There is a lot now being talked and written about the success of Apollo 11, and the Apollo space programme, half a century ago. The BBC podcast 13 minutes to the moon is fantastic.

The TV pictures of Neil Armstrong clambering down the ladder of the Apollo 11 Lunar Excursion Module and taking the first steps by a human on the Moon’s surface are rightly iconic, though rather fuzzy. Most people seem to think that those images were received by the radio telescope at Parkes in New South Wales, largely because that was what … Read More

The name of Michael Faraday is well-known in science, for his pioneering work in both chemistry and physics (in particular electricity and magnetism; hence the name of the SI unit of capacitance, the farad). As a postgraduate student at the University of Canterbury I spent many hours working on experimental radio receivers sat inside a large metallic box … Read More

The Islamic fast of Ramadan has come to an end, marking the beginning of the tenth month of the religion’s twelve-lunation year and therefore Eid al-Fidr, the ‘Festival of Breaking the Fast’.

Three nations have so far landed spacecraft on the Moon: the USA, the Soviet Union/Russia, and China. A fourth nation, Israel, has attempted to join this club, but its probe (named Beresheet) … Read More

Ian Crawford, UCL The search for life elsewhere in the universe is one of the most compelling aspects of modern science. Given its scientific importance, significant resources are devoted to this young science of astrobiology, ranging from rovers on Mars to telescopic observations of planets orbiting other stars. The holy grail of all this activity would be … Read More

By Professor Richard Easther This week, the University of Auckland (where I work) announced it is joining the Large Synoptic Survey Telescope collaboration. So what is the LSST, what will it do, and why are we so excited about it? Firstly, the LSST is, as the name suggests, a telescope. Currently under construction in the Chilean Andes, it is scheduled to see “first light” in … Read More

By Morgan Saletta, University of Melbourne Planetary Resources, a company hoping to make asteroid mining into a trillion dollar industry, earlier this year unveiled the world’s first 3D printed object made from bits of an asteroid. 3D printing, and additive manufacturing processes more generally, have made many advances in recent years. Just a few years … Read More

David Rothery, The Open University China’s space agency has announced plans to become the first to land on the far side of the moon, which is always hidden from us – a tricky task given that it is not possible to communicate directly with Earth from there. But if successful, the mission could shed light on … Read More
