Hamster of Doom

Awesome, thank you so much.

I feel foolish, but I'm at my wit's end. Convinced I'm missing something obvious. I foolishly started a solo strike force to take down Numina with a lvl22 MM, and once it gets to her, I can't even make a dent. However, on my mission tab, it will not give me the option to abandon the mission, nor will it provide that option if I talk to the contact (Mortimer Kal). Is there anyway to get out of this, or am I stuck and unable to get any other missions until this one is done?
