feasability of colonizing Mars in 10 (not so easy) steps

18.Dec.2024

Mars, Space / Cosmos / Kosmos / Galaxy / Galaxie / Weltall

most recently another “scientific” “nay sayer” video has been uploaded of those who THINK they patented truth itself (know everything, which is arrogance and blashphemy because only god and nobody are perfect) saying colonizing Mars is “too expensive” “not feasable” or other reasons

those reasons don’t matter, because if mankind would NEVER dreamed big and attempted “the impossible” mankind would still not even ride horses because riding horses is “scientifically impossible” or “very dangerous” or “too expensive” (says the wise old lady)

OF COURSE the first steps would be to

send robots to Moon build artificial underground or above ground radiation hardened shelters where humans and plants could survive unharmed
- if that went well
send robots to Mars build artificial underground or above ground radiation hardened shelters where humans and plants could survive unharmed
before terraforming Mars is possible: more research (Sabine! RESEARCH!) needs to be done how to install a gigantic “magnetic shield generator satellite” between sun and mars (on the lagrange point where gravity cancels out) (ChatGPT says it’s gonna be hard but theoretically possible)
- that is strong enough to shield ALL of Mars from sun’s radiation that is knocking off precious oxygen and water into space (yes the beautiful warm sun also can do some bad if a planet loses magnetic field, so please be careful with the magnetic field of earth or risk end of ALL life on earth)

plz play that video it’s epic 😀

These steps build a framework for establishing a Mars colony that can one day thrive independently, with Earth-Mars collaboration and learning taking center stage in the process.

ChatGPT: feasibility of an artificial magnetic shield for Mars

question: how many satellites would be required to orbit mars in 300km altitude to create a magnetic field significant enough to slow down sun’s particles knocking off water and oxygen molecules?

Creating an artificial magnetic field around Mars using satellites at a 300 km altitude is an ambitious concept aimed at protecting the planet from the solar wind, which strips away the atmosphere, including water and oxygen molecules. The goal here is to generate a field strong enough to deflect the solar wind particles, creating a protective shield around Mars.

Key Assumptions and Considerations:

Protecting Mars from Solar Wind: The magnetic field must be strong enough to deflect charged particles from the Sun, particularly solar wind (which is primarily composed of electrons and protons) and cosmic radiation, in order to prevent them from stripping away the atmosphere. This is the mechanism that protects Earth through its global magnetic field.
Mars’ Atmospheric Loss: Mars is losing its atmosphere primarily due to the stripping action of the solar wind. Without a magnetic shield, solar wind particles interact with Mars’ upper atmosphere, gradually ionizing and sweeping away lighter molecules like H₂O and O₂. Mars has a very weak intrinsic magnetic field, so it is vulnerable to this process.
Creating an Artificial Magnetosphere: The goal is to establish a global artificial magnetosphere around Mars. The magnetic field needs to be strong enough to create a barrier that reduces the direct impact of solar wind particles on the Martian atmosphere, especially at the upper atmosphere levels (roughly 100 km altitude and above).

Key Parameters to Consider:

Strength of the Magnetic Field:
- The Earth’s magnetic field strength at the surface is around 25–65 µT (microteslas), but the field intensity near Earth’s magnetic poles can be much stronger. To effectively protect Mars from solar wind, a field of similar strength or greater would be needed at a radius of about 300 km altitude.
- The magnetic field strength required would need to be strong enough to create a protective magnetosphere. For comparison, Earth’s magnetosphere is extremely effective because of its dipole magnetic field and field strength on the order of 25 µT to 65 µT at the surface.
Altitude of the Satellites:
- The satellites will be placed at 300 km altitude above Mars’ surface. This means they will be well within Mars’ thin atmosphere, but high enough to minimize atmospheric drag and other perturbations.
Satellites’ Role:
- Each satellite would generate a local magnetic field, and the goal is for these fields to combine and overlap in a way that creates a global magnetic shield around the planet.
- The magnetic field generated by each satellite would fall off with the cube of the distance, so multiple satellites in orbit would be necessary to achieve global coverage.

Estimating the Number of Satellites

To estimate the number of satellites required, we need to consider several factors:

Magnetic Field Strength at 300 km Altitude:
- As mentioned earlier, we want to create a field at least as strong as Earth’s magnetic field, which is typically in the range of 25 µT to 65 µT.
- To generate a dipole magnetic field (similar to Earth’s), the strength of the field at a certain distance from the satellite depends on the magnetic moment of the satellite and the distance from it. This fall-off is proportional to $1/r31/r^3$ , where $rr$ is the distance from the satellite.
Area to be Covered:
- The goal is to cover a magnetospheric region around Mars, roughly from the surface of Mars (3,396 km radius) up to 5 Mars radii (16,980 km), with the protective field extending across a spherical shell of this radius.
- We need to ensure that the magnetic fields generated by satellites in low Mars orbit (300 km) can overlap and provide coverage over this region.
Calculating the Number of Satellites:
- Assume each satellite generates a local magnetic field strong enough to contribute to the global shield. The magnetic field from each satellite falls off as $1/r31/r^3$ , and to ensure sufficient overlap, we would need many satellites distributed in orbits around Mars.
Let’s assume that the total area that needs to be protected is approximately the surface area of a sphere with a radius of 5 Mars radii (16,980 km). The surface area $AA$ of this sphere is given by:

$A=4πr2A = 4 \pi r^2$ where $rr$ is the radius of the shield (16,980 km):

$A=4π(16,980 km)2≈1.44×109 km2A = 4 \pi (16,980 \, \text{km})^2 \approx 1.44 \times 10^9 \, \text{km}^2$ Now, assuming that each satellite’s magnetic field can effectively cover a small fraction of this area, we need to estimate how many satellites are necessary. If we assume each satellite can effectively cover 1% of the area (this is a rough assumption based on the overlap of their magnetic fields), then:

$Number of Satellites≈1.44×109 km2Area covered per satellite\text{Number of Satellites} \approx \frac{1.44 \times 10^9 \, \text{km}^2}{\text{Area covered per satellite}}$ If each satellite can cover around 1% of the total area:

$Number of Satellites≈100 satellites\text{Number of Satellites} \approx 100 \, \text{satellites}$

4. Power Requirements:

Each satellite would need a significant amount of power to generate the required magnetic field. Based on similar calculations for artificial magnetospheres, each satellite could require anywhere from 1 MW to 10 MW of power, depending on the magnetic moment required and the efficiency of the system.

Assuming an average of 5 MW per satellite:

$Total Power=100×5 MW=500 MW\text{Total Power} = 100 \times 5 \, \text{MW} = 500 \, \text{MW}$

This would be the approximate power needed for the entire system.

5. Final Estimations:

Number of Satellites: Roughly 100 satellites placed in orbit around Mars at 300 km altitude would be required to create a strong enough artificial magnetic field to protect Mars from the solar wind and reduce the loss of water and oxygen molecules.
Total Power Required: Around 500 MW of power would be needed for these satellites.

Summary

Altitude: Satellites would be placed at 300 km altitude around Mars.
Number of Satellites: About 100 satellites would be needed to create an artificial magnetic field strong enough to shield Mars from solar wind and atmospheric stripping.
Power Requirements: The system would require a total of around 500 MW of power to operate these satellites.

This is a very high-level estimation and involves many simplifying assumptions. In reality, the number of satellites and the exact power needed could vary based on the engineering details of the system, the efficiency of the magnetic field generation, and other factors like orbital configuration and satellite interaction.
