100 days in Space!

The QB50 CubeSats deployed in May from the ISS are currently celebrating their first 100 days in Space.
Among the 28 CubeSats deployed from the ISS, 8 were initially thought to be dead on arrival. From them, 3 were finally brought back to life thanks to the radio amateur community. After a few days, an additional one went silent.

For most of the 22 "survivors", commissioning has proven to be challenging. 14 CubeSats are in the process of platform commissioning at various stages. 7 CubeSats are progressing in the sensor unit commissioning, and 1 is already producing valuable science data on a daily basis.

Among the 8 QB50 CubeSats launched by a PSLV rocket in late June, 1 has never been heard. 3 are progressing with the platform commissioning and 3 are commissioning the sensor unit. One IOD CubeSat has already successfully completed its mission: InflateSail deployed a dragsail and is expected to reenter in the atmosphere in the coming days.
