6.11 BC Gravity / Space exploration check for understanding

The Sun is the center of our solar system and creates a large amount of gravitational force.

If this system lost the Sun, what would happen to the planets?

• The planets would explode.

• The planets would stop moving.

• The planets would travel on a different path.

• The planets would continue on their same path.

Which statement typically demonstrates the relationship between the mass of a celestial

body and its gravitational pull?

• Mercury has the least mass of the planets in the solar system, so it has the greatest

  gravitational pull.

• Venus has less mass than Earth, so Earth has a lesser gravitational pull.

• Jupiter has the greatest mass of the planets in the solar system, so it has the greatest

  gravitational pull.

• The mass of a celestial body is not related to its gravitational pull on other bodies.

Over time, NASA has developed many different vehicles to carry men and women into space. These craft have changed to allow longer stays in space, carry more astronauts, and conduct more investigations. Until recently, the U.S. has used the space shuttle.

The space shuttle differed from previous space vehicles because it —

• was reusable

• could carry more than one person

• could travel beyond Earth's orbit

• was airtight

In space travel, a probe is a vehicle designed to carry instruments, but not crew. To which of

the following places would we most likely send a probe?

• The International Space Station

• Inside the Sun

• Mountain top

• Saturn
