He said, “Today, we are on the cusp of amazing discoveries that could tell us more about the possibility of life outside Earth,” in statement. Bridenstein explained that astrobiology, which includes the search for life elsewhere, is a major priority at NASA.
Bridenstein is cited New search An international team of astronomers revealed the discovery of a rare molecule, phosphine, in the clouds of Venus.
Scientists note that on Earth, the gas is only synthesized artificially or by microbes that thrive in oxygen-free environments.
Bridenstine described the finding as “interesting,” indicating that it could indicate biometrics. He said, “As is usual in science, the more we learn, the more questions we have.” “This is the virtuous cycle of discovery, including the discovery of potential biomarkers in other worlds.”
The NASA chief explained that four missions are being considered for up to two discovery missions that will be scheduled in 2021. “Among them is an astrobiology mission to Neptune Triton and a geological mission to the most volcanically active planet in the solar system, Jupiter’s moon Io,” he said. The other two missions under consideration have proposed missions to Venus. One focuses on understanding its atmosphere and the other on understanding the geological history of Venus. “
NASA is also partnering with Europe on another proposed Venus mission called EnVision, according to Bridenstine.
