Nearly three a long time after its debut launch, Europe’s workhorse Ariane 5 rocket has taken to the skies one last time, carrying a pair of communications satellites certain for geostationary orbit.
The sunset liftoff occurred at 6 p.m. EDT (10:00 UTC) July 5, 2023, from launch pad 3 at Guiana Space Center within the South American country of French Guiana. The rocket’s twin solid rocket boosters ignited several seconds after its predominant engine to send the 174-foot (53-meter) two-stage rocket toward space and ultimately delivered the German space agency’s experimental Heinrich Hertz satellite and the Syracuse 4b French communications satellite right into a geostationary transfer orbit some 34 minutes after launch.

“This 117th and last Ariane 5 mission is emblematic in several respects. Ariane 5 has just deployed two telecommunications satellites, Syracuse 4B and Heinrich-Hertz-Satellit, for France and Germany, the primary two contributors to the Ariane program,” Stéphane Israël, CEO of Arianespace, said in an organization statement. “This mission can also be emblematic of Ariane 5’s ability to perform dual launches, which constitutes the very core of its success, with 197 satellites placed in geostationary orbit out of a complete of 239 satellites deployed. Over its profession, Ariane 5 has served 65 institutional and industrial customers from 30 countries.”
Dubbed mission VA261, this was the 117th flight of an Ariane 5 rocket, the primary occurring in 1996. Throughout those 27 years, the Arianespace-built rocket had three partial failures and two total failures, including its very first launch.
The primary launch occurred on June 4, 1996, to deliver the Cluster spacecraft into space for the European Space Agency. Unfortunately, a pc malfunction caused the rocket to abruptly veer off beam and explode seconds after leaving the pad.
It might be nearly a yr and a half later for the second Ariane 5 to take flight, which resulted in a partial failure. Its third launch in October 1998 was the primary to be completely successful. The tenth flight of the rocket was also deemed a partial failure as its upper stage underperformed.
The one other complete failure was in December 2002 when the Ariane 5’s first stage engine failed, causing the rocket to be destroyed by the range safety officer.
Between the 2002 failure and the rocket’s final launch in 2023, Ariane 5 flew 103 times with only a partial failure in 2018 causing satellites to be placed in incorrect orbits.
Among the many greater than 200 satellites and spacecraft orbited by the Ariane 5 include five Automated Transfer Vehicles to deliver cargo to the International Space Station, the European BepiColombo mission to Mercury in 2018 and the $10-billion James Webb Space Telescope on Christmas Day in 2021.
Over the a long time, several variants of the Ariane 5 rocket have flown. The unique “G” version flew 17 times. The “G+” version flew thrice in 2004. Between 2005 and 2009 a “GS” variant flew with no failures.
The ECA, which is the variant used for VA261, got here into service in 2002 and was the most-flown version, having been utilized 84 times. This version was capable of send as much as 23,953 kilos (10,865 kilograms) right into a geostationary transfer orbit.

Finally, an “ES” version flew eight times between 2008 and 2018. It launched all five Automated Transfer Vehicles to the ISS in low Earth orbit in addition to three launches with 4 Galileo navigation satellites each directly right into a medium Earth orbit. The Ariane 5ES had the flexibility to send as much as 44,000 kilos (20,000 kilograms) right into a low Earth orbit.
“Ariane 5 is now taking its place within the annals of world space history,” said Martin Sion, the CEO of ArianeGroup, the parent company of Arianespace. “This final successful mission demonstrates once more its supreme reliability within the service of European autonomy and rounds off an exceptional profession distinguished by a succession of technological and industrial achievements. I share the emotion of all the workers at ArianeGroup, Arianespace, the French and European space agencies CNES and ESA, and all our European partners, who’ve contributed to its success over the course of those 27 years. Together we are actually taking on the challenge of Ariane 6, the beneficiary of the experience acquired with Ariane 5. It would give you the option to evolve and play a full role in guaranteeing independent, sustainable access to space for Europe, in a context of major strategic, economic and environmental challenges, to fulfill the needs of its institutional and industrial customers.”
With the ultimate launch, Europe loses the flexibility to independently send heavy payloads into space until Ariane 6 comes online, which will not be expected until at the least the fourth quarter of this yr.
Ariane 6 has been in development because the early 2010s. At 207 feet (63 meters) tall, the two-stage rocket will are available in two versions “62” with two solid rocket boosters and “64” with 4 solid rocket boosters. The “64” variant is anticipated to give you the option to take as much as 47,730 kilos (21,650 kilograms) into low Earth orbit and 25,400 kilos (11,500 kilograms) into geostationary transfer orbit.
It was purported to be flying as early as 2020 with several years of overlap between it and Ariane 5. Nevertheless, development delays have caused its maiden flight to be delayed several times.
The primary Ariane 6 can be within the “62” variant and send multiple rideshare payloads right into a low Earth orbit after launching from launch pad 4.
