An Arianespace Vega-C rocket will launch the European Space Agency’s (ESA) Earth Explorer Biomass satellite into a Sun-synchronous orbit at an altitude of about 666 km (413.8 mi). Biomass features a P-band synthetic aperture radar (SAR) and is designed “to collect information on the height and structure of different forest types and measure the amount of carbon stored in the world’s forests and how it changes over time. In addition, the Biomass mission will map subsurface geology in deserts, the ice structure of ice sheets and the topography of forest floors.” This mission, also referred to as VV26, will be the fourth launch of a Vega-C rocket.
