Why are scientists shooting mushrooms into space? — Shannon Odell

Posted by in category: space travel

Explore the unique characteristics that make fungi so resilient, and find out why they may be the key to future space travel.

Astronauts aboard the space station Mir made a frightening discovery: several species of Earth-derived fungi were found growing throughout the shuttle, blanketing air conditioners and corroding control panels, putting both the station’s integrity and their lives at risk. How had the fungi survived the journey to space? Shannon Odell shares why fungi may be the key to our future on other planets.

Space mission that maps forests in 3D makes an early comeback

Posted by in categories: mapping, robotics/AI, space

Call it the force’s doing, but it has been surprises galore for the GEDI mission.

In early 2023, the lidar mission that maps the Earth’s forests in 3D was to be burned up in the atmosphere to make way for another unrelated mission on the International Space Station. A last-minute decision by NASA saved its life and put it on hiatus until October 2024. Earlier this year, another surprise revealed itself: the mission that replaced GEDI was done with its work, effectively allowing GEDI to get back to work six months earlier than expected.

That’s how, in April, a robotic arm ended up moving the GEDI mission (short for Global Ecosystem Dynamics Investigation and pronounced “Jedi” like in the Star Wars films) from storage on the ISS to its original location, from where it now continues to gather crucial data on aboveground biomass on Earth.

Near-extinct Siamese crocs make comeback in Cambodia

Posted by in category: futurism

Cambodia has welcomed 60 baby Siamese crocodiles — a hatching record for the endangered species in this century, conservationists say.

They have called it a “real sign of hope”, after more than 20 years of efforts to revive the reptile’s numbers in the remote Cardamom Mountains.

The olive green freshwater reptile has a distinct bony crest at the back of its head — by some estimates, it can grow up to 3m or nearly 10ft.

World’s first dual-tower solar thermal plant boosts efficiency by 24%

Posted by in categories: solar power, sustainability

Two 650-foot-tall (200-m) towers have risen in China’s Gansu Province. Combined with an array of 30,000 mirrors arranged in concentric circles, the new facility is expected to generate over 1.8 billion kilowatt-hours of electricity every year.

While photovoltaic panels that directly convert sunlight to electricity are what most people think of when they hear the term “solar power,” there is another method of harvesting the Sun’s power that’s been steadily developing since the early 1980s. Known as solar thermal or concentrated solar power (CSP), these systems rely on mirrors known as heliostats to bounce sunlight to a central gathering point. There, the concentrated beams heat a transfer fluid that in turn heats a working fluid. This fluid then evaporates, turns a turbine, and generates electricity.

High-speed rail project linking two major U.S. cities takes step forward: ‘A historic milestone’

Posted by in category: transportation

The California High-Speed Rail Authority just received environmental approval to connect downtown Los Angeles to the Bay Area with a bullet train capable of reaching speeds of up to 200 miles per hour, KTLA5 reported.

KTLA5 called the approval “a historic milestone in a state notorious for holding up construction projects for environmental review.”

NASA, SpaceX Unveil Spaceship That Will Take International Space Station Out Of Orbit

Posted by in category: space travel

Once docked, the ISS will “drift down” to 220 km (136 miles) above the Earth’s surface over the following year.

Once in position, the vehicle will fire its 30 Draco engines for a series of burns setting up for a final re-entry burn four days later.

The deorbiting vehicle will be tasked with firing its engines to keep the station on course and powering it when comes into contact with thickening layers of the upper atmosphere during its descent.
