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.

  • IAMGOLD Shares Plunge 18.8% in 7 Days Amid Valuation Scrutiny
    March 21, 2026, 3:56 PM EDT. IAMGOLD (TSX: IMG) experienced a sharp 18.8% decline over seven days, falling to C$22.10, despite a strong one-year return of 155.5% and a five-year gain of 477%. Market watchers question if the current price fairly reflects value after this pullback. Simply Wall St's discounted cash flow model values IAMGOLD at C$41.16 per share, indicating a 46.3% undervaluation. The model projects free cash flows growing substantially through 2030, painting a positive long-term outlook. However, recent volatility highlights the risk and reward debate as investors reassess the metals and mining company's prospects.
