Did they make sure there were minutes left on Parker's SIM card?

At 430,000 mph, it could make a trip from Earth to Mars in under 4 days. It makes you realize that if there is any "barrier" for humans to make a trip to Mars, it probably the speed of the spacecraft.

Think of the time and the distance of the acceleration to reach that velocity.

No, the limit is the endurance of the human body in the conditions produced by the trip. How do you get to 400,000 mph?

Start with our current speed to the Moon at 5,000 mph and start improving on it. A point of the article is that a spacecraft made it to a speed that would easily overcome the distance to Mars. It invites us to think about improving our speed for voyages in the solar system.
