************************
-> 7:20 a.m. - Part of Discovery's reaction control system, the rear 
steering jets control the orbiter during the early part of descent. As 
the orbiter transitions from spacecraft to aircraft, those jets are 
phased out as air pressure builds, and the orbiter's aerosurfaces become 
active.
7:17 a.m. - Current altitude is 213 statute miles.
7:12 a.m. - Over the next 30 minutes, Discovery will free-fall until it 
reaches Entry Interface, about 75 miles over the Cook Islands in the 
South Pacific. Current altitude is 220 statute miles. Post burn 
procedures are in work. Touchdown is one hour away.
7:09 a.m. - Burn complete! Mission Control reports a good deorbit burn 
-- no trim required. Expect Entry Interface at about 7:40 a.m. and 
landing at 8:12 a.m.
7:06 a.m. - The deorbit burn is underway! High above the western Indian 
Ocean, Discovery's two orbital maneuvering systems are firing for a 2 
minute, 42 second burn that will put it on a trajectory to Edwards Air 
Force Base. Discovery and her crew of seven are on their way home after 
the historic Return to Flight mission to the International Space Station!
7:01 a.m. - Five minutes until the burn. The first APU is up and running.
6:56 a.m. - Now 10 minutes away from the deorbit burn. About 5 minutes 
prior to the burn, Pilot Jim Kelly will activate one of three auxiliary 
power units. The remaining two will be activated after the burn, when 
Discovery has begun its descent. The auxiliary power units power the 
hydraulic systems that operate the orbiter's aerosurfaces, including the 
rudder, elevons and landing gear.

 active.
7:25 a.m. - Fifteen minutes until Entry Interface, when Discovery begins 
to feel the effects of Earth's gravity. Discovery's altitude is 175 
miles as it continues its descent.

7:40 a.m. - Now flying almost 400,000 feet above the Cook Islands in the 
South Pacific, Discovery is just beginning to encounter the upper 
reaches of Earth's atmosphere.
7:30 a.m. - Ten minutes until Entry Interface.
7:28 a.m. - All three of Discovery's APUs are now up and operating well.

7:52 a.m. - In its first of three roll reversals, Discovery is banking 
back to the right with its wings angled 75 degrees to horizontal. 
Discovery's current speed is 14,000 miles per hour at an altitude of 
217,000 feet.
7:50 a.m. - Discovery is traveling 15,400 miles per hour at 230,000 
feet. About 2,000 miles to Edwards.
7:46 a.m. - The rear steering jets have been activated; Discovery is 
beginning the transition from spacecraft to aircraft as it descends 
toward landing. The first roll reversal is coming up shortly.
7:45 a.m. - Discovery is beginning its first in a series of four banks 
that will help dissipate its speed as it plunges through the atmosphere. 
The first roll is to the left at 80 degrees to horizontal. The orbiter's 
nose is angled upward 40 degrees.
7:43 a.m. - Altitude 56 miles. Discovery is traveling 17,000 miles per 
hour and is less than 4,000 miles from Edwards Air Force Base.

 spaventoso.
non male per un aliante, eh?

7:59 a.m. - 470 miles to touchdown, speed 7,400 miles per hour. 
Discovery is banking back to the left, the third in a series of four 
steep rolls to help dissipate speed as it heads for touchdown.
7:56 a.m. - Traveling 17 times the speed of sound, Discovery is within 
1,000 miles of the runway at Edwards Air Force Base.

dai report si capisce come a ogni rollata lo shuttle rallenta.
il tutto solo frenando con la resistenza aereodinamica.
spaventoso...appunto :)

coraggio..quasi fatta...
8:02 a.m. - 10 minutes until touchdown. Discovery is in range of ground 
tracking and using Tactical Air Navigation (TACAN) data. There is one 
bank remaining in the series of four

8:13 a.m. - Wheels stop. "Happy to be back," Collins said to Capcom Ken 
Ham after he offered congratulations.
8:12 a.m. - Touchdown! Discovery is rolling out on runway 22 at Edwards 
Air Force Base!
Main gear touchdown, nose gear touchdown, chutes deployed... and 
Discovery is home.
8:10 a.m. - Commander Eileen Collins reports she has the runway in 
sight! Discovery's altitude is 17,000 feet -- 10 miles to touchdown.
8:07 a.m. - Discovery's wings leveling as it approaches the landing 
site. Now that the orbiter has gone subsonic, Commander Eileen Collins 
has assumed control. She'll fly Discovery on a 194-degree right overhead 
turn to align with runway 22.
8:04 a.m. - This will be the 50th landing of a Space Shuttle at Edwards 
Air Force Base. Eight minutes, 135 miles to touchdown.

tutto ok :)))))

Discovery, missione compiuta
atterraggio riuscito alle 14.12
CAPE CANAVERAL - La navicella Discovery è atterrata alle 14.12,
all'orario prestabilito. L'operazione rientro è perfettamente
riuscita, dopo il doppio rinvio, nella mattina, che ha costretto gli
uomini della Nasa a dirottare lo Shuttle dalla base di Cape Canaveral,
in Florida, a quella di Edwards, in California, sul lato opposto del
Paese.
Il rientro sarebbe dovuto avvenire ieri, ma il maltempo che ha
investito la Florida aveva costretto i tecnici della Nasa prima ad un
ritardo di 90 minuti, quindi al definitivo rinvio ad oggi. Stamattina,
altri due tentativi a vuoto, dovuti sempre al cattivo tempo, sino alla
decisione di spostare l'atterraggio al centro californiano di Edwards.
Discovery ha cominciato la manovra poco dopo le 13 italiane. Il
comandante Eileen Collins ha acceso i due razzi di manovra -
operazione che comporta una piccola frenata nello spazio - 300 Km
all'ora su una velocità di 29 mila - mentre la navetta sorvolava, a
354 km di altezza, il Madagascar. Lo Shuttle ha toccato l'atmosfera in
prossimità delle Isole Cook, in Oceania. Tutto bene anche in uno dei
passaggi più rischiosi, il momento di massimo calore.

Preferisco alianti con efficienze ben più elevate del 3:1 dello
Shuttle... ma forse sono invidioso!

complimenti al comandante collins che l'ha portato giu' come fosse un 
uccellino e non quel mattone da 56 tonnellate che e'. :)
