The US space agency NASA has released a new video which shows Moon crossing the sunlit side of the Earth. The video was made by stitching the images captured by the Deep Space Climate Observatory (DSCOVR) launched jointly by NASA and NOAA.
It is for the second time that moon came between the satellite and the sunlit side of the Earth. The second appearance was captured on July 5 this year. “For the second time in the life of DSCOVR, the moon moved between the spacecraft and Earth,” said Adam Szabo, a DSCOVR project scientist at NASA’s Goddard Space Flight Center in a press release. “The project recorded this event on July 5 with the same cadence and spatial resolution as the first ‘lunar photobomb’ of last year.”
Three images were captured using the Earth Polychromatic Imaging Camera (EPIC) installed on the DSCOVR satellite. The satellite also contains four-megapixel charge coupled device (CCD) camera and a telescope which aid scientists in making precise observations.
“Combining three images taken about 30 seconds apart as the moon moves produces a slight but noticeable camera artifact on the right side of the moon. Because the moon has moved in relation to Earth between the time the first (red) and last (green) exposures were made, a thin green offset appears on the right side of the moon when the three exposures are combined. This natural lunar movement also produces a slight red and blue offset on the left side of the moon in these unaltered images,” said NASA in a statement.
In the video, we can see moon moving over the Pacific Ocean and then it crosses the Indian Ocean while moving towards the North Pole. Previously, EPIC captured similar event on July 16, 2015. It was also the first time when moon interveined direct view of the sunlit side of Earth and the satellite DSCOVR.
Deep Space Climate Observatory(DSCOVR; formerly known as Triana, unofficially known asGoreSat) is a NOAA Earth observation and space weather satellite launched by SpaceX on a Falcon 9 launch vehicle on February 11, 2015 from Cape Canaveral. It was originally developed as a NASA satellite proposed in 1998. The 570 kg satellite orbits Earth at a height of 1,500,000 km.
Moon crosses the elliptical orbit of the satellite four times a year but the event of crossing the sunlit Earth occurs only once.
