Blogging a Ride on the 'Vomit Comet'

An anonymous reader writes "Four Duke engineering students have launched a weblog to document their preparations and impending ride on NASA's 'vomit comet.' The students will study the effects of microgravity on the shapes of cells and the positions of their organelles, such as the nucleus. The schedule is subject to change, but the students expect to take their 12,000 foot plunges Monday in NASA's KC-135A. They plan to provide photos and video."

    Put the plane into a dive accellerating at g. Effectively the occupants are in free fall but it feels like there no gravity.

    > 12,000 foot plunges

    s = ut + 1/2 a * t * t;

    with a vertical velocity of 0 from the dive ...

    that makes it

    t* t = 819.something ...

    makes it less than 30 seconds of no gravity ??

    And add the final deceleration when g-forces really pull you down ? ...

    *vomit* ...

    throwing up and seeing it form a perfect sphere of liquid puke (cohesion in no gravity should be strong enough) is worth the trip.. especially if you blow it towards someone else :)

      Right. I flew on the vomit comet (they prefer to use the term Weightless Wonder) a couple years ago as part of this same program. It is approx. 30 seconds of 0-G followed by 30-45 seconds of 2-G. And those 2-G's come on quick, so the flight director on board yells "Feet down, coming out." at the end of every parabola so that you don't end up smashing your face into the floor of the cabin. As far as vomit goes, they give much training prior to the flight on what to do if you're going to toss cookies.. they give you two vomit bags to stuff into the chest of your flight suit for quick access to your mouth. They also give you a double dose of motion sickness medicine the morning of your flight.

    Anything in free-fall is effectively at zero gravity. The plane climbs to a high altitude and goes into a dive.

    The ISS is at an altitude of about 370km. With Earth having a diameter of 6000km and using Newton's Law of Universal Gravitation, the gravity on the space station should be 88% of what it is on earth's suface. (6000/6370)^2.

    The reason it is a zero gravity environment is because it is orbiting the Earth. That means it is effectively in freefall, always falling towards the Earth, but it has enough sideways motion that it keeps falling around the planet.

    Quite a few of the scenes in Apollo 13 were filmed onboard the KC-135, which is why the weightless "effects" look so good -- they're real.

    If I'm not mistaken, the vomiting happens at the bottom of the arc. As such, you probably won't get to see video of zero-gravity vomit formations (hopefully to classical music).... Just some dudes sitting on the floor throwing up.

    It was similar shenanigans which saw Barry Humphries (AKA Dame Edna Everage) banned as a teenager for life from an Australian airline - a ban which remained throughout his stardom and ended only with the closure of the airline.

    His notorious "sick bag" prank involved carrying a tin of condensed soup onto an aircraft, which he would then surreptitiously emptied into an air-sickness bag. At an appropriate juncture, he would walk up and down the aisle pretending to vomit very loudly and violently into the bag. Then, he would proceed to eat the contents to the horror of the passengers and crew, many of whom would start vomiting (for real) as a result. Best...Prank...Ever!

    Zero Gravity Corporation (ZERO-G) is booking seats for Vomit-Comet-like weightless flights. The 'ZERO-G Experience' has 20 parabolas--made up of Martian (1/3 gravity), lunar (1/6 gravity) and zero gravity parabolas--and costs $2,950 per seat. Peter Diamandis (founder of the Ansari X Prize) is the CEO.

  13. Note from a Vomit Comet Veteran by jezor · · Score: 2, Interesting

    I rode the Vomit Comit back in 1987, as a research participant in Space Adaptation Syndrome (i.e. zero-g motion sickness) studies at the Ashton Graybiel Spatial Orientation Lab at Brandeis University. We did 2 or 3 days worth of flights, essentially a 2-mile high roller coaster (40 or so 10,000-foot parabolae with 30 seconds of zero-g at the top of each parabola) over the Gulf of Mexico, and it was truly one of the most amazing experiences of my life. While I didn't get to do the zero-g acrobatics you've seen on TV or in "Apollo 13" (I was doing baseline susceptibility studies, and was seated), I had the fun experience of being hit while blindfolded by a floating teddy bear in a space suit. While I never got to go back (scheduling problems, an engine failure on the ground prior to a flight, etc.), I wouldn't have missed it for the world. And while I only vomited once (some professional researchers were so susceptible that they had to sit out the second and third days to recover), I will tell you that the smell of a padded aircraft cabin with poor ventilation after one of those flights was...powerful. {Professor Jonathan Ezor, Touro Law Center}
