Musk set to invest up to $30 billion in Starlink
Tuesday, 29 June 2021 18:00
Billionaire entrepreneur Elon Musk said Tuesday he plans to invest up to 30 billion dollars to develop his ambitious Starlink satellite internet service.
Starlink plans to deploy thousands of low-orbit satellites to provide high-speed internet to isolated and poorly connected areas.
It has so far deployed over 1,500 satellites and by August it will be able to provide coverage everywhere in the world except the North and South Poles, Musk told the Mobile World Congress, a telecoms industry conference underway in Barcelona, by video.
The Tesla chief said he expects to invest "at least five billion dollars, and maybe as much as ten billion" in Starlink before the service has a positive cash flow.
"Then over time it is going to be a multiple of that, and that would be 20 or 30 billion dollars. It is a lot basically," he added.
Starlink is currently operating in about a dozen countries, with more being added, and it currently has just over 69,000 active users, Musk said.
"We are on our way I think to having a few hundred thousand users, possibly over 500,000 users, within 12 months," he added.

Retro meets retrofit
Tuesday, 29 June 2021 13:50
Retro meets retrofit: The Novespace Air Zero G aircraft is seen here next to Douglas the 1962 VW Transporter. The two are in Paderborn, Germany for the 76th ESA Parabolic Flight Campaign.
The refitted A310 Air Zero G aircraft flies in parabolas that offer teams from various research institutes and universities altered states of gravity to perform experiments and technology demonstrations. Experiments span many disciplines including complex fluidics and human physiology, and this campaign is no exception.
Running from 25 June to 1 July, the 76th campaign features an experiment studying the effect of gravity on hydrodynamics to better protect
Exploring deep space: How can we get there safely and sustainably?
Tuesday, 29 June 2021 13:00
Once the sole dominion of sci-fi movies and novels, the subject of deep space exploration and interplanetary colonization has moved several steps closer to becoming a reality thanks to major advances in aerospace engineering, medicine, and physics.
Sending astronauts to the International Space Station for extended missions has provided a wealth of information about keeping humans alive in the challenging environment of space. Back on earth, scientists and engineers attempt to replicate off-world conditions to test limits for more ambitious missions.
