Make sure your response is 3-5 sentences. What are some of the extreme conditions in space that challenge manned space exploration?

please see below

Explanation:

A manned space exploration is defined as the exploration of individuals --- astronauts in space using a spacecraft as a vehicle and are  responsible for operating its controls

The extreme conditions in space that challenge manned space exploration is as follows.

1. extreme loud sound waves cause by the launch of spacecraft which can shatter the spacecraft

2. extreme Temperatures in space ranging from extreme hot temperatures  (near the sun) to extreme cold temperatures  ( below freezing point out of space.

3.micrometeorite showers responsible for sandblasting can  damage spacecraft.

4.Ultra violet Radiation which can alter the control unit of the spacecraft  

Because of theses extreme conditions that pose challenges to space explorations, necessary precautions should be taken into consideration to be able to overcome such challenges. These precautions include building the spacecraft and the control unit in such a way that can resist these harmful conditions, also taking in mind safe escape routes for the astronauts in case of failures.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
