Without more specific context, it is difficult to provide an answer to this question as it is not clear who Marsha is or what space travel experience she had.
However, generally speaking, space travel has been known to have a profound impact on people's perspectives and outlooks on life.
For example, seeing Earth from space has been described as a transformative experience that can lead to a greater appreciation for the fragility and interconnectedness of our planet and its inhabitants. Astronauts who have spent time in space have reported feeling a profound sense of awe and wonder, as well as a heightened awareness of the beauty and diversity of the universe.
Additionally, space travel often requires individuals to undergo rigorous physical and mental training, as well as work closely with a diverse group of people from different backgrounds and cultures. These experiences can lead to personal growth and development, as well as a greater sense of empathy and understanding towards others.
In summary, while we cannot speak to Marsha's specific experience, space travel has the potential to shape individuals in profound and transformative ways, both in terms of their outlook on life and their personal growth and development.
