Asteroid To Fly Safely Past Earth On April 19

Body Discovered Nearly Three Years Ago By Astronomers

A relatively large near-Earth asteroid discovered nearly three years ago will fly safely past Earth on April 19 at a distance of about 1.1 million miles, or about 4.6 times the distance from Earth to the moon. Although there is no possibility for the asteroid to collide with our planet, this will be a very close approach for an asteroid of this size.

Moon's Magnetic Field Lasted For About A Million Years, Scientists Say

The moon no longer has a magnetic field, but NASA scientists are publishing new research that shows heat from crystallization of the lunar core may have driven its now-defunct magnetic field some 3 billion years ago.

GMI Instrument Is The Calibration Standard For The Entire GPM Constellation To Improve Understanding Of Precipitation Patterns Around The World

The Global Precipitation Measurement (GPM) Microwave Imager (GMI), designed and built by Ball Aerospace for NASA's Goddard Space Flight Center, is entering its fourth year of service. Designed as a 3-year mission, GMI has performed successful operations on orbit while exceeding its performance requirements. The GPM spacecraft that hosts the GMI instrument is a joint effort between NASA and the Japan Aerospace Exploration Agency (JAXA) to provide frequent, near-global precipitation information critical for improving weather forecasting and protecting lives and property.
