As of 2026, the surviving NASA space shuttles are on permanent display at museums: Discovery at the Smithsonian’s Udvar-Hazy Center in Virginia, Atlantis at Kennedy Space Center in Florida, Endeavour at the California Science Center in Los Angeles, and Enterprise at the Intrepid Sea, Air & Space Museum in New York City.
What happened to the 5 space shuttles?
NASA built five operational orbiters—Discovery, Atlantis, Endeavour, Challenger, and Columbia—plus the test article Enterprise; Columbia and Challenger were lost with crews in 2003 and 1986, while the remaining three were retired to museums by 2012.
Enterprise never left Earth’s atmosphere, so it never flew in space. Now it sits at the Intrepid Sea, Air & Space Museum in New York City. Discovery, Atlantis, and Endeavour wrapped up their last flights in 2011 before heading to the Smithsonian, Kennedy Space Center Visitor Complex, and California Science Center, respectively.
How many space shuttles have been lost in NASA history?
Two space shuttles—Challenger in 1986 and Columbia in 2003—were lost during flight, killing a total of 14 astronauts across both accidents.
The Space Shuttle Program completed 135 missions before shutting down in July 2011. Both disasters forced long pauses for safety reviews and upgrades, which ultimately helped end the program.
How many space shuttles still exist?
Four of the five spaceworthy orbiters—Discovery, Atlantis, Endeavour, and Enterprise—are in museums; Challenger and Columbia were destroyed in accidents.
Enterprise, the prototype that only flew in atmospheric tests, now lives at the Intrepid Museum in New York. The rest are preserved as historical artifacts for the public to see.
Has anyone been lost in space?
Eighteen people have died in spaceflight-related incidents: 14 in the Challenger and Columbia accidents, plus four on the ground during Apollo 1 preparations in 1967.
These fatalities include all crew members on both shuttle missions and the Apollo 1 crew who died in a cabin fire during a pre-launch test. Since Apollo 17 in 1972, no astronauts have died during spaceflight missions.
Why don’t they use space shuttles anymore?
NASA retired the Space Shuttle Program in 2011 due to high operational costs, safety vulnerabilities exposed by the Columbia accident, and a shift toward the Orion capsule and Commercial Crew vehicles for deep-space missions.
Each flight cost about $1.5 billion on average, and turnaround times were painfully slow. The final shuttle mission, STS-135, landed on July 21, 2011.
How long did the Challenger crew survive?
Investigators estimate the Challenger crew remained conscious for at least 10 seconds after vehicle breakup, with some emergency oxygen packs activated despite the cabin’s rapid depressurization.
NASA’s analysis suggests the crew didn’t die instantly but likely lost consciousness as the cabin fell toward the ocean. Recovery of remains later confirmed the crew compartment hit the water intact.
Were the bodies of the Challenger crew recovered?
NASA recovered the remains of all seven Challenger astronauts and retrieved the crew compartment from the ocean floor.
The recovery took months because of the deep-sea conditions. The debris was taken to Kennedy Space Center for investigation before being stored.
Did NASA know Columbia was doomed?
Mission managers did not know Columbia’s left wing was fatally damaged by foam debris during launch, and they chose not to request satellite imagery that could have confirmed the damage.
Engineers asked for imagery, but their requests were denied due to limited resources and the assumption the damage wasn’t critical. Columbia’s breakup during re-entry exposed the fatal flaw, leading to major safety changes.
Did they ever find the bodies of the Columbia shuttle astronauts?
All seven Columbia astronauts’ remains were recovered across East Texas and Louisiana following the February 1, 2003, breakup.
Recovery teams spent months collecting debris and human remains over a wide area. The crew compartment’s impact site was near Hemphill, Texas, and the remains helped investigators piece together what went wrong.
Could the shuttle go to the moon?
No—NASA confirmed the Space Shuttle was designed only for low-Earth orbit and lacked the propulsion and thermal protection needed for lunar missions.
The shuttle’s maximum altitude topped out around 600 kilometers—nowhere near the 384,400 kilometers to the moon. Any trip to the moon would need a dedicated launch vehicle and crew capsule, like the Apollo-era Saturn V or today’s Space Launch System.
How much did a space shuttle cost?
Each Space Shuttle mission cost an average of $450 million in 2020 dollars, with the entire program spending about $209 billion over its lifetime.
| Component | Original 1970s $ | 2026 $ |
|---|
| Orbiter alone | $1.2B | $5.4B |
| External Tank | $50M | $230M |
| Solid Rocket Boosters (pair) | $45M | $205M |
| Mission operations | $300M | $1.4B |
These numbers cover development, upgrades, and operations. By the program’s end, NASA was spending roughly $1.6 billion per flight when adjusted for inflation.
Would a body decompose in space?
No—without oxygen or microbes, a body in space would not undergo normal decomposition; it would either freeze or mummify depending on exposure to heat sources.
In a sealed spacesuit with leftover oxygen, decomposition would only continue until the oxygen ran out—usually within hours. Bodies exposed to vacuum freeze solid because there’s no atmospheric pressure and it’s brutally cold.
Can I jump off the moon?
You cannot jump off the moon—its escape velocity is about 2.38 km/s, far beyond human capability.
Even with a super-powered spring-assisted suit, a person’s jump speed would max out around 5–10 m/s—nowhere near enough to reach lunar orbit. The moon’s gravity is one-sixth of Earth’s, so you can jump higher and farther here, but you’re still stuck on the surface.
What do astronauts do when not in space?
Astronauts spend their time on Earth conducting scientific research, training for future missions, supporting mission control, and engaging in public outreach and education.
They also keep up with intense fitness and medical checkups to stay mission-ready. Daily workouts mimic what they do in orbit to avoid muscle wasting and bone loss.
Why did NASA stop going to the moon after Apollo 17?
NASA ended crewed lunar missions after Apollo 17 due to rapidly rising costs, shifting national priorities, and the conclusion of the Cold War space race.
Each Apollo mission cost around $1.2 billion in 1970s dollars—about $9 billion today. With no urgent need to beat the Soviets to the moon anymore, Congress funneled money into the Space Shuttle, Skylab, and later the International Space Station instead.
