Launch of Sentinel 2 B on March 6th

Sentinel -2B

Launch of the Sentinel 2 B satellite 


  • After the launch of the Guiana Space Center, the motor phase of the first three stages of Vega will last 6 minutes, 32 seconds.
  • After this first phase, the third stage of the launcher will separate from the upper composite.
  • Which includes the upper stage AVUM, a payload adapter and the satellite.
  • The three lower stages will fall into the sea.
  • The upper stage AVUM switches on its engine for the first time, operating for about 7 minutes.
  • Followed by a ballistic phase of about 40 minutes.
  • The AVUM stage will then restart its motor for about 2 minutes.
  • Before releasing the Sentinel-2B satellite about one minute after the engine stops.Sentinel 2 B


  • Sentinel-2B will serve a wide range of terrestrial surface and coastal zone applications.
  • This mission provides information on agricultural and forestry practices.
  • To help manage food security.
  • Satellite images will be used to determine various plant indices
  • Such as the chlorophyll content of the leaf area and the water content indices.
  • This is particularly important for efficient prediction of yield and applications
  • And related to the vegetation of the Earth.
  • In addition to monitoring plant growth, Sentinel-2 can be used to map changes in soil cover.
  • And to monitor the world’s forests.

    Examples of applications:

  • Monitoring of land cover change for environmental monitoring.
  • Agricultural applications, such as crop monitoring and management to support food security.
  •  Detailed monitoring of vegetation and forests and generation of parameters eg: leaf area index, chlorophyll concentration, carbon mass estimates.
  •  Observation of coastal areas monitoring of the marine environment, mapping of coastal areas.
  • Inland water monitoring.
  • Monitoring of glaciers, mapping of ice extent, monitoring of snow cover.
  •  Flood management and mapping ,risk analysis, loss assessment, disaster management during floods.
  • The Sentinel Monitoring Web application provides a simple way to view.
  • And analyze land changes based on archived Sentinel-2 data.

Date and time of launch:

  • Date                :                March 6, 2017.
  • Time               :                10:49:24 pm, local time in French Guiana.
  • Location         :                Vega Launch Complex (SLV) in Kourou, French Guiana.
