How difficult is it for humans to land on Mars?
With the continuous investment in Mars exploration by institutions such as SpaceX and NASA, the dream of human beings to land on Mars seems to be getting closer and closer to reality. However, behind this feat is a huge technical challenge. This article will analyze the technical difficulty of landing on Mars from multiple dimensions, and combine the hot topics in the past 10 days to explore whether current technology can support this goal.
1. Key technical challenges of Mars mission
The distance between Mars and the Earth, the environmental differences and mission complexity make landing on Mars one of the most difficult tasks in human space history. The following are the main technical difficulties:
| Technical field | Specific challenges | Current progress |
|---|---|---|
| Propulsion system | Need efficient propellants and long-term space navigation capabilities | Reliability has not been verified in SpaceX Starship Test |
| Life maintenance | Need to maintain a closed circulation system for 2-3 years | The International Space Station has been partially verified, but is insufficient in scale |
| Landing technology | Mars' atmosphere is thin and it's difficult to slow down | Perseverance landed successfully, but manned landing is even more difficult |
| Radiation protection | Deep space radiation dose is 100 times that of Earth | No mature solution yet |
2. Recent hot spots: technological breakthroughs and controversies
In the past 10 days, the popular discussions about Mars exploration have focused on the following directions:
| Hot Topics | Core content | Related parties |
|---|---|---|
| SpaceX Starship's third test flight | Realize space flight but fail to reentry | Musk says "major progress" |
| NASA Budget Dispute | Mars-related budget may be reduced in 2025 | U.S. Congress is under discussion |
| New discoveries of China's Mars rover | Zhurong found evidence of liquid water activity | Science magazine reported |
| Breakthrough in artificial gravity research | Progress in rotary cabin experiment | Japan JAXA releases |
3. Timeline and cost analysis
According to the plans announced by space agencies in various countries, the timetable and estimated costs of manned Mars missions are as follows:
| Institution/Company | Plan time | Estimated cost | Main technical paths |
|---|---|---|---|
| NASA | The late 2030s | About $100 billion | SLS Rockets + Deep Space Portal |
| SpaceX | 2029 (Target) | Undisclosed (estimated tens of billions) | Starship system |
| China Aerospace | Around 2040 | Not disclosed | Long March Nine+combination mission |
4. Physiological and psychological challenges that cannot be ignored
In addition to engineering and technical difficulties, astronauts' physiological adaptation and psychological tolerance are equally critical:
1.Muscle atrophy: Muscle mass decreases by 1-2% per month in long-term weightless environments
2.Bone loss: The monthly loss of space is equivalent to that of the elderly on Earth for one year
3.Psychological stress: Closed environment may cause psychological problems such as depression
4.Circadian rhythm: Mars sun is about 40 minutes longer than Earth, and you need to adapt again
5. Conclusion: How long will it take to cross the technical gap?
Based on the current technical level and the latest research progress, humans still face many challenges when landing on Mars. It is optimistic that this goal may be achieved by the end of the 2030s at the earliest, but core technical problems such as system reliability, radiation protection, and life support need to be solved. Recent SpaceX testing and the discovery of China's Mars rover have injected new impetus into this goal, but there is still a long way to go before a truly manned landing.
It is worth noting that with the addition of commercial aerospace companies, the traditional aerospace pattern is being broken. In the next 10 years, we may witness more breakthrough progress, but we must also maintain a scientific and prudent attitude and recognize that this is a systematic project that requires global cooperation and long-term investment.
