The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
On the nasa stereo scope ahead hi2 on may 11th 2018, to the current date july 12th 2018. the nasa stereo scope has captured a ufo on it heading inwards toward earth’s direction it seems. i first noticed the object because it looks like a wheel with a cross in the center of it. when entering the dates on the site. you can only view 28 days a time. so watch 20180511-20180625 then watch the 20180625-20180712. it is still viewable on the scope. reminder, these pictures were captured by a nasa observation satellite.
