  • ESA’s future Lagrange mission to monitor the Sun

    ESA’s future Lagrange mission to monitor the Sun

    Space weather describes the changing environment throughout the Solar System, driven by the energetic and unpredictable nature of our Sun. Solar wind, solar flares and Coronal Mass Ejections can result in geomagetic storms on Earth, potentially damaging satellites in space and the technologies that rely on them, as well as infrastructure on the ground.

    ESA’s future Lagrange mission will keep constant watch on the Sun. The satellite, located at the fifth Lagrange point, will send early warning of potentially harmful solar activity before it affects satellites in orbit or power grids on the ground, giving operators the time to act to protect vital infrastructure.

    ESA is now working with European industry to assess options for the spacecraft and its mission, with initial proposals expected early in 2020.

    NASA Celebrates MESSENGER Mission Prior to Surface Impact on Planet Mercury

    NASA held a panel discussion media on Thursday, April 16, to share scientific findings and technical accomplishments of the agency’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft.

    After more than 10 years in space, the highly successful mission will come to an end when it is expected to collide into planet Mercury at a speed of more than 8,750 miles per hour (3.91 km/sec) near the end of this month.

    Launched in August 2004, MESSENGER traveled 4.9 billion miles (7.9 billion kilometers) – a journey that included 15 trips around the sun and flybys of Earth once, Venus twice, and Mercury three times – before it was inserted into orbit around its target planet in March 2011. The spacecraft’s cameras and other sophisticated, high-technology instruments have collected unprecedented images and made other observations. Mission managers are preparing to impact Mercury’ surface in the next couple weeks.

    Participants featured were:

    · James Green, director, Planetary Science Division, NASA Headquarters, Washington
    · Sean Solomon, MESSENGER principal investigator; director, Columbia University’s Lamont-Doherty Earth Observatory, Palisades, New York
    · Helene Winters, MESSENGER project manager, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland
    · Daniel O’Shaughnessy, MESSENGER systems engineer, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland
