Space travel for tourists might become reality one day. On Oct 13, Blue Origin, the rocket company established by Amazon founder Jeff Bezos, launched its vehicle, New Shepard, to the edge of Earth’s atmosphere (大气层). This was the first test flight in nearly a year, but the 13th test flight for the program overall. Though New Shepard has yet to fly with humans on board, the goal is to one day fly paying customers to and from suborbital (亚轨道的) space. So far, the rocket has carried out experiments for NASA, including testing a sensor (传感器) that might help achieve more precise (精确的) landings on the moon.
