=== Slow, uncrewed probes ===
{{Main|Interstellar probe}}
"Slow" interstellar missions (still fast by other standards) based on current and near-future propulsion technologies are associated with trip times starting from about several decades to thousands of years. These missions consist of sending a robotic probe to a nearby star for exploration, similar to interplanetary probes like those used in the [[Voyager program]].<ref>{{cite book|title=Voyager|date=1977|publisher=ERIC Clearing House|location=Louisiana State University|page=12|url=http://eds.a.ebscohost.com.libezp.lib.lsu.edu/eds/detail/detail?vid=5&sid=76390b8e-3776-42f2-87d0-14f9ce6435e2%40sessionmgr4001&hid=4210&bdata=JnNpdGU9ZWRzLWxpdmUmc2NvcGU9c2l0ZQ%3d%3d#AN=lalu.2943532&db=cat00252a|access-date=2015-10-26}}</ref> By taking along no crew, the cost and complexity of the mission is significantly reduced, as is the mass that needs to be accelerated, although technology lifetime is still a significant issue next to obtaining a reasonable speed of travel.
