CAPE CANAVERAL, Fla. (AP) — NASA is underestimating the amount of time and money it will take to bring Mars rocks back to Earth in the coming decade, an independent panel said Tuesday.

The review board suggested that NASA and the European Space Agency consider bumping the next launches in the sample-return effort from 2026 to 2028, given all the technological challenges. These delays will increase costs, pushing the planning budget to $4 billion or more — $1 billion more than currently envisioned by NASA, the panel noted.
