Watch SpaceX launch 57 more Starlink satellites with its fourth launch in under a month

SpaceX is launching yet another Starlink mission – its fourth in a month – on Thursday afternoon at 4:18 PM EDT (1:18 PM PDT). The launch will carry 57 of SpaceX’s Starlink satellites, which will join the existing constellation in space in order to prepare for SpaceX’s launch of Starlink broadband internet service.

Also on board the Falcon 9 rocket launching today are two BlackSky satellites, which will be used for BlackSky’s earth-imaging and data analytics services. This is another rideshare mission for SpaceX, organized under the program it introduced last year, which allows smallest operators to book rides on missions as part of shared payloads, allowing access to launch services for a starting price of around 1 million. SpaceX flew the first of these missions earlier this month, with a payload that included 58 of its Starlink satellites, alongside three satellites for client Planet.

The mission today will take off from Launch Complex 39A at Kennedy Space Center in Florida, and the Falcon 9 booster used fo rate mission has flown four times previously, including for Crew Dragon’s first unscrewed demonstration mission, as well as twice before for earlier Starlink missions. Reuse of the boosters, combined with rideshare arrangements, are probably helping significantly offset launch costs as SpaceX continues to grow its own Starlink constellation at a rapid clip.

For this launch, all the Starlink satellites are equipped with the deployable sun visor systems that SpaceX came up with to limit the reflectivity of Starlink overall, since it operates relatively close to Earth and has posed an interference hazard with Earth-based night sky observation.

The launch will also include a landing of the first stage booster. This is the fourth launch that SpaceX has done in just three weeks – including the historic crewed Dragon demonstration mission that took place on May 30. It’s also the 10th Starlink launch to date. Next week, SpaceX has yet another launch scheduled for June 30 – a GPS satellite mission that is set to take off from Cape Canaveral Air Force Station.

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 and monito
