With the proliferation of massive explorations on Lunar Far-side Surface (LFS), deployments of scientific infrastructures have drawn substantial attention with the aids of relay satellites for the ...

This paper presents a complete solution to the problem of attitude determination and control for satellites in elliptical orbits. Specifically, it shows how to create the orbital mechanics, account ...

A fascinating glimpse into how a solar system like our own is born has been revealed with the detection of planet-forming ...

The SEU rates of 65nm SRAM and 0.18μm SRAM on orbits are experimentally studied. SEUs are tested with heavy ions, high energy protons and low energy protons by accelerator. The SEU rates induced by ...

This study is considered several Polar Earth Orbits (PEO) models and their probable costs for Search and Rescue (SAR) and determination MSS solutions. The practical usage of Low PEO constellation is ...

Astronomers have witnessed a planet causing eruptions on its parent star. The discovery, published in Nature, could reshape ...

In this study, we present combined methods to optimize the TianQin orbits so that a set of 5-year stability requirements can be met. Moreover, we discuss slow long-term drift of the detector pointing ...

Reflected global navigation satellite system (GNSS) signals from Earth surface can be received by receivers at low Earth orbit for the remote sensing of geophysical parameters. While the technique has ...

The European Space Agency (ESA) has selected Rocket Lab Corporation to launch a dedicated Electron mission, marking the first time the company will deploy satellites for ESA’s next-generation ...

This article investigates the reconfiguration optimization of the formation flying in elliptical orbits. Based on the Tschauner–Hempel equations, the time-varying system has been reduced to a ...

Here’s what to expect from Project Kuiper’s first full-scale satellite launch United Launch Alliance will send 27 Kuiper satellites into low Earth orbit as we begin a full-scale deployment of our ...

According to the latest studies led by Heidelberg University astronomers, low-mass stars quite often host Earth-like planets. Data collected as part ...
