We welcomed to Hotel Mars Pablo de Leon to discuss HSF capsules from Vostok to Dragon Rider. We discussed the capsule design, why we are still using them, how they were out of favor at one time and are now in favor, plus the future for capsules for human spaceflight.  We talked about the thrusters on the Soyuz plus what Dragon Rider is planning to use, plus electronics and computer advancements along with environmental advancements being used in the new capsules.  Pablo also discussed alternatives to capsules that we have attempted to develop over the years but without success.

During our 11 minute plus discussion, John, Pablo de Leon and I talked about the recent spacesuit helmet to flood with water and the associated risk for Astronaut Luca Parmitano.  We also discussed design and technical flaws with the American EVA spacesuit as it was not designed to be maintained and serviced in space but to be brought back to Earth using the shuttle.  In contrast, the Russian Orlan suit was designed for repairs and maintenance in space.  Pablo mentioned other differences as well with the American and Russian suits. For example, the Russian suit operates at a much higher pressure causing the user to tire more easily and quicker, plus the higher pressure limits some movements.  I asked Pablo about progress with the idea of the positive pressure suit but as you will hear, nothing on the near term. In fact, as our Hotel Mars segment ended, Pablo said we will be using existing suit technology and materials for at least ten more years before new materials, manufacturing processes, and concepts are able to being entering the market.
