What is the new commercial pathway for space?
An exciting new commercial pathway is revolutionizing and opening access to space, fostering America’s new space economy in low-Earth orbit. For the first time, the market is expressing what research can and should be done aboard the microgravity laboratory without direct government funding. The Center for Advancement of Science in Space, or CASIS, manages half of the crew research time via the ISS National Laboratory and is filling the pipeline with a wide variety of commercial research and payloads. More than two-thirds of these projects to date have required zero funding from CASIS, and that trend is increasing. In addition, a significant portion of the commercial research taking place aboard the station is made possible by NanoRacks hardware. The company has invested privately and raised capital to provide laboratory facilities for small payloads, including CubeSats deployed from the space station, that make research faster and more affordable. NASA’s move to purchase commercial cargo resupply and crew transportation to the space station enables U.S. businesses to develop a competitive capability they also can sell as a service to others while freeing NASA resources for deep space exploration. Private sector participation provides a new model for moving forward in partnership with the government.

How do satellites help in illegal fishing?
Satellites can help track and stop illegal fishing by pairing vessel Automatic Identification System (AIS) transponders – which show the location of legal fishing vessels and are legally required to be switched on – with up-to-date satellite imagery, enabling the identification of vessels operating without AIS signals and which are more likely to be engaged in illegal fishing activity.
How does satellite imagery help farmers?
Satellite imagery can tell crop yield on a pixel by pixel basis – enabling farmers to better decide when to add water or fertilizer and when to harvest. By imaging the land using special spectral bands (such as near infra-red) we can develop a vegetation index that represents crop vigour and productivity. Agricultural land represents 37% of the land area of earth and satellites are uniquely capable of collecting this data across such a vast territory. For example, my own company, Planet, images the whole land mass of Earth daily to help with these efforts.
