Discussion Overview

The discussion focuses on the challenges associated with sending humans to the Moon and Mars, exploring various aspects such as launch speed, direction, fuel requirements, and landing techniques. Participants express interest in both the technical and logistical considerations for these missions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant asks about the specific challenges for human missions to the Moon and Mars, including launch speed, direction, fuel usage, and landing methods.
  • Another participant suggests that the question is broad and recommends reviewing existing literature, such as the Apollo program, for more detailed information.
  • A third participant shares a link to a NASA document that outlines considerations for lunar missions, indicating the complexity involved even in uncrewed missions.
  • A later post reiterates the initial questions and emphasizes that the mission's purpose (short stay versus long-term base) significantly influences the requirements for resources like oxygen, water, and energy.
  • This participant also notes that the Space Shuttle is not suitable for Moon and Mars missions, mentioning NASA's development of the Crew Exploration Vehicle (CEV) and a cargo vehicle for these missions.
  • Additionally, the idea of a Mars Orbital Station is proposed to support surface facilities, highlighting the challenges of transporting large objects to both the Moon and Mars.

Areas of Agreement / Disagreement

Participants express a range of views on the challenges of lunar and Martian missions, with no consensus reached on specific solutions or approaches. The discussion remains open-ended with multiple competing perspectives on the technical requirements and mission planning.

Contextual Notes

Participants have not fully defined the assumptions underlying their questions, and there is a lack of detailed exploration of the mathematical and technical steps involved in the proposed missions.

Based on my title, I have the following questions:

1) What are all the challenges for man to go on the moon?

2) What are all the challenges for man to go on the Mars planet?

I am mostly interested in what speed, what direction the shuttle is launched at? How much fuel is used in this? What velocity is it traveling at various point of the journey? How does it actually land on the moon and mars?

That's an extremely broad question. You could start by reading the Wik entry on the Apollo program, then come back with specific questions...

The answer dependent on the purpose of the mission - short stay like Apollo or beginning a long term occupied base, which requires considerable resources. A lunar and Martian base will require oxygen, water and energy.

How many people?

Also, a shuttle will not do. The Shuttle is for near Earth orbit.

For Moon and Mars, NASA is developing the Crew Exploration Vehicle (CEV), which is a larger variant of the Apollo capsule. That will be supplemented with a cargo vehicle, and both will use a Shuttle-derived booster system.

For Mars, I'd add a Skylab/ISS type of Mars Orbital Station to supplement a surface facility. Putting large objects on Mars (and even the Moon) will be challenging.
