If you haven't used your sampling system since you left Earth, be sure to rinse and spit Mars soil samples at least three times before beginning any experiments.
Mars is cold, dry and rocky. Extra moisturizer and sturdy shoes would be a good idea, plus oxygen for those of you who breathe.
Wish you weighed less? Visit the Red Planet. Because Mars is so much smaller, its gravity makes you weigh only 3/8 what you do on Earth.
