![]() It's not going to be much good for anything else Juno is going to be exposed to a huge amount of radiation which will degrade its instruments, power systems, computers and support hardware.Its solar panels won't produce enough power if you get much further away from the sun Its instruments are designed for a specific mission profile, if you sent it elsewhere it wouldn't be able to produce good science.You can't re-purpose Juno after its mission as: Additional attendees included representatives from the European Space Agency, the French space agency (CNES), and the German space agency (DLR). This workshop was instigated in part by NASA, was chaired by NASA's previous planetary protection officer, and attended by NASA's current planetary protection officer. Inherent in the conduct of scientific, exploration, and other activities-whether by robotic or human missions-is the need to consider and appropriately protect potential extraterrestrial life. To this end, the COSPAR (Committee on Space Research) Planetary Protection Policy subcommittee held a workshop in 2010 on " Ethical Considerations for Planetary Protection in Space Exploration." One of the key recommendations from this workshop was to bolster COSPAR's Planetary Protection Policy with a statement that In addition the scientific concerns cited above, there are even stronger ethical concerns regarding contaminating other solar system bodies with Earth-borne life. Avoiding the biological contamination of explored environments that may obscure our ability to find life elsewhere – if it exists.Preserving our ability to study other worlds as they exist in their natural states and.NASA has an Office of Planetary Protection. Shall pursue studies of outer space, including the moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment of the earth resulting from the introduction of extraterrestrial matter and, where necessary, shall adopt appropriate measures for this purpose. Article IX of "Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies" (aka the Outer Space Treaty, to which the US and every other space-faring nation are parties) says that parties to the treaty The concept of planetary protection is ensconced in international treaty. The spacecraft was purposely put on a collision course with Jupiter because the onboard propellant was nearly depleted and to eliminate any chance of an unwanted impact between the spacecraft and Jupiter's moon Europa, which Galileo discovered is likely to have a subsurface ocean. To this end, thirteen years ago, the Galileo probe met the same fiery death that Juno will one day meet: ![]() If that moon already bears life of its own, no matter how primitive, our dead and useless satellite may have spread the seeds that eventually kill that life. Suppose the dead spacecraft collides with one of Jupiter's moons, and in the process contaminates that moon with Earth-borne life. It's because life might well exist on some of Jupiter's moons.ĭespite the best efforts to assemble the spacecraft in extremely clean conditions, and despite exposing the spacecraft to vacuum and to the Sun's ultraviolet and X-ray radiation, there's a chance that Earth-borne life remains intact on the satellite. Why is it necessary to destroy the spacecraft?
