The Viettel-1 LEO communication satellite orbits in Low Earth Orbit (LEO). A high-angle, wide shot shows the Viettel communication satellite deployed against the curvature of the Earth and the black void of space. The spacecraft features two large, rectangular multi-junction solar arrays extended to the sides, reflecting intense sunlight. A prominent, high-gain gold-mesh parabolic antenna is positioned at the base, designed for Direct-to-Device (D2D) 5G-Advanced connectivity. The main bus is wrapped in silver and gold multi-layer insulation (MLI), prominently displaying the Viettel corporate logo as it provides ubiquitous network coverage to remote regions during the Mobile World Congress (MWC) in Barcelona, Spain, on March 5, 2026.

The China Mobile LEO Test Satellite (Model 1), a cornerstone of the company's Direct-to-Device (D2D) and NTN (Non-Terrestrial Network) strategy, is showcased at MWC 2026. The model features a prominent large-aperture deployable mesh parabolic antenna, designed to provide high-gain connectivity for 5G-Advanced and early 6G signals. This satellite is part of a constellation that aims to achieve ''ubiquitous connectivity,'' allowing standard smartphones to maintain data and voice links in remote areas, oceans, and during natural disasters by bridging space-based infrastructure with terrestrial networks during the Mobile World Congress (MWC) in Barcelona, Spain, on March 4, 2026.

C/2020 F3 NEOWISE or Comet NEOWISE is seen over the night sky of the Black sea tow of Varna, some 450 kms (260 miles) north-east of the Bulgarian capital Sofia. Comet NEOWISE is a retrograde comet with a near-parabolic orbit discovered on March 27, 2020, by astronomers using the NEOWISE space telescope. At that time, it was a 10th-magnitude comet, located 2 AU away from the Sun and 1.7 AU away from Earth.
