Last week the National Aeronautics and Space Administration (NASA) successfully completed an experiment with a suborbital, or sounding, rocket aimed at testing out new technologies before integrating them into other projects. The suborbital flight on October 7th was launched from the Wallops Flight Facility in Virginia on the Eastern seaboard of the United States, testing a ‘modified Black Brant sounding rocket motor, launch vehicle and spacecraft systems and sub-payload ejection technologies.’ 
Interesting enough, but during the test they released a number of vapor clouds into the atmosphere, releasing a mixture of chemicals that are well-known to those who are closely examining the growing problem of geoengineering and chemtrails. The skies over this area were alight in strange celestial clouds colorized by high-altitude discharges of barium and strontium.

During the test of the deployment system for the vapor clouds, four sub-payloads with mixtures of barium and strontium will be ejected from the main payload and the vapor will be deployed while the payload is descending. The test also will include the release of vapor from two systems on the main payload during the descent portion of the flight.
The ejected sub-payloads will release the vapor at about 130 miles above the Earth. The main payload releases will occur at an altitude around 118 miles.
The barium-strontium mixture produces a cloud with a mixture of blue-green and red color. The blue-green part is neutral, i.e. not charged. Strontium is used to enhance the visibility of the neutral flow. 
Barium and strontium, along with aluminum, are the 3 of the most commonly used chemical agents in atmospheric geoengineering projects, which have been used by the US government in weather modification projects since the 1950s.

This recent experiment proves once again that NASA and the US governments do in fact use atmospheric spraying of toxic chemicals for various research and experimentation purposes, although who really knows what they’re up to?
