I've heard a lot about orbital debris in space. All Celestis launches comply with the Office of Commercial Space Transportation of the U.S. Federal Aviation Administration which licenses each mission after due consideration of these and other relevant issues. Celestis Earthview Service satellites will vaporize like a shooting star on reentry, creating no debris. The Voyager Service spacecraft will travel harmlessly and eternally through the vastness of space. The Lunar Service spacecraft may impact the Moon's barren surface, but extreme surface conditions on the Moon help to assure there is no contamination from Earth.
Most people realize that space flight is very complicated.
Fortunately, Celestis has not experienced any launch failures. If a Celestis launch fails, several options are available. For the Earthview, Lunar and Voyager Service, only a portion of cremated remains is aboard. A second portion is collected by Celestis as a normal part of our process in order to fly on a second launch if the first attempt fails. As set out in the Service Contract, Celestis does not get paid until we perform the service.
