Very interesting picture from the NASA archives which seems to show multiple orbs or perhaps a single object orbiting the Earth. This picture was snapped during the STS-100 mission.
STS-100 was a Space Shuttle mission to the International Space Station, to install the ISS Canadarm 2 robotic arm, flown by Space Shuttle Endeavour.
