Swarm of laser-sail spacecraft leaving the solar system. Credit: Adrian Mann A final recommendation Dr. Parkin made in the paper was the inclusion of a distributed algorithm that would allow the spacecraft to function in tandem and with a degree of autonomy, each one responsible for mapping a...
The goal of the $150 million mission is to study the asteroid in depth, from space and from the surface, and bring samples back to Earth in late 2020. Such samples could shed additional light on the solar system’s formation and life’s chemical building blocks. This mission follows up o...
Simulation of the trajectories of the probes Voyager 1 and Voyager 2, Pioneer 10 and Pioneer 11, that now they are leaving the Solar System.
Over time, the sun pushes lighter elements out of the atmosphere, leaving the heavier ones behind. Scientists already have gained a pretty firm understanding of the past deuterium-hydrogen ratio by examining known Martian meteorites and older Martian minerals that NASA rovers probed on the surface,...
At the time of accretion, part of the DDDM might be in the form of atomic-like states made of heavy and light DM. These dark atoms will become fully ionized due to shock heating during the virialization of the halo leaving a population of free X and C fermions. This dark plasma cools...
Star escapes ravenous supermassive black hole, leaving behind its stellar partner SpaceX Falcon 9 rocket launches Starlink satellites on record-breaking 25th flight (video, photos) NASA Solar Dynamics Observatory back online after 2024 data center flood What is the US Space Force doing in Greenland...
Heavy metal (HM) pollution is a major global concern. Carbon dots (CDs) have demonstrated unique properties as sensing platforms for HMs detection. This review summarizes the progress made in recent years in fluorescence methods to determine HMs and thei
Pending on their mass PBHs can survive to the present time, being a specific form of dark matter (see e.g., [51]), or evaporate by Hawking mechanism [52], leaving observable effects of products of their evaporation. If predicted effect of PBHs contradicts the observational data, it provide...
Because the sink node maintains a list of wireless sensor nodes to support their joining and leaving, the WSNs are robust and scalable. to save energy. The sink node gathers local information from stationary nodes and mobile nodes after distributed processing, monitoring the water quality ...
