The Cost To Travel To the Moon, Mars and Beyond

Joel Anderson

Whether you’re interested in boldly going where no man has gone before or simply want to stop by the moon for the first time in a few decades, traveling beyond our world has been a dream of many for generations. As fewer and fewer corners of our own globe remain unexplored, mankind has begun to look beyond for new worlds to explore.

However, the cost of venturing forth into the great recesses of space isn’t cheap. If humans are going to really explore our own solar system — let alone whatever is beyond — they had better be ready to spend, and spend lavishly. Because whether it’s a self-contained moon colony or a giant solar sail to carry a ship to Alpha Centauri, the price tag associated with turning sci-fi into reality is steep indeed.

So, here are the costs of space exploration — hypothetical or otherwise — in our own solar system and beyond its boundaries.

Cost To Launch Stuff Into Space

  • Cost: $10,000 per pound

One of the biggest costs for any space mission comes with just trying to escape the gravitational pull of the Earth. And before you really begin to dream about massive spacecraft traveling far away, you should know that weight is a primary concern for anything you plan to shoot into space. The current cost to put something into orbit is a staggering $10,000 per pound. So, while it might seem a bit draconian that NASA limits astronauts to just 1 1/2 pounds of personal items, it’s also worth remembering that NASA spends $15,000 just to send that stuff along.

Cost To Go To the Moon — the First 9 Times

  • Cost: $140 billion

While a lot of the technology has changed since the 1960s, and costs have almost certainly dropped over the past 60 years, projecting future costs should consider some from the past. As such, the cost of the Apollo Program and its nine manned missions to the moon is a good starting point.

The U.S. government spent — independent of infrastructure costs — $23.6 billion on manned spaceflight from 1959 to 1973. Taking that as 1973 dollars, that’s roughly equivalent to a little over $140 billion in 2019 dollars, or about $9 billion a year. Which, as far as government costs go, is not really all that much. For comparison, that would be about 3.4% of the total 2018 federal budget, and as an annual cost would require increasing outlays by about 0.2%.

Cost To Go To Space, Come Back and Go Again

  • Cost: $1.56 billion per mission

The next stage of space exploration included the U.S. Shuttle Program, which used spacecraft that could venture into space and return to Earth. When it was first announced in 1972, the program was intended to reduce costs, with some imagining a future where space flights occurred once a week and cost as little as $20 million. Oops. The space shuttle program was eventually shuttered after 134 flights at a cost of $209 billion. It never made more than nine flights in a year, and at a cost of over $1.5 billion a flight, it was ultimately 75 times more per flight than the proposed $20 million.

Cost of a Space Station

  • Cost: $125 billion

Traveling to distant worlds will most likely require setting out from a space station, given the incredible cost and difficulty of escaping Earth’s gravity into orbit. As such, a space station is likely to be an important staging ground for some future missions. The total cost for the current International Space Station (ISS) has only been estimated by the European Space Station, which pegged it at €100 billion — or $112.8 billion — in 2013. When adjusted for 2019, the cost only goes up. And that cost likely includes the $3 billion-$4 billion a year that the United States alone contributes to the station’s annual maintenance — roughly half of NASA’s total budget.

Cost To Resupply a Space Station

  • Cost: almost $200 million per mission

The cost of the space shuttle program ultimately brought it to an end as a new raft of private companies have started offering to contract space launches. In 2008, NASA awarded contracts to Elon Musk’s SpaceX and Orbital ATK — now owned by Northrop Grumman — worth a total of $5.9 billion for some 31 resupply missions. That comes to just under $200 million a mission to keep the space station up and running.

Cost To Visit Space If You’re Not an Astronaut

  • Cost: $52 million a seat

The public-private partnerships developing between NASA and Boeing, SpaceX and others are also creating some intriguing possibilities for space tourism. In the near term, the shuttles being sent to resupply the ISS won’t have NASA taking up every seat with its personnel. So, when NASA doesn’t buy all the seats, someone who isn’t an astronaut can just tag along for a chance to visit space. The price tag? SpaceX is planning on selling the seats for a mere $52 million apiece. No word on whether or not that comes with a complimentary package of peanuts.

Places Closer to Home: The Most Secluded Places on Earth

Cost To Go To the Moon ... Again

  • Cost: $22.6 billion

President Donald Trump’s administration has made a return to the lunar surface a priority for NASA, asking for $21 billion for the Artemis program in its 2020 budget. Then, it boosted that request by $1.6 billion just two months later when it asked to accelerate the program’s target date to 2024.

Cost To Travel To Mercury

  • Cost: $1.9 billion

It’s not entirely clear why a human might want to travel to Mercury, where temperatures can range from minus 280 degrees Fahrenheit at the poles to 800 degrees Fahrenheit in sunlight, but researchers have sent spacecraft to the closest planet to the sun and they’re planning to do so again. The first European mission to Mercury launched last year at a cost of some 1.7 billion euros — or about $1.9 billion.

Cost To Travel To Venus

  • Cost: $147.7 million

Venus has seen a fair bit of human hardware over the years. The Soviet Union made several successful landings on its surface with a probe and NASA’s Magellan mission spent four years mapping 98% of the planet’s surface. However, for the best understanding of what the cost to return would come to, the European Space Agency’s Venus Explorer launched in 2005 and spent nine years studying the nearby planet until it ran out of propellant. All told, the Venus Express proved to be very cost-effective, costing just $110 million in 2005, or $147.7 million in 2019 dollars.

Cost To Travel To Earth

  • Cost: Surprisingly cheap

Go for the liquid water, stay for the night (and all other forms of) life.

Cost To Travel To Mars

  • Cost: $828.8 million

While the current question might be what it costs to send a person to Mars, the cost of simply getting to the red planet is pretty clear — there have been a multitude of missions sending a craft to the planet and onto its surface.

The first such visits were the Viking program in the 1970s that sent two probes to Mars at a total cost of roughly $1 billion — a little over $4.5 billion adjusted for inflation. However, NASA was clearly just dipping its toe in the pool back then because it’s been back repeatedly in both the Mars Scout Program and the Mars Exploration Rover program. NASA’s present mission to Mars, the InSight Mars Lander, touched down on the red planet last year and has a current price tag of $828.8 million.

Cost To Travel To Jupiter

  • Cost: $4.7 billion

The solar system’s largest planet has been the focus of several exploratory missions ever since Pioneer 10 and 11 whizzed past it for the first time in the early 1970s. Today, there are more missions planned to visit the gas giant and some of its 79 moons, including NASA’s planned mission to explore the moon of Europa, which appears to have the potential of supporting life. Just remember, if you’re ever asked to be part of a mission to Jupiter with a supercomputer named Hal, say no. Some things aren’t worth it at any price.

Cost To Travel To Saturn

  • Cost: $3.9 billion

Journeys to Saturn might just be an example of seeing a major landmark before it’s gone. After all, NASA recently updated its projections to reveal that the rate of “ring drain” is a “worst-case scenario.” Granted, it will take 100 million years before the iconic rings are gone. The reason scientists were able to make those predictions was the wealth of data provided by the Casini space probe over 20 years — a mission that had a total cost of $3.9 billion.

Cost To Travel To Uranus

  • Cost: $2.19 billion (hopefully)

The cost to visit Uranus is an important question — the original proposal to send a probe there was scrapped in the 1970s when NASA’s budget was cut and the program’s $700 million price tag made it untenable. While the program was salvaged in the form of the Voyager program, the 50,000-or-so miles that Voyager II came from Uranus is as close as any man-made object has gotten. And while NASA has made Uranus a relatively low-priority goal, it does still have some plans in the works. In 2015, NASA started a feasibility study of a mission to Uranus that could be completed on a budget of $2 billion, inflation-adjusted.

Cost To Travel To Neptune

  • Cost: $500 million

Much like Uranus, the closest mankind has ever gotten to Neptune is a distant flyby by Voyager in 1989. What’s more, there hasn’t been a lot of effort to launch an effort to get back. But, there has recently been a spark of hope for big-time Neptune fans as the Trident Proposal was submitted as part of NASA’s highly competitive Discovery program for missions with a budget of $500 million or less.

Cost To Travel To Pluto

  • Cost: $500 million

Before anyone starts shouting, one should be interested in exploring Pluto whether it’s technically a planet or not. And that is just what NASA did in 2015 when the New Horizons probe flew by the distant planet. It was important that the probe traveled when it did, as the next time Pluto’s orbit would be close enough would be in another 200 years. Fortunately for NASA, it managed to push the project through and launch inside of its window — all with a price tag of just $500 million.

Cost To Travel To an Asteroid

  • Cost: $150 million

Of course, visiting Pluto does bring up the question of what it might cost to visit other, ahem, nonplanets. The most recent journey was performed by the Japanese Space Agency JAXA and successfully landed two hopping robots on the asteroid Ryugu, where they will examine the floating rock to learn more about asteroids. The total cost of the mission? That would be 16.4 billion yen, or about $150 million.

Cost To Travel Beyond Our Solar System

  • Cost: $5.4 billion

The first spacecraft to leave the solar system and actually enter interstellar space was Voyager 1, which left our solar system in 2012. That should give you a sense of why interstellar travel is so difficult — the probe was launched in 1977. However, if all you want to do is get to the great beyond, the cost of the entire Voyager program came to $865 million in 1972, the equivalent of about $5.4 billion today.

Cost To Partake In Interstellar iTunes

  • Cost: $98

One of the more interesting wrinkles to the story of the Voyager craft is what went along with the spacecraft when scientists realized they would be flying off into distant worlds mankind might never know: a record. Specifically, a gold-plated record filled with everything from whale songs to bluesman Blind Willie Johnson — an attempt to encapsulate the planet Earth and the human race through sound. And while the original records are, far, far away, there was a Kickstarter campaign to release the contents of the record on vinyl, and you can now get it for $98.

Cost of Modern Interstellar Spaceflight

  • Cost: $20 trillion to $174 trillion

Of course, the fact that the only thing that’s ever gotten out of the solar system was built in the 1970s presents certain limitations. One potential plan — also from the 1970s — with a goal of actually seeking out life elsewhere in the universe was called Project Daedalus. Developed by the British Interplanetary Society, it would fly to Barnard’s Star (six light years away) and explore the solar system there. Unfortunately, though, this might remain a dream for quite a while longer: The estimated cost of the project ranges from $20 trillion to $174 trillion.

Cost To Colonize the Moon

  • Cost: $10 billion

Of course, maybe instead of trying to venture to places so far away that would take multiple human lifetimes to reach — you could consider setting up camp somewhere closer. If you’re talking about the colonization of the moon — and some people are — NASA astrobiologist Chris McCay estimates that a small, starter moon base could be had for as little as $10 billion.
