It was third time lucky for Europe’s new Vega C rocket when it launched for its debut flight from Europe’s Spaceport in Kourou, French Guiana, on Wednesday (July 13) after a two-hour delay.
The rocket finally “jumped off the launched pad like a Jaguar racing car,” as launch commentators described it, at 9:13 a.m. EDT (1313 GMT; 10:13 a.m. local time in Kourou), at the very end of its two-hour launch window.Â
The automatic synchronized pre-launch sequence, which takes over the countdown four minutes before lift-off, halted the procedure twice earlier, first before the officially scheduled launch at 7:13 EDT (1113 GMT), then during a second attempt one hour later.Â
Once the 115-foot-tall (35 meters) medium-lift Vega C cleared the launch pad, everything continued without a hitch, including four burns of the Avum+ upper stage, an upgraded version of the one used on the original Vega rocket.Â

Vega C, developed by the European Space Agency (ESA) and operated by the French company Arianespace, is considerably more powerful than the original Vega, which has been flying since 2012.Â
In addition to the upgraded Avum upper stage, it sports brand new motors called P120C and Zefiro-40 in its first and second stage respectively.
Vega C can deliver 2.3 tons to a polar orbit around Earth, compared to 1.5 tons for the earlier Vega, ESA officials said in a statement (opens in new tab). Vega C also boasts about twice the payload-carrying volume of its predecessor, thanks to its larger fairing, ESA officials added.
“Vega C is well adapted for a broad range of missions, from nanosatellites to larger optical and radar observation spacecraft,” Arianespace representatives said in a description of the new rocket (opens in new tab). “Payload adapters will facilitate Vega C’s deployment of multiple satellite passengers, including configurations with primary payloads that are accompanied by cubesats or microsats.”
The debut mission displayed such diversity. The Vega C lofted seven satellites on Wednesday — one main spacecraft and six tiny, ride-along cubesats.
The chief payload was LARES-2, a 650-pound (295 kilograms) satellite developed by the Italian Space Agency.Â
“Once in orbit, LARES-2’s precise path will be tracked by laser, from ground stations,” ESA officials said in the same statement. “The purpose of the mission is to measure the so-called frame-dragging effect, a distortion of space-time caused by the rotation of a massive body such as Earth as predicted by Einstein’s general theory of relativity. Its predecessor, the similar LARES, was the main payload on the 2012 inaugural flight of Vega.”
One of the six cubesats will test a new way to detect biomolecules in space, while another will investigate plant growth in microgravity. A third aims to shed light on the auroras and other phenomena related to Earth’s magnetosphere, ESA officials said. The other three cubesats, including one developed by CERN, will study the effects of space radiation on electronics.
LARES-2 deployed into Earth orbit one hour and 24 minutes after liftoff. The six cubesats followed suit about an hour later.
Vega C’s debut was part of a busy stretch in spaceflight. The European booster lifted off less than five hours after Rocket Lab lofted a spy satellite for the U.S. National Reconnaissance Office, for example. And SpaceX plans to launch a robotic Dragon cargo capsule toward the International Space Station on Thursday evening (July 14).
Vega C joins the original Vega and the Ariane 5 heavy lifter in Arianespace’s rocket stable. The company is also developing another rocket, the Ariane 6, to replace the Ariane 5; the first flight of that powerful new rocket is expected in 2023.
Arianespace operated Russian-built Soyuz rockets until recently as well. But the partnership enabling such missions dissolved after Russia invaded Ukraine this past February.
