The path is blocked. You have no choice but to turn back. I've plotted another route for you. It will be necessary to backtrack to the aft hangar bay and use one of the shuttlecraft. You can pilot it to the front of the ship and dock with fore starboard boarding hatch #2.
Your suit will protect you from vacuum for small amounts of time if necessary, but your air supply will only last a few minutes before needing to be recharged.
I do not recommend that you use your firearms in vacuum except in extreme situations. They are not designed for the environment. Accuracy is greatly reduced and they are likely to jam at very inopportune times. Use the alien plasma weapons whenever possible.
I have not determined how to recharge the alien weapons. Even if I did, it is unlikely our weakened power grid could provide the necessary wattage. Discard the alien weapons when they are depleted.
One final word of warning, if you are thrown from the hangar bay into open space, there will be no way to rescue you. Be careful.
