Crew Demo-2

Crew Demo-2

After standing down from launch on Wednesday, May 27, SpaceX is now targeting Saturday, May 30 for Falcon 9’s launch of Crew Dragon’s second demonstration (Demo-2) mission from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. This test flight with NASA astronauts Bob Behnken and Doug Hurley on board the Dragon spacecraft will return human spaceflight to the United States.

The instantaneous launch window opens at 3:22 p.m. EDT, or 19:22 UTC, with a backup instantaneous launch opportunity available on Sunday, May 31 at 3:00 p.m. EDT, or 19:00 UTC. Tune in here to watch the launch webcast. Coverage will begin about 4 hours before liftoff.

Demo-2 is the final major test for SpaceX’s human spaceflight system to be certified by NASA for operational crew missions to and from the International Space Station. SpaceX is returning human spaceflight to the United States with one of the safest, most advanced systems ever built, and NASA’s Commercial Crew Program is a turning point for America’s future in space exploration that lays the groundwork for future missions to the Moon, Mars, and beyond.

    So 2020 is kind of like all the sci fi movies of last 20 years compressed into reality..

      It’s really not a big deal, they are going to ISS, not to Mars, however it’s good they can use a domestic vehicle.


      Funny you should say that, I was listening to The Launch by Trevor Rabin all that afternoon looking forward to the liftoff lol, gutted they cancelled with minutes to go but the safety of the astronauts has to be paramount of course. I’ll be back here tomorrow on the edge of my seat with an ice cold beer watching history take place. 2020 has been a crazy year, we’re living in very interesting times indeed.

    • rafftaman says:

      Karandras I think the fact that they are able to reuse the hardware for repeated flights, less wastage and more economical, plus the fact that this is a staged process with possibilities of further space exploration beyond LEO. It’s a big deal, akin to development of commercial flights in the 1950’s with Jet engine era. This year we should be happy with any wins.. been tough on many people !

      @Science Revolution your vibration radiation system is an absolute mess that won’t work, electrostatic forces are high frequency systems; your charged particles need to go, let me guess, SPECIFICALLY ONE ASTRONOMICAL UNIT to reach earth.
      The only logical times at which it would work would be when solar flares go close enough. how are your particles vibrating btw? heat? and what’s heat from? fusion reactions which are compressed by, you got it, GRAVITATIONAL KINETIC *ENERGY*, WHICH IS IN *JOULES* , BUFFOON.
      I pray each day that you’re a troll. “Electrons are on the surface of all matters/masses/atoms” that sentences is like saying “water is made out of molten ice”, it’s not wrong, it’s stupid; the coulomb force you’ll get from that doesn’t works like THIS, it’s defined again in JOULES, which is *ENERGY*, which makes your entire point wrong. besides, what the hell carries your vibration thru outer space? your gamma rays? what are those, giant plasma gooey strings? bring your equations to the table then.
      note that electrons act both as waves and particles, and by assuming their existence, you literally declared electromagnetism was a thing.
      You basically said “Electromagnetic forces don’t exist, long live electromagnetics forces” there
      You also recognized mass to be a thing. I don’t know how wrong you are, but you certainly are flying above the literal scale there, if you were on a skateboard your air would be unreal.
      radiation IS photon particles. saying there’s no known mechanism is the most anti-scientific approach to a problem. if you have a problem, you look at it and fix it, you don’t just say “eh no known mechanism”. Explain triboluminescence creating those photons from breaking sugar crystals and forcing their electron to produce photons thru electromagnetical mechanisms that convert your kinetic energy into luminar energy… your theory isn’t disinteresting, but it’s absolutely wrong in many points and require rework
      the coulomb force is a cool thing, but it’s too short. you’re misunderstanding several concepts and forgetting that photons have momentum.
      besides, what’s a vibration?
      it’s a literal wave . it’s oscillation , except it’s kinetic.
      replacing photons just doesn’t works.
      one more thing, you’d be blind if that was the case; 1: they’re made to get a luminar input, not a coulomb force input, but I can predict your next move that you’re telling me that “they’re made for coulomb force input” , except you’d have a half ton of noise going thru your sight because of noise vibrations ; how do you explain colors, and the monitor you’re watching, and triangular optical prisms that split sunlight?
      as danish said, you’re a jester to the scientific community, your theory is equivalent to the one of a flat earther if not slightly less illogical thankfully. you’re denying the existence of an entire field of science.
      another thing how do lasers work? you’re going to tell me those coulomb forces can be lined and made to work altogether very precisely? wwwwwwwwwwwwww

    It’s okay, SpaceX. You go when you feel like it.

    • Valentine says:

      David Stanescu I used the light analogy since Gravity propagates at the same speed.

      The more I read from you the more I just feel like you’re a prime example of the dunning kruger effect :p

    • David Stanescu says:

      @Valentine hey , fuck off

    • Valentine says:

      David Stanescu *_yikes_*

    • Saden Uttie ! says:

      David Stanescu don’t worry about these people. I have talked to many and most of them just want to feel special because they know something others don’t. Let them stay in their dream world

    • David Stanescu says:

      @Saden Uttie ! i waste my time trying to educate some of them but it is useless . In this world we need dumb people too so we can make money off of them ( it couldnt sound more capitalistic :))) )

  6. Marco Polo says:

    And then, when the mission is over, and they make their way back to earth, it will be ‘Return of the Dragon’.

      Kevin Hemelrijk actually unstart procedure😂

    • Hypothetical Superposition says:

      @Zé Scotto di Vettimo There are two backup systems in the vessel. There is one other touch screen backup system and another manual button&switch system underneath the dashboard, but the flight is mostly automated anyways.

    • shyvha beauregard says:

      @HoboWild user interface is human oriented lol, look at the screen, it’s ten if not hundred times less bothering than the old shuttle’s controls lol

    • Zé Scotto di Vettimo says:

      @Hypothetical Superposition cool! waiting for the big Saturday.

    I’m loving the design of the SpaceX crafts, we’ve seen the same old Nasa interior/exterior designs for decades now, it’s refreshing to see a new more aesthetic design.

    • Daniel Rodrigues says:

      I love these futuristic designs so much compared to the clunky designs everyone else was using up till this point! 😍 Let’s hope this works out well (or better) than all the previous spacecrafts, so it can be cemented into our history and confirmed for our future.

    Damn, my butt would hurt just sitting there.

    • optimus moose says:

      KnowZz in space it won’t be uncomfortable as they won’t be sat on then they will be floating just strapped to the seat so actually it’s more comfy in space and also it’s there back that will hurt as there sat upright

    • Patrick McDermott says:

      They are gonna be sitting there for at least 20 hours, it takes a while to get to the iss

    • optimus moose says:

      Patrick McDermott yes but sitting there in 0g meaning they will be sat down sure but gravity won’t be pulling them down so the chairs we actually become almost unnoticeable

    • Patrick McDermott says:

      @optimus moose oh shit I forgot about no gravity😂😂😂

    • Firz says:

      Yeah but i think that suit is hot as fuck

  10. Roy F-W says:

    I love the looks of the Space X Launch/Re-entry suits. I would love to see them put different coloured patches on the sholders or chests of the suits for the different astronaughts. Just to make it easy at a glace to see who is who in that white on white capsule.

    • Ronald Crandall says:

      @Igor Schmidlapp probably few options on material they had to be able to pressurize. That being said any other color, even white would have been better than gray on the boots I feel like xD

    • Steven Kuski says:

      they could use startrek colours, red for command, yellow for operations and blue for missions specialists.

    • Steve Perry says:

      @Steven Kuski Red is security and no one is going to want to wear a red shirt 🙂

    • Eat Ham says:

      @Steve Perry If the astronauts were red shirts they wouldn’t even get a chance to leave the ground 😂

    • OtakuEdits says:

      @toordog And to add to insult, the person’s channel banner art is of space with a spherical planet in it. Maybe you should look a little further instead of assuming the worst in someone.
