SpaceX records another first for reusable rocketry by catching Falcon Heavy fairing with a boat

SpaceX has managed to do another thing that seemed audacious and highly unlikely after a few early botched attempts. It used a ship at sea to catch the falling nosecone that shielded the cargo aboard its Falcon Heavy rocket during launch.

The maneuver saw a SpaceX-owned barge called Ms. Tree rigged with a giant net slung across four large protruding beams navigate to a point off the Florida coast in the Atlantic Ocean to await the SpaceX fairing’s return once it separated from the rocket. Falcon Heavy launched from Kennedy Space Center last night for its STP-2 mission.

After beginning its career serving the launches that take place from Vandenberg Air Force Base in California, Ms. Tree (née Mr. Steven) traveled to the East Coast via the Panama Canal earlier in the year to make some attempts at catching SpaceX rockets launched from Florida.

The boat was put into service during a SpaceX launch from Vandenberg for the first time in February 2017, but the fairing missed the net and the boat, and the same is true for three subsequent attempts in 2018, during which SpaceX also decked the boat out with larger nets to give it a better chance of success.

This is a big deal for SpaceX because it likely makes re-using the fairings much more feasible. CEO Elon Musk has said that the company is basically throwing away $6 million every time it loses one of these fairings to a hard ocean landing, and so SpaceX has been working on a way to recover the parts – just like it recovers boosters via controlled descent.

The nosecone parts (each launch has two, one fairing for each half of the payload capsule) have been able to control their descent using small thrusters and a parachute which SpaceX can steer to a degree from the ground since the company’s 2017 SES-10 mission, but until now they’ve dropped in the ocean, which makes recovery more challenging and difficult to refurbish.

During this launch, Ms. Tree caught one half of the fairing as planned, and the other half landed in the water nearby. The big test now will be examining the returned caught fairing to determine if it’s suitable for refurbishment and re-flight, which could help a lot in trimming SpaceX launch costs further still.

Uber co-founder Garrett Camp steps back from board director role

Uber co-founder Garrett Camp is relinquishing his role as a board director and switching to board observer — where he says he’ll focus on product strategy for the ride hailing giant. Camp made the announcement in a short Medium post in which he writes of his decade at Uber: “I’ve learned a lot, and realized that I’m most helpful when focused on product strategy & design, and this is where I’d like to focus going forward.” “I will continue to work with Dara [Khosrowshahi, Uber CEO] and the product and technology leadership teams to brainstorm new ideas, iterate on plans and designs, and continue to innovate at scale,” he adds. “We have a strong and diverse team in place, and I’m confident everyone will navigate well during these turbulent times.” The Canadian billionaire entrepreneur signs off by saying he’s looking forward to helping Uber “brainstorm the next big idea”. Camp hasn’t been short of ideas over his career in tech. He’s the co-founder of the web 2.0 recommendatio...

Drone crash near kids leads Swiss Post and Matternet to suspend autonomous deliveries

A serious crash by a delivery drone in Switzerland have grounded the fleet and put a partnership on ice. Within a stone’s throw of a school, the incident raised grim possibilities for the possibilities of catastrophic failure of payload-bearing autonomous aerial vehicles. The drones were operated by Matternet as part of a partnership with the Swiss Post (i.e. the postal service), which was using the craft to dispatch lab samples from one medical center for priority cases. As far as potential applications of drone delivery, it’s a home run — but twice now the craft have crashed, first with a soft landing and the second time a very hard one. The first incident, in January, was the result of a GPS hardware error; the drone entered a planned failback state and deployed its emergency parachute, falling slowly to the ground. Measures were taken to improve the GPS systems. The second failure in May, however, led to the drone attempting to deploy its parachute again, only to sever the line...

How the world’s largest cannabis dispensary avoids social media restrictions

Planet 13 is the world’s largest cannabis dispensary. Located in Las Vegas, blocks off the Strip, the facility is the size of a small Walmart. By design, it’s hard to miss. Planet 13 is upending the dispensary model. It’s big, loud and visitors are encouraged to photograph everything. As part of the cannabis industry, Planet 13 is heavily restricted on the type of content it can publish on Instagram, Facebook and other social media platforms. It’s not allowed to post pictures of buds or vapes on some sites. It can’t talk about pricing or product selection on others.   View this post on Instagram   A post shared by Morgan Celeste SF Blogger (@bayareabeautyblogger) on Jan 25, 2020 at 7:54pm PST Instead, Planet 13 encourages its thousands of visitors to take photos and videos. Starting with the entrance, the facility is full of surprises tailored for the ‘gram. As a business, Planet 13’s social media content is heavily restricted a...
