Since the issuance of U.S. President Barack Obama’s National Space Policy on June 28, the administration has left in place, for now, the George W. Bush administration’s targeted policies on space transportation, remote sensing, and positioning, navigation, and timing. Revision of these policies is expected to begin in the next year. In contrast, the previous administration’s space exploration policy was rescinded, but there is no indication that a replacement is forthcoming. This would leave a serious gap because the language on this topic in the National Space Policy is insufficient to guide NASA’s flagship activity through the decades ahead.
