http://www.bbc.co.uk/news/world-14077893 (the 'live' positions thing at the bottom) which currently shows the shuttle at 227km altitude and *descending" whilst the space shuttle is at an altitude of 400Km.

>Any elliptical orbit has an apogee (highest point) and perigee (lowest point). During travel from the former to the latter, the spacecraft's altitude is decreasing.
