Two European Earth-observing spacecraft launched from Kourou, French Guiana, on September 14. The Vega C rocket lifted off at 9:21 p.m. EDT, carrying the FLEX and Sentinel-3C satellites, which are set to deploy at an altitude of roughly 509 miles (820 kilometers).
FLEX Satellite
- Weight: 875 pounds (397 kg)
- Function: Monitors vegetation fluorescence, mapping plant photosynthetic activity, which is a first for satellites.
- Importance: Data will enhance understanding of the global carbon cycle and support agricultural management and food security amid rising population demands.
Sentinel-3C Satellite
- Weight: 2,520 pounds (1,143 kg)
- Role: Part of the Copernicus Earth-observation program, continuing the missions of the aging but operational Sentinel-3A and 3B satellites.
- Capabilities: Equipped with advanced instruments to measure Earth’s oceans, land, ice, and atmosphere, providing crucial near-real-time data for weather and ocean forecasting.
Vega C Rocket
- Height: 115 feet (35 meters)
- Launch History: Debuted in July 2022 with six successful flights prior to this mission.
- Operator: Originally developed by the European Space Agency and operated by Arianespace; now managed by the Italian company Avio.
The successful launch highlights the ongoing advancements in Earth observation technology and the importance of satellite data in addressing global challenges.
