The text reads:
Engineer Jorge Lassig, director of the Penhuesat Uncoma project informed
that the satellite takes between 48 and 72 hours to charge its batteries,
due to the inadequate position of the cone to which it is still attached in
reference to the sun. Once the batteries are recovered, the sat transmits
during several orbits until they discharge again. At that moment, the
onboard computer sets the system in safe mode, leaving just the oscillator
on. Folks at Uncoma are evaluating when the cone will change its position
in space, to benefit the battery charging process of Penhuesat (the cone has
no attitude control). More info to follow. Regards, Ignacio Mazzitelli
