Goddard receives a grant of $ 3,500 from Clark University to continue rocket research. In a letter to the fund supervisor, he lays out his advanced concepts - Lox/LH2 liquid rockets, use of solar thermal and ion engines for interplanetary travel, constant-thrust 7.13 week trajectories to Mars. But publicly and practically, he continues his work on cartridge rockets.

Final test of cartridge rocket (a series of smokeless power cartridges, automatically loaded into a gun barrel and fired in sequence to produce thrust). Four of the five cartridges fire, but the fifth jams. The rocket only achieves 60 feet, the highest altitude to date.
