Heading north over the Atlantic Ocean, the Vega rocket’s first stage booster consumed its pre-packed solid propellant in two minutes, then jettisoned as the second stage’s solid-fueled motor ignited to continue the ascent into space. A third stage solid motor later ignited, then a hydrazine-fed reignitable fourth stage engine fired to precisely place the mission’s six satellite payloads into two distinct orbits.
The fourth stage deployed Airbus’s Pléiades Neo 3 remote sensing satellite into a polar orbit about 54 minutes after liftoff. After separating from the rocket at an altitude of 392 miles (632 kilometers), the Pléiades Neo 3 ...
