social media users are invited to apply to attend our #NASASocial to see our Ice Cloud and land Elevation Satellite-2 (ICESat-2) laser instrument as it undergoes testing. Talk to scientists and engineers who work on laser missions and visit a laser-ranging facility at night to see green laser light pulses fired at satellites in space! A maximum of 50 active social media users will be selected to attend the one-day event on November 3 for an inside-the-gates experience at our Goddard Space Flight Center in Greenbelt, Maryland.
