Researchers tapped again for NASA moon mission, set to explore mysterious domes
Monday, 06 June 2022 16:09
A team of researchers from the University of Central Florida will be exploring an unknown and mysterious region of the moon.
Two UCF planetary scientists, Kerri Donaldson Hanna and Adrienne Dove, have been asked to lead a $35 million mission which would land a spacecraft over the Gruithuisen Domes—an unexplored part of the moon that has left NASA scientists scratching their heads, according to a NASA press release.
The domes, which are found on the western part of the moon, appear to be the result of a rare form of volcanic eruption, according to NASA. What's mysterious about the domes is that such geological structures on Earth require oceans of liquid water and plate tectonics to form. Without such ingredients, NASA scientists are left baffled as to how the structures came to be.
Donaldson Hanna and Dove's work is part of NASA's plan to use more commercial companies to take payloads to the moon through its Commercial Lunar Payload Service program (CLPS), which is headquartered in the Johnson Space Center in Houston. The CLPS program is born from NASA's Artemis lunar exploration plans and efforts to get humans back on the moon.
What is the best radiation shielding for the surface of Mars?
Monday, 06 June 2022 14:34
The planet Mars is calling to us. At least, that is the impression one gets when examining all the planned and proposed missions to the red planet in the coming decade. With so many space agencies currently sending missions there to characterize its environment, atmosphere, and geological history, it seems likely that crewed missions are right around the corner. In fact, both NASA and China have made it clear that they intend to send missions to Mars by the early 2030s that will culminate in the creation of surface habitats.
To ensure astronaut health and safety, both in transit and on the surface of Mars, scientists are investigating several means of radiation protection. In a recent study, a team from the Blue Marble Space Institute of Science (BMSIS) studied how various materials could be used to fashion radiation-protective structures. This included materials brought from Earth and those that can be harvested directly from the Martian environment.

Mars is all shook up
Monday, 06 June 2022 09:30
Recently, 47 new 'marsquakes' (that is, quakes on Mars) have been detected by Professor Hrvoje Tkalcic from the Australian National University and Professor Weijia Sun from the Chinese Academy of Science. The discovery suggests Mars to be more seismically active than previously thought.
The findings also provide clues about the composition of Mars and how other rocky planets in our Solar S Subscale booster motor for future Artemis missions fires up at Marshall
Monday, 06 June 2022 09:30
Engineers successfully fired a 2-foot-diameter, subscale solid rocket booster June 1, 2022, at NASA's Marshall Space Flight Center in Huntsville, Alabama.
The test, conducted in Marshall's East Test Area, produced 92,000 pounds of thrust and was done as part of the booster obsolescence and life extension (BOLE) program, providing an upgraded booster design for the evolved configuration of China discloses tasks of Shenzhou-14 crewed space mission

The upcoming Shenzhou-14 crewed space mission will complete the construction of the Tiangong space station, with a basic three-module structure consisting of the core module Tianhe and the lab modules Wentian and Mengtian, according to the China Manned Space Agency (CMSA) on Saturday.
The mission will build the space station into a national space laboratory, said Lin Xiqiang, deputy direct Aegis Aerospace and Intuitive Machines team up for lunar science services

Six microsatellites developed by Space Flight Laboratory (SFL) were successfully launched by the SpaceX Transporter-5 rideshare mission on May 25. The three GHGSat greenhouse gas monitoring and three HawkEye 360 radio frequency (RF) geolocation microsatellites bring to 36 the total number of SFL-built satellites placed into orbit since 2020.

Scientists who study the cosmos have a favorite philosophy known as the "mediocrity principle," which, in essence, suggests that there's really nothing special about Earth, the Sun or the Milky Way galaxy compared to the rest of the universe.
Now, new research from CU Boulder adds yet another piece of evidence to the case for mediocrity: Galaxies are, on average, at rest with respect to th Time crystals "impossible" but obey quantum physics
Monday, 06 June 2022 09:30
Scientists have created the first "time-crystal" two-body system in an experiment that seems to bend the laws of physics.
It comes after the same team recently witnessed the first interaction of the new phase of matter.
Time crystals were long believed to be impossible because they are made from atoms in never-ending motion. The discovery, published in Nature Communications, shows th Seen from space, the snow-capped Alps are going green
Monday, 06 June 2022 09:30
The famous snow-capped peaks of the Alps are fading fast and being replaced by vegetation cover - a process called "greening" that is expected to accelerate climate change, a study said Thursday.
The research, published in Science, was based on 38 years of satellite imagery across the entirety of the iconic European mountain range.
