China's Mars probe Tianwen-1 has traveled 155 million km, according to Zhang Rongqiao, chief designer of China's first Mars exploration mission.

As of 8:30 a.m. on Friday, the probe was in stable condition at a distance of more than 18 million km away from Earth, Zhang said at the ongoing 2020 China Space Conference held in Fuzhou, capital of east China's Fujian Province.

The probe has successfully captured a photo of Earth and the moon, and completed its first mid-course orbital correction and self-check on multiple payloads, Zhang added.

China launched the Mars probe on July 23, kicking off the country's independent planetary exploration mission. The spacecraft, consisting of an orbiter, a lander, and a rover, is expected to reach the red planet around February 2021.

The expected touchdown date is May 2021, about three months after Tianwen-1 arrives in the Mars orbit.

"Reaching Mars' gravitational field and landing on the planet remain the major difficulties, with all kinds of potential risks," Zhang said, adding that the engineering team is still fine-tuning the probe's flight control and preliminary restoration schemes.

The oldest known animal sperm in the world has been discovered by a team of Chinese paleontologists along with their counterparts from Germany and Britain, reports Xinhua.

The sperm came from a species of crustacean named ostracod, sometimes known as “seed shrimp”- widely distributed in oceans, lakes, swamps, rivers and ponds.

The researchers discovered the ostracod sperm in a piece of amber dating 100 million years ago in Myanmar, according to the Nanjing Institute of Geology and Palaeontology affiliated to the Chinese Academy of Sciences. It weighs 0.676 gram and contains 39 ostracod specimens.

In a published paper on the Proceedings of the Royal Society B: Biological Sciences, the researchers stated that the ancient ostracod could produce giant sperms and engaged in sexual reproduction just like its present-day offspring. In spite of being more than one-third of the animal's body length, the ancient ostracod sperm bears a close resemblance to its modern forms.

"Huge sperm can effectively improve the success rate of mating, which may be an important reason for the large ostracod populations," said Wang He, a member of the research team and a researcher with the institute in Nanjing. Before this latest discovery, the oldest confirmed animal sperm dated to about 50 million years ago.
