User's guide, tutorials, documentation / Steam Autopilots
« on: March 09, 2018, 07:47:32 AM »
We made an extensive list of autopilots to assist in common mission maneuvers. Some autopilots are specific to the Apollo missions, some are generic.

When a green dot shows next to the AUTOPILOT tab, an autopilot is currently running.
Some autopilots run in a safe mode. You need to press the padlock icon to unlock.
Some autopilots start in paused mode. You need to first select the required parameters and then press the start button to begin running the autopilot.

AGC TEST (Program 7) Performs a basic display test on the Apollo Guidance Computer

LAUNCH TO ORBIT (Program 11) Launches the Saturn V stack to Earth parking orbit. 'Altitutde' is the orbital altitude in kilometers and 'Bearing' is in degrees from true north. The spacecraft must be launched from a port, ie, the Kennedy Space Center launchpad.

LAUNCHMOONORBIT (Program 12) Launches the Lunar Module to lunar orbit with the correct inclination.

TLI LUNARINJ (Program 15) Fires the S-IVB engine into translunar injection orbit. This requires the spacecraft to be within 1 degree of the orbital plane with respect to the Moon. It will propel the Apollo stack to an orbit with an apogee nearing the distance at which the lunar sphere of influence will trap the spacecraft. Upon nearing the Moon, further mid-course corrections may be needed to finetune the lunar orbit insertion. In reality, this TLI was performed by the Instrument Unit on the S-IVB stage and the AGC program 15 (this one) was a backup.

LOI LUNARORBIT (Program 16) Computes and performs the engine burn required to get trapped in lunar orbit. It assumes the spacecraft is following a hyperbolic orbit (an open orbit where eccentricity is greater than 1).

LUNAR DOI (Program 17) Descent Orbit Initialization procedure.

PROGRADE (Program 20) Progrades the spacecraft, orienting the engine with the direction of travel. This is useful for increasing orbital velocity.

RETROGRADE (Program 21) Retrogrades the spacecraft, orienting the engine against the direction of travel. This is useful for reducing orbital velocity.

NORMAL PLUS (Program 22) Sets the spacecraft pointing to the perpendicular of the orbital plane. Useful for changing orbital inclination.

KILLROT (Program 24) Cancels the spacecraft rotation.

HOVER (Program 25) Hovers the spacecraft horizontally relative to the ground.

LEVEL FLIGHT (Program 26) Orients the spacecraft parallel to the horizon.

RADIAL PLUS (Program 27) Orients the spacecraft with the engine perpendicular to the orbital path pointing to the center.

RADIAL MINUS (Program 28) Orients the spacecraft with the engine perpendicular to the orbital path pointing away from the center.

DOCK COPLANAR (Program 31) Orients the spacecraft with the correct docking orientation, regardless of its alignment.

DOCK POINT TO (Program 32) Orients the spacecraft towards the docking target.

EARTH DOCKING (Program 33) Transposes, rotates and translates the Command Module to perform a docking with the Lunar Module still attached to the S-IVB.

DOCK PROGRADE (Program 34) Orients the spacecraft along the relative velocity vector with the target spacecraft.

DOCK RETROGRADE (Program 35) Retrogrades, pointing the engine against the RELATIVE velocity to the docking target aircraft. Engine thrust will kill the relative velocity.

KILL RELVEL (Program 39) Reduces the spacecraft's relative velocity to the docking target to 0.

SPS BURN (Program 40) Performs a SPS engine burn. This requires further data entry the the DSKY  console with parameters obtained from the burn-PAD.

REENTRY (Program 41) Space Shuttle reentry for Kennedy Space Center.

HOVER (Program 42) Hovers teh spacecraft keeping a constant altitude and vertical velocity.

AUTOLAND (Program 45) Lands the spacecraft/aircraft in the designated airport in the HSI AIRP panel.

PO ALIGNMENT (Program 50) Aligns the inertial platform to the parking orbit reported inclination.

NORMAL MINUS (Program 58) Orients the spacecraft perpendicular to the orbital plane (Normal -). This is useful for changing orbital inclination.

POWERED DESCENT (Program 63) Fires the descent engine and reduces velocity up to the final 2000 feet P64 go-no-go landing gate.

FINAL REENTRY (Program 64) Final reentry for the Command Module.

REENTRY (Program 92) Deorbits the Space Shuttle until a vector state fit for reentry to Kennedy Space Center.

CIRCULARIZE TOP (Program 101) Circularizes the orbit to the altitude of the highest point.

CIRCULARIZE LOWER (Program 102) Circularizes the orbit to the altitude of the lowest point.

ALIGN PLANE (Program 103) Aligns the orbital plane (select target in ORBIT visualizer). The first step to a successful Hohmann Transfer Orbit is to have both orbits share the same orbital plane. To do so you need to perform a normal +/- burn at the points where the two orbit planes intersect. These are commonly referred to as the Ascending Node (AN) and Descending Node (DN).

ENGINE BURN (Program 104) Automated engine burn executing the orbital changes selected in the ORBIT visualizer.

Astronautics Forum / Apollo Launch Pad Bunker????
« on: December 15, 2017, 02:25:03 PM »
Interestingly , the famous 39b/a launchpads that we all  know , house an emergency bunker below  , to be used by the astronauts in the case of an emergency (  fire ?) on the launch pad.

Thanks to a sef of pulleys , and a zip line . the 3 astronauts would winch themselves down the 110 meters height , and throught a set of tunnels/blast doors,  lock themselves inside the bunker ,until the big explosion. Remember that a fully fuelled Saturn V has roughtly 1/7th of the explosive power of an Hiroshima-type fission nuclear bomb.

When the risk of explosion would ve been over ( either beacause It actually blew up ) or the fire been put off, the crew would have been recovered with an M113 Armour Troop Carrier .

Most astronauts practiced driving the M113 tracked vehicle , so they could get back to safety . Here is some shuttle-astronaut after his training drive.

Development news / 1.0.9 (Mobile)
« on: August 28, 2017, 10:36:31 AM »
hi Guys.

Some work-in-progress of the new 1.0.9 (universal ,i.e. for both Mobile and Desktop)

Please do note than in version 1.0.9 we ll start rolling out the new self-patcher system.That means that at any time (or every time you start the app ) the game will self-update with the latest missions, bug fixes ,etc..    this is gonna take quite a bit of coding , on the other hand , will be probbably the last physical Update required , as after then , we can add missions, features, etc... directly , with no further need to update (and hence me start beggin again for reviews, 5-stars and so ;) )

Also , the HTML Server/Broswer ( yep , the game has a mini-web-server inside to serve the menu-pages ! ) , has been updated, allowing nice colorfull menues,  and most importantly RESIZEABLES , (as when you do CTrl-mouse wheel in Chrome ) , to select the size  ,etc.. of the html menu pages.

A new -more showable GUI system ,icon-based is being created , at the same time we are fixing those anoying GUI bugs ,etc..

and much more . Stay tuned :).

General Discussion / New Version AVAILABLE (1.0.8 )

We have just released the latest ( 1.0.8 ) version for Space Simulator  (mobile ) for iOS.  Featuring lots of bug fixed , new -more intuitive - way to arrange IU  ,some Apollo 13 Scenarios , better custom mission designer, better autopilot control , etc.. etc. etc

As usual , we are fully deppendent on your ratings and reviews . Every time we upload a new version, we need you to re-write  a review , and re-rate the app with 5 (or more ;) ) stars. This way we can keep on going developing the sim  with new features ,etc.... 

Thanks ! .

Development news / New Docking MFD Window
« on: May 12, 2017, 11:10:04 AM »
here is the new -more visual  MFD Docking window . With analog bars showing relative, absolute speeds, and distance , the missing grid for the relative attitudes,  detection of no-docking target , and a better automated docking procedure. Out very soon in 1.0.8 MOBILE.

There are a number of docking scenarios to play in this game. Here is the general procedure for performing a rendezvous/docking with a target vehicle.

1. Open the "DOCK" panel.
2. Hit "DIRCT" (direct) to point your spacecraft at the target.
3. Throttle up to move towards the target. The AVEL (absolute velocity) will reduce.
4. Retrograde in preparation for the next maneuver.
5. As you approach the target, there will come a point when the AVEL will stop decreasing. From now on you will not get any closer to the target moving in this direction. Throttle up in retrograde position to brake relative to your target until the RVEL (relative velocity) is 0m/s.
6. "DIRCT" once again to the target and repeat the direct/retrograde process until you are close enough to the target to make the final maneuvers manually with the RCS engines.

This is a video of Gemini 6 approaching Gemini 7 using this method:

we have developed  a new way of lighjting the spacecraft's interiors.   Given the specifics of a very small windows, a very bright (or dark) exterior , a new lighting solution was needed to achieve photorealistic interiors. 

now we compute the total light that enters throught the window , and compute the average number of bounces until it lights the entire cockpit.  Sounds easy , but coding a shader that does that in a reasonable time is not that easy. :)

Cockpits look now something like this : (Please note the earth's luminosity bathing the interior as it enters from the windows.

Anyone would know which is the actual color reference of this ? Either in rgb/ or even better the  RAL  code
