SpaceSelfie.com is a free public service created by YouTube engineer Mark Rober and his STEM subscription company CrunchLabs, where you upload a digital selfie and it’s loaded onto their small CubeSat, SAT GUS. Once in low Earth orbit, SAT GUS captures an “off-world” shot of your photo with Earth’s curvature in the background, then beams the composite image back down so you can download your very own space selfie
