Approx Taken a toll: $113 billion (operational) up to ~$199 billion counting development
Agency: NASA
Timeline: 1981–2011
NASA’s Space Carry Program revolutionized human spaceflight with in part reusable shuttle — orbiters that carried space travelers and cargo. It worked 135 missions, propelled satellites, adjusted telescopes like Hubble, and built the ISS.
Science Focus
Cost Breakdown
Development and testing costs were enormous.
Operational costs, restoring orbiters after each flight, and security conventions included up.
Depending on how costs are calculated — with or without improvement costs — gauges extend from $113 billion to about $199 billion.
Science Focus
Legacy
Helped grow orbital science and fawning deployment.
Paved the way for commercial team and cargo programs.
Despite its accomplishments, the Carry program moreover endured tragedies (e.g., Challenger and Columbia), which underscored both designing dangers and the monetary toll of human spaceflight.
3. Apollo Space Program — ~$109–$160 Billion (inflation‑adjusted)
Approx Fetched: $109 billion authentic (approximately $160 billion+ balanced to today’s dollars)
Agency: NASA
Timeline: 1961–1972
The amazing Apollo program remains one of the most yearning and costly space endeavors. It conveyed on President John F. Kennedy’s objective to arrive people on the Moon and return them securely to Soil.
Science Focus
Why So Costly?
Development of the Saturn V rocket, command module, lunar lander, space explorer preparing, and Profound Space communication.
Establishing dispatch framework at Kennedy Space Center.
Technological advancement from scratch — computers, materials, navigation.
Apollo finished with six fruitful Moon arrivals and given tremendous logical returns counting lunar tests and Earth–Moon framework insights.
4. NASA’s Artemis Program — ~$93 Billion (continuous estimate)
Approx Taken a toll: ~$93 billion anticipated by mid‑2020s
Agency: NASA (Universal accomplices involved)
Timeline: 2017–present
Artemis points to return people to the Moon and set up a maintainable lunar nearness, with a long‑term see toward Damages. It incorporates advancement of the Space Dispatch Framework (SLS) rocket, Orion team capsule, lunar landers, and lunar foundation.

Why It’s Expensive
New rocket and capsule development.
Integration of worldwide and commercial partners.
Infrastructure for Portal lunar circle station and surface landers.
Though still in advance, Artemis is one of the most expensive programs, reflecting present day human spaceflight complexity.
5. Worldwide Situating Framework (GPS) Program — ~$12 Billion+
Approx Taken a toll: ~$12 billion beginning and update costs
Agency: U.S. Office of Defense & NASA support
Timeline: 1978–present
Often neglected in records of classic “space missions,” GPS is one of the most costly adj. route programs of all time and has changed life on Soil.
Science Focus
Why Cheaper Than ISS or Apollo?
It is a toady star grouping or maybe than a single lead exploration.
Built for worldwide route, defense, and commercial use.
Today, GPS supports worldwide coordinations, communications, mapping, and timing frameworks — making it one of the most impactful space programs per dollar spent.
6. Hubble Space Telescope — ~$16 Billion
Approx Fetched: ~$16 billion add up to (counting benefit missions)
Agency: NASA & ESA partnership
Timeline: 1990–present
Orbiting over Earth’s air, Hubble has changed cosmology. It has watched far off worlds, nebulae, and given profound bits of knowledge into infinite development.

Cost Details
Development, development, and launch.
Multiple Space Carry adjusting missions included billions more.
Operations over decades contribute to lifetime cost.
Hubble remains one of the most beneficial and deductively profitable observatories in history.
7. James Webb Space Telescope (JWST) — ~$10 Billion
Approx Taken a toll: ~$10 billion+
Agency: NASA with ESA and CSA collaboration
Timeline: Propelled 2021
The James Webb Space Telescope is the current lead space observatory — bigger and more able than Hubble. It watches essentially in infrared, permitting it to see more distant back into enormous history.
Science Focus
Cost Drivers
Ultra‑cold cryogenic systems.
Precision optics and arrangement mechanisms.
Deep‑space mission operations.
JWST’s cost reflected decades of arranging, innovative development, and a few delays—but its logical returns have as of now been profound.
8. NASA Defaces Meanderer Missions — Viking, Interest, Diligence (~$1–$3 Billion Each)
Robotic investigation of Damages has gotten to be more yearning — and costly — over time. Major Defaces missions include:
Viking 1 & 2 (~$1 Billion total)
Two shuttle (orbiter + lander) that looked for life and climate on Defaces in the 1970s. In spite of being decades ancient, Viking remains among the costliest mechanical missions.
Planetary Society
Curiosity Meanderer (~$2.5 Billion)
Launched in 2011, Interest has analyzed Martian topography, climate, and tenability.
mint
Perseverance Meanderer (~$2.7 Billion)
Including the Resourcefulness helicopter ramble, this mission looks for signs of antiquated microbial life and caches tests for future return.

Individually, these are not multibillion‑dollar alliance like ISS or Apollo — but in total they speak to a few of the most expensive interplanetary science missions ever.
9. Rosetta Comet Mission — ~$1.8 Billion
Approx Taken a toll: ~€1.3 billion (~$1.8 billion)
Agency: ESA (European Space Agency)
Timeline: 2004–2016
Rosetta was a spearheading comet meet mission that circled and landed a test (Philae) on Comet 67P/Churyumov–Gerasimenko — the to begin with mission of its kind.
Wikipedia
What Made It Costly
Long travel and complex direction counting Soil and Defaces flybys.
