Technical characteristics of Macau Science Satellite-1A

Earth and Planetary Physics
The Macau Science Satellite-1 (MSS-1) is the first space science satellite jointly developed on the Chinese mainland and in Macau. It comprises two satellites, named MSS-1A and MSS-1B, and holds considerable importance in China’s space exploration ...

Analysis for the results of geomagnetic storms measured by Macau Science Satellite-1

Earth and Planetary Physics
Strong flares and/or coronal mass ejections (CMEs) could bring us disastrous space weather, destroy crucial technology in space, and cause a large-scale blackout during some extreme cases.

Controlled growth of ultrathin ferromagnetic β‐MnSe semiconductor

, 2022
Two-dimensional (2D) magnetic crystals with intrinsic ferromagnetism are highly desirable for novel spin-electronic devices. However, the controllable synthesis of 2D magnets, especially the direct growth of 2D magnets on substrate surfaces, is still a ...

Influence of the Eccentric Geomagnetic Dipole on Longitude Variations of Compressional Upstream Wave Amplitudes in the Topside Ionosphere: Results From the MSS‐1A Satellite

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Based on 2‐year magnetic data from the Macau science satellite, we investigate the compressional Pc3‐4 pulsations (between 16 and 100 mHz) driven by upstream waves (UWs). Our results confirm larger UWs amplitudes in the South Atlantic Anomaly (SAA) longitudes, agreeing with previous missions.

Relatively Intense Daytime GNSS Amplitude Scintillations at Middle Latitude Linked With Multi‐Layered Strong Es Structures

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Intense Global Navigation Satellite System (GNSS) amplitude scintillations usually occur in nighttime at low latitudes due to ionospheric plasma bubble irregularities. During daytime at middle latitudes, previous studies found that the sporadic E (Es) layer could lead to GNSS amplitude scintillations, which however, is relatively weak, for ...

Quasi‐Trapped Zebra Stripes: Radial Transport Driven by Dual‐Pulse Electric Fields

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Energetic electron spectra in Earth's inner radiation belt often exhibit regular stripe‐like features, known as “zebra stripes,” which are typically attributed to the drift motion of stably‐trapped electrons disturbed by electric field perturbations.
