The new version of scenarios looks very good. I like the voice acting and the clearer structure of the scenarios.
One suggestion though:
It would be great if a third answer/option was added to the distress signal sources - ahem scenario

- that would tell the ship in distress that the CMDR will help, but has to fetch the required things. The scenario would then stay active for a longer time.
For example the food scenario:
The player drops into source the distress call.
NPC asks for food.
Player has no food, but wants to deliver food.
The next station with food is one or two jumps away. Fetching food takes time.
A third answer "Wait please, I will bring you food" is offered. This will keep the scenario open for 30 minutes (maybe longer, maybe shorter - enough time to get the required things).
The player then can collect the required items and come back to help.
In the stream the time those USSs stay active seemed to be 5 minutes or so - that is not long enough to jump to an other system, dock at a station, buy stuff, undock, fly back to the USS.
Other than that the scenarios look like a really good enhancement of the game.
