How to Apply
Application Timeline
The single biggest reason students miss aerospace internships is timing. Most start looking in spring for summer positions — by which point the best programs are already closed. Here's the real timeline:
| When | What Happens | Your Action |
|---|---|---|
| August | Boeing, early prime postings open | Create accounts on all career portals. Polish resume. Start applying. |
| Sep–Oct | SpaceX, Blue Origin, Anduril post. AFRL Wright Scholar opens Oct 10. Boeing Engineering deadline. | Apply to rolling programs immediately. Submit Boeing before it closes. |
| Nov–Dec | Lockheed Martin HS opens/closes. RTX, Northrop accumulate. | Apply to LM HS. Broad college applications. |
| January | AFRL programs close. NASA OSTEM prep. | Submit AFRL. Prepare NASA applications. |
| February | NASA OSTEM, Pathways, SEES, FAA Gateways close. | Submit all federal applications. Apply to REUs. |
| March | NSF REU deadlines. Last rolling positions fill. | Final applications. Follow up. Plan for next year if needed. |
Set calendar reminders now. If you're reading this outside of application season, open your calendar and add reminders for August 1 ("start aerospace internship applications"), October 10 ("AFRL Wright Scholar opens"), and January 1 ("prepare NASA/FAA applications"). Your future self will thank you.
Building Your Application List
If any individual program has a 5–10% acceptance rate, you need to apply to 15–20 programs to have a reasonable chance of landing one. Here's how to build your list:
The "Apply to 20" Strategy
- 3–4 government programs: NASA OSTEM, AFRL (Wright Scholar or Scholars), FAA Gateways, and one more based on your interests.
- 3–4 prime contractors: Boeing, Lockheed Martin, Northrop Grumman, RTX, L3Harris, or GD. Apply to multiple — they're different companies with different cultures.
- 3–4 startups/NewSpace: SpaceX, Blue Origin, Anduril, Shield AI, Skydio. Rolling deadlines make these accessible year-round.
- 2–3 eVTOL or emerging: Joby, Archer, or other companies in our eVTOL guide. Especially valuable if citizenship restrictions limit your options.
- 5+ NSF REU sites: Apply to at least 5–10 research sites if you're considering graduate school.
Diversify across categories. Don't put all your applications into one category. Government, primes, startups, and REUs have different selection criteria, different timelines, and different acceptance rates. Spreading your bets maximizes your odds.
What Hiring Managers Look For
What matters, in order of importance:
- GPA and relevant coursework. 3.0+ is the floor for most programs. 3.5+ opens more doors. But coursework matters as much as the number — an aerospace-relevant course load (structures, thermo, fluids, controls) signals preparation.
- Technical projects. TARC rockets, FIRST robots, personal CAD designs, coding projects, 3D-printed wings, Arduino flight controllers. These prove you can build things — not just study them.
- Relevant skills. MATLAB, Python, SolidWorks/Fusion 360, any lab or machining experience. List specific tools, not vague "proficiencies."
- Competition results. TARC, FIRST, Science Olympiad, StellarXplorers, AIAA DBF, Spaceport America Cup. Hiring managers in aerospace know these competitions by name.
- Clubs and organizations. AIAA student chapter, rocketry club, robotics team, SAE Aero Design. Active membership (especially leadership) signals initiative.
- Work experience. Even non-aerospace jobs show reliability, work ethic, and the ability to function in a professional environment.
What doesn't matter as much as you think: The prestige of your school (NASA interns come from community colleges and HBCUs, not just MIT). Your exact major (mechanical engineering is fine for most aerospace roles). Fancy formatting on your resume.
Open vs Closed Programs
Understanding the difference between fixed-deadline and rolling-admission programs changes your entire application strategy:
Fixed Deadline Programs
All applications are reviewed together after the deadline passes. Missing the deadline means waiting until next year.
- NASA OSTEM, Pathways, GL4HS, SEES
- AFRL Wright Scholar, AFRL Scholars
- FAA Gateways
- Boeing Engineering (closes early — October)
- Lockheed Martin HS program
Rolling Admission Programs
Applications are reviewed as they arrive. No single deadline, but positions fill up. Earlier is always better.
- SpaceX, Blue Origin, Anduril, Shield AI, Skydio
- Northrop Grumman, L3Harris, RTX (college)
- Joby Aviation, Archer Aviation
The strategy: Submit fixed-deadline applications well before the deadline — don't wait until the last day. For rolling programs, apply as early as possible — the best roles go first. Never assume a "rolling" deadline means you can wait until spring.
Common Mistakes
Avoid these mistakes that cost students internships:
- Starting too late. The #1 mistake. Students who start looking in March have already missed NASA, AFRL, Boeing Engineering, and Lockheed Martin HS. Start in August.
- Applying to too few programs. If acceptance rates are 5–10%, applying to 3 programs gives you roughly a 15–27% chance of getting zero offers. Apply to 15–20.
- Generic applications. "I'm passionate about aerospace" means nothing. Reference specific missions, programs, products, or research areas. "I want to work on Artemis thermal protection systems at Marshall Space Flight Center" is a real statement.
- Using AI to write your NASA application. NASA explicitly prohibits this and will disqualify applicants. Write your own words.
- Ignoring citizenship requirements. If a program requires US citizenship and you're a permanent resident, don't apply — you'll waste your time. Focus on programs that accept your status (NASA OSTEM, NSF REU, eVTOL companies).
- Only applying to "dream" programs. SpaceX and NASA are the most competitive internships in aerospace. Apply to them, but also apply to Northrop Grumman, L3Harris, RTX, and REU sites where your odds are better.
- No technical projects on your resume. An empty projects section is the biggest gap. Start a rocketry project, build something in CAD, write a simulation in MATLAB — do it now so you have something to show.
- Not attending career fairs. Prime contractors recruit heavily at university career fairs. Showing up, making a good impression, and handing over a resume is still one of the most effective ways to get an internship.
