MOSCOW – Scientists at Rosatom have unveiled a plasma electric rocket engine that is claimed to be capable of propelling spacecraft to Mars in just one to two months. As reported by Russia’s Izvestia newspaper, unlike traditional rocket engines that rely on fuel combustion, this innovative propulsion system utilizes a magnetic plasma accelerator and promises to significantly reduce interplanetary travel time, Interesting Engineering reported. “A plasma rocket motor is a type of electric motor.

WASHINGTON DC – As NASA looks toward long-term lunar missions, a few problems have arisen — specifically, how to create less trash in space and what to do with the trash that people create. That’s why the US space agency started the LunaRecycle Challenge. This challenge is a two-phase competition, NASA says, focused on the design and development of recycling solutions that both reduce solid waste and improve the sustainability of longer-term lunar missions.

The detection of the redshifted 21 cm emission line from neutral Hydrogen during the Epoch of Reionization (EoR) is one of the main goals of (current and upcoming) low-frequency radio telescopes such as the Low Frequency Array (LOFAR; van Haarlem et al. 2013), the Murchison Widefield Array (MWA; Tingay et al. 2013), the Giant Metrewave Radio Telescope EoR experiment (GMRT; Paciga et al. 2013), the Hydrogen Epoch of Reionization Array (HERA; DeBoer et al.

We present a Bayesian inference method to characterise the dust emission properties using the well-known dust- correlation in the diffuse interstellar medium at Planck frequencies ν ≥ 217 GHz. We use the Galactic map from the Galactic All-Sky Survey (GASS) as a template to trace the Galactic dust emission. We jointly infer the pixel-dependent dust emissivity and the zero level present in the Planck intensity maps.

Recent measurements of the ionizing photon mean free path (MFP) based on composite quasar spectra may point to reionization ending at z < 6. These measurements are challenging because they rely on assumptions about the proximity zones of the quasars. For example, some quasars might have been close to neutral patches where reionization was still ongoing (‘neutral islands’), and it is unclear how they would affect the measurements.

Physical properties of ten millimeter-sized meteoroids from the Southern Delta Aquariids (SDA) shower are derived using optical observations from the Canadian Automated Meteor Observatory between 2020 and 2023. The meteors are found to ablate in two distinct erosion stages, the second stage showing a single, bright leading fragment. Our modelling interprets these observations as evidence for equal masses of compact grains embedded in a porous, low density matrix.

Counter-rotating stellar discs (CRDs) are characterized by the presence of two stellar discs that are co-spatial in one galaxy but rotating in opposite directions. Such a feature was first discovered in NGC 4550 by absorption line analyses (Rix et al. 1992; Rubin, Graham & Kenney 1992). Moreover, 2σ feature was proposed by Krajnović et al.

Dry permafrost is a challenging environment for microbial life due to the cold, dry, and often oligotrophic conditions. In 2016, Elephant Head, Antarctica was confirmed as the second site on Earth to contain dry permafrost. It is geographically distinct from the McMurdo Dry Valleys where dry permafrost has been studied previously. Here we present the first study of the microbial activity, diversity, and functional potential of Elephant Head dry permafrost.
