"description": "One of the biggest questions in planetary science is whether life ever arose on Mars, and NASA and the European Space Agency are sending a cutting-edge instrument to the red planet to find out. The Mars Organic Molecule Analyzer, or MOMA, is a sophisticated suite of technologies that squeezes a lab full of chemistry equipment into a package the size of a toaster. MOMA will travel to Mars aboard ESA's Rosalind Franklin rover (formerly ExoMars), where it will search for evidence of past or present life.\r\r
MOMA will not only search for organic molecules, which make up all life on Earth, it will also analyze their structure using its linear ion trap – the first use of this technology on Mars. Doing so will help scientists to determine whether the molecules could be of biological origin, a significant leap forward in the search for life beyond Earth.\r\r
MOMA's mass spectrometer subsystem and main electronics were built at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The pulsed UV laser and high-temperature ovens were developed in Germany, and the gas chromatograph in France. The Rosalind Franklin rover is a component of ExoMars, the primary Mars exploration program of the European Space Agency. \r\r

"title": "What Mercury’s Unusual Orbit Reveals About the Sun",
"description": "Mercury is special. As the closest planet to the Sun, it occupies a region where the Sun’s influence is changing dramatically. The Sun’s magnetic field, which dominates space close to the Sun, is rapidly waning. And Mercury’s orbit – more elliptical or “oval-shaped” than any other planet – allows it to experience a wider range of solar magnetic field conditions than any other planet. As a result, Mercury provides a unique opportunity to study how the Sun’s influence on a planet varies with distance.In a new study published in Nature Communications, Goddard scientists Norberto Romanelli and Gina DiBraccio used data from NASA’s MESSENGER spacecraft to study the Sun’s changing interaction with Mercury. As Mercury moves through the solar wind, the steady stream of particles escaping the Sun, some of them strike Mercury’s magnetosphere and bounce back towards the Sun. These rebounding solar wind particles generate low-frequency waves that reverberate through space, traveling “upstream” in the solar wind towards the Sun. Romanelli and DiBraccio observed these waves emanating from Mercury and discovered that the rate of wave production varied throughout Mercury’s orbit. As Mercury moved farther from the Sun it generated more waves; as it got closer, the rate of wave production dropped. The results provide key evidence for a theory that these waves are affected, in part, by the strength of the Sun’s magnetic field, which grows weaker with distance. || ",
