Temperature of solar flares helps understand nature of solar plasma
Tuesday, 16 May 2023 23:59
The Sun's rotation produces changes in its magnetic field, which flips completely every 11 years or so, triggering a phase of intense activity. Solar flares - huge eruptions from the surface of the Sun lasting minutes or hours - emit intense bursts of particles and high levels of electromagnetic radiation. The release of energy during solar flares heats the chromosphere, causing almost full ioni NASA completes heart of Roman Space Telescope's primary instrument
Tuesday, 16 May 2023 23:59
The heart of NASA's Nancy Grace Roman Space Telescope was recently delivered to Ball Aerospace in Boulder, Colorado, for integration into the WFI (Wide Field Instrument). Called the FPS (Focal Plane System), it serves as the core of Roman's camera. When the mission launches by May 2027, astronomers will use this system to gather exquisite images to help unravel the secrets of dark energy and dar BlackGEM telescopes begin hunt for gravitational-wave sources at La Silla

Let's take a walk down memory lane and take a look at the birth of satellites, why they are so critical to life on Earth today and what things would look like in a world without such connectivity enablers.
Even those who weren't born at the time, have all heard of Sputnik, the first satellite launched in October 1957. A small sphere of steel sent into space by the USSR during the cold war, 
NASA's Lunar Flashlight to fly by Earth
Tuesday, 16 May 2023 19:44
NASA's Lunar Flashlight mission to the moon has ended, but the briefcase-size spacecraft will soon fly past Earth before heading into deep space. On Tuesday, May 16, at 9:44 p.m. PDT (Wednesday, May 17, at 12:44 a.m. EDT), the CubeSat will pass about 40,000 miles (65,000 kilometers) from our planet's surface.
NASA's Eyes on the Solar System 3D visualization tool will track the tiny spacecraft in real time, giving users a front-row seat to the flyby.

Just 1 in 5 employees in the space industry are women—this lack of diversity is holding us back, say researchers
Tuesday, 16 May 2023 16:56
This week, the Australian Space Summit is celebrating some of our nation's strengths and achievements in the space sector. But it's taking place under the shadow of significant cuts to space technology investment announced in last week's federal budget.
Space technologies play a critical role in responding to many national priorities, such as climate and disaster resilience, connecting regional Australians, contributing to regional security and driving economic growth. Yet, the sector suffers from a branding issue—most people think of rockets and astronauts, rather than the satellites we depend on globally.
This leads to a misunderstanding in government of the importance of space technologies to the issues we are seeking to solve. It also makes it harder to recruit talented people to the field.
So, how do we find enough people with the skills necessary to grow this critical technology sector?
Why diversity and inclusivity matter
The answer is placing a new priority on talent recruitment and expanding diversity and inclusivity in the space sector.
The space sector needs workers from all different backgrounds and disciplines, but is struggling to attract a diverse talent pool.
Enter outer space at your own risk?
Tuesday, 16 May 2023 13:42
If you pay a company like SpaceX, Blue Origin, Virgin Galactic, or Boeing to go into space, perhaps even perform your own spacewalk, should those companies be bound by safety regulations issued by the FAA? Currently, the answer is “no,” thanks to a law that bans federal regulation of commercial space enterprises.
Space test shows magnolia may be best for wooden artificial satellite LignoSat
Tuesday, 16 May 2023 13:09
An international project led by Kyoto University tested and confirmed the high durability of space wood at the International Space Station—the ISS. The experiment results showed minimal deterioration and good stability of the samples selected for the wooden artificial satellite LignoSat.
The research group conducted a preliminary inspection involving strength tests and elemental and crystal structural analyses of the wood samples, retrieved from space by Astronaut Koichi Wakata and returned to Earth from the ISS on SpaceX CRS-26—a Commercial Resupply Service mission.
Despite the extreme environment of outer space involving significant temperature changes and exposure to intense cosmic rays and dangerous solar particles for ten months, tests confirmed no decomposition or deformations, such as cracking, warping, peeling, or surface damage.
Three wood specimens were tested and showed no deformation after space exposure. The experiment results also confirmed no mass change in each wood specimen before and after space exposure.
