SpaceX to launch space internet satellites
Falcon 9 is getting ready to take its first two Starlink internet satellites into orbit this Wednesday. Read more: http://zd.net/2BvqpA5

Tesla and SpaceX CEO Elon Musk has used Twitter to tease the imminent launch of the first batch of low Earth orbit satellites for providing broadband to humans across the planet.     

Musk is betting that his SpaceX Starlink constellation of around 12,000 satellites will be able to deliver high-speed internet to people at an affordable price.   

Musk on Sunday showed off images of some of the first 60 satellites that SpaceX will launch into space this week, probably on Wednesday, inside a Falcon 9 rocket.

Musk has predicted the network will be able to go live in the mid-2020s once about 800 satellites have been launched. The network will eventually consist of around 12,000 satellites that would deliver 1Gbps speeds to users on Earth.

In April, US regulator the Federal Communications Commission (FCC) approved SpaceX’s plan to launch 4,409 Starlink satellites with 1,584 orbiting at an altitude of 550km rather than the previous request of 1,150km. The FCC also approved over 7,000 additional Starlink satellites in November.   

Musk noted that the 60 satellites to be launched this week are “production design”, unlike its Tintin A and B demo satellites that were launched early last year. 

The plan is that thousands of small satellites will form a mesh network that will use V band, which covers 40GHz to 75GHz, to connect with each other. They’ll use Ka/Ku radio bands to deliver internet to receivers on Earth.

Other firms in the broadband space race include Kepler, Telesat Canada, LeoSat, and Amazon CEO’s Blue Origin.

Musk warned that “much will likely go wrong” on the first mission and that for “moderate” coverage, SpaceX would need 12 successful missions with about 60 satellites each to total 760 satellites. 

This week’s launch won’t become part of the actual Starlink mesh network. While the 60 satellites are production design, as Spacenews reports, SpaceX’s president and chief operating officer Gwynne Shotwell last week said they were still demonstration satellites that are missing the equipment to link up as a mesh network. 

Amazon is currently known to be planning to put 3,236 internet-beaming satellites into low Earth orbit, with 784 at 367 miles (590km), 1,296 at 379 miles (610km), and 1,156 at 391 miles (630km).

Polestar 2 adds a video streaming app to pass the time while charging

Published

on

Polestar is adding a video streaming app to the Android Automotive OS dashboard of the Polestar 2, though as you’d hope the EV has some strict limits on playback depending on whether you’re driving or not. Currently in beta, the Polestar 2 video app is designed to give drivers something to occupy themselves as they wait at public chargers.

Certainly, the growing number of DC fast chargers available in the wild have helped with cutting down that time. So, too, has Polestar’s incremental update to just how fast the EV actually tops-up, with an OTA firmware update back in February 2021 nudging the charging rate to 155 kW from the 150 kW it launched with.

All the same, even if you find such a charger, it’s still going to take you longer to top-up than pumping gas might. European Polestar 2 owners will now be able to entertain themselves with some video as they hang out in the cabin.

There’ll be a choice of news programming and national TV broadcasts, where available, Polestar says, along with a video playlist which is curated by the automaker. To begin with there’ll be SVT in Sweden, TV2 in Norway, and GOPlay and RTBF in Belgium. All European market also receive feeds from BBC Ideas, Al Jazeera English, and Germany’s tagesschau. More options will be added over time.

What you won’t be able to do, though, is play video while you’re actually driving. The Polestar video app can be accessed when the EV is parked; switching out of Park and into Drive or Reverse will automatically flip the stream into audio-only mode. That way you can hear the show, but not see it on-screen which could be a source of driver distraction.

How well it goes down with owners, meanwhile, remains to be seen, and indeed Polestar is seeing this beta version as a way to test out the popularity of new features. “We will receive feedback – both good and bad – that will help to refine the app based on thousands of use cases, rather than a small, defined set,” Thomas Ingenlath, Polestar CEO, explains. “We will also continue to add channels in the future, which gives the app huge growth potential since it is realistically able to integrate any web-based streams.”

Sweetening the deal is the fact that viewers won’t have to pay extra for the data used by streaming, since that will be included in the car’s own data plan.

It’s unclear when – or even if – the app will come to Polestar 2 cars in North America. Current legislation certainly doesn’t prevent it, with Tesla already offering streaming on its EVs, though again with limits on when you can watch depending on whether the car is in motion. We’ve got a request in with Polestar for more information, and will update when we hear back.

Brembo introduces G Sessanta Concept brake caliper for motorcycles

Published

on

Italian braking expert Brembo is celebrating its 60th anniversary this year. Commemorating this glorious event is the brand’s newest brake caliper concept for motorcycles. The latest G Sessanta Concept is unlike any brake caliper you’ve seen before. Embodying the desirable traits of a genuine concept, G Sessanta is Brembo’s vision for the future of mobility.

The Brembo G Sessanta Concept has innovative LED lighting technology that is purpose-built on the body of the caliper. It not only enhances form and function but it serves as a communication interface for the driver. “The light takes Brembo’s experience in the use of color to a higher level, giving it new values,” according to Brembo’s PR.

Wireless technology is at the heart of G Sessanta. The colors and lighting effects can be personalized using your smartphone or gadget. You can choose from changing lighting moods or allow the system to select the lighting effects based on existing surroundings.

What’s more, it can relay warning lights to the driver, like when the brake pads need replacing. And if you find it tricky discerning your bike from hundreds of others in a parking lot, G Sessanta can emit a courtesy light to point you in the right direction.

Brembo has been setting new standards in braking technology since the brand’s inception in 1961. Born in Paladina, Italy, Brembo’s 46-year motorsports history is a testament to the brand’s commitment towards performance and innovation. The Cadillac CT5-V Blackwing has optional Brembo carbon-ceramic brakes with copper-free brake pads and electronic sensors to monitor the brake pad thickness, all while weighing 64 pounds less than cast-iron brakes.

However, will Brembo’s G Sessanta Concept make it to four-wheeled conveyances? We’ll have to wait and see, and it’s interesting to witness how lighting or wireless technology can benefit auto brakes, as well. Still, it’s good to know that significant OEM and aftermarket suppliers are infusing new technology into their products.

The Citroën Ami Cargo is an electric microvan for small business errands

Published

on

You’ve probably heard of the Citroën Ami EV, a micro EV that’s small enough to be driven by 14-year-old teeny boppers without a full driving license – in France, at least. Nevertheless, the Ami is a brilliant and dirt-cheap city car with a conscience. And now, Citroën has unveiled the microvan version of the Ami, which makes it doubly desirable.

The Citroën Ami Cargo offers all the little goodness of a regular Ami, but it has small or micro-enterprises in mind. “Inspired by the version designed for individuals, My Ami Cargo retains the idea that guided the design of Ami,” said Richard Meyer, Stellantis Commercial Vehicles Strategy and New Mobilities manager.

Small on the outside yet big on the inside, Citroën Ami Cargo has a vertical partition and modular shelves to store cargo boxes, plants, small kennels, and whatever you fancy. The modular rack can hold 40 kg of weight and has a flat top to form a mobile desk. “This is why we created an innovative interior space, allowing us to make an offer that’s unique on the market while retaining the simplicity and clever design of the Ami,” added Meyer.

What’s more, Citroën’s electric microvan has a flat floor with two levels of height adjustment, allowing you to carry taller objects up to 1.2-meters. All told, Citroën Ami Cargo can accommodate up to 400 liters or 140 kilos (308 pounds) of stuff. In the rear, it also has a closed storage box to secure valuable things like smartphones, tablets, small laptops, and parking tickets.

Otherwise, the cargo version remains a basic Ami minus the passenger seat. It still measures 2.4-meters by 1.4-meters, perfect for tight parking spots. It has a single electric motor and a 5.5 kWh lithium-ion battery. It only has eight horsepower, but how many horses do you need to motivate a tiny van?

As it turns out, it doesn’t take much. The 6 kW electric motor enables a modest 30 mph (45 km/h) top speed, so don’t expect to be blown away like in a Tesla Model Y. The tiny battery achieves 47 miles of range on a good day. But when the battery runs out of juice, it replenishes in just three hours using a primary 220V domestic socket.

Also, the Citroën Ami Cargo is endlessly customizable to fit any purpose. The best part is the price: You can purchase the Ami Cargo in France for as low as €6,490 ($7,800) with a €900 ($1,081) deductible, or you can rent it as part of a long-term lease agreement starting at under €25 ($30) monthly
