 Ever wanted to be an astronaut? Imagine it was you, who was heading to the hot zone of the two inner planets, where would you go? What would you see? And how would you survive? The latest robotic machines have revealed more about these worlds than ever before. 


 
Armed with this new knowledge, think of this as your personal travel guide to our near neighbors.
 
 
 
As the planet closest to the sun, Mercury is the ultimate summer vacation.
 
 
 
Step out of your spacecraft and sizzling temperatures are guaranteed for a day that lasts three months. And when the sun finally does set, the night life begins with a unique cosmic light show. This is one pockmark planet worth taking a closer look at.
 
 
 
Like our moon, Mercury is covered in craters 2.
 
 
 
I mean, you can't look at the moon or Mercury without seeing impact craters.
 
 
 
It's a good thing \ Brett Denevi loves the big impact. As a member of the imaging team on the current Messenger mission to Mercury, she sees a lot of them.
 
 
 
What's exciting for me is likely to be one of the first people to see these images of, you know, places on the planet that we've never seen before.
 
 
 
Most people come here to meteor crater 1 in Arizona to see a big hole in the ground. Brett's desires run deeper.
 
 
 
If you wanna study impact craters on Mercury, this is the best place to come. I mean this is the most well-preserved impact crater on earth. It's the closest you're going to get.
 
 
 
Wonder what it would be like to take a stroll on Mercury? You can walk around meteor crater in about an hour. But on mercury, you wouldn't know when to stop.
