Discussion Overview

The discussion revolves around the feasibility of creating a DIY moon probe on a small budget. Participants explore various concepts related to rocket design, launch methods, and cost considerations, addressing both theoretical and practical aspects of space exploration.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant proposes the idea of a small rocket capable of delivering a baseball-sized probe to the moon, suggesting it could use a pre-programmed landing routine and small thrusters.
  • Another participant argues that a budget of around fifty million dollars might be considered small in the context of lunar missions, while less than a million would be insufficient.
  • A suggestion is made to use a balloon to lift a rocket to high altitudes before launch, with an estimated cost of under $10,000.
  • Concerns are raised about the feasibility of achieving orbit and lunar trajectories, with one participant noting that a 4-stage liquid-fueled rocket would be required to get even a small payload into orbit.
  • Another participant emphasizes that designing a sounding rocket for $10,000 would be challenging, and that costs for viable lunar missions would likely be in the tens to hundreds of millions of dollars.

Areas of Agreement / Disagreement

Participants express differing views on what constitutes a "small budget" and the feasibility of launching a moon probe within that budget. There is no consensus on the practicality of the proposed methods or the associated costs.

Contextual Notes

Participants mention various assumptions regarding budget definitions, rocket design complexities, and the challenges of reaching orbit and lunar destinations. Specific mathematical and technical details are not fully resolved.

With a small budget would it be possible to make a rocket capable of delivering a small probe to the moon?

A rocket that puts the probe into Earth orbit and them Hoffman transfer to the moon and guides itself to the surface?

I am talking very small, maybe the size of a baseball, that transmits back to Earth and uses a pre-programmed landing routine with smallish thrusters.

Would it be possible?

If by a small budget you mean only fifty million dollars or so, then yes, it's possible. That is an incredibly small figure. None of the serious contenders in the Google Lunar X Prize contest expect the $30 million award (if they win it) to offset the costs. If your definition of small is less than a million, then no, it's not possible.
 
But what about a balloon that takes a rocket up to a very high altitude and then fires the rocket away from earth?

Should be less than $10k

The rocket will go up a little bit, and then fall back to Earth. Quiz question -- why?
 
You might investigate the minimum it would take to get, say 1 kg into Earth orbit before you worry about going to the Moon.

I did this a few years ago and came up with a 4-stage liquid fueled rocket weighing 3300 kg, about 11 m long, with a first stage thrust of about 40000 Newtons. Non-trivial.
 
Honestly, for $10k, you'd be hard pressed to even design a sounding rocket that could make it into space (>100km altitude). Orbit is significantly harder, and a lunar trajectory is harder still. I would expect any viable attempt to cost tens to hundreds of millions of dollars, even with a pretty small payload.
