[Space] NASA - STS-125 - HST SM-4 (Atlantis)

[GioFX]

Oltre a NASA TV segnalo che anche durante questo lancio (e speriamo con meno problemi rispetto alla passata missione) SFN offre il suo live coverage video:

1730 GMT (1:30 p.m. EDT)
The inspection team is heading back to the Launch Control Center now.
"We think from what we're can tell so far we're probably 'go,'" NASA commentator George Diller says. "But we have to be able to prove it. So that's why we're waiting for them to get back and we can see the pictures they've taken and see their data."

[GioFX]

1748 GMT (1:48 p.m. EDT)
NASA launch director Mike Leinbach has conducted his poll and given approval to resume the countdown for liftoff at 2:01 p.m. EDT.
"It's a great day to go fly," Leinbach told commander Scott Altman.

1752:56 GMT (1:52:56 p.m. EDT)
T-minus 9 minutes and counting! The Ground Launch Sequencer has been initiated. The computer program is located in a console in the Firing Room of the Complex 39 Launch Control Center. The GLS is the master of events through liftoff. During the last 9 minutes of the countdown, the computer will monitor as many as a thousand different systems and measurements to ensure that they do not fall out of any pre-determine red-line limits. At T-minus 31 seconds, the GLS will hand off to the onboard computers of Atlantis to complete their own automatic sequence of events through the final half minute of the countdown.

1800:25 GMT (2:00:25 p.m. EDT)
T-minus 31 seconds. AUTO SEQUENCE START! The handoff has occurred from the Ground Launch Sequencer to the space shuttle. Atlantis' computers now controlling.
In the next few seconds, the solid rocket booster hydraulic steering system will be started, the orbiter's body flap and speed brake moved to their launch positions, the firing chain armed. Main engine ignition begins at T-minus 6.6 seconds.

[GioFX]

1801:56 GMT (2:01:56 p.m. EDT)
T-minus 10 seconds, go for main engine start, T-minus 7, 6, 5, engine ignition, 3, 2, 1 and LIFTOFF! Liftoff of space shuttle Atlantis on a final mission to renew astronomy's greatest observatory, the Hubble Space Telescope!

[GioFX]

1810 GMT (2:10 p.m. EDT)
T+plus 8 minutes, 43 seconds. MECO. Main Engine Cutoff confirmed! Atlantis has reached its preliminary orbit for the long-awaited servicing mission to extend the life of the Hubble Space Telescope into the next decade.

The shuttle astronauts will conduct five straight days of spacewalks to install a pair of new scientific instruments into Hubble, attempt ambitious repairs on two failed instruments, replace the observatory's original 19-year-old batteries, plus exchange other internal components.

[GioFX]

1811 GMT (2:11 p.m. EDT)
T+plus 9 minutes, 30 seconds. It was a nominal MECO. A quick boost from the Orbital Maneuvering System engines is not required to reach the planned preliminary sub-orbital trajectory.

Finita così la diretta?! Pensavo facessero una maratona

Ma intendi la diretta della NASA? NASA TV segue tutte le missioni, ora sta mostrando i replay del lancio... SFN continua ancora per un pò, almeno fino alla Post Launch Press Conference.

[GioFX]

1823 GMT (2:23 p.m. EDT)
T+plus 21 minutes, 10 seconds. The upcoming orbit adjustment burn will is scheduled for T+plus 43 minutes and 45 seconds.
After the eight-and-a-half-minute climb to space, Atlantis achieved a suborbital trajectory with a high point of 334 miles and low point of 33 miles. A two-minute firing of the twin orbital maneuvering system engines on the tail of Atlantis will raise the orbit to 342 by 125 miles, inclined 28.5 degrees to the equator.

Sono curioso di sapere qualcosa di più sul sensore che funzionava male durante l'ascesa.

1847 GMT (2:47 p.m. EDT)
T+plus 45 minutes, 33 seconds. The twin OMS engines on the tail of Atlantis have been fired successfully to propel the shuttle the rest of the way to orbit. The new orbit is targeted to have a high point of 342 miles and low point of 125 miles.

Final servicing mission begins to extend Hubble's life

With a second shuttle on standby for possible rescue duty, the shuttle Atlantis blasted off Monday on a high-stakes five-spacewalk mission to resuscitate the aging Hubble Space Telescope, a fifth and final housecall to give the hobbled satellite a new lease on life.

Initial examination of video and film taken of the launch is getting started.
"At this point, there's absolutely no imagery observations indicating any concern at all," the CAPCOM just radioed the shuttle crew from Mission Control.

"That's outstanding, Houston. Thanks for that early word," commander Scott Altman replied.

Si parlavo di NASA Tv, non capisco perché hanno rifatto vedere il lancio. Dato che non atraccano alla ISS come fanno a controllare lo scudo termico?!

Si parlavo di NASA Tv, non capisco perché hanno rifatto vedere il lancio.

I replay li fanno vedere dopo tutti i lanci perché si conclude il collegamento video e nel periodo successivo non succede niente di eclatante.

Dato che non atraccano alla ISS come fanno a controllare lo scudo termico?!

Mancando la ISS non possono fare la "classica" ricognizione fotografica, ma l'Orbiter Boom Sensor System è comunque sufficiente a ispezionare lo scudo termico.
