spacecraft to navigate through space and reach the Didymos asteroid system. The flexible and rollable modular wings are lighter, more compact and stiffer in space and smaller than iROSA. Each array will slowly unfurl to reach 28 feet (8.53 m) in length. DART will be the first probe to fly the new arrays, paving the way for their use on future missions. Redwire delivered ROSA to APL in May 2021 and worked closely with the APL team for some weeks to carefully install them onto the spacecraft. The installation was completed on 13 August 2021. A small portion of each DART solar array is configured to demonstrate Transformational Solar Array technology, which has very-high-efficiency SolAero Inverted Metamorphic Multijunction (IMM) solar cells and reflective concentrators providing three times more power than current solar array technology.
