Shenzhou 8 Mission Could Top Three Weeks

illustration only
by Morris Jones
Sydney, Australia (SPX) Feb 17, 2011
The next flight of China's Shenzhou spacecraft will
last somewhere between 20 and 22 days, according to German sources. The
information was relayed to SpaceDaily by a communications officer at
DLR, Germany's equivalent of NASA. German researchers will fly a
collection of biological experiments on the mission, which is expected
to launch in the second half of this year.

The Shenzhou 8 spacecraft will fly with no crew on board, and will be
sent to rendezvous and dock with China's Tiangong 1 space laboratory,
expected to be launched at some time before Shenzhou 8 flies. The
descent module of Shenzhou 8 will return to Earth at the end of the
flight, carrying the experiment package.

The duration of the mission is noteworthy. This will be the longest
flight ever for a Shenzhou spacecraft in its full capacity. It also
gives clues to how China will send astronauts to the Tiangong 1
laboratory, and other space laboratories to follow.

The primary purpose of the Shenzhou 8 mission is to test rendezvous and
docking procedures in space. It's also a dress rehearsal for the
Shenzhou 9 mission, which is expected to carry astronauts to the
Tiangong 1 laboratory in 2012. Thus, we can expect the overall mission
plans to match each other fairly closely.

China has openly discussed its plans for sending astronauts to its first
space laboratory for years, but has released few specific details on
the missions.

One question that has preoccupied analysts is the expected duration of
an expedition to Tiangong. The space laboratory is fairly small, and
offers little room for astronauts to inhabit. Questions have also been
raised about the logistics of such a mission.

The Tiangong laboratory and the Shenzhou spacecraft that will dock with
it have fairly limited room for supplies. Issues of food, water and
oxygen supplies would almost certainly rule out a long stay aboard the
laboratory.

This writer, along with other analysts, has previously
suggested that a crewed flight to Tiangong of roughly two weeks was
likely. Some analysts suggested around three weeks. A three-week mission
for Shenzhou 8 supports all these estimates, but still doesn't tell us
exactly how long the Shenzhou 9 mission will last.

If Shenzhou 8 is meant to be a shakedown cruise for a crewed expedition,
it will try to be thorough in its testing. This means that we can
expect this to cover all of the normal requirements for a crewed
mission, plus a bit more. So Shenzhou 8 is probably going a bit further
with its endurance, to prove that it's spaceworthy for a long time.

This mission is probably designed to last a few days more than will be required for a crewed flight, just for good measure.

If this is the case, then astronauts will probably stay aboard Tiangong 1
for roughly two weeks. A stay of around two and a half weeks is
possible.

At this stage, it is unclear how long Shenzhou 8 will fly alone at the
start of its mission, while it approaches Tiangong 1. It's possible that
they will copy current Russian strategies, and cruise for about two
days to the laboratory.

However, China is also introducing a more powerful version of the Long
March rocket to launch this mission, and may opt for a more direct
trajectory. If crew consumables are scarce, it makes more sense to get
to the laboratory as quickly as possible.

Then again, Shenzhou 8 is doing this for the first time, and it's also a
modified vehicle. There will probably be a solo "shakedown cruise" in
orbit before the spacecraft is cleared to move on to the docking phase
of its mission.

On a crewed flight, the time spent in transit will influence the time
available on the laboratory. But we can't be sure if Shenzhou 8's cruise
will match that of Shenzhou 9.

So, we can probably say for sure that crewed expeditions to Tiangong 1
will last no longer than three weeks. Exactly how much time will be
spent on board the laboratory is unclear. But the mission plan suggests
that China is determined to get as much crew time on the laboratory as
it can, given the resources available.

La préparation de SZ-8 est en cours. Sur la photo une équipe est en train d'effectuer des tests sur le système d'auto-diagnostic. Sur la veste des personnels on voit "2011 Mission de RDV & Arrimage".



Si tout va bien le lancement de SZ-8 est dans 15 jours.

[montmein69]

Cadence de tirs plutôt élevée.
Je suppose que les chinois ont hâte, si le RDV en automatique valide les procédures et montre une "station" en bon état à tout point de vue, d'y envoyer le schenzou suivant avec un équipage prenant possession de la station. A la fois une réussite technique qui valorise le gouvernement chinois envers sa population, et aussi un coup médiatique important au regard du reste du monde.

Bah merde ils trainent pas eux.

SZ-8 est prêt, la fenêtre de lancement aurait été fixé au 1er Novembre à 5h du matin heure locale.

Shenzhou-8 flight project of Daniela Grimm and team

Shenzhou-8 flight mission within the Chinese space flight program.

We plan to investigate the thyroid carcinoma cell line ML-1. We already
performed investigations under conditions of simulated microgravity and
could see that these cells start to go into apoptosis. They also grew in
form of multicellular spheroids, whose behaviour is comparable to
metastases in nude mice.
We intend to investigate the cytoskeleton,
extracellular matrix proteins and pathways of apoptosis and compare
these results to former studies which have been performed with the help
of a Random positioning machine.

Moreover, we will investigate the release of cytokines and other soluble factors in the supernatant
(Collaboration with Dr. Sarah Baatout, SCK•CEN, Mol, Belgium).

La fusée CZ-2F-Y18 avec SZ-8 ont quitté le hall d'assemblage et de test et arrivent au pas de tir. L'agence Xinhua dit que la date de lancement est au "début de Novembre".

Lancement à priori prévu le 31 Octobre 2011 à 21:57:27 UTC.

Très étrange la masse du lanceur CZ-2F est passé de 493t pour TQ-1 à 499t pour SZ-8.

[patchfree]

Peut-être que la masse du Shenzou-8 est un peu plus importante et qu'ils ont augmenté en conséquence la quantité d'ergols dans la fusée. Mais je ne connais pas les caractéristiques de la fusée et je ne sais pas si c'est possible ou si elle est au max de ses possibilités.
