Re: 2040 : Mars Two

Stressful! Is it very loudly or, on the contrary, silent?
(it would be fun to render a traveling shot...)

Re: 2040 : Mars Two

Like all Machines room, it's hot and noisy.

Here are the pumps of propellant (red) and these of comburant O² (blue) coming of external tanks.

Re: 2040 : Mars Two

On 01/01 we saw ISV Hermes in the night sky, here we see the Ares Vallis and the Taytay crater from the space.


Model made with SH3D and scenery (1800 x 800) with Celestia

Did you see the base camp (white dot under Hermes) ?
It's better in a dark room.

Re: 2040 : Mars Two

The last part of the Machines room : the core.


1024 x 768 in Q4

Behind the green wall there are the chambers of the plasma thrusters.

And the model 3d is HERE

Re: 2040 : Mars Two

Thanks Aeowyn, it comes from ST Universe.

some orbits later in day light but with a different horizon, you see Ares Vallis and the Taytay crater
(on down right of the accomodation ring).


SH3D (1800 x 900 in Q4) for the model and Celestia for the background.

Near 500 MB (uploaded by a friend) for a video of ISV Hermes (640 x 480 for 17 sec), see HERE from YouTube...

Made with Celestia (and it moves !).

Re: 2040 : Mars Two

Thank you Betty. smile

Take little heights over Taytay crater with the drone, you see Ares Vallis.



More meters, you see all the crater and the Ares Vallis at left (with Google mars). applause

Re: 2040 : Mars Two

A little pedagogy today, we will approach astronautics...

Calculations for a Martian launch:
A little physics, let us remember these data:



Postulate:
Let's take 2 digits after the comma
Terre = Earth = blue
Mars = red
A real case: Mars Pathfinder
Therefore, with the hypothesis of a circular orbit and in the same plane (Less precise approximation for Mars than for Earth).

Departure on December 4, 1996

Picture from Celestia

Arrival 7 months after (212 days) on July 4, 1997


Instant of launching :
But where should Mars be on launch day ? thinking
Mars achieves a full 360° orbit in 1.88 years (or 687.67 days).
 
Formula: Circle × ((DS / DE) / PM) where:
Circle (in Deg) = 360
DS = Travel time in days
DE = One terrestrial year in days = 365.25 days
PM = Relative Martian period in terrestrial year = 1.88
this gives :
=> 360 x ((212 / 365.25) / 1.88) = 111°14 for Pahtfinder
=> 360 x ((180 / 365.25) / 1.88) = 94°40 for Mars II
 
We can calculate the relative position of the Earth and Mars.
180° - 111°14 = 68°85 for Pathfinder (validated by first picture) applause
180° - 94°40 = 85°60 for Mars II
 
Thus, launches are only possible when the Earth is located at 85°60
Behind the planet Mars (for Mars II in 2039).
 
For Mars II
Departure around june 10th 2039 (+/- 1 day)

The picture from Celestia gives the positions of Earth and Mars at the time of departure.

Arrival around Dec 07th 2039 (+/- 1 day) near 2040... blushing

The picture gives the positions of the Earth and Mars at the moment of arrival.

The calculations will be the same for Mars III.
When do you think that Mars III will arrive on Mars ?
I wait your answers (with average of + or - 2 days)...

The winner will become one of passengers of the next mission. rolling eyes

cool
