Sentinelle 2B, qui devrait \u00eatre lanc\u00e9 le 7 mars prochain, rejoindra son orbite gr\u00e2ce \u00e0 un lanceur Vega depuis le port spatial de l\u2019Europe \u00e0 Kourou (Guyane fran\u00e7aise). Ce lancement sera suivi avec attention par les \u00e9quipes du centre de contr\u00f4le de l\u2019ESA \u00e0 Darmstadt, en Allemagne.<\/p>\n<\/div>\n<p>Le satellite Sentinelle 2B va rejoindre Sentinelle 2A, son jumeau qui \u00e9volue d\u00e9j\u00e0 en orbite.
