The Aerospace Corporation added 35 roles in seven days — and almost none of them mention DiskSat

What Is DiskSat and Why Does It Matter

On December 18, 2025, a Rocket Lab Electron rocket lifted off from Wallops Island, Virginia, carrying four flat, round satellites that looked nothing like the boxy CubeSats that have dominated small spacecraft design for two decades. Each DiskSat measured 40 inches across and just one inch thick, closer in proportion to a dinner plate than a shoebox. The launch, part of the U.S. Space Force's STP-S30 mission, marked the first orbital demonstration of a form factor that NASA, Space Systems Command, and The Aerospace Corporation bet could change how small constellations get built and deployed.

The problem DiskSat addresses is simple: CubeSats work well for what they are, but their compact, rectangular shape imposes hard limits. A standard CubeSat offers a small surface area, which caps how much power its solar cells can generate and how large an antenna or sensor aperture it can carry. For missions that need high power, wide signal coverage, or room for bulky instruments, engineers have had to accept tradeoffs or bolt on deployable panels that add mass, complexity, and failure risk.

DiskSat keeps the standardized containerization that makes CubeSats cheap to launch (the rideshare-friendly dispenser model, the off-the-shelf subsystems) but replaces the cube with a disk. The first demonstration units are one meter in diameter and 2.5 centimeters thick, with an internal volume of nearly 20 liters. That's roughly equivalent to a hypothetical 20U CubeSat, but spread across a flat plane instead of packed into a box. The surface area is large enough to host over 200 watts of solar cells without deployable panels, and the wide face gives antennas and sensors room that a CubeSat simply cannot offer.

The flat layout also changes how the spacecraft gets built. Components sit in a two-dimensional arrangement inside the disk, which The Aerospace Corporation says makes them more accessible during assembly, integration, and test. The structural bus is an aluminum honeycomb core with carbon fiber face sheets (lightweight, stiff, and thin enough that multiple DiskSats can be stacked in a single dispenser canister). The first flight carried four; the modular dispenser is designed to scale to 20 on a single launch.

Each of the four demonstration DiskSats carries electric propulsion, giving them the ability to maneuver between orbits after deployment. The mission's objectives include testing that maneuverability, validating solar performance, and demonstrating sustained operations in very low Earth orbit (below 300 kilometers), where the disk's low-drag orientation (flying face-on to the direction of travel) could let satellites operate at altitudes that would quickly decay for conventional shapes.

The partners behind the program reflect its dual-use potential. NASA's Small Spacecraft & Distributed Systems program, based at Ames Research Center, funded and manages the technology demonstration through its Space Technology Mission Directorate. The Aerospace Corporation, headquartered in Chantilly, Virginia, with its primary small-satellite engineering work in El Segundo, California, led the design and development. The U.S. Space Force's Rocket Systems Launch Program funded the launch, and the Department of Defense Space Test Program funded ground operations. Rocket Lab provided the Electron launch vehicle.

Four satellites are in orbit. The dispenser mechanism has been tested. Now the question is whether the data from this demonstration convinces operators (government and commercial) that the disk is worth building around.

The Hidden Hiring Surge Behind the Platform

The Aerospace Corporation doesn't publicize headcount figures for specific programs, and DiskSat is no exception. But the job postings tell the story the press releases don't. Zero G Talent's board shows 35 Aerospace roles added in the past seven days alone, a pace that points to sustained, program-driven hiring rather than backfill.

The roles fall into distinct clusters. At the entry level, the 2025 Space Systems Engineer listing on Built In targets recent graduates for Colorado Springs, El Segundo, and Chantilly, with a pay band of $80,000–$90,000. The job is housed in the Space Control and Awareness Department, which handles space domain awareness, orbit determination, and sensor analysis — all capabilities a flat-satellite constellation would need to operate and defend. The requirements are specific: modeling and simulation experience, algorithm development, proficiency in Python or MATLAB, and background work in filtering algorithms for orbit determination and positioning, navigation, and timing.

A step up, the Space Systems and Orbit Determination Operations Engineer role on LinkedIn requires four years of experience and pays $100,300–$150,400. This position lives in the same department but carries heavier analytical responsibility (Kalman filtering, target tracking, navigation analysis, and direct support to space surveillance missions). The overlap with DiskSat's operational needs is hard to miss: a constellation of ultra-thin satellites would demand exactly this kind of orbit determination and tracking work at scale.

Then there's the Space Electromagnetic Warfare Systems Engineer, posted at two levels: Project Engineer (eight years minimum, $129,000–$249,600) and Sr. Project Engineer (twelve years). This role supports Mission Delta 3, the Space Force's electronic warfare delta, and requires active TS/SCI clearance with SAP access. It signals where Aerospace is placing its most expensive bets: protecting satellite constellations from directed energy threats, jamming, and electronic attack.

The recruitment PDF Aerospace circulates at career fairs lists the disciplines the company is hiring across: aero/astro, AI/ML, electrical engineering, optics and imaging, quantum technologies, software engineering, systems engineering. DiskSat isn't just a mechanical design problem — it's a systems integration challenge that pulls from nearly every one of those categories. A flat satellite has different thermal profiles, different power constraints, different antenna geometries, and different manufacturing tolerances than a conventional bus.

What's harder to quantify is how many of these roles are explicitly tagged to DiskSat versus adjacent programs. Aerospace's job listings don't name specific platforms. They name departments, mission areas, and clearance levels. The company's FFRDC structure means most work is classified or customer-restricted, so the public-facing postings are deliberately vague. But the concentration of Colorado Springs-based roles (the city closest to Space Force operational commands and the bulk of the company's space control work) suggests the hiring surge is anchored to programs that live in that building.

The compensation structure is consistent across levels: base pay bands set by grade, a 401(k) with 8–12% company-paid contributions that vest immediately, and standard federal-contractor benefits. For engineers weighing offers against Northrop Grumman or Rocket Lab, the trade-off is clear: Aerospace pays below the top of the defense primes but offers the clearance pipeline and mission access that commercial companies can't match.

Why Flat Satellites Change the Talent Equation

The Aerospace Corporation's DiskSat program doesn't just demand a new kind of spacecraft. It demands a new kind of engineer — one whose training lives at the intersection of disciplines that traditional satellite programs keep carefully separated.

A CubeSat, by specification, is built around a 10 cm cubic unit with standardized dispenser interfaces, off-the-shelf component bays, and a well-documented set of mechanical, electrical, and thermal requirements. NASA's Goddard Space Flight Center handbook GSFC-HDBK-8007 lays out a tiered approach to CubeSat mission success that assumes these constraints, from "Do No Harm" missions requiring as few as 100 hours of system-level testing to Class C missions demanding 1,000 hours and full part qualification. The CubeSat Design Specification from Cal Poly SLO defines the envelope, the mass limits, the rail geometry, and the deployment switch requirements. Engineers entering CubeSat programs inherit a mature ecosystem of standards, vendors, and verification processes.

DiskSat throws out the box.

The structural problem is fundamentally different. A flat satellite doesn't have the internal volume of a 3U or 6U CubeSat to distribute components across stacked boards and chassis walls. Every subsystem (power, communications, attitude control, payload) must be integrated into a planar geometry. That means structural engineers can't rely on the standard aluminum box-and-rail architecture that the CubeSat Design Specification codified. They need to think about load paths, vibration modes, and dispenser interfaces for a shape that existing dispensers weren't designed to hold. NASA's own environmental verification guidance, GSFC-STD-7000, assumes a modular spacecraft with separable levels of assembly. A flat satellite's integrated planar structure doesn't decompose that way, which forces structural and mechanical engineers to develop new analysis methods and test fixtures.

Thermal engineering gets harder, not easier. A CubeSat's compact volume gives thermal engineers a relatively predictable environment: heat conducts through a small number of well-characterized paths, and the surface-area-to-volume ratio is manageable. A flat satellite's extended geometry changes the thermal profile entirely. Heat dissipation across a thin plane creates gradients that don't exist in a cube. The NASA Small Spacecraft Technology State of the Art Report notes that miniaturized thermal control technologies (passive coatings, heat pipes, phase change materials) must be adapted for the high power densities and constrained volumes of small satellites. For DiskSat, the challenge is inverted: the volume is constrained in one dimension but extended in two, which means thermal engineers must model and test a heat flow regime that sits outside the standard CubeSat thermal handbook. Two-phase flow-based thermal control systems, including heat pipes and mechanically pumped loops, have been used on larger spacecraft but remain largely unexplored for small satellites, according to a review published in Acta Astronautica. DiskSat engineers are working in that gap.

Systems integration becomes the core discipline, not a phase. In a traditional CubeSat program, integration is a late-stage activity: you build boards, stack them in a chassis, close the box, and run a final set of environmental tests. NASA's CubeSat 101 guide describes a linear fabrication-and-test flow where the engineering test unit, FlatSat, and flight units serve distinct roles at distinct stages. DiskSat's form factor collapses that sequence. Because the satellite is flat, every component's placement affects structural rigidity, thermal coupling, and electromagnetic compatibility simultaneously. The ESA FlatSat project at ESTEC (a tabletop, opened-out CubeSat used for subsystem interoperability testing) illustrates the point: even for standard CubeSats, engineers have found value in testing all subsystems laid flat and accessible before integration. DiskSat essentially makes that flat configuration the flight article, which means the systems engineer must manage cross-domain interactions from day one, not at the end.

The talent profile that emerges is specific. DiskSat programs need engineers who can hold structural mechanics, thermal analysis, and electromagnetic self-compatibility in their heads at the same time. They need people who understand dispenser interface requirements well enough to argue for non-standard accommodations. They need test engineers who can design vibration and thermal vacuum campaigns for a form factor that doesn't match the protoflight assumptions in GSFC-HDBK-8007's Table 3. And they need manufacturing engineers comfortable with planar fabrication techniques that borrow as much from printed circuit board production as from traditional aerospace machining.

This is not a skill set that traditional satellite programs produce in volume. The CubeSat ecosystem has trained a generation of engineers to work within standardized constraints. DiskSat asks them to work outside those constraints while still meeting the same launch provider requirements, the same orbital debris mitigation rules, and the same reliability expectations — just in a shape the standards didn't anticipate.

Colorado Springs as the Quiet Hub

When the Pentagon announced in September 2025 that U.S. Space Command would relocate its headquarters from Colorado Springs to Huntsville, Alabama, the obvious story was loss. The less obvious one, the one that matters for anyone tracking where flat-satellite engineering talent is actually concentrating, is that almost nobody else is leaving.

The Aerospace Corporation opened its $100 million, 90,000-square-foot Space Warfighting Center at Peak Innovation Park near the Colorado Springs Airport in September 2022, a move that doubled its workforce in the state. The facility sits within reach of Peterson Space Force Base, Schriever Space Force Base, and Buckley Space Force Base, three installations that anchor the densest cluster of military space operations in the country. That co-location is not incidental. DiskSat's development depends on close integration with the Space Force's operational units, and Aerospace's Colorado Springs footprint puts its engineers in the same room, literally, as the people who will eventually fly the things they build.

The broader defense ecosystem in the city has followed a similar trajectory. Auria, a Colorado Springs-based defense contractor, announced in August 2023 that it would create more than 600 local jobs over eight years. After the Space Command relocation was confirmed, the company said the move would not significantly affect its operations and that it was continuing to hire on schedule. Infinity Systems Engineering announced its own expansion of nearly 500 roles in 2023, backed by $4.26 million in state tax credits tied to job creation. Mobius, a woman-owned small business specializing in space and missile defense, said it would add 75 workers at an average salary of $137,000 (roughly double the El Paso County average) days after the Space Command announcement. Nook, which provides classified workspace to the government, opened a 60,000-square-foot facility near the University of Colorado Colorado Springs and told The Colorado Gazette its commitment to the city was "unwavering."

The numbers on the ground back this up. Multiple senior technical leader positions based in Colorado Springs carry salaries between $155,900 and $233,900. LinkedIn shows 72 Aerospace Corporation jobs in the city. Indeed lists over 400 aerospace engineer openings and more than 530 aerospace engineering roles in Colorado Springs, a volume that reflects demand well beyond any single employer.

Governor Jared Polis said after the Space Command decision that Colorado's aerospace and defense industry would "only continue to grow stronger." The state's space economy, already the second-largest in the nation at $22.8 billion, has structural advantages that a headquarters relocation does not touch: the Space Force's operational presence remains concentrated in Colorado, the workforce pipeline fed by UCCS and the base-adjacent contractor ecosystem is deep, and the cost of living, while rising, still undercuts the Washington, D.C. corridor and Southern California.

For DiskSat specifically, Colorado Springs offers something Huntsville and Washington do not: a single metro area where the satellite designer, the integrator, the manufacturer, and the military end user all operate within a short drive of each other. That proximity compresses development cycles. It also means the engineers building flat satellites are not commuting between a corporate campus and a government office in different states; they are working the same problem in the same time zone, often on the same base.

The Space Command headquarters will move. The talent behind the spacecraft that matter most is staying put.

Government-Furnished Talent and the Workforce Pipeline

The Aerospace Corporation's government-furnished talent (GFT) program, announced in April 2026, is reshaping how flat-satellite expertise moves between the public and private sectors. The model is straightforward: Aerospace loans its own engineers and lab infrastructure to companies that need them, rather than forcing those firms to build domain knowledge from scratch.

CEO Tanya Pemberton framed the program as an extension of the government-furnished equipment (GFE) concept that defense contractors already know well. "In this case, we're trying to implement a way for the government to make the expertise, the lab capabilities, all of the domain experience that we have available to the private sector and especially to new entrants that might not yet understand some of the things that they need to worry about in space," Pemberton told SpaceNews.

The practical effect is significant. Aerospace operates a 30-foot vacuum chamber for electric propulsion testing, along with personnel who can interpret results from those tests. For a startup building its first flat satellite, buying that capability is unrealistic. Getting access to it through GFT is not.

The program works across clearance levels (unclassified, secret, top secret, and above) and Aerospace can operate under nondisclosure agreements, which matters when proprietary spacecraft designs are involved. "We know how to handle the data appropriately," Pemberton said.

What this means for the DiskSat workforce pipeline is direct. Companies working on flat-satellite programs can pull in Aerospace engineers who already understand the integration challenges of ultra-thin spacecraft form factors, without waiting months to recruit and clear those people independently. The bottleneck shifts from hiring to execution.

Aerospace's own hiring numbers reflect the demand behind this model. Zero G Talent's board shows 35 roles added at the company in the past seven days alone, including senior technical leaders in spectrum warfare and multi-domain sensing based in Colorado Springs. These are the same people the GFT program makes available to industry.

The program also feeds the pipeline in the other direction. Engineers who start at a commercial flat-satellite company and work alongside GFT-assigned Aerospace staff gain exposure to national security space standards and practices. That cross-pollination builds a workforce that can move between commercial DiskSat programs and classified government work, a dual-track career path that didn't exist at scale before.

Pemberton positioned Aerospace as occupying the space between government and the private sector, "leveraging and harnessing what the private sector is bringing to the table so that we can accelerate what the nation needs in space." For flat-satellite engineers, that middle ground is where the jobs are forming right now.

Who Else Is Chasing Flat-Satellite Talent

The Aerospace Corporation's DiskSat program isn't the only driver pulling demand for miniaturized spacecraft engineers. The talent pool is tightening across multiple employers simultaneously, though each is fishing from a different angle.

Northrop Grumman's job board shows 2,940 open positions, with 32 added in the past week alone. The roles most adjacent to flat-satellite work (Staff Integration Engineer, Principal/Sr. Principal DevOps Engineer, Embedded Software Engineer) cluster in the $131,700 to $241,400 range. The company's Colorado Springs and El Segundo locations overlap directly with the geography where The Aerospace Corporation is hiring. Northrop's scale gives it an advantage in volume, but its satellite work skews toward traditional large-bus programs like James Webb and military payloads. The company hasn't publicly signaled a DiskSat-style flat-satellite thrust, which means its demand for miniaturization talent is diffuse rather than concentrated.

Rocket Lab is a different story. The company added 44 roles in the past week, more than either Northrop or The Aerospace Corporation, and its Long Beach and Middle River locations are actively hiring Senior Digital Payload Engineers and Senior Systems Engineers with salaries reaching $190,000. Rocket Lab's small-satellite heritage through its Electron bus and Photon spacecraft platform means it's been competing for this exact talent category longer than most. The company's vertical integration model, where it builds both the rocket and the spacecraft in-house, creates demand for engineers who understand the full stack from payload to orbit — a profile that overlaps heavily with what DiskSat requires.

The salary data tells its own story. Here's how the three employers compare on recent postings most relevant to miniaturized spacecraft work:

Rocket Lab's lower salary floor reflects its mix of entry-level and mid-career postings, while The Aerospace Corporation's higher ceiling ($249,600 for a Sr. Sentinel Payloads Engineer) reflects its government-furnished talent model and the security-clearance premium baked into its compensation structure.

The real competition isn't just about headcount. It's about who can offer engineers the most interesting problem. DiskSat's form factor is genuinely novel — a thin disc that challenges every assumption about how a satellite is structured, powered, and thermally managed. Rocket Lab offers flight heritage and rapid iteration cycles. Northrop offers scale and mission assurance rigor. Each pulls a different slice of the same talent pool, and none of them are slowing down.

What Engineers and Operators Should Watch Next

The four DiskSats that launched in December 2025 are still beaming back data from low Earth orbit, and the early results already shape what comes next. All four spacecraft successfully communicated, generated substantial power, and controlled their orientation. Thruster demonstrations, formation flying tests, and low-altitude passes are feeding engineering refinements (particularly around thermal management and optical sensors) that will define the next hardware revision.

That flight heritage matters because it moves DiskSat from a paper trade study to a platform with real on-orbit credentials. Once operators prove the form factor can survive and perform, procurement conversations shift from "why try this" to "how fast can we get it." The Aerospace Corporation knows this. It is making DiskSat available for licensing on purpose-built documentation, and it is deliberately keeping partnerships non-exclusive to let multiple companies manufacture, develop payloads, and build constellation architectures around the disk shape.

Watch the low-altitude campaign closely. Aerospace has said it plans to demonstrate operations below 350 kilometers in spring 2026. If DiskSat can sustain useful payload performance at 200 kilometers using electric propulsion to fight drag, that opens a regime where traditional boxy small satellites cannot operate cost-effectively. Sharper Earth observation imagery and better communications link budgets at that altitude would turn the form factor into a mission enabler rather than a novelty.

For engineers mapping career moves, the signals are concrete. The Aerospace Corporation added 35 roles in the past week on Zero G Talent's board, including senior technical leads in Colorado Springs and payload engineers at Hill Air Force Base. Boeing and Millennium Space Systems announced Resolute, a mid-class satellite platform that signals the primes are scaling production and broadening their portfolios to meet demand for flexible, faster-delivery spacecraft. Rocket Lab posted 44 roles in the same window, including senior digital payload engineers in Long Beach. The hiring is not speculative — it is tied to funded platforms and production backlogs.

The broader market context supports the trend. NASA's own state-of-the-art report noted that DiskSat's circular configuration and larger surface area "will challenge the way SmallSat's are perceived." The agency's VADR launch services contract mechanism now covers missions from simple CubeSats through complex Class D payloads, meaning more rideshare and dedicated launch options for unconventional form factors. Flat panel antenna markets are projected to grow at double-digit compound annual rates through the 2030s, driven by phased array technology and demand for high-speed satellite communications, a demand signal that pairs directly with DiskSat's large-aperture advantage.

The next 18 months will determine whether DiskSat becomes a standard platform or remains a government demonstration. Engineers who can design for the flat form factor (power systems that exploit the large surface area, antennas that use the aperture, thermal solutions for the unique cross-section, and integration and test processes that exploit the simplified flat layout) will be positioned for whatever scale-up follows. Monitor Aerospace's published flight results, watch for the first commercial or Defense Department procurement that references the disk form factor, and track whether the licensing pipeline produces partner-built spacecraft. Those three signals will tell you whether this hiring surge is the start of a structural shift or a short-cycle spike.
