V-Space (official site) is a startup that built Korea’s first UAM (Urban Air Transportation) destined to transport people or payloads of up to 120 Kg with their eVTOL all-electric vehicle. As its name indicates, it is a Vertical Take Off and Landing vehicle using a quad-copter design. It has a seat for one person and looks like a drone-like small helicopter.

EVTOL can fly over a 40-mile distance at a maximum speed of 60 Mph, a little bit below most U.S highway’s speed limits. Of course, the main advantage here is the lack of traffic jams, especially in an emergency.

However, the company has a hot new design called V Speeder-X, which looks a lot more modern and aerodynamic. The payload capacity is 230 Kg, but the speed has increased to 50 Mph as one of the use cases is to use the drone as an ambulance. Note that the flight time is relatively short, with about ~20 minutes.

Kepler asserts that its general-purpose Forerunner series showcases advanced capabilities in body movements, precise hand control, and sophisticated visual perception. This positions it as a formidable competitor to Tesla’s Optimus in the realm of humanoid robotics.

The firm claims that its humanoid robot aims to enhance “productivity with cutting-edge technology, hastening the arrival of a ‘three-day work week.’ The shift will enable humans to dedicate more time to meaningful endeavors, such as space exploration,” said Debo Hu, co-founder of the firm, in a statement.

Reminds me of how the space shuttle moved in orbit. Great idea though hopefully they’ll pass it on to us civilians too. That could be very useful. Though the military sometimes passes their tech to us like the CIA is responsible for some medical science amazingly. Yes I was surprised.

DARPA has selected Aurora Flight Sciences to build a full-scale X-plane to demonstrate the viability of using active flow control (AFC) actuators for primary flight control. The award is Phase 3 of the Control of Revolutionary Aircraft with Novel Effectors (CRANE) program.

The X-65 flight is controlled by using jets of air from a pressurized source to shape the flow of air over the aircraft surface, with AFC effectors on several surfaces to control the plane’s roll, pitch, and yaw. Eliminating external moving parts is expected to reduce weight and complexity and to improve performance.

The X-65 will be built with two sets of control actuators – traditional flaps and rudders as well as AFC effectors embedded across all the lifting surfaces. This will both minimize risk and maximize the program’s insight into control effectiveness. The plane’s performance with traditional control surfaces will serve as a baseline; successive tests will selectively lock down moving surfaces, using AFC effectors instead.

A long-awaited space mission in the coming year could herald the start of a new era where so many science fiction dreams finally begin to cement themselves as science fact. But first we must pass a critical test of our own making that pits our technological expansion into orbit against the sun itself.

It’s not that difficult to predict what science stories we’ll be talking about over the next year: artificial intelligence, climate change and advances in biotechnology will remain front of mind. But there’s a pair of happenings just beyond our planet that I’ll be watching closely, because they amount to tests of a sort that could determine the trajectory of our species.

The first story you’ve probably already heard about. NASA aims to launch its Artemis II mission by the end of the year, carrying humans on a journey around the moon and back. This marks the first time anyone has traveled farther than low-earth orbit in more than 50 years.

ESA’s Euclid mission is on a quest to unveil the nature of two elusive ‘dark’ entities. As the renowned theoretical physicist Stephen Hawking remarked in 2013, “The missing link in cosmology is the nature of dark matter and dark energy”

During the last 70 years, scientists have made enormous progress in understanding the very initial phases of the Universe and its evolution to the present day. Thanks to advances in observations and theoretical modelling, a clear picture has emerged of how stars form, and how galaxies grow and interact with each other, coming together to form groups and clusters.

Yet, fundamental mysteries remain. 95% of the Universe appears to be made up of unknown ‘dark’ matter and energy. Dark matter and energy affect the motion and distribution of visible sources but do not emit, reflect or absorb any light. And scientists do not know what these dark entities actually are.

To address this question, Euclid will create a great map of the large-scale structure of the Universe across space and time by observing with unprecedented accuracy billions of galaxies out to 10 billion light-years. This is not easy, and making sure that Euclid is up to the task has required the expertise and dedication of many people over several years of work.
