Jeff Bezos, the founder of the online retail giant Amazon, is about to expand his interests in space.
He’s set to launch two prototype satellites for a broadband mega-constellation he calls Project Kuiper.
Mr Bezos is planning to put up more than 3,200 spacecraft in the next few years to deliver internet connections to anywhere on the globe.
He hopes to challenge Elon Musk’s Starlink, which already offers satellite internet in many countries.
The two small satellites launching on Friday – KuiperSat-1 and KuiperSat-2 – will trial the necessary technology.
They’ll be carried into a 500km-high (310 miles) orbit by an Atlas-5 rocket.
The flight from Cape Canaveral Space Force Station in Florida is scheduled to occur at 14:00 EDT (18:00 GMT; 19:00 BST).
Amazon began research and development on the $10bn (£8bn) Project Kuiper in 2018.
The ambition is to join the rapidly growing market for high-bandwidth, low latency (minimal delay) internet connections that are bounced across the sky, as opposed to through fibre connections on the ground.
Elon Musk’s SpaceX company is the leader in the field and already has more than 4,800 working spacecraft in orbit.
UK-based Eutelsat-OneWeb has also built out a network of 620 satellites, but the list of wannabes in the sector is growing all the time with similar projects announced in Canada, the EU, and China, in addition to proposals from other US companies.
Mr Bezos is in a hurry to deploy his network.
Amazon has a licence from the US Federal Communications Commission (FCC) to use the necessary radio frequencies, but the terms of this licence demand that at least half of the Kuiper system is in orbit by July 2026, and that the full roll-out be completed by July 2029.
This will demand a furious launch campaign, and Amazon has agreements in place with rocket companies for almost 100 flights.
A potential stumbling block, however, is that the bulk of these missions is booked on vehicles that have yet to enter service and it’s not uncommon for new rocket systems to fail on their early outings.
If this were to happen, it could dramatically compromise the speed with which Amazon is able to get Kuiper up and running.
