TITO REFLECTS ON HIS TRIP TO PARADISE
Now safely on the ground, space tourist Dennis Tito is recovering nicely from his controversial 8-day flight to the International Space Station. To say he had a good time would be an understatement, "it was paradise, a great flight and great landing, there were absolutely no difficulties." During a recent press conference in Moscow, Tito noted that he would have loved to have stayed on the station for months, and he had nothing but words of encouragement for anyone who would like to follow in his expensive footsteps.

SEA LAUNCH SUCCESSFULLY FIRES XM satellite INTO ORBIT
Sea Launch placed the second XM digital radio satellite into space on Tuesday, on board a Zenit 3SL rocket. The booster launched from a position on the Equator in the Pacific Ocean at 2210 GMT (6:10 pm EDT), and separation of the satellite occurred approximately an hour later. Once in position, the XM satellites will deliver digital radio services to subscribers across the United States.
CHANDRA VIEWS THE EDGE OF A BLACK HOLE
Using the incredibly powerful optics of the Chandra X-Ray Observatory, Astronomers have determined that the accretion disk around a black hole stops much further out than predicted. Previously estimated to get as close as 40km, the accretion disk - where matter swirls around the black hole in a flat disk before it plunges into the singularity - was recently measured to get no closer than 1000km. The scientists' rationale for the distance is that as it gets any closer, all matter bubbles into a hot gas before it's pulled into the hole.
