While conducting research on space exploration, a student took the following notes:
* Voyager 1 is a space probe launched by NASA.
* It was launched on September 5, 1977.
* Its primary mission was to study the outer Solar System.
* It entered interstellar space in August 2012.

The student wants to write a sentence that emphasizes the date of Voyager 1's launch while also mentioning its primary mission. Complete the sentence by filling in the blank with the appropriate detail from the notes.

Answer:Originally launched on 【September 5, 1977】 to study the outer Solar System, the Voyager 1 space probe eventually entered interstellar space in August 2012.

Answer

September 5, 1977
The correct answer is the launch date, September 5, 1977, because the sentence structure already includes the primary mission ('to study the outer Solar System') and requires the launch date to complete the introductory modifier emphasizing when it was launched.
