The Final Vega Rocket Launch

On September 5, 2024, the European Space Agency (ESA) bid farewell to its Vega rocket, concluding an era of reliable and efficient space missions. The final flight of Vega successfully deployed the Sentinel-2C Earth observation satellite, marking the end of a 12-year journey filled with achievements and milestones.

Vega’s Legacy

Vega, a small yet powerful rocket, was designed to cater to a specific niche in the space launch market: smaller science and Earth observation satellites. Over its lifetime, Vega demonstrated exceptional reliability and performance, completing 20 successful missions.

Vega’s story began on February 13, 2012, when the rocket made its inaugural flight from Europe’s Spaceport in French Guiana. This mission was a qualification flight, successfully deploying nine science cubesats into Earth orbit. The maiden flight set the stage for Vega’s future as a dependable launch vehicle.

Key Missions

Throughout its operational life, Vega played a crucial role in several high-profile missions:

LISA Pathfinder (2015)

One of Vega’s standout missions was launching LISA Pathfinder in 2015. This mission aimed to demonstrate technology for detecting gravitational waves in space, paving the way for future space-based observatories.

Proba-V (2013)

In 2013, Vega launched Proba-V, an Earth observation satellite tasked with monitoring vegetation growth across the globe. This mission was significant for its role in environmental monitoring and climate studies.

Aeolus (2018)

The Aeolus mission, launched in 2018, was another notable achievement. It aimed to measure the global wind profiles, providing valuable data for weather forecasting and climate research.

Technical Specifications

Vega stood 30 meters tall and weighed 137 tons on the launch pad. It consisted of three solid-propellant stages and a liquid-propellant fourth stage. The rocket’s design allowed it to reach space in just six minutes, making it a swift and efficient launcher for smaller payloads.

Notable Achievements

2020: The Largest Payload

In 2020, Vega achieved its highest payload capacity by using a variant of the Vespa adapter called the Small Spacecraft Mission Service. This flight successfully delivered over 50 satellites to orbit, showcasing Vega’s versatility and capability.

IXV Reentry Demonstrator (2015)

Vega’s 2015 mission included the launch of the IXV (Intermediate eXperimental Vehicle), a reentry demonstrator. This mission was critical for testing technology related to reentry and safe return of spacecraft.

“Vega’s role in launching the IXV demonstrated its ability to support cutting-edge space technology and pave the way for future space missions.” — ESA

Transition to Vega-C

As Vega retires, the European Space Agency is transitioning to the Vega-C rocket. Vega-C represents a significant upgrade, offering improved performance and increased payload capacity. The inaugural flight of Vega-C took place in July 2022, successfully launching the LARES-2 satellite and six research CubeSats.

Improvements in Vega-C

Vega-C features several enhancements over its predecessor:

• Two New Solid Propulsion Stages: Improved thrust and performance.
• Uprated Fourth Stage: Enhanced capability for deploying payloads into their desired orbits.
• Newly Designed Fairing: Increased payload capacity and protection.
• Upgraded Ground Infrastructure: Enhanced support for launches and operations.

With Vega’s retirement, ESA is ready to tackle new challenges and opportunities with the Vega-C rocket. Vega-C will take over missions that were previously assigned to Vega. It will also offer better abilities for future space exploration and satellite deployment.

The final Vega rocket launch on September 5, 2024, marks the end of an important era in European space travel. Vega’s legacy is one of reliability and innovation, having supported numerous scientific and Earth observation missions. As ESA transitions to the Vega-C rocket, the future looks promising with improved capabilities and performance. The final Vega launch is a reminder of the progress made in space technology and the continuous effort to advance space exploration.
