Ultra-light electric motor to feed Australia’s first home-grown rocket

Posted by in categories: energy, space

Equipmake says it’s got the lightest and most power-dense electric motor on the market, and if there’s one place where weight is critical, it’s on a launch pad. The company has developed an ultra-lightweight motor for Australia’s first rocket launch.

Queensland-based Gilmour Space Technologies is on the home stretch making preparations for the launch of its three-stage Eris orbital launch vehicle next April. It’ll be the first orbital launch attempt of an Australian designed and built rocket, and the company hopes it’ll represent the beginning of a new space launch industry Down Under.

Ancient Mars did not have atmospheric oxygen, claims new research

Posted by in category: space

That does not mean the planet did not have life.

A new experimental study conducted by Washington University in St. Louis is defeating any hope that scientists have had that atmospheric oxygen once existed on the Red Planet, according to a press release by the institution published on Thursday.

Instead, the scientists have found that under Mars-like conditions, manganese oxides can be readily formed without any presence of atmospheric oxygen.

NASA’s Perseverance rover drops first sample on Mars, to return it to Earth one day

Posted by in category: space

“Seeing our first sample on the ground is a great capstone to our prime mission period, which ends on Jan. 6.”

NASA’S Perseverance Mars rover has dropped its first rock sample on the Red Planet’s surface. A titanium tube containing a rock sample on December 21 that was deposited on the surface of Mars is likely to be the first sample that could return to Earth. The event marks a “historic” step in the Mars Sample Return campaign.

A Physicist Came Up With Math That Shows ‘Paradox-Free’ Time Travel Is Plausible

Posted by in categories: mathematics, physics, space, time travel

No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

It’s a monumental head-scratcher known as the ‘grandfather paradox’, but a few years ago physics student Germain Tobar, from the University of Queensland in Australia, worked out how to “square the numbers” to make time travel viable without the paradoxes.

Astronomers Have Discovered The ‘Poor Old Heart’ of The Milky Way

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

A smattering of stars scattered throughout the center of the Milky Way is the remnants of the ancient galactic core, when our galaxy was still new.

Using measurements from the most accurate three-dimensional map of the galaxy ever compiled, as well as a neural network to probe the chemical compositions of over 2 million stars, a team of astronomers have identified 18,000 stars from our galaxy’s infancy, when it was just a compact collection of proto-galaxies coming together to dream of bigger things.

Hints of this stellar population have been identified in previous studies.

Strawberries in Water Bottles, Palak in PVC Pipes: 70-YO Grows all Veggies on Terrace

Posted by in categories: business, food, solar power, space, sustainability

For 70-year-old Lizy John from Bengaluru, Karnataka, nurturing a lush vegetable and fruit garden on her terrace has been highly rewarding and satisfying. Without a second thought, she credits her passion for farming to be the sole reason for staying healthy and energetic even at this age.

After running a snacks business for over 25 years, she decided to retire and focus on expanding her farming venture. Though there wasn’t enough space, she says that it wasn’t a challenge at all.

“Though we have a 1,200 sqft terrace, I grow my veggies in less than 1,000 sqft, as the solar panels and water tanks consume the rest of the space. But it was more than enough for me. I admit that I am happier and at peace ever since I started growing my own food at home,” Lizy tells The Better India.

How astronauts celebrate Christmas in space

Posted by in categories: food, space

Astronauts have marked the tradition of celebrating holidays in space since the days of the Apollo mission, when the Apollo 8 crew famously shared their Christmas Eve message in a live television broadcast in 1968 by taking turns reading from the Book of Genesis in the Bible.

The first Thanksgiving in space was celebrated on November 22, 1973, when Skylab 4 astronauts Gerald P. Carr, Edward G. Gibson and William R. Pogue each ate two meals at dinnertime, although nothing special was on the menu for the occasion. The three worked on and supported a spacewalk lasting six hours and 33 minutes earlier in the day and missed lunch.
