Study reveals more hostile conditions on Earth as life evolved?
Write a comment
During long portions of the past 2.4 billion years, the Earth may have been more ?inhospitable?to life than scientists previously thought, according to?new?computer simulations.
Using a state-of-the-art climate model, researchers now believe the level of ultraviolet (UV) radiation reaching the Earth's surface could have been underestimated, with UV levels being up to ten times higher. AFRL detects moonlet around asteroid with smallest telescope yet
Write a comment
On November 29, 2021, an Air Force Research Laboratory (AFRL) Starfire Optical Range (SOR)* telescope on Kirtland Air Force Base near Albuquerque, New Mexico, recorded an image of asteroid (22) Kalliope, and its natural satellite Linus. A confirming image was taken four nights later. What is unique about these observations is the small size of the telescope used, only 1.5 meters in diameter. Russian company develops method for effective transfer of solar energy to Earth

Despite being one of the easiest and most accessible methods of gathering renewable energy, solar panels are unable to perform well in many spots of the world and in non-ideal weather conditions. In space, however, the effectiveness of solar panels increases significantly, prompting their wide use to power satellites and other spacecraft.
Russian Space Systems, a subsidiary of the Russian Advertising plays key role in satellite TV success, study shows

The pay television market in the United States was dominated by a handful of cable operators until the early 1990s with the entry of satellite TV, which has grown consistently ever since.
A new study from the University of Notre Dame documents the role of advertising to help explain satellite operators' continued success.

The previously elusive methanediol molecule of importance to the organic, atmospheric science and astrochemistry communities has been synthetically produced for the first time by University of Hawai?i at Manoa researchers. Their discovery and methods were published in Proceedings of the National Academy of Sciences on December 30.
Methanediol is also known as formaldehyde monohydrate or me ASU instrument captures breathtaking 'first light' images

ASU scientists and engineers building the Europa Thermal Emission Imaging System (E-THEMIS) for NASA's Europa Clipper passed a major hurdle recently by capturing the first successful test images from this complex infrared camera, known as "first light" images.
Europa Clipper, a NASA mission to investigate Jupiter's moon Europa, is planned to launch in October 2024 and arrive at Jupiter in Gilmour Space fires up for 2022 with Australia's largest rocket engine test

Rocket engineers at Gilmour Space Technologies have greeted the new year with a successful 110-kilonewton test fire of the most powerful rocket engine ever developed in Australia.
The 75-second test was a major milestone for Gilmour Space, which is developing Australian Made rockets that will, over the next five years, be capable of launching 300- to 4,000-kilogram satellites and payloads Cheops reveals a rugby ball-shaped exoplanet
Write a comment
ESA’s exoplanet mission Cheops has revealed that an exoplanet orbiting its host star within a day has a deformed shape more like that of a rugby ball than a sphere. This is the first time that the deformation of an exoplanet has been detected, offering new insights into the internal structure of these star-hugging planets.
Chang'E-5 lander makes first onsite detection of water on moon
Write a comment
A joint research team led by Profs. Lin Yangting and Lin Honglei from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) observed water signals in reflectance spectral data from the lunar surface acquired by the Chang'E-5 lander, providing the first evidence of in-situ detection of water on the Moon.
The study was published in Science Advances on Jan. 7.
Researchers from the National Space Science Center of CAS, the University of Hawaiʻi at Mānoa, the Shanghai Institute of Technical Physics of CAS and Nanjing University were also involved in the study.
Many orbital observations and sample measurements completed over the past decade have presented evidence for the presence of water (as hydroxyl and/or H2O) on the moon. However, no in-situ measurements have ever been conducted on the lunar surface.
The Chang'E-5 spacecraft landed on one of the youngest mare basalts, located at a mid-high latitude on the Moon, and returned 1,731 g of samples.
What happens when someone dies in space? Space tourism brings new legal and moral issues
Write a comment
Commercial spaceflight companies such as Virgin Galactic and Blue Origin are now offering exclusive opportunities for celebrities and civilians to travel to space.
Traditionally, astronauts have been subject to rigorous training and medical scrutiny before going to space, and the risk of death from natural causes was considered remote.
But in this new era of space tourism, it appears medical screening may not be carried out, and only minimal pre-flight training provided.
With a wide variety of people now going to space, and the prospect in the coming years of humans establishing bases on the Moon and beyond, it raises an important question: what happens if someone dies in space?
Under international space law, individual countries are responsible for authorizing and supervising all national space activity, whether governmental or private. In the United States, commercial tourist spaceflights require a license for launch to be issued by the Federal Aviation Administration.
Should someone die on a commercial tourist mission, there would need to be a determination as to the cause of death.
