Editor’s note: Minutes before this story changed into posted, Facebook posted a weblog conceding that it become terminating its Aquila software, final its drone factory, and that specializes in partnerships as a substitute.
Facebook’s plans to beam excessive-speed Internet from widespread solar-powered drones inside the stratosphere appears to be in disarray. Two key engineers at the back of its Aquila drones have left the enterprise, and it currently canceled plans for a secret excessive-altitude flight campaign at Spaceport America, probably because Facebook does not have any plane available to installation.
A trove of emails among Facebook and Spaceport America, acquired beneath New Mexico public records regulation and first mentioned by means of Business Insider, details the painstaking process of turning a site for rockets and spaceplanes into a testbed for some of the most important drones in the international.
That years-lengthy mission came to an abrupt halt in advance this 12 months, whilst Facebook determined now not to transport ahead with an excessive-altitude flight campaign. At around the identical time, Andy Cox, the British engineer Facebook hired in 2014 to increase its drones, and Martin Gomez, Facebook’s director of aeronautical systems, left the company.
Federal Aviation Administration (FAA) records additionally show that Facebook has permitted the registration of one of its massive Aquila (eagle in Latin) drones lapse. The other became badly broken on its maiden flight and does not seem to have flown due to the fact that.
The query now could be whether Facebook has abandoned its formidable plans for sun-powered Internet drones altogether—perhaps in favor of a satellite tv for a pc-primarily based device—or is absolutely remodeling and building a new era of aircraft. The corporation might now not immediately provide an answer to that query.
Facebook has been running on Aquilas for years, with a primary full-scale check flight in 2016 and a 2d reaching almost a kilometer in altitude on 22 May final 12 months, from a U.S. Army facility in Arizona.
The demanding situations of building a plane designed to remain aloft for months are legion. One especially that dogged Facebook was how to convey a plane the dimensions of a 737 properly back off to earth while it does no longer have wheels or landing gear.
The emails among Facebook and Spaceport America show that its drones could need to cope with stray animals, archaeological stays, included birds, and even the wrong type of dust.
For lots of 2016 and 2017, the social media giant quietly planned a futuristic launching/touchdown quarter simply north of the (as but unused) Virgin Galactic terminal for Richard Branson’s suborbital spaceplanes. A specially constructed hangar planned for the site became envisioned as domestic to Facebook’s equally revolutionary Aquila drones, permitting the first flights at their planned operational altitude of 18 to 27 kilometers, and trying out their capacity to provide Internet connectivity to a 50 km-radius beneath them.

Just 9 days after Aquila’s first flight in 2016, a site choice professional from Facebook’s international connectivity corporation internet.Org requested Spaceport America officials to signal a non-disclosure agreement about constructing a facility there, emails show. In an attempt to keep its anonymity, Facebook would be cited by the codename Denali in lots of public documents.
Problems quick emerged. For a start, although Spaceport America has 3.6 kilometers of the runway and the Aquila wishes handiest 335 meters to take off, it needs to launch into the wind, from a wheeled dolly that remains on the ground. (The lack of landing equipment is so the aircraft can save weight.)
Facebook Aquila touchdown concept.
Proposed launching and landing zones for Facebook’s drones at Spaceport America.
The geometry of the Spaceport runway might have avoided the drones from being launched when the wind became blowing from sure angles, except greater pavement turned into brought to the east or west facets of the runway. “It might be a prime and probably steeply-priced construction complication, however, it is able to be accomplished,” wrote Bill Gutman, Director of Aerospace Operations for the New Mexico Spaceport Authority (NMSA).
Waiting for the wind to align with the runway become first-class for Aquila’s preliminary checks but would rarely work for a sustained marketing campaign of flights. At the Spaceport, Facebook determined to put together its very own launch and touchdown place alternatively, at once at the bare floor.
Landing is the maximum hazardous time for the Aquila. On its maiden voyage in 2016, Facebook’s unique plane encountered turbulence quickly earlier than the touchdown. The moving air currents deflected after which broke its proper wing. In the subsequent crash, the drone sustained “vast harm to [its] primary shape” in addition to charring to at least one battery, in step with a twist of fate record filed with the U.S. National Transportation Safety Board. That aircraft does now not appear to have flown given that.
For 2017 take a look at in Arizona, Facebook’s 2nd Aquila prototype took off from a runway, however, landed effectively on aa hundred and fifty-meter circle of carefully groomed sand about 15 centimeters (6 inches) deep, christened the ‘Aquila Beach.’ Kevlar pads bonded to the plane’s vehicles reduced damage, even though the plane’s propellers can be visible hitting the floor earlier than the plane itself. In New Mexico, the aircraft could be descending from a lot higher altitudes and Facebook engineers wanted a correspondingly large launching/landing circle, up to 600 meters wide.
The organization’s idea turned into to completely clear a place northwest of the primary runway of mesquite timber and rocks, then replant it with native grasses to shape a smooth touchdown mattress. But Gutman foresaw a few problems with that technique. “We trust the circle misses known archaeological websites, however, we’re verifying that with our representative,” he wrote to Facebook in July 2016. “We [also] probably want to time the surface paintings to avoid stressful nesting birds.”
Christine Anderson, executive head of NMSA, was hoping that Facebook turned into no longer in a hurry to start testing. “It might also take quite some time for a seed to grow… Like six months to a yr or more, despite the fact that we water it once in line with the week,” she wrote to Facebook. “Can you land on naked dust when you have to?”
Facebook’s website professional, Kevin Slover, confirmed that the Aquila could land on dirt, although “we’d need to do what we ought to ‘fluff it up’ as much as possible with the aid of clearing, plowing, and harrowing.”
What’s extra, Gutman said, the large landing circle might need a sports fence to keep out cattle and other large animals. The first fence proposed by way of Facebook could have run immediately via the Spaceport’s gas farm. Gutman referred to that that is the planned domestic of a “pretty massive” garage vessel containing the nitrous oxide propellant for Virgin Galactic’s SpaceShip Two vehicle. Accommodating such restrictions may want to upload up to $four hundred,000 or 14 weeks to Facebook’s creation plans, Anderson wrote.
Facebook’s hangar would be a tent-like tensioned membrane structure, furnished by using Sprung, the identical business enterprise that constructed Tesla’s new Model three production line constructing in California.
Lacking a take a look at the website online, two of its founding engineers, and probably even plane to fly, Facebook’s Aquila software looks to be on pause, as a minimum.
Facebook desired to check the drones’ ability to relay Internet indicators in a number of frequency bands, consisting of the Ka-band (27.5 to 29.7 gigahertz), V band (47.2 to 48.2 GHz), and a few slender K and Ka bands proposed through the International Telecommunication Union mainly for excessive-altitude structures just like the Aquila. A destiny fleet of Aquila drones might hook up with every different the usage of unfastened-space laser optical links, focused around 1550 nm.
Facebook isn’t the primary tech company to express a hobby in trying out Internet drones at the Spaceport. In 2016, Google examined a 5G device called Skylanders there, using an optionally-piloted plane and probably its very own high-altitude drones. Google’s discern employer, Alphabet, terminated that ‘moonshot’ software in 2017.
In February, FCL Tech filed a utility with the Federal Communications Commission (FCC) for an LTE-primarily based device with a 50-km radius, probably for use with the Aquilas. Slover had previously written to the NMSA: “Our IT oldsters would love to [coordinate] with you to get the connectivity we’re after. We had been thinking about the use of our personal equipment to provide the spine to our hangar, but our team would really like to discover your answer as properly.”
However, neither FCL Tech nor Facebook sought permission from the FCC to test at the Spaceport using the drone’s E-band or different high-frequency alerts. Neither did Facebook make any extreme progress with building its hangar or preparing the launching and touchdown place. Soon after the FCC software, Facebook instructed Spaceport America that it’d no longer be checking out there in spite of everything.
A Facebook spokesperson advised Spectrum: “Beginning in 2016 we worked with Spaceport to look if their facility might be a capability check site for our connectivity efforts. Because web page investments like those require an extended lead time, we frequently pursue more than one alternatives at once and make initial investments and arrangements so we are able to move fast if we turn out to be wanting to use that site. We, in the end, signed a quick-term rent with Spaceport and worked with them on a few lightweight web page prep, however, we haven’t any plans for in addition investment or any operations at the moment.”
Lacking a take a look at the website, two of its founding engineers, and probably even plane to fly, Facebook’s Aquila software seems to be on pause, as a minimum.
But possibly Facebook is best anticipating the subsequent era of a plane. Way returned in the summertime of 2016, Bill Gutman wrote to Kevin Slover, “I trust you instructed us that the course the Aquila challenge may be taking within the destiny could be for the car to take off and land using a runway rather than a prepared circle.”
“You’re accurate,” Slover responded. “The plan is for an average runway take-off and landing.” If the subsequent flock of Aquilas sports activities tougher underbellies or landing gear, Facebook will not fear about fluffing up dust or worrying their feathered brethren in any case.
