Why do we study Mars? What missions have been there? How do we plan to explore this intriguing world in the future? Quench your curiosity with this educational infographic on the Red Planet!

For thousands of years, Mars aka the Red Planet, has fascinated skywatchers from countless civilizations and cultures, leading some to speculate that it was a lush world full of life. However, the exploration of Mars has proven to be quite the contrast, instead exhibiting a dry and inhabitable world utterly devoid of life. Despite this, scientists and engineers from around the world have learned quite a bit from our planetary neighbor with the countless robotic explorers sent there, including flybys, orbiters, landers, and rovers.

Through this, we have gained incredible insight into the ancient history of Mars and whether life might have existed there long ago. In the future, as humanity looks to return the first samples from Mars and land humans on the Red Planet’s surface, we will continue to learn more about this fascinating world and whether it could have, or currently, hosts life as we know it.

Water plays a crucial role in human survival on the lunar surface, thus attracting extensive research attention. Prof. Wang Junqiang’s team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has recently developed a new method of massive water production through a reaction between lunar regolith and endogenous hydrogen.

Research results of previous lunar explorations, like the Apollo and Chang’E-5 missions, have revealed the widespread presence of water on the moon. However, the water content in lunar minerals is extremely low, ranging from 0.0001% to 0.02%. It remains challenging to extract and utilize water in situ on the moon.

“We used lunar regolith samples brought back by the Chang’E-5 mission in our study, trying to find a way to produce water on the moon,” said Wang. The study was published in The Innovation.

Using a phenomenon known as gravitational lensing, it might be possible to use the sun as a gigantic telescope to peer deep into space.

Thanks to observations by the Solar Occultation in the Infrared (SOIR) instrument on the Venus Express space probe of the European Space Agency (ESA), researchers have discovered an unexpected increase in the abundances of two water molecule variants — H₂O and HDO — and their ratio HDO/H2O in Venus’ mesosphere. This phenomenon challenges our understanding of Venus’ water history and the potential that it was once habitable in the past.

Currently, Venus is a dry, hostile planet. Venus has pressures nearly 100 times higher than Earth and temperatures around 460°C. Its atmosphere, covered by thick clouds of sulphuric acid and water droplets, is extremely dry.

Most water is found below and within these cloud layers. However, Venus may have once supported just as much water as Earth.

Using a novel laser method, scientists mimicked the extreme environments of stars and planets, enhancing our understanding of astrophysical phenomena and supporting nuclear fusion research.

Extreme conditions prevail inside stars and planets. The pressure reaches millions of bars, and it can be several million degrees hot. Sophisticated methods make it possible to create such states of matter in the laboratory – albeit only for the blink of an eye and in a tiny volume. So far, this has required the world’s most powerful lasers, such as the National Ignition Facility (NIF) in California. But there are only a few of these light giants, and the opportunities for experiments are correspondingly rare.

A research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), together with colleagues from the European XFEL, has now succeeded in creating and observing extreme conditions with a much smaller laser. At the heart of the new technology is a copper wire, finer than a human hair, as the group reports in the journal Nature Communications.

Scientists have measured the magnetic moment of the muon to unprecedented precision, more than doubling the previous record.

Physicists from the Muon g-2 Collaboration cycled muons, known as “heavy electrons,” in a particle storage ring at Fermilab in the United States to nearly the speed of light. Applying a magnetic field about 30,000 times stronger than Earth’s, the muons precessed like tops around their spin axis due to their own magnetic moment.

As they circled a 7.1-meter diameter storage ring, the muon’s magnetic moment, influenced by virtual particles in the vacuum, interacted with the external magnetic field. By comparing this precession frequency with the cycling frequency around the ring, the collaboration was able to determine the muon’s “anomalous magnetic moment” to a precision of 0.2 parts per million.

Studies of gravity variations at Mars have revealed dense, large-scale structures hidden beneath the sediment layers of a lost ocean. The analysis, which combines models and data from multiple missions, also shows that active processes in the Martian mantle may be giving a boost to the largest volcano in the solar system, Olympus Mons. The findings have been presented this week at the Europlanet Science Congress (EPSC) in Berlin by Bart Root of Delft University of Technology (TU Delft).

Integrating diverse data sources with different formats and standards also presents considerable challenges. Promoting open-source platforms and standardizing data formats are critical for facilitating data exchange within the space industry.

Robbie Robertson, CEO of Sedaro, identifies the main barrier to integrating digital twin technology as a cultural shift rather than technical feasibility. “The most substantial limitation is the change involved in adopting this new approach,” he explains. Overcoming the inertia of legacy tools to build a future-proof system is crucial. Additionally, addressing the shortage of skilled professionals is vital. Collaborations with institutions like MIT’s Aeronautics and Astronautics Department and robust educational initiatives are essential to developing the next generation of engineers and scientists equipped to manage digital twins.
