SpaceX’s Ambitious Internet Satellite Project Is Set To Launch This Weekend

With the inaugural launch of the super-powerful Falcon Heavy rocket now in the books, SpaceX CEO Elon Musk is ready to set his sights on an ambitious project known as Starlink. On Sunday, SpaceX will launch two experimental mini-satellites – the first batch of what Musk hopes will eventually comprise a 4000-satellite constellation providing low-cost internet around the globe.

Announced back in 2015, Starlink is designed to be a massive, space-based telecommunications network consisting of thousands of interlinked satellites and several geographically dispersed ground stations. CEO Elon Musk says SpaceX is “going to try and do for satellites what we’ve done for rockets“. The plan is to have a global internet service in place by the mid-2020s, and get a leg-up on potential competitors. Should all go according to plan, the revenue gleaned from the Starlink project could be used to fund eventual missions to Mars.

Two prototypes, named Microsat 2a and 2b, are now packed and ready for launch atop a Falcon-9 v1.2 rocket. A memo from California’s Vandenberg Air Force Base confirmed the launch, which is scheduled for Saturday, February 17 at 6:17AM PDT (Sunday, February 18 at 1:17AM AEDT). In addition to these mini-sats, the Falcon 9 will deliver a 1400kg radar observation satellite called Paz for the Spanish government.

Not much is known about Starlink and the test satellites as SpaceX has been tight-lipped about the whole thing, and for good reason. The company faces tough competition from rivals OneWeb, Samsung, Boeing and Telesat. Both OneWeb (which boasts such partners as Jeff Bezos’ Blue Origin and Richard Branson’s Virgin Orbit) and Samsung have plans to create similar communications constellations using satellites in low-Earth orbit.

But thanks to a publically available government application, some details about the test satellites are known. The twin microsats measure 1.1m x 0.7m x 0.7m, weigh 400kg each, and are powered by a pair of 8m-long solar panels. Once at an altitude of 1125km, SpaceX will test the satellite’s various systems, including its phased array broadband antenna. The company says it will conduct tests of the Ku-band (12-14 GHz) radio communication system about once every 0.9 days for durations lasting less than 15 minutes. Ground stations have been situated in Washington state, California and Texas. SpaceX will also be testing satellite communications on mobile vans equipped with receiving terminals.

News of Sunday’s SpaceX launch comes a few weeks after a US Federal Communications Commission report revealing the number of Americans without access to both fixed and mobile broadband at around 34.5 million (as of 2014). Via the National Broadband Plan, the US government is currently trying to bring high-speed internet to places where service is lacking, especially rural areas.

And as if on queue, the FCC just endorsed a SpaceX application to provide broadband services to the US and worldwide using low-orbit satellites.

“To bridge America’s digital divide, we’ll have to use innovative technologies. SpaceX’s application – along with those of other satellite companies seeking licenses or access to the US market for non-geostationary satellite orbit systems – involves one such innovation,” said FCC chairman Ajit Pai in a statement. “Satellite technology can help reach Americans who live in rural or hard-to-serve places where fibre optic cables and cell towers do not reach. And it can offer more competition where terrestrial internet access is already available.”

Similar applications by OneWeb, Space Norway and Telesat for the US market have already been approved by the FCC, reports Reuters. That being the case, and seeing as the FCC has approved Sunday’s launch, it should only be a matter of time before the rocket company – and now satellite company – gets the green light as well.

As per usual, you can watch Sunday’s launch at SpaceX’s webcast page.

Note: Some people are taking issue with the term “microsatellite” to describe SpaceX’s Microsat 2a and 2b. The label of microsatellite is indeed incorrect, as by definition microsats are between 10 to 100kg (it goes by weight). Microsat 2a and 2b each weigh 400kg, classifying them as “mini satellites”. As to why SpaceX is referring to them as microsats…


Silly Elon, what does he know…
