Recently, NASA announced that they are doing a research, trying to figure out why Mars is a lifeless and dead planet. According to the announcement, our Sun and solar winds is the main reason why it doesn’t have an atmosphere. This is an ongoing process for Mars and these results are important for us to understand the history and evolution of Mars. The findings came from researchers from the US space agency’s Maven, orbiting Mars.
The air pressure on Mars is less than 1% of what we have here, on Earth. Once warm and wet, Mars had lakes and maybe even oceans, but now it is a cold and harsh planet. Solar storms are not everyday events, but they are not rare either. Changes that happened on Mars are the result of solar winds and solar storms were stronger in earlier Solar System history.
The principal investigator on NASA’s Maven spacecraft, Bruce Jakosky stated: “We’re still analyzing this data, and we have already been approved for a mission extension that will allow us to round out one full Martian year and to see the response of the system to all the seasons on Mars.”
Why didn’t solar winds damage our atmosphere? Luckily, Earth has a global magnetic field that protects our planet from strong solar winds.
