The group had been waiting for a return flight since Jan.24, but bad weather and aircraft equipment problems delayed their departure from the Antarctic for nearly a week. They were invited by the Brazilian Navy to take a look at how Brazilian scientific research funds are being spent by polar-based researchers. They are expected to arrive in Rio late this afternoon after a stopover in Pelotas, Rio Grande do Sul (Brazil).
The odds now is that they will no longer miss their Carnival celebrations in sunny Rio, or anywhere else in Brazil, after a weeks' down time under freezing polar temperatures. It's Brazil's down time to sweat out a cold now.
