The China National Space Administration (CNSA) published Tuesday the first images captured by the newly launched CBERS-4 satellite jointly¹ developed with Brazil.

中国国家航天局周二发布了新发射的CBERS-4号卫星拍摄的首批照片，该卫星由中国与巴西共同研制开发。

The images, captured with 5m panchromatic/8m multispectral cameras, are "clear, colorful and with high quality and have met the designed standards," according the CNSA.

China launched the CBERS-4, the fifth satellite of the Chinese-Brazilian Earth Resource Satellite (CBERS) program, from the Taiyuan satellite launch center in northern Shanxi Province Sunday.

The program was initiated² in 1988. Such satellites are mainly used for the monitoring, planning and management of land, forestry³, water conservation, environmental protection and agriculture.

The first satellite of the program, CBERS-1, was launched in 1999 with the second and third, CBERS-2 and CBERS-2B, launched in 2003 and 2007.

CBERS-3 was launched last December from Taiyuan but failed to enter orbit after the rocket malfunctioned⁴.

The Chinese and Brazilian space mission authorities also signed a letter of intent for following satellite cooperation Tuesday.

The two nations agreed to build CBERS-4A, which is expected to be launched around 2017.
