Goddard's work lays out the concept of using the multi-stage rocket for exploration of outer space and reaching the lunar surface. It spawns a nightmare of media interest and derision, making Goddard even more secretive of his dreams for space flight. References: 377 .

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. References: 377 .
