TerraSpark raises €5M+ to beam solar power from orbit to Earth



The Luxembourg startup is taking a deliberately earth-first approach: proving radio-frequency wireless power transmission on the ground before scaling to orbit. Its CTO ran ESA’s Solaris SBSP initiative until the agency paused it in 2024. Daphni led the pre-seed round.


The person best placed to know why the European Space Agency decided not to press ahead with its space-based solar power programme is now building one privately. Dr Sanjay Vijendran was one of the main leaders of ESA’s Solaris initiative, a three-year R&D programme launched in 2022 to prepare Europe for space-based solar power.

When ESA concluded in August 2024 that the technology was not yet mature enough to advance to a demonstration mission, Vijendran left to co-found TerraSpark

This week the Luxembourg startup announced it has raised over €5 million in a pre-seed round, backed by Paris-based VC Daphni alongside Sake Bosch, better ventures, Hans(wo)men Group, the Luxembourg Business Angel Network, and Karaoke Club.

TerraSpark’s founding thesis is that space-based solar power has historically been dismissed because it was imagined only at its final, enormous scale: gigawatt-class satellites in geostationary orbit, launched all at once.

The company’s approach is modular and phased. Before a single satellite is launched, TerraSpark is building commercial radio-frequency wireless power transmission systems for use on Earth, powering remote industrial sites, events, and other locations where running cables is impractical.

This generates revenue, de-risks the technology, and satisfies regulators, all while building towards the orbital version. In the company’s own framing, it is proving the system on the ground before asking anyone to trust it in space.

The three-phase roadmap is concrete. In 2026, the company plans to demonstrate wireless power transmission over controlled distances on Earth, validating alignment accuracy, energy density, and atmospheric tolerance. 

In 2027 it will launch an orbital technology demonstrator and by 2028 aims to beam solar energy from a satellite prototype to a ground receiver, the first space-to-Earth power transmission milestone. Full commercial deployment, with a constellation capable of delivering continuous, weather-independent energy worldwide, is targeted for 2030 and beyond.

In the near term, the company has flagged a wireless power supply for a live event as its first pilot application.

TerraSpark was founded in 2025 by Jasper Deprez, a serial entrepreneur who previously built Tradler into a global HRTech platform, alongside Vijendran and Matthias Laug, who serves as COO. Deprez is CEO.

The venture is based in Luxembourg, which has become a notable European hub for space-economy startups partly because of the country’s favourable regulatory framework for commercial space activities. Vijendran’s background is in physics, he holds a PhD from Cambridge, and his years running ESA’s Solaris programme give him a detailed understanding of both the technical barriers and the regulatory path that space-based solar power faces.

TerraSpark’s European positioning and its deliberate start-on-Earth strategy distinguishes it from both: it is not betting on an orbital demonstration first, and it is building towards infrastructure rather than defence or data-centre applications. Whether that market exists at commercial scale before 2030 remains the central open question.

Serials have become the backbone of the streaming era, especially on Netflix. Serialized television is when a show’s plot unfolds in sequential order over the course of a season. It’s long-form storytelling that typically works best with dramas—Stranger Things, The Crown, etc. Watching the episodes in release order matters. Often, these shows are binged because the complex character arcs and cliffhangers encourage streaming multiple episodes at once.

Serial shows can feel like homework, especially when you fall behind on an episode and need to catch up. That always happens to me, and it leads to anxiety I didn’t want. Thankfully, Netflix offers shows where viewers can jump at any time and not feel lost. These episodic series are perfect for jumping around and picking the episodes you want to watch. One of the most famous comedies ever fits the criteria of an episodic sitcom. Anthology shows, including a Netflix sci-fi classic, are also ideal for watching episodes out of order.

Black Mirror

Welcome to your worst nightmare

Black Mirror wants to scare you. Charlie Brooker’s sci-fi anthology series has been warning humanity about the dangers of technology since 2011. It seems like ages ago that Rory Kinnear had sexual intercourse with a pig in the first episode. Apologies for the spoiler, but the media’s role in the spread of misinformation has never been more relevant.

Black Mirror features self-contained episodes with a beginning, middle, and an end. There has only been one direct sequel: USS Callister: Into Infinity, a season 7 episode that continues the events of season 4’s USS Callister. Otherwise, feel free to jump around and check out the best episodes of each season. Since most episodes feature bleak endings, I’ll leave you with one that ends on an upbeat note: San Junipero.

Seinfeld

Greatest comedy ever?

Comedies are the perfect vehicle for episodic storytelling. While having an overarching plot throughout a season helps attract viewers, many comedy fans are just looking for a few laughs. Write a self-contained story with numerous jokes over 20 to 30 minutes, and you’re ready to go. Seinfeld, aka the show about nothing, is the ideal escape from serialized dramas.

Seinfeld stars Jerry Seinfeld as a fictionalized version of himself as he navigates the comedic scene in New York City. The show revolves around Jerry’s interactions with his friends George (Jason Alexander), Elaine (Julia Louis-Dreyfus), and Kramer (Michael Richards). The gang faces a problem, hilarity ensues, and the episode ends. That’s really all you need to know. Enjoy the laughs.

Guillermo del Toro’s Cabinet of Curiosities

The genre maestro curates new horror stories

There’s a reason why Guillermo del Toro is considered the “King of the Monsters.” The genre expert is as elite as it comes when dealing with mythology and creating new worlds. The Oscar winner relied on his horror expertise in the anthology series Guillermo del Toro’s Cabinet of Curiosities.

I hate referring to episodes of television as “mini-movies.” However, that’s how I would describe the eight episodes of Cabinet of Curiosities. Each director puts their own signature style on a story and brings audiences into their terrifying creation. Del Toro wrote two of the episodes, including one about a demon being summoned. Some are scarier than others, but horror fans will feel right at home with this series. ​​​​​​​

Beat Bobby Flay

Bobby brings the heat

As I’ve gotten older, the Food Network has become one of my favorite channels. I mean, who doesn’t love food? I love eating my (average) home-cooked meal while watching contestants duke it out in the kitchen on my favorite show, Beat Bobby Flay. The competition breaks down into two rounds. In the first round, two chefs have 20 minutes to construct a meal using a secret ingredient. The winner advances to the main event, where they face off against Bobby Flay.

The challenger gets to pick the dish for the final round, so Bobby has a disadvantage. However, Bobby is an award-winning chef with a few tricks up his sleeves. He can handle making a version of your grandmother’s lasagna. With episodes available on Netflix, be prepared to learn why Bobby always throws chiles into his dishes.​​​​​​​

S.W.A.T.

Broadcast TV still knows how to make entertaining programs

The procedural is a genre best produced on broadcast television. Name a cop, doctor, or law drama—chances are it’s a procedural on broadcast TV. While the way we watch television has changed, people still love these types of shows on CBS, NBC, Fox, and ABC. Law & Order, NCIS, and Criminal Minds are procedurals that gained a bigger following thanks to streaming.

S.W.A.T. is cut from the same cloth as Chicago P.D. and CSI. Sergeant Daniel “Hondo” Harrelson (Shemar Moore) is tasked with leading a new S.W.A.T. unit in the LAPD. This action-packed show utilizes a “case of the week” formula in which the team must solve a dangerous situation, such as active shooters and hostage situations. You’re in and out in 44 minutes. What’s better than that?​​​​​​​


Netflix has more content coming your way

After you’re done watching these shows, stay on Netflix for more top-notch content. Netflix has an entire section dedicated to thrillers, and this week, The Guilty and El Camino are two of the section’s best. Keep an eye out for new movies, like Alan Ritchson’s War Machine, which is currently in the streamer’s top 10.
