What is cansat?

Team LarkCan is happy to announce that we will be representing Gymnasiet Lärkan in the Nordic satellite competition for secondary school. The competition will be held on 23rd to 26th April 2019 at Andøya Space Center in Norway. And if it goes as we hope we will be heading to Medicina, Bologna, Italy on the 24th to the 28th June 2019 for the European CanSat competition.

CanSat is an educational project that includes building a satellite the size of a soft drink. A CanSat contains all the major subsystems like power, sensors, and a communication system into such minimal volume. The CanSat is then launched to an altitude of a few hundred meters by a rocket or from a platform or captive balloon, where its mission begins.

Each team has the same primary mission. After release and during descent, the CanSat shall measure air temperature and air pressure. And then transmit the data as telemetry at least once every second to the ground station. For the secondary mission, each team will select their own one.

Our Mission

Our secondary mission is to measure solar- and UV-radiation. This will be done by the solar- and UV-sensors in the air before the CanSat touches the ground. But it will also continue to measure after landing and therefore function as a weather station. This will be done thanks to the solar panels covering most of the surface area of our CanSat. With the power from the solar panels, the CanSat will be able to recharge its' batteries and then continue to collect data. We aim to make the CanSat as energy efficient as possible.

This idea could be used for two different purposes. Because its size and not being that expensive it could be used for research on another planet, such as Mars for example. A number of these could be launched to Mars over a bigger area. And because of our CanSat would be able to recharge itself it could operate over a longer period without having to be brought back for a recharge. The other purpose is to provide us important information about how strong sunscreen one should use that particular day and in that way help in the prevention of melanoma. Melanoma is a serious type of cancer that develops from the pigment-containing cells in our bodies. Melanoma often occurs in the skin and is known as skin cancer. The primary cause of melanoma is ultraviolet light exposure in those with low levels of skin pigment. The UV light comes from the sun or other sources such as tanning devices. Using sunscreen and avoiding UV light can prevent melanoma. Sunscreen often comes in different levels measured in SPF (sun protection factor). But however, SPF does not measure how well a sunscreen will protect from UVA rays, which are also damaging and dangerous. SPF only measure sunscreen protection from UVB rays which are the kind that causes sunburn and contribute to skin cancer. Most people are not aware of what the SPF actually means. And with our device, we would not only protect people from melanoma but raise their awareness about which sunscreen factor one should use for that particular day at the precise place.
