Dear native English speakers,
I have a little question about the use of "at" here.
Traveling faster than the speed of sound, the rocket reached a height of 3,500 meters in just 25 seconds. It is now used for experiments at research institutes such as JAXA.
What does this "at" mean? Can it be replaced with another preposition "in" or "by"?
