Curiosity is NASA's most digitally savvy rover yet. She tweets regularly, posts her pictures and now she is the first Foursquare user to ever check in on Mars.

Curiosity's first check-in was today at the Gale Crater, where she made her first landing on the night of Aug. 5. Located on the equator of Mars, the Gale Crater is home to the 3-mile high Mount Sharp and is Curiosity's primary target as it holds billions of years of Martian history.

Curiosity will continue to check in and share updates throughout her 23-month expedition.

"Like any great trip, you want to share with your friends back home, so that is why the rover is sharing check-ins and tips from her amazing trip," says Stephanie L. Smith, who is part of the three-woman team that runs Curiosity's social media.

Since Curiosity is the first to post from the Red Planet, she will regularly give travel tips for future space tourists.

"Mars is cold, dry and rocky. Extra moisturizer and sturdy shoes would be a good idea, plus oxygen for those of you who breathe," she posted along with a snapshot of the desert-like landscape.

Curiosity's next check-in will be from Rocknest, another point within the Gale Crater where the rover will be parked for the next two weeks to conduct various experiments.

"We'll start getting to more specific locations within the crater," says Veronica McGregor, social media manager at NASA. "We may not do daily check-ins for each drive, but we will be able to do check-ins and tips for locations after we name them."

Curiosity's Foursquare tips will be a mix of science and humor. "We're having fun with these tips," says NASA social media specialist Courtney O'Connor. "We have to consider things like atmosphere, temperature and things we don't normally think about on Earth. We have to put ourselves into her point of view. You have to get into character."

So far, the rover has checked in two times today. She only has one more check-in until she becomes mayor of Gale Crater — an honor that, McGregor says, is well-deserved.

"If anyone should be mayor, it's that rover."
