**Charles Sirois wants to protect our satellites against Russia and China**

**By Sylvain Larocque**

**April 22, 2026**

*NorthStar Sky & Earth is banking on the current enthusiasm for space and the military to appeal to Wall Street*

**A company headed by entrepreneur Charles Sirois wants to protect thousands of Western satellites from threats coming from Russia and China.**

Montreal-based NorthStar Ciel & Terre has just filed its application to go public on the New York Stock Exchange. It hopes to raise US$120 million (CA$164 million) from American and Canadian investors.

**The "endangered" space**

In its prospectus released last week, NorthStar argues that space is "in danger" due to "increasingly frequent active threats".

The company notes that in February, European officials revealed that two Russian spacecraft intercepted communications from at least a dozen important satellites, jeopardizing the sensitive information they transmit.

Last year, Russian hackers took control of a television satellite and broadcast propaganda images in Ukraine.

For its part, China is training to conduct satellite battles, the United States Space Force indicated last year.

**Debris and other lost items**

NorthStar claims its technology can detect "stray objects" in space 52 times faster than some ground-based systems. Space debris can cause serious damage.

"If your satellite is damaged to the point where you can no longer control it, it can become a catastrophe," Hugues Gilbert, a retired Canadian Space Agency employee and researcher at Laval University, told the *Journal .*

The specialist considers NorthStar's platform promising, but points out that several companies are interested in this market, including giants like Airbus and Lockheed Martin.

From 2018 to 2023, Quebec invested nearly $32 million in NorthStar, representing approximately 20% of the funds raised by the company to date. Despite this investment, the company does not name the Quebec government in its financial presentation, simply referring to it as a "Canadian provincial investor."

**In Quebec to stay?**

NorthStar has 74 employees, including about 40 in Quebec and 20 in Luxembourg. The company aims to double its workforce in the medium term.

In 2021, NorthStar CEO Stewart Bain did not rule out a relocation of the company's headquarters.

"I am loyal to Quebec, but [...] we have to do what is best" for NorthStar, he told *La Presse* .

However, the company told the *Journal* on Tuesday that it "intends to maintain its global headquarters in Montreal and to continue expanding its Quebec-based workforce to support central operations."

**Canadian satellite startup NorthStar on track to hit US$300-million valuation after SPAC merger**

**By Yvonne Lau**

**April 21, 2026**

*The company says its missions 'directly' align with Ottawa's defence priorities to protect critical assets in space*

Montreal-based satellite startup NorthStar Earth & Space Inc. says it intends to go public on the New York Stock Exchange by merging with special acquisition purpose company (SPAC) Viking Acquisition Corp. I as investor interest in the space sector grows.

The transaction, expected to close in the third quarter, will boost NorthStar's valuation to US$300 million, with the company set to receive US$30 million from New York private-equity firm Cartesian Capital Group LLC and other unnamed institutional investors from Canada and the United States.

NorthStar, which provides data and other services from its platform of space-based sensors, plans to use the money to pay for engineering costs and launch expenses, which include placing and integrating sensors on satellites.

"At this critical juncture, becoming a public company provides NorthStar with unprecedented access to capital to scale our operations," NorthStar founder and chief executive Stewart Bain said in a statement on Friday.

Founded in 2015, NorthStar has raised US$100 million to date from public and private investors. The startup received early support from the federal and Quebec governments, which invested $13 million each in 2018 to help it build a satellite constellation for earth and space monitoring.

NorthStar has secured contracts with Canadian, U.S. and European governments, including contracts with national space agencies, as well as a commercial contract with the United Arab Emirates' space tech company Space42 PLC.

Last month, Ottawa said $900 million will be directed to innovation under Canada's Defence Industrial Strategy as part of its commitment to grow investments in defence to $82 billion over five years. A NorthStar spokesperson said the company's core mission "directly" aligns with Ottawa's defence priorities to "protect critical assets in space and serve as a front line of defence."

Investor interest in the dual-use space has surged as governments boost spending on space-based security, surveillance and communications technology.

Investors this year poured a record US$36 billion into space companies in the first quarter compared to US$6.7 billion in the same period a year ago, according to venture-capital firm Space Capital LP.

An initial public offering by Elon Musk's Space Exploration Technologies Corp., which is set to come later this year and could be the biggest IPO ever at US$75 billion, is also likely to grow interest in the sector.

A December 2025 report by the Royal Bank of Canada said the global space economy is on track to triple in value to US$1.8 trillion over the next decade, while the opportunities in Canada could amount to more than $21 billion if it can generate $12 billion in new capital for homegrown space ventures during the same timeframe.

**NorthStar to go public via SPAC to expand space-based SSA network**

**by Jason Rainbow**

**April 17, 2026**

NorthStar Earth and Space plans to raise funds to expand the space-based sensor network behind its space situational awareness (SSA) business by merging with Viking Acquisition Corp. I, a publicly listed shell company.

The Canadian SSA provider announced plans April 17 to merge with the special purpose acquisition company, or SPAC, which had about $230 million in trust Dec. 31 shortly after listing on the New York Stock Exchange.

How much of that cash ultimately reaches NorthStar will depend on shareholder redemptions ahead of the merger vote, although the deal is structured to deliver at least $30 million before any additional funds remaining in trust.

Viking is sponsored by KingsRock Advisors, a New York-based financial advisory firm. Viking CEO N. Håkan Wohlin, who also founded KingsRock, previously served as Deutsche Bank's global head of debt origination, capital markets and treasury solutions.

The merger includes a $30 million private investment in public equity (PIPE) add-on, anchored by Cartesian Capital Group, a U.S.-based private equity firm that led NorthStar's Series C funding round in 2023.

NorthStar says it has raised about $100 million to date, including backing from the governments of Quebec and Luxembourg.

The transaction, slated to close before the end of September following shareholder and regulatory approvals, gives NorthStar a pre-money valuation of $300 million.

"At this critical juncture, becoming a public company provides NorthStar with unprecedented access to capital to scale our operations," NorthStar founder and CEO Stewart Bain said in a statement.

"The transaction positions NorthStar to keep pace with the challenges presented by the increased frequency of new launches and deliver greater value to stakeholders across the space industry."

**Rocky road to space**

NorthStar announced in 2020 that it had picked Thales Alenia Space to build an initial batch of satellites for tracking other spacecraft and debris in orbit.

The company pivoted two years later in a deal with space-as-a-service operator Spire for smaller cubesats, targeting a ride to low Earth orbit (LEO) in 2023 with Virgin Orbit, only to have those plans upended by the horizontal air-launcher's bankruptcy earlier that year.

Rocket Lab later successfully deployed four 16U satellites for NorthStar in January 2024, following delays stemming from an Electron launch failure.

The satellites were equipped with sensors designed to enable them to track objects as small as five centimeters across LEO and 40 centimeters in geostationary orbit.

However, one of those satellites was ultimately lost in space and the other three failed to produce contract-compliant images, NorthStar alleged in legal action against Spire.

NorthStar has sought damages for alleged breach of contract, willful misconduct and fraudulent misrepresentation, claims that Spire denies in full.

An arbitral tribunal held an evidentiary hearing on the dispute in January 2026.

![](image_002.jpg)

Spire, which at one point had a contract covering options for 33 satellites for NorthStar, did not respond to a request for comment.

NorthStar's investor presentation on the SPAC merger refers to having four of a planned 96 satellites in orbit.

"NorthStar can confirm that it has four operational satellites in orbit, including satellites launched by Spire," a NorthStar spokesperson said in response to SpaceNews questions.

The company declined to comment on the apparent addition of a non-Spire spacecraft, and whether it is connected to the loss of one of its satellites in orbit.

"We have no further comment on ongoing legal proceedings," the spokesperson continued.

"This morning's news regarding the proposed merger with Viking, demonstrates the company's momentum and points to the future. We believe this transaction will position NorthStar to address the urgent need for advanced Space Situation Awareness globally and service the rapidly growing space economy.

"Safeguarding our orbital environments and advancing sustainability in space has never been more important, and we expect NorthStar will play a critical role in advancing this mission."

In 2023, NorthStar said five Earth observation satellites from Japan's Axelspace are helping it keep tabs on orbits.

**Expanding SSA capabilities**

NorthStar said in the presentation that it currently draws on 80 million observations a day to track activity and detect threats in orbit, supported by third-party ground- and space-based data.

The company pointed to growing demand from government and commercial customers, estimating more than $30 million in revenue in 2026.

![](image_003.jpg)

The presentation also outlined a phased deployment of "bespoke sensors," with more than five planned for the next phase to support a "120-minute revisit rate of all resident space objects."

A final phase in the roadmap, which does not provide details such as a timeframe, envisions more than 90 sensors supporting a 20-minute revisit rate.

The proposed merger comes amid signs that SPACs are returning to the space sector, after the last cycle around five years ago left many investors wary of aggressive long-range projections.

Meanwhile, the industry is seeing an uptick in traditional, more heavily scrutinized IPOs as plans for a blockbuster SpaceX listing this summer add another tailwind for investor interest in the industry.
