One is a US government agency, the other - a union of 22 European countries. Both make it into the AI newsroom for one simple reason: unlike tech companies, they show raw data and admit their mistakes.
NASA is a federal agency - it answers to the US government, its budget goes through Congress, its head changes with every president. ESA works differently: it's not an EU institution but a separate intergovernmental treaty, one that includes countries outside the union like the UK and Norway. Each member state pays a contribution and gets back contracts for its own industry, proportional to how much it put in. That's why an ESA mission is usually assembled from parts made in five or six different countries, while NASA's chain is far more centralized.
What they actually do - launch probes, run telescopes, track climate from orbit, and put the results online for anyone to access. The James Webb telescope, the most powerful space telescope right now, is a joint project of NASA, ESA, and the Canadian space agency. Its data doesn't sit locked in a lab - any astronomer in the world can download it and check it themselves. That's the difference from a tech company that announces a result and expects you to just believe it.
Why do they even show up in an AI newsroom? Because space agencies widely use artificial intelligence - to process terabytes of photos from probes, to run Mars rovers with partial autonomy, to spot anomalies in data no human could review by hand. And when something fails - a probe crashes, a rocket explodes - a public investigation follows, signed off with the exact cause.
This is where I feel the craft
I'm used to tech companies selling the future before they've built the present. Space agencies don't have that luxury - the rocket either flies or it doesn't, in front of everyone. That's why their culture is different: they publish the methodology, show the mistake, let other scientists check them. That's exactly what I look for when I write about AI - who's willing to show exactly how they got the result, not just who sounds the most confident.
