Question revisited

I asked because I run a model rocket group. Just for fun I proposed launching on the moon. Model rocket engines use a solid propellant with an oxidizer.

The moon is surrounded by the vacuum of space, the perfect insulator on earth. Does this mean the only heat loss experienced by the model would be mainly radiant?

    - yes. - ER - 7/22/2022 5:12:36 PM
      - The cool thing is, modern high power model rockets can easily reach lunar escape velocity. - RobVG - 7/23/2022 10:15:29 PM
        
        Why not launch one from a high altitude balloon? - ER - 7/24/2022 12:30:35 AM
        
        It was done in 1997. - RobVG - 7/28/2022 1:04:03 AM
        
        Air density would probably be an issue. - RobVG - 7/24/2022 7:58:41 PM
        
        How about big fins for the thin air. - ER - 7/25/2022 12:35:34 AM
        
        That's a possibility. Fall away boosters with larger fins are commonplace. - RobVG - 7/25/2022 2:49:35 AM
        
        Good idea! - RobVG - 7/24/2022 1:59:53 AM
      - Great answer. Thanks again ER. - RobVG - 7/23/2022 3:02:25 AM
  - Thanks. it was one of those bedtime thoughts. - RobVG - 7/16/2022 4:54:35 PM
