As Sir Keir Starmer's Labour party basks in a honeymoon period thanks to a Commons super-majority, what are the environmental challenges ahead?

We asked Simon Lewis, professor of global change science at University College London, about the new government's priorities for tackling the climate crisis, transitioning to renewable energy and the Tories' eco report card after 14 years in power.

Meanwhile, four test astronauts are due to complete 378 days living in a Martian habitat simulation.

The space agency's Crew Health and Performance Exploration Analog mission involved four volunteers locked in an environment designed to look and feel like the Red Planet, called Mars Dune Alpha.

The habitat was 3D-printed inside the Johnson Space Center in Houston, with the team undertaking mission operations, including 'Mars walks' and farming, while communication with the outside world was only via external ground control.

The test, due to end this weekend, is meant to calculate diet, exercise and health requirements for future Mars missions.

Plus, space scientists at Edinburgh's Heriot-Watt University are working on a major new project hunting exoplanets in the solar system.

We hear from about their development of an "astrocomb" helping the South African Large Telescope project, with Richard McCracken, associate professor and lasers expert.
