Mightysat-2 (P99-1)

Mightysat 2.1 [Spectrum Astro]

Mightysat 2.1 (meaning first flight of the series-2 version) is an military minisatellite to test / demonstrate components for future utilization. The 130 kg spacecraft carries two kinds of hardware for tests. In the list of "unproven technologies" are:

• SAC which focuses solar energy on solar cells;
• NSX that is an ultra-light weight communications unit; and
• MFCBS that contains a multifunctional composite bus structure.

In the list of "stand alone experiments" are:

• FTHSI that provides hyperspectral images through a Fourier transform technique;
• QS40 that monitors radiation damage in microelectronic components;
• SMATTE to investigate the bimodal behavior of composite sheets that change physical properties such as stiffness by tailored thermal inputs but can recover to the original status after heating above a transition temperature; and
• SAFI that carries embedded copper wires in a composite film to help reduce the weight of components.

Four more satellites in The MightySat-2 series were planned, but were finally cancelled.
