Scientists do research, do test and go into a space vehicle to do experiments. They also go out the space vehicle in space suits.
scientists use spacecraft without people to explore space because scientists need to know more about space and the solar system
So they can explore space
They are trained NASA scientists who explore space.
By using robot space probes and telescopes
To explore and look at other planets and further
light telescopes and radio telescopes whether installed on earth or on space vehicles
Telescopes, Space missions, probes all help scientists discover more about the moon.
which layers of the earth have scientists been able to explore
Space probes explore space for a quite obvious reason; they are SPACE probes. They probe space.
Space
Because of the vastness of outer space and the difficulties it poses for survival, scientists generally can't conduct laboratory experiments to explore it. Instead, they must depend on upon their observations.
space stations use a variety of objects to explore space. probes and the Hubble Space Telescope are main ones.
