Arianespace launched a new Earth observation satellite for Airbus along with four other tiny satellites. The VV19 Arianespace Vega rocket launched the Pléiades Neo 4 satellite and a quartet of cubesats from the Guiana Space Center in Kourou, French Guiana in South America.
The rocket carried Pléiades Neo 4 — the second of four very high-resolution satellites to launch as part of Airbus’ Pléiades Neo Earth-observing satellite constellation — and four cubesats, called BRO-4, SUNSTORM, LEDSAT and RADCUBE. All of the satellites, comprising a total payload of approximately 2,268 pounds (1,029 kilograms), were delivered into a sun-synchronous orbit, according to Arianespace.
Arianespace CEO Stéphane Israël said in a statement, “With this mission, Arianespace demonstrates yet again the incredible versatility of Vega. We delivered safely into orbit the second satellite of the innovative Pléiades Neo 4 constellation on behalf of Airbus, alongside 4 auxiliary cubesats for ESA [the European Space Agency] and the French start-up Unseenlabs.”
“In addition, their reactive tasking ability allows urgent acquisitions 30 to 40 minutes following request — which is five times higher than previous satellite constellations — and respond to the most critical situations in near real-time, [which is] very useful for natural disaster[s].”
Three of the four other spacecraft deployed by the Vega rocket belong to the European Space Agency (ESA) and one for Unseenlabs, a European satellite start-up. ESA’s three payloads include LEDSAT (or LED-based small SATellite), RADCUBE and SUNSTORM.
LEDSAT will test the use of Light Emitting Diodes (LEDs) to identify and track the satellites while in-orbit, even as RADCUBE will be used to demonstrate the use of small satellites for space weather monitoring, and SUNSTORM will use an innovative solar X-ray spectrometer to detect and characterize solar flares, or coronal mass ejections.
The final payload, BRO-4 (Breizh Reconnaissance Orbiter), is the fourth satellite of a maritime surveillance constellation operated by Unseenlabs. This nano-satellite constellation is designed to identify electromagnetic signals from space, allowing Unseenlabs to geolocate and characterize ships at sea. The company expects to launch between 20 and 25 nano-satellites for its constellation by 2025, according to the statement.
