The Most Significant Satellite You've (Probably) Never Heard Of

PBS Space Time

Summary

NASA's Orbiting Carbon Observatory (OCO) program plays a crucial role in monitoring Earth's atmosphere, particularly focusing on carbon dioxide levels. The program, which includes OCO-2 and OCO-3, provides high-resolution data that allows scientists to map CO2 density with remarkable precision. This capability is vital for understanding the sources and sinks of atmospheric carbon and tracking seasonal changes in plant metabolism, which can help predict agricultural yields and assess environmental health.

Despite its successes, the OCO program faces potential budget cuts, with the White House proposing to eliminate funding for its operations. This decision could jeopardize the invaluable data collected over the years, which is essential for climate change modeling and agricultural forecasting. The ability to monitor carbon emissions and plant health could significantly impact food security and economic stability, particularly for rural communities reliant on agriculture.

The OCO satellites have demonstrated unexpected capabilities, such as measuring plant photosynthesis through solar-induced fluorescence, which provides insights into vegetation health and stress levels. This information is critical for predicting droughts and managing crop yields, making the continuation of the program not only beneficial for scientific research but also for global food security and economic resilience.

One of the most important reasons we go to space is to know our own planet better. Today I'm going to tell you about an orbiting facility that literally watches Earth's biosphere breath and grow and die with incredible resolution. I'll talk about its profound existential and economic importance, and about why it's in danger of being lost.

Actually, we have multiple explanations that all predict the same thing. And at first glance, these explanations seem to describe completely different causes. So what is the true connection between light and gravity, or is truth, in fact, entirely relative?Sabine Hossenfelder's episode "Do we travel through time at the speed of light?"https://youtu.be/iBTez-nTKesCheck out the Space Time Merch Storehttps://www.pbsspacetime.com/shopSign up for the mailing list to get episode notifications and hear special announcements!https://mailchi.mp/1a6eb8f2717d/spacetimeHosted by Matt O'DowdWritten by Matt O'Dowd Graphics by Leonardo Scholzer, Yago Ballarini, Pedro Osinski, Adriano Leal and Stephanie FariaGFX Visualizations: Katherine KorneiDirected by Andrew KornhaberAssistant Producer: Setare GholipourExecutive Producers: Eric Brown and Andrew Kornhaber"FREE GMC Motorhome reimagined low poly" (https://skfb.ly/6XxAN) by Karol Miklas is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/by/4.0/).

His whole “nothing travels faster than light” rule seems to ensure that exploration of even the local part of our galaxy will be an excruciating slow. But Einstein also gave us a glimmer of hope. He showed us that space and time can be warped - and so the warp drive was conceived. Just recently, a couple of papers contend that these are not pure science fiction.
