How NASA’s spacecraft will smash into an asteroid and save Earth from harm next year

image?fit=796%2C417&url=https%3A%2F%2Fcd
A NASA spacecraft the size of a golf cart has been directed to smash into an asteroid, with the intention of knocking it slightly off course. The test aims to demonstrate our technological readiness in case an actual asteroid threat is detected in the future. The Double Asteroid Redirection Test (DART) lifted off aboard a SpaceX rocket from California on November 23, and will arrive at the target asteroid system in September, next year. The mission will travel to the asteroid Didymos, a member of the Amor group of asteroids. Every 12 hours Didymos is orbited by a mini-moon, or…

Scientists gain new insight into the atmosphere of Pluto

In the middle of August 2018, the dwarf planet Pluto passed in front of the star giving astronomers an ideal opportunity to learn more about the atmospheric density of the former planet. Researchers from the Southwest Research Institute and a team of astronomers used telescopes at numerous sites in the US and Mexico to observe the atmosphere of Pluto as … Continue reading

Astronomers have captured the best images yet of Kleopatra, a 168-mile-long asteroid nicknamed the “dog-bone” on account of its unusual shape. The latest observations are offering fresh insights into the object’s shape and precarious spin and how its moons likely came into existence.

How Do We Know How Old Fossils Are?

16b9db9803b90c4dfbce8f9b59d1111f.jpg

Paleolithic hunters built mammoth traps in what is now Mexico some 14,700 years ago. An unknown sea creature left footprints in sand some 550 million years ago, making them the oldest known footprints on Earth. The mysterious Denisovan humans reached southeast Asia 160,000 years ago, as evidenced by a jawbone found on…

A giant asteroid buzzed the Earth yesterday

A gigantic asteroid that is considered potentially hazardous by NASA zipped past the Earth yesterday at a very high rate of speed. The asteroid, called 2016 AJ193, flew past the Earth at a velocity of 58,000 mph. It’s hard to imagine a speed that high; it equates to traveling about 16 miles every second. NASA estimates the asteroid is about … Continue reading

Swiss university claims it broke the record for Pi calculation

6fa8c160-ff4c-11eb-a5df-793dce95a855

Most people know the value of Pi as 3.1416, but it’s gotten longer and longer over the years as researchers try to find its most accurate calculation. A team from the University of Applied Sciences Graubünden in Switzerland now claims it has broken the world record for computing for the mathematical constant: It said it has calculated for 62.8 trillion digits of Pi. The current record holder, Timothy Mullican, calculated up to 50 trillion digits and was recognized for his work last year. 

According to the Swiss university, its team took 108 days and 9 hours to compute for the new value. That’s 3.5 times faster than Mullican’s efforts and almost twice as fast as the record Google set in 2019. A couple of years ago, Emma Haruka Iwao and her colleagues used the power of 25 Google Cloud virtual machines to calculate for 31,415,926,535,897 digits of Pi within 121 days. 

The Swiss team, as The Register explains, used a rig powered by two 32-core AMD Epyc 7542 processors with 1 TB of RAM and a program called y-Cruncher. Its setup had 38 hard drives with 16 TB of storage space each, 34 of which were used for the process while four were used to store the new value of Pi. The team didn’t use SSDs, even though their speed would’ve made the process quicker, because the large number of write cycles needed for Pi calculation would’ve resulted in high wear and tear on the SSDs, which aren’t cheap. That wouldn’t have worked, since the university wanted to demonstrate that it’s possible to carry out an extremely memory-intensive calculation with limited budget and resources. Guinness has yet to confirm the new record, but after it does, the university plans to publish the new and expanded value of Pi.

Are Lightsabers Theoretically Possible?

b9372bca9f5e298595b10b357c2f70a6.png

I’ve never been a Star Wars fan. I’ve seen only one of the movies, The Phantom Menace, and I was eight years old at the time. And yet even I, as a child, owned and played with one of those little lightsaber toys, as have millions of children before and after me (not to mention the millions of children yet-unborn, who…

NASA’s Perseverance rover fails to collect its first Mars rock sample

b8351220-f78c-11eb-bbbf-f98fd8eb2a9e

NASA’s Perseverance rover just had a rare misstep. The space agency has revealed that the robotic vehicle failed to collect Mars rock samples during its first attempt. While the percussive drill, coring bit and sample tube processing worked “as intended,” a probe indicated that the tube was empty — not exactly what scientists were expecting when everything else checked out.

Scientists are still investigating what happened and may not have an answer for a few days. Perseverance project manager Jennifer Trosper said the team suspected the rock might have reacted in an unexpected way during the coring process. The equipment is likely fine, in other words.

The Martian surface has created problems more than once. The Phoenix Lander had trouble gathering “sticky” soil in 2008, for instance, while Curiosity and InSight have also had trouble cracking into rocks and the surface itself.

This initial setback won’t necessarily jeopardize Perseverance’s mission. However, NASA will want to keep incidents like this to a minimum. The rover was sent to Mars in no small part to collect samples that would eventually return to Earth and help scientists look for signs of past life. The fewer samples NASA gets, the fewer chances it will have to explore Mars’ history.
