🚨🇵🇰 Pakistan soars toward tech sovereignty with fifth satellite in 'Space Vision 2040' push Over the past 16 months, Pakistan has launched five satellites. The country's media announced the fifth and most recent successful launch at the end of last week. All five satellites are designed for Earth observation. Primary uses include: 🔸 Monitoring crops and forecasting agricultural yields 🔸 Assessing soil condition and tracking fertilizer use 🔸 Detecting and controlling unauthorized construction 🔸 Planning transport networks 🔸 Conducting maritime border surveillance and port monitoring 🔸 Supporting geological exploration and mineral detection 🔸 Monitoring water and air pollution Satellite manufacturing: All five satellites were built by Pakistan’s domestic aerospace industry. Four of them are entirely indigenous innovations, while one was developed in collaboration with China. China’s role in the project: All satellites were launched using Chinese carrier rockets China also provided technical support, enabling Pakistan to access advanced space technologies while gradually strengthening its own domestic production capabilities Significance: The deployment of these five advanced satellites is part of Pakistan’s long-term national strategy, known as "Space Vision 2040." The overarching goal is to achieve full technological sovereignty — enabling Pakistan not only to manufacture its own satellites in the future but also to launch them independently from its own soil.

Pakistan's PRSC-EO3: an unusual orbit for an optical satellite Radar tracking via Leonardo Avella. Processed via COMSPOC SSA. PRSC-EO3 (visualized in cyan) launched April 25, 2026 on a Long March 6. It's an optical imager — but its orbit is curious. Most optical LEO satellites use sun-synchronous orbits (~97-105° inclination), which provide consistent lighting for imaging. PRSC-EO3 is in a 38° inclined orbit instead. This sacrifices global coverage and consistent lighting, but increases revisit rates over a specific latitude band: 20-40°N. That's India, Kashmir, and Pakistan. Now consider PRSC-S1 (visualized in pink), Pakistan's SAR satellite launched July 2025, sitting in a 41° orbit. Similar inclination, similar altitude — but their RAANs are ~175° out of phase. When one passes over South Asia in daylight, the other passes in darkness. SAR works day and night. Optical needs sunlight. The geometry appears to allow complementary coverage. We ran the access analysis [Image 1]. The SAR sensor (unconstrained) and optical sensor (daytime-constrained) together provide repeatable revisit across day and night. The gaps left by one are filled by the other. Then there's PRSC-HS1 — a hyperspectral satellite in SSO [Image 2], capable of detecting camouflage and identifying materials from orbit. Optical shows you the picture. SAR shows you the picture at night and through weather. Hyperspectral tells you what you're looking at. Five remote sensing satellites in 16 months [Image 2]. All launched by China. All with orbits favoring South Asian coverage. The stated missions are civilian. The orbital architecture appears consistent with a multi-modal ISR constellation.

🇵🇰🚀 Pakistan Completes EO-3 Launch, Accelerating Its Satellite Constellation Drive Pakistan has successfully placed its PRSC EO-3 Earth Observation Satellite into orbit, marking a significant step in the country’s expanding space programme. The satellite, developed domestically by SUPARCO, was launched from China’s Taiyuan Satellite Launch Center, underscoring a model of local manufacturing supported by external launch capability. EO-3 completes a three satellite Earth Observation series: ◽EO-1 (2025) ◽EO-2 (February 2026) ◽EO-3 (latest launch) Together, they form the backbone of a planned integrated Earth Observation system aimed at improving data availability and coverage. Pakistan now operates 5+ Earth observation satellites, with most deployed in the last two years, highlighting a noticeable acceleration in activity. Officials describe the programme as part of a broader shift: 📡 From isolated missions → to a coordinated satellite network From external reliance → to increasing data independence 🚀 From slow launches → to a structured rollout strategy The EO-3 mission also reflects continued technical cooperation with China, particularly in launch services. With additional satellites expected in the coming years, Pakistan appears to be moving toward a multi satellite constellation designed for regular, wide area monitoring. The direction is clear: a steady build up rather than a one off achievement.

How to See Microbes from the Sky — Yonatan Chemla on Hyperspectral Biology Scientists have studied bacteria under microscopes for 400 years. But Yonatan Chemla, a postdoctoral fellow at MIT, has developed a technology that lets us see microbes from a drone 100 meters in the air. In this episode, we discuss the emerging field of "hyperspectral biology," which uses hyperspectral cameras (first built by NASA in the 1980s) to detect molecules with unique light-absorption signatures. With this technology, you could engineer a microbe to sense a landmine, for example, and release a pigment in response. A drone could then spot that pigment from hundreds of meters away, thus identifying the locations of the landmines. By spraying other types of engineered microbes over a field, they could similarly map heavy metals, report on soil health, or find gold deposits. But almost none of this can happen in the United States. The EPA regulates engineered microbes as chemicals under the Toxic Substances Control Act, a 1976 law that never mentions biology, and the agency seems to have approved just one product through it. As a result, many of biotechnology's most useful ideas — microbes that break down plastic, sense landmines, or remove pollution from water — never leave the laboratory. This episode is much more casual than other podcasts I've recorded. We talked for many hours, into the early morning, and so I also feel like my lines of questioning are not as good as it could've been. The video quality is also not great; sorry!

Like it or not, Space is now a dangerous neighborhood. It's time to bring back the neighorhood watch. Today we're announcing Perceptor-- our new Space Domain Awareness spacecraft, and our first product line outside of comms. The message we've heard from Space Force these last few years has been loud and clear-- GEO is the most important orbit for military space. But that presents a problem, since there are few companies that can reliably and quickly deploy spacecraft to GEO. And it's not just for the military. The infrastructure operating in GEO provides communications, navigation and other critical services that billions of people rely on. It is well known that China and Russia are now launching spacecraft capable of approaching, inspecting and potentially interfering with other satellites. Based on the flight proven MicroGEO platform Astranis is already flying on orbit today, Perceptor brings monitoring and maneuverability to GEO and other high orbits. When an unfamiliar object begins maneuvering near a critical asset, operators need more than a dot on a screen. They need eyes in the sky they can rely on. Satellites in GEO operate across an enormous area nearly 36,000 kilometers up, that encompasses the entire Earth. Ground-based systems can’t provide the persistent, close-range awareness needed to understand exactly what another spacecraft is doing or why it may be maneuvering near a critical asset. As humanity expands outward from LEO and builds out the infrastructure layer higher up, it needs safety and security in place to protect it. That's why Astranis has answered the call. Ad astra per aspera.

Excited to announce UtilitySat, the world’s first multi-mission geostationary satellite, that we're launching at the end of this year. This is a first of its kind. And a new product line-- providing on-demand connectivity for disaster relief, bridge capacity, and other missions. We started Astranis to build something new: small communications satellites that provide dedicated broadband capacity for our customers. At the end of this year we’re launching four more of them on a dedicated Falcon 9 rocket, with many more to come after that. That launch of four satellites includes one satellite for Peru, two satellites for in-flight connectivity, and a fourth satellite that had been previously kept under wraps. Until now. Introducing UtilitySat, the Swiss Army Knife of satellites This is a new product— the world’s first multi-mission commercial GEO satellite, capable of conducting multiple fully-operational broadband connectivity missions. And it is just the first of many. We’ll plan to launch many UtilitySats in the years to come. UtilitySat can provide connectivity on standard Ku, Ka, and Q/V bands, and has the flexibility to dial in exact frequencies using Astranis’s proprietary ultra-wideband software-defined radio. It can also relocate dozens of times around the GEO belt over its lifetime. It does this using our unique on-board dual-propulsion architecture, which includes both a chemical monopropellant system and an electric ion thruster. A new mission every year, or every month When we first began development of UtilitySat almost 2 years ago, we had many different missions in mind. UtilitySat can serve as bridge capacity for a customer that is waiting for a dedicated satellite, as an on-orbit spare, or as extra, surge capacity that can be brought in to supplement the broadband service we’re providing to one of our customers. There are acute needs as well — a natural disaster can wipe out terrestrial connectivity over a huge geographic area. One of the top priorities for first responders and during disaster relief is reliable comms on the ground. With multiple UtilitySats on orbit, Astranis can bring in extra capacity on incredibly short notice. Capacity that is compatible with existing, low-cost GEO ground terminals. In initial conversations with customers for UtilitySat, we’ve seen huge demand — these customers often want to lease the entire capacity of the satellite once they learn what UtilitySat can offer. Customers need all the capacity they can get, and new capacity that can be deployed on short notice is a huge deal and a huge departure from traditional GEO satellites. We see a future where customers will be able to call up extra capacity on demand to augment their existing capacity needs, and we’re making that future a reality. US Government applications The first UtilitySat mission will be a commercial one, but we are seeing enormous demand from both from commercial companies and from our government customers. The US Government has unique needs — Combatant Commanders need to be able to task dedicated satellites to specific AORs at a moment’s notice — and surge communications would give them a new tool in their toolbox, helping them win even in a contested environment. And more broadly speaking our military leaders have said the one priority in national security space is to add resiliency to our fleets, using larger numbers of smaller, flexible, and maneuverable satellites so we’re not dependent on just a handful of huge satellites in GEO. UtilitySat shows that Astranis can do just that. Not traditional GEO satellites UtilitySat is only possible because of Astranis’s unique technology — including our proprietary software–defined radio. The flexibility of having on-board digital signal processing allows us to build a standardized satellite design, and move a lot of what used to be done in hardware, into software. UtilitySat uses the standard Astranis MicroGEO platform, adding more frequency bands and some new software capabilities to make maximum use of the available spectrum, no matter where the satellite is on orbit. Traditional geostationary satellites are designed to sit in one orbital slot for up to 20 years, with a set of frequency bands that is hardwired in at the factory. Their single mission must be predetermined many years before they are launched. Astranis does not build traditional GEO satellites. From day one we knew there had to be a better way, and we’re doing it.
