Beaming the Watts Down: NASA × Ascent Solar’s Thin-Film Array Sets the Stage for Space-to-Earth Power Transmission

Beaming the Watts Down: NASA × Ascent Solar’s Thin-Film Array Sets the Stage for Space-to-Earth Power Transmission

Ascent Solar signed a 12-month agreement with NASA in June 2025 to develop thin-film PV arrays for power beaming. Caltech’s SSPD-1 tested orbital power beaming in mid-2023, but end-to-end efficiency remains extremely low. Ascent’s CIGS modules, used on NASA’s Psyche probe, target over 17% efficiency and weigh about 10 grams per panel. Large ground farms and strict beam-control are required for safety and regulation.

  • Constellation Energy's Geothermal Expansion Tests Stock Valuation Amid Pullback
    June 8, 2026, 4:13 PM EDT. Constellation Energy (NasdaqGS:CEG) has completed a 25 MW geothermal expansion at The Geysers, supporting California's renewable goals and building on earlier projects. The unit Calpine, acquired for US$16.4 billion, drives this green energy push. Despite this, Constellation's stock price has dropped 30.4% year-to-date and 14.5% over 12 months, reflecting recent market volatility after a 177.4% rise in three years. Shares traded at US$254.83, about 31% below analysts' US$367.12 target, and 47.6% below estimated fair value per Simply Wall St. Investors should monitor how this capacity and renewables affect earnings, leverage, and the company's longer-term cash flow amid high debt and one-off expenses.
