All of the cumulative regions the wave passes through, with all of the growth and shrinkages that occur, imprint themselves onto the wave, as do the initial and final gravitational potentials.
The system also offers the potential for major cost reductions compared to other photoreforming approaches, as the reusable acid boosts hydrogen production rates.
Advocates warn the reductions could disrupt or cancel dozens of missions spanning planetary science, astrophysics and Earth observation — areas overseen by NASA's Science Mission Directorate.
