Imagine a giant vertical railway stretching 100,000 km from the equator, somewhere in the Pacific, straight up into space. Instead of expensive, polluting rockets, the space elevator offers a smooth, slow electric ascent to Earth orbit. This "bridge to the stars" connects a floating Earth platform at 36,000 km to a massive counterweight located 64,000 km farther out. It is held taut by the Earth's rotation.

We are increasingly aware of the impact of space weather on spacecraft in space and, occasionally, on electrical power transmission on Earth, but what about its impact on the Earth's atmosphere? That is exactly the research interest of Professor Pallam Raju, Dean of the Physical Research Laboratory in Ahmedabad, India. Founded in 1947, the PRL is one of India's most prestigious scientific institutions, not least because it was founded by Dr Vikram Sarabhai.

Space Power Ltd, founded in 2019, is developing a novel solution for contactless power delivery using high-intensity lasers to extend the lifespans of ageing satellites in space. I spoke with its founder, Keval Dattani, in Nicosia during Cospar2025.org.

Professor Kai-Uwe Schrogl is a space law expert with experience in many roles, including working with the European Space Agency ESA, the German Federal Ministry for Economic Affairs and as the Director of the European Space Policy Institute (ESPI) in Vienna. In this interview, recorded in Nicosia during cospar2025.org in November 2025, he discusses concerns about increasing commercialisation of space and the lunar surface—specifically, the absence of a universally accepted framework for lunar governance.

Cyprus is a small country with a small population and a small economy. But it has big ambitions in space. In this episode, recorded at Cospar 2025 in Nicosia, George Danos, who has been championing this case for Cyprus for years and can be considered Cyprus's Carl Sagan, explains the rise of Cyprus's space activities in communication services, small satellites, and collaboration with ESA and more.

From centruries of weaving in the state of Kerala in India to automated AI controlled machines weaving Graphene coated fibres in Manchester. A modern day Cottonopolis.

You may have seen the BBC documentary Britain's Greatest Pilot. Yes, he was an outstanding pilot, but there was much more to him than just that. I published extracts from an interview with Captain Eric Brown in April 2011. Much of that interview was not published .. until now.

Just as the Moon was the first stepping stone for our interplanetary exploration, our nearest star, the Alpha Centauri System will inevitably become our stepping stone for our Interstellar Journey. That is in the distance. A new mission, The Toliman Space Telescope, is launching soon will target the Alpha-Centauri System from Earth orbit.

It is December 2034. A spacecraft launched from Earth in July 2028, enters Titan's atmosphere at 5km/s. Around 2 hours later, it softly lands on the surface at less than 1m /s. Over the next three years, NASA's Dragonfly mission, a rotorcraft the size of a small car, will chemically analyse the Titan's atmosphere, ground and a little of its subsurface. It's called Dragonfly

A two-day Breakthrough Discuss conference held on 23rd and 24th April 2025 in Oxford England, took stock of the latest developments through three main sessions: "Forms of Non-Terrestrial Life", "The Nature of Consciousness and Intelligence", and "Detecting Life As We Do Not Know It". Breakthough Discuss was overseen by the Chairman of the Breakthrough Foundation, in this interview Dr Pete Worden. A former Brigadier. General, astrophysicist, professor and director of NASA Ames Research Centre provides an update

The story of Teide-1 (the first brown dwarf to be observed) is the story at the other end of a star's life cycle. That early stage is when stars transition from a huge cloud of dust and gas (billions of km across). to the size of a large planet (150,000 km). This is way smaller than the size of the sun and only a little larger than Jupiter.

On Thursday, 3rd January 2019, some water was added to some seeds in a tiny greenhouse. The seeds, cotton, potato, Rape and Arabidopsis sprouted. This was an experiment fonducted on the lunar surface

A brief but fascinating life and work of Professor Ivan Almar. he and his wife's contributions to asttronautics in Hungary during and after the Soviet era.

Did you know our galaxy (the Milky Way) has a magnetic field? News to me! Dr Vasu Shaw explains how astronomers go about understanding such phenomena. We also speak her fascinating international journey to becoming an astrophysicist.

Its not just cotton, trains and computers that Manchester is known for its innovation but aviation too. Frank Pleszak shares his insights in to the role Manchester played in aviation more than 100 years ago.

In this episode, Professor Rene Breton, originally from Quebec, has been working at the Jodrell Bank Centre for Astrophysics for over a decade. We discuss only a small part of his current research, including how Pulsars may one day be used as a GPS for interstellar travel.

In this episode, Professor Mike Garrett from @jodrellbank, discusses research activities at the #Jodrell Bank Centre for Astrophysics, including international collaborations, Dennis Walsh's work on #GravitationalLensing, and the increased #SETI activities through the #Breakthrough Listen Programme. Topics also include the Square Kilometer Array #SKA, Low-Frequency Array #LOFARtechnology, and the impact of #Brexit on Britain's international research participation.

Moonwalkers: A Journey with Tom Hanks is an immersive audio-visual experience in a unique venue in the centre of London. Written by @alifeofriley and Tom Hanks. Available only in London and only until 13th October 2024

If you want to learn about the life and work of rocket pioneer Hermann Oberth, there is only one place to visit. The Hermann Oberth Space Travel Museum in the German Town of Feucht, near Nurnberg. @OberthMuseum #Oberth

Euclid, a @esa science mission, will shed light on both dark matter and dark energy. It was launched in July 2023 and arrived in its L2 orbit a month later. It has just two instruments which will produce a high-resolution 3-D map of a third of the sky, stretching back 10 billion years during its initial 6-year operational lifetime.
