“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.

In a year filled with sweet new observations in astronomy and tantalizing breakthroughs in condensed matter physics, the brand-new space telescope takes the cake.

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.

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.

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.

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.

The Chandra image sets a timestamp on when young stars stop bullying their baby worlds.

The mission has concluded that the solar-powered lander has run out of energy after more than four years on the Red Planet.

Their first EV could possibly roll out with an integrated PlayStation 5.

Japanese industrial giants Sony and Honda formally joined forces earlier this year to take on the might of Tesla in the electric vehicle (EV) space. The collaborative effort will first be unveiled at the CES 2023, scheduled to be held in Las Vegas in a fortnight from now, The Verge.
