Space is big. Really big. Most of us will never actually leave Earth’s atmosphere, which is kind of a bummer if you grew up watching sci-fi movies or staring at the moon through a cheap telescope. But NASA has this clever way of making the vastness of the solar system feel a little more personal. It's their "Send Your Name to Mars" campaign. Honestly, it sounds like a gimmick. You might think, "What’s the point of a digital file sitting on a cold, dusty planet 140 million miles away?"
It matters because it's a physical connection.
When you sign up to send your name to Mars, NASA doesn't just store it on a hard drive in a basement in Maryland. They use an electron beam to stencil your name onto a microchip. This isn't some marketing metaphor; it's literal engineering. We’re talking about text smaller than one-thousandth the width of a human hair. That chip gets bolted onto the chassis of a rover, like Curiosity or Perseverance, and it actually makes the trip. It survives the vibration of launch, the vacuum of space, and the "seven minutes of terror" during entry, descent, and landing.
How the NASA "Boarding Pass" System Actually Works
The process is surprisingly straightforward, which is probably why millions of people have already done it. You go to the official NASA Mars Exploration website. You put in your name, country, and zip code. Boom. You get a digital "boarding pass" that looks suspiciously like something you’d use at an airport, complete with frequent flyer miles.
NASA started this in a big way with the InSight lander and then ramped it up for the Mars 2020 mission. For Perseverance, they managed to squeeze 10,932,293 names onto three chips. These chips are about the size of a fingernail. They are tucked away under a protective plate on the rover’s aft crossbeam. It’s a quiet, tiny monument to human curiosity.
Why do they do it? It’s not just for the "likes" on social media. Public engagement is the lifeblood of space exploration. NASA knows that if you feel like you have a "stake" in the mission—even if that stake is just a microscopic engraving of your name—you’re more likely to follow the mission's progress. You’ll care when the rover finds an interesting rock in Jezero Crater. You’ll be invested in whether the Sample Retrieval Lander actually makes it to the surface in the late 2020s.
The Microchip Technology Behind Your Name
Let’s talk about the tech for a second because it's pretty cool. The Microdevices Laboratory at NASA’s Jet Propulsion Laboratory (JPL) is responsible for this. They use an electron beam lithography machine. This is the same kind of tech used to manufacture high-end computer processors.
The "lines" of the letters are incredibly thin.
If you were standing on Mars and had a powerful enough microscope, you could read every single name. Because Mars has a very thin atmosphere and no magnetic field, the environment is harsh. Radiation is a real problem. However, these chips are made of silicon with a protective coating, meaning they could theoretically last for millions of years. Long after the rover’s batteries die and its wheels seize up, your name will still be there. It’s a weird form of digital immortality.
Is It Too Late to Send Your Name to Mars?
This is where people get confused. NASA doesn't keep the window open forever. They usually open the "boarding pass" registration months or even years before a specific launch. For the Perseverance rover, the deadline passed long ago.
However, they are almost always collecting names for the next big thing.
Right now, NASA is looking ahead to future missions, including the Mars Sample Return (MSR) campaign. If you go to the site and the current mission registration is closed, they usually have a "Sign up for the next mission" option. You’ll still get your frequent flyer miles. Some people have millions of miles now because they’ve sent their names on the Orion EFT-1 flight, InSight, and Perseverance. It’s like a very nerdy loyalty program.
Common Misconceptions About the Program
One big myth is that this costs money. It doesn't. It is completely free. If you see a website charging you to send your name to Mars, it is a scam. Period. NASA is a government agency funded by taxpayers; they aren't in the business of selling digital boarding passes.
Another thing people get wrong is thinking their name is being "beamed" to Mars via radio waves. While NASA does transmit data to the rovers daily, the "Send Your Name" program specifically refers to the physical microchips attached to the hardware before it leaves Earth. If you sign up after a rover has already launched, your name isn't magically teleported to the robot. It waits on a server until the next piece of hardware is ready to fly.
Why Space Agencies Care About Your Name
It sounds a bit soft, doesn't it? A multi-billion dollar engineering project carrying a list of names. But space exploration is inherently a human endeavor. Dr. Thomas Zurbuchen, a former associate administrator for NASA’s Science Mission Directorate, often spoke about how these missions represent the "spirit of exploration."
By including the public, NASA turns a cold scientific machine into a vessel for human hopes.
It’s also about education. Teachers use the boarding passes to get kids excited about STEM. Imagine being eight years old and having a piece of paper that says your name is currently on another planet. That’s a powerful hook. It’s the kind of thing that turns a kid into a future engineer or astrophysicist.
The Logistics of Future Missions
We are entering a very busy era for Mars. It’s not just NASA anymore. The European Space Agency (ESA) has the ExoMars program, and various international partners are looking at the Red Planet. While NASA is the most famous for the "name" program, keep an eye on other agencies. They often do similar outreach.
The next massive milestone is the Mars Sample Return. This is a complex "relay race" involving a lander, a fetch rover, and an ascent vehicle that will blast off from the Martian surface. It’s one of the most ambitious things humans have ever tried. Getting your name on one of those components is like getting a front-row seat to history.
How to Check Your "Frequent Flyer" Status
If you've done this before but lost your digital pass, NASA has a "Frequent Flyer" log-in. You just need your name and the email address you used originally. It’ll show you all the missions you’ve "participated" in and your total mileage.
- Go to the NASA Mars "Send Your Name" homepage.
- Look for the "Frequent Flyer" or "Find My Boarding Pass" link.
- Enter your details to retrieve your history.
It’s a fun way to track the missions. For example, the flight from Earth to Mars is roughly 300 million miles depending on the planetary alignment. Those miles add up fast.
The Reality of Mars Exploration
Let’s be real for a second. Mars is a graveyard for robots. About half of all missions sent to the Red Planet have failed. They crash, they disappear, or they burn up in the atmosphere. When you send your name to Mars, there is no guarantee it actually makes it to the surface in one piece.
But that’s part of the risk.
When Perseverance landed in February 2021, the collective sigh of relief from the millions of people who sent their names was palpable. If the rover had crashed, those chips would have been pulverized. The stakes make it more exciting. It’s not a digital file in a cloud; it’s a physical object on a dangerous journey.
Beyond Names: What Else Goes to Mars?
Names aren't the only "extras" on these rovers. NASA often includes "easter eggs." On Perseverance, there’s a small plate depicting the Earth, the Sun, and Mars, with the words "Explore as one" written in Morse code in the sunbeams. There’s also a tribute to healthcare workers who fought the COVID-19 pandemic during the rover's assembly.
The "Send Your Name" chip is part of this tradition of carrying human culture into the void. It follows in the footsteps of the Golden Record on the Voyager probes or the plaques on the Pioneer spacecraft. We want to say, "We were here, and we were curious."

Practical Steps to Get Involved
If you want to be part of the next mission, don't wait for the launch news to hit the front page. By then, the hardware is usually already sealed in the fairing and sitting on the launchpad.
Visit the official NASA Mars site regularly. Look for the "Participate" or "Public Outreach" sections. Usually, they open name registration for "Future Missions" even when a specific mission hasn't been named yet.
Save your boarding pass. Print it out or save the PDF. It contains a unique member ID. This ID is your key to the frequent flyer program.
Follow the mission updates. Once you’ve signed up, follow the specific rover’s social media accounts. NASA’s JPL team does a great job of giving the rovers a "personality." When the rover reaches a new milestone, like its first drive or its first rock core sample, you’ll feel a much stronger connection to the data.
Check for other NASA programs. Sometimes they do similar things for missions to the Moon (Artemis) or the moons of Jupiter (Europa Clipper). The "Send Your Name" concept is becoming a standard part of NASA’s outreach toolkit.
Space is no longer just for astronauts and billionaires. Small gestures like this bridge the gap. It's a reminder that while the rovers are doing the science, they are doing it for all of us back here on the "Pale Blue Dot."
Sign up as soon as a window opens. These programs often have a cap or a strict deadline based on the engineering schedule for the microchips. Once the chip is etched and installed, that’s it. There’s no "adding" a name later. Get your info in the system early to ensure you're on the next silicon chip headed for the stars.
