Russia Successfully Tests Trajectory Correction Systems for New Express‑RV Satellites
Russia's "Roscosmos" agency reported successful trials of trajectory correction systems for its new Express‑RV satellites, confirming the technology's readiness for space deployment.
Test details
Engineers at Ryshetnyov, a subsidiary of the agency, conducted simulated runs replicating the operation of onboard thrusters under real space conditions. The results showed every component performed excellently and met the required technical specifications. Following the success, production of the standard system will commence along with expanded testing.
Project background
The new Express‑RV satellites are intended to deliver continuous communications to unmanned aircraft operating in polar regions, especially the Arctic, bolstering Russia's comprehensive space coverage. This trial is part of a broader effort to modernize Russia's space infrastructure.
The achievement underscores Russia's progress in space technology and opens new possibilities for communications in harsh environments.

Perseverance Rover Uncovers Ruby-Forming Mineral on Mars for the First Time
A research team led by Ann Uliel from Los Alamos National Laboratory announced that the Perseverance rover discovered corundum, the primary component of rubies, in three rocks near the Jezero crater on Mars. The mineral contains chromium, which gives rubies their red color, despite the surrounding rocks being rich in plagioclase, which typically consumes the aluminum needed for its formation. Scientists hypothesize that the heat and pressure from an ancient impact caused its appearance in this chemically uneven environment.
