Markus and I are going to help prepare a new MIV for launch to intercept this "Comet Lovejoy" and claim it's alcohol and sugar for use in the Cloud Ark. We will need to reuse and tow the reactor from ymir, along with a full compliment of robots to handle all of the slave labor needed to adjust the orbit of this hunk of ice towards the Sun-Earth L1 la grange point. From there we use the alcohol to power the boosters around Old Earth into a high orbit towards Izzy. We can correct for everything bad that happens on the far side of the burn. Then it's 5,000 years old alcohol powered goodness.
Live long, Dr. Doob.
