%X When a satellite is in orbit, it remains in direct contact with a hostile environment. An analyzes of possible failures that have occurred with CubeSat class satellites due to this exposure is presented. These small satellites have 10cm cubic form and about 1.33 kilograms, they have all subsystems integrated on a single module that ts in the available intern volume, using high technology of miniaturization. Generally, this satellites are launched at a 650km (LEO) altitude orbits. At this range, one of the biggest problems that may aect satellites is the precipitation of charged particles, and this may cause the failure of subsystems and magnetic interference in equipments, with emphasis to natural causes as the impact of solar activity (the solar cycle, solar  ares, coronal mass ejection, etc.) and the interference of the South Atlantic Magnetic Anomaly, knowing that the majority of CubeSat's orbits intersect at some point the acting anomaly region. The analysis consist of a statistical survey of thirty nine CubeSats already launched, taking into account their actual conditions, giving results of the most common causes and issues that have occurred with them, including the relationship with larger satellites of all kinds, thus contributing for the success and optimization of future CubeSats missions.
