The meeting of Amazon’s massive new satellite-internet constellation is underway.
A United Launch Alliance (ULA) Atlas V rocket lifted off from Florida’s Cape Canaveral House Pressure Station at present (April 28) at 7:01 p.m. EDT (2301 GMT), carrying 27 of Amazon’s “Mission Kuiper” broadband spacecraft towards low Earth orbit (LEO).
It was the primary of greater than 80 deliberate launches to construct out the Mission Kuiper megaconstellation, which is able to ultimately harbor greater than 3,200 spacecraft.
That is an enormous quantity, however it will not set a file; SpaceX’s Starlink broadband community, which already beams service right down to prospects around the globe, at present consists of more than 7,200 operational spacecraft.
And Starlink — maybe Mission Kuiper’s largest competitor — is rising on a regular basis: SpaceX has launched 31 Starlink missions up to now this 12 months, with many extra on the docket. In reality, there was a Starlink launch lower than three hours earlier than at present’s Atlas V launch, with one other deliberate for lower than 4 hours after.

If all goes in keeping with plan at present, the Atlas V will deploy the 27 Mission Kuiper satellites 280 miles (450 kilometers) above Earth. The spacecraft will then make their very own option to their operational altitude of 392 miles (630 km).
“Whereas the satellites full the orbit-raising course of, we’ll sit up for our final mission goal: offering end-to-end community connectivity,” Amazon representatives wrote in a prelaunch statement.
“This includes sending information from the web, by our floor infrastructure, as much as the satellites, and right down to buyer terminal antennas, after which repeating the journey within the different route,” they added.
Mission Kuiper is anticipated to start offering protection to prospects later this 12 months, in keeping with Amazon.
As we speak’s launch was the second general for the Mission Kuiper program. An Atlas V despatched two prototype satellites to orbit in October 2023, on a take a look at mission designed to show out the corporate’s know-how and inform the design of the constellation’s operational craft.
And there are appreciable variations between these pioneering satellites and those that went up at present.
“We now have improved the efficiency of each system and subsystem on board, together with phased array antennas, processors, photo voltaic arrays, propulsion methods and optical inter-satellite hyperlinks,” Amazon representatives mentioned in the identical assertion.
“As well as, the satellites are coated in a dielectric mirror movie distinctive to Kuiper that scatters mirrored daylight to assist make them much less seen to ground-based astronomers,” they added.
Many of the remaining 80-plus launches will probably be carried out by the Atlas V and its successor, ULA’s new Vulcan Centaur rocket. Amazon has additionally signed launch offers with Jeff Bezos’ Blue Origin, SpaceX and France-based Arianespace.
As we speak’s launch was initially scheduled for April 9, however unhealthy climate scuttled that attempt. ULA and Amazon then needed to look ahead to a launch slot to open up on the Jap Vary, the Florida spaceport and testing web site operated by the U.S. House Pressure.
