Is it possible to have a space fire?
Spacecraft NASA "the SWAN" at the beginning of spring was delivered to the ISS consumables, total weight 3500 kg, June 4 the transport vehicle is disconnected from the American module on the ISS and some time later, June 11 was burned in the dense layers of the atmosphere. The fire on the module as it was inevitable and planned, it was conducted in the framework of science. Experiments on fire suppression in microgravity NASA conducted very often, in such instances, practiced methods of elimination of fires in space.
Ship to deliver cargo to the ISS was designed and built by the company Orbital ATK it was named after a famous astronaut from United States - S. S. John Glenn. After a safe undock in order not to damage the solar panels of the space station, the transport module was geared hand manipulator and slowly retreated to safe removal, where it was allowed to float freely. The robotic hand is controlled American astronaut Jack Fischer. The ISS was flying just at the height of 402 km over the Atlantic ocean.
Truck "S. S. John Glenn" shoot was a pity, but this is a necessity. On-orbit as a module for the ISS it is absolutely useless, it after discharge has become a common ballast which affects the weight station, but does not bear any practical load. Therefore, it was NASA decided to use the module in the experiment SAFFIRE III. SAFFIRE III is the third experimental experience in watching how the fire in zero gravity and as possible any fire can be quickly extinguished. The first test conducted in the past 2016, then just burned a cargo ship loaded with sensors. This experiment allowed us to obtain data on the speed of spread of fire in zero gravity.
Experiment SAFFIRE III involves the use of "Swan" as experimental sites for studying the potential fire hazard in a similar module on the ISS, so before you burn the module it created the same conditions as on the ISS. When all was ready, has been controlled the fire a large piece of material. Next we studied the spread of fire at different air flows. After the fire the ship was burning inside for about 20 minutes, after that the ship still flew a bit and going into the dense layers of the atmosphere burned down completely.
According to the results of the experiment SAFFIRE III received a lot of new data that will be used in the design of space capsules. The same will be utilized to update existing ships and technical solutions. New, modified ship again will take part in the test of fire no earlier than 2019.
SAFFIRE IV-VI it is planned to conduct more grandiose fires through containment systems and fire extinguishing systems in orbit.
Before the cargo ship Cygnus burned, he still managed to launch 4 small satellite series is the Lemur-2 cubesat to group Spire Global,these satellites need company Nanoracks for accurate weather forecasts in the areas of navigation.
