No spacecraft has been built yet that was able to absorb harmful 
radiations in space, change weather conditions on Earth, or destroy 
meteors and comets which might strike Earth.
We should continue to send robotic spacecrafts into space 
because they help discard some myths about objects in space.  
In other words, they help us learn things that we never knew before.
        
             
        
        
        
Answer:
230 m/s northeast, 1.8 m/s up
Explanation:
204 kilometres = 204000 metres
15.0 minutes = 900 seconds
Velocity = Distance / Time
= 204000 / 900
= 230 m/s northeast (to 2 sf.)
1.6km = 1600 metres
Velocity = 1600 / 900
= 1.8 m/s up (to 2 sf.)
