Easy

Which country launched the first artificial satellite, in 1957?

Source: The USSR shocked the world with the launch, kicking off the Space Race.

Question 2

Easy

What was the name of that first satellite launched in 1957?

Source: Sputnik means 'travelling companion' in Russian, and it just went beep-beep on radio.

Question 3

Easy

What force keeps a satellite circling the Earth instead of flying off?

Source: A satellite is actually falling toward Earth forever, but moving sideways fast enough to miss.

Question 4

Easy

Which satellite system lets your phone show where you are?

Source: GPS was built by the US military before being opened up for everyday navigation.

Question 5

Easy

Which satellite network does SpaceX use to beam internet from orbit?

Source: Starlink already has thousands of satellites, making it the largest constellation ever built.

Question 6

Easy

Dead satellites and broken fragments left orbiting Earth are called what?

Source: There are millions of debris pieces zipping around, some travelling faster than a bullet.

Question 7

Easy

Meteorologists rely on satellites mainly to track what?

Source: Weather satellites let forecasters spot hurricanes days before they reach land.

Question 8

Easy

The Moon is best described as Earth's what?

Source: Any object orbiting a planet is a satellite, so the Moon is simply a natural one.

Question 9

Easy

What happens to most low-orbit satellites at the end of their lives?

Source: Friction with the thin upper air drags them down until they vaporise like shooting stars.

Question 10

Easy

Satellite phones are most useful in areas without what?

Source: They talk straight to orbit, so they work mid-ocean or deep in the desert.

Question 11

Medium

Geostationary satellites orbit at roughly what altitude above Earth?

Source: At that height they circle once a day, appearing to hang motionless over one spot.

Question 12

Medium

What animal was the first living creature to orbit Earth, aboard Sputnik 2?

Source: Laika the dog flew in 1957, years before any human reached orbit.

Question 13

Medium

Geostationary satellites all sit directly above which line?

Source: Only above the Equator can a satellite hover over one fixed point on the ground.

Question 14

Medium

How many satellites must a receiver lock onto to fix your exact position?

Source: Three give location and a fourth corrects the clock, since light-speed timing must be perfect.

Question 15

Medium

Which famous telescope is itself a satellite orbiting the Earth?

Source: Hubble orbits above the blurry atmosphere, which is why its images are so sharp.

Question 16

Medium

Today, the vast majority of active satellites sit in which orbit?

Source: Cheaper launches and mega-constellations have packed low orbit with thousands of craft.

Question 17

Medium

Satellites that scan the entire planet usually fly in which orbit?

Source: Crossing the poles lets the Earth rotate underneath, so the satellite eventually sees everything.

Question 18

Hard

Which science-fiction author popularized the idea of communication satellites?

Source: Clarke described geostationary relay satellites in 1945, two decades before any existed.

Question 19

Hard

About how fast does a satellite in low orbit actually travel?

Source: That blistering speed lets a low satellite circle the whole planet in about 90 minutes.

Question 20

Hard

Roughly how many active satellites are orbiting Earth right now?

Source: The number has exploded in recent years, with one company owning over half of them.
