Inside the first private mission to Mars

Inside the first private mission to Mars

Dear readers,

Apologies for the delayed delivery. This newsletter’s launch was scrubbed due to hydrogen leaks detected in our CMS (Content Management System). After inspecting and replacing a valve, the countdown was resumed. 

Welcome to Quartz’s newsletter on the economic possibilities of the extraterrestrial sphere. Please forward widely, and let me know what you think. This week: The business of deep space, Russia says it’s done with the ISS (again), and Eutelsat and OneWeb plot a merger.

Mars: So red, so far, so lucrative?

The news that two nascent space companies are planning the first private mission to the planet is exciting, but the question is whether this is a PR stunt, a technology development program, or a business worth investing in. I caught up with Relativity Space and Impulse Space CEOs Tim Ellis and Tom Mueller to get the backstory

This was Relativity’s idea, a way to connect with the company’s founding obsession of building the first factory on Mars with 3D printing technology. The company is getting close to flying its first rocket, the Terran 1, next year, but this mission mission to Mars would mark the first flight of the company’s next-generation rocket, the Terran R, in 2024.

That makes it low risk, Ellis says. They have to build Terran R anyway—the company has sold $1.2 billion worth of launches on the vehicle to OneWeb and other customers. So what’s the best payload for a test flight? Flying a customer’s payload can be risky. Flying a wheel of cheese is fun. Launching a car into deep space is an attention-getter. Relativity wants to go one better: Let’s put the first private lander on Mars.

“When Relativity first approached me to do this, [it] kind of caught me by surprise,” Mueller says. He started Impulse to build space tugs in 2021, after leading propulsion at SpaceX since the company’s inception. “[Ellis] gave me an out, he said, ‘we want to go to Mars, we could go into orbit or we could land.’ I just said, well, we gotta land. So I immediately went for the harder part.”

Landing on Mars is famously difficult. Only three nations have done the trick, with NASA’s Jet Propulsion Laboratory the specialists in this department. Mueller hopes to adapt the entry, descent, and landing approach used by the Mars Insight Lander, which involves using a heat shield to slow down while entering the planet’s atmosphere, parachutes that deploy within it, and finally rockets that fire to bring the whole thing to a soft landing.

That mission cost about $816 million. Ellis says the two companies will be able go to Mars at a cost several times less than that. That’s believable: The mission will be smaller, with “tens of pounds” of scientific payloads arriving on Mars, instead of Insight’s 50 kg (110 lbs). It will cost less to launch than $163 million required for Insight. And the lander itself will rely on a proven design, and not include the cost of the super-sensitive scientific instruments that represented a large chunk of Insight’s cost.

Still, this is a project on the order of hundreds of millions of dollars. The companies hope to recruit a customer who will pay to put scientific instruments onboard the lander, whether that is NASA, another space agency, or a university, which would help defray the cost. At the very least, Ellis says, the lander will collect images of Mars and send them back to Earth.

“We will find someone to put payload even on the very first mission, but it’s not just about a one time mission,” Ellis says. “Once we show that it works successfully and we can do it, this is not ‘a build it and they will come.’ I do think the demand is there. We just need to do it.”

Just getting these vehicles built, tested, and on the pad will be an accomplishment. Then the real fun starts: Mueller notes that problems that might be tolerable on a two-week mission, like a small leak, could ruin a 300-day spaceflight. The precision required to keep antennas and solar panels pointed at the Earth is magnified by the millions of miles the spacecraft must travel. And assuming the vehicle gets there, the soft landing is the hardest part.

The lander’s primary propulsion system will be the same as the one that Impulse’s spacecraft will use to deploy satellites in Earth orbit. Impulse plans to fly one of these on orbit before the Mars launch, and also demonstrate a hover test on Earth next year.

Any discussion of private space exploration will include SpaceX and Elon Musk. Ellis doesn’t think the narrative of ‘Relativity vs. SpaceX on race to Mars’ makes much sense, because he sees both efforts as complementary. Indeed, SpaceX isn’t racing to Mars because it can’t find anyone who will pay for it. Instead, Musk has redesigned Starship, its next-generation rocket, to focus on NASA’s return to the Moon (and to launch Starlink satellites.) Musk’s ultimate vision, of course, is a vehicle large enough to support human visits to Mars. That’s a challenge beyond Relativity and Impulse’s plans.

“We don’t need all the in-orbit refueling missions, like what Starship needs, like they need a bazillion refueling missions before they can even launch something [to Mars],” Ellis says. “This is a little bit more traditional lander style, but we’re taking commercial space and more startup-like, agile approaches to development and bringing that to interplanetary transport.”

Mueller was involved when SpaceX hatched a plan to launch a version of its Dragon spacecraft to Mars in 2016. It ultimately foundered when the design of that vehicle changed to depend on parachutes for landing instead of rockets. The lesson is to keep your advanced projects as close to your main technology program, if you want to do it on the cheap.

“We’re focused on the orbital transfer, cause that’s [an] easy-to-address existing market,” Mueller says. “It was actually great that this came along when it did, cause this would improve our skillset. You have a real motivator, it helps us hire, it just builds morale around here cause it’s a really cool mission.”

From a business point of view, a better analogy than SpaceX is Rocket Lab’s campaign of deep space missions. The company, which builds both rockets and spacecraft, sent a orbiter to the Moon earlier this month, and has plans to do the same at Venus and Mars. It’s clear that low-cost transportation into deep space is a growing market, even if all these companies bread and butter will be putting satellites into low-Earth orbit. But Ellis and Mueller are true believers.

“We finally are at the point where we can start to execute on the original vision that we had, of truly making humanity multi-planetary,” Ellis says. “We need a dozen to hundred companies to have this mission of seeing a million people on Mars happen in our lifetime.”

This week, NASA announced that its plan to recover samples collected by Perseverance will use two new helicopters, thanks to Ingenuity’s successful demo flights. The mission is planned to launch in 2030, with samples returning to Earth in 2033.



Russia to leave ISS (again). The new head of Roscosmos told president Vladimir Putin that 2024 will be the last year Russia participates in the International Space Station. It’s not the first time, and NASA has yet to hear anything official. Sanctions and political tensions have made the space partnership more challenging, but few believe Russia can launch its own orbital habitat. That’s likely why Russian space officials quietly told NASA a few days later that they plan to stay at the station until 2028.

The pair that dares. OneWeb and Eutelsat are plotting a $3.4 billion merger that would unite the former’s broadband internet satellite network with the latter’s high-altitude satellites, a combination that could compete with SpaceX’s Starlink network. It’s a tricky deal, including stakes held by the UK and France that might lead to political complications. “The biggest hurdles most likely are the shareholder vote and the Herculean feat of funding the capital needs resulting from the transaction,” Chris Quilty, the founder of Quilty Analytics, tells Quartz. “If Eutelsat can elucidate a compelling finance plan—whether through government support or existing equity investors—these two should make it to the altar.”

SpaceX breaks its own annual launch record. They’ve launched 32 rockets, one more than in 2021, and it’s only July.

China builds its space station. new module has docked with Tiangong, China’s new habitat in low-Earth orbit. The fate of the huge rocket that launched it, however, has been top of mind: It’s not supposed to hit anyone when it reenters the atmosphere, but experts say China isn’t taking enough precautions.

Moon rock philanthropy. OrbitFab, which is building in-space refueling technology, has a plan to purchase lunar regolith collected by a private company and donate it to Breaking Ground, a trust dedicated to creating new models of managing resources on the Moon. NASA is paying private companies to collect soil on the Moon for scientific purposes, but also to establish the legal precedent for transactions in space. This new project aims to establish precedents for non-commercial ownership and management, and prevent monopolization.
