Bro there is no such thing. There is no person who's died in space whose remains were never recovered. No such thing as a solar-orbit human remains. I don't know where you got that idea, but a [citation needed] looms over your comment from here on in.
"The Judica-Cordiglia recordings are widely dismissed as forgeries these days. In his biography, Gagarin suggested that most of the lost cosmonaut theories could be explained by accidents that happened in low orbit, not actually in space.
Even in declassified Soviet documents about the space program, there’s no mention of any missing cosmonauts. So, most of the evidence suggests that the story of the lost cosmonauts is probably just another of the many myths of the Cold War."
Thanks for the correction. (Could be a tad more diplomatic I suppose)
