Using the repurposed equipment, a team including Imperial College London researchers have measured parts of the Martian atmosphere that were previously impossible to probe. This includes areas that can block radio signals if not properly accounted for—crucial for future Mars habitation missions.
The results of the first 83 measurements, analyzed by Imperial researchers and European Space Agency (ESA) colleagues across Europe, are published today in the journal Radio Science.
To achieve this, ExoMars’ Trace Gas Orbiter (TGO) teamed up with another ESA spacecraft orbiting the red planet: Mars Express (MEX). The two craft maintain a radio link, so that as one passes behind the planet, radio waves cut through the deeper layers of the Martian atmosphere.
Researchers demonstrate a method to control electroosmotic flow in nanopores without altering the constriction, potentially improving both capture and sensing capabilities.
On July 5, 2024, at around 1 a.m., Earth reached its farthest point from the Sun, known as aphelion. This annual event raises an intriguing question: why are we experiencing summer heat when our planet is at its greatest distance from the Sun?
Understanding Aphelion

An archaeological team in Venezuela has uncovered 20 ancient rock art sites in Canaima National Park in the southeastern part of the country, consisting of both pictograms and petroglyphs, estimated to be about 4,000 years old.
This discovery reveals a previously unknown culture, even though similar rock art has been found elsewhere in South America.
The newfound rock art, referred to as pictograms, was painted in red and featured geometric shapes such as dotted lines, rows of X’s, star-shaped patterns, and interconnected straight lines. Additionally, there are simple depictions of leaves and stick figure drawings of people. Some images, known as petroglyphs, were incised into the rock and exhibit similar geometric designs.
Ways to interact with virtual versions of our deceased loved ones are now a possibility – but there’s a raft of ethical and emotional challenges involved.
Renewable generation should be around 50 per cent of supply on Australia’s main grid by July, 2026, although it might be a bit less depending on progress on the second stage of Golden Plains, which will be the country’s biggest wind farm – at least for a time – when complete.
To get to 80 per cent by 2030 will partly depend on what happens to demand. If demand is flat, then capacity capable of supplying around 67 terawatt hours (TWh) a year will be needed. After allowing for rooftop solar, I reckon that equates to about 25 gigawatts of new capacity, maybe a bit more.
That’s a heck of an ask, but in my opinion still possible and broadly in line with the objectives and scale of the Capacity Investment Scheme (CIS). I’ll have more to say on the role of the CIS once I get round to talking about ITK’s price forecasts, but that can wait. We’re talking capacity and output in this not.
