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

Posted by in categories: education, satellites, solar power, sustainability

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

Posted by in categories: business, satellites, surveillance

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

Posted by in categories: health, satellites, security, sustainability

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

Posted by in categories: internet, satellites

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

Posted by in categories: robotics/AI, satellites

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.

Lumen Orbit emerges from stealth and raises $2.4M to put data centers in space

Posted by in categories: computing, engineering, internet, satellites

Bellevue, Wash.-based Lumen Orbit, a startup that’s only about three months old, says that it’s closed a $2.4 million pre-seed investment round to launch its plan to put hundreds of satellites in orbit, with the goal of processing data in space before it’s downlinked to customers on Earth.

The investors include Nebular, Caffeinated Capital, Plug & Play, Everywhere Ventures,, Sterling Road, Pareto Holdings and Foreword Ventures. There are also more than 20 angel investors, including four Sequoia Scouts investing through the Sequoia Scout Fund. “The round was 3x oversubscribed,” Lumen CEO and co-founder Philip Johnston told GeekWire in an email.

Johnston is a former associate at McKinsey & Co. who also co-founded an e-commerce venture called Opontia. Lumen’s other co-founders are chief technology officer Ezra Feilden, whose resume includes engineering experience at Oxford Space Systems and Airbus Defense and Space; and chief engineer Adi Oltean, who worked as a principal software engineer at SpaceX’s Starlink facility in Redmond, Wash.

SpaceX launches Starlink mission, prepares to undock a Crew Dragon from ISS Monday

Posted by in categories: internet, satellites

SpaceX is closing out the weekend with a pair of planned Falcon 9 launches from Florida and California while also preparing for the undocking of Crew Dragon Endurance from the International Space Station.

The Falcon 9 rocket supporting the Starlink 6–43 mission lifted off from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station at 7:05 p.m. EDT (2305 UTC). It will add 23 Starlink satellites to the growing low Earth orbit constellation.

SpaceX targeting Sunday night for next Falcon 9 rocket launch from Cape Canaveral

Posted by in categories: internet, satellites

In fact, the Space Force’s 45th Weather Squadron predicts 95% odds of “go for launch” weather conditions.

SpaceX announced the Starlink 6–43 launch is targeted for 7:05 p.m. EDT Sunday from Launch Complex 40, with backup opportunities available if needed until 11:03 p.m.

The Falcon 9 rocket will deploy another payload of 23 Starlink broadband satellites into low-Earth orbit, adding to SpaceX’s growing constellation.

Multiple spacecraft tell the story of one giant solar storm

Posted by in categories: particle physics, satellites

April 17, 2021, was a day like any other day on the sun, until a brilliant flash erupted and an enormous cloud of solar material billowed away from our star. Such outbursts from the sun are not unusual, but this one was unusually widespread, hurling high-speed protons and electrons at velocities nearing the speed of light and striking several spacecraft across the inner solar system.

In fact, it was the first time such high-speed protons and electrons—called (SEPs)—were observed by spacecraft at five different, well-separated locations between the sun and Earth as well as by spacecraft orbiting Mars. And now these diverse perspectives on the solar storm are revealing that different types of potentially dangerous SEPs can be blasted into space by different solar phenomena and in different directions, causing them to become widespread.

“SEPs can harm our technology, such as satellites, and disrupt GPS,” said Nina Dresing of the Department of Physics and Astronomy, University of Turku in Finland. “Also, humans in space or even on airplanes on polar routes can suffer harmful radiation during strong SEP events.”
