China’s lunar probe detects in-situ moon surface water

Chinese scientists published results of in-situ detection of water signals on the moon by the Chang’e-5 lunar lander, lending new evidence to the dryness of the satellite.

The study published on Saturday in the peer-reviewed journal Science Advances revealed that the lunar soil at the landing site contains less than 120 parts per million water or 120 grams of water per tonne, and a light, vesicular rock carries 180 parts per million, which are much drier than that on Earth.

A device onboard the lunar lander measured the spectral reflectance of the regolith and the rock and detected water on the spot for the first time.

The water content can be estimated since the water molecule or hydroxyl absorbs at a frequency of about three micrometers, according to researchers from the Chinese Academy of Sciences (CAS).

It was the solar wind that contributed to the most humidity of lunar soil, as it brought hydrogen that makes up the water, the researchers said.

The additional 60 parts per million water in the rock may originate from the lunar interior, according to the researchers.

Therefore, the rock is estimated to hail from an older, more humid basaltic unit before being ejected onto the landing site to be picked up by the lunar lander.

The study revealed that the moon had turned drier within a certain period, owing probably to the degassing of its mantle reservoir.

The Chang’e-5 spacecraft landed on one of the youngest mare basalts located at a mid-high latitude on the moon. It measured water on the spot and retrieved samples weighing 1,731 grams.

“The returned samples are a mixture of granules both on the surface and beneath,” Lin Honglei, a researcher with the Institute of Geology and Geophysics under CAS, told Xinhua. “But an in-situ probe can measure the outermost layer of the lunar surface.”

Lin also said that to simulate authentic lunar surface conditions on Earth is challenging, thus making the in-situ measurement so essential.

The results are consistent with a preliminary analysis of the returned Chang’e-5 samples, according to the study.

The findings provide more clues to China’s Chang’e-6 and Chang’e-7 missions. The investigations of lunar water reserves come into the limelight as the building of manned lunar stations are in the pipeline in the next decades.

England has lifted its restrictions implemented in the wake of the COVID-19 pandemic. Speaking at a press conference at Downing Street, Health Secretary Sajid Javad stated that the England will be lifting the restrictions implemented in wake of the COVID-19 pandemic but the legal requirement to self-isolate if tested positive for the virus will continue.

While Health Secretary Sajid Javad stated that it was a major milestone, he also stated that “It’s not the end of the road and we shouldn’t see this as the finish line because we cannot eradicate this virus and its future variants. Instead we must learn to live with Covid in the same way we have to live with flu”.

This has also meant that the work-from-home guidance would be ending with the majority of the nation’s workforce reverting to pre-pandemic work schedules. Additionally, students will also be no longer required to wear masks at schools.

Moreover, Prime Minister Boris Johnson has also confirmed that the Government plans to end the legal requirement for positive cases to isolate by late March, but may move the date forward.

The U.S. has also hinted that the pandemic may be heading towards an end. Chief Medical Advisor to the President of the United States, Dr. Anthony Fauci has stated that the Omicron variant may mark the end of the pandemic.

China’s self-developed C919 large passenger aircraft will be delivered within this year, The Paper reported on Wednesday, citing its developer.

Wu Yongliang, deputy general manager of the Shanghai-based Commercial Aircraft Corporation of China (COMAC), said the pandemic’s impact on the C919 project has been controllable, and the work is progressing in an orderly manner.

American aerospace manufacturer Boeing and France-based Airbus have long been the so-called duopoly in the commercial airline market worth trillions of U.S. dollars.

The C919, as part of China’s goal to develop homemade civil airplanes, is trying to rival with medium-range aircraft from the two global giants, such as Airbus’s A320 and Boeing’s 737 MAX.

C919 has 158 to 168 seats, a standard range of 4,075 kilometers and a maximum range of 5,555 kilometers. It had its successful maiden flight in 2017.

China Eastern Airlines, one of the country’s largest airlines also headquartered in Shanghai, signed a contract to buy five C919 jetliners from COMAC in March 2021.
