Spaceflight Now reports that Europe’s last Ariane 5 rocket “is now scheduled to lift off July 4 after being grounded for more than two weeks due to a problem with the pyrotechnic systems required to jettison the launcher’s strap-on solid rocket boosters.” Europe’s workhorse rocket “is being retired after 27 years of service.” The Ariane 5 was originally “scheduled to fly on June 16, but officials from Arianespace, the rocket’s commercial operator, announced on the eve of launch that they were delaying the mission to replace pyrotechnic transmission lines on the vehicle.” The suspect systems “identified fire explosive charges that jettison one of the two solid rocket boosters two minutes into flight, then to activate the ‘distancing’ system, which uses small thrusters on the boosters to ensure the spent casings safely fly clear of the Ariane 5’s core stage as it continues its climb to orbit.”

Ariane 5 Retirement Leaves Europe With a Launch Crisis
Spaceflight Now reports that Europe is “facing months without its own independent access to space for large satellites following the retirement of its heavy-lift Ariane 5 rocket this week after notching up its 117th and final mission over 27 years of operations.” Ariane 6 is still “undergoing final development and testing.” It is behind schedule “and is unlikely to fly until the very end of this year, with some industry experts suggesting it may not make its maiden flight until later in 2024.” The situation for Europe “is compounded by its smaller vehicle, the Vega-C, remaining out of action following an in-flight failure last December and Russian Soyuz rockets no longer being available for European launches.” An older version of the Vega “is scheduled to fly in September.” European Space Agency (ESA) Director General Josef Aschbacher stated recently “that the continent finds itself in the midst of ‘an acute launcher crisis’ because of the ‘unavailability of home-grown rockets.’”
