Dubai Telegraph - Amazon satellite launch scrubbed due to weather

"Stubborn cumulus clouds and persistent winds make liftoff not possible within the available window," read a liveblog update from operator United Launch Alliance (ULA), a joint venture between Boeing and Lockheed Martin.

Cumulus clouds are a particular danger for rockets as a nearby launch can trigger lightning strikes, ULA added.

Livestream footage showed steam venting from the white Atlas V rocket laden with 27 Project Kuiper satellites as it stood on the launchpad through successive delays.

Liftoff from Cape Canaveral in the US state of Florida had originally been slated for 7:00 pm (2300 GMT).

Like Starlink, the Kuiper service is designed to provide internet access to even the most remote and underserved areas around the world, including war zones or disaster-struck areas.

Once in orbit, the satellites will be positioned hundreds of miles above the Earth, where they will form the foundations of Project Kuiper -- a constellation that Amazon says will include more than 3,200 satellites.

Amazon, owned by billionaire Jeff Bezos, has said the internet service will go live this year.

The project's pricing has not yet been revealed, but Amazon has promised it will be in line with its existing reputation as a low-cost retailer.

Its first launch will put Amazon into direct competition with SpaceX's Starlink and other satellite internet providers.

The Musk-owned SpaceX launched the first batch of its more than 6,750 operational Starlink satellites in 2019 and is by far the sector's biggest player, boasting over five million customers worldwide.

Starlink has provided internet access to several disaster and war zones, including Morocco after a devastating 2023 earthquake there, as well as on the frontlines in Ukraine in its war with Russia.

- High competition -

Unlike traditional internet services that rely on fewer satellites that are situated more than 35,000 kilometers (22,000 miles) from Earth, those offered by Musk and soon Bezos use a low Earth orbit of between 550 and 1,300 kilometers (350-810 miles).

This allows them to relay data more rapidly to Earth, enabling internet access in areas without landline connections by copper or fiber optic cable.

"Cost, complexity, and geography can make it difficult to install traditional, ground-based fiber and wireless connectivity solutions in these areas," Amazon says.

A lower orbit, however, means so-called LEO satellites are only reachable from a smaller area, meaning more are needed for full global coverage and launches are more regular.

Still, it provides a large potential market for Amazon -- one in which it is hoping to become a key player by catching up with its main competitor.

Amazon is planning to boost satellite launches in the coming months and years, with more than 80 flights ordered by firms including ULA, Bezos's space company Blue Origin and even Musk's SpaceX.

These satellites will be gradually dispatched to the low Earth orbit, which is increasingly populated by Starlink as well as other emerging actors including Europe's OneWeb and China's Guowang.

Some have voiced fears the growing number of satellites could lead to congestion and possible collisions, as well as disturbances for astronomical observations.

The role of private hands in space has also raised political questions, particularly given the role of Musk as a key advisor to US President Donald Trump.

Musk has cast doubt on the future of Starlink in Ukraine, where it is essential for military operations in Kyiv's war with Russia that Trump wants to see ended.

He said in March, however, that "no matter how much I disagree with the Ukraine policy, Starlink will never turn off its terminals."
