NASA Innovative Advanced Concepts (NIAC) had their 2016 symposium on August 23-25, 2016.
There is an update on the Topor induced state for long duration space trip to places like Mars.
This is from 30:00 to 63:00
The Topor state can reduce the crew consumables by about half and the ship could 40-70% smaller.
With enough compaction of the crew space capsule it could be possible to go to Mars in a non-Holmann transfer orbit.
