The Space Force Is About to Launch a Mysterious Spacecraft

I am a tad confused about this one because it says this was the first and then further down said it was the second.

I understand the first one was to see how seeds behaved in space re radiation affects.

Looking at it shows two people in space suites heading to the plane for this one about to be launched.

Just read it again (made a bit more sense) haven't had my first coffee yet.

There is more to read at the bottom if you want more info. hat
