KickSat

Due to a non-redundant design, a timer reset while on-orbit and the femtosatellites were not deployed in time, and burned up inside the KickSat mothership when the undeployed satellite-deployment mechanism reentered Earth's atmosphere.

[11][12][13][14] In its minimal configuration, each Sprite femtosatellite will be designed to send a very short message (a few bytes long) to a network of ground stations.

[18] KickSat launched on an ISS commercial resupply mission, SpaceX CRS-3, originally scheduled for late 2013,[4] but ultimately delayed until April 18, 2014.

[19] On April 30, 2014, the microcontroller managing the master clock was found to have reset due to a technical problem, an effect of space radiation.

This verified the design could survive the space environment for far longer than the planned nominal mission length.

[26] KickSat-2 established communication with ground controllers soon after, reporting good health despite a weaker than expected signal.
