    The nasa broadcaster called it a perfect bullseye landing about 5 times. A perfect bullseye, hit em right in the Pacific ocean.

    They later said it was less than 1 mile away from the target spot.

    A big benefit of the ocean is if the capsule loses all attitude control, it can still reenter and survive. But it will be a "ballistic reentry", much more punishing with the g forces, and also about 1500 miles short of the target zone.

    The Pacific Ocean makes it easy to ensure that those backup contingency landing sites are also safe landing sites.

    You can't easily go out to see a splashdown in the middle of the ocean, therefore space travel is fake.

    Except for all the private boats parked right outside of the restricted area watching with binoculars.

    If they are landing on land it would have to be in like a middle of desert/plains anyways and it's not exactly trivial to go watch in person either

    She probably assumes the landing location is entirely random, which is ridiculous to anyone who has even the slightest understanding of the amount of planning needed for space travel, but those people and the people who believe space travel is fake are not the same people.

    Russian capsules have returned to land since their very first launches.

    The decision has more to do with geopolitics than physics. Russia does not have a robust Navy with access to equatorial waters on which to land a spacecraft, the US does. Given the historical accuracy of landing a capsule it is actually a hell of a lot easier to drive a big ship to the eventual location than it is to drive a big truck into the middle of a desert. The reason western nations return capsules to the sea is because its easier to recover them there.

    Both approaches have technical challenges. Returning to land requires a slower landing speed (although as a percentage of the starting velocity of a spacecraft its a pretty insignificant difference) and landing on the sea requires the carrying of flotation devices and designing a capsule with buoyancy in mind.

    In other words this post is completely inaccurate.

    For a while (maybe still) Russian rockets even had a shotgun on board after wolves got to a landing first.

    It was a three-barreled gun that fired shotgun shells, rifle rounds, and rescue flares. 10 rounds of each type of ammunition were supplied. The stock could be detached and used as a machete.

    For a while, these guns were on every Soyuz capsule that docked with ISS, and they were under the operational control of the Soyuz commander. I've read that they may have been retired in 2007 because Russia finally ran out of the very unique ammo.

    The Russian system has a braking rocket that fires at the very last second to soften up the landing. On one early Soyuz mission, this rocket didn't fire, and the solo cosmonaut suffered substantial injuries from the landing.

    The Orion capsule hits the water at the final parachute speed of 20-30 mph without injuring the crew. But as you state, they also have to design the capsule for flotation and egress in potentially rough sea state.

    Boeing Starliner is designed for a land landing, but it uses deployable air bags instead of a braking rocket. It's not clear that Starliner will ever fly again after the RCS thruster problems.

    It's such a weird flip of philosophy given we've all heard the classic story of the US spending millions on developing pens that write in space while the Soviet Union just issued pencils.

    Choosing a retroburst system over trusty parachutes over water is wack, but as someone else pointed out it's more to do with their Navy than anything else. Plus knowing Russia's current capabilities, they'd probably forget to factor in the water being frozen or something stupid like that.

    That story is apocryphal.

    Pencils aren't suitable in space because the last thing you want are little wood and graphite shavings floating around the capsule.

    Both the US and Russia used grease pens.

    The Fischer space pen was developed by a private company with no public investment and was marketed to the government and public.

    I listened to Chris Hadfield describe coming home in a Soyuz capsul and it rolling a few times after hitting the ground. Land works but water sounds more comfortable, as long as you don't get sea sick on top of it all.

    When they were covering the Artemis landing, they mentioned that just returning to earth from weightlessness makes them pretty nauseous, so they get motion sickness meds before landing anyway. Ibuprofen or anti inflammatory meds too, since 1 G is hard on joints after a few days without it.

    Water isn't like in the video games. It's still a hard landing that you wouldn't survive if you were going too fast. There's just much more margin for error trying to hit the ocean vs. a plot of land.

    They had only imagined the moon flight...

    On July 21, 1961, Virgil I. “Gus” Grissom flew the second NASA Mercury-Redstone mission. But that trip, nearly identical to Shepard’s almost ended in disaster. Grissom’s capsule, Liberty Bell 7, sank after the successful splashdown in the Atlantic, and Grissom came close to drowning.

    The space race has a lot of "learning by doing" with some pretty icky lessons learned along the way.

    Does landing on the sea really require that much more braking when compared to land? Sure water has some give but I've always understood that, from a large enough hight, due to surface tension landing on water is the same as landing on concrete. But I ain't no physicist and by no means of the imagination a rocket scientist so I might as well be very wrong here lmao

    One of the advantages of water is even if your target area is measured in square miles it's all roughly at sea level. If you miss your target area on land you have to account for that and trees and wildlife and hopefully not buildings.

    Like the above said, you can do either, it's kind of a wash. But a water based landing does simplify some things.

    It's just that some (bad) people think that being woke is a bad thing, and they are overrepresented in the culture at the moment.

    To be fair, some (not necessarily bad) people also use woke to mean 'comes from a good place, but gets taken too far and is a bit cringe', similar to 'hippy-dippy' or 'touchy- feely' in the past, I don't hold that against them too much.

    I have had the displeasure of knowing several people like this. In the post-truth landscape we find ourselves, there are really people out there who will call your denial of their alternative facts "unscientific" because they think that science is just about questioning everything, and they know their perspective is the right one.

    Therefore, when their high school science teacher (who obviously hated them in particular for their good Christian beliefs) insists on ideas like the Earth being round, or the existence of climate change or—heavens forbid—evolution, she's obviously just trying to brainwash her students to believe her liberal agenda.

    This mission especially brought the "space travel is fake" crowd out. The rocket launch explodes over a deserted area, nobody's onboard, all the missions are faked, and the splashdowns are in restricted waters to sell the simulation.

    Usually this is on top of "well you can't survive the Van Allen radiation belts", as if radiation safety and shielding is not a problem we understood and solved before we even lit off Mercury.

    Ultimate reasoning for it is either a vague notion of "control", bread and circuses, or "they do this to defy God", because space isn't real and the Firmament lies above the sky.

    Yes, because the area gets a no-fly zone and navy ships go to get the capsule, it makes it "easy" to fake because the government controls the situation. Yes, this ignores a lot of other independently verifiable data, because that doesn't confirm biases. Yes, it ignores all the Soyuz landings over land. Yes, it ignores the facts that the Soviets and Russians do and did the same thing, as if a highly-planned re-entry might just happen in anyone's rye field. Yes, it's stupid. Yes, it's on purpose.

    The purpose of these questions people ask conspiratorially is not to get answers. It's to foment doubt. They don't want answers; if they did they could look it up and find an answer. They just want people to start questioning the official story, then they sell their own conspiracy to them. It's an old playbook, and people like Alex Jones have been using it for decades.

    This was because they had rockets that fired precipitously close to the ground which cushioned the landing to something like 20 mph IIRC. If those rockets failed for any reason there would be a very big splat.

    At an altitude of eight meters, the "Posadka" (landing) signal lights up on the cosmonauts' console and at an altitude between 1.1 and 0.8 meters from Earth, the Kaktus altimeter issues a command for the firing of the braking solid motors, DMP. The spectacular firing takes place around 0.7 meters above the surface, reducing the descent speed of the capsule to between 0 and 3 meters per second. A speed of 2 or 1.5 meters per second is considered average at the touchdown point. The structural loads on the capsule at the moment of DMP firing was quoted as 0.1 kilograms. These loads were reported to be the main reason for ruling out the reuse of the Descent Module.

    In case of landing under a spare parachute, the descent speed could reach as high as 9.5 or even 10.5 meters per second, but it is still considered to be survivable by the crew.

    Some additional cushioning at touchdown is provided by individual crew seats, known as Kazbek (Kazbek-UM on Soyuz TMA) equipped with custom-fitted liners for each crew member. As a last resort, the bottom of the capsule also designed to absorb the shock of a particularly bad impact. https://russianspaceweb.com/soyuz-landing.html

    That reminds me about Vladimir_Komarov on Soyuz_1.

    He went up there knowing he was likely going to die because of the build problems with the early Soyuz capsules.

    The module crashed into the ground at terminal velocity, killing Komarov, at 6.24 a.m. ... Soyuz 1 engineers reported 203 design faults to party leaders, but their concerns "were overruled by political pressures for a series of space feats to mark the anniversary of Lenin's birthday".
