I guess that is one way to do it. It sounds like all of our landings (including the moon) were planned out from the very beginning.

It really is quite an amazing bit of planning and navigation. The probe, on a direct flight from Earth to Mars, is adjusted in its flight trajectory on its approach Mars, and without orbiting the planet, instead directly descends for a landing. The calculations are so good, they can then land exactly at the coordinates chosen for the mission.

The orbits of the Earth and Mars, the velocity of the ship, the rotation of Mars. That’s a lot of math to calculate hitting the designated landing.

LOL, in that light, I would hope all those robot-building geeks who make the robots for the “BattleBots” show would give their country a patriotic return on their investment!

GPS coordinates - useless unless you know how they’re geo-referenced here on earth.

I don’t know. Maybe JPL missed a great opportunity for Muslim outreach. Maybe the message should have been: “Allah Akbar!”

He also included the GPS coordinates for the mission's headquarters at the Jet Propulsion Laboratory in Pasadena, California.

I'm sure Martian High Command is delighted to know where to send their retaliatory strike.

A “War of The Worlds” scenario can no longer happen. The Martians would land in California but thanks to all of the diseases illegal aliens brought in, the germs and viruses would kill the Martians off before they could shoot their first death ray.

I just learned of the Friedmans last month. Whether they knew it or not, they and especially Elizebeth, were evidence of God’s favor and providence towards the USA.

Just to note...I do like that they did it. I enjoy things like that.

It’s just that I enjoy anthropomorphizing Martians.

They hate that.
