Finally, a sign of life for Europe’s sovereign satellite Internet constellation

✇Science – Ars Technica

The European Commission announced Thursday it plans to sign a contract with the continent's leading space companies before the end of the year to begin development of a 290-satellite broadband Internet network estimated to cost more than 10 billion euros (about $10.9 billion).

The press release announcing the contract award to IRIS²—known as Infrastructure for Resilience, Interconnectivity and Security by Satellite—did not specify the financial details of the agreement, but European media has widely reported the 10 billion euro cost. The commission's decision follows an evaluation of the best-and-final offer from the SpaceRISE consortium formed by European satellite network operators SES, Eutelsat, and Hispasat.

We’ll do it ourselves

The European Commission, the European Union's executive arm, is managing the IRIS² program, which will also receive funding from the European Space Agency and European industry in a public-private partnership. European governments previously expected to provide around 60 percent of the funding for the initiative. Under that plan, European industry would supply roughly 40 percent of the money in a public-private partnership. The specifics of the final cost-sharing arrangement were not available Thursday.

China’s Long March 6A rocket is making a mess in low-Earth orbit

The upper stage from a Chinese rocket that launched a batch of Internet satellites Tuesday has broken apart in space, creating a debris field of at least 700 objects in one of the most heavily-trafficked zones in low-Earth orbit.

US Space Command, which tracks objects in orbit with a network of radars and optical sensors, confirmed the rocket breakup Thursday. Space Command initially said the event created more than 300 pieces of trackable debris. The military's ground-based radars are capable of tracking objects larger than 10 centimeters (4 inches).

Later Thursday, LeoLabs, a commercial space situational awareness company, said its radars detected at least 700 objects attributed to the Chinese rocket. The number of debris fragments could rise to more than 900, LeoLabs said.

China begins launching a megaconstellation, and it sounds a lot like Starlink

Chinese officials have long signaled their interest in deploying a satellite network, or maybe several, to beam broadband Internet signals across China and other nations within its sphere of influence.

Two serious efforts are underway in China to develop a rival to SpaceX's Starlink network, which the Chinese government has banned in its territory. The first batch of 18 satellites for one of those Chinese networks launched into low-Earth orbit Tuesday.

A Long March 6A rocket delivered the 18 spacecraft into a polar orbit following liftoff at 2:42 am EDT (06:42 UTC) from the Taiyuan launch base in northern China's Shanxi province. The Long March 6A is one of China's newest rockets—and the country's first to employ strap-on solid rocket boosters—with the ability to deploy a payload of up to 4.5 metric tons (9,900 pounds) into a 700-kilometer (435-mile) Sun-synchronous orbit.
