Zero Gravity Flights at Johnson Space Center

Floating in zero gravity is just one of the perks of being an engineer :) Our team at ADA Technologies got a chance to fly on 4 zero gravity flights out of Ellington Field in Houston back in early March.  We're currently under a subcontract for NASA to develop a fine water mist fire extinguisher for the International Space Station and had to make sure the design would function correctly without gravity.  Our experiment consistent of discharging the extinguisher into an enclosed box and then measuring the size of the droplets with a laser as they were suspended in mid air.

Each flight on the modified Boeing 727 nicknamed the "Vomit Comet" lasts for about an hour and a half and consists of 40 parabolas where the plane cycles through dive-bombing at 45° towards earth from 34,000 ft down to 24,000 ft in about 30 seconds before pulling up and then ascending back to 34,000 ft.  Kind of like the coolest roller coaster you could ever imagine. They give you a shot about 30 mins before each flight with some serious anti-nausea meds but still make you take bags with you in each pocket of you flight suit.  Luckily, I did not get sick on my two days of flights but the meds give you a weird dry mouth feeling and totally drain your energy after the adrenaline of flying is over. What people sometimes don't realize is that not only do you experience 0G at the top of the curve and all the way down, but on the way back up your body experiences almost 2G and it feels like you weigh 300 lbs.  It makes it pretty tough to even stand up (push-ups were near impossible) when the plane is ascending.

Below are a bunch of pictures from our experience along with a behind the scenes tour at Johnson Space Center where we got to visit both the ISS and the old mission control rooms, sit in the cockpit of the shuttle training module and tour the entire mock space station.  The whole trip was definitely a career highlight.

A view inside the enclosure during discharge. The little red foam extinguisher was tied to a string and we could tell when were in zero g when it started floating.
