science

Seeing and Believing: 15 Years of Exoplanet Images – NASA Science

Beta Pictoris is located about 60 light-years away toward the constellation of Pictor (the Painter’s Easel) and is one of the best-known examples of a star surrounded by a dusty debris disk. Earlier observations showed a warp of the disc, a secondary inclined disc and comets falling onto the star, all indirect, but tell-tale signs … Read more

AWE Launching to Space Station to Study Atmospheric Waves via Airglow – NASA Science

AWE Launching to Space Station to Study Atmospheric Waves via Airglow – NASA Science

“This is the first time that AGWs, especially the small-scale ones, will be measured globally at the mesopause, the gateway to the space,” said Michael Taylor, professor of physics at Utah State University and principal investigator for the mission. “More importantly, this is the first time we will be able to quantify the impacts of … Read more
