The price of bitcoin plunged about 10% hours after it was revealed that Elon Musk’s SpaceX sold the cryptocurrency.
The Wall Street Journal reported on Thursday that SpaceX, which first purchased bitcoin in 2021, wrote down the value of its bitcoin holdings by a total of $373 million in 2021 and 2022 and has sold the crypto.
The write-down coincides with a steep drop in bitcoin’s price, which crashed in late 2021, setting off a “crypto winter” that extended through most of 2022.
Elon Musk, the richest man in the world, revealed that one of the toughest choices he’s had to make in his life was when he had “$30 million dollars left.”
Musk, CEO of Tesla Inc. and SpaceX, revealed that choosing which company to invest his last $30 million in was tough.
In a conversation with screenwriter, producer and director Jonathan Nolan during a SXSW interview titled “Elon Musk Answers Your Questions!”, Musk shared his insights on topics ranging from artificial intelligence (AI) to Mars and business. He delved into his early entrepreneurial years, which ultimately led to the creation of his groundbreaking companies, including how he made $180 million from the sale of PayPal.
A functioning warp drive would allow humans to reach the far ends of the cosmos in the blink of an eye.
😗😁 2021
After appearing for decades in science fiction, then moving into an actual theory, a new patent for an updated warp drive was published last year to no fanfare. Like many other false starts in cutting-edge research, the patent may represent the next step in the expanding theory, or it could mean the practical, real-world design of a functioning warp drive is on the horizon.
Background: How to Bend Space-Time with A Warp Drive
After first publishing his groundbreaking 1994 warp drive concept in the journal Classical and Quantum Gravity, Mexican Mathematician and Physicist Miguel Alcubierre received significant positive and negative feedback. Most applauded his solution, which did indeed appear to create a working theory on how a warp drive might allow faster than light travel without violating the laws of physics. In contrast, others zeroed in on the incredible amount of energy needed to propel his theoretical spacecraft.

If you’ve been following the news recently, you know everyone is talking about how artificial intelligence (AI) is going to change everything.
Take ChatGPT, for example.
Before ChatGPT, almost no one understood what AI was and what it could do.
For most folks, AI was either an abstract concept that wouldn’t become reality or a futuristic idea like space travel.
A new project is using cutting-edge levitation techniques to make bioprinting heart models and other complex tissues a reality.
Dubbed PULSE, the project combines the recently developed techniques of acoustic levitation and magnetic levitation to manipulate individual components without actually touching them. It’s a process that the researchers involved hope will one day facilitate the bioprinting of organs and other human tissues in much greater detail and complexity than what is achievable with current techniques.
If perfected, the researchers also hope this type of bioprinting could even help on long-term space missions as more accurate organ models can create more accurate defenses against radiation and other stresses of space travel.
Russia successfully launched its inaugural moon-landing spacecraft on Friday in 47 years. The mission aims to achieve the distinction of being the first country to achieve a gentle landing on the lunar south pole, an area thought to contain valuable reservoirs of water ice.
As per a report by Reuters, Russia’s recent lunar mission, it’s inaugural one since 1976, is in a competitive race with India, which sent its Chandrayaan-3 lunar lander to space last month.
Moreover, it’s part of a larger competition involving the United States and China, both of whom have well-developed lunar exploration initiatives that focus on the southern region of the Moon.
The private space firm, Interstellar Technologies, aims for an orbital launch by 2025.
Interstellar Technologies, a Japanese startup that has successfully launched three suborbital rockets, is now gearing up for its first orbital mission. The company plans to conduct a static fire test of its Zero rocket later this year, which will be a crucial step towards launching it into orbit by 2025.

Biomethane as rocket-fuel.
Over the last several months, we’ve been enjoying a front-row seat as [Jay Bowles] of Plasma Channel has been developing and perfecting his design for a high voltage multi-stage ionic thruster. With each installment, the unit has become smaller, lighter, and more powerful. Which is important, as the ultimate goal is to power an RC aircraft with them.
There’s still plenty of work to be done before [Jay] will be able to take his creation skyward, but he’s making all the right moves. As a step towards his goal, he recently teamed up with [RcTestFlight] to attach a pair of his thrusters — which have again been further tweaked and refined since we last saw them — to a custom catamaran hull. The result is a futuristic craft that skims across the water with no moving parts and no noise…if you don’t count the occasional stray arc from the 40,000 volts screaming through its experimental thrusters, anyway.
We were particularly impressed to see the boat doesn’t use rudders, and instead relies on differential thrust between the two ion engines to turn. It was the more difficult approach to be sure, but as [Jay] explained it to us, the goal from the very start was to completely eliminate any moving components from the powertrain.
