With a weight of about 1,100 kilos, or 500 kilograms, the CAS 500 1 spacecraft has an optical digital camera designed to seize with a decision pretty much as good as 19.6 inches, 50 centimeters.

CAS stands for Compact Superior Satellite tv for pc.

In keeping with KARI, CAS500 1 is the primary satellite tv for pc in a fleet of a number of Earth-imaging observatories deliberate within the subsequent few years. The South Korean authorities led improvement of the CAS500 1 spacecraft, and KARI plans to switch the know-how to South Korean business to guide the development of a second satellite tv for pc named CAS500 2.

In a future part of the CAS500 program, South Korea plans to develop three satellites to watch agricultural and forest circumstances, monitor water assets, and help in catastrophe response efforts.

Extra burns by the Fregat higher stage will launch the opposite 37 satellites at totally different altitudes. All three sun-synchronous orbits focused by Saturday’s Soyuz mission might be between about 310 miles and 341 miles (500 to 550 kilometers) in altitude.

The second group of payloads will deploy from the Fregat higher stage starting round 4:35 a.m. EDT (0835 GMT), and the ultimate payloads are scheduled to separate from the rocket between 6:13 a.m. and 6:43 a.m. EDT (1013-1043 GMT), in line with Roscosmos.

“We might be doing three orbits, and separating a number of satellites,” Solodovnikov stated final month on the 2021 SmallSat Symposium. “The orbits might be at totally different altitudes. From a technical standpoint, it’s a really difficult, and on the identical thrillingly thrilling mission.”
