Space Force needs to prepare for a new Cold War in Earth’s orbit

“The bottom line,” said retired three-star general Chris Bogdan, “is that we want to learn how to fight in space. Just as we know how to fight on air, land, sea, and, in some respects, in cyberspace. Space is a new warfighting domain. Our job is to try and help the Department of Defense to become space warfighters.”

Bogdan knows a thing or two about militarized combat. Over a 34-year career in the U.S. Air Force, Bogdan rose from a test pilot, flying no less than 30 different aircraft types, to the rank of lieutenant general. For the last five years of his career, before he retired in July 2017, he was program executive officer for the F-35 Joint Strike Fighter Program for the Air Force, U.S. Navy, U.S. Marine Corps, and 11 allied nations. He has one of those grizzled, no-nonsense voices which suggests that he’s forgotten more about warfighting before breakfast that day than you’ve ever known in your entire life. On balance, that’s probably not a bad guess.

Right now, Chris Bogdan is worried about satellites. But not for the same reason that many people are. Recently, satellites have gotten a bum rap. Astronomers have sounded the alarm regarding the plan of individuals like Elon Musk to launch enormous, sky-blotting mega constellations of satellites. Bogdan doesn’t seem to be so tied up in knots about extra stuff being shot into space, however. Instead, he’s far more concerned about the stuff that’s already in space being shot down. Or, at least, being tampered with.

He’s particularly uneasy about things called hunter-killer satellites, deployed by one of the United States’ “pure adversaries,” being used to screw with America’s network of “space assets.”

A new kind of threat

A hunter-killer satellite represents a new kind of threat. In a paper published in the journal Scientific Reports in 2018, researchers from the Australian National University describe a hunter-killer satellite which can fire jets of plasma to blast objects out of orbit. They suggested that such a satellite could be used to help clean up space junk; shooting it down until it eventually disintegrates in Earth’s atmosphere. But such a tool could be used for more malicious purposes as well. A hunter-killer satellite might damage or purposely knock off-course a crucial active satellite, thereby negatively impacting its ability to operate.

“What we’re most concerned about is what we call conjunction,” Bogdan said. “That’s a space term describing two things colliding in space. But you don’t need to actually hit something in space to affect it or reduce its capability. You can fly a hunter-killer satellite close enough to a satellite that you can disrupt maneuvering or its electro-magnetic field to do a host of different things.”

“You don’t need to actually hit something in space to affect it or reduce its capability.”

How far away from deployment does he think these hunter-killer satellites, developed by those who don’t have America’s best interests at heart, might be? “I believe they’ve already been deployed,” he said.

Another possible threat is an anti-satellite missile fired from the ground. Several nations, including China, India and Russia, have demonstrated such weapons as a show of force. “We know that our adversaries have [them],” Bogdan said. “They’ve proven it.”

The effects of taking out a satellite

In a James Bond movie like 1995’s GoldenEye, satellites are used to threaten the Earth by blasting targets from orbit using something like an electromagnetic pulse weapon. However, while that might look more sexily destructive on screen, a satellite which destroys other satellites has the potential to be just as harmful, perhaps even more.

From a military perspective, today’s satellites offer a host of critical use-cases. They carry out worldwide sensing and imaging. Space-based communications are also crucial for our ability to pass information around the world, whether that’s in the form of voice comms or data. Then there is GPS, the Global Positioning System, which lets people (including the military) gain quick and accurate information for estimating the speed, time, and exact location of objects or humans. Any one of those three — sensing, communication, or GPS — gets disrupted, Bogdan said, and the United States is put at an enormous “warfighting disadvantage.”


Such an offensive action has, fortunately, never been taken. But we have some idea of what the effects might be. In January 2015, the U.S. Air Force took one of its GPS satellites, out of a constellation of a couple dozen, offline. Somehow a fractionally wrong time was accidentally uploaded to the others. The results caused 12 hours of severe problems. Global telecommunications networks risked failing. Radio equipment belonging to police, fire and EMS departments in parts of the U.S. stopped working. BBC digital radio was knocked out for a couple of days for many people, and an anomaly was detected on electrical power grids. All from a time discrepancy of just thirteen millionths of a second.

Knock out one military satellite used for a crucial task like GPS or communications and the results would be extremely problematic. Knock out several in quick succession and it would be nothing short of a disaster.

The Outer Space Treaty

You might, of course, ask why this issue hasn’t been more heavily publicized before. After all, the United States launched Explorer 1, its first satellite, into space on 31 January 1958. Since then we have ramped up our reliance on these orbiting objects with every passing year. Today, there are in the order of 2,000 active satellites in orbit belonging to both governments and private industry. More are going up all the time.

The answer is that people did worry about this risk, although never before have we relied on our constellation of satellites to quite the extent that we do today. However, space was designated off-limits by those in power. On 27 January 1967, two-and-a-half years before the first moon landing, delegates from Moscow, London and Washington signed an agreement called the Outer Space Treaty.

Today, there are in the order of 2,000 active satellites in orbit belonging to both governments and private industry.

This multilateral convention deigned to lay out guidelines that would quash any disputes about the future allocation of spatial and material resources found in outer space. The other objective of the Treaty was to prevent the Cold War arms race from spreading into space. In doing so, it solidified a previous 1963 treaty prohibiting nuclear explosions in outer space; expanding this to cover other military uses of space. The agreement, largely unchanged, has stayed in place for the 53 years since.

“For decades, the United States believed space was a sanctuary,” Bogdan said. “We didn’t look at space as a war-fighting domain, and we felt that no-one would [ever] threaten our space assets.”

But he’s no longer convinced that such an agreement is being upheld. “We have critical space assets and capabilities today that for decades we thought didn’t really need to be protected. Well, our adversaries didn’t think that way,” he continued. “Our pure adversaries, China and Russia, for quite some time now have recognized that space is — and will be — a war-fighting domain. They’re going to try to limit our space capabilities in an asymmetric kind of way if we ever get into conflict with them.”

Predicting attacks in advance

So what’s the answer? Reducing our reliance on satellites isn’t really an option. While backup systems are important to build and develop, satellites are simply too valuable to avoid relying on. Since leaving the U.S. Air Force, Chris Bogdan has joined Booz Allen Hamilton, a strategy, technology and engineering consulting firm. Bogdan heads up the firm’s aerospace business, which includes developing “transformational solutions” for the likes of NASA and the Department of Defense.

At present, he said, the firm is working to develop artificial intelligence (A.I.) software which can be used to provide early warning notice about the movement of potential hunter-killer satellites as well as anti-satellite missiles. These systems, which employ data analytics and machine learning algorithms trained on some 40 million data sets of satellite movements, can reveal whether a satellite is being manipulated. It can also predict where other satellites are headed to offer up to a week’s notice about the trajectory of potential threats.

“Our models let us look five to seven days ahead of maneuvering satellites,” he said. “[That’s important because] with everything in constant motion it might not immediately be apparent what that satellite is going to go after.”

Once the system has figured out everything that’s at risk as satellites move into different orbits, it then generates a list of potential actions that can be taken. The risks and rewards of these actions are calculated and a score assigned to them between 0 and 100. The challenge, Bogdan said, is that each time you move a satellite it shortens its operational lifespan. Moving a satellite out of its regular orbit may also stop it from being able to properly carry out the job it was designed to do. Like a defensive boxer, the goal is therefore to react to possible threats without expending more energy than is absolutely necessary.

“Ultimately you want a course of action that will protect your assets, while at the same time minimizing all those bad things,” he said.

A new era of space war

Booz Allen’s system is currently in development. Once it is complete and the infrastructure is in place to support it, Bogdan hopes that it will be adopted by the recently reactivated United States Space Command, who will incorporate it into their space war fighting center, the National Space Defense Center, in Colorado. They will then be able to use it to identify potential threats and react accordingly.

The U.S. Space Force hasn’t exactly been expansive on how it will defend America against space-related threats. Bogdan was cagey about detailing the “certain capabilities” that the Department of Defense has available to it in this domain. Such strategies, he said, might include building more reactive satellites along the lines of the defensive capabilities of Bogdan’s beloved F-35s, which can react to threats automatically without the pilot having to tell the aircraft to do so.

Another approach could involve going “on the offense to play the defense” by deploying its own hunter-killer satellites (hunter-killer-killers?) to conjunct or intercept with adversaries.

Right now, Bogdan asserted, the U.S. is “kind of in catch-up mode” when it comes to the subject of space warfighting. Thanks to the work of companies like Booz Allen, we could be in for a whole new era of militarization of space. Needless to say, if what he hypothesizes turns out to be accurate, we’re in for a whole new era of futuristic warfare. For better or worse.

“What needs to evolve now are some rules of engagement about what constitutes a risk and what constitutes an act of war,” he continued. “Lots of people are thinking about that, but I don’t think it’s very mature.” One thing’s for sure, though. “The rules up there are going to be very, very different to what they are [down on Earth],” he said.


Sennheiser GSP 670 headset review: premium price, subpar performance

The search for a new headset can really get frustrating. Sure, there are a million options on Amazon for under $50, but when you want something premium, where do you start? If you’re looking for the best possible audio quality, you start with the Sennheiser GSP 670 and hope you can find it on sale because these things don’t come cheap.The GSP 670 is a premium headset with sound quality and a price tag to match. Launching at $350, you’re paying for the Sennheiser name and quality. We’ve tested multiple Sennheiser headsets throughout the years and have almost always come away impressed. That’s the same story here.The first thing you may notice about this headset is just how big it is. It looks big before you pick it up and it feels big once you put it on. Coming in at just shy of 400g, it has the weight to make those extremely long gaming sessions taxing, but luckily Sennheiser included one of the best headbands I’ve seen in a headset yet. It’s big and comfortable without looking too ridiculous.The earcups are equally nice with large plus fabric cups that will keep your ears away from the driver covers. If you prefer leatherette cups you’ll want to find another option, but I did find these to be one of the most comfortable headsets to just sit and listen to music on. The clamping force is just right (although uneven; more on that later) and the earcups provide a wonderful seal to keep the noise of the world away from your ears.One the outside of the headset, there’s a small tactile wheel to adjust chat volume if you’re using a gaming console, a large volume knob, and a multifunction button that will provide audio prompts for battery level and put you into pairing mode when you hold it down. The only thing we’re missing here is a physical switch to move between Bluetooth and 2.4ghz connection standards, and we’ll tell you why that matters in a bit.The microphone is on the left side of the headset and provides a nice tactile click when you flip it all the way up. This is how you mute your microphone and comes in handy when you need to have a quick conversation and get back to whatever you were doing before.I wish I could report that the microphone provided better audio quality but I was pretty disappointed. It’s been a struggle to find a wireless headset that really gives great performance in this area (I’m guessing there’s a bandwidth issue) and the Sennheisers fall disappointingly short. I think they sound much the same as every other headset released in the last decade, which isn’t saying a lot.Both Bluetooth and 2.4ghz connection standards are here. Plugging the USB dongle into my computer, the headset paired almost instantly and opened up a world of opportunity to tune through the Sennheiser app. There are options to tune your EQ, how the microphone sounds, and even provide a noise gate in case you have a noisy background. I didn’t find much difference in how the microphone sounded using these options so hopefully, they continue to be tuned in future updates.The sound that comes through these headphones is a completely different story. This has been one of the best audio experiences I’ve had in my time reviewing tech. I’d put it up there with the Sony WH-1000xm3 in terms of enjoyment. Where Sony offers amazing noise cancelation, the Sennheiser GSP 670 takes the crown in terms of audio quality.I found music pleasingly bass-y without feeling like I’m slogging through the mud just to listen. Mids are very clear while highs are crisp without being piercing.I just wish I enjoyed wearing these more. I can’t overstate how heavy these things are. At just under 400g, they’re one of the heavier headsets I’ve tested and it can be exhausting during long sessions. With 16 hours of battery life, those sessions can last all night, but you’ll need breaks.Additionally, I don’t like wearing these because of how the cups sit on my head. While the cups themselves are large enough that my ear doesn’t touch anything, the clamping is uneven and annoying. You can use the sliders in the headband to adjust your clamp, but I always end up with more pressure on the bottom of the cups than at the top.Frankly, these don’t look great and certainly don’t look like something I’d pay over $300 for. They’re big and bulky with muted colors and an … aggressive? design. I’m not entirely sure what to call this design language but there are definitely better-looking options on the market. This won’t matter to some, but for those who do care, it’s a bit of a killer and makes the cost harder to justify.ConclusionThere are always trade-offs when you’re using a wireless headset. Sennheiser smartly did not skimp on the audio quality and if you’re looking for a wireless headset that sounds great, this is definitely where you want to start. I put it at the top of the list in that respect.But, where it falls apart is pretty much everywhere else. Tradeoffs become pretty obvious when you use these for more than a few hours.Yep, they’re built solidly and the plastic design means they’ll hold up to some abuse. But, these look cheaper than competing options like the Astro A50s and Arctis Pro Wireless. Plus, as I’ve said a few times, they’re heavy.It’s awesome that they have both 2.4ghz and Bluetooth standards. But there’s no way to manually switch between them and the second that your computer plays audio via the USB dongle, the Bluetooth cuts out completely. If you’re using these to take a phone call or listen to music on your phone and you accidentally click on a YouTube link on your computer, say goodbye to your audio. This would be an easy fix with a manual switch and we hope to see that in a future revision.Best over-ear headphones (spring 2020)I can’t state enough how crappy the audio from the mic is. Maybe I’m spoiled by streamers who invest hundreds and hundreds of dollars into their audio equipment, but this sounds like every headset I’ve heard the last decade of gaming and that’s pretty disappointing.If your voice quality matters to you at all, I’d suggest getting a standalone mic. But you have to ask yourself if you’re grabbing something like a Blue Yeti, is there a justification for the GSP 670 when you can buy a wireless headset for far cheaper?I know it probably looks like I hate the Sennheiser GSP 670 but I don’t. In true dad fashion, I’m not mad, I’m just disappointed. While they’re best in class in terms of audio quality, the things they miss on are a killer and make them harder to recommend over other competitors.After a bit of searching, I’ve found the Sennheiser GSP 670 around $300 and sometimes cheaper on sale. I think if you can find these cheaper than that, go for it. Your ears will thank you. At full price, they’re a tough sell.Buy the Sennheiser GSP 670 at Amazon
