The Moon just brushes the umbral shadow of the Earth during Tuesday night’s partial lunar eclipse.

Mars has always held a special place in our hearts, likely from hints over the decades of perhaps finding signs of life, albeit fossilised and primitive. It’s been the subject of study from telescopes and space missions alike, most notably ESA’s Mars Express which has been observing the red planet for 20 years. Over the two decades of observation it has studied an amazing variety of atmospheric phenomenon which have now been catalogued in a new ‘Cloud Atlas.’ Many will be familiar to sky watchers on Earth but some are very different. 

Continuous human habitation of the Moon is the state aim of many major space-faring nations in the coming decades. Reaching that aim requires many tasks, but one of the most fundamental is feeding those humans. Shipping food consistently from Earth will likely be prohibitively expensive shortly, so DLR, Germany’s space agency, is working on an alternative. This semi-autonomous greenhouse can be used to at least partially feed the astronauts in residence on the Moon. To support that goal, a team of researchers from DLR released a paper about EVE, a robotic arm intended to help automate the operations of the first lunar greenhouse, at the IEEE Aerospace conference in March.

Of all the mysteries facing astronomers and cosmologists today, the “Hubble Tension” remains persistent! This term refers to the apparent inconsistency of the Universe’s expansion (aka. the Hubble Constant) when local measurements are compared to those of the Cosmic Microwave Background (CMB). Astronomers hoped that observations of the earliest galaxies in the Universe by the James Webb Space Telescope (JWST) would solve this mystery. Unfortunately, Webb confirmed that the previous measurements were correct, so the “tension” endures.

Optical interferometry has been a long-proven science method that involves using several separate telescopes to act as one big telescope, thus achieving more accurate data as opposed to each telescope working individually. However, the Earth’s chaotic atmosphere often makes achieving ground-based science difficult, but what if we could do it on the Moon? This is what a recent study presented at the SPIE Astronomical Telescopes + Instrumentation 2024 hopes to address as a team of researchers propose MoonLITE (Lunar InTerferometry Explorer) as part of the NASA Astrophysics Pioneers program. This also comes after this same team of researchers recently proposed the Big Fringe Telescope (BFT), which is a 2.2-kilometer interferometer telescope to be built on the Earth with the goal of observing bright stars.

Earlier this year, NASA selected a rather interesting proposal for Phase I development as part of their NASA Innovative Advanced Concepts (NIAC) program. It’s known as Swarming Proxima Centauri, a collaborative effort between Space Initiatives Inc. and the Initiative for Interstellar Studies (i4is) led by Space Initiative’s chief scientist, Marshall Eubanks. The concept was recently selected for Phase I development as part of this year’s NASA Innovative Advanced Concepts (NIAC) program.

A team of scientists presented a new gravity map of Mars at the Europlanet Science Congress 2024. The map shows the presence of dense, large-scale structures under Mars’ long-gone ocean and that mantle processes are affecting Olympus Mons, the largest volcano in the Solar System.
