Phobos et Deimos, les satellites de Mars

Harumph. The lovely French image of Mars, Phobos and Deimos has vanished.

Whoops! It's back again!

Vleeptron has found another one -- an amazing marriage of Astronomie and Arte -- specifically the fabric crafts.


Judy W. Ross of Point Roberts, Washington State USA, and Roberts Creek, British Columbia, Canada, begins each day by gazing at NASA's Hubble photo of the day, and was inspired to make a quilt based on the photos.

This is her square of Mars and its moons Phobos and Deimos. The whole quilt is magnificent -- you can click on any square -- and was featured as the NASA astronomy picture of the day on 17 October 2003. It received the Creativity Award at the 2003 Sunshine Coast Quilt Guild show in Sechelt, BC, and was featured at the fourth annual Fibre Arts Festival in Gibsons, BC. The quilt [spent] the summer of 2004 on display at the Lick Observatory, Santa Cruz, California. Copyright Judy W. Ross.

Mars is the god of War. His two attendant godlings are Phobos (fear) and Deimos (panic).

===============================

Mars possède deux petits satellites, Phobos et Deimos, de forme irrégulière (voisine d'une ellipsoïde) et criblés de cratères.

Voici une vue de Deimos.

Certains astronomes les considèrent comme des corps semblables à des astéroïdes, capturés par la planète au tout début de son histoire.

Ceux-ci ont été découverts par Asaph Hall, le même jour en 1877.

On remarque qu´ils gravitent à une faible distance de la planète.

Phobos mesure environ 21km sur son axe le plus long et Deimos 15km.

Comme Phobos, Deimos ressemble beaucoup a un astéroïde sans doute capturé par Mars: il est essentiellement fait de composés carbonés et d´eau.

* Distance de Mars: 23,460 km
* Taille moyenne: 10 x 12 x 15 km
* Magnitude visuelle: 12.7
* Période de révolution: 1 jour 6 heures
* Vitesse orbitale: 1.4 km/s
* Inclinaison de l´orbite sur l´équateur de Mars: 1 à 3°
* Excentricité de l´orbite: 0.0002
* Masse (Mars = 1): 3/100,000,000
* Densité (eau = 1): 1.7
* Vitesse d´évasion: 6 m/s
* Réflectivité (albédo géométrique): 0,07

==================

Voici une vue de Phobos.

En 1988, les Russes envoyèrent deux sondes sur le satellite Phobos. Les deux missions échouèrent, bien que l'une ait pu retransmettre certaines données et photographies avant que le contact radio ne fût perdu.

Phobos ressemble beaucoup à un astéroïde : il est essentiellement fait de composés carbonés et d´eau.

* Distance de Mars: 9,380km
* Taille moyenne: 18 x 22 x 26 km
* Magnitude visuelle: 11.6
* Période de révolution: 7 h 40 m
* Vitesse orbitale: 2 km/s
* Inclinaison de l´orbite sur l´équateur de Mars: 1°
* Excentricité de l´orbite: 0.015
* Masse (Mars = 1): 2/10,000,000
* Densité (eau = 1): 2.2
* Vitesse de libération: 10m/s
* Réflectivité (albédo géométrique): 0.06

Now I for one LOVE this Planet.
Had to do a lecture on it on what you call Prom Night in front of half the Village. vleeptron must also buy the 2DVD set from the BBC called Planets. Incredivble stuff.
btw Would you sing a petition asking NASA that one of the craters on Mars would be named after ray Bradbury? he'd bloody deserve it.

In the mean time and because I just could not resist.........here's the MISFITS GOING ONE TWO THRE FUH
Oh go
Possession of the mind is a terrible thing
Its a transformation with an urge to kill
Not the body of a man from earth
Not the face of the one you love, cause

Well, I turned into a martian
Woah oh oh
I cant even recall my name
Woah oh oh
Times I never hardly sleep at night
Woah oh oh
Well, I turned into a martian today

I walk down city streets
On an unsuspecting human world
Inhuman in your midst
This world is mine to own, cause

Well, I turned into a martian
Woah oh oh
Well, I cant even recall my name
Woah oh oh
Times I never hardly sleep at night
Woah oh oh
Well, I turned into a martian today

Go go

Well, I turned into a martian
Woah oh oh
Well, I cant even recall my name
Woah oh oh
Times I never hardly sleep at night
Woah oh oh
Turned into a martian
Woah oh oh
Cant even recall my name
Oh, wont you tell me what the fuck is my name, martian
Woah oh oh
Woah oh oh

here's Jonathan Richman's song about the Martians coming to visit Earth (probably Boston)

I just love this guy. It's a testament to the generosity of Earth that he doesn't seem to need a day job to survive. He's the guy who wrote the song about Pablo Picasso and rhymed

Well the girls would turn the color of an
avacado
When he's drive down the street in his
El Dorado

========

Here come the Martian Martians
Jonathan Richman & The Modern Lovers

Here come the Martian Martians
And they're riding on their Martian bike
Well, we have to find out right now
What kind of ice cream do the Martians like?

Here come the Martian Martians
Why staying in such a cheap hotel?
Maybe we should help out the Martians
Looks like the Martians ain't doin' too well

Martian time time time
Well, it's Martian rhyme time
We got a Martian rhyme for Martian Martian time

Well, here come the Martian Martains
They're trying to fight with rocks and sticks
Don't the Martians know better?
Looks like they're up to their same old tricks

Well, here come the Martian Martians
They got notebooks in their hand
What are they trying to write down?
I guess they must be strangers in this land.

Well, here come the Martians
Baking up a Martian cake
We better find out right now
What kind of flavor do these Martians make

Well, here come the Martian Martians,
There're Martian schoolgirls too
Well, I like the Martian schoolgirls
And I hope they like me too
Martian rhyme rhyme rhyme
It's Martian time time time
You got the Martian rhymes for Martian Martian time

The Martians have notebooks in their little hand
Because they're strangers in this land
Martian rhyme, it's Martian Martian time

Well, here come the Martian Martians
Well, they're baking up a Martian pie
I hope the Martians like me
And give some to I

Well, here come the Martian Martians
Well, they're setting up a Kool-Aid stand
Where's their financial advisor?
Somebody should take him by the hand

Martian rhyme rhyme rhyme
Martian time time time
You got a Martian rhyme for Martian Martian time
And the Martians have notebooks in their little hand
They're still strangers in this land
Martian rhyme, it's Martian Martian time

Nice merge with the astronomical art!

Dame RheLynn, glad you liked it!

My wife S.W.M.B.O. is an expert fabric craftswoman. I know the sheep names of many of my sweaters, she does it all from shearing to dying (using nasty now-illegal colonial mordants) to spinning to making me stand around like a jerk while she measure the sweater-in-process.

She also quilts, and so I've come to appreciate this remarkable body of art.

Isn't this Mars/Phobos/Deimos Quilt just gorgeous? What a beautiful marriage of Astronomy and Fabric Crafts!

Now check this ethereal, sublime sucker out, the Marriage of Fabric Crafts and the Anti-Slavery Movement!

I am just wildly guessing that you know what The Drinking Gourd is/was.
