About the Sentinel-3C & FLEX Mission
| Type | Earth Science |
|---|---|
| Orbit | Sun-Synchronous Orbit |
| Launch Cost | $48,000,000 |
Sentinel-3C is the third satellite in the Sentinel-3 constellation, which provides high-accuracy optical, radar and altimetry data for marine and land services.
The Fluorescence Explorer (FLEX) satellite is a part of ESA's Earth Explorer program. The satellite will map vegetation fluorescence to quantify photosynthetic activity.
Launch Pad & Location
Ariane Launch Area 1 (ELV)
Guiana Space Centre, French Guiana
| Launches | 55 |
|---|---|
| Orbital Launch Attempts | 55 |
| Total Launches | 335 |
The Guiana Space Centre is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located at a latitude of 5°. In operation since 1968, it is a suitable location for a spaceport because of its equatorial location and open sea to the east.
Avio S.p.A Vega-C Rocket
Vega-C is a single-body rocket nearly 35 m high with that weighs 210 tonnes on the launch pad. As with Vega, its main elements are three solid-propellant stages, an upper stage powered by a reignitable liquid-propellant engine and a payload fairing. Vega-C's P120C first stage replaces Vega’s smaller P80 to provide a significant increase in thrust at liftoff. It is also used as boosters (2 or 4) for the Ariane 6 rocket.
