News 6 - NASA’s Magnetospheric Multiscale mission creates Guinness World Record
NASA scientists’ new discovery insight into Earth’s magnetosphere, has created Guinness world record for highest altitude fix of a GPS signal. Under Magnetospheric Multiscale mission, signal is fixed at 70000 kilometers above the surface of the Earth.
To complete such mission, scientists require four individual satellites that fly in a pyramid formation to map magnetic reconnection because GPS tracking allows the satellites to maintain a tight formation and obtain high resolution three-dimensional observations. The four MMS spacecraft required GPS measurements with accurate tracking systems and orbit calculations to guide tight flying formations.
News 7 - Water existence found on solar system’s largest metallic asteroid Psyche
Solar system’s largest metallic asteroid Psyche is found to have presence of water in a study published by Astronomical Journal. According to new observations by US Geological Survey and NASA, research was made using NASA Infrared Telescope Facility and found presence of water or hydroxyl on its surface which may be helpful in possible mechanisms of water molecules formation.
Psyche is made of pure nickel-iron metal, located in the asteroid belt and could be considered as a budding planet that was mostly destroyed by impacts billions of years ago.
