This idea shows how being car-free can lower stress levels               The author suggest that studying venus is a worthy pursuit because, venuse have been the most like earth planet in our solar system. they belive that long ago venus was probably coverd with large oceans and could have supported various forms of life, just like earth."venus can sometimes be a nearest option for a planetary visit, a crucial consideration given the long time frames of space travel". NASA has been thinking of many ideas to help humans explore venus, possible solution to the hostile condition on the surface of venus would allow scientist to float above the fray of venus. bump like vehical hovering over 30 or so miles above the roiling venusian landscape. like a jet airplane travel at ahigher altitude to fly over many storms, a vehicle hovering over venus would avoid the deadly ground conditions by staying up and out of the their way. researchers are working on innovations that would allow our machines to last long enough to contribute meaningfully to our knowledge of venus.
