Nearly 20 years after the Concorde made its final commercial flight, new efforts are underway to make supersonic passenger travel viable again. Bill Whitaker reports.

“60 Minutes” is the most successful television broadcast in history. Offering hard-hitting investigative reports, interviews, feature segments and profiles of people in the news, the broadcast began in 1968 and is still a hit, over 50 seasons later, regularly making Nielsen’s Top 10.

The Moon awaits. After long decades in which no human being set foot on the lunar surface, we are heading back. And quite soon.

As part of the NASA-led Artemis program, astronauts are returning to the lunar environment as soon as 2024, with a view to ultimately establishing a long-term human presence on the Moon – a place we haven’t seen in person since 1972.

To live and work on the Moon, though, astronauts will need power and plenty of it, and there’s no power grid on the Moon.

Scientists at the University of Birmingham have succeeded in creating an experimental model of an elusive kind of fundamental particle called a skyrmion in a beam of light.

The breakthrough provides physicists with a real system demonstrating the behavior of skyrmions, first proposed 60 years ago by a University of Birmingham mathematical physicist, Professor Tony Skyrme.

Skyrme’s idea used the structure of spheres in 4-dimensional space to guarantee the indivisible nature of a skyrmion particle in 3 dimensions. 3D particle-like skyrmions are theorized to tell us about the early origins of the Universe, or about the physics of exotic materials or cold atoms. However, despite being investigated for over 50 years, 3D skyrmions have been seen very rarely in experiments. The most current research into skyrmions focuses on 2D analogs, which shows promise for new technologies.

Humans haven’t set foot on the Moon since the Apollo 17 mission in 1972. By the time they return to our cosmic neighbor by around 2025, the exploration landscape will be very different due to wide-ranging technological advances.

In a bid to further accelerate the technology that will power future lunar missions, NASA, alongside the Department of Energy (DOE) 0, has put out a press statement calling for companies to help it develop nuclear energy solutions.

Terraforming Mars is one of the great dreams of humanity. Mars has a lot going for it. Its day is about the same length as Earth’s, it has plenty of frozen water just under its surface, and it likely could be given a reasonably breathable atmosphere in time. But one of the things it lacks is a strong magnetic field. So if we want to make Mars a second Earth, we’ll have to give it an artificial one.

The reason magnetic fields are so important is that they can shield a planet from solar wind and ionizing particles. Earth’s magnetic field prevents most high-energy charged particles from reaching the surface. Instead, they are deflected from Earth, keeping us safe. The magnetic field also helps prevent solar winds from stripping Earth’s atmosphere over time. Early Mars had a thick, water-rich atmosphere, but it was gradually depleted without the protection of a strong magnetic field.

Unfortunately, we can’t just recreate Earth’s magnetic field on Mars. Our field is generated by a dynamo effect in Earth’s core, where the convection of iron alloys generates Earth’s geomagnetic field. The interior of Mars is smaller and cooler, and we can’t simply “start it up” to create a magnetic dynamo. But there are a few ways we can create an artificial magnetic field, as a recent study shows.
