A carbon dioxide-mapping satellite tv for pc and four Earth-statement spacecraft launched efficiently tonight (July 25) from South The US.
A Vega C rocket, operated by the French company Arianespace, lifted off from Europe’s Spaceport in Kourou, French Guiana on agenda tonight at 10:03 p.m. EDT (11:03 p.m. local time in Kourou; 0203 GMT on July 26).
The four-stage, 115-foot-huge (35 meters) Vega C is carried 5 satellites on the mission, which Arianespace referred to as VV27.

One modified into once MicroCarb, a venture led by the French home company CNES. This 400-pound (180-kilogram) satellite tv for pc “is designed to scheme sources and sinks of carbon dioxide (CO2) — the biggest greenhouse gas — on a global scale,” CNES officers wrote in a mission description.
MicroCarb will doubtless be in a location to resolve CO2 concentrations with a precision of 1 section per million. The satellite tv for pc will feature in solar-synchronous orbit at an altitude of 404 miles (650 kilometers), for not not up to 5 years, if all goes to realizing.
The change four satellites will make up CNES’ CO3D (“Constellation Optique en 3D”) Earth-watching constellation. Each spacecraft in the quartet weighs about 550 pounds (250 kg) and may per chance maybe impartial soundless feature in solar-synchronous orbit at an altitude of 312 miles (502 km) for not not up to six years, in accordance to CNES.
The satellites, which had been built by Airbus, “have a unique optical instrument with a spatial resolution of approximately 50 cm [20 inches] in the red, green and blue visible bands and in the near-infrared,” CNES wrote in a mission description. “After processing on the ground, their data will yield 3D maps of all of Earth’s land surfaces between -60 degree and +70 degree latitudes.”

The CO3D satellites were deployed on agenda round 57 minutes after liftoff, and MicroCarb followed swimsuit 44 minutes later.
VV27 modified into once the fifth originate overall for the Vega C, and the third since an anomaly in the rocket’s 2d stage precipitated a mission failure in December 2022.
Potentially the most up to date three flights, counting tonight’s have all been a hit. The Vega C also lofted the Sentinel-1C Earth-statement satellite tv for pc and Biomass forest-monitoring spacecraft, each and each of them European Home Company missions, in December 2024 and April 2025, respectively.
