Earth planning date: Friday, October 13, 2023: It's been an exciting week in space - Conor already mentioned the news from OSIRIS-REX on Wednesday and just before I logged on for my shift this morning the Psyche spacecraft launched. But the week isn't over and weekends on Mars have lots of room for excitement. Wednesday's pre-drilling tests on target 'Sequoia' (shown in the image above) mo

An instrument designed and built by Lawrence Livermore National Laboratory (LLNL) researchers departed Earth last week on a two-billion-mile, nearly six-year journey through space to explore a rare, largely metal asteroid. The Livermore high-purity germanium (HPGe) gamma-ray sensor is an essential part of a larger gamma-ray spectrometer (GRS) built in collaboration with researchers from Jo

Earth planning date: Monday, October 16, 2023: We are just at the first steps of the next drilling campaign, as regular readers of this blog will certainly have spotted already. The last plan had the preload test, that little dent we make into the rocks to gauge how both the rock and the rover's arm will react to the pressures and stresses of the drilling. It's a good forecast, but rocks are nat

Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics. If gamblers, investors and quantum experimentalists could bend the arrow of time, their advantage would be significantly higher, leading to significantly better outcomes. Researchers at the University of Cambridge have shown

One of the most exciting findings from NASA's Dawn mission is that Ceres, the largest object in the asteroid belt that lies between Mars and Jupiter, hosts complex organics. The discovery of aliphatic molecules, which consist of carbon and hydrogen chains, in conjunction with evidence that Ceres has abundant water ice and may have been an ocean world, means this dwarf planet might have once harb

Since NASA's Lucy spacecraft first imaged the asteroid Dinkinesh on Sept. 3, 2023, Lucy has traveled over 33 million miles (54 million km) and is now 4.7 million miles (7.6 million km) away from the small asteroid. However, as Dinkinesh continues on its orbit around the Sun, Lucy still has another almost 16 million miles (25 million km) to travel to its meet-up with the asteroid on Nov. 1.

ESA’s navigation testbed vehicle participated in a campaign organised by Norwegian governmental authorities to assess the impact of jamming and spoofing on satnav systems and test innovative technologies for detection and mitigation.

This is a transmission spectrum of the hot gas giant exoplanet WASP-17 b captured by the NASA/ESA/CSA James Webb Space Telescope's innovative Mid-Infrared Instrument (MIRI) on 12–13 March 2023. It reveals the first evidence for quartz (crystalline silica, SiO₂) in the clouds of an exoplanet.

This marks the first time that SiO₂ has been identified in an exoplanet, and the first time any specific cloud species has been identified in a transiting exoplanet.

The spectrum was made by measuring the change in brightness of 28 wavelength bands of mid-infrared light as the planet transited the star. Webb observed the WASP-17 system

The ocean has always been a force to be reckoned with when it comes to understanding and traversing its seemingly limitless blue waters. Past innovations such as deep-sea submersibles and ocean-observing satellites have helped illuminate some wonders of the ocean though many questions still remain. These questions are closer to being answered thanks to the development of the Intelligent Swift Oc
