SpaceX’s new Starlink Aviation service brings 350 Mbps WiFi to private jets

The new service will provide 350 Mbps internet, even while taking off and landing.

SpaceX just announced its new Starlink Aviation service, which will allow high-speed in-flight internet that will allow users to make voice calls and stream videogames, according to the company.

The new service promises speeds of up to 350 Mbps for airliners and is aimed mainly at private jet contractors. Earlier this year, SpaceX also announced a partnership with Hawaiian Airlines to bring free WiFi to its flights starting early next year.

SpaceX recently announced Starlink RV and Starlink Maritime. It’s now taken the logical next step, expanding its Starlink service into the skies.

Energy jet traveling 7 times the speed of light appears to break the laws of physics

Gravitational waves are invisible to the naked eye, but can be detected with instruments such as the Large Interferometer Gravitational Wave Observatory (LIGO) in Pasadena, California. So, after LIGO detected the first blast of waves from the colliding stars in 2017, astronomers around the world trained their telescopes on the merger to learn whatever they could about it. Before long, astronomers saw visible evidence of a high-speed jet of particles, blazing out of the collision site and lighting up globs of matter that had been ejected by the stars.

In their new paper, astronomers analyzed that jet with NASA’s Hubble Space Telescope, the European Space Agency’s Gaia space observatory and several additional radio telescopes on Earth. With these observations, the team calculated both the actual speed of the jet, and the perceived physics-defying speed.

The beyond-light-speed illusion arises from the difference in speed between the particles in the jet, and the light particles (or photons) that they emit. Because the jet’s particles move nearly as fast as the light they emit, it can appear as though particles in the early part of the jet are arriving at Earth at nearly the same time as photons in the later stages of the jet — making it appear as though the jet is actually moving faster than the speed of light.

Webb space telescope reveals “Pillars of Creation” in stunning new detail

But the true nature of the pillars was famously revealed in 1995 by the Hubble Space Telescope, an image that wowed the public and was soon one of the most recognized and widely published photos ever captured by the venerable observatory.

But Hubble is primarily a visible-light telescope with only a limited ability to detect cloud-piercing infrared emissions from the interior of the pillars and from stars shining in and behind a translucent, obscuring layer of gas making up the interstellar medium that is most apparent looking into the plane of the galaxy.

Enter the $10 billion James Webb Space Telescope.

Rooftop wind system delivers 150% the energy of solar per dollar

Aeromine says its unique “motionless” rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.

Distributed energy generation stands to play a growing part in the world’s energy markets. Most of this currently comes in the form of rooftop solar, but in certain areas, wind could definitely play a bigger part. Not every spot is appropriate for a bladed wind turbine, though, and in this regard, University of Houston spinoff Aeromine Technologies has designed a very different, very tidy form of rooftop wind energy capture that looks like it could be a real game-changer.

As with traditional wind turbines, size is key. So while Aeromine’s wind energy boxes take up a relatively small footprint on your roof, they’re still pretty bulky. The wings themselves are maybe 10 feet (3 m) high, at a rough guess, and looking at the latest imagery they’re now sitting on top of boxes that might add another 6 ft (1.8 m) or more to their height – so they’re no shrinking violets. On the other hand, they don’t create the noise, or the constantly moving visual distraction of a regular, bladed turbine, so they may prove to be less unwelcome in populated areas.

The 2022 Global Satellite Servicing Forum, the DARPA-originated u0040_CONFERS consortiumu2019s annual event, is Oct

The 2022 Global Satellite Servicing Forum, the DARPA-originated @_CONFERS consortium’s annual event, is Oct. 19–20. In-space servicing and manufacturing stakeholders will discuss in-space lessons learned and their work toward achieving common technical and safety standards to extend satellite utility, resilience, & reliability.
