Elon Musk predicts that humans will land on Mars for the first time within 5 years!

1. At the fastest in 5 years, humans can complete the first crewed landing on Mars, ushering in the Mars era
2. Getting to Mars is hard!
Earth to Mars is over one hundred million kilometers, so it needs the right position to travel there using an elliptical orbit; there’s only an opportunity every 26 months, and the one-way trip takes 6–9 months
3. Large-scale Mars colonization in the next 10–12 years
With the advancement of spacecraft technology, after that, every 26 months, large quantities of supplies will be sent over—making Mars a new home!
