SpaceX Rideshare Alternatives for 2027 and 2028: Small Launchers, European Rideshares and Brokers Compared

If you are looking for an alternative to SpaceX rideshare for a launch in 2027 or 2028, there are four kinds of options: integrator missions that buy whole rockets and resell the space (Exolaunch Exo-1 and Exo-2, SEOPS Waymaker), dedicated or shared small launchers (Rocket Lab Electron, Isar Aerospace Spectrum, Firefly Alpha), European and Indian rideshare dispensers on medium launchers (Vega C with SSMS, PSLV through NSIL) and orbital transfer vehicles that take you from a standard drop-off to your own orbit (D-Orbit and others). As of 3 November 2026, the SpaceX booking system lists two flights with open capacity, both to sun-synchronous orbit in June and October 2027, at $7,500 per kg. Everything else on this list is quoted on request. This guide compares the routes by orbit, mass, earliest date and what each provider publishes itself.

Why look beyond SpaceX rideshare?

SpaceX rideshare is the reference point for small satellite launch because it is the only program that publishes its price per kilogram, its plate sizes and its open flights. For many missions it is the right choice. There are still good reasons to collect alternatives early:

Fixed orbits: the open SpaceX flights go to SSO at 500 to 600 km. A satellite that needs another inclination or altitude has to adapt or find another ride.
Few listed dates: the booking system shows two flights. If your satellite misses both, the next option depends on flights not listed yet.
Funding rules: European co-funding can require a European launch; see our guide to the ESA Flight Ticket Initiative.
Fallback: SpaceX lets you apply money paid to a future mission, subject to a rebooking fee of 5 to 10 percent according to its rideshare page, but that only helps if a suitable future mission exists.

For the general trade-offs, read our explainer on rideshare vs dedicated launch. This article compares the concrete alternatives.

The SpaceX baseline in November 2026

To compare alternatives you need the reference numbers. From SpaceX's own sources:

Price: the price configuration of the booking system lists $7,000 per kg for the 2026 payment year and $7,500 per kg for 2027. Our article on the SpaceX rideshare price per kg by year explains the payment year rule.
Minimum spend: 50 kg on a quarter plate, 100 kg on a half plate, 200 kg on a full plate and 300 kg on an XL plate. The maximum mass is 300 kg on a quarter plate, 452 kg on a half plate and 831 kg on a full or XL plate.
Open flights: the flight list of the booking system, retrieved on 3 November 2026, shows two flights, no earlier than 1 June 2027 and no earlier than 1 October 2027, both to SSO with apogee and perigee of 500 to 600 km. No other flight is listed at the moment. That does not mean none will be added; it means none can be booked online today.
Cadence: SpaceX's rideshare page states SSO missions approximately every four months and "frequent launches to mid-inclination". The current flight list contains no mid-inclination flight; our comparison of Transporter and Bandwagon covers that gap.
Delivery: payloads arrive at the launch site around 30 days before launch.

Every alternative below should be compared against these points: price per kg, orbit, earliest realistic date and what happens if you are late.

Alternatives at a glance

Capacity, published dates and pricing, as stated by each provider on 3 November 2026:

Exolaunch Exo-1 and Exo-2 (integrator, Falcon 9): two dedicated Falcon 9 missions bought by Exolaunch, no earlier than late 2027 and 2028. Satellites from 20 kg to 1,400 kg and CubeSats. No public price or orbit.
SEOPS Waymaker (integrator): Waymaker-1 to a mid-inclination orbit at about 500 km, target window early 2028; Waymaker-2 to SSO at about 500 km, late 2028. Half, Full and XL volume classes with 100, 200 and 300 kg included, plus Cake Topper. No public price.
Rocket Lab Electron (small launcher): 300 kg to LEO, dedicated or rideshare, 99 launches to date, three dedicated launch pads. No public price.
Isar Aerospace Spectrum (European small launcher): 1,000 kg to LEO and 700 kg to SSO, reached orbit on its second flight on 5 September 2026 from Andøya, Norway. No public price.
Firefly Alpha (small launcher): 1,030 kg to a 300 km LEO and 630 kg to a 500 km SSO, dedicated and multi-payload missions. No public price.
Vega C with SSMS (European medium launcher): up to 2,300 kg to LEO, with the SSMS dispenser for clusters of small satellites. No public price.
PSLV through NSIL (Indian medium launcher): 1,750 kg to a 600 km sun-synchronous polar orbit, ride sharing and dedicated missions. Under review after the PSLV-C62 anomaly in January 2026. No public price.
Orbital transfer vehicles: D-Orbit and others carry satellites from a rideshare drop-off orbit to a custom orbit. Priced per mission.

Only SpaceX publishes a price per kilogram. For every other route the only way to compare cost is to request offers on the same basis.

Integrator missions: Falcon 9 capacity sold by someone else

The closest alternative to a SpaceX rideshare plate is often still a Falcon 9, but booked through an integrator who has bought the whole rocket. These missions add dates and, in some cases, orbits that the public SpaceX list does not show.

Exolaunch Exo-1 and Exo-2

On 26 May 2026, Exolaunch announced a contract with SpaceX for two Falcon 9 launches, Exo-1 and Exo-2, "scheduled to launch no earlier than late 2027 and 2028, respectively". According to Exolaunch, the missions are meant for "constellation deployments, governmental programs, and large-scale launch campaigns" and will use its EXOtube payload stacks, "suited for satellites from 20kg to 1,400kg and beyond", plus EXOpod deployers for CubeSats. The release names no target orbits or prices, so ask for both. Exolaunch also lists relationships with launch providers including Rocket Lab, Isar Aerospace, Firefly, Arianespace and NSIL, which makes it one contact for several vehicles. See Exolaunch on Carrier Space.

SEOPS Waymaker

SEOPS sells its Waymaker program as "confirmed LEO rideshare capacity" with defined interface classes. Its page lists two upcoming missions:

Waymaker-1: mid-inclination orbit, nominal insertion altitude about 500 km, target launch window early 2028, single-drop deployment.
Waymaker-2: sun-synchronous orbit, about 500 km, target launch window late 2028.

Customers choose a Half Volume class (100 kg included), Full Volume (200 kg included), XL Volume (300 kg included) or a Cake Topper position; CubeSat capacity is marked as limited and under evaluation. SEOPS states that "capacity is reserved only upon executed Launch Services Agreement", so a reservation form alone does not hold a slot. Waymaker-1 is relevant for anyone who needs mid-inclination, because the SpaceX booking system lists no such flight today. In September 2026, Isar Aerospace announced that five Spectrum launches between 2028 and 2030 would expand Waymaker with European rideshare launches. See SEOPS on Carrier Space.

Our comparison of launch brokers and rideshare integrators explains what these companies add on top of the launch itself.

Small launchers: your orbit, your date

A small launcher is the most direct alternative when the orbit or date of a rideshare does not fit. You pay more per kilogram, but the rocket goes where your mission needs it. Our detailed small launcher comparison covers the vehicles in more depth; here is what matters for a 2027 or 2028 booking.

Rocket Lab Electron

Rocket Lab lists Electron with 300 kg to LEO, 99 launches to date and three dedicated launch pads, and describes it as "dedicated access to space for small satellites". Its Kick Stage serves missions "whether flying as dedicated or rideshare" and can deploy payloads into multiple planes. The 99th Electron flight lifted off on 3 November 2026 (New Zealand time) from Launch Complex 1 and placed a radar satellite for iQPS into a 575 km orbit; Rocket Lab called it its 20th mission of 2026 and said iQPS has eight more dedicated Electron launches booked to complete its constellation by 2030. Ask Rocket Lab directly for open dates in your window. See Rocket Lab on Carrier Space.

Isar Aerospace Spectrum

Spectrum carries 1,000 kg to LEO and 700 kg to SSO according to Isar Aerospace. On 5 September 2026 it reached orbit on its second flight from Andøya, Norway, making Isar "the first commercial space company from Europe to successfully deliver satellites into orbit". Isar is also building a launch complex in Nova Scotia, Canada, for mid- to high-inclination orbits. Two press releases from September 2026 matter for availability: the agreement with SEOPS for five launches between 2028 and 2030, which according to Isar "brings the 2028 manifest of Isar Aerospace close to full", and a contract with Astroscale Japan for ADRAS-J2, targeted for 2027 to 2028. If you want Spectrum in 2028, ask early, and ask SEOPS too, since part of that capacity will be sold through Waymaker. Our Spectrum guide covers booking. See Isar Aerospace on Carrier Space.

Firefly Alpha

Firefly lists Alpha with 1,030 kg to a 300 km LEO and 630 kg to a 500 km SSO and a fairing 2.2 m in diameter. Firefly says Alpha supports "dedicated satellites, multi-payload deployments, and hypersonic testing" and can launch from its east and west coast US sites and from Esrange Space Center in Sweden. See Firefly Aerospace on Carrier Space.

Other European newcomers

Isar Aerospace, Rocket Factory Augsburg and PLD Space hold contracts under ESA's European Launcher Challenge, which ties funding to orbital and upgrade milestones. Our explainer on the European Launcher Challenge lists each vehicle, launch site and status. For a 2028 mission they are worth including in a request, with a fallback in case a first flight slips.

Rideshare dispensers on medium launchers

Vega C with SSMS

Avio lists Vega C with up to 2,300 kg to LEO and says the rocket "takes full advantage of the capabilities of the various SSMS (Small Spacecraft Mission Service) payload adapters". Its AVUM+ upper stage can release multiple satellites into different orbits on one mission. ESA introduced the SSMS dispenser in 2020 as a rideshare service for light satellites; according to ESA, it "can accommodate any combination of 1 kg CubeSats up to 500 kg minisatellites", either on a dedicated rideshare or alongside a larger main satellite. Avio does not publish SSMS prices or a list of open rideshare flights, so a specific request is needed. See our Vega C guide and Avio on Carrier Space.

PSLV through NSIL

ISRO lists PSLV with 1,750 kg to a 600 km sun-synchronous polar orbit and says NSIL, its commercial arm, offers launch solutions for both ride sharing and dedicated missions, with in-house separation systems. The PSLV-C62 mission, a dedicated NSIL mission with 15 co-passenger satellites, "encountered an anomaly during end of the PS3 stage" in January 2026. In its latest update on 25 February 2026, ISRO said a national-level expert committee was reviewing the cause. Before you plan on PSLV for 2027, ask NSIL for the return to flight schedule. ISRO's SSLV is designed for 500 kg to a 500 km LEO. Export rules also matter; see our guide to Indian launch options.

Orbital transfer vehicles: rideshare price, custom orbit

If the main problem with a rideshare is the orbit and not the date, an orbital transfer vehicle can close the gap. D-Orbit describes three services: rideshare on "third-party compatible launchers" with its own dispensers into a standard parking orbit, Precision Deployment with its ION Satellite Carrier for custom orbits, and phasing for constellations "to phase a batch of spacecraft quickly and safely". D-Orbit does not publish prices. Our space tug comparison lists the other vehicles, and our article on constellation deployment with OTVs explains the manoeuvres. See D-Orbit on Carrier Space.

Worked example: an 80 kg satellite that may miss October 2027

Take an operator with an 80 kg Earth observation satellite on an 8 inch interface. It needs SSO at about 550 km and the team expects it to be ready to ship in summer 2027, with a real risk of slipping by a few months. The figures below are our own calculation from SpaceX's public price configuration and the providers' published data.

Plan A, SpaceX rideshare: the October 2027 SSO flight fits the orbit. 80 kg times $7,500 per kg is $600,000 for the launch at 2027 prices; the 50 kg quarter plate minimum does not apply. If the satellite slips past October 2027, there is no later flight in the booking system today.
Plan B, integrator Falcon 9: Exolaunch Exo-1 (no earlier than late 2027) and Exo-2 (2028). Ask for the target orbits and whether a slot can be held for a satellite that is not yet fully qualified.
Plan C, Waymaker-2: SSO at about 500 km in late 2028, Half Volume class with 100 kg included. Later, but a named mission to the right type of orbit.
Plan D, small launcher: on Electron an 80 kg satellite uses a little over a quarter of the published 300 kg capacity, so it could fly with other payloads or as the main customer. On Spectrum, Isar describes its 2028 manifest as close to full, so ask about 2028 and 2029.
Plan E, European funding: if the satellite qualifies for European co-funding, Vega C SSMS and Spectrum are the European routes that have reached orbit.

The practical step, in our view, is to request offers for plans A to D at the same time, with the same data: mass with margin, interface, target orbit with tolerances, earliest ready date and latest acceptable launch date.

How to compare the offers

Orbit tolerance: ask every provider for the insertion orbit and tolerances in the same format.
Firm date or target window: "no earlier than" is not a contracted launch period. Ask what the contract says.
What is included: separation system, integration, testing, transport, fueling. On SpaceX, an 8 inch separation system costs $370,500 at 2027 prices.
Delay terms: what happens if you are late, and if the rocket is late; see our guide on launch delays.
When capacity is held: SEOPS only reserves capacity once a Launch Services Agreement is signed. Ask each provider when your slot is secure.

FAQ

What are the main alternatives to SpaceX rideshare?

Integrator missions (Exolaunch Exo-1 and Exo-2, SEOPS Waymaker), small launchers (Electron, Spectrum, Alpha), dispensers on Vega C and PSLV, and orbital transfer vehicles such as D-Orbit's ION.

Which SpaceX rideshare flights can be booked for 2027?

On 3 November 2026 the booking system listed two flights, no earlier than June and October 2027, both to SSO at 500 to 600 km. No others were listed.

Is there a European alternative to SpaceX rideshare?

Yes. Vega C carries clusters of small satellites on the SSMS dispenser, and Spectrum reached orbit from Norway in September 2026. Isar says SEOPS will sell rideshare launches on Spectrum through Waymaker from 2028.

Do other providers publish prices like SpaceX?

No. All other providers in this guide quote per mission. SpaceX publishes $7,500 per kg for 2027.

Which alternative works for a mid-inclination orbit?

SpaceX lists no mid-inclination flight today. SEOPS Waymaker-1 targets one at about 500 km in early 2028; small launchers and transfer vehicles can reach other inclinations.

How early should I ask for alternatives?

As early as you ask SpaceX, which starts its formal process eight months before launch. Isar describes its 2028 manifest as close to full.

Find a ride with space left

When few flights are listed, the chance of finding a suitable slot rises with the number of providers you ask. On Carrier Space you can compare launch vehicles, missions and providers with data checked weekly, and then send one request to up to five providers and brokers you pick. Carrier Space checks the request, forwards it anonymously and returns indicative offers in one comparable view; the provider learns who you are only when you choose its offer. With your consent, a request can also be published anonymously on the rideshare marketplace so others can join a flight. It is free for customers.
