SpaceX almost pulled off its ambitious fairing recovery

SpaceX launched one of its Falcon 9 rockets yesterday, placing the first of its Starlink broadband satellites into orbit. While the company did not plan to recover the Falcon 9 booster, it did attempt to recover the payload fairing for the first time. The payload fairing is a nose cone which protects the rocket’s payload from aerodynamic forces and heat, which detaches once the craft has left the atmosphere.

SpaceX planned to recover the fairing by catching it in a giant net attached to a ship.

The fairing was outfitted with directional thrusters and parafoils, which piloted it back.

Elon Musk stated[1] that the fairing landed a few hundred metres away from the ship, and the addition of larger parafoils to slow its descent should allow the ship to catch the fairing in future.

SpaceX delays broadband satellite launch

SpaceX has delayed the launch[1] of its next Falcon 9 rocket to 21 February 2018. The rocket was originally scheduled to launch on 18 February, but it has been delayed to allow for final checks of the craft’s payload fairing. The launch will send SpaceX’s first Starlink broadband satellites into orbit, along with a radar-imaging satellite for Spain’s Ministry of Defense.

SpaceX is using a refurbished first-stage booster to deliver the payload to orbit, after which it will discard the booster into the ocean.

Team at Vandenberg is taking additional time to perform final checkouts of upgraded fairing. Payload and vehicle remain healthy. Due to mission requirements, now targeting February 21 launch of PAZ.

Elon Musk’s satellite Internet plan backed by FCC chairman

Elon Musk’s SpaceX moved closer to another orbital frontier as regulators advanced its application to launch a low-orbit constellation of satellites and join a jostling field of operators trying to cash in on broadband service from space. Federal Communications Commission Chairman Ajit Pai on Wednesday recommended the agency approve Space Exploration Technologies Corp.’s application to provide broadband services using satellite technologies in the U.S. and on a global basis. The proposal now goes to Pai’s four fellow commissioners for consideration at the agency which earlier approved three international operators for satellite-broadband operations: OneWeb, Space Norway AS and Telesat Canada.

“To bridge America’s digital divide, we’ll have to use innovative technologies,” Pai said in an emailed statement. “Satellite technology can help reach Americans who live in rural or hard-to-serve places where fiber optic cables and cell towers do not reach.” The FCC’s move comes as U.S. politicians call for improved internet service in rural areas. President Donald Trump’s infrastructure proposal lists broadband, or high-speed internet service, as eligible for funding alongside traditional projects such as roads and bridges.

Some Democratic lawmakers have criticized the lack of dedicated broadband funding. John Taylor, a SpaceX spokesman, didn’t immediately comment or give further details on the company’s plans, but the FCC last year said SpaceX had requested authority to deploy and operate a constellation of 4,425 satellites operating roughly 700 to 800 miles above the Earth (or 1,110-to-1325 kilometers). Musk founded SpaceX in 2002 to revolutionize space technology, with the ultimate goal of enabling people to live on other planets.

The Hawthorne, California-based company currently flies the Falcon 9 rocket and last week launched the Falcon Heavy, the world’s most powerful rocket in 45 years. SpaceX flew two of its spent boosters back to the Florida coast for a simultaneous recovery on land. SpaceX’s customers include commercial satellite operators, the U.S. space agency NASA and the U.S. military.

Entering the satellite broadband market would add to Musk’s already wide array of business pursuits. The billionaire sells electric cars, solar products and batteries through Tesla Inc. and has been hawking hats and flamethrowers to fund Boring Co., which plans to build underground tunnels for cities including Los Angeles. He also co-founded Neuralink, which is developing technology to connect human brains with computers, and OpenAI, a nonprofit advocating for the responsible development of artificial intelligence.

The broadband project is to get an early test component on Saturday, when SpaceX is slated to launch a pair of demonstration satellites, known as Microsat-2a and -2b, to test a broadband antenna to be included in the proposed constellation, according to a SpaceX document filed with the FCC. The rocket to be launched from Vandenberg Air Force Base in California also will carry Spain’s PAZ satellite. Pai, the Republican FCC chief, said SpaceX’s program could help “unleash the power of satellite constellations to provide high-speed internet to rural Americans.”

The approval would be the first given to an American-based company to provide broadband services using a new generation of low-Earth orbit satellite technologies, Pai said. Satellites will play a critical role in Musk’s efforts to reach his ultimate role of establishing a human settlement on Mars. Building a commercial satellite business will provide SpaceX with revenue and communications know-how that will eventually serve his Martian aspirations.

“We’re going to try to do for satellites what we’ve done for rockets,” said Musk during an interview with Bloomberg Television in January 2015. In order for large broadband constellations to deliver services in the U.S., the FCC must approve their operations to ensure the satellites don’t interfere with other uses, and will operate in a way that lowers the risk of collisions. The FCC last year gave OneWeb access to the U.S. market using a proposed fleet of 720 satellites, and granted Telesat access to the market via 117 satellites already authorized by Canada.

Space Norway won approval for two satellites.

Telesat last year said its service would suffer interference from SpaceX’s operations as proposed, and asked the FCC to deny permission.
