Towards long-term permanence on the Moon: NASA historic Artemis mission to set off on August 29

Almost 50 years after the last Apollo mission ventured to the lunar surface, NASA has established the Artemis program, which has the ultimate goal of establishing a long-term presence on the Moon’s surface. With a long-term presence established on or around the Moon, it would then be used for future missions further afield, including to Mars - and it all begins with Artemis I. All of the objectives for the inaugural Artemis flight will demonstrate capabilities necessary for when the Orion spacecraft carries humans to deep space. The list includes an overall safe flight, the performance of the rocket, testing the heat shield and retrieving the spacecraft. Artemis I is officially a test flight where new technologies will be tested without crew onboard. After Artemis I comes Artemis 2 and 3, NASA’s first manned lunar missions in five decades. Artemis 3 will be the first crewed lunar landing since Apollo 17 in 1972. It is also intended to be the first mission to land a woman on the Moon. After the discovery in 2009 of Lunar pits and caves that could provide Earth-like temperatures (17 degrees Celsius, 63 Fahrenheit) long term permanence on the Moon’s surface may not be too far away. These pit craters, and the caves to which they may potentially lead, would make safer, more thermally stable base camps for lunar exploration and long-term habitation than the rest of the Moon’s surface, which heats up to 260 degrees (126.6 Celsius) during the day and drops to 280 degrees below zero at night (-173.3 Celsius).

15 years of negotiations not enough for UN international treaty to preserve Earth’s oceans biodiversity

It is a scientific fact that human life depends on oceans and their biodiversity. In the last decades an incredible number of species in the sea have reduced in number so much that they are now at risk of extinction. A study published in Science found that under business-as-usual global temperature increases, marine systems are likely to experience mass extinctions on par with past great extinctions. Protecting the biodiversity that has been created in the seas in the last 50 million years is now a critical and urgent global matter. Yet, a fifth round of negotiations for a UN ocean treaty to protect and manage the high seas failed to reach an agreement on Friday in New York. The negotiations focused on four key areas: (1) Establishing marine protected areas for more than 30% of the earth’s surface; (2) Improving environmental impact assessments; (3) Providing finance and capacity building to developing countries; (4) Sharing of marine genetic resources - biological material from plants and animals in the ocean that can have benefits for society, such as pharmaceuticals, industrial processes and food. Laura Meller, who leads Greenpeace’s ocean protection campaign, accused rich countries such as the United States of being too slow to compromise. “Russia has also been a key blocker in negotiations, refusing to engage in the treaty process itself, or attempting to compromise with the European Union and many other states on a wide range of issues,” Meller said. The talks will resume next year unless a special emergency session is called before the end of 2022. One of the most sensitive issues revolves around the sharing of possible profits gained from developing genetic resources in international waters, where pharmaceutical, chemical and cosmetic companies hope to find miracle drugs, products or cures. Such costly research at sea is largely the prerogative of rich nations, but developing countries do not want to be left out of potential windfall profits drawn from marine resources that belong to no one. Similar issues of equity between the Global North and South arise in other international negotiations, such as on climate change, where developing nations feel outsized harms from global warming and try in vain to get wealthier nations to help pay to offset those impacts. Economic differences between nations are hindering developments that are more and more urgent for our species’ future survival.

Unprecedented heatwave continues in China

The world's second-largest economy has experienced over 70 days of heatwaves, flash floods and droughts - phenomena that scientists say are becoming more frequent and intense due to climate change. Dazhou, a city that is home to more than 5.3 million people in the Southwest, has seen particularly high temperatures. The heat reached up to 43 degrees Celsius on Tuesday, the highest on local meteorological records since 1953. The extreme weather is also testing Dazhou’s power generation capacity. Some counties and rural areas have suffered prolonged and irregular power outages, which has affected both the lives of local residents and business production. Power shortages have been a problem for many areas across the country recently, notably in Sichuan and its neighbouring city Chongqing due to the extremely hot weather. Reports of extreme conditions also came from Chinese social networks: due to 40 reported Covid cases, in Chongqing authorities ordered more than 10 million people in the city's central urban districts to undergo mandatory tests. The highest temperature in Chongqing soared past 40 degrees Celsius (104 degrees Fahrenheit) and some posted their exasperation during the long waiting in the queues. The regions affected by such extreme conditions also happen to be major grain-producing areas that satisfy a substantial percentage of the yearly need (more than 25%). The rapid expansion of drought, combined with heat waves, poses a serious threat to autumn grain harvest - the Ministry of Agriculture said on Tuesday. The Chinese government is continuously allocating more funds to support autumn harvest and help drought relief that is threatening crop growth.

Dugong is declared extinct in China

Known as the ocean's most gentle giant, the dugong is a unique character of the sea. Weighing in at almost half a tonne and it is the only vegetarian marine mammal. Scientists at Zoological Society of London (ZSL) and the Chinese Academy of Science reviewed all historical data on where dugongs had previously been found in China. They found there had been no verified sightings by scientists since 2000. Moreover, the researchers turned to citizen science to interview 788 community members living in those coastal regions identified, residents reported not having seen a dugong for 23 years. Only three people had seen one in the past five years. Researchers concluded that this beautiful mammal, related to the manatee and inspiration of the ancient tales of mermaids and sirens, is now irreversibly extinct in China. It still exists elsewhere in the world but it is a vulnerable species as defined by WWF. Dugongs are threatened by sea grass habitat loss or degradation because of coastal development or industrial activities that cause water pollution.  If there is not enough sea grass to eat then the dugong does not breed normally. This makes the conservation of their shallow water marine habitat very important. They also often become victims of bycatch, the accidental entanglement in fishing nets.

More than 5000 farmers protest against Modi in New Delhi

Farmer’s protests in India are causing public security issues throughout the country. This Monday farmers organizations have once again taken to the streets in protests and called for a 'mahapanchayat' (public meeting) at Jantar Mantar in the national capital New Delhi. Despite the national guard was preparing since days to the event, more than 5000 protesters broke barricades with banners and flags and marched through the streets shouting anti-Modi government slogans. They demanded president Modi take the actions he announced last November, when he said he would repeal three farm laws aimed at agricultural deregulation. Farmers claim the laws allow big companies to exploit them and demand a law guaranteeing minimum price on their crops. The protesters were also demanding the release of a group of farmers who were arrested by the police last year in connection with farmers’ agitation.
