It is shown that space-based gravitational-wave detectors such as DECIGO and/or the Big Bang Observer will provide us with invaluable information on the cosmic thermal history after inflation, and they will be able to determine the reheat temperature T{sub R} provided that it lies in the range preferred by the cosmological gravitino problem, T{sub R}{approx}10{sup 5-9} GeV. Therefore it is strongly desired that they will be put into practice as soon as possible.
