since nasa began leading and continues to do so in the present hence the usage of present perfect tense.
Hope it helps.

Hi krisjoan,

The presence of the word "Since" at the beginning of the sentence indicates that the action started in the past and is still continuing in the present which mandates the usage of the present perfect.

I hope it is more clear now


Please press kudos if it was helpful
