Okay, working this one through: In theory it's possible to survive and stay conscious for a short time in space, maybe 30 seconds? So you'd have to somehow smash the glass and propel yourself towards the hatch, and if you were quick enough you'd survive. The steel rod and outside of the glass would presumably be too hot or cold to safely touch. I can't think of an answer that uses everything given in the riddle, so I'll make a joke answer: After procrastinating for ages you decide it's now or never so, heart in your mouth, you smash the glass with a club. You then throw big spades away from the ship, propelling you towards it while you watch the diamonds in the sky. After entering the hatch, you close the airlock and say "Ha! I am the King/Queen of space! I Aced that! Oops, I forgot Jack the rodent..."
