MEXICO: It has been reported that a NASA camera on the Deep Space Climate Observatory satellite has captured view of the sunlit side of Earth from one million miles away. NASA released the image on Monday. Exactly 46 years ago man achieved a big milestone of first landing on the moon.
Editor Karen Northon wrote on NASA’s website, “This color image of Earth was taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope. The image was generated by combining three separate images to create a photographic-quality image”.
Northon added that the camera captures a series of 10 images by making use of different narrowband filters, right from ultraviolet to near infrared, in order to produce different science products and these color images use the red, green and blue channel images.
Buzz Aldrin wrote about significance of this technology for the future of space travel in a blog post. According to him, DSCOVR has come up with a vantage point view of the planet, in addition to helping in a neighborhood watch program that searches for harmful solar activity.
The image was captured on July 6, 2015, and it shows North and Central America. Shallow seas surrounding the Caribbean islands are the central turquoise areas.
According to Northon, the Earth image is showing the impacts of sunlight scattered by air molecules, and as a result of it, the image has a characteristic bluish tint. The EPIC team is making efforts to remove this atmospheric effect from the images.
