Key points:

• It is launched from the Taiyuan Satellite Launch Center in the northern Shanxi Province.
• The satellite was launched by the Chinese Academy of Sciences (CAS) and developed by the International Research Center of Big Data for Sustainable Development Goals (CBAS).
• Guangmu was launched by a Long March-6 carrier rocket which is the 395th flight mission.
• Developed by the Chinese Academy of Sciences, the satellite (SDGSAT-1) is the world's first space science satellite dedicated to serving the UN 2030 Agenda for Sustainable Development.
• The satellite will observe interactions between human activities and nature.
• The satellite, with three optical payloads in it, can provide space observation data for monitoring, evaluating and studying the interaction between human and nature and sustainable development.

About 'Xihe' solar observation satellite:

• Recently, China also launched its first solar observation satellite.It was launched from the Taiyuan Satellite Launch Center in northern Shanxi Province aboard a Long March-2D rocket.
• The satellite was named as 'Xihe' (Xihe is the goddess of the sun who created the calendar in ancient Chinese mythology)
• China has sent its first solar exploration satellite into space from Taiyuan satellite launch centre.
• The satellite has been developed by the China Aerospace Science and Technology Corporation (CASC)
• Ten small satellites including an orbital atmospheric density detection experimental satellite and a commercial meteorological detection constellation experimental satellite were also sent into space using the same career rocket.
• The current launch marks the 391st flight mission of the Long March carrier rocket series.

The US space agency NASA has launched its first Lucy mission to study Jupiter's Trojan asteroids.

• The Lucy probe was launched on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida on October 16, 2021.
• Jupiter's Trojan asteroids are two large clusters of space rocks that scientists believe are remnants of the primordial material that formed the solar system's outer planets.
• The mission life of Lucy is 12-year, during which the spacecraft will fly by a total of eight ancient asteroids to study about solar system's evolution.

Why the name LUCY?

• There is a reason behind why NASA has named this mission as Lucy. In 1974, a human skeleton was found in Hadar, Ethiopia. After his study, scientists described him as the world's oldest human skeleton ever found. This skeleton was named Lucy (Australopithecine afarensis).
• To investigate Trojans on Jupiter, NASA has named its mission after the skeleton named Lucy. This spacecraft has gone out in search of fossils that are orbiting the Sun along with Jupiter, millions of kilometers from Earth.
