Solar Cycle 25 is Exceeding Predictions and Showing Why We Need the GDC Mission

This is the solar maximum I was talking about. Happening in 2025 on earth.


December 2019 marked the beginning of Solar Cycle 25. The Sun’s activity has quickly ramped up and even though we haven’t reached peak levels in this cycle, the Sun’s activity is already exceeding predictions. Solar events will continue to increase as we near solar maximum in 2025, and our lives and technology on Earth, as well as satellites and astronauts in space, will be impacted.

NASA’s Heliophysics Division is developing a mission that will provide crucial advances in our understanding of the ionosphere-thermosphere (I-T) system – the Geospace Dynamics Constellation (GDC). This mission will provide the first coordinated global-scale observations of the I-T region, where the effects of solar activity are often seen. The I-T region is a part of Earth’s upper atmosphere that extends up to about 400 miles altitude and includes low-Earth-orbit, where the International Space Station and many commercial and governmental satellites reside. The I-T system is a region that affects our technological society in many ways, from creating interference in radio signals to generating large electric currents in power distribution systems. The GDC mission’s study of the global, coupled system will enable dramatic improvements in our space weather models, which will lead to the mitigation of negative effects on space-based, air-based, and ground-based assets.

During the Sun’s natural 11-year cycle, the Sun shifts from relatively calm to stormy, then back again. At its most active, called solar maximum, the Sun is freckled with sunspots and its magnetic poles reverse. (On Earth, that would be like if the North and South Poles flip-flopped every decade.) During solar minimum, on the other hand, sunspots are few and far between. Often, the Sun is as blank and featureless as an egg yolk.

Unveiling Cosmic Secrets and Earth’s Mysteries With NASA’s Latest CubeSat Fleet

NASA ’s CubeSat Launch Initiative (CSLI) is sending four CubeSats to the International Space Station to advance space-based technologies in solar power, gamma-ray burst detection, and water monitoring. Developed in collaboration with universities and NASA, these satellites aim to enhance our understanding of cosmic phenomena and Earth’s environmental dynamics.

NASA’s CubeSat Launch Initiative is sending a group of four small satellites, called CubeSats, to the International Space Station (ISS) as ELaNa 51 (Educational Launch of Nanosatellites). These small payloads have been developed by NASA and universities and will be deployed from low Earth orbit.

Once circling Earth, the satellites will help demonstrate and mature technologies meant to improve solar power generation, detect gamma-ray bursts, determine crop water usage, and measure root-zone soil and snowpack moisture levels.

Lockheed Martin eyes growth in satellite business through partnerships

WASHINGTON — Lockheed Martin is looking to team up with more commercial space companies as it aims to stay ahead of the curve in areas like intelligence, surveillance, communications, and small satellites, a senior executive said March 19.

“We’re looking for strategic partners,” said Robert Lightfoot, president of Lockheed Martin Space. “We’re interested in talking with anyone who has an advantage in those areas from a space perspective.”

Lightfoot spoke with SpaceNews at the Satellite 2024 conference.

Building The World’s Most Powerful Satellites w/ Will Marshall | EP #90

In this episode, Peter and Will dive into satellite technology, what it takes to create a company like Planet, and its effect on ecosystems across the world.

Will Marshall, Chairman, Co-Founder, and CEO of Planet, transitioned from a scientist at NASA to an entrepreneur, leading the company from its inception in a garage to a public entity with over 800 staff. With a background in physics and extensive experience in space technology, he has been instrumental in steering Planet towards its mission of propelling humanity towards sustainability and security, as outlined in its Public Benefit Corporation charter. Recognized for his contributions to the field, Marshall serves on the board of the Open Lunar Foundation and was honored as a Young Global Leader by the World Economic Forum.

SpaceX to sell satellite laser links that speed in-space communication to rivals

WASHINGTON, March 19 (Reuters) — SpaceX has started selling satellite lasers, which are used for speedy in-space communications, to other satellite firms, company President Gwynne Shotwell said at a conference on Tuesday.

SpaceX’s thousands of Starlink satellites in low-Earth orbit use inter-satellite laser links to pass data between one another in space at the speed of light, allowing the network to offer broader internet coverage around the world with fewer ground stations.

Shotwell, speaking on a panel at the Satellite industry conference in Washington, said SpaceX as a supplier will sell that technology to other companies.

How rerouting planes to produce fewer contrails could help cool the planet

Last summer, Breakthrough Energy, Google Research, and American Airlines announced some promising results from a research collaboration, as first reported in the New York Times. They employed satellite imagery, weather data, software models, and AI prediction tools to steer pilots over or under areas where their planes would be likely to produce contrails. American Airlines used these tools in 70 test flights over six months, and subsequent satellite data indicated that they reduced the total length of contrails by 54%, relative to flights that weren’t rerouted.

There would, of course, be costs to implementing such a strategy. It generally requires more fuel to steer clear of these areas, which also means the flights would produce more greenhouse-gas emissions (more on that wrinkle in a moment).

More fuel also means greater expenses, and airlines aren’t likely to voluntarily implement such measures if it’s not relatively affordable.
