Answer summary
William Shatner was 90 years old when he went to space. He flew aboard Blue Origin’s NS-18 mission on October 13, 2021, launched from the Corn Ranch facility near Van Horn, Texas. The suborbital flight crossed the U.S. definition of space (50 miles / 80 km) and made him the oldest person to reach space at the time. The following sections explain the mission, age calculation, and how this milestone compares to earlier spaceflights.
Flight details and mission context
NS-18 was Blue Origin’s third crewed flight and first with a guest astronaut. The vehicle is a New Shepard rocket and capsule designed for fully automated suborbital tourism flights. On October 13, 2021, the booster lifted off, the capsule separated, reached the edge of space, and descended under parachutes to a landing in West Texas.
Mission name and date
Blue Origin NS-18 launched on October 13, 2021, and lasted about 10 minutes from liftoff to landing. It was the nineteenth successful New Shepard mission and the first to include a non-professional astronaut as a primary crew member.
Crew composition and role
The crew for NS-18 included a mix of experienced astronauts and first-time space tourists. Shatner occupied a seat reserved for a guest astronaut, joining three professional Blue Origin astronauts. This configuration allowed a high-profile participant to fly on an early commercial human spaceflight mission.
Age at liftoff and significance
Because the flight occurred in October 2021, after Shatner’s birthday in March, he was 90 at liftoff. This age made him the oldest person to cross the U.S. boundary to space (50 miles) at the time of flight. The record applies to the U.S. criterion; by international (Fédération Aéronautique Internationale) standards, which set the boundary at 100 km, other individuals were older when they flew.
Age calculation details
Born on March 22, 1931, Shatner turned 90 in March 2021. The October 13 launch therefore occurred when he was 90 years, 6 months, and several days old. Age is typically expressed as completed years at the time of the event, so the answer is 90 years old.
Record context
Before NS-18, the oldest person to fly on a U.S.-certified spacecraft was John Glenn, who was 77 when he flew on STS-95 in 1998. By reaching space on Blue Origin’s vehicle, Shatner set a new benchmark for oldest space tourist under the 50-mile definition used by the U.S. government.
Defining the space boundary
Two organizations define the edge of space differently. The U.S. government and NASA recognize 50 miles (80 km) as the boundary for astronauts. The Fédération Aéronautique Internationale, which oversees world aeronautical records, uses 100 km (about 62 miles). Blue Origin’s flights cross both the U.S. and FAI boundaries, qualifying the crew for astronaut recognition under both criteria.
Vehicle performance and trajectory
The New Shepard booster reaches a speed of more than 3,300 mph (about Mach 5) and climbs above the 50-mile and 100-km marks before descending. The capsule separates near the peak of the trajectory, where passengers experience several minutes of weightlessness, then returns to Earth using braking rockets and parachutes.
Comparison with earlier space tourists
Commercial space tourism has included participants of varied ages. The first private spaceflight participants were younger, while later flights spanned a broad age range. Shatner’s NS-18 flight stands out for the age of the participant at the time, but many individuals have flown as professional astronauts at advanced ages.
Notable age milestones on spaceflights
- John Glenn (STS-95, 1998): 77 years old at launch; oldest person to orbit Earth at the time; U.S. record under the 50-mile definition.
- Yuri Malenchenko (Soyuz TMA-11, 2007): about 49 years old at launch; notable long-duration mission record-holder.
- William Shatner (Blue Origin NS-18, 2021): 90 years old at launch; oldest person to reach space by U.S. 50-mile criterion.
Mission outcome and public interest
NS-18 completed without incident, with the capsule landing upright in West Texas. The flight drew widespread media attention due to Shatner’s fame and age, highlighting the intersection of commercial spaceflight and popular culture. Public interest underscored broader questions about access to space for private citizens and the future of space tourism.

Clarifying common questions
Which space definition applies to Shatner’s flight?
The flight qualifies as spaceflight under both U.S. and international standards, crossing 50 miles and 100 km. Age records differ depending on which boundary is used, but the U.S. milestone is most commonly cited in media coverage of Shatner’s flight.
How does this compare to older astronauts on long-duration missions?
While Shatner was the oldest space tourist at the time, professional astronauts have flown on long-duration ISS missions at ages in the late 50s and early 60s. Those milestones involve extended missions in low Earth orbit, distinct from short-duration suborbital tourism flights.
Bottom line
William Shatner was 90 years old when he went to space on Blue Origin’s NS-18 mission in October 2021. This made him the oldest person to reach space under the U.S. 50-mile definition at the time, marking a notable moment in the history of commercial human spaceflight and public engagement with space tourism.
