Inside NASA’s Cold Atom Lab, scientists form bubbles from ultracold gas, shown in pink in this illustration. Lasers, also depicted, are used to cool the atoms, while an atom chip, illustrated in gray, generates magnetic fields to manipulate their shape, in combination with radio waves.

Produced inside NASA’s Cold Atom Lab, the bubbles provide new opportunities to experiment with an exotic state of matter.
Monday is NASA’s fourth attempt at the final prelaunch test for its Artemis 1 Moon rocket.
The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind—known as a white dwarf—is sucking in debris from both the system’s inner and outer reaches, UCLA astronomers and colleagues report today.
This is the first case of cosmic cannibalism in which astronomers have observed a white dwarf consuming both rocky-metallic material, likely from a nearby asteroid, and icy material, presumed to be from a body similar to those found in the Kuiper belt at the fringe of our own solar system.
“We have never seen both of these kinds of objects accreting onto a white dwarf at the same time,” said lead researcher Ted Johnson, a physics and astronomy major at UCLA who graduated last week. “By studying these white dwarfs, we hope to gain a better understanding of planetary systems that are still intact.”
SPACE weather experts are keeping a close eye on an “enormous sunspot” that’s doubled in size in the past 24 hours.
The unstable patch on the solar surface is directly facing Earth so if it bursts it could fling solar flares our way.
A solar flare isn’t expected to hit yet but it could be possible if the sunspot continues to grow and behave in an unstable manner.
The blaze has razed 4 non-scientific structures and flames are near 1 telescope and another that’s being built, officials say.
We’re live now, on Space Renaissance YouTube channel, with Wes Faires, giving a lecture on space law:
The Working Group on Space Resources under the United Nations Committee on Peaceful Uses of Outer Space (UN COPUOS), presents an opportunity for a legally binding instrument to develop under the auspices of the United Nations Committee on Peaceful Uses of Outer Space (UNOOSA), and do so in a manner favorable to space resource utilization for the private sector. The intended result of the Working Group, as stated its 5 years workplan, is to conclude discussions on the development of space resources followed with possible adoption by the United Nations General Assembly as a dedicated resolution or other action. This presentation draws a parallel to a similar scenario with regard to the United Nations Convention on the Law of the Sea (UNCLOS), where a working group on Deep Sea-Bed resources, executed via specific legal channels within the United Nations, led to a legally binding instrument: The 1994 Agreement on Implementation, resulting in a modification of the international framework governing ocean floor minerals.
The avenue utilized for the execution of the 1994 Agreement on Implementation for UNCLOS provides a course for legally binding instrument to develop via the Working Group on Space Resources. Such an instrument could serve to interpret and elaborate on ambiguities within the Outer Space Treaty framework, while avoiding any parallels to the commercially harmful aspects of the top-down governance structure embedded within the International Seabed Authority.
A short bio.
Scorching ‘’hot Jupiters sometimes orbit their parent stars along wonky orbits.
Scorching ‘’hot-Jupiters sometimes orbit their parent stars along wonky orbits. Astronomers are trying to understand why — and if it happens in our own Solar System.
Like many other industries, the space exploration process is also adopting Artificial Intelligence (AI) and robotics to fast-track its mission. This leads us to great lengths and never explored places. Emerging technologies like machine learning and deep learning are organizations working in space programs an opportunity to embrace AI and robotics. Robots help the space exploration process through the mechanical design of planetary rovers, the mechanical design of space manipulators, actuators and sensors of space robots, end-effector/tools of space robots, reconfigurable robots, and robot mobility. Here are some exemplary cases of robotics and AI in space tech.
1. Canadian Space Association launched Dextre, a robotic arm designed to install and replace small equipment such as exterior cameras or the 100-kg batteries used on the Space Station, and to test new tools and robotics techniques.
2. Voyager 1 and Voyager 2, were designed to conduct close-up studies of Jupiter and Saturn, Saturn’s rings, and both Jupiter and Saturn’s largest moon. These robots are still communicating information via the Deep Space Network (DSN) and are presently closer to Pluto than to Earth or the sun.
