Methods For Slow Manned Missions
Slow interstellar travel designs such as Project Longshot generally use near-future propulsion technologies. As a result, voyages are extremely long and risky, starting from about one hundred years and reaching to thousands of years. Crewed voyages (speculative) might be one-way trips to set up colonies.
Nevertheless, serious if preliminary discussions are taking root for the ~100 year time scale, with trials of the MMSEV/Nautilus-X concept preliminary to asteroid exploration in preparation.
The duration of a slow interstellar journey presents a major obstacle. The following are some proposed solutions:

Famous quotes containing the words methods, slow and/or missions:
“With a generous endowment of motherhood provided by legislation, with all laws against voluntary motherhood and education in its methods repealed, with the feminist ideal of education accepted in home and school, and with all special barriers removed in every field of human activity, there is no reason why woman should not become almost a human thing. It will be time enough then to consider whether she has a soul.”
—Crystal Eastman (1881–1928)
“He has outsoared the shadow of our night;
Envy and calumny and hate and pain,
And that unrest which men miscall delight,
Can touch him not and torture not again;
From the contagion of the world’s slow stain
He is secure, and now can never mourn
A heart grown cold, a head grown grey in vain.”
—Percy Bysshe Shelley (1792–1822)
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
