Brazilian Space Program for Orbiter v2 is released!

Brazilian Space Program for Orbiter v2, including the Alcantara Launch Center (CLA) , the VLS-1 satellite launcher (Veículo Lançador de Satélites), the VLM-1 microsatellite launcher (Veículo Lançador de Microssatélites), a Microsatellite, the VS-40 sounding rocket and the SARA reentry experiment .





Current version release notes:
  • Improved VLS detailed mesh and textures, now using normal maps for high resolution light effects on the latest graphic clients for Orbiter.
     
  • Improved textures with normal maps for the VLM-1, VS-40 and SARA.
     
  • Expanded the Alcântara Base, that now features details such as trees, terrain and various structures. Instead of adding new surface bases to Orbiter, this implementation builds upon my “Stock Orbiter default bases upgrade” add-on, only replacing (and improving upon) the Alcantara one.
    Notice: please remove the Alcantara_CLA.cfg and Base_de_Alcantara.cfg base config files from your Orbiter installation, if installing over the previous version.
     
  • Improved launch autopilot for the VLS-1 satellite launcher, which is now able to induce a stabilization roll to the upper stage, previous to the final burn.
     
  • Notice that the last stage on both VLS-1 and VLM-1 rockets is designed for a delayed burn (more than 200sec) and has no attitude control system (only spin stabilized). So be patient and let the guidance run until all fuel is spent.
     
  • To give some replay value, the autopilot will not place the satellite in a circular orbit. The guidance program provided is only meant to provide a reference to the intended launch profile and timings. It’s your job to launch manually or by autopilot to whatever orbit you desire.
     
  • New VS-40 rocket. This is a sounding rocket from the same family of the VLS-1, using the same solid rocket engines. I’ve programmed accurate flight behavior in LUA, including roll induced by the tail fins and launch from a dedicated tower.
     
  • New SARA reentry experiment, using both the VS-40 and VLS-1 rockets for suborbital and orbital flights. Aerodynamic parameters for reentry are “beta”, but usable.
