  1.  @JoshuaBerner  It takes a special kind of hubris to make a claim that obviously nonsensical.
    17
  2. This was all easily verifiable truth. Stop calling events 'lies' because they don't agree with your warped worldview.

  3. NASA is given money to advance our knowledge. You many not be curious, but enough of us are.
    3
  4.  @jaroslavpesek6642  When Genesis crashed, they didn't do that. In fact, there are 0 instances where NASA has faked footage of anything.
    3
  5. Nice real footage, you mean.
    3
  6. It's possible the drogue stayed inside, on top of the main. Then the action of ejecting the main parachute would have shoved the drogue out as well.
    3
  7. When Genesis' landing failed, NASA didn't cover it up. They published the crash. There's no point in covering up anything. Those samples are going to be distributed to researchers all over the world, and they would notice if they were handed fakes instead of actual samples.
    3
  8. False. We have video of the actual sampling event.
    3
  9. Every video we get from the space station is real. Hundreds of people have been in space since the last Apollo mission. You have been misled by grifters who take space station videos and claim they are fake. None of their arguments hold up to scrutiny.

  10. Rock that falls to the ground for free is thoroughly cooked by the entry process, changing its structure and composition. We want a sample that's not been cooked.

  11. Deimos, with a radius of 6.2 km, has an escape velocity of ~25 km/h (xkcd comic 681). When you jump, your initial vertical speed is 2.45 m/s or 8.8 km/h. Playing with an escape velocity calculator a bit, an object with a mass of 1E14 kg and a radius of 5 km is small enough to escape by jumping.
    2
  12. That's because the contents have not been seen yet.
    2
  13. Nope. We've been collecting data on exactly that for decades. Look up the LDEF mission, for example.
    2
  14. The biggest space project of the past 30 years was the ISS. Its goal: to learn how to live and work in space. This is essential knowledge for becoming a space*faring* species.
    2
  15. The drogue chute didn't open, so for a while it looked like the capsule was going to crash.
    2
  16. Why is it that people like you just blithely assume the team didn't think this through?
    2
  17. The transmission kept stuttering throughout. Sending high-bandwidth live video from a moving aircraft remains hard.
    2
  18. Glitching is to be expected: a fast-moving aircraft is sending live video via a radio link. This tends to be unreliable, which is why the video is also recorded on board the aircraft. As Scott indicated, because there was no drogue deployment the capsule arrived at low altitude sooner than expected, which explains the early landing time. The claim that the main parachute deployed at 20 kft is then incorrect.
    2
  19.  @markpirola8152  The capsule wasn't overfilled. It was designed for 2 kg, they captured 250 g and the minimum wanted to collect was 60 g.
    2
  20. 'piece of cloth, packed for 7 years in the vacuum of space' is a bit more complicated.
    2
  21. Planes can take footage like this, and have been doing so for decades. Look up the recent Starship launch: this was filmed by a WB-57 too. Video glitches are normal when you try to send real-time video from an aircraft. It's pretty dumb to believe spaceflight is fake when you benefit from data and services produced in space every day.

  22. Congratulations, you win the 'biggest conglomeration of nonsense' award.

  23. ​ @jerryhoward6007  "impenetrable barrier above Earth": that barrier is impenetrable only to electrons. Satellites go through that "barrier" without experiencing any problem. "plasmasphere": a region of Earth's magnetosphere that is responsible for some radio phenomena. Not a barrier. "Lands beyond the pole/Antarctica/ice wall/Nos Confunden Map": flat-Earther nonsense claims. Earth is a sphere, Antarctica is just a continent.
    2
  24.  @jerryhoward6007  I have proof for all of it. 1. barrier above Earth: we've launched hundreds of spacecraft to altitudes greater than that "barrier", including geostationary TV broadcast satellites (which anyone can use by aiming a dish antenna in the right direction, confirming their existence and location) and GPS satellites (which anyone can use, confirming their existence and location). That also takes care of 2. 3. Anyone can measure the surface of our planet. You will find that it is curved, not flat. The ancient Greeks were able to figure out that Earth is a sphere. Nowadays, you can charter an aircraft and fly over the South Pole, and see for your self that there are no "lands beyond the pole".
    2
  25.  @jerryhoward6007  Why would I believe you when all of the evidence proves you wrong?
    2
  26. Nope. Glitchy coverage all the way through, as can be expected when you send a high-bandwidth signal from a moving aircraft.
    2
  27. Cohesion is maintained by gravity. Bennu weighs 10 million tons, that's enough material to create a tiny but noticeable gravitational field.
    2
  28. I can prove you wrong by looking at the sky and seeing satellites pass overhead.
    2
  29. Complete reality. It's a pity you can't distinguish between scams and actual science.
    2
  30. There is no reason to jump from a hiccup in a live video feed from an aircraft (a feed which had been glitching throughout, indicating they were losing data due to imperfect antenna alignment) right to "NASA swapped in a fake capsule". As Exhibit A, I present the landing of Genesis, which had a parachute malfunction and crash-landed. NASA showed the crash, and has been nothing less than completely transparent about the crash.
    2
  31. You need a Hebrew dictionary. Nasa means 'to lift up'. But NASA is not a word, it's an acronym. National Aeronautics and Space Administration.  Since its inception, NASA has been running real projects, providing real benefits to mankind.
    2
  32. Maybe you should read up on how the Osiris-Rex team planned for bringing this sample back, and the regulations that govern any sort of sample return, and the reasons behind those regulations. You know, actual data instead of a novel.
    2
  33. Luckily, not everybody is as indifferent to our origin and environment as you.
    2
  34. We have evidence that NASA does not do that, see the Genesis return capsule, whose crash was not covered up.
    2
  35.  @ardennielsen3761  A pressure of zero means there are no molecules in the chamber. Negative pressure does not exist.
    2
  36. The container was not hermetically sealed, air got in through the SRC Sample Canister Air Filter. After landing, the capsule was flushed with nitrogen.
    2
  37. That's just you. The video was glitching throughout, as can be expected when you're sending high-bandwidth real-time signals from a fast-moving aircraft.
    2
  38. This camera is observing an object 0.5 meters wide at a distance of 10 km. Quality is limited by the camera aperture, which is limited by the weight the aircraft can carry.
    2
  39. Varda has no reentry permission because the FAA is not convinced their reentry plan is solid enough. This is about aviation safety (having a capsule fly through airspace that's in use), not whatever's inside the capsule.
    2
  40. That's manual tracking, I believe. The capsule does not broadcast its position.
    2
  41. The sample is in a closed container inside. That doesn't get opened until the container is in the cleanroom.
    1
  42.  @KronosGodwisen  LDEF is just one example. The Apollo missions did similar experiments (though on a smaller scale).
    1
  43. The highest skydiving attempts are from about 38 km altitude. Baumgartner reached a speed of 1300 km/h. This capsule entered our atmosphere at an altitude of 100 km, with a speed of 43,000 km/h.
    1
  44. What was the distance between the aircraft and the spacecraft?
    1
  45. This was studied extensively with samples from the moon. Radioactivity levels are very low.
    1
  46. Convenient that the capsule was visible from the ground form an altitude far higher than any aircraft can reach.
    1
  47. Every year, there are about 100 rocket flights, and millions of airplane flights. Guess which ones are an actual problem?
    1
  48. They're not in the clean room yet.
    1
  49. That's actually not less expensive. It would have required Osiris-Rex to carry enough propellant to reduce its speed from 12 to 8 km per second. This requires tens of tons of propellant, which in turn would require hundreds of tons of propellant to get the spacecraft to Bennu in the first place. You'd need several Saturn Vs to launch a spacecraft that heavy.

  50.  @TheRealNewWhirledOrder  Evidence for gravity: 1. the behavior of the planets and moons in our solar system. They follow Newton and Einsteins laws of gravity exactly. We have ruled out other forces because those would be easily measurable on these large scales. 2. the Cavendish experiment, which demonstrates that any two masses attract each other. Again, we have ruled out other forces. 3. the behavior of objects on earth, and the changes in behavior depending on where you are, demonstrating variations in the gravitational field depending on the amount of material nearby (mountains, Earth's equatorial bulge). Gravity is the only possible explanation for all of these.

  51.  @TheRealNewWhirledOrder  The Apollo Flight Journal has hundreds of analog photos taken by every Apollo mission. Flickr has hundreds of thousands of photos taken by ISS astronauts. The NOAA has millions of photos of Earth taken by geostationary weather satellites.

  52.  @TheRealNewWhirledOrder  Surface tension plays a role at small scales, affecting only the edge of a body of water. A body of water 1 km long has a surface that is a section of a sphere. In the middle it is 4 cm higher than on the edges. This is not surface tension.
    1
  53.  @TheRealNewWhirledOrder  Every satellite orbiting Earth is evidence that the space above us is a vacuum. Satellites at higher altitudes stay in orbit for decades without slowing down, i.e. they do not experience drag.
    1
  54.  @TheRealNewWhirledOrder  There are objects in the sky that move. We (i.e. anyone with a telescope) can measure the distance to them and see how large the solar system is. Observation of the planets from Earth allowed us to learn the basics: some are rocky like earth, others are gas giants. We (humanity) have built spacecraft that have traveled to these planets to learn more about them.

  55.  @TheRealNewWhirledOrder  As I've already told you, the curvature we measure on large bodies of water has nothing to do with surface tension. We have measured the limits of surface tension. Anyone can do this by playing with a blob of water on a table. When a ship goes over the horizon and disappears from the bottom up, its path forms a curve: that is Earth's curvature. In some places, this curvature is visible with the naked eye from sea level. Eg. the Bonneville salt flats, and the Afsluitdijk in the Netherlands.

  56. The "lid" is a cover for the parachute. It doesn't need to be rigid, in fact it's better to have a flexible cover as that is less likely to damage the parachute.
    1
  57. That table consists of angle profiles, i.e. it's not wood but metal in some kind of coating.
    1
  58. The best estimate is 250 +/- 100 grams.
    1
  59. What you were looking at WAS the antechamber.
    1
  60.  @ashardalondragnipurake  Humans are transported in a pressure vessel, this parachute wasn't. Adding a pressure vessel for the parachute would have made the mission a lot more expensive due to all the extra weight.
    1
  61.  @jerryhoward6007  Then your "research" is flawed. We have known (not believed, known for certain) for 2500 years that Earth is not a flat disk but a sphere. All of the actual evidence shows this. You have fallen for pseudoscience and lies, produced by charlatans and grifters. None of their arguments hold up to scrutiny.

  62. It arrived at Earth at a much higher speed than the ISS, so you'd need a rocket engine and a huge amount of fuel to slow down. Using a reentry capsule, the atmosphere does the work of slowing the capsule down.
    1
  63.  @icesphere1205  Objects in low Earth orbit like the ISS move at about 7.6 km/s. To escape Earth, you have to accelerate to 11.4 km/s. To get to Bennu, you have to accelerate more to get to its orbit (about 12.2 km/s). So the probe was returning from Bennu at 12.2 km/s. Elon's car was launched to an orbit that reaches Mars, which requires a higher speed (the farther away from the sun, the more speed you need).

  64. Getting a sample from deeper down requires drilling (as far as we knew at the start of the mission). It was a surprise that the TAGSAM was able to push into the surface so far - and this means at least some of the sample will be from below the surface.
    1
  65. The sample container has not been opened yet, that will be done in about 2 weeks.
    1
  66. The tracks are color-coded by altitude.
    1
  67. Yes.
    1
  68. The operation is split into two steps. TAGSAM has an arm that pushes the sample container into the asteroid. A puff of nitrogen is used to push sample material into the container. Once the spacecraft has ascended from the asteroid, the container is placed into the sealed compartment of the lander. This means the seal is not exposed to flying rubble so it should stay clean.
    1
  69. No. The radiation intensity in space is not high enough to make the spacecraft radioactive.
    1
  70. Osiris-Rex is small and specialized. A cubesat would be unable to return a sample back to Earth, for example.
    1
  71. There is no life on Bennu. No chance of a disease developing there.
    1
  72. Having a 1-bar nitrogen atmosphere is a better protection from our atmosphere than having the samples in a vacuum. Vacuum chambers are never perfect, so there'll always be a tiny amount of atmospheric oxygen in the chamber.
    1
  73. You should read up on how they arrived at that decision. Summary: we do know enough to be sure there's nothing biological in that sample container.
    1
  74. It's not difficult to design a trajectory that is guaranteed to miss the asteroid if the spacecraft runs out of fuel.
    1
  75.  @nanunanu83  How are you able to keep these flying? Spares must have become a real problem.
    1
  76. There is no NASA document that proves a flat, stationary Earth. You have been misled. Emergency landings do not "prove" Earth is flat. That's a false claim made by a charlatan. His arguments have been disproven. Eric Dubay's "200 proofs" of a flat Earth have all been disproven.  There are no astronauts that claim Earth is flat.  In short, you fell for every single con in this area.
