LONDON: An image of the Ramadan crescent was captured by the Mohammed bin Rashid Space Center’s (MBRSC) remote sensing satellite DubaiSat-2 this week.

The image, released by MBRSC, was taken by rotating the earth observation satellite, a maneuver that took weeks of planning and hours of painstaking alignment.

Taken with a roll tilt angle of 0 degrees and roll pitch angle of 79.63 degrees, the final image was post-processed to highlight the crescent aspect of the moon.

DubaiSat-2 orbits Earth at a speed of 7.5 kilometers/ second, completing each total orbit of the planet in 90 minutes. Its camera images Earth from an altitude of some 600 kilometers at a resolution of 1 meter per pixel, providing world class images

The start of Ramadan is determined by the lunar calendar which follows a 29- or 30-day cycle determined by the cycle of the moon. Muslims anticipate the end of Shaaban, the month preceding Ramadan, by watching for the absence or presence of the crescent moon, which respectively indicates the continuation of Shaban or the beginning of Ramadan. 

Sighting of the Ramadan crescent can be achieved by three methods: through telescopes and binoculars; using astronomy; or viewing with the naked eye.
