How Are Space Probes to the Outer Planets Such as Jupiter

question 129

Multiple Choice

How are space probes to the outer planets such as Jupiter protected from being obliterated by collisions with asteroids in the asteroid belt?

• A) They aren''t. We lose only one out of every four spacecraft to collisions with asteroids, so it is cheaper to take our chances.
• B) The spacecraft are equipped with cameras to detect asteroids so that they can be directed safely around them.
• C) The spacecraft are sent in an inclined orbit that arcs above or below the asteroid belt, then crosses the ecliptic again near Jupiter.
• D) They aren''t. Asteroids are so far apart that the spacecraft just sail through.

Definitions:

Saddle

A type of synovial joint that allows movements in several axes, found in areas such as the thumb base, characterized by fitting together like a rider and a saddle.

Hinge

A joint or mechanism that allows parts to pivot or swing around a fixed point, often found in doors or lids.

Pivot

Pivot refers to a central point, pin, or shaft on which a mechanism turns or oscillates, enabling movement or rotation around a single axis.

Synovial Fluid

A lubricating fluid produced by the synovial membrane in joint cavities, aiding in smooth joint movements by reducing friction.
