how big is orion spacecraft

The Orion spacecraft, NASA's advanced crew capsule for deep-space missions like Artemis, measures about 67 feet (20.4 meters) tall when fully stacked with its crew and service modules.
This makes it significantly larger than the Apollo command module, designed for longer missions and up to four astronauts.

Key Dimensions

Here's a breakdown of the Orion spacecraft's main size specs from official NASA data:

[9][1] [3][7][1] [1]

Component	Height	Diameter	Other Metrics
Full Stack (Crew + Service Modules)	67 ft (20.4 m)	16.5 ft (5 m) base	Gross liftoff mass: 78,000 lbs
Crew Module	11-15.7 ft (3.3-4.8 m)	16.5 ft (5 m)	Habitable volume: 316 cu ft (9 m³); Pressurized: 690 cu ft
Service Module	~15 ft	16.5 ft (5 m)	Propellant mass: up to 19,000 lbs

These dimensions allow Orion to support extended lunar trips, with room for crew quarters, supplies, and advanced avionics—imagine a high-tech RV for space, but built to withstand reentry at 25,000 mph.

Compared to Apollo

• Orion Crew Module : 16.5 ft diameter vs. Apollo's 12.8 ft—50% wider for better living space (9 m³ habitable per recent Artemis II notes vs. Apollo's 6.2 m³).

• Full vehicle : Orion's 67 ft stack dwarfs Apollo's ~36 ft command/service combo, enabling Mars potential.

• Forum chatter on Reddit highlights Orion's "oversized" design for mass efficiency debates, but it's optimized for safety and duration.

Recent Context (Artemis Era)

As of Artemis I's 2022 success and Artemis II prep for lunar orbit this year, Orion's size supports four astronauts with 9 m³ habitable volume —like a cozy campervan shared among friends, per Canadian Space Agency posts. No major size changes reported in 2026 updates; it's locked for reliability.

TL;DR : Orion stands 67 ft tall, 16.5 ft wide, with a roomy crew module for moon voyages—bigger and bolder than Apollo for tomorrow's explorers.
