In a conceptual study in 2005, the agency commissioned Promessa, a Swedish company that specializes in organic burial solutions, to advise on engineering spatially economic astro-coffins. The result was the Body Back, which is essentially a vibrating Gore-Tex sleeping bag for the deceased.<br /><br /><br />The Body Back makes use of a process called promession, an ecologically friendly method of burial developed by biologist Susanne Wiigh-Mäsak, who founded Promessa in 2001 to capitalize on her idea. The promession process was slightly modified for the Body Back to meet the requirements of space travel, but the core ideas remain the same: First, a body is placed in an airtight bag and exposed to the freezing temperatures of space. (On Earth, this freezing is accomplished by placing the body in liquid nitrogen at a temperature of about minus 200 degrees Celsius.) After about an hour, the now-frozen body is brought back into the cabin from the airlock and vibrated at a high frequency, effectively shattering it and reducing it to a fine powder. Subsequently the powder is dehydrated, resulting in roughly 50 pounds of body dust. This dust is then stored in a container outside the craft until it is time to re-enter Earth’s atmosphere, at which point it would be retrieved and stored in the cabin for the few minutes it takes to descend to the Earth’s surface from space.<br /><br /><br />Wiigh-Mäsak says she believes the Body Back could conceivably be aboard missions for Mars in the next few decades, although there is quite a bit of fine-tuning to be done before it goes orbital. “It was [NASA’s] task to come up with suggestions for adopting [promession for space], and they never went that deep into details,” she told me. “If and when it becomes a reality, we will have to go into the details together with a team of engineers. There will be a number of challenges to solve, I am sure.”"<br /><br />SensemakerAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-37147210.post-1692556755328521152014-02-07T13:15:52.844+01:002014-02-07T13:15:52.844+01:00Även om den fungerade perfekt kan man fråga sig if...Även om den fungerade perfekt kan man fråga sig ifall den egentligen ger någon miljövinst. Att nedfrysa 70 kg människa till minus 196 grader och sedan frystorka detta torde tarva en hel del energi. Mer än att bränna kroppen kanske. Är själva kroppens "miljöskada" ens särskilt relevant jämfört med den (förmodar jag) mycket större miljöskada som uppkommer när släktingar reser (kanske mest med flyg och bil) till begravningen?<br /><br />Kanske är det bästa sättet att skapa en miljövänlig begravning att be att ingen av de sörjande gör en lång resa med miljöskadliga transportmedel för att bevista begravningen.<br /><br />SensemakerAnonymousnoreply@blogger.com
