<prompt> Hlalosa lintlha tse tharo tsa sehlooho sehloohong se fanoeng.  <response>: Instruction in English: Identify the three main points in the given article. . Response in English: After reading through the article, here are the three main points:1. traveling in space might not necessarily have an impact on human aging, but the long-term effects of deep-space exploration e.g., radiation, still pose a challenge to astronauts.2. time dilation, a component of Einsteins theory of general relativity, suggests that time would run slower for astronauts travelling near the speed of light. But, this would only be perceptible if the journey takes place over a much greater distance than our solar system.3. Furthermore, due to the vast distances and current propulsion technology limitations time required to travel to deep space, is still a limiting factor to meaningful time dilation experiments. . Response in Sesotho: Ka mora ho bala sehlooho sena, lintlha tse tharo tse kholo ke tsena: 1. ho tsamaea sebakeng ho ka na ha se ke ha e-ba le tšusumetso botsofaling ba motho, empa liphello tsa nako e telele tsa ho hlahloba sebaka se tebileng mohlala, mahlaseli a kotsi a ntse a hlahisa bothata ho bo-ra-astronote. 2. katoloso ea nako, e leng karolo ea khopolo ea Einstein ea kamano e akaretsang, e fana ka maikutlo a hore nako e ne e tla tsamaea butle bakeng sa bo-ramahlale ba tsamaeang haufi le lebelo la khanya. Empa, sena se ka bonahala feela haeba leeto le nka sebaka se selelele ho feta setsi sa rona sa lipolanete. 3. Ho feta moo, ka lebaka la bohole bo boholo le mefokolo ea morao-rao ea thekenoloji ea propulsion nako e hlokahalang ho ea sebakeng se tebileng, e ntse e le ntlha e lekanyelitsoeng litekong tse nang le morero tsa ho atolosa nako.
