50 free SpaceX trivia questions with answers — science & nature quiz, new questions added Aug 2026.
SpaceX was three failed launches from bankruptcy in 2008. A fourth Falcon 1 reached orbit from a Pacific atoll, NASA signed a $1.6 billion cargo contract that December, and the company went on to land orbital boosters on barges, fly astronauts from Florida again, put a Tesla Roadster into orbit around the Sun and build the largest rocket ever flown in a Texas field. These 50 questions cover the whole story: the Mars Oasis idea and the trips to Moscow, Omelek Island, the Merlin and Kestrel engines, the first drone-ship landing on Of Course I Still Love You, the CRS-7 strut and the AMOS-6 fireball, Demo-2's Endeavour, Inspiration4 and the first private spacewalk on Polaris Dawn, Starlink's 60-satellite batches, Starship's stainless steel and tower catches, Gwynne Shotwell and the 2026 IPO. The expert tier asks about RazakSAT, the Culture novels behind the drone-ship names, the 5D disc in Starman's glovebox and the worm logo. Every answer is cited to a page we checked and comes with a short explanation, so you learn something even when you miss. Play solo or print it for a space night.

Malaysia
RazakSAT rode the fifth and last Falcon 1 in July 2009 before the rocket was retired.
Q 06Which NASA contract, worth $1.6 billion in December 2008, is credited with saving SpaceX?
Commercial Resupply Services
It bought 12 cargo flights to the ISS; Gwynne Shotwell was made president for negotiating it.
Q 07What did Musk's 2001 'Oasis' space project propose to do?
Land a greenhouse on Mars

Q 09How many Merlin engines power the first stage of a Falcon 9?
Nine
The upper stage uses a single vacuum-optimised Merlin; Falcon Heavy's three cores carry 27.
Q 10What propellants does the Merlin engine burn?
Liquid oxygen and RP-1
RP-1 is a refined kerosene; the Starship-era Raptor switched to methane.
Q 11Which engine powered Falcon 1's second stage?
Kestrel
It was a pressure-fed engine using the same LOX/RP-1 propellants as Merlin.
Q 12What are the small thrusters used for the capsule's reaction control called?
Draco
Eight larger SuperDracos give Crew Dragon its launch-escape capability.
Q 13What fuel does the Raptor engine burn alongside its oxidiser?
Liquid methane
Raptor is a full-flow staged combustion engine first flown in 2019 on the Starhopper test vehicle.
Q 14In which year did a Falcon 9 first stage first land successfully after an orbital launch?
Q 21What is the mannequin in the driver's seat of the space-bound Roadster called?
Starman
He is named after a David Bowie song, and the car's stereo was set to loop 'Space Oddity'.
Q 22A copy of which novel sits in the Roadster's glovebox, with a 'DON'T PANIC!' sign on the dash?
