(Washington) Amazon launched its first two satellite prototypes on Friday during an important test mission for the development of its future constellation, called the “Kuiper project”, which should provide internet from space and compete with SpaceX.
Liftoff of the Atlas V rocket carrying the satellites took place from Cape Canaveral in Florida at 2:06 p.m. local time, announced the industry group United Launch Alliance (ULA), which provided the transport.
“This is the first time Amazon has put satellites in space,” Rajeev Badyal, vice president of technology for Project Kuiper, said before the launch. “We’re going to learn a lot no matter how the mission goes. »
Amazon, an online sales giant founded by American billionaire Jeff Bezos, plans to place 3,200 satellites in orbit over the next six years.
The two prototypes launched on Friday will be removed from orbit and will disintegrate in the Earth’s atmosphere at the end of the mission.
ULA’s rocket is to deploy them to an altitude of 500 kilometers.
Tests will then be carried out to contact them from Earth, deploy their solar panels, and confirm that all the instruments are working correctly, at the desired temperatures.
The first operational satellites of Project Kuiper are due to launch in early 2024, according to Amazon, which hopes for first tests with customers late next year.
The partnership between Amazon and ULA currently plans 9 takeoffs of the Atlas V rocket and 38 takeoffs of Vulcan Centaur (vehicle in development) to deploy satellites.
The space internet sector is booming, largely dominated for the moment by SpaceX’s Starlink constellation, which has taken a head start. Elon Musk’s company has already put several thousand satellites into orbit, and claims more than two million customers in more than 60 countries.
At the end of September, the merger between satellite operators Eutelsat and OneWeb was completed, and should give birth to a European giant.
China also wants to have its own constellation, GuoWang.
Historical satellite internet services pass through vehicles in geostationary orbit, at an altitude of more than 35,000 km. But their distance means that they cannot achieve the performance of a very high-speed connection, particularly due to the delay between the command and the execution of the request.
Satellites in low Earth orbit, at an altitude of a few hundred kilometers, allow faster communications.
For Amazon, this is a first test, “so we expect to see some failures,” said Gregory Falco, assistant professor of aerospace engineering at Cornell University. Once operational satellite launches begin, “their numbers will pale in comparison to Starlink initially,” he says, “but the constellation will quickly grow.”
