Time to pack

This is the end of the MSG-4 launch campaign. After about three months in French Guiana to support this fantastic adventure, it is time to pack and fly back to our respective places in Europe.

The outstanding performance of the ThalesAlenia Space team was the key factor for the success all along this MSG saga which started more than twenty years ago and that culminated with the successful launch of MSG-4, the last spacecraft of the series on July 15th 2015. MTG (Meteosat Third Generation) will be now, as explained in the introduction, the next milestone.

This last postcard flags also the end of this blog. It has been a pleasure to share with you this campaign step by step. We hope, with this (almost) daily reporting, to have kept you informed properly and that you have also enjoyed the "side" messages which tried to enlarge the usual engineering fields. If you found some interest in reading us, it is definitely our best reward.

We wish you all the best in your new projects and enjoy now a well deserved summer break! Good bye MSG, good bye to all.

From French Guiana with love.

Kirill B.

PS:
Last news from MSG: it goes (very) well, all planned operations are running nominally (See MSG-4 milestones page).
Last but not least, the first MSG-4 image, will be published early August when it will be released by EUMETSAT.

X - Forever spinning… Maelströms

Powerful phenomena observed in the nature such as volcanos, storms, tsunamis, hurricanes… have always been an endless source of inspiration for artists...

Hokusai's Great wave is one example among hundred others. The wave has not the exact shape of a vortex but gives however a quite scary impression: its power and its height are about to "swallow" the long (fishing?) boat and the sailors onboard… Life looks very frail and not much can be done against the power of the nature. This drawing also represents Mount Fuji in the background: a stable element contrasting with the transient move of the sea.

Maelström is a word from Scandinavian origin: could it lead us in a way to Edvard Munch? If in "The Scream", the Norwegian painter did not represent a maelström as such, the surrounding environment is definitely spinning as an echo of the high degree of panic of the screaming guy facing the public. The complementary colours (sea/sky - blue/orange) increase this effect of anxiety. In the background, the elevated water is whirling giving the impression of an upcoming disaster. Has this work something to do with the a mental perception of reality (the subject has no eye on this version)? At a certain distance on the bridge, two people seems to witness with indifference this hopeless situation...

Another example may be picked up in Edgar Poe's tale "A descent to the Maelström" (1841) translated into French by Charles Baudelaire and grouped with other novels under the title "Histoires extraordinaires". In this short story, a man tells his friends how he survived a terrible hurricane as his ship was caught in a vortex. This novel, considered as one a first Science fiction tale, was illustrated according to Wikipedia by Harry Clarkes in 1919.

From Earth to deep space...The Whirlpool galaxy gives a perfect example of the "organized chaos" in the universe. It is not sure which kind of ship or Noah's arch would resist or survive in a such maelström… Anyway, seen from remote, one can be amazed on one hand by the prowess of the technique to capture such an event and, on the other hand, by the artistic dimension of this picture.

Hyeronymus Bosch died in 1517, the same year Martin Luther initiated the Reform in Wittenberg. Europe at that time was strongly under Christianity influence, the only stable institution after the collapse of the Roman Empire. People's life was driven by fear of Hell and Heaven was promised to those meeting lifelong the principles prescribed by the religion. In the painting below Bosch illustrates this sequence after the death where an army of angels help the "good ones" to reach it. Funnily, Heaven is represented with a spiral shape with a bright center not so different from the whirling galaxy above. Of course, no conclusions can be drawn, but this pure fantasy representation of what is beyond our own borders may surprise by its modernity from an artist who evidently never observed the sky with the modern equipment we have today...

Due to the French national day on 14th of July, there were not enough resources at work in French Guyana required for a Launch. This means that the Ariane 5 launcher had to stay during this Bastille day on the ELA-3 launch pad. During these additional 24 hours, ThalesAleniaSpace performed few routine activities on MSG-4 (e.g. battery charging…). On the launcher side, the ventilation under the fairing will be continued in order to keep the critical items (tanks and batteries) under their required limits. This is necessary as the temperature under the sun during the day can be close to 40 deg. C. So far all monitoring measurements are well within the specifications required for the launch. It is noteworthy to mention that the weather this morning in Kourou was overcasted and rainy. The picture below gives a nice day view of the launcher on its launch pad.

From the S1B, the wall monitors give now live views of the launcher on its pad and also close up on  the Vulcain engine.

If everything goes well, tomorrow (15/07), 10 seconds before 18:42 (Kourou time, i.e 23:42 Western Europe time), Damien should pronounce from Jupiter 2 these well known and formal words:

-A tous de DDO,  Attention pour le décompte final, 10, ...

Follow with us the final chronology, tomorrow 15/07 starting from 07:30 am (Kourou time).

L-1 Launcher Roll Out

Today (13/07), the Ariane 5 Launcher to be used for the VA-224 mission (MSG-4/StarOneC4) has been transferred, as it was planned, from BAF (Batiment d'Assemblage Final/Final Assembly Building) to the Launch pad (ELA-3).

The pictures below give an impression of the Roll Out of the launcher taken from the Galilée building (excepted picture#1).

IX - Forever spinning… Hands on pottery

Potter/Potter's wheel at work

The potter's wheel has been spinning for donkeys ears and will still spin for long… As shown on the pictures above, the position of the hands shows the technic and the precision of the potter to give in fine the shape to the pottery. In life, hands are an important element of the in body language. It is the same in painting where hands play a major role in the overall expression of a composition; this is why they are often subject to dedicated studies preluding more achieved works...

1-For instance, Holbein made few sketches of hands before portraying Desiderius Erasmus at his writing table...

Left: Hans Holbein the Younger's Hand studies, Museum Boymans van Beuningen

Right: Hans Holbein the Younger (1497/98-1543), Erasmus writing (detail), 1523, Le Louvre

2-The Nicolas de Largilliere's Hand study/Etude de main, ca 1715 that is exhibited in Le Louvre shows  that hand sketches may even become a fully accomplished painting.

Nicolas de Largillière (1656-1746), Etude de main, Le Louvre

3-Jean Antoine Watteau invented at the turn of the XVIIIth century the genre of the fêtes galantes. In the detail of "Le faux pas", 1716/1718, shown below, a young girl is repelling the lover with her hand on his chest while he tries to embrace her. The expression in this scene results less from the face or the sight of the subjects than from the position of the bodies and the play with their hands: repelling or attraction?
For those familiar with the German silent Movie Menschen am Sonntag, mentioned in a previous post, this detail of Watteau' work may show a striking similarity with a crucial scene of the film... 

Jean Antoine Watteau (1684-1721), Le faux pas, 1716/17, Le Louvre

4-In Manet's In the Conservatory/Dans la serre, the hands of the two subjects are curiously placed right in the center of the painting. There is in this case no physical contact. The visible wedding rings on their hands shows a couple. They are in fact Mr and Mrs Guillemet visiting the winter garden of Count Otto Rosen in the VIIIth arrondissement of Paris. The two subjects are placed on each side of a bank backrest which creates de facto a separation in the various composition planes. In absence of eye contact between them (or with the observer), this couple looks rater distant, not to say feelingless rendering the overall atmosphere even heavy. Two elements come to balance this impression: the elegance of Mrs Guillemet in the foreground (ornamented hat, glove, tied ribbon, wristband, umbrella), and the decor of the winter garden in flower in the background. Is Manet just picturing a conventional bourgeois couple of the "glossy" Paris in 1879?
