Since 2018, when the NASA InSight Mission deployed the SEIS seismometer on the surface of Mars, seismologists and geophysicists at ETH Zurich have been listening to the seismic pings of more than 1,300 marsquakes. Again and again, the researchers registered smaller and larger Mars quakes. A detailed analysis of the quakes' location and spectral character brought a surprise. With epicentres

A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise consistent with an extended warm and wet climate, not the harsh, frozen landscape that exists today. "What immediately comes to mind as one the most significant points here is that the existence of an o

Building up the lunar settlement is the ultimate aim of lunar exploitation since human's first step on the moon. Yet, limited fuel and oxygen supplies restrict human survival on the moon. Combining photovoltaic and electrocatalysis, the artificial production of hydrocarbon fuels along with oxygen using carbon dioxide and water as the feedstocks has been demonstrably feasible on the earth and kno

When asteroid 596 Scheila collided with an object in the asteroid belt between Mars and Jupiter in December 2010, a fresh layer of material was exposed on the asteroid surface . An international research team observed the spectrum from the asteroid approximately ten years later, to see how space weathering affects the surface over a genuine timescale. Within the uncertainty of the observations,

Seismologists from The Australian National University (ANU) have developed a new method to scan the deep interior of planets in our solar system to confirm whether they have a core at the heart of their existence. The scanning method, which works in a similar way to an ultrasound scan using sound waves to generate images of a patient's body, requires only a single seismometer on a planet's

In today's plan, we got to exercise our combined APXS-MAHLI touch and go capability. Now that our days on Mars are starting a bit earlier thanks to Earth rising earlier in the morning sky, APXS gets a cooler time to operate on days we also drive. So the APXS-MAHLI teams are back to being regular partners in exploration once again. Today's workspace was much like our last one, lumpy and bum

On 24 December 2021, NASA's InSight lander felt the ground shake. Its SEIS seismometer registered a marsquake of magnitude 4. Independently, a 150-metre diameter crater was photographed from orbit by the cameras of the Mars Reconnaissance Orbiter. The camera team was able to determine that it was formed on 24 December, and realised that this was the same day as the reported quake. When the two t

Set for a November launch, the small satellite mission will use lasers to search for water ice inside the darkest craters at the Moon's South Pole. The Moon's poles offer a tantalizing opportunity for human explorers: There may be reservoirs of water ice there that could be purified as drinking water, converted into breathable oxygen, and used as fuel by astronauts. These reservoirs are inside p

AIP is organizing a competition for undergraduate students in the physical sciences to design a spaceborne starshade. The device will orbit Earth, blocking the light from a star and allowing ground-based telescopes to observe extra-solar planets. Since the light coming from a star is likely billions of times brighter than the reflected light from an Earth-like exoplanet, obstructing the li

China launched a Long March 2D carrier rocket on Saturday morning to transport an experimental satellite into space, according to China Aerospace Science and Technology Corp. The State-owned space conglomerate said in a press release that the rocket blasted off at 9:01 am at the Jiuquan Satellite Launch Center in northwestern China and soon sent the Shiyan 20C, or Experiment 20C, into its
