MM’s Wed Wx Forecast for Sept 21

NASA successfully launched four university experiments on September 21, 2012, on a Terrier-Improved Malemute suborbital sounding rocket from the agency’s launch range at the Wallops Flight Facility in Virginia. The rocket lofted the experiments to an altitude of 95.4 miles. The experiments were recovered from the Atlantic Ocean and they will be delivered to the university teams this afternoon at Wallops.

The launch was part of the RockSat-X educational project, which was designed to provide students hands-on experience in designing, fabricating, testing and conducting experiments for space flight. The project was a joint effort between NASA and the Colorado Space Grant Consortium.


Be sure and stay tuned for my coverage of the Crew-5 rocket launch from the Space Coast on October 2-3! I will have exclusive coverage via the NASA Social I was selected for. Be sure and tell all all space enthusiasts in your life! I will also cover the event on Facebook.

By Saturday, the heat begins returning. with southerly flow and sunshine. That southerly flow will bring increased rain chances back into the area by Sunday.
