Summer stargazing treat as Perseid meteor shower reaches its peak
Wednesday, 04 August 2021 12:35
The Perseid meteor shower reaches its peak on the night of 11–12 August, giving skywatchers a potentially impressive summer treat. The meteors are best viewed from the northern hemisphere, and in ideal conditions with no clouds observers could see up to 50 an hour.
Meteors are the result of small particles entering the Earth's atmosphere at high speed, typically around 60 km per second.
What it takes to become Australia's first woman astronaut
Wednesday, 04 August 2021 12:31
I'm currently training to become Australia's first woman astronaut. I expect to fly my first suborbital mission sometime in 2023 as a payload specialist on a commercial mission. In other words, I'll be one of few certified crew members who can handle specialized scientific equipment aboard a suborbital spacecraft.
Once we're up there, my team and I expect to conduct research on Earth's atmosphere. It's an opportunity I consider out of this world. But it has taken a lot of effort for this dream to be realized.
My path to PoSSUM
As a female STEM and legal professional, my past jobs included working as a research scientist in mining and metals for BHP-Billiton, Rio Tinto and the Australian Nuclear Science and Technology Organisation (ANSTO)—but I always loved space.
SpaceX surges Starship work despite FAA environmental review uncertainty

Space station mishap caused orbiting lab to rotate 1 1/2 times, NASA says
Wednesday, 04 August 2021 08:13
The International Space Station spun around 1 1/2 times on its main axis last week when a new Russian segment of the orbiting platform malfunctioned, a NASA spokesman said, as new details emerged about the incident.
"Mission control got alerts on the ground at the same time astronauts got an alert that the attitude [position] of the space station was changing," Dan Huot, a NASA public a The rise of oxygen on early Earth linked to changing planetary rotation rate
Wednesday, 04 August 2021 08:13
The rise of oxygen levels early in Earth's history paved the way for the spectacular diversity of animal life. But for decades, scientists have struggled to explain the factors that controlled this gradual and stepwise process, which unfolded over nearly 2 billion years.

Iridium Communications reports that Japan's Ministry of Internal Affairs and Communications (MIC) has approved regulatory amendments necessary to allow for Japanese adoption of Iridium Certus broadband, Iridium Controller-Pilot Data Link Communications (CPDLC) and other aeronautical services for aviation and Iridium's Global Maritime Distress and Safety System service (GMDSS).
Over the pas Finding the cause of a fatal problem in rocket engine combustors
Wednesday, 04 August 2021 08:13
Rocket engines contain confined combustion systems, which are, essentially, combustion chambers. In these chambers, nonlinear interactions among turbulent fuel and oxidizer flows, sound waves, and heat produced from chemical reactions, cause an unstable phenomenon called 'combustion oscillations.'
The force of these oscillations on the body of the combustion chamber-the mechanical stress o Boeing postpones Starliner capsule launch attempt over valve issue

ULA had planned to launch an Atlas V rocket carrying the uncrewed Department of Energy to provide $100 million for high energy physics research
Wednesday, 04 August 2021 08:13
Today, the U.S. Department of Energy's (DOE's) Office of Science announced a plan to provide $100 million over the next four years for university-based research on a range of high energy physics topics through a new funding opportunity announcement (FOA). The objective of this funding is to advance knowledge of how the universe works at its most fundamental level.

Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used a completely different approach to produce metallic water and documented the phase transition at BESSY II. The study is published now in Nature.
