On September 14th at 10.21 PM Kourou time (01.21 UTC; 03.21 AM CEST on September 15th), Avio will launch two Earth observation satellites: the Sentinel-3C of the Copernicus programme for the European Commission and the FLEX Earth Explorer for the European Space Agency (ESA). The mission, designated “VV30”, will be carried out by a Vega C launcher, the second operated by Avio, lifting off from the European Spaceport in French Guiana.
 
The satellites will be released into Sun-Synchronous Orbit at an altitude of about 820 km with an inclination of 98.6°. The duration of the launch (from lift-off to separation of the last satellite) is 116 minutes.
 
Copernicus Sentinel-3C is the third satellite of the Sentinel-3 mission, dedicated to monitoring the health of our planet by observing ocea...

ESA’s FLEX satellite and the Copernicus Sentinel-3C satellite are set to launch on 15 September at 03:21 CEST (14 September at 22:21 local time). Watch the launch programme live from Europe’s Spaceport in French Guiana, with streaming starting at 02:50 CEST and continuing until 05:36 CEST.

FLEX will provide new insights into how plants function by measuring the faint fluorescence they emit as they capture sunlight during photosynthesis. This unique measurement will help scientists better understand plant health and productivity, as well as how vegetation responds to a changing environment.

Sentinel-3C is the third satellite in the Sentinel-3 mission, which systematically monitors Earth’s oceans, land, ice and atmosphere. The mission as a whole contributes to a better understanding o...

Starlink Mission

Tranche 1 Transport Layer A is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites.

The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance.

This launch carries 21 satellites manufactured by Northrop Grumman.
