Day in the Life

Hrs / week~55engineering officetest facilityclean roomlaunch site
My alarm goes off at 6:15 AM and I check Slack before I'm out of bed — there was a late-night hot fire test on the Raptor engine at SpaceX and the data just came in. I'm at my desk by 8 AM reviewing telemetry: chamber pressure, mixture ratio, turbopump speeds. Something looks slightly off in the regenerative cooling data and I flag it in the team channel immediately. By 9 AM I'm in a stand-up with twelve engineers — propulsion, structures, avionics — everyone ten seconds flat on what they're doing today. Then I'm deep in MATLAB for two hours, running a propellant performance analysis to see if a hardware tweak we made last week actually improved Isp (specific impulse — the fuel efficiency number we live and die by). Lunch is twenty minutes at my desk. The afternoon is a design review for a new injector plate: I'm presenting stress analysis results, and the senior engineer asks me a question I don't have the answer to on the spot. I write it down and get back to them by end of day — that's the culture here, you never bluff. Around 4 PM I get a Slack from a colleague on the GNC team: they need trajectory simulation data for a Starship test. I have it, I send it, and we talk for twenty minutes about a guidance algorithm tweak. I leave at 7 PM, tired but genuinely excited about what we're building. There's nothing else like this.

📍 Location: The aerospace industry is geographically concentrated: Los Angeles (SpaceX HQ, Northrop, Raytheon), Houston (NASA JSC), Huntsville AL (NASA Marshall, Boeing), Seattle (Blue Origin), and the DC corridor (defense contractors). SpaceX and Blue Origin pay competitively and are RSU/equity heavy, especially at senior levels — total comp can significantly exceed base. Traditional defense contractors (Lockheed, Northrop) pay more in base salary but have less equity upside and slower compensation growth. Government civil servant roles (NASA engineer, Air Force) pay 20-30% below industry but offer exceptional stability, clearance, and retirement benefits.

Top Programs

Massachusetts Institute of Technology (MIT)

BS

BS / MS Aerospace Engineering

Consistently #1 or #2 in aerospace engineering. Unmatched research access — if you want to work on spacecraft at the frontier, MIT AeroAstro puts you closest to it. Extraordinarily competitive admissions but equally extraordinary outcomes.

California Institute of Technology (Caltech)

BS

BS Aerospace Engineering

Tiny, elite, deeply rigorous. Located next to JPL (NASA's Jet Propulsion Laboratory) — many students work there. Best if you love the deep physics side of aerospace. Very hard to get in.

Georgia Institute of Technology

BS

BS Aerospace Engineering

Top-3 aerospace program with enormous industry connections. Strong in propulsion, structures, and systems. More accessible than MIT/Caltech and produces a very high volume of working aerospace engineers.

Purdue University

BS

BS Aerospace Engineering

Legendary aerospace reputation — more NASA astronauts than any other university. Strong industry recruiting pipeline to Boeing, Raytheon, GE Aerospace, and NASA. Excellent value.

University of Michigan

BS

BS Aerospace Engineering

Top-5 program with strong ties to the Detroit aerospace and automotive ecosystem, plus national lab connections. Broad curriculum covering both commercial and defense aerospace.

Advanced degree: Helpful but not required

An MS is useful for research-heavy roles (NASA centers, DARPA programs, national labs) and can accelerate promotion timelines in technical tracks. A PhD is genuinely rare in industry — most aerospace engineers don't need one and many PhDs find industry less satisfying after academia. The honest advice: go get a BS, get an industry internship at a place you'd actually want to work, and decide after that whether graduate school adds value for your specific goals. At SpaceX and most commercial space companies, hands-on experience and demonstrated competence matter more than graduate credentials.

School to Career

The stuff you're learning right now directly applies to this career — often in ways your teacher hasn't mentioned.

Courses That Matter

AP

AP Physics C: Mechanics & Electricity and Magnetism

Foundational

AP Physics C is the single most important high school course for an aspiring aerospace engineer. Newton's laws, rotational dynamics, work-energy theorem, electromagnetism — these aren't just physics concepts, they are the literal foundation of everything you'll do in orbital mechanics, propulsion, and structural analysis. Take both exams (Mechanics and E&M), take them seriously, and understand the calculus that drives them — don't just memorize formulas.

AP

AP Calculus BC

Foundational

Every important equation in aerospace engineering — the rocket equation, the Navier-Stokes equations, Newton's laws in three dimensions — requires calculus to write and understand. AP Calculus BC gets you through derivatives, integrals, and series. In college you'll extend this to multivariable calculus, differential equations, and vector calculus. But it all starts here, and aerospace majors who arrive with BC already solid have a real head start.

AP

AP Chemistry

Core

Rocket propellants are chemistry. Understanding combustion, chemical energy release, stoichiometry, and reaction products is directly relevant to propulsion engineering. Even if you specialize in structures or GNC, you'll work alongside propulsion engineers and need to speak their language. AP Chemistry builds that foundation.

AP

AP Computer Science A

Important

Modern aerospace engineering is computational. You'll write analysis scripts in Python, build simulations in MATLAB, and potentially write flight software in C++. Even if you never write production flight code, being comfortable with programming makes every analysis task faster and more powerful. CS A gives you the logic and coding fundamentals that you'll build on in every engineering course.

STANDARD

Physics

Foundational

If AP Physics C isn't available at your school, take whatever physics is offered and go as deep as possible. Every aerospace concept traces back to classical mechanics, thermodynamics, and electromagnetism. Physics is not a subject you can skip and backfill later — it builds cumulatively.

STANDARD

Calculus

Foundational

Even standard calculus — derivatives and integrals — gives you the mathematical language engineers use daily. Get through calculus as early as possible and push toward pre-calculus and calculus in middle and early high school if you can.

STANDARD

Chemistry

Core

Standard chemistry covers the atomic structure, periodic trends, and reaction chemistry that underpin propellant selection, materials compatibility, and corrosion — all real aerospace engineering concerns.

Extracurriculars That Count

🎯

FIRST Robotics Competition (FRC)

FIRST Robotics is the closest thing in high school to real aerospace engineering: you're on a team, designing a system under schedule pressure, iterating rapidly, and building something that has to actually work under competition conditions. The mechatronics skills (mechanical design, motors, sensors, programming) map directly to aerospace, and top aerospace employers actively recruit from FIRST alumni.

🎯

Model Rocketry (NAR / Tripoli)

There is no better way to fall in love with aerospace than to build, certify, and launch your own rockets. NAR (National Association of Rocketry) and Tripoli offer high-power rocketry certifications starting at Level 1 that let you fly rockets reaching thousands of feet. You'll learn about propellant selection, center-of-pressure vs. center-of-gravity stability, recovery systems, and motor specifications — real aerospace engineering, at a scale you can actually do in high school.

🎯

Science Olympiad

Science Olympiad events like 'Rocketry,' 'Wright Stuff,' and 'Air Trajectory' are directly aerospace-relevant and extremely competitive. The community skews hard toward STEM careers and the analytical rigor the competition develops is excellent preparation for engineering coursework.

🎯

AIAA Student Branch (if available at a nearby university)

The American Institute of Aeronautics and Astronautics (AIAA) runs design competitions (like the Design/Build/Fly aircraft competition) and student chapters at many universities. If there's a chapter at a nearby college, reaching out to join their activities or attend their events as a high schooler is an excellent signal of genuine interest and builds real connections.

If you've built model rockets and already know what Tsiolkovsky's rocket equation means, or if you can't stop asking why rocket engines don't melt, this is the career for you.

Who Got Here Before You

GS

Gwynne Shotwell

President & COO of SpaceX

Gwynne studied mechanical engineering at Northwestern, became a propulsion engineer, and rose to run SpaceX operations as President and COO — she's the person who actually makes SpaceX's business run day to day. She has said in interviews that she loved math and physics in school and became an engineer because a female mechanical engineer spoke at her school when she was a teenager. Direct proof that one talk can change a career path.

SW

Sunita Williams

NASA Astronaut, Engineering Test Pilot, Commander of the ISS

Sunita Williams has a BS in Physical Science from the Naval Academy and an MS in Engineering Management from Florida Institute of Technology. She's a test pilot and engineer who has spent over 300 days in space, including long-duration missions on the International Space Station. In 2024 she was launched on Boeing's Starliner crew flight test — a mission that became unexpectedly extended, and she handled it with extraordinary professionalism. She represents the full arc of aerospace: engineering, flight test, operations, and leadership.

KB

Kofi Boateng

Rocket Propulsion Engineer, YouTuber / Content Creator

Kofi is a working rocket propulsion engineer who documents his career on YouTube and social media in a way that's genuinely accessible and honest — he talks about what the day-to-day actually looks like, how he got there, and what being a Black engineer in aerospace means. He's one of the most effective communicators translating aerospace engineering to a general audience, and he makes the career feel real and achievable rather than remote and intimidating.
