Will we ever go back to explore the ice giants? Yes, if we keep the missions simple and affordable
It's been over 35 years since a spacecraft visited Uranus and Neptune. That was Voyager 2, and it only did flybys. Will we ever go back? There are discoveries waiting to be made on these fascinating ice giants and their moons.
How karst caves can be used as a terrestrial simulation platform to test and design human bases in lunar lava tubes
If human beings want to survive on the other planets for a long time, they must first find or set up a safe, stable, and long-term shelter. Lunar lava tubes are geological structures on the moon discovered in recent years. They take the form of hollow pipe-shaped caves formed on the surface of the planet by volcanic activity.
Because a lunar lava tube has a hard basalt roof, its internal environmental factors such as temperature changes, radiation doses, and the probability of being hit by meteorites are relatively limited. As such, it offers in theory an ideal human lunar habitat. Until now, more than 300 potential cave entrances have been identified on the moon. The "skylights" they display are the result of a kind of pit caused by the active lava tube collapsing.
In a new article published in Space: Science & Technology, the research team led by Gengxin Xie and Linli Guo has discussed the feasibility of using lunar lava tubes for human habitation, proposed the idea of using the Earth's karst caves to simulate extraterrestrial lava tubes, selected caves in Chongqing as the simulation site, and demonstrated the feasibility in terms of both structural and environmental aspects.
ESA plasma sampler headed to the Moon and ISS
An innovative ESA-backed instrument to sample the space weather environment in-situ is set to join the International Space Station. Norway’s multi-Needle Langmuir Probe, m-NLP, due to be fitted to the European-made Bartolomeo platform on the ISS, a ‘front porch’ open to space, will map the ionospheric plasma surrounding the Station in unprecedented high resolution, performing almost 10 000 measurements per second continuously along its orbit.
Launches secured for five Sentinel satellites
A contract signed today between ESA and Arianespace has ensured rides into orbit for five Copernicus Sentinels: Sentinel-1D, Sentinel-2C, Sentinel-3C, and the Copernicus Anthropogenic Carbon Dioxide-A and -B satellites. All the satellites will be launched on Vega-C rockets from Europe’s Spaceport in French Guiana and are scheduled to take place between 2024 and 2026.
MTG-I1 never to be seen again
As preparations to launch Europe’s first Meteosat Third Generation Imager satellite continue, the team at Europe’s Spaceport in Kourou, French Guiana, has bid farewell to their precious satellite as it was sealed from view within the Ariane 5 rocket’s fairing. This all-new weather satellite is set to take to the skies on 13 December.
Kilometer-scale modeling better reflects the relationship between land and precipitation
The technique referred to as "dynamical downscaling", which involves the use of regional climate models to dynamically infer the effects of large-scale climate processes at local scales, has proved to be an effective way to simulate precipitation at high resolution. Moreover, with advancements in supercomputing capabilities, dynamical downscaling is now progressing to the kilometer scale.
China's two meteorological satellites put into operation
Two meteorological satellites, along with their ground application systems, have officially started operation, said the China Meteorological Administration on Thursday. The trial operation of the two satellites, Fengyun-3E (FY-3E) and Fengyun-4B (FY-4B), began in June this year. They will provide observation data and application services to global users. The FY-3E, launched on July 5
NASA Researcher's AI 'Eye' could help robotic data-gathering
When it comes to making real-time decisions about unfamiliar data - say, choosing a path to hike up a mountain you've never scaled before - existing artificial intelligence and machine learning tech doesn't come close to measuring up to human skill. That's why NASA scientist John Moisan is developing an AI "eye." Moisan, an oceanographer at NASA's Wallops Flight Facility near Chincoteague,
Webb telescope promises new age of the stars
The James Webb Space Telescope lit up 2022 with dazzling images of the early universe after the Big Bang, heralding a new era of astronomy and untold revelations about the cosmos in years to come. The most powerful observatory sent into space succeeds the Hubble telescope, which is still operating, and began transmitting its first cosmic images in July. "It essentially behaves better th
Measuring times in billionths of a billionth of a second
How fast do electrons inside a molecule move? Well, it is so fast that it takes them just few attoseconds (1 as = 10-18 s or one billionth of billionth of a second) to jump from one atom to another. Blink and you missed it - millions of billions of times. So measuring such ultrafast processes is a daunting task. Scientists at the Australian Attosecond Science Facility and the Centre for Qu
