The smallest flowering plant on Earth might become a nutritious foodstuff for astronauts in the future, as well as a highly efficient source of oxygen. To help test their suitability for space, floating clumps of watermeal – individually the size of pinheads – were subjected to 20 times normal Earth gravity aboard ESA’s Large Diameter Centrifuge by a team from Mahidol University in Thailand.

Our planet is being continuously bathed in radio signals from satnav satellites – which are useful for much more than just navigation. Dedicated space missions acquire these signal reflections to amass valuable environmental information. The shoebox-sized PRETTY CubeSat, flying on Europe’s next Vega launcher, will investigate a new frequency and novel observation angle to better measure the rate of climate change – at the same time as gathering radiation data on its surrounding space environment.

Thanks to their ability to absorb and store carbon dioxide from the atmosphere, forests have long been recognised as a key tool in the fight against climate change – but not all forests are equal. New research based on data from ESA’s SMOS satellite mission has found that, surprisingly, young trees are champions at carbon capture. View the full article

Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over Antarctica is one of the biggest on record. The hole, which is what scientists call an ‘ozone depleting area,’ reached a size of 26 million sq km on 16 September 2023. This is roughly three times the size of Brazil. View the full article

Estonia’s next satellite will fly aboard Europe’s Vega VV23 launcher later this week. While largely designed and built by undergraduate students, the shoebox-sized ESTCube-2 has ambitious goals in mind, including surveys of Estonian vegetation and the first successful in-orbit demonstration of ‘plasma brake’ technology. Deployment of a charged microtether will slow the CubeSat’s orbit, proving the prospect of helping to keep space clear of dangerous debris in the future. View the full article

Spain’s trio of ANSER CubeSats, due to fly on Europe’s next Vega launcher, will fly like a flock of birds in orbit – in more ways than one. Keeping in formation by following their leader, the three shoebox-sized satellite will image Iberian waters as if they are a single standard-sized mission. And they will unfurl wing-like flaps to maintain their relative positions, surfing on the scanty airflow at the top of Earth’s atmosphere. View the full article
