A handy attachment could make lunar construction a breeze

Moving large amounts of regolith is a requirement for any long-term mission to the moon or Mars. But so far, humanity has only sent systems capable of moving small amounts of soil at a time—primarily for sample collection. Sending a large, dedicated excavator to perform such work might be cost-prohibitive due to its weight, so why not send a bulldozer attachment to a mobility unit already planned for use on the surface?
