ImpactPixxel Wants to Build a Health Check-Up for Earth. Its Satellites Are Already Doing It.
Conventional satellites see colour. Pixxel's Fireflies see chemistry. A regular satellite tells you a field is green. A Pixxel satellite tells you which parts of that field are stressed, which crops have a fungal infection, and which area is about to fail the harvest. That difference — between seeing a surface and reading what is underneath it — is what hyperspectral imaging does. And it is why Rio Tinto, the NRO, and AstraZeneca are all customers of a company founded by two undergraduates five years ago.
