The first instrument used to explore space

• satellites

• radio telescope

• rockets

• optical telescope

What are satellites mostly used for?

• radio

• television

• GPS

• all of these

Rocket engines are better adapted for space because

• the do not use fuel

• they have GPS

• they do not need air

• they have better communication technology

A space probe is different from a satellite because the probe can:

• travel far into the solar system

• orbit the Earth

• transport astronauts

• be reused

What can receive radio wave emitted from objects in space, including waves from distant stars?

• reflecting telescopes

• radio telescopes

• the Hubble space telescope

• infrared telescopes

NGSS.MS-ETS1-2

A refracting telescope uses:

• mirrors

• lenses

• radio waves

• lasers

These natural objects in space can orbit the sun:

• comets and meteors

• asteroids and comets

• asteroids and meteoroids

• meteoroids and comets

NGSS.MS-ESS1-2

These are sometimes referred to as "minor" planets

• asteroids

• meteoroids

• comets

• meteorites

Meteors that are close enough to see are called

• asteroids

• comets

• shooting stars

• meteoroids
