Otherwise called CubeSat, the popularity of smaller spacecraft highlights the need for better conscious on reducing the number of space junk floating around the Earth’s orbit. Some of the concerns for addressing the problem include risks to astronauts’ safety.
GPS and CRPA simulation systems will be more important because more companies are planning to launch new small satellites into space.
Almost 900 small satellites went into orbit in the last 10 years, and better productivity and cost efficiency are some of the driving factors for this rising number. Some companies prefer building satellites the size of a bread loaf instead of traditional satellites that cost more.
In terms of operational efficiency, a single satellite could only transmit data once every three days. Smaller satellites could do this more frequently at least once every 10 minutes. It’s not surprising then that the faster turnaround makes small satellites an ideal alternative for several purposes, including weather forecasts, land mapping and disaster response.
The use of smaller spacecraft could also solve the problem with the increasing volume of space garbage. It generally costs more to retrieve broken parts, decommissioned satellites, and other debris back to Earth, than simply launching one into space.
However, their proper disposal remains a necessity because of the inherent risks not just for astronauts. There are around 1,800 active satellites today and those that are no longer functional either gravitate back to Earth or simply collide with other existing junk. The second scenario is less ideal since it only creates more trash that adopts their own orbit in space.
Small satellites have become more prominent in recent years, although it would still require developers to adopt better simulation technology. This will allow them to foresee any problems, particularly on its security capabilities, prior to their actual use.
