The route to Mars may go through Costa Rica. On Wednesday, Ronald Chang, executive director of Ad Astra Rocket Company Costa Rica, gave a presentation at the National Museum that detailed how Costa Rica has the opportunity to serve as a vital cog in the first-ever mission to Mars.

Chang is the brother of former NASA astronaut Dr. Franklin Chang, who in 24 years as an astronaut, logged over 1,600 hours in space during seven space missions, making him one of the most-traveled astronauts in history. Both of the Chang brothers were born in San José.

In his presentation, Ronald Chang explained that his brother created an ion plasma rocket, the Variable Specific Impulse Magnetoplasma Rocket, known as VASIMR, which can reach Mars in 39 days. Using technology currently available, a rocket can travel to Mars in eight to nine months.
