你应该知道11月份有个“感恩节”，或许也会想起那个有趣的“光棍节”。可你知道11月份还有个“火星节”吗？每年11月28日就是火星节！这个节日是为了纪念美国“水手四号”航天飞船的成功发射。1964年11月28日，美国发射了“水手四号”火星探测器，并首次从火星附近发回了第一批人类拍摄的火星照片。被称为“红星球”的火星真的是红色的吗？有科学家对此持有异议，其理由是：火星探测器在拍摄火星照片时使用了特定过滤镜头，因而让火星变“红”了。
Red Planet Day falls on November 28th every year. It commemorates[纪念] the launch of the Spacecraft Mariner 4 on November 28 th, 1964. (The 228 day mission of Mariner 4 brought the spacecraft within 6,118 miles of Mars on July 14 th, 1965. )
The planet Mars is referred to as the “Red Planet” because it appears red in color. Red Planet Day honors our celestial[天上的] neighbor, the fourth planet in the solar system.
Is Mars truly red in color? Scientists debated this question, even after the Mars Rovers[漫步者]
landed and began to explore the planet. Why? Because the lenses[镜头] used to take photos are tinted[给……着色].
On Red Planet Day, take a few minutes to look upwards into the sky, and gaze at our neighbor. Hopefully, you will have a cloudless night sky for viewing. You can also recognize this day by reading up about Mars, and viewing pictures of it. There are plenty of pictures online to which you can get an easy access.
