Chief Engineer Elon Musk founded SpaceX with the goal to enable humans to live on Mars. The aerospace company is developing its next-generation launch vehicle in South Texas at Boca Chica Beach. According to SpaceX, Starship will be the most powerful rocket in the world; It will be a 120-meter-tall, two-stage launch vehicle consisting of a spacecraft capable of carrying one hundred passengers, and a Super Heavy booster used to propel the craft out of Earth’s atmosphere.
During the Humans To Mars teleconference that took place on Tuesday, Musk said Starship’s Super Heavy “booster prototype one” will initiate construction “this week.” SpaceX Boca Chica teams are building multiple Starship prototypes at the assembly facility, where gigantic vehicle assembly buildings are taking shape to accommodate the massive stainless-steel rocket booster. – “Making a prototype of something is, I think, relatively easy,” he said, “But building the production system so that you can build ultimately hundreds or thousands of Starships, that’s the hard part.”
Israeli VTOL air taxi developer Urban Aeronautics has announced it’s partnering with HyPoint to develop a long range, hydrogen-fuel-cell-powered, emissions-free version of its remarkable CityHawk aircraft, based on the military Cormorant/AirMule design.
HyPoint’s “turbo air-cooled” fuel cell design radically expands the power and lifespan of traditional designs, making it an ideal lightweight powertrain component for aviation use. Hydrogen is becoming one of the most exciting technologies in the emerging electric aviation market, with exceptional energy density compared to lithium batteries, as well as super-quick refueling as compared to long waits on a battery charger.
The CityHawk airframe looks like no other design in the eVTOL air taxi market. It has no wings or external propeller arms, and isn’t much bigger than a large SUV. Urban Aeronautics calls it a “fancraft,” after the large fans at the front and rear of the aircraft, totally shielded thanks to tiltable vanes at both the inlet and outlet sides, which can be moved to effect yaw and horizontal movements. For such a tiny ground footprint, it offers an impressive capability to seat six people.
But the question a lot of us in Australia might have is, when there are plenty of other protein options, why should we bother eating insects?
Insects are delicious and nutritious and can be grown in shipping containers in the middle of cities and towns. Is it time Australians joined the 2 billion people around the world who eat insects daily?
MINNEAPOLIS — A new study is sounding the alarm for patients taking dozens of common prescription and over-the-counter drugs. Researchers find that taking a particular class of drug, anticholinergics, increases the risk of developing mild thinking and memory problems.
The study shows there are about 100 of these types of drugs in widespread use. These medications treat everything from colds to high blood pressure to depression.
The research, published in the journal Neurology, finds that people with genetic risk factors for Alzheimer’s disease are particularly susceptible to these issues. Overall, scientists reveal patients with no cognitive issues are 47 percent more likely to develop a mental impairment if they’re taking at least one anticholinergic drug.
Hubble Targets Tilted Galaxy
Posted in cosmology
The blue and orange stars of the faint galaxy named NGC 2188 sparkle in this image taken with the NASA/ESA Hubble Space Telescope. Although NGC 2188 appears at first glance to consist solely of a narrow band of stars, it is classified by astronomers as a barred spiral galaxy. It appears this way from our viewpoint on Earth as the center and spiral arms of the galaxy are tilted away from us, with only the very narrow outer edge of the galaxy’s disk visible to us. Astronomers liken this occurrence to turning a dinner plate in your hands so you see only its outer edge. The true shape of the galaxy was identified by studying the distribution of the stars in the inner central bulge and outer disk and by observing the stars’ colors.
NGC 2188 is estimated to be just half the size of our Milky Way, at 50,000 light-years across, and it is situated in the constellation of Columba (the Dove). Named in the late 1500s after Noah’s dove in biblical stories, the small constellation consists of many faint yet beautiful stars and astronomical objects.

The bags of cannabis were dropped by the “green drone” Telegram group, which advocates for the legalization of cannabis in Israel, with “free love” being the group’s slogan.
Before dropping the cannabis over Tel Aviv, the group published a message on Telegram, hinting at the planned operation.
“It’s time my dear brothers. Is it a bird? Is it a plane? No, it’s the green drone, handing out free cannabis from the sky… Enjoy my beloved brothers, this is your pilot brother, making sure we all get some free love,” the message read.
The FBI is conducting a probe after a pilot from American Airlines reported a man flying a jetpack above Los Angeles International Airport Sunday night.
“The FBI is aware of the reports by pilots on Sunday and is working to determine what occurred,” a spokesperson told FOX 11 Tuesday.
A second pilot from a separate airline company also reportedly spotted a man using a jetpack as the planes were approaching the airport at around 3,000 feet and 10 miles out for a landing.
This course is for students wishing to explore blockchain technology’s potential use—by entrepreneurs and incumbents—to change the world of money and finance. The course begins with a review of Bitcoin and an understanding of the commercial, technical, and public policy fundamentals of blockchain technology, distributed ledgers, and smart contracts. The class then continues on to current and potential blockchain applications in the financial sector.
