Specs as of September 10, 2026 — verify official pages before citing.
There is no single “race to Mars” with one finish line. Cargo, crew, sample return, and settlement are different problems — often on different architectures: Mars-capable transport, a lunar proving-ground path, or robotic science.
This dated comparison restates what the main players say publicly, what the vehicles are designed to do, and where bottlenecks sit. Numbers come from official pages or clearly labeled wires. They are not rankings or predictions.

Three lanes, not one scoreboard
| Lane | What it means | Who is mainly here (v1) |
|---|---|---|
| Mars-capable architecture | Ops concepts aimed at serious mass and eventually people on Mars | SpaceX Starship |
| Lunar path | Heavy lift and landers framed as Moon work that could support later deep-space ops | Blue Origin New Glenn + Blue Moon; NASA SLS / Artemis |
| Robotic Mars science | Orbiters, landers, rovers, sample return — science first | NASA fleet; CNSA Tianwen-3; ESA Rosalind Franklin / ExoMars |
Blue Origin’s multiplanetary language and NASA’s Moon-to-Mars framing sit between lanes — stated intent plus hardware path, not a Mars landing date.
Comparison at a glance
| Player | Flagship / program | Stated goal | Public capability | Reuse | Timeline | Bottleneck |
|---|---|---|---|---|---|---|
| SpaceX | Starship / Super Heavy | Cargo to Martian surface; settlement architecture | >100 t reusable to orbit; tanker / LEO refill | Fully reusable design goal | NET 2028; $100M/t; ~26-month windows | Orbital refuel + flight rate |
| Blue Origin | New Glenn + Blue Moon | Heavy lift + lunar lander path; ESCAPADE science ride | 45 t LEO; >13 t GTO; Mk1 3 t; Mk2 4-crew / 30 t lunar | 1st stage ≥25 flights | ESCAPADE; lunar milestones | No public Mars vehicle timeline |
| NASA | SLS / Artemis + Mars fleet | Moon proving ground; robotic Mars science | Block 1 >27 t; 1B ~38 t; Block 2 up to 46 t | Expendable | Artemis cadence + assets | Budget, cadence, crew systems |
| CNSA | Tianwen-3 | Mars sample return | Mission-defined; samples ≥500 g | Not framed as reusable here | Launch ~2028; samples ~2031 | Complex robotics on synodic clock |
| ESA | ExoMars / Rosalind Franklin | Robotic surface science | Rover mission | N/A | Target 2028 | Schedule heritage; launch partnership |
SpaceX — Starship as Mars architecture
SpaceX is the only major player whose current public vehicle pages put Martian surface cargo, pricing, and settlement language in one architecture: Starship, Super Heavy, and tanker refill in LEO before departure.
Public specs (verify live pages before citing):
- Designed for more than 100 metric tonnes to orbit in a fully reusable configuration (Starship).
- Mars materials emphasize orbital refueling—tanker flights topping up a Mars-bound ship in LEO—and the same ~26-month transfer-window cadence covered in our launch-windows explainer.
- Cargo flights to the Martian surface for research, development, and exploratory missions are listed no earlier than 2028, at $100 million per metric ton (Mission: Mars).
Treat NET 2028 as a commercial earliest-date floor, not a guaranteed launch or landing year. Bottleneck: demonstrated propellant transfer and enough successful flights inside a short departure season.
Blue Origin — New Glenn lift + Blue Moon lunar path
Blue Origin’s near-term public hardware story is heavy lift and lunar landing, not a dated Mars cargo offer. Lift mass and lander experience still matter for a Mars future—they are not the same as a published Martian-surface schedule.
- First-stage design reuse: ≥25 flights
- Payload: >13 t to GTO; 45 t to LEO
- 7× BE-4; height >320 ft; 7 m fairing
Source: New Glenn.
Blue Moon (lunar):
- Mark 1: up to 3 t cargo
- Mark 2: 4-crew capable; cargo variant up to 30 t to the lunar surface
Source: Blue Moon. ESCAPADE rides New Glenn as a launch path—robotic science on a Blue Origin rocket, not Blue Moon on Mars.
NASA — SLS / Artemis and the Mars science fleet
NASA runs two Mars-relevant stories in parallel: SLS + Artemis as a lunar / deep-space proving ground (crew systems, habitats, operations tempo), and a robotic Mars science fleet already on and around Mars (Curiosity, Perseverance, orbiters—mars.nasa.gov).
SLS public capability from NASA fact sheets dated December 2025:
- Block 1: >27 t to the Moon
- Block 1B: ~38 t
- Block 2: up to 46 t deep space
SLS is not a reusable Mars freighter. In a Mars conversation it is government heavy lift for exploration architecture and the Artemis path toward later crewed deep space. Bottlenecks: funding, flight rate, and crew deep-space systems beyond the booster.
CNSA — Tianwen-3 sample return
China’s public Mars push in this comparison is robotic sample return, not a settlement vehicle catalog.
Per Xinhua English reporting dated March 12, 2026, Tianwen-3 is described with launch around 2028 and return of at least 500 grams of Martian samples around 2031 (Xinhua).
Wire copy can lag; re-check CNSA or major wires before treating 2028 / 2031 as locked. Sample return remains a hard engineering race— ascent, rendezvous, Earth return—on the same synodic clock.
ESA — Rosalind Franklin / ExoMars (short note)
ESA’s Rosalind Franklin rover (ExoMars) is targeted for 2028 (esa.int). Robotic science lane—subsurface drill and European surface presence, not crew transport. Include it for completeness; do not inflate it into a settlement competitor row.
The 26-month constraint (same for everyone)
Efficient Earth-to-Mars departures cluster about every ~26 months. Miss a window and the next cheap opportunity is more than two years out—orbital mechanics, not branding.
SpaceX’s Mars materials couple architecture to that clock via tankers and window cadence. NASA, CNSA, and ESA robotic missions share the same rhythm. Lunar programs (Artemis, Blue Moon) only defer the day they meet that clock if they later pivot mass to Mars.

What changed since 2025 (short)
- SpaceX public cargo floor remains NET 2028 at $100M/t—an earliest commercial offer, not a flown Mars EDL demo at Starship scale.
- Blue Origin New Glenn / Blue Moon pages carry the payload and reuse figures above; ESCAPADE keeps New Glenn in the Mars science-launch conversation.
- NASA SLS fact sheets (Dec 2025) refresh Block 1 / 1B / 2 tonnage used here.
- CNSA Tianwen-3 ~2028 launch / ~2031 samples (≥500 g) entered wider English-wire circulation in March 2026.
- ESA Rosalind Franklin remains publicly targeted at 2028.
How we’ll update this page
- Re-check official SpaceX, Blue Origin, NASA, CNSA/wire, and ESA pages quarterly.
- Update the Specs as of line and changelog when numbers move.
- Keep lanes separate: do not promote a lunar lander into a Mars architecture row without a primary source.

If the destination is a second home—not only a flag—architecture, mass, and windows matter more than a news-cycle scoreboard. See The 4 Reasons Humanity Needs to Go to Mars and the event calendar.
Mars Dispatch reports the path to settlement with dated sources. We do not invent thrust, cost-per-kg, or landing years. When official pages change, this page should change with them.
