Space Systems & Satellite Engineering Certification

The Space Systems & Satellite Engineering Certification is a free advanced-level, 25-minute skill test from Science of Apps. It tests space systems and satellite engineering — orbital mechanics and Kepler's laws, orbit types from LEO to GEO and sun-synchronous, delta-v, the rocket equation and Hohmann transfers, launch vehicles and rideshare, spacecraft subsystems for structure, power, thermal, propulsion, attitude determination and control, command and data handling and communications, link budgets, modulation and CCSDS standards, ground segment and TT&C, the space environment including radiation, atomic oxygen and debris, reliability, redundancy and radiation-hardened parts, systems engineering with requirements, margins and technology readiness levels, assembly, integration and test including vibration and thermal vacuum, mission operations, constellations and smallsats, space law from the Outer Space Treaty to spectrum coordination, and debris mitigation and end-of-life disposal — written to NASA, ESA, ECSS, CCSDS, ITU, FCC and IADC sources for 2026 and 2027. Score 70% or more on its 25 questions to earn a verifiable Space Systems & Satellite Engineering certificate (SOA-SSSE). Every question is based on published standards and research — including NASA Systems Engineering Handbook (NASA), Basics of Space Flight (NASA Jet Propulsion Laboratory), ESA space engineering, missions and education resources (European Space Agency) — and each answer is explained with its source.

Science of Apps offers a free Space Systems & Satellite Engineering Certification, written for 2026 and 2027. It tests orbital mechanics, launch and spacecraft subsystems, communications and ground segment, environment, reliability and engineering and missions, law and sustainability with 25 original scenario questions in all, each naming its published source; you get an instant score and a verifiable certificate with a credential ID you can add to LinkedIn.

Read the five skill areas on this page, then take the 25-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Space Systems & Satellite Engineering certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: NASA Systems Engineering Handbook (NASA); Basics of Space Flight (NASA Jet Propulsion Laboratory); ESA space engineering, missions and education resources (European Space Agency); CCSDS space data system standards (Consultative Committee for Space Data Systems); IADC Space Debris Mitigation Guidelines (Inter-Agency Space Debris Coordination Committee); European Cooperation for Space Standardization standards (ECSS). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Orbital Mechanics (Kepler and orbits, Orbit types and Manoeuvres); Launch and Spacecraft Subsystems (Launch, Power and thermal and Propulsion and ADCS); Communications and Ground Segment (Link budgets, Protocols and Operations); Environment, Reliability and Engineering (Space environment, Reliability and Systems engineering and AIT); Missions, Law and Sustainability (Constellations and smallsats, Space law and Debris and disposal). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Aerospace or systems engineer, Satellite operator or mission analyst, Space startup engineer or founder, Defence or civil space programme manager and Graduate student in astronautics. It suits students at leading universities, career switchers and experienced professionals who want quick, verifiable proof of Space Systems & Satellite Engineering knowledge in 2026 and 2027.

Engineering cohorts at IITs, KAIST, NTU Taiwan, TUM, Tsinghua and Georgia Tech are being pulled into chips, energy and space. Passing earns a founder-signed Science of Apps certificate with a credential ID and QR code that recruiters can verify.

A sun-synchronous orbit precesses about one degree per day so that the satellite crosses a given latitude at roughly the same local solar time, giving consistent lighting for imagery comparison.

The change in velocity a manoeuvre requires; it is the standard currency of mission design because the rocket equation links delta-v to the propellant mass fraction and the engine's exhaust velocity.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

25 questions — 5 from each of 5 skill areas — with a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

We rate it Advanced: assumes years in the role or deep specialist knowledge. It has 25 scenario questions — 5 from each of 5 skill areas — and a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
