What Does It Cost to Launch a Small Spacecraft to an Asteroid in 2026?

Ten years ago the launch was the reason asteroid missions belonged to governments. A rocket cost more than a small company could raise. In 2026 that has flipped: a ride to orbit for a 200 kilogram spacecraft costs about as much as a modest house in London. The catch is that almost nobody will sell you a ride beyond orbit. Frontier's third research brief works through what it actually costs, in dollars and in physics, to get a small prospector onto a path to a near-Earth asteroid between now and 2030.

The benchmark: $7,000 per kilogram

Start with the one price everyone can see. SpaceX's Falcon 9 rideshare programme advertises $350,000 for up to 50 kilograms to sun-synchronous orbit, then $7,000 for every kilogram beyond that. A 100 kg spacecraft is $700,000; 200 kg is $1.4 million.

It has not stood still. The programme opened in 2019 at $1 million for 200 kilograms, or $5,000 per kilo. It rose to $5,500, then to $6,500 in March 2023, and now $7,000. The chief executive of asteroid-mining startup Karman+ puts it simply: SpaceX "raises their prices by 10% every year". Budget for 2029 accordingly.

The price buys a standard drop-off and a standard integration process. It does not include the separation system, payload processing, shipping, insurance, or any manoeuvring after release. If you miss your flight, SpaceX credits what you paid to a later one, less a 5 to 10 percent rebooking fee.

And here is the limitation. The published card covers sun-synchronous orbit. Mid-inclination orbit (the Bandwagon flights), geostationary transfer orbit and trans-lunar injection are all available, but only "by inquiry". For a mission that needs to leave Earth entirely, the one price on the internet is the wrong one.

Everyone else: mostly unpublished

Rocket Lab publishes no list price for Electron. Aggregators quote about $7.5 million for roughly 300 kg to low orbit; the company's actual launches averaged about $9.2 million in revenue in the first half of 2026. Its larger Neutron is pencilled at $50 to 55 million and has not yet flown.

Europe's Vega-C costs around €48 million and the smaller Ariane 6 about €100 million per dedicated launch; neither publishes a rideshare rate. India's PSLV is reported at ₹130 to 200 crore, roughly $13 to 21 million, and the small SSLV at about $3 to 3.6 million but only to low orbit. The space tugs that have attracted billions in investment, Impulse Space's Mira and Helios, Exotrail's SpaceVan, Momentus, D-Orbit, publish no commercial prices either. The only public Mira numbers are $28 to 31 million government contracts that bundle the payload in.

So the question becomes: what has anyone actually paid to send something small to deep space?

What AstroForge did

The best data point comes from AstroForge, the California startup trying to mine metallic asteroids. In February 2025 its 120 kg spacecraft Odin flew as a secondary passenger on the Falcon 9 that launched Intuitive Machines' IM-2 lunar lander. The whole mission was reported at under $7 million, and the company says it spent $3.5 million on the spacecraft itself. That bounds the launch share at roughly $3.5 million or less for a ride to the edge of Earth's gravity.

Odin was lost within days, probably to a solar array that did not deploy, and the company's own debrief is unusually candid about ground-station failures and competition for deep-space dish time. But the launch worked, and the successor, a 200 kg electric-propulsion spacecraft, is booked on IM-3 for a mission priced at under $10.5 million including launch. IM-3 has slipped from early 2026 to late 2026 or early 2027. AstroForge's chief executive described the stakes of the first ride bluntly: "we're either on IM-2 or we're not a company."

The lesson is double-edged. Riding a lunar lander's rocket is the cheapest proven route to deep space. It also ties your schedule, and possibly your company, to someone else's.

The $10 million dedicated option

If you want your own rocket, the floor is Rocket Lab. In 2020 NASA paid $9.95 million, fixed price, to send the 25 kg CAPSTONE cubesat to the Moon on an Electron topped with a Photon kick stage. It arrived in 2022. Rocket Lab's founder Peter Beck has framed the offer as "$10 to 20 million" for interplanetary science, against the $50 to 100 million that such missions used to cost. His own Venus probe uses the same Photon stage with a lunar flyby to reach escape.

The physics is kinder than the price list

Here is the part that makes a small asteroid mission possible at all. Leaving Earth is not as expensive, in velocity terms, as it sounds, provided you start from the right orbit.

A spacecraft dropped into geostationary transfer orbit, the elongated path that communications satellites use, needs only 770 metres per second of extra speed at its lowest point to escape Earth entirely. NASA's Launch Services Program has worked out that a cheap solid-fuel kick stage giving 1,800 metres per second could send four 35 kg spacecraft from a single GTO rideshare to four different asteroids, with "almost daily launch opportunities" to one target or another.

For a rendezvous rather than a flyby you need more, but not a lot more. Frontier's first brief found the most accessible targets need 3.5 to 6 km/s for a full round trip starting from low orbit, and most of that is the departure burn a GTO drop-off has already paid for. The brief assembles a one-way budget of roughly 1.5 to 3.5 km/s after drop-off for a trip to a low-delta-v asteroid.

With an electric thruster like the Busek BIT-3, which runs at up to 2,300 seconds of specific impulse on 65 to 80 watts, 3.5 km/s costs about 16 percent of the spacecraft's mass in xenon: 16 kg on a 100 kg craft, 31 kg on 200. AstroForge's DeepSpace-2 carries 60 kg of xenon on a 200 kg bus, enough for 5 to 7.5 km/s. Chemical rockets would eat more than half the spacecraft for the same job, which is why every private asteroid mission after Odin has gone electric.

The cost table

Putting it together for a 100 to 200 kg prospector, launch and transfer only, spacecraft not included:

The planning figure for the first three routes is about $3 million low, $5 to 8 million likely, $15 to 20 million high. That matches what AstroForge is spending and leaves room, inside the $10 to 20 million mission envelope from Frontier's first brief, for the spacecraft, the ground stations and the people.

When to book

Transporter flights go roughly every two to three months; Transporter-17 carried 81 payloads in July 2026 and Transporter-18 and Bandwagon-5 are both due in October. Deep-space slots are rarer and move with their primary. AstroForge had to deliver Odin 35 days before launch; IM-3 has slipped about a year; Karman+'s first launch has moved from 2026 to 2027 to mid-2028. Nobody publishes a formal lead time. Frontier's working rule is to contract 18 to 24 months ahead and to hold a GTO rideshare option as a fallback to any lunar secondary slot, so that one partner's delay cannot become our cancellation.

The honest conclusion

Launch is no longer the thing that stops a small team reaching an asteroid. For a few million dollars, a 200 kg spacecraft can be dropped at the edge of Earth's gravity, and for a few tens of kilograms of xenon it can go the rest of the way. What stops small teams now is the same thing that stopped Odin: keeping the spacecraft alive and talking once it gets there. The money saved on the rocket should go into the ground stations.
