An Ariane 6 rocket from Arianespace will launch EUMETSAT’s MetOp-SG A1 (MetOp Second Generation) satellite to a polar orbit at an altitude of 832 km (517 mi). The satellite also carries the Copernicus Sentinel-5 satellite onboard. This is the first in a series of six satellites scheduled to be launched between now and 2040. These MetOp satellites weigh more than 4,000 kg (8,819 lbs) each and is about the size of a small truck. This will be the third launch of an Ariane 6 rocket.
