It uses a terrier engine, and ive gotten it off the mun, but I'm not sure if it can get off Duna. It doesn't have to get back to kerbin, just to a low Duna orbit to dock back with an orbiting crew spacecraft.

Rest in peace my supply mission. At least Bill is happy.

What did I do wrong

But unfortunately, our beloved Kerbel passed away while trying to return to the earth. Rest in peace.

I completed a contract to haul a heavy engine and wanted to see if the parachutes would save it. The craft was travelling too fast and was headed for destruction until it suddenly flew up Buzz Lightyear style allowing me to deploy the chutes and recover.
