Space Europe is moving forward with a successful launch of Ariane 5


The European launcher successfully put two telecommunications satellites into orbit on its 113th take-off on Wednesday night.

The earth trembles, the sky ignites for a brief moment, then comes the crash, deafening: the Ariane 5 rocket, symbol of Europe's access to space, took off on Wednesday from the Guyanese jungle for one of his ultimate missions.

It successfully placed two telecommunications satellites into orbit.

The rocket took off at 6:50 p.m. local time (21:50 GMT) from the Kourou Space Center in French Guiana, after a 45-minute countdown interruption for technical checks.

The launcher carried under its fairing the Measat-3d satellite, from the Malaysian operator Measat, and GSAT-24, operated by the commercial arm of the Indian space agency (ISRO), Arianespace and Arianegroup announced in a joint press release.

The satellite released at nearly 1,200 km altitude

The two satellites, totaling a payload of 9.8 tonnes, are dedicated to telecommunications services and satellite TV broadcasting.

Measat 3-d will also be able to provide high-speed internet connection services and will be used by the South Korean space agency to improve air traffic management in the country.

Just over 28 minutes after the launch, the launcher released Measat-3d at an altitude of almost 1,200 km, then 12 minutes later the GSAT-24 satellite as the launcher flew over the Indian Ocean at 3,800 km altitude.

From these “geostationary transfer” orbits, the two satellites will return to their position nearly 36,000 km from the Earth, from where they will begin their missions.

The expected lifetime of Measat-3d is more than 18 years, and 15 years for GSAT-24.

Only two more flights this year

For the Guiana Space Center (CSG), this launch is the second of the year, the first since the final launch of the Russian Soyuz rocket from Kourou on February 10: the Russian invasion of Ukraine cut short any European cooperation with Russia and deprived Kourou of the three other Soyuz launches initially planned for 2022.

The European Space Agency (ESA), responsible for European launcher programs, must still ensure the launch of two Ariane 5 and two Vega rockets - smaller than Ariane - by the end of the year.

Among them, the inaugural launch of Vega-C, a more powerful version of Vega, is scheduled for July 7.

The first launch of Ariane 6, which will take over from Ariane 5, has been postponed to 2023.

After this 113th launch of Ariane 5, a rocket that began its career in 1996, only 4 flights remain, two this year and two in 2023. One of which is emblematic: the European Space Agency's (ESA) Juice mission to the icy moons of Jupiter.
