Scientists finally confirm how long a day is on Venus

Jak Connor | May 3, 2021 8:33 AM CDT

Venus is a neighboring planet of ours, and despite its close position to Earth, there is still quite a lot of things we don't know about it.

Scientists finally confirm how long a day is on Venus

One of those mysteries was 'how long is a day on Venus?'. Now, researchers from the University of California have managed to figure it out after 15 years of observations. The researchers used a radar to bounce radio signals off of the surface of the planet. From doing this, the researchers learned not only how long a day is on the sister planet but also the actual size of the planet's core, as well as how much it's tilted.

The researchers found that one day on Venus is 243.0226 Earth days or two-thirds of an Earth year. The reason for a day on Venus being 243 Earth days is because Venus rotates extremely slowly. Researchers suspect that Venus' thick layer of sulfuric acid clouds may be impacting the speed at which the planet is rotating. As for the core, researchers found that the planet's core is 2,200 miles across, which is similar to the size of Earth's core. For more information on this story, check out this link here.

China's rocket will crash back to Earth this week, could hit a city

Jak Connor | May 3, 2021 7:32 AM CDT

Last week, China launched its first piece of its own space station that is expected to be completed by 2022.

China's rocket will crash back to Earth this week, could hit a city

Unfortunately, the launch wasn't all sunshine and rainbows as a 21-tonne rocket that carried the space station module to space is now going to crash back down to Earth. SpaceNews has reported that the Long March 5B rocket is out of control, and is likely to crash back down to Earth in the coming days. The rocket is currently travelling at 16,000 mph, and is circulating the Earth every 90 minutes.

Another unfortunate factoid is that due to the ever-changing variables of the rocket it's almost impossible to predict where it's going to land. At the moment projections estimate that the rocket could land anywhere between New York in the northern hemisphere and Wellington, New Zealand, in the southern hemisphere. Luckily, majority of the planet is covered in water, so the chances are it will land somewhere in the ocean, and not in someones backyard.

Scientists caught a real-life giant 'kraken' on video, here's how

Giant squid caused many people to tell tales of what was known in folklore as the Kraken. Now, researchers have found the real-life "Kraken", the Architeuthis dux.

Scientists caught a real-life giant 'kraken' on video, here's how

The Architeuthis dux (A. dux) is the world's largest known squid, and while it's not as big as the folklore tales describe the Kraken to be, it's still incredibly large growing to about 46 feet, or about the length of a semi-trailer. These giant squid are hardly spotted in their natural habitat, but that all changed back in 2012 when a team of marine scientists managed to capture a young A. dux 2,000 feet below the sea in south Japan.

A new study has explored why these giant squid, despite their size, are so hard to capture in their environment. The researchers explain that part of the reason the giant squid is so hard to observe in its natural habitat is because of its massive eyes. Due to the A. dux living so far beneath the ocean's surface, the creature has developed the largest eyes in the animal kingdom, as no sunlight can penetrate to the depth of its natural habitat.

US Defense Secretary drops warning about next major war

Jak Connor | May 3, 2021 3:32 AM CDT

The United States wants to leave behind the way it has fought previous wars and move into something that is "very different".

US Defense Secretary drops warning about next major war

According to speech excerpts provided to Reuters, United States Defense Secretary Lloyd Austin says, "The way we'll fight the next major war is going to look very different from the way we fought the last ones". Speech excerpts called for harnessing technological advances, as well as implementing military operations globally as it will allow the US to "understand faster, decide faster, and act faster."

The speech excerpts didn't mention rival nations such as China or Russia, but the speech excerpts have been published right as President Joe Biden has ordered US troops to withdraw from Afghanistan. Austin also states that the last two decades have been spent "executing the last of the old wars", and understanding the mistakes that were made. It should be noted that Austin didn't make any statements regarding what the US will be doing specifically and to what country.

Flat Earth theory was debunked 2,000 years ago, explains Carl Sagan

Jak Connor | May 3, 2021 2:31 AM CDT

More than 2,000 years ago, a Greek mathematician proved that the surface of the Earth was curved and not flat.

Flat Earth theory was debunked 2,000 years ago, explains Carl Sagan

That mathematician was Eratosthenes, who was a geographer, poet, astronomer, and music theorist. So, how did a mathematician debunk the modern-day theory that the Earth is flat 2,000 years ago? As explained by Carl Sagan in the above video, Eratosthenes planted a stick in the ground in Syene, a city south of Alexandria, and another in Alexandria. The distance between the two sticks was 800 kilometers.

Now, if both of the sticks that were planted casted an identical shadow at the same time of day, it would suggest that the surface of Earth is flat. However, Eratosthenes found that the shadow casted by one of the sticks wasn't identical to the other, in fact, the difference between the shadow casted in Alexandria, and the one in Syene was 7 degrees.

Check out the Royal Marines board a ship with jetpacks like Iron Man

Anthony Garreffa | May 2, 2021 10:31 PM CDT

I don't know about you but I would do anything to fly around in one of these Gravity Jet Suits, just like the Royal Marines did during a successful training exercise using the Iron Man-like jet suits. Check them out, taking off, flying up and next to and then landing on the ship.

Check out the Royal Marines board a ship with jetpacks like Iron Man

The Royal Marines are using Gravity Industries' own Gravity Jet Suit here for their operations, with 1000bhp of Jet Engine power to fly around with. The marines look so awesome easily flying off from their boat onto the ship, flying up to it and gracefully landing onto it -- reminding me of the graceful way Christopher Reeves' Superman used to land in the original Superman movies.

Former Oil Trader & Royal Marines Reservist, Richard Browning, founded Gravity Industries in March 2017 to introduce what will be a part of the future of combat -- taking "human flight into an entirely new era" explains the company on their YouTube video.

NASA + SpaceX $2.9B moon lander deal paused, competitors file protests

Anthony Garreffa | May 1, 2021 10:06 PM CDT

Damn... and just like that NASA and SpaceX have had their $2.9 billion Starship-based lunar landing system deal torn up and thrown into space -- I guess where no one can hear (everyone who wants to see this happen) scream.

NASA + SpaceX $2.9B moon lander deal paused, competitors file protests

The reason? Blue Origins Federation and Dynetics have submitted protests with the US Government Accountability Office, stopping the NASA and SpaceX deal far, far before liftoff. The space industry expected the historic $2.9 billion contract would go to two companies, but it went to one -- SpaceX -- and now its competitors are pissed.

Dynetics filed a protest with the US Government Accountability Office, arguing that NASA chose "the most anti-competitive and high risk option available" when it tasked SpaceX with using its Starship to build a Human Landing System for its mission to the moon.

Tesla Powerwall+ teased: upgraded battery for improved off-grid living

Anthony Garreffa | May 1, 2021 9:30 PM CDT

It looks like Tesla has silently launched its upgraded Powerwall+ system, not long after Elon Musk updated the world through Twitter on the power upgrades to Powerwall.

Tesla Powerwall+ teased: upgraded battery for improved off-grid living

The new Tesla Powerwall+ system has a much upgraded max power output, with 9.6kW max power output up from 7kW on the regular Powerwall. The new Powerwall+ system also has a new inverter with an integrated breaker that sits above the Powerwall+ which will provide Powerwall+ owners with a new unique look over the regular Powerwall installation.

Tesla explains its new Powerwall+ battery pack: "Powerwall+ is an integrated solar battery system to store energy from solar production. Its integrated design and streamlined installation allow for a simple connection to any home, and improved surge power capability brings whole home backup in a smaller package. System smart controls enable owners to customize system behavior to suit their renewable energy needs".

Intel Atom + Phison SSD inside of Mars $2.7 billion Perseverance rover

Anthony Garreffa | Apr 30, 2021 6:28 PM CDT

Intel Inside has been a marketing term for what feels like forever, but now Intel is Inside of NASA's Perseverance rover that is rolling around on Mars -- not only is Intel inside, but so is SSD controller giant Phison.

Intel Atom + Phison SSD inside of Mars $2.7 billion Perseverance rover

Inside of the Perseverance rover is a credit-card-sized computing module that stores, and sends the photos we've been seeing from the Red Planet back to our Pale Blue Dot. The module itself is running Linux, and is powered by an Intel Atom (BayTrail) processor -- the module was made by Israel-based CompuLab in the form of the COMEX-IE38.

There are 2 x COMEX-IE38 modules inside of the NASA Perseverance rover, an off-the-shelf product that you could buy from CompuLab for around $150. There are 23 cameras on the Perseverance rover, with the data from each individual camera being fed in raw format to the DSU (data storage units) through an Ethernet link, compressed by the COMEX-IE38 module, and then stored on a 480GB SSD (thanks to Phison and its PSS4A111-8G) and then blasted back to NASA engineers back on Earth.

Humans may kill ourselves off much sooner than we think, says expert

Jak Connor | Apr 30, 2021 7:34 AM CDT

At some point, everything will come to an end, and Earth won't exist anymore, but where is that ending, and how will it be caused?

Humans may kill ourselves off much sooner than we think, says expert

A new article published in the journal Frontiers in Conservation Science by Corey Bradshaw, a scientist working in the ecology field at Flinders University and has published over 260 peer-reviewed scientific articles, has said that humanity is causing a rapid loss of biodiversity.

Through this human-induced rapid loss of biodiversity, Bradshaw says that Earth is losing its ability to support complex life. "But the mainstream is having difficulty grasping the magnitude of this loss, despite the steady erosion of the fabric of human civilization", said Bradshaw. Additionally, the article mentions that the world's economic and political systems are currently focusing on short-term solutions to problems that present themselves, which causes long-term problems such as climate change, biodiversity loss, and ecological destruction to go unnoticed.
