Magnetic and acoustic levitation to protect bioprint heart models against radiation

Posted by in categories: bioprinting, biotech/medical, health, space travel

Reducing reliance of aninmal experimentation. 🐀

According to the team, this new unparalleled technology facilitates the precise manipulation of biological materials, enabling the creation of highly sophisticated and realistic organoids that closely mimic the complexity of the corresponding human organs.

The cutting-edge magnetic and acoustic levitation will bioprint heart models to improve protection against radiation both in space and on Earth.

GravityLab wants to tackle the artificial gravity problem

Posted by in categories: biotech/medical, space travel

Living without gravity spells disaster for the human body. Even a few weeks in microgravity can lead to issues with circulation and vision; over the longer term, the complications compound even further. The heart begins to degenerate and atrophy. Bones turn thin and brittle.

But what about Martian gravity, which is around 0.38 that of Earth? Or somewhere in-between — 0.16 G on the moon, or 0.91 on Venus? How do these gravity levels affect the body, plants and other organisms, even manufacturing processes? We have astonishingly few answers to these questions.

gravityLab wants to find some. The company is developing a spinning spacecraft that will be able to generate what co-founder and CEO Grant Bonin calls “programmable gravity.” The spacecraft will be equipped with a motorized boom that can extend and retract a counterweight. By dynamically varying the length of the boom and the rotation rate, the company says it will be able to control the acceleration of gravity inside the spacecraft.

Blue Alchemist to make solar cells on the Moon using moondust

Posted by in categories: solar power, space travel, sustainability

With the aim of allowing astronauts to live off the land as much as possible when they return to the Moon, NASA has awarded Blue Origin a US$35-million Tipping Point contract to develop the company’s Blue Alchemist process to make solar cells out of lunar soil.

The biggest bottleneck to establishing a permanent human presence on the Moon and beyond is the staggering cost of sending equipment and supplies from Earth. NASA and other space agencies believe that the best way to overcome this is to use local resources as much as possible to manufacture what’s needed.

Under development since 2021, Blue Alchemist is an example of this. The basic concept is to develop a complete process that takes the lunar soil, more formally known as the regolith, at one end and spits out complete solar cells and other products at the other.

A Starship space station? NASA wants a modified SpaceX Mars rocket to orbit Earth

Posted by in categories: Elon Musk, space travel

The Starship upper stage’s impressive 29.5-foot diameter means it could fit up to 100 passengers at a time.

SpaceX’s Starship rocket program is the culmination of founder Elon Musk’s original plan of sending humans to Mars and making humans an interplanetary species.

Revolutionizing Nuclear Thermal Propulsion in Space with DRACO

Posted by in categories: chemistry, space travel

Chemical propulsion has long been the standard for spaceflight, but for humans to reach Mars, we’ll need a much more powerful and efficient propulsion. Nuclear thermal propulsion (NTP) engines offer thrust as high as conventional chemical propulsion with much higher efficiency.

Researchers discover mysterious interstellar radio signal reaching Earth: “Extraordinary”

Posted by in categories: materials, space travel

Mysterious radio wave pulses from deep in space have been hitting Earth for decades, but the scientists who recently discovered them have no concrete explanation for the origin of the signals.

For 35 years, the strange blasts of energy in varying levels of brightness have occurred like clockwork approximately every 20 minutes, sometimes lasting for five minute intervals. That’s what Curtin University astronomers from the International Centre for Radio Astronomy Research (ICRAR) concluded in research published last week in the journal Nature.

The discovery of the signal, which researchers named GPMJ1839-10, has the scientists baffled. Believed to be coming from around 15,000 light years away from Earth, the signal has been occurring at intervals and for a period of time previously thought to be impossible.

A fusion rocket designed to travel 500,000 mph is under construction

Posted by in categories: habitats, health, space travel

A British aerospace startup is working on a fusion rocket it says will slash the amount of time it takes astronauts to travel to Mars and beyond — allowing humans to explore places that are currently far out of reach.

The challenge: Long-term exposure to microgravity and cosmic radiation can cause serious health issues for astronauts. That means NASA needs to keep its future Mars missions short enough that astronauts come home healthy — less than 4 years should work.

Using our current rocket propulsion technology, though, it’s going to take seven months just to get astronauts to Mars. Factor in the amount of time to get back to Earth, and nearly a third of a Mars astronaut’s mission is just going to be dedicated to the commute.
