Landings are all manually flown but the autoland has been tested on a few missions I believe. Normal glideslope is about 20-22 degrees depending on weight and is maintained until around 1500ft agl when a flare to 3 degree "inner" glideslope is made to bleed off speed and arrest the huge rate of descent. 20 degrees equates to 7 miles out at 12,000ft so it's pretty steep, overhead the airfield at 40,000ft to touchdown is about 4 minutes.
