Question

when scientists viewed the first images from the hubble space telescope, they were discouraged. the images were not nearly as clear as expected. in december 1993, more than two and a half years after the launch of the hubble space telescope, nasa launched its most ambitious space mission since astronauts landed on the moon. the space shuttle endeavor went into orbit with a crew of seven to completely overhaul the telescope and repair the malfunctioning instruments. initially, the hubble space telescope was ______?

• taboo
• unsatisfactory
• prestigious
• expandable

Explanation:

The text states scientists were discouraged by Hubble's first images, which were not as expected, and a later overhaul was needed to fix malfunctioning instruments. This shows the initial state of the telescope was not up to standard. "Unsatisfactory" means not meeting expectations, which matches the context. The other options do not fit: "taboo" refers to forbidden things, "prestigious" means respected/renowned, and "expandable" means able to be enlarged.

Answer:

unsatisfactory
