                    6.4 CONCLUSION

                    Given launch costs ranging from approximately $10,000/pound for LEO to as much
                    as $1M/pound for deep space missions, there is no question that the high degree
                    miniaturization afforded by MNT-based devices and systems is key to enabling
                    the faster, better, and cheaper missions of tomorrow. Although there exists a
                    large diversity of space-related applications, there is an equally large diversity of
                    MNT, thus ensuring that nearly every MNT-based solution is guaranteed to find a
                    home in future space missions. However, the infamous ‘‘mid-TRL gap’’ represents
                    the single biggest obstacle to the infusion of a much broader range of micro- and
                    nanotechnologies, than the lucky few that have been selected to date. For
                    rapid and cost-effective infusion of MNT into space applications, a coordinated
                    technology development approach, via a TMT-like mechanism proposed above, is
                    essential. Furthermore, cheap and rapid access to space testing via novel spacecraft
                    platforms such as the PICOSAT or CubeSats will ensure that the ‘‘infant mortality’’
                    rate of MNT remains low.
