SpaceX CEO Elon Musk announced Saturday that sixty new satellites in the Starlink network will be launched into space on 15 May — the first in a series of thousands that SpaceX hopes to launch over the next few years for internet coverage from space.
The satellites look snugly packed inside the Falcon 9 rocket's nose cone in a picture Musk tweeted. They'll be housed in this payload fairing till the spacecraft releases them into orbit.
"This next batch of satellites will really be a demonstration set for us to see the deployment scheme and start putting our network together," Gwynne Shotwell, SpaceX President and Chief Operating Officer, said at the Satellite 2019 conference in Washington DC, according to SpaceNews. "We start launching satellites for actual service later this year."

SpaceX's Starlink constellation is a massive planned network of 12,000 internet-providing satellites. So far, SpaceX successfully sought approval for all of them from the American Federal Communications Commission.
The demo satellites to be launched on 15 May will be "test satellites" that don't have some of the features (inter-satellite links, for one) intended for the final Starlink satellites. They will sport some highly capable antennas and electric propulsion, though, Shotwell said. A few more Starlink satellites launches are on the cards this year, but specific counts and dates for these depend on how this second set of satellites fare.
Once up and running, satellite internet can provide access to a much wider range of people than today's fibre and cable-based networks can. One of the only disadvantages for widespread use is latency: satellite systems have a latency of 638 milliseconds, which is roughly 20 times slower than wired. Data can be downloaded on these high-latency networks at similar speeds to regular connections, but response times for gaming and other reaction-sensitive uses could be disappointing, according to an Ars Technica report.
There are many satellite internet projects competing with SpaceX's Starlink. Satellite internet firm OneWeb and satellite operator Kepler Communications have work underway on their own constellations and have also filed against Starlink, claiming that it could cause signal interference at the lower elevation and potentially even pose a collision risk. When the FCC approved the project, it found that "the modification proposed by SpaceX does not present significant interference problems and is in the public interest." That's promising.
Beaming down internet from satellites sounds like a terrific idea with a lot of perks, but numerous other companies have run into problems with similar projects. Facebook's Project Athena, after failing to get its drones to work properly, turned to satellites with the aim of launching an internet constellation by early 2019 which the company hasn't yet.
Similarly, Google is working on Project Loon, which aims to provide 4G internet (LTE) to remote regions of the world using hot air balloons. It, too, has run into numerous obstacles, a major patent lawsuit among them. Amazon, too, has also announced Project Kuiper, its own project for satellite internet services.
