The replacement satellite, to be deployed this year, will be twice as long. Anetannas can operate behind wood, so a second antenna will be installed inside the satellite for use in case the exterior antenna does not unfold.

Japan built a micro-satellite (10x10x10 cm) with wood panel sides made of honoki magnolia. It was deployed from the International Space Station last year, successfully orbiting the Earth for 116 days, despite failing to make radio contact for unknown reasons. Perhaps its antenna did not unfold, or software did not load. A replacement will be deployed this year.

Newer PV is thinner, cracking easier, shortening lifespans, causing concern that multiple PV product generations will expire at the same time.
"Due to silicon cell cracking, Photovoltaic (PV) module reliability issues are gaining great attention due to the increasing demand for solar power and the reduction of cell thickness to reduce cost."
