Tory Bruno departs ULA as CEO 3. A spate of recent global launches show uneven outcomes Snow FAA documents detail aviation risks from SpaceX's Starship test flight number 7. One CACI to acquire Arca Group expanding Space based sensing and intelligence. And today's guest is Greg Gillinger from Integrity ISR with our monthly Space intelligence chat about recent Russian space activities. Stay tuned for that in the second half of the show. Happy Tuesday everybody. Thank you for joining me and Happy Fastivus. Let's dive in, shall we? US based national security company CACI International has entered into a definitive agreement to acquire ARCA Group, a space and defense technology company focused on space based sensing, mission software and actionable intelligence. CACI says that the acquisition will be an all cash transaction of $2.6 billion. In its announcement, CACI says the acquisition expands its technology portfolio in support of national security missions, particularly in areas such as missile warning, space space situational awareness, space control and resilient communications. According to caci, ARCA brings deep expertise across space and ground based systems in real time sensing and decision advantage for US Government customers. It also adds that arca's work aligns closely with priorities across the space force, the intelligence community and missile defense agencies. The acquisition is subject to regulatory approvals, of course, but CACI does expect the deal will close in the third quarter of fiscal year 2026. Company leadership described the deal as a strategic expansion of CACI's technology portfolio, positioning the firm to compete more directly in large scale space sensing and intelligence programs as space becomes increasingly contested as an operational domain. According to newly reviewed FAA documents obtained by the Wall Street Journal, the seventh test flight of SpaceX's Starship in January 2025, which ended in an explosion and large debris field over the Caribbean, posed a greater risk to commercial air traffic than was publicly known. Three aircraft, a JetBlue flight, an Iberia flight and a private jet, all entered or came close to a temporary Debri no fly zone, with two of those aircraft declaring fuel emergencies while carrying a combined total of roughly 450 people. The Wall Street Journal reports that air traffic controllers scrambled to reroute planes as debris rained down across parts of the Caribbean for nearly 50 minutes. The FAA documents indicate that SpaceX did not immediately notify the FAA through its required failure reporting hotline. SpaceX did not make the notification to the FAA until 15 minutes after the starship vehicle disintegrated, delaying awareness of the debris field. Before that point, news of the explosion first made its way to air traffic controllers in Miami only due to pilots who actually saw it firsthand. For its part, SpaceX says this story from the Wall Street Journal was misleading and had incomplete information, and the company did decline to comment on the story. Earlier this year, it should be noted that federal officials halted an internal FAA safety review examining rocket debris risks and even as launch activity is expected to continue to rise significantly in the coming years. In an email obtained by the Wall Street Journal, an FAA official wrote that the FAA would deal with debris risk at a different policymaking level and added that, quote, the FAA will not hesitate to act if additional safety measures are required. And we of course have the link to the full exclusive story from the Wall Street Journal for you to read in depth now, from the Starship flight test earlier this year to a whole slew of launch attempts this week around the world. Let's take a look. First up in China, the first launch of the Chinese State owned Long March 12, a reusable rocket, did successfully reach orbit on December 22, an impressive milestone on the country's first attempt at reusing a launch vehicle. That said, the booster's landing attempt did fail. Earlier this year, Chinese commercial space company Landspace also attempted a landing burn of the booster of its reusable rocket, the Juque 3. So we should expect to see much more progress on this front in China in 2026. Also on Monday, Japan conducted another launch with its H3 small launch rocket to carry the Michibiki geolocation system satellite to its target orbit. However, a premature second stage cutoff resulted in mission failure with the satellite not reaching its target orbit. This was the seventh launch of the H3 rocket with the previous five launches all being successful. And lastly, in Brazil at Alcantara Space center last night, Korea's Innospace had its first commercial launch attempt with the Hanbit Nano space vehicle. However, that launch ended in failure when its rocket crashed about 30 seconds after liftoff, and that crash unfortunately sent the company's shares down by about 29% the next morning in trading. Space is hard Moving on now. Yesterday, United Launch alliance announced that its CEO, Tory Bruno is stepping down after 12 years of leading the company to pursue another opportunity. John Elbon is now the interim CEO of ula. On social media, Bruno posted this message it has been a great privilege to lead ULA through its transformation and to bring Vulcan into service. My work here is now complete and I will be cheering ULA on and we do wish Tory the very best and look forward to hearing what he is moving on to next. And lastly, the news about a failing SpaceX Starlink satellite is not new. The satellite in question suffered an anomaly last week, as you might remember, and is tumbling towards its deorbit future apace. The neat update about this though was that a Vantor Worldview 3 satellite at SpaceX's request managed to photograph the damaged Starlink satellite from orbit itself. Vantor, which was previously known as Maxar Intelligence, posted this update. Within hours we used our Worldview space capability to collect a 12 centimeter non Earth image that provided visual intelligence about the condition of the spacecraft. Worldview 3 was 241km away from the Starlink when when it collected this image which shows that the satellite is largely intact. And Vantor went on to add this by leveraging our non earth imaging capabilities and expanded collection capacity, we were able to move quickly and provide confirmation that the satellite was mostly intact, enabling SpaceX to assess potential damage. And the image of a satellite from a satellite is always quite a technical feat and this picture's certainly worth a thousand words and in this case it was taken very quickly too. So nicely done to the Vantor team. And that is it for this Tuesday intelligence briefing and it is our last intel briefing of 2025. We here at N2K do take the holidays off. I should note that we have a year in Review special episode that is dropping in your podcast feed tomorrow and I know I'm a bit biased, but it is a great episode. Definitely do not miss it because it's got reflections not just from me, but from the entire T Minus production team in conversation, and we will be running encore presentations of great chats from past episodes of T Minus throughout the end of the year. Our daily intel briefings will be fresh and ready for you, starting up again on January 5, 2026. In the meantime, on behalf of the entire T Minus team, I wish you a wonderful restorative holiday season and all the best in the new year. This episode is brought to you by State Farm.

We have actually split it into two parts for you. We will air the second half about Chinese space activity after the New Year. So in the meantime, here is part one of our chat.
C
For our talk today, I'll actually start with with Russia. Not heavy on the launch side so much, but some interesting on orbit activity from from a couple of their satellites. Okay, so you might recall a couple of months ago, I think it was, we talked about a little widget they had up in the we called it super synchronous orbit or in super geo orbit, which is actually technically incorrect. It's a geosynchronous orbit that's also highly elliptical.
A
Okay, yes, I do remember this. I do. I remember. I put a pin in that one and I said I think we might be going back to that at some point. So we're going back to it. Okay.
C
Yes. And that's going to be a common theme for today. So. So we have Cosmos 2589. That's the satellite that when Russia launched it in June of this year, it went into a geosynchronous. So at an orbital period of about 24 hours. But unlike a typical geosynchronous satellite, which has the average altitude above the surface of the earth of about 35,786km, this thing had it had an apogee. So its furthest point away was over 51,000 km, about 51,150 km above the surface of the Earth. Swinging its lowest point was just over 20,000 kilometers from the earth. Right. So it has a 24 hour period and it travels from east to west, west to east, remaining over the Russian mainland. And the interesting thing with 2589 is it was built by some companies that were also instrumental in what we've seen in low Earth orbit with some of their, what we call nivellier satellites, which are these inspector satellites. Right. So the one satellite goes up and it has a sub satellite that comes off and it does, you know, it's basically an observer satellite that will inspect its parent or it could inspect another satellite if it wanted to. And then in the low Earth orbit cases, we've seen that sub satellite actually release projectiles at high velocity. U.S. space Command is kind of deem that as a weapons test. So same folks that made those Navellier satellites, which are all in low Earth orbit, were partially responsible for developing and building this Cosmos 2589. So when it went up, a lot of folks noticed hey, that this is unusual. So it went into this unusual orbit and it was built by this team of folks that has some experience in developing at least inspection satellites, we'll call them that for now.
A
Right. And I remember when we, when we talked about this some months ago, it was keep an eye on it because it might do something like Russian nesting doll style in addition to this unusual orbit. So what have we seen?
C
Yeah, so it did, it did do something. It actually hatched. Sorry, the Astro guys will get off me for saying that. It released a sub satellite which we called a number of different things until we finally settled on Cosmos 2590. So 2589 is the mothership, if you will. Cosmos 2590 is kind of the dog.
A
The baby. Yeah, the baby, the daughter. Yeah.
C
So 2590 was released from 2589 just a couple weeks after. So after 2589 was on orbit. So 26th of June, 2590 is noticed.
A
Right.
C
And over the next couple of months we see 2589 really doesn't do much maneuvering. It stays in this, in this geosynchronous elliptical orbit, just kind of doing its thing. But we see a lot of maneuvering out of the, the offspring satellite, I'll just call it that. So 2590 is, is doing a lot of RPO activity, the rendezvous proximity operations with, against 2589. So we expect, we assume that that's doing some sort of inspection missions very similar to what we've seen them do test in, in low Earth orbit. We did not see any of those high velocity third object projectiles released from from any of these satellites. So that's, that's a key difference. But we, we obviously know that 2590 is a highly maneuverable object and they again looks like they conducted several tests. And then from the. So that was in June when 2590 was released. So we have a number of different RPO events between then and the 14th of November and from the 2nd to the 14th of November this year. So just last month they got closer than what we'd seen in the past. And there's some margin of error in all of the figures that I'm throwing out because these objects are very far away from the Earth, so accuracy can be a concern.
A
So between the mother and the daughter, or the parent and the offspring, whatever you want. Got it? Yep.
C
Between the 2nd through the 14th of November, it really looks like they're doing a final operations test because they kept those two things very close together. I say close, I'm talking, it looks like less than two kilometers apart, which.
A
Yeah, close. Close in satellite terms.
C
Yes, exactly, exactly. And so we hadn't seen that before. And then after the 14th, we saw 2589 make its first maneuver in quite some time and it started to separate. So two week period of this kind of intense RPO activity followed by 2589 making a maneuver that over time it became a repetitive pattern where we see it begin to lower its apogee and increase its perigee. So what it's doing now is it looks like it's slowly creeping back to geosynchronous orbit. Right. So without this crazy elliptical piece to it. Right. So as perigee and apogee get closer to one another, your eccentricity goes down you closer to that perfect circle. Right. So an ex. Interesting 0 would be a perfect circle. Right. Now they're around just north of point three. So before I mentioned, they were about 2km apart for a couple of weeks now at the end of the month they were over 3,000 kilometers apart. Right. So they're separating fairly quickly. We're not seeing the same eccentricity decrease from 2590 at all. So you know those, they're continuing to test it. We have some, seen some maneuver, so it's still live, but it's, it's no longer interacting with, with 2589. Russia has launched other satellites into similar orbits to, to these two in the past. Those were communication satellites and it's taken about three to six months for those satellites to actually get to their operational orbits, which were more traditional, your more traditional geosynchronous orbits. So we're expecting this to be about the same. 2589 has a rather large bus and the thrusters that we think are on there aren't necessarily all that powerful. So we're expecting it to be closer to the six month, maybe even a little bit longer than six months before it finally settles into geosynchronous orbit. And maybe I shouldn't use some term, settle. I don't know what it's going to do once it gets into that geosynchronous orbit, how Russia intends to use it. You know, is there another simple, another daughter on board?
A
Right.
C
Is there more than one of these sub satellites similar to 2590 on board? How does Russia intend to operate? Is it going to kind of traverse the geo belt like some of the other inspector satellites that we track, or is it going to be more like the Russian Luch Olymp satellite, which tends to go to one target satellite, we'll call it target satellite, hang out for several months, and then move on to another satellite.
A
Oh, so it's not. Its job might not be done. It's not. Hey, I've done the inspection. We just don't know really.
C
Yeah, probably not. I mean, I'm thinking that they did some testing in this geosynchronous, highly elliptical orbit for a lot of reasons it remained over Russia. It also makes it really tough if you're operating all the geo inspector satellites that we know of are in geosynchronous orbit. Right. So if you're operating at 51,000 kilometers, you're 20,000 kilometers above the geo, the typical geo belt. So the ability to do any sort of imaging or characterization of the Russian activities with these two satellites is, is challenged by those distances. Right. You know, now that they're moving back towards once they join the geosynchronous belt, then Inspector satellites have a much better opportunity to take a look and see what this thing actually may be capable of. Okay. But we don't know if, if Russian plans to what, what their plans are or how they plan on using it, but it's likely something we'll be able to observe. So I think we have a reasonable chance of seeing what they're up to with this. But I, I think for now it's going to be kind of in this pattern of every 12 hours it does what we call in track burns. Right. So it changes its velocity, it increases its velocity at apogee in order to raise perigee, and then it decreases velocity of perigee to reduce apogee, and it's just going to flatten it out a little bit. Several months. Yes. So they yeah, kind of in this jelly bean looking orbit right now and that jelly beans narrower, narrower. So far the, the apogee's dropped just over 3,200 kilometers and the perigees increased about that same number since November 14th.

All right, Greg, we're going to have to leave it there for this month, but Happy holidays to you. Happy New Year and thank you so much for all this information that you've been sharing with our audience this year. I have learned so much from you. I've learned a lot about orbital mechanics through you too. So I really appreciate all the education and I can't wait to learn more from you next year too.

See Ford.com BlueCruise for more details. Welcome back. And I mentioned it a bit earlier today, but we here at N2K are taking an end of the year break with our daily intel briefings after today's show. And we're not the only ones who take the time off. I'm sure many of you listening might be doing the same. And if you're not, and you wish you were, I am sorry, I don't mean to rub it in. Well, the NASA scientists who work with the Curiosity rover on Mars will also be taking a break and it just happens to be with good timing for the holiday season. But in this case, Curiosity is not taking time off for festivities. It is actually conjunction time, meaning Earth and Mars cannot see each other as the sun gets between us. This happens every two years or so and it just so happens that the upcoming conjunction for Earth and Mars goes from December 27th to January 20th. Nice timing. Communications between our two planets gets really garbled by the sun's obstruction, if not completely obstructed. So. So it is best to take a break during that time and not plan on sending any commands to these very precious rovers of ours. As a result, Curiosity has been safely parked by the NASA team for its conjunction break when comms goes dark and in essence Curiosity will disappear behind the sun while Curiosity is parked. Background observations will continue, but nope, there will be no roving until then. To the NASA science team, we wish you all the best and hope you enjoy your well deserved break and and I can't help but wonder what the rover will daydream of while it is idle. Maybe I'll mull it over on my own holiday break in Curiosity. We will see you again soon on SOL4787. And that is T minus.
