(Havenāt watched the movie, this is based on the book)
Stratt sends a Beetle back to find Grace named L.I.B, having it lock onto the original Taumoaba, she sends twoā one crashes into Adrian but one makes it to Grace on Erid.
Inside are four USB sticks, and one camera. The first holds a note from Stratt to Grace, telling him how Earth is now, whatās changed for the better since the return of the Beetles, whatās changed for the worse. She kept tabs on the students in his class, telling him how they grew up, who they became. Abby became a scientist. A handful became teachers.
She explains that the camera is empty, for Grace to use and send back to them, one of the USB sticks has photos from Earth. The other has digital letters from his students as they grew, and learned about his sacrifice.
The last USB stick has a collection of every piece of media and intellectual property made from when he left up until now.
In the end of the letter she says;
āDonāt just send me a picture of you giving me the middle finger, I wonāt be alive to see it.ā
22 months later, Earth gets a bunch of pictures of fucking rocks with clothes on them.
