ISS: 20 years looking over Earth

Posted by in categories: engineering, habitats, space

To mark the 20th anniversary of continuous habitation of the International Space Station, ESA commissioned two graphic artists to illustrate the Station from two perspectives. We spoke to the artists and asked them how they approached this challenge.

The International Space Station celebrates a huge milestone on 2 November 2020. For two decades, it has continuously hosted humans in space. Eighteen ESA astronauts have flown to the Station. Altogether, more than 240 crew members and visitors from 19 countries have visited the station and made it their temporary home.

A collaboration between five space agencies, the station has become a symbol of peaceful international cooperation. It represents the best of our space engineering capabilities as well as humankind’s pursuit of scientific knowledge and exploration.

It is time to return to the Moon, open Free Space and go to Mars

Posted by in categories: government, military, space

This revolution has already started, with wealthy citizens building their own space programs and entrepreneurs building spacecraft on relatively tiny budgets.


This time it must be about people, not governments. Rather than a centrally controlled quasi-military government race to space by two superpowers, we must enable the people themselves to go where they want to go, to do there what they want. If governments decide to return to the Moon — as seems to be the case — it must be to build villages, not bases, and to do it as rapidly as possible, as it needs to be an immediate challenge, not a distant dream. And if some want to go to Mars or mine asteroids, they need to be seen as part of a new frontier community. Thus, with both public and private players doing what they do best where they want to do it, we can make it happen far faster than many might believe.

Photographer Catches the ISS Crossing the Sun and Moon

Posted by in category: space

Photographer Andrew McCarthy is known for shooting incredible astrophotography images from his backyard in Sacramento, California. He recently added two more jaw-dropping images to his portfolio: ultra-clear views of the International Space Station (ISS) crossing the Sun and Moon.

Given that the ISS whizzes across the Sun and Moon in less than a second from the perspective of someone on Earth, capturing a clear view of the transit is not an easy thing to do.

McCarthy first managed to capture the ISS transiting the Sun on Tuesday, October 6th.

How to live in space: what we’ve learned from 20 years of the International Space Station

Posted by in categories: futurism, space

Twenty straight years of life in space makes the ISS the ideal “natural laboratory” to understand how societies function beyond Earth.

The ISS is a collaboration between 25 space agencies and organisations. It has hosted 241 crew and a few tourists from 19 countries. This is 43% of all the people who have ever travelled in space.

Asteroid Apophis is speeding up from sunlight as scientists recalculate odds of 2068 impact

Zap it o.o


Astronomers say they’ll have to keep an eye on the near-Earth asteroid Apophis to see how much of a danger the space rock poses to our planet during a close pass in 2068.

Applying particle physics methods to quantum computing

Posted by in categories: computing, information science, particle physics, quantum physics, space

Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has successfully adapted and applied a common error-reduction technique to the field of quantum computing.

In the world of subatomic particles and giant particle detectors, and distant galaxies and giant telescopes, scientists have learned to live, and to work, with uncertainty. They are often trying to tease out ultra-rare particle interactions from a massive tangle of other particle interactions and background “noise” that can complicate their hunt, or trying to filter out the effects of atmospheric distortions and interstellar dust to improve the resolution of astronomical imaging.

Also, inherent problems with detectors, such as with their ability to record all particle interactions or to exactly measure particles’ energies, can result in data getting misread by the electronics they are connected to, so scientists need to design complex filters, in the form of computer algorithms, to reduce the margin of error and return the most accurate results.

Scientists induce “suspended animation” state in mice and rats

Posted by in categories: food, space

Some animals, like mice and birds, are able to bring their body temperature and metabolism way down to conserve energy, going into a sleep-like state called torpor. Now researchers have identified the brain cells that trigger this state, showing they can activate it on demand. The team was even able to do it in rats, which don’t normally do it at all, suggesting that such a “suspended animation” state might eventually be possible in humans.

Torpor seems to have evolved as a survival strategy during times of food scarcity, allowing animals to snooze through cold nights or even entire winters without wasting too much energy keeping their body temperature up. That of course allows them to survive until things warm up again, and food becomes more plentiful.

Scientists have toyed with the idea of inducing this kind of hibernation state in humans to reduce the resources and room required for long treks into space. Now researchers at Harvard and the University of Tsukuba in Japan may have made progress towards doing just that.

Planet that rains rocks and has winds faster than the speed of sound discovered by scientists

Posted by in category: space

Scientists have found a planet where it rains rocks, the winds whip faster than the speed of sound and there is an ocean of magma more than 100km deep.

Researchers have found extreme “lava planets” before. They are worlds so close to their host star that the surface is made of oceans of molten lava.

But the newly-analysed planet known as K2-141b is unusual even among those extreme worlds. Its surface, ocean and atmosphere are all made up of rocks, which fall like rain and melt into its huge seas.
