Tres estrategias para evitar que nos vigilen con reconocimiento facial

The first spacecraft that can service satellites to extend their life launched today

Up until now, commercial satellites have essentially been disposable. Even the massive, multi-ton ones that can have service lives spanning a decade or more eventually just become so much space trash once they’re out of fuel, or they experience some kind fo terminal mechanical failure. A new spacecraft built by Northrop Grumman and launched aboard a Russian Soyuz today (via Space.com) could change all that, however.

The MEV-1, as its known, is a satellite service spacecraft, which has the specific mission of meeting up with Intelsat 901 in orbit and lending it use of its orientation thrusters to put it back into an ideal target orbit – thus extending the useful life of the 18-year old satellite by as many as five years. Once it has succeeded in putting Intelsat 901 back on track, it’s very possible the MEV-1 could do the same thing for yet another orbital satellite running low on its own propellant supply.

In fact, Northrop Grumman says that the spacecraft is itself designed for a 15-year useful life, and can dock and undock multiple times, providing “well in excess of” 15-years of mission extension to geosynchronous satellites around 4,400 lbs in size while docked with said satellite.

That should mark a new era for commercial satellite operation, leading to further decreased operating costs, and therefore more access for startup and smaller companies to take part. Northrop’s MEV-1 is basically a space tug, but even that can as much as double the life of some geosynchronous satellites – which means a lot more potential revenue for not too much more cost, if the MEV-1 serves multiple customers who share the cost of its development and launch. Think of it as satellite servicing-as-a-service, or a SsaaS model for space tech companies.

Other satellite servicing projects are in the works, and could benefit companies like Orbit Fab, the so-called ‘gas stations in space’ startup that was a finalist in our Battlefield competition at TC Disrupt last week. Orbit Fab is working on a simple refuelling system for satellites to use in space, so that the servicing craft wouldn’t need to actually dock and propel the satellite it’s working with, just connect and transfer some fuel. Other potential business opportunities could lead from in-space commercial orbital spacecraft servicing, including upgrading satellites with new modules and sensors from different customers to maximize the return on the investment of their original design, build and launch.

Facebook sure does love free $peech

Ensuring politicians in the 2020 election stay truthful is hard work, so Facebook has decided it’s going to sit this one out.

Joe Biden’s campaign team sent a letter to CEO Mark Zuckerberg, COO Sheryl Sandberg and global elections policy chief Katie Harbath that essentially called on the company to take down a Trump campaign ad that made debunked claims regarding the Biden family’s relationship with Ukraine. Facebook responded to that letter today with their own letter to Biden saying that the company’s policies prevented it from making judgment calls on the veracity of speech in political advertisements. The New York Times has a full run-down of the situation.

Facebook isn’t alone in this manner; Fox News is remaining fair and balanced on the issue as well. CNN refused to run the ad.

Political campaigns are messy, so America’s largest content company — with more content moderators than any publication in the country — is leaving it to the free press to debunk what it’s getting paid to broadcast. But it’s not that Facebook wants to keep raking in stupid amounts of advertising dollars, no, it’s that the company is grounded in a “fundamental belief in free expression,” they say.

Here’s a quote from the company’s letter to Biden’s team: “Our approach is grounded in Facebook’s fundamental belief in free expression, respect for the democratic process, and the belief that, in mature democracies with a free press, political speech is already arguably the most scrutinized speech there is.”

I’m sorry, what? Facebook’s “respect for the democratic process” should raise eyebrows given how its products have been used in some highly publicized scenarios, but how does a platform that’s been abused so much to the detriment of democratic processes feel like it deserves to rattle that phrase off as another PR talking point?

Here’s the rest of the letter:

If Facebook just wants to allow politicians to spout mistruths and conspiracy theories without fact checks on its platforms as status updates from their personal pages, then some of these claims could be taken more seriously, but Facebook is getting paid to push these messages to its users. It’s algorithmically deciding where these messages go based on parameters set by the campaigns via a system it designed.

Before you sound off, yeah, political advertising isn’t anything new. I am well aware that TV channels and newspapers have carried messy attack ads and hauled in the advertising revenues for decades, but Facebook is a platform designed around scale. Scale has allowed the company to tap massive revenue streams, but it’s also opened up the company to critiques. The company has learned to respect this scale after sizable amounts of external pressure were applied, but they’ve always defaulted to dated comparisons when it’s profitable to them.

Newspaper and TV political ads are painted with a wider brush and are subject to more stringent laws, but there’s a responsibility in Facebook’s precise ad-targeting that the company still doesn’t seem to respect. The company has the tools to push out judgment calls on content, and it could still do so on a case-by-case basis. Some truths are buried in more nuance than others, but by painting all political claims in its same bath of indifference to truth, Facebook is abusing its scale and creating a platform where a politician’s speech is exempt, as if political leaders aren’t the ultimate primary sources on politically contentious matters.

Political advertising legislation is going to take far too long to catch up to the current landscape of technology platforms — it would be nice if we could trust Facebook to stay at a moral forefront that isn’t legally mandated. Twitter and YouTube aren’t immune to this same criticism either, but Facebook is operating in broad daylight, believing that they can reverse engineer a free expression mission statement to prevent responsibility-free revenues from leaking out.

Virgin Orbit plans to launch first commercial small satellites to Mars

The Richard Branson-backed small satellite launch operation Virgin Orbit wants to be the first to dedicate a mission to bringing commercial CubeSats to the “Red Planet,” the company announced today. Working with Polish satellite company SatRevolution, Virgin Orbit has established a consortium along with a group of Polish academic institutions to jointly work on at least one, and as many as three, small satellite launches to Mars, with the first expected to happen as soon as three years from now.

The consortium is working to follow in the footsteps of the NASA Jet Propulsion Laboratory’s MarCO mission from 2018, which saw two smaller satellites successfully launched to Mars. The group’s early studies have suggested that even satellites as small as 50 kg (around 110 lbs), or potentially even smaller, can provide meaningful and useful research, including imagery collection, from both Mars and its orbiting body, Phobos. These satellites could provide key info about the atmospheric composition of Mars, or even scouting for underground water, Virgin Orbit says.

Warsaw-based SatRevolution has experience in the commercial space industry, and in April this year sent Poland’s first commercial nano satellite into orbit. The universities involved, which include the AGH University of Science and Technology, Wroclaw University of Science and Technology and many others, all have experience in space industry research, as well. The plan is to launch the spacecraft developed by the universities and SatRevolution aboard Virgin’s LauncherOne rocket, which takes off from a converted 747-400 Virgin has retrofitted for the process.

Virgin Orbit is aiming to have its first orbital rocket launch later this year, and is currently going through the final round of testing before that happens. The company ran a successful drop test earlier this year, during which it let a non-functional rocket fall from the wing of the 747 launcher aircraft in a key test, and it has been signing contracts to launch from the U.K. as early as next year.
