Three Percent of SpaceX’s Starlink Satellites Died

Piling Up

SpaceX has launched about 775 Starlink satellites so far but plans to have 42,000 by the time the constellation is complete. At a three percent failure rate — assuming it stays consistent — that amounts to 1,260 immobilized satellites waiting to smash into other stuff in space.

“I would say their failure rate is not egregious,” McDowell told Business Insider. “It’s not worse than anybody else’s failure rates. The concern is that even a normal failure rate in such a huge constellation is going to end up with a lot of bad space junk.”

Soldiers Become Another Node In DoD’s Internet Of Things: ENVG-B

Article on the soldiers of the very near future. This is when Internet of Things is used for military purposes allowing better situational awareness.


ENVG-B is still being fielded across the force, but the Army is already developing a next-gen system, a set of augmented reality targeting goggles — a militarized Microsoft HoloLens — known as IVAS. The Army’s also developing an Adaptive Squad Architecture to ensure all the different technologies going on a soldier’s body are compatible.

“ENVG-B is a system of systems,” Lynn Bollengier of L3Harris Technologies said at this week’s annual Association of the US Army conference. These systems include integrated augmented reality aspects from the Nett Warrior tablet, as well as wireless interconnectivity with weapon sights.

Combined, that means a soldier wearing the ENVG-B can look through their binoculars, turn on the camera in their rifle’s sight, and point that sight around a corner to see and shoot, without exposing anything more than their hands or the rifle.

SpaceX targeting this weekend for Starlink launch from Kennedy Space Center

SpaceX is targeting this weekend for its next Falcon 9 rocket launch from Kennedy Space Center, this time with another batch of Starlink internet satellites.

If schedules hold, teams will give the go-ahead for the 230-foot rocket to launch from pad 39A at 8:27 a.m. Sunday, the opening of an instantaneous window. It must launch at that time or delay to another day.

About eight minutes after liftoff, the rocket’s 162-foot first stage will target an autonomous landing on the Of Course I Still Love You drone ship in the Atlantic Ocean. SpaceX’s fleet of ships and the booster should return to Port Canaveral a few days later.

What Would a Quantum Internet Look Like?

In this episode, we’re tackling the question that’s on everyone’s minds: what will it take to have quantum internet in our home?

A quantum internet is in the works.

The U.S. Department of Energy recently rolled out a blueprint describing research goals and engineering barriers on the way to quantum internet.

The DOE’s latest blueprint for a quantum internet in the U.S. has four key milestones. The first is to make sure quantum information sent over current fiber optic cables is secure. Then to establish entangled networks across colleges or cities, then throughout states, and finally for the whole country.

But what exactly is quantum internet? There is no real clear meaning beyond “sending quantum signals back and forth,” and there are a few ways to go about doing it.

In February 2020, the Department of Energy announced they had sent two entangled photons over two separate 42 kilometer fiber optic loops and had verified they were still correlated when they returned. They hailed it as a milestone on the way to developing a national quantum internet.
