    The European Space Agency (ESA) declared success after an Ariane 6 rocket fired its core stage engine in French Guiana for seven minutes on Thursday, clearing one of a handful of remaining hurdles before the new launcher can lift off on its first test flight.

    The Ariane 6's inaugural launch, now scheduled for next year, has been delayed repeatedly since ESA approved the new rocket for development in 2014. The test-firing of the Ariane 6 main engine on a launch pad at the Guiana Space Center in South America last week was the most significant test not yet accomplished on the rocket's preflight checklist.

    The test lasted 426 seconds—a little more than seven minutes—while a full-size test model of the Ariane 6 rocket remained on its launch pad. In order for the rocket to actually take off, it would need to light its four strap-on solid-fueled boosters. That was not part of the plan for Thursday's test.

      The Ariane 6 rocket will now debut no earlier than the spring of 2024

    The European Space Agency posted an update Friday on the status of its flagship rocket, the Ariane 6 vehicle. While the space agency did not provide a concrete launch target for the rocket's debut flight, it shared information on key milestones to be completed, including a test firing of the rocket's first stage in French Guiana.

    Even without an updated launch date, it can reasonably be inferred from the new information that the Ariane 6 rocket will not launch this year. The question now is how far the debut of the much-anticipated rocket will slip into 2024.

    Here's why: During a news conference in October 2022, the director general of the European Space Agency, Josef Aschbacher, laid out the pathway for the Ariane 6 rocket to make its debut in 2023. "There are three very big milestones ahead of us that need to be accomplished by the first quarter of 2023 in order for the inaugural flight by the end of next year," he said at the time.

      Upper stage issue causes Arianespace launch failure, costing 2 satellites

    An overnight launch of Arianespace's Vega rocket failed after reaching space, costing France and Spain an Earth-observing satellite each. The failure represents the second in two years after Vega had built up a spotless record over its first six years of service.

    The Vega is designed for relatively small satellites, typically handling total weights in the area of about 1,000 kilograms, though it can lift heavier items into lower orbits or take lighter ones higher. The trip to space is powered by a stack of three solid rocket stages; once in space, a re-ignitable liquid-fueled rocket can perform multiple burns that take payloads to specific orbits.

    Vega had started off with a flawless launch record, averaging about two a year for its first six years of service before a solid booster failure caused the first loss in 2019. After the investigation into that failure, the rocket had returned to service just over two months ago with a successful launch.
