For those in the Houston area, there will be a unique opportunity to see the Space Shuttle, the Space Station, and a Russian Progress fly over head tonight (7/28/09). It should look like three stars (with the station being the brightest) moving across the sky just past sun down.

-------------------------------------------
Following the predicted undock of STS-127 from the station today, if the sky is clear tonight, we in Houston should be able to see STS-127, followed by the station and the Russian Progress 34P, flying in a line nearly vertically overhead from northwest to southeast beginning at 9:12 p.m. through 9:18 p.m. Each spacecraft will fade into Earth's shadow at an elevation of 26 degrees.
Path: 33 degrees above NW to 24 degrees above SE
Maximum elevation: 78 degrees

The International Space Station Trajectory Operations Group (TOPO) provides updates via JSC Today for visible station passes at least two minutes in duration and 25 degrees in elevation. Other opportunities, including those with shorter durations and lower elevations or from other ground locations, are available at the Web site below.
