NASA quietly hunting for ETs in LEO and the moon (and maybe Earth)
Sorry. No URL for this newsletter. If you want to sign up for it yourself goto https://thedebrief.org. ~ ~ ~ ~ Technosignatures, Telescopes, and Life on Mars Micah Hanks Apr 15, 2021 12:20 pm The Intelligence Debrief Technosignatures Welcome to your weekly Intelligence Brief. In our roundup this time are 1) software updates being sent to NASA's robots on Mars, 2) how some scientists are proposing novel ways of searching for evidence of intelligent extraterrestrials, and 3) why the telescopes of tomorrow may be gamechangers in the search for extraterrestrial intelligence. ... Other Signs of Life: Technosignatures and Space Wreckage Although Perseverance's mission may be among the most ambitious efforts to find evidence of life on other worlds currently underway, sending robotic probes to find evidence of past or present microbial life is only one method scientists have proposed for finding evidence of extraterrestrials. Other possibilities that have been proposed in recent days involve searches for technological remnants of past intelligent civilizations, or even evidence of extraterrestrial activity that might currently detectable around nearby planets. A recent NASA-funded paper outlined a number of innovative strategies astronomers might begin to employ in the search for technosignatures of extraterrestrial civilizations, which even included scouring planets like Mars and Mercury, as well as the moons of these planets (and our own) for evidence of crashed probes or other technologies. Talking recently with Jacob Haqq-Misra, Senior Research Investigator at Blue Marble Space Institute of Science and one of the recent paper's coauthors, I asked him about whether searching for technosignatures on nearby planets-or even Earth's moon-seemed like a worthwhile idea. "We will not know until we look," Haqq Misra said, adding that among those who have advocated the idea had been his colleague Daniel Angerhausen, who presented a poster at TechnoClimes a while back "about his ongoing research to use machine learning to search for anomalies in high-resolution lunar surface data." "Mars is another good place to search for surface artifacts," Haqq-Misra says. "Likewise we could look in the asteroid belt for evidence of mining by extraterrestrial visitors." Other possible strategies include more traditional methods involving telescopes to conduct searches for extraterrestrial civilizations. However, with the advanced telescopes we can expect to see in the years ahead, it is also likely that there will be significant improvements in their ability to detect possible evidence of alien technologies. Technosignatures and the Telescopes of Tomorrow "The best telescopes being considered that could search for some technosignaturesare mission concepts that are currently being studied by NASA, such as LUVOIR and the Origins Space Telescope," Haqq-Misra told The Debrief. "ESA also has a mission concept known as LIFE that could search for technosignatures. Our paper describes ideal missions for technosignature-focused observations, but I doubt there will be a mission any time soon that is dedicated to searching for technosignatures." [image] James Webb TelescopeAn artist's rendition of the James Webb Telescope "The James Webb Telescope might be able to characterize the atmosphere of one or 2 nearby systems," Haqq Misra adds, "so this could be one of the first attempts to search for biosignatures and technosignatures. However, the best missions are the concepts currently under study like LUVOIR and Origins, which would not launch for about 20 years." Haqq Misra also told us that there are ways growth in the private sector could benefit astronmer's searches for technosignatures. As an example, he cited the Breakthrough Listen initiative as an example. "But even commercial space exploration could provide indirect benefits," Haqq Misra told The Debrief, "as the demand for a space-trained workforce will lead to more graduates in astronomy and planetary science, which could also help to increase overall awareness and interest in technosignature science." .... -- Upcoming events: "Online Haters" Are Psychopaths, Recent Study Finds.
