We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
Signals from Global Navigation Satellite Systems are quite vulnerable. They are exceptionally weak, meaning that any radio noise near their frequency, accidental or malicious, can interfere with reception. I am confident that there are people in every government who understand the problem. The challenge is getting leadership to both understand and act to reduce the risk.
We are the only company capable of delivering 4G and 5G and in the future, 6G broadband speed sufficient for voice calls, voice over LTE, live video calls, streaming, and full Internet access directly to unmodified devices. Simply put, we are the first company in the history of commercial satellite manufacturing to produce satellites of our size and power at scale.
It has been an eventful few months for the Northern Hemisphere atmosphere. An unusually early sudden stratospheric warming episode in late November appears to have factored into a weakened and distorted polar vortex at times in December, likely causing extra waviness in the polar jet stream. This helped fuel extensive intrusions of frigid air into the mid-latitudes, contributing to cold snaps in North America, Europe, and Asia, and priming the atmosphere for disruptive winter storms in January.
Apple's satellite features were originally designed for emergencies, allowing iPhone users to contact emergency services when cellular and Wi-Fi coverage is unavailable. With recent versions of iOS, Apple has expanded those capabilities to include sending and receiving messages via satellite. This makes it possible to stay in touch with friends and family from remote locations where traditional networks do not reach, such as hiking trails, rural areas or offshore locations.
Interactive Quiz ⋅ 9 QuestionsBy Joseph Peart In this quiz, you'll test your understanding of GeoPandas. You'll review coordinate reference systems, GeoDataFrames, interactive maps, and spatial joins with .sjoin(). You'll also explore how projections affect maps and learn best practices for working with geospatial data. This quiz helps you confirm that you can prepare, visualize, and analyze geospatial data accurately using GeoPandas.
On February 28, ships navigating the Strait of Hormuz started appearing on tracking screens in places they couldn't possibly be. They appeared to be sitting on airport runways, parked on Iranian land, and clustered at nuclear power plants. More than 1,100 commercial vessels had their navigation systems scrambled in a single day following US-Israeli airstrikes on Iran, bringing a waterway that handles a fifth of the world's oil exports to a halt.
We are firmly in the era of the satellite constellation—groups of dozens of similar satellites—and are currently entering the era of the mega constellation, wherein groups of thousands of satellites swarm the skies. The clusters of satellites started small, but, like a viral outbreak, they grew almost without us noticing—and now we're dealing with a pandemic.
By the end of the year, Northwood, based in El Segundo, California, had shown the ability to build eight of these Portal arrays a month. And in January the company had deployed operational Portal antennas across two continents. These deployments, which comprise an area of 8 to 15 meters, have the equivalent capability of a 7-meter parabolic dish, said Griffin Cleverly, co-founder and chief technical officer of Northwood.
Planet Labs ( ) has been on a tear, soaring 388% in 2025 and up another 96% since reporting earnings one month ago. The stock is up an incredible 811% from its 52-week low of $2.79 per share. While it has been winning significant government contracts, such as yesterday's announcement that it won a nine-figure contract from the Swedish government, which drove the stock 12% higher, PL is unprofitable and likely won't be for some time.
Now say you want to run some modest AI stuff. That's a bigger job, so let's scale up our cubical computer with edges twice as long as before. That would make the volume eight times larger (2 3), so we could have eight times as many processors, and we need eight times as much power input-2,400 watts. However, the surface area is only four times (2 2) larger, so the radiative power would be about 4,000 watts.
