[Can't slow down fast enaugh when reentering kerbin]

Thank you very much. It worked pretty well. Finally landed it.

[Can't slow down fast enaugh when reentering kerbin]

I am already in orbit and I can't go back to lunch. I can't reenter kerbin because I think my ship is too heavy. It either overheats and explode or it doesn't slow down fast enough so I can't open my parachute. I didn't put and heatshields. I tried to set the periapsis to 40k,35k,20k,10k I even tried 0k but nothing works. How can I save my astronauts?http://imgur.com/zc9w5Wn
