Patch STS-125, ultima "Hubble Servicing Mission"

Ecco il patch di missione, molto sobrio.

Decisamente…mi sarei aspettato qualcosa di più per una missione del genere… :-s :? che magari sia una bozza?

No, dovrebbe essere il definitivo.

A me non sembra male… chissà perchè non trovo critiche ai patch di missione :stuck_out_tongue_winking_eye:

Approposito di questa missione, ho trovato questo articolo che mi sembra davvero interessante riguardante l’addestramento degli astronauti…

Goddard Engineers and Divers Multi-Task for Hubble

Ever wonder how NASA astronauts prepare for Hubble Space Telescope servicing
missions? I wish I could say it’s rocket science, but what it really comes
down to is lots of preparation. And the astronauts spend many hours
practicing on intricate, full-sized models of the telescope.

In planning for Servicing Mission 4 to Hubble, crew members divide their
time between NASA’s Johnson Space Center, Houston, working underwater on a
Hubble mock-up to simulate the effects of weightlessness, and NASA’s Goddard
Space Flight Center, Greenbelt, Md., where they practice scheduled mission
tasks on a Hubble mock-up inside a large clean room facility.

“When servicing Hubble, spacewalking time is our most precious resource,”
said Mike Weiss, Hubble’s Technical Deputy Program Manager at Goddard.
“Every second counts, so every activity performed by the crew must be
meticulously engineered, choreographed and practiced ahead of time.”

The best way for the astronauts to be able to do the most during their
limited spacewalks is to practice on intricate models of Hubble. One such
model is in a huge water tank at Johnson. This water environment closely
replicates the weightlessness of space, allowing the crew to perfect their
techniques so by the time they actually reach Hubble there are few or no

The astronauts’ earthly practice sessions help them prepare for any issues
they could face once they open Hubble’s bay doors and begin working.

“During the mission the astronauts perform on-orbit tasks inside Hubble,
wearing bulky, pressurized gloves and under lighting conditions that are not
always optimal,” said Justin Cassidy, Crew Aids and Tools Lead Systems
Engineer at Goddard.

The mock-ups of the telescope are so precise that the crew becomes acutely
aware of how they need to move and how much clearance they will have once
they get inside of Hubble. And since each spacewalking task is unique, the
team develops new tools and crew aids that ensure the job gets done as
easily and efficiently as possible.

“It’s not enough to assume that since a past spacewalk went well, the next
will too. Every time we do a mission, there’s always a new task that hasn’t
been done before so we often have to make new astronaut tools,” said
Cassidy. “Consequently, there is a constant need for a facility where space
walking procedures can be developed and ideas and equipment can be tested.”

Such a place is the Neutral Buoyancy Laboratory (NBL) at Johnson. The NBL
houses an enormous water tank. This 202-foot-long by 102-foot-wide by
40-foot-deep structure contains a whopping 6.2 million gallons of purified
water that is completely filtered and recycled every 19.5 hours, providing
the astronauts and NASA divers with exceptional water clarity.

Working underwater closely simulates the weightless environment encountered
by spacewalking astronauts. The underwater environment helps them learn how
to position their bodies and how to maneuver themselves during an EVA, or
spacewalk. Since they are actually in pressurized spacesuits, they also have
an opportunity to evaluate reach, access and visibility to specific work

While being underwater comes pretty close to replicating the effects of
zero-gravity, water drag can be a hindrance, making some things easier to do
in the water than in space and other tasks more difficult. In order to
compensate for this “negative” training, astronauts receive additional
training on a special air-bearing floor at Johnson in order to learn the
effects of dealing with large masses in space.

Goddard’s Role

The Hubble team refers to underwater engineering development and flight
training as “dive runs.” The team will complete about 12 dive runs before
the scheduled August 2008 mission to Hubble.

According to Weiss, every hour of work performed during an actual spacewalk
equals about 20 hours of underwater engineering development. Once NASA
assigns an astronaut crew and the engineering products are turned over to
the astronauts’ training team for actual flight training, the crew then
spends about 14 hours training under water for every hour they actually
spend performing spacewalking tasks.

Goddard provides Hubble engineers who dive with the astronauts to define
procedures and tool requirements as well as training the crew in the use of
the tools and crew aids. Johnson supports the dive runs with safety divers,
who ensure the crew’s well-being, and video photographers and still
photographers that document the crew’s activities. The team then studies the
images captured in the tank to evaluate each run and modify tool designs,
which increases efficiency.

But how did the Goddard engineers get involved in diving? “Way back, when we
were going through engineering development for the first servicing mission,
we decided that instead of hiring divers we’d have to train on Hubble
terminology, mechanical operations and complexities of the interfaces, and
then have them debrief us on what they learned underwater, it would be more
efficient to just put our engineers in the water,” said Weiss. “This
efficiency allowed the Johnson divers to focus on their primary duties.”

“The divers that Johnson supplies us at the NBL are wonderful,” elaborated
Cassidy. “But since operations and hardware change so much it would be
impossible for them to keep up with all the new developments. It’s extremely
important that we bring our own people who are intimately familiar with the
ins and outs of a particular dive run.”

As the Center primarily responsible for Hubble servicing development,
Goddard manages all pre-dive development and keeps its designs up-to-date
during the testing period leading up to launch. It is not unusual for the
team to make tweaks to tools and crew aids after each run. By having the
Goddard engineers experience the dive runs along with the astronauts, the
entire team gains instant insight into what improvements are needed.

“Rather than just developing drawings and building and testing hardware for
the Hubble mission, our engineers get up close and personal with the crew,”
remarked Mark Hubbard, Deputy Carrier Manager for Hubble at Goddard and team
diver. “When I dive, it’s almost like I’m in space with the astronauts, so I
get a sense of what they need to do in order to accomplish a particular

Hubbard equated the dive experience to learning a subject in school. “When
you are in school, you learn a lot from books, but the actual hands-on
experiences help things really sink in.”

The Dive Experience

A typical dive at the NBL involves two astronauts and about 20 to 25 people,
all focused on a particular spacewalking task. With such a high volume of
bodies in the tank, it becomes a veritable beehive of divers swarming around
the astronauts.

Despite the number of people in the tank, the Goddard divers still have the
ability to interact with the astronauts when their guidance is needed. And
since communications between astronauts and divers is somewhat limited (the
astronauts are fitted with microphones, whereas the divers are not),
immediately following each dive, all participants go topside for a
debriefing. This after-dive meeting enables necessary dialogue between the
Goddard engineers and astronauts to discuss in detail what they observed and
how they can make future dive runs more efficient.

Currently, about 25 Hubble personnel are certified to dive in the NBL. A
group of four Hubble divers rotates in two-hour shifts during a simulated
six-hour EVA dive run. This once in a lifetime experience comes with high
expectations, though. The Hubble divers are tasked with ensuring that each
spacewalk will be executed as safely and efficiently as possible.

Asked what Hubbard finds most rewarding about his unique opportunities with
the Hubble mission he said, “I was in the water one day preparing for a dive
just looking around and realizing here I am in the space program and it
just struck me, this is incredible! Not too many people get to do stuff like
this. Here I am working side-by-side with these extraordinary men and women
who most people only get to read about in newspapers and magazines.”

Molto interessante…

Ah, dimenticavo, la patch la trovo molto bella.
E significativo lo Shuttle che si allontana… :frowning:

Tutte le PACH riguardanti le missioni Shuttle sono belle o state belle; forse l’unica un poco “pietosa” è stata quella della STS-58 .
Per quanto riguarda questa dell’ultima missione all’HUBBLE, la trovo molto carina!

:offtopicplus: E’ sicuramente questione di gusti, ma non la trovo tanto meno bella di altre. Personalmente la palma della patch più brutta la dò a quella della Expedition 1 della ISS (vedi:

Quella di STS 58 aveva i colori secondo me bruttini ed era rovinata dalla grafica.
D’altra parte, la simbologia è molto bella (come in tutte le patch, ma da medico qusta mi aveva colpito): infatti sul perimetro, a destra e sinistra c’è il caduceo medico e veterinario (è lo stemma col bastone e il o i serpenti delle farmacie :smile:), attorno alla navetta la doppia elica del DNA e per una patch la inusuale forma esagonale degli anelli di carbonio.
maggiori dettagli su questo link:

Per quanto riguarda la patch di STS 125 a me sembra molto bella, sobria come dice Alberto: molto appprezzabile il riferimento all’universo profondo nel campo azzurro abbracciato da Hubble.

Piuttosto non l’avevo mai detto ma quella di STS 122 mi piace pochissimo… :bi:

Ciao a tutti! :stuck_out_tongue_winking_eye:

è il simbolo del “primo medico della storia” Ippocrate ^^ (quello del giuramento),
viene dal suo mito :smiley:

in realtà il bastone col serpente è il bastone di Esculapio, dio greco-romano della medicina.
Ho parlato di uno o due serpenti, perche nelle farmacie si vede spesso il caduceo (con 2 serpenti) che era simbolo del commercio e non aveva nulla a che fare con le scienze mediche.
