  • 你知道吗?每年11月28日是火星节,这是为了纪念“水手四号”(美国发射到金星、火星和水星附近的不载人航天探测飞船系列被称作“水手号”)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,因而让火星显的“红”了。

Red Planet Day honors ourcelestialneighbor, the fourth planet in the solar system.

    Is Mars truly red in color? Scientists debated this question, even after the Mars Rovers landed and began to explore the planet. Why? Because thelensesused to take photos are tinted4.

    On Red Planet Day, take a few minutes to look upwards5 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.
