galaSAT VI

galaSAT VI was launched from our High School last May 16, 2021. We couldn't share our project with classmates and families because of COVID19.

The launch was made from the playground of Antonio Gala High School at about 11.00 am and almost an hour and half later the payload landed close to San Sebastián de los Ballesteros. Because of some mistakes on APRS and LoRa comunication we couldn't find out our payload. Fortunately, a farmer (Mateo) who found the payload two days later phoned to tell us great news.

galaSAT THREE at night

galaSAT THREE has been our third flight. Due to problems beyond our control, the launch took place on May 13, at 2:15 a.m. However, It has been a great learning experience and an opportunity to grow. galaSAT THREE reached the bursting point (25584 meters) at 03:33 am, while some members were sleeping :). After a few hours to rest, we began the recovery at 7:30 am and twelve hours later we were back at home.

galaSAT III will take place in May

Next launch will take place in May this year 2017. A renewed human team is going to face a new challenge: galaSAT THREE. The team is composed of nineteen people (four girls and fifteen boys linked in a common purpose).

There are several goals we would like to achieve on this new misión: reach more than 100.000 feet above sea level; set up a pressure sensor to check out how air pressure changes at different altitudes; design and make up a DIY parachute to get a safety return.

galaSAT TWO video has come

galaSAT TWO is the second flight with the goal of testing new electronic equipment. Last 3rd June galaSAT TWO reached the bursting point (16136 meters) at 11:56 am, while we are driving toward the landing site.

Here comes a new challenge!!!

A new human team is going to face up to a new challenge: galaSAT TWO. A team made up of 21 students from two different grades. This time, the human team is composed of 9 girls and 12 boys who are working together.

galaSAT TWO team

There are some goals we want to achieve on this second misión: reach more than 27.602 meters at bursting point; set up a pressure sensor to check out how air pressure changes at different altitudes; set up an ultraviolet light sensor to prove how UV light changes at different altitudes; implement a top camera which allows us to record the bursting point and know how the parachute works during descent.

galaSAT on educaLAB

Thanks to our workmate Anibal de la Torre, we have taken part in STEMooc to show how our project permit us to develop Education Technology Standards for Students: analyze data, plan and manage activities to develop a solution or complete a project, process data and report results, communicate information and ideas effectively to multiple audiences using a variety of media and formats, use models and simulations to explore complex systems, contribute to project teams to produce original works or solve problems…

Flight Comparison

Thanks to information from APRS tracker we can compare and validate the predicted flight models vs the real flight. As we can see in the image below, CSUF predictor has been more accurate than ASTRA predictor. The straight line distance from CSUF Landing point to Real Landing Point was 3.33 Kilometers. On the contrary, the predicted flight model by ASTRA shows an enormous difference (17.38 Kilometers)

Temperature Logging

Galasat ONE began to ascend at 11:50 h and 86 minutes later the high altitude balloon burst reaching an altitude of 27.602 meters. The maximum temperature during that time was -36’5° C. During 19 minutes the payload was on free falling and our device logged a maximum temperature of -53° C at 13:22 h.
