NASA Loses Contact With Critical MAVEN Mars Orbiter: What the Sudden Silence Means for Future Missions

NASA Loses Contact With Critical MAVEN Mars Orbiter: What the Sudden Silence Means for Future Missions

NASA lost contact with the MAVEN Mars orbiter on December 6, 2025, after it slipped behind the planet during a routine orbit. The spacecraft, in service since 2014, has not responded to repeated attempts to re-establish communication. As of December 11, engineers are still investigating the cause and have not regained contact. MAVEN remains officially classed as lost-signal.

NASA Warns Starlink-Style Satellite Megaconstellations Could Contaminate Nearly All Future Space Telescope Images

A peer-reviewed Nature study led by NASA warns that satellite megaconstellations could contaminate nearly all images from upcoming space telescopes and about 40% of Hubble’s images by the late 2030s. The forecast assumes up to 560,000 satellites in low-Earth orbit, with some missions expected to see over 96% of exposures affected by satellite trails.

  • Crude Oil Surge Boosts Ethanol and Sugar Prices Amid Production Shifts
    May 21, 2026, 2:36 PM EDT. Crude oil prices rose over 2%, driving gains in ethanol and sugar markets. July New York sugar futures climbed 0.95%, supported by strong crude oil. Higher oil values encourage sugarcane mills to produce more ethanol, reducing sugar output. The International Sugar Organization forecasts a record 182 million metric tons (MMT) sugar crop for 2025/26 but anticipates a drop to 180 MMT in 2026/27, with a potential deficit due to El Niño impacts on key producers like India and Thailand. Brazil's sugar production estimates are lowering amid increased ethanol focus, with Citigroup projecting 39.5 MMT for 2026/27, below official numbers. India's export ban and production shifts contribute to tightening supplies. Market watchers also highlight significant export growth from Thailand, adding complexity to price dynamics.
