- Question 3:
- Why were the Hubble Space Telescope and other space telescopes involved in the Deep Impact mission?
The Hubble Space Telescope and other space telescopes watched (and took images of) the collision between the comet and the impactor. This was an once-in-a-lifetime event.
Each space telescope observed the event in a different part of the electromagnetic spectrum to capture as much of the action as possible. What is visible in one portion of the spectrum may not be visible in another. For example, the Hubble Space Telescope collected visible light, the Spitzer Space Telescope gathered information in infrared light, and Chandra looked for X-rays coming from the comet.
