Next Flight

Colorado Space Grant Demosat Flight

WE ARE GOOD TO GO for a Saturday Launch!! The launch is scheduled for 7:00am from the Limon Ball Fields (see the directions by clicking on the preceeding blue text). The cloud cover is such that we should be able to fly all the payloads together on one large balloon. A final check will be made early in the morning.

Payload weigh-in and stringing will start at 6:00am, please plan on having your payloads at the site at that time. Please note that it is an approximately 1.5 hour drive from the intersection of 1-25 and I-70 (the mousetrap) to the launch site. Plan accordingly.

This is a Colorado Space Grant Consortium Demosat flight. We are going to try to launch one 3000g balloon, but if the weather (cloud cover) does not cooperate, we will be prepared to launch two 1200g balloons that will not be limited by cloud cover. Three payload plans are attached below, two for EOSS-226 covering both options, and one payload plan for EOSS-227 (if needed). The launch has been moved to the Limon Ball Field site.

Weather and flight path predictions are posted here. These will be updated starting two week before the launch and will be updated daily. A number of usefull links are collected here. This site has several links that will be active only during the flight and several links that show predictions and weather observations that are relevant to this flight.

EOSS-226

This will likely be a 3000g balloon with all of the CSGC Demosats (payload plan posted below). If cloud cover does not allow, it will be one of two 1200g balloons that can be flow through cloud cover (1200g balloon payload plan posted here).

EOSS-227

This is an optional 1200g balloon that will carry half of the CSGC Demostats if we fly two balloons through cloud cover that prevents flying one 3000g balloon.

TR Breakfast: 
T&R Breakfast will be at Denny's in Limon at 6:00. Be sure to load Limon as a launch site by modifying your Locations.dat file in TrackPoint. This from Nick's 5/18 message: A. Open TrackPoint. B. Open the Setup form. C. You should be on the Launch/Grid/Pred tab. If not, go to that tab. D. Click on the little blue square beside Launch Site dropdown menu window. E. The Locations.dat File will open in Notepad. F. The new entry is: Limon,N,39,14.204,W,103,41.822,5383 G. After the addition is done and checked, save the file. H. Close TrackPoint and restart to acquire your changes. Depending on cloud conditions, if unfavorable, then we will fly two balloons. Set up TrackPoint to accommodate the second balloon if necessary. Enjoy this flight and be safe! Marty
