Last Week in Earth Observation: August 28, 2023

Edge computing, methane detection, Antarctic sea ice levels and penguins, demystifying the process of converting EO data into insights and more

Welcome to a new edition of ‘Last Week in Earth Observation, containing a summary of major developments in EO from last week and some exclusive analysis and insights from TerraWatch.

In this edition: Edge computing, methane detection, Antarctic sea ice levels and penguins, demystifying the process of converting EO data into insights and more


Four Curated Things

Major developments in EO from the past week


1. Contractual Stuff: Funding, Contracts and Deals 💰

My take: Any company that is launching new EO satellites will have to inevitably include edge computing (aka on-orbit data processing) into their plans - not only because of the technological progress in the domain, but also because of the operational efficiency and user experience edge computing promises to offer.

So, being a new entrant in the already-crowded EO market, Sidus Space needed to differentiate itself. This acquisition allows Sidus to not only offer multi-sensor data, but also along with on-orbit computing capabilities. For more on edge computing, stay tuned for the exclusive deep-dive this week!

5. Demystifying the Process of Converting EO Data into Insights

As EO continues to increasingly enable impactful societal, economic and environmental decisions, it becomes increasingly important to understand what goes on behind the hood. The figure below is an attempt to demystify the process of translating EO data into insight.

Yes, some end-users of EO do not really care about how the insights are derived, but commercial EO-derived products are increasingly being used to make crucial decisions such as individuals deciding where to buy property, organisations identifying the climate risk for their assets, governments monitoring the level of wildfire threat for a region etc.

As the commercial EO industry continues to grow and increasingly plays a part in our lives, it might be a good time to start talking about the “black-box problem” in EO, especially as EO-based commercial applications become a fundamental part of the lives of individuals, businesses and governments.

As much as we focus on the role of commercial EO in offering insights to solve a specific market problem, it is equally, if not more, important to be able to fully understand how the insights were derived. Whether it is through continued peer-reviewed publications, complete transparency through an open-source model or simply letting the market decide, that remains to be seen.

6. Marine Heat Waves

The figure below from NASA shows sea surface temperature anomalies as of August 21, 2023, when many areas of the oceans were more than 3°C (5.4°F) warmer than normal. It is derived from measurements of sea surface temperatures from multiple NASA, NOAA, and international satellites, as well as ship and buoy observations.

The average sea surface temperatures around the globe have recorded the highest levels since record keeping began. Scientists have identifed two main factors driving the records: El Niño developing in the Pacific and long-term global warming that has been pushing ocean temperatures steadily upward almost everywhere for a century.
