How does the word astronauts function in the sentence nasa gave the astronauts a course correction?

Indirect object

Explanation:

 In the sentence Nasa gave the astronauts a course correction,  the word astronaut has the function of an indirect object  of the verb gave, which has two complements: direct and indirect objects. The direct object is a course correction,  that, in this case, comes after  the indirect object. This is equivalent to writing Nasa gave a course correction to the astronauts.

i think the answer would mist likely be an adjective clause, because unhappy is an adjective.
