In his early career:
No telescopes.
A log to track planets.
Sea-faring devices such as the sextant
Later in life:
In 1609 Galileo started using the telescope on the 'heavens'
Kepler used the Galilean telescope until 1611 he re-invented the refracting telescope (now known as the Keplerian telescope)
he did not use telescope because it was not invented yet

other space units that can shoot off of Earth by rocket

they use space probes,satellites,and of coarse,telescopes.
Space junk gets into space by astronauts dropping there gloves or a tool when they are working at a space station, or things that come off a space station. in other words the only space junk there is, is from us humans.

All you have to know is who Galileo Galilei is. He is a man from thousands of years ago who studied space. I really don't know. I'm in 5 grade and this is what we are learning. Well, yo momma will tell ya
My dear friends its the telescope! That was the first instrument (tool) to use to study space and astronomy. For your information.. ( FYI) Galileo was the first man to invent and use the telescope. By the way I'm in the 5th grade but we learn a lot of good astronomy stuff in class. I'm pretty smart
light speed:)
microscope
some tools in space are RADAR, is a system for locating unseen objects the reflections of frequency radio waves. Another tool for space is the hubble space telescope (HST). Another space tool is a space suit so you can breate oxygen if you are outside the space shuttle.
A tool is something that helps you build or unbuild things.
It was used to remove penises from the male body.
