You will not be able to consolidate your old, defaulted loan in with a new loan because if you are in default you cannot be awarded a new loan.
Most students have more than one student loan even if they only went to school for one year (usually a subsidized and an unsubsidized loan). If that's the case, you can proceed with a consolidation without having to add in a new loan. If you don't have two loans, you cannot consolidate, but you can get out of default by either paying off the loan or making 9 consecutive on-time payments. You actually become eligible for aid again after you have made six payments, so you may be able to start again for a late spring or summer session. Keep in mind that if you will have to keep paying in order to continue to receive financial aid, so if you're not in the position to do that, there's not much sense in taking on more loans.
If you are going to go the route of making the 9 payments, make sure you send them a least a week before they are due, and don't depend on any grace periods. If your payment is received even one day late, you have to start the process all over again, so give yourself plenty of lead time.
