The shuttle, which had been circling the earth
upside down with its engines facing forward,
flipped to face its nose forward
and its cockpit upward for landing.
As it entered the atmosphere, superheated gas
known as plasma heated the outer surfaces of the craft
to about 3000 degrees Fahrenheit,
and the shuttle executed a series of computer-controlled S-curves
that helped it to slow to landing speed.
Those below heard a characteristic twin sonic boom
generated by the nose and wings
as the shuttle neared the Kennedy Space Center landing strip
at supersonic speeds.
Because the shuttle comes back to earth as a glider,
flying it is famously tricky.
In a 2004 memorandum to shuttle workers,
N. Wayne Hale, Jr., the manager of the shuttle program,
wrote, “The orbiter flies like a brick,
with handling qualities that would make a Mack truck proud.”
At dawn today at the Kennedy Space Center,
there were thunderstorms about 40 miles to the north
that threatened to scuttle landings for the day.
But just before 8, the message came from Houston
that weather was not a concern,
and the Discovery’s commander and pilot
were given the green light
to bring the shuttle...back to earth.
“Discovery, Houston, good news,”
Mr. Frick told Mr. Lindsey.
“You’re go for the de-orbit burn.”
“Roger that,” Col. Lindsey replied.
“Go for the de-orbit burn.”
The astronauts also prepared for landing by drinking
between 8 and 12 ounces of fluid every 15 minutes,
in order to increase the amount of fluid in their bodies.
