United Arab Emirates Astronaut Hazzaa Al Mansoori | NASA Portrait

Hazza Al Mansoori is an Emirati astronaut and was the first person from the United Arab Emirates (UAE) in space. In 2019, he embarked on the UAE's first scientific mission to the International Space Station (ISS). The mission slogan was 'Zayed's Ambition', making the UAE the 19th country worldwide, and the first country in the Arab region, to travel to the International Space Station.  Mansoori was assigned to the Roscosmos Soyuz MS-15 spacecraft, alongside Russian commander Oleg Skripochka and American flight engineer Jessica Meir of NASA. They launched to the International Space Station on September 25, 2019. In this picture, Mansouri is wearing the extravehicular mobility unit (EMU) spacesuit used for extravehicular activities (EVAs) or spacewalks.

The Extravehicular Mobility Unit (EMU) is an independent anthropomorphic spacesuit that provides environmental protection, mobility, life support, and communications for astronauts performing extravehicular activity (EVA) in Earth orbit. Introduced in 1981, it is a two-piece semi-rigid suit, and is currently one of two types of EVA spacesuits used by crew members on the International Space Station (ISS), the other being the Russian Orlan space suit.

China-European Space Agency Science Mission: Einstein Probe’s First X-ray Images

China-European Space Agency Science Mission: Einstein Probe’s First X-ray Images

The first images captured by the Einstein Probe (爱因斯坦探针) were revealed during the 7th Joint Workshop of the Einstein Probe Consortium, held in Beijing, China, from April 24 to 26, 2024. The Einstein Probe (爱因斯坦探针) is a collaboration led by the Chinese Academy of Sciences (CAS) with the European Space Agency (ESA) and the Max Planck Institute for Extraterrestrial Physics (MPE), Germany. 

The Einstein Probe is equipped with a new generation of X-ray instruments with high sensitivity and a very wide view, designed to observe powerful blasts of X-ray light coming from neutron stars and black holes. China launched the X-ray satellite Einstein Probe (EP) on January 9, 2024. It will help scientists further unlock valuable information about the universe by observing distant flashes from cosmic events.

"The Einstein Probe can capture sudden cosmic burst events, or violent activities of celestial bodies. This kind of celestial body that suddenly appears in the universe, lasts for a few moments, and then disappears quickly is called a transient," said Yuan Weimin, chief scientist of the Einstein Probe.

There are many spectacular transients and bursts in the universe from stellar activities near the solar system to gamma ray bursts from the distant early universe. They can generate huge radioactive energy in a very short period of time, concentrated in the X-ray band, producing complex and changing brightness levels like sparkling fireworks. Such transients and bursts originate from the critical stages of the formation and evolution of celestial bodies, and carry key information for studying the universe. However, due to absorption by the Earth's atmosphere, X-rays containing valuable information cannot reach the ground.

"These transients are relatively far away, and their signals are relatively dim. They appear randomly in space. We don't know when and in what direction they appear. So it is difficult for current satellites to detect them, and we need a monitor with very high sensitivity and large field-of-view. That's why we developed the Einstein Probe—to capture these more remote and dimmer transients and bursts," Yuan said.

Ceremony: Shenzhou-17 Crew Ready for Earth Return | China Space Station

The Shenzhou-17 astronauts handed over control of the Tiangong space station to the newly arrived Shenzhou-18 crew on Sunday, April 28, 2024, and are ready to return to Earth, said the China Manned Space Agency.

The three Shenzhou-17 astronauts have completed all set tasks for their six-month stay in space.

At around 15:00 (Beijing Time), the two crews held a handover ceremony, with Shenzhou-17 astronauts Tang Hongbo, Tang Shengjie and Jiang Xinlin, and Shenzhou-18 astronauts Ye Guangfu, Li Cong, and Li Guangsu signing their names on handover confirmation documents.

"I hereby pass the hatch key symbolizing the baton to you. Starting from now, you officially take over the operation and management of the space station," said Tang, mission commander of the Shenzhou-17 crew.

"Alright. We, the crew of Shenzhou 18, will surely do our utmost to run our leg of this space relay of the Shenzhou family," said Ye, mission commander of the Shenzhou-18 crew.

The Shenzhou-17 crew are due to return to Earth on Tuesday, April 30, 2024, aboard the Shenzhou-17 spaceship.

The Dongfeng Landing Site in north China's Inner Mongolia Autonomous Region is now preparing for the return of Shenzhou-17 from space.

Space Environment Simulation Laboratory | NASA's Johnson Space Center

Space Environment Simulation Laboratory | NASA's Johnson Space Center

This is Building 32, Chamber A at NASA's Johnson Space Center in Texas. After it was constructed in 1965, the Space Environment Simulation Laboratory (SESL) tested all Apollo command and service modules, Apollo lunar modules, spacesuits for extra-vehicular activity, the Skylab/Apollo telescope mount system, Space Shuttle systems, the Apollo/Soyuz docking module and various large scale scientific satellite systems, such as the parabolic reflector subsystem of the Applications Technology Satellite. The thermal vacuum testing done at the SESL since 1965 has been a significant factor contributing to the success of both the crewed and uncrewed space program of the United States.

Johnson Space Center’s Chamber A is a 16.8 m (55 ft) diameter x 27.4 m (90 ft) high, thermal-vacuum test facility and is famous for testing the Apollo spacecraft, with and without the mission crew. Its usable test volume and high-fidelity space simulation capabilities are adaptable for thermal-vacuum testing of a wide variety of test articles, including entire space vehicles. Test articles are normally inserted into the chamber by means of a precision, mobile crane. The dual crew-locks, when configured for human testing, provide a means for the test crew to move from ambient air pressure to the thermal-vacuum environment and back. They also provide for the maintenance of rescue personnel at convenient intermediate pressures during crew test operations. When the inner door is bolted, either of the crew-locks can be used as an altitude chamber for independent tests.

Additional test support equipment includes mass spectrometers, infrared cameras and television cameras. The numerous flanges at all levels provide ample pass-throughs for electrical, instrumentation and gasses to support large systems.

Chamber A was upgraded to support the James Webb Space Telescope test program. Additions involved an ultra-clean hydrocarbon-free high vacuum pumping systems and the ability to simulate the extremely low temperatures of deep space (35K) within a 45 foot diameter by 80 foot tall shroud volume. The chamber systems are now able to maintain class 10,000 clean room conditions for ambient operations.

Regulus Star & Dwarf Galaxy Leo I

Regulus Star & Dwarf Galaxy Leo I

In northern hemisphere spring, bright star Regulus is easy to spot above the eastern horizon. The alpha star of the constellation Leo, Regulus is the spiky star centered in this telescopic field of view. A mere 79 light-years distant, Regulus is a hot, rapidly spinning star that is known to be part of a multiple star system. Not quite lost in the glare, the fuzzy patch just below Regulus is diffuse starlight from small galaxy Leo I. 

Leo I is a dwarf spheroidal galaxy, a member of the Local Group of galaxies dominated by our Milky Way Galaxy and the Andromeda Galaxy (M31). About 800 thousand light-years away, Leo I is thought to be the most distant of the known small satellite galaxies orbiting the Milky Way. But dwarf galaxy Leo I has shown evidence of a supermassive black hole at its center, comparable in mass to the black hole at the center of the Milky Way.

China Unveils Latest Progress on Moon Exploration Projects & Plans

China Unveils Latest Progress on Moon Exploration Projects & Plans

The China National Space Administration (CNSA) on Wednesday, April 24, 2024, revealed the latest developments in its lunar exploration projects at an event held in Wuhan City, central China's Hubei Province, along with a preview of their plans ahead.

The unveiling of the concept video for the international lunar research base has generated great anticipation, showcasing the diverse range of functions of the base.

The project is envisioned as a comprehensive scientific experimental base capable of conducting interdisciplinary and multi-objective research activities focusing on lunar exploration and utilization. It will be capable of long-term independent operation, either on the lunar surface or in lunar orbit.

With the continuous accumulation of its deep space exploration technology and experience,China has developed research directions for deep space and international lunar scientific research stations.

"We were able to reach the moon in the past, but now our main focus is to conduct scientific experiments and exploration on its surface. We used to go to a certain point, but now we aim for extensive and in-depth exploration. Previously, government initiatives took the lead, but now there is a shift towards actively involving commercial space ventures under government guidance. Multiple countries are joining forces and collaborating to conduct exploration together," said Wu Weiren, chief designer of China's lunar exploration program.

Wu further explained that the international lunar research base will be constructed in two phases. The first one aims to establish comprehensive scientific facilities with basic functions and essential supporting elements around the lunar south pole by 2035. The second phase plans to build a well-equipped and stable facility of considerable scale around the lunar orbital station by 2045.

"The moon serves as a starting point, and an international lunar research station will provide a platform for long-term scientific research, work and habitation, paving the way for future human exploration into deeper space. It will serve as a technological, material, and intellectual reservoir, preparing us for future missions to Mars and other distant destinations in space," said Wu.

China is Building a Lunar Satellite Constellation | Dongfang Hour

China is Building a Lunar Satellite Constellation | Dongfang Hour

As China ramps up its lunar exploration program in the coming decade, space-based lunar infrastructure is going to be a key enabler. Spacecraft and ground-based vehicles will increasingly need positioning and communication services. This is why China has launched a plan to establish a lunar satellite constellation called the "Queqiao constellation". The focus on the far side and the lunar south pole also means that communications will require relay satellites.

In preparation for this lunar constellation, expected in the 2030s, China has been launching single Queqiao spacecraft: the "Queqiao" in 2018, "Queqiao-2" in March 2024, and "Queqiao-3" by the end of the decade.

In this video, we cover this quest for lunar infrastructure, a low key, but essential milestone, for the establishment of China's future lunar outpost, the International Lunar Research Station (ILRS).

Fourth Global Coral Bleaching Event Confirmed by U.S. Scientists | NOAA

Fourth Global Coral Bleaching Event Confirmed by U.S. Scientists | NOAA

The world is currently experiencing a global coral bleaching event, according to National Oceanic and Atmospheric Administration (NOAA) scientists. This is the fourth global event on record and the second in the last 10 years.  

Bleaching-level heat stress, as remotely monitored and predicted by NOAA’s Coral Reef Watch (CRW), has been—and continues to be—extensive across the Atlantic, Pacific and Indian Ocean basins. CRW's heat-stress monitoring is based on sea surface temperature data, spanning 1985 to the present, from a blend of NOAA and partner satellites.
