The first image of Earth taken from outer space
- zeteo 4y agoHere's a short newsreel from the time that includes the flight footage: https://www.youtube.com/watch?v=Sykfqa3MKAg https://www.youtube.com/watch?v=Sykfqa3MKAg
- throwawayboise 4y agoI don't think a 65 miles suborbital flight qualifies as "outer space" but still cool to see.
- bagels 4y agoIt's a widely used definition of the boundary of space. https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line
- throwawayboise 4y agoInteresting. I always thought outer space was at least beyond the lunar orbit.
- mb7733 4y agoWhat would the area between the edge of the atmosphere and lunar orbit be called then?
- naavis 4y agoWhy does it need a name?
- pgreenwood 4y agoThat would be called cislunar space.
- TheRealNGenius 4y agoBy this metric, the ISS is clearly not in outer space then. Nor any satellites. Seems like parent threw their sense of logic to boise as well.
- dotancohen 4y agoI believe that the adjective "outer" is superfluous and does not change the meaning of the sentence. "Outer space" is synonymous with "space", which by the generally accepted definition begins at 100 km altitude (about 62 miles).
- midasuni 4y agoSure, but the term “outer space” suggests an area beyond “space” Where is “inner space” or “middle space”?
- martyvis 4y agoYeah it has always sounded a bit weird. I guess "space" is considered the world we can experience by conventional means and specifically we can survive in it with minimal support, that is we can breathe. Outer space is anything outside of this atmosphere. And inner space became the deep sea, especially reminiscent of the explorations of Cousteau and ilk.
- mb7733 4y agoAt least where I'm from, "space" is just a short-form for "outer space". But it sounds like your understanding is that "space" refers to the area within the atmosphere? Is that the really case?
- mrtnmcc 4y agoThe view is not much different than at the 20 miles easily reached by high altitude balloons.
- 8bitsrule 4y agoDepends on how we define the boldly in 'boldly go'.
- remarkEon 4y agoThe wiki for this flight[1] is unfortunately pretty thin. I'd really like to know the story behind how they got a V2 rocket out to White Sands and actually conducted this flight. It has to be a fascinating story - one I hadn't even heard of until now. I assume this was broadly part of Operation Paperclip, and either fully assembled rockets or their components were moved out of Germany and to the United States at some point. [1] https://en.wikipedia.org/wiki/V-2_No._13 https://en.wikipedia.org/wiki/V-2_No._13 Edit: I take it back, the wiki does link the final project report[2] from 1952 that goes into detail about how this was accomplished. It's worth reading. [2] https://archive.org/details/finalreportproje00whit/page/2/mode/2up https://archive.org/details/finalreportproje00whit/page/2/mo...
- flohofwoe 4y agoBoth the Americans and the Soviets shipped all material they could find about the V2 to their respective countries, this included both completely assembled rockets and parts which where then assembled and tested at home with the help of German specialists (the Soviets also had "their" group of German rocket scientists, just not as "high profile" as the group around von Braun). The first Soviet ballistic missile "R1" was an almost 100% clone of the V2 for instance: https://en.wikipedia.org/wiki/R-1_(missile) https://en.wikipedia.org/wiki/R-1_(missile)
- Maursault 4y ago> Both the Americans and the Soviets shipped all material they could find about the V2 to their respective countries Really sucks, to put it mildly, because it kind of entwines space exploration with Nazis, attaching ethical questions to JWST and even to our beloved "One small step for..." audio clip. But maybe we can sift out whether the V2 would have been developed regardless of whether Nazis came to power in Germany. What if we had a time machine, and could very surgically stop the Nazis ever coming to power and prevent the Holocaust. Would it also cost us the V2 rocket and a lot of time getting to where we are now with space exploration? I know it is a dumb hypothetical, but I want to know Nazi tech is irrelevant.

- swader999 4y agoFlat as a pancake!
- vmception 4y agoI really like how NASA started using dynamic range better to show stars in the background of stills and videos of the earth in response to how many people were swayed by flat earth logic (“where are the stars? there arent any!”) Exposure was an afterthought to astronauts and now they make more aesthetically pleasing images by using basic photography principles (and better digital sensors)
- sph 4y agoFeel free to correct me, but the whole flat earth idea is mostly an Internet-era thing that is spread as a meme and nobody, apart from a _very small_ group of lunatics actually believes it. In history there have always been true flat earthers, but they've become rarer and rarer until the Youtube era in fact, when the concept of it became so widespread because it's "funny" and not at all representative of how many people truly believe in it. The whole thing is people laughing at someone that doesn't really exist.
- vmception 4y agoYou’d be surprised. There are people that got roped up in it who were not lunatics, some have since recanted a lot of what they said and mentioned how it happened. It mostly comes down to people “doing their own research” and feeling like theyre being proactive but really Google, Youtube and Facebook sent them down a rabbit hole of related content, which in this case was a “grand conspiracy few people know of”.
- ncmncm 4y agoWhat would be really strange would be if the Germans never did this.
- mtlmtlmtlmtl 4y agoThis reminded me of the famous 1993 paper by Sagan et al[1] where they used the Galileo probe to try to detect life on Earth through analysing the spectra of the athmosphere and detecting chemical concentrations that could only be explained by life(or that's the hope anyway). For me the most exciting prospect of the JWST is the ability to analyse the spectra of atmospheres around exoplanets. We could have tantalising evidence of extrasolar life in just a few years. [1]: https://www.nature.com/articles/365715a0 https://www.nature.com/articles/365715a0
- Maursault 4y ago> We could have tantalising evidence of extrasolar life in just a few years. Isn't the math tantalizing enough? Spoiler: there is.
- Georgelemental 4y agoHow exactly? Sure, space is astronomically big, but maybe life is equally astronomically unlikely. We just don't know
- Maursault 4y ago> maybe life is equally astronomically unlikely All evidence points to the contrary. Once you have conditions that support life, given time and entropy, inevitably there is life. I don't think finding life out there is much of a going concern. But I think maybe whether there is Intelligent Life™ out there, is. Even if Earth is the first evolution of life in the Universe, it is too late, it's going to be everywhere it can be eventually, because waterbears can survive space (and God knows what else), and sometimes things hit Earth and knock off parts with waterbears, given enough times, one of those is then bound to hit another Goldilocks planet, and there you have it.
- mtlmtlmtlmtl 4y agoThe problem with this is we just don't know how likely abiogenesis actually is. We can make vague guesses based on very general things like the abundance of certain elements. At the end of the day though, we just don't know how many factors were necessary for the formation of life on earth(or indeed whether it formed on Earth in the first place). There could be any series of unlikely characteristics about our solar system and the Earth that were all necessary for life. One example is the Earth's unusually large moon, likely caused by the Earth colliding with another planet during the formation of the solar system. Another is the seemingly unusual variety in types and sizes of planets within the solar system(see the Grand Tack Hypothesis), and the effect of Jupiter shielding the Earth from massive meteor bombardment. Sure, maybe it's highly unlikely that life exists only on Earth. But even so, the question of just how common it is is very interesting. As for tardigrades, note that they've been shown to be able to survive 10 days in space. That's a far cry from being able to survive an interstellar journey, land on a planet, survive and multiply as the only species on said planet, etc. Extrapolating all this from surviving space for 10 days in an experiment is a pretty big leap. And indeed, I've never heard a scientist dismiss the importance of discovering extrasolar life as "not much of a concern" I find this view utterly absurd.
- cesaref 4y agoI'm surprised the Germans didn't take any shots like this when developing the weapon. The idea of strapping a camera to the outside of the rocket doesn't sound particularly novel, but I guess they might have used telemetry to learn everything that needed to know?
- flohofwoe 4y agoFrom reading about the topic I seem to remember that the rocket's (initial) flight path was mostly observed from the ground, but this text mentions that "early test rockets" had a camera onboard (just not on the outside) with the downside that the film had to be retrieved after splash, and that later development models used a radio transmitter instead: https://www.centennialofflight.net/essay/Evolution_of_Technology/V-2/Tech26.htm https://www.centennialofflight.net/essay/Evolution_of_Techno...
- mytailorisrich 4y agoIf you're at war and under pressure to develop operational missiles, and then to use limited resources to manufacture them, taking pictures may not be on your list of priorities.
