  • The vanilla with swirled chocolate sauce ice cream cups won't melt on their three-day journey to the space station thanks to a freezer on board the Dragon capsule
  • e first time we are taking powered cargo up. We are taking up a GLACIER freezer, which has refrigerated science samples in it
  • The mini-fridge sized freezer previously flew aboard the space shuttle.

  • GLACIER, or General Laboratory Active Cryogenic ISS Experiment Refrigerator, is primarily used to preserve science samples that require temperatures between minus 301 and 39 degrees Fahrenheit (minus 160 and 4 degrees Celsius
  • The brand of ice cream flying in the Dragon's GLACIER is Blue Bell Creameries, a Texas dairy that has a strong fan base in Houston
  • Blue Bell ice cream has been flown to the space station before. The creamery's cups first launched to the orbiting laboratory in 2006 on board the space shuttle Atlanti

  • altitude of 53 miles (85 km), the thermosphere transitions into the mesosphere, an atmospheric layer known for its faint clouds, as well as electrical discharge events called red sprites and blue jets.
  • e stratosphere extends from an altitude of 6 miles (10 kilometers) up to about 30 miles (50 km) above the surface. The air pressure drops from 10 percent of its value at sea level to just 0.1 percent
  • , unlike in the layers above and below, absorption of ultraviolet sunlight by ozone causes the temperature to increase as you move up in altitude
  • coupling of temperature with altitude prevents convection from happening, and so the air in this layer is dynamically stable.

Supersonic Skydive's 5 Biggest Risks: Boiling Blood, Deadly Spins, and Worse - 0 views

  • atmosphere above 12 miles, or 63,000 feet (19,200 meters)
  • is so thin that, if not protected, human blood will literally boil
  • , Baumgartner's airtight suit and the capsule around him will be continuously pressurized to create a personal atmosphere that isolates him from the void surrounding him
  • The smallest crack in this protective layer would cause almost immediate death
  • It is assumed this is what occurred on previous attempts to break Kittinger's record. Russian Pyotr Dolgov (1962) and American Nick Piantanida (1966) both died, most likely due to depressurization at extreme altitude
  • Baumgartner's balloon will be stressed by the cold, constructed as it is from plastic film just 0.0008 inch (0.02 millimeter) thick, to optimize weight-to-lift ratio
  • his balloon and capsule will pass through an atmospheric layer called the tropopause
  • Wind Could Blow Baumgartner off Course
  • Baumgartner Could Spin Uncontrollably, Even Fatally
  • flat-spin risk can be mediated with a technology first developed for Kittinger: a stabilization parachute to prevent further increase in rotation, deployed on command, or automatically if -3.5 G's are achieved.
  • Baumgartner has his eyes on a new speed record
  • won't open automatically
  • he will assume a rigid aerodynamic body position for the entire free fall—head first, arms at sides—and hope for the best.
  • Sonic Boom Could Do Unknown Damage
  • If Baumgartner becomes the first human to achieve supersonic speed with just his body—and without breaking his body—he will break new scientific ground.

  • The first of NASA's contracted cargo resupply flights to the International Space Station now has its own mission patch, courtesy of the company launching the spacecraft.
  • The flight, referred to as Commercial Resupply Services-1 (CRS-1), is the first of a dozen resupply flights for which NASA is paying SpaceX $1.6 billion to fly.
  • The CRS-1 mission patch, which borrows its shape from the Dragon capsule, shows the solar-powered spacecraft grappled by the space station's Canadarm2 robotic arm as it is being brought in to connect with the orbiting outpost's Harmony module
  • ...3 more annotations...
  • Almost camouflaged with the patch's green-colored North American continent is a four leaf clover. The symbol for luck, the clover has become a regular feature on SpaceX's insignias since the Hawthorne, Calif.-based company's first successful Falcon 1 launch in September 2008
  • Based on pre-launch photos, the CRS-1 emblem does not appear on the Falcon 9 rocket or the Dragon capsule
  • embroidered versions of the patch may fly to the space station and back as part of the mission's Official Flight Kit (OFK) of mementos to be presented to NASA and SpaceX team members for a job well done.
