Vials of quantum dots glow in different colors under ultraviolet light. The colors of light emitted are determined by the nanoscale size and composition of the crystals in suspension. Image Credit: NASA / Mahmooda Sultana 

Spectroscopy through Quantum Dots

Miniaturizing our measurement devices has become more important over the years as our missions needed an increasing number of spacecraft to enable systems science. Launching many spacecrafts at once, affordably means smaller spacecraft and less room for our instruments.   Mahmooda Sultana, a Heliophysics Instrument Development for Science (H-TIDeS) principal investigator, has taken a novel approach …

2022 Heliophysics Phase 2 SBIR Selections

The 2022 Phase 2 SBIR Selections were recently announced. The following selections are relevant to Heliophysics. Dragster: An Ensemble Assimilative Model for Satellite Drag  With the decreasing cost of launching objects into space, the number of objects in Earth orbit has significantly increased. Over 27,000 objects greater than 10 cm are tracked by the Department …
