“ I really wish Earth . So any place trip I take , I ’m double checking that there ’s sufficient funds for me to return , " the astrophysicist said inthe AMA . " Also , I ’m not taking that trip until Elon Musk sends his Mother and wreak her back alert . Then I ’m dependable for it . ”

Going to Mars is not go to be a walk of life in the park . There are many peril alreadyestablishedand there are probably more uncertainness waiting to be discovered . With SpaceX preparation to get off people toMarspossibly as ahead of time as 2025 , Tyson ’s request of a return trip and mother - tested guard are actually quite sensible .

“ I ’m simultaneously one of Space - X ’s big critic and supporters . I ’ve said many time and many piazza , that labor that are hugely expensive and dangerous , with uncertain returns on investment make pitiful activities of net - driven company , ” Tysonadded . “ Governments do these things first , allowing private enterprise to learn what to do and what not to do , then come next with a plan that involves us all . So my read of story is that private fellowship will not be the first to send humans to Mars unless government actually pay   for it . ”

This AMA comes right after SpaceX ’s historiclaunch and landingof a reusable rocket and there was a bunch of hullabaloo in the thread about the company .

Tyson gloss : “ Any demonstration of roquette reusability is a good thing . When we fly on a Boeing 747 across not bad distances , we do n’t throw it aside and roll out a novel one . Reusability is arguably the most cardinal feature of affordable expensive things . ”

It was n’t just rocket science discussed in the thread , though . Tyson , who ’s the manager of the Hayden Planetarium , also talked about scientific literacy and teaching , stating that one of his career end is to foster an entire generation of scientist as educators .

He also answered some rather ghoulish question ( you may checkthe full threadhere ) . He has previously express the most interesting mode to die is falling into a black maw , so it ’s not surprising that he was asked what the 2nd most interesting way is .

“ peradventure a closeup purview of a Supernova explosion . One of the great event in the universe . Happens maybe only once per C per beetleweed , " heanswered . " It would reckon beautiful up close , right up until the energy vividness vaporized you . ”
