A Big Floating Iceberg? The "Object" seems to have an its own light/halo. Infact, during this sighting Atlantis and ISS were on the dark side above Australia. No "Alert of incoming/risk impact" and no Escape Procedure" was launched...
Tethers Offer Many Benefits to the ISS
Tethers can stabilize the attitude of the space station without propellant and with very little power
· ISS configuration is inherently unstable—short (~1-2 km), simple tether with guided boom provides gravity-gradient stabilization · Relieves CMGs and propellant req’ts for CMG desaturation ¨
A tether can provide standoff for an electric propulsion (EP) system to reboost the station ·
EP studies in the past have been stymied by plume impingement, thruster installation, plumbing, power consumption · An EP spacecraft on a short tether (~500 m) with its own power supply can provide reboost without these issues
A small electrodynamic (ED) tether system can reboost the station without propellant · Ionospheric current driven by solar power through conductive tether (~5 km) provides reboost force through magnetic interaction. · No resupply propellant requirements
A large electrodynamic tether system can reduce the inclination of the station · Electrodynamic forces can be used to provide out-of-plane forces needed to reduce station inclination. ¨ ISS can demonstrate tether technologies needed for robust exploration activities · ED tethers systems map into future momentum-exchange tethers for reusable, propellantless propulsion to GEO and the Moon.
Stainless steel disk flies in shuttles wake
Many shuttle experiments over the years have focused on developing or testing out new materials. One such study was the Wake Shield Facility (WSF), a 12-foot-wide (3.7-m), free-flying stainless steel disk. The WSF was designed to fly behind the space shuttle for several days, then be captured again. As the disk zipped through space, it would create a vacuum in its wake 1,000 to 10,000 times better than anything that can be achieved on Earth. The WSF would take advantage of this vacuum to grow extremely thin and pure films that could find applications in many different fields, such as the manufacture of semiconductors....

There's some very forced logic in your personal opinion.
Your point of view is 'self-illuminated.'
