One of the biggest problems of launching satellites into space is the economic cost of escaping Earth's gravity. A factor that has already been significantly reduced thanks to the revolution of nanosatellites. However, to further reduce the cost of bringing a nanosatellite to an orbit of, for example, 600 kilometers, Bloostar He proposes an alternative.
The news of this project of the Spanish company zero2infinity, with headquarters in Catalonia and operational center in Cordoba, is that the complete video of the process has already appeared, which you can see in the header of this post. The idea is to raise the rocket that will transport the nano-satellite with a balloon at a height of 25 kilometers and, from there, allow the rocket to light and rise to 600 kilometers.
At that altitude, the density of the atmosphere is lower, and less fuel is required to overcome its resistance. The Bloostar rocket has three stages and is designed to orbit a maximum of 100 kilos of weight (75 if it is to a synchronous orbit with the Sun) with a volume of up to 2.4 cubic meters. All for a price of about 4 million dollars.
The tests will begin in 2016 and 2017 and commercial launches in 2018. Potential applications for the thousands of micro / nano satellites that will be launched by 2020 according to analyst forecasts, go through providing universal connectivity, or improving weather forecasts, or improving Earth observation with daily updated cartographies.
