Timeline: A Historical Look at Every Mission to Mars
Within our Solar System, Mars is one of the most similar planets to Earth—both have rocky landscapes, solid outer crusts, and cores made of molten rock.
Because of its similarities to Earth and proximity, humanity has been fascinated by Mars for centuries. In fact, it’s one of the most explored objects in our Solar System.
But just how many missions to Mars have we embarked on, and which of these journeys have been successful? This graphic by Jonathan Letourneau shows a timeline of every mission to Mars since 1960 using NASA’s historical data.
A Timeline of Mars Explorations
According to a historical log from NASA, there have been 48 missions to Mars over the last 60 years. Here’s a breakdown of each mission, and whether or not they were successful:

The first mission to Mars was attempted by the Soviets in 1960, with the launch of Korabl 4, also known as Mars 1960A.
As the table above shows, the voyage was unsuccessful. The spacecraft made it 120 km into the air, but its third-stage pumps didn’t generate enough momentum for it to stay in Earth’s orbit.
For the next few years, several more unsuccessful Mars missions were attempted by the USSR and then NASA. Then, in 1964, history was made when NASA launched the Mariner 4 and completed the first-ever successful trip to Mars.
The Mariner 4 didn’t actually land on the planet, but the spacecraft flew by Mars and was able to capture photos, which gave us an up-close glimpse at the planet’s rocky surface.
Then on July 20, 1976, NASA made history again when its spacecraft called Viking 1 touched down on Mars’ surface, making it the first space agency to complete a successful Mars landing. Viking 1 captured panoramic images of the planet’s terrain, and also enabled scientists to monitor the planet’s weather.
Vacation to Mars, Anyone?
To date, all Mars landings have been done without crews, but NASA is planning to send humans to Mars by the late 2030s.
And it’s not just government agencies that are planning missions to Mars—a number of private companies are getting involved, too. Elon Musk’s aerospace company SpaceX has a long-term plan to build an entire city on Mars.
Two other aerospace startups, Impulse and Relativity, also announced an unmanned joint mission to Mars in July 2022, with hopes it could be ready as soon as 2024.
As more players are added to the mix, the pressure is on to be the first company or agency to truly make it to Mars. If (or when) we reach that point, what’s next is anyone’s guess.

Charted: What are Retail Investors Interested in Buying in 2023?
What key themes and strategies are retail investors looking at for the rest of 2023? Preview: AI is a popular choice.

Charted: Retail Investors’ Top Picks for 2023
U.S. retail investors, enticed by a brief pause in the interest rate cycle, came roaring back in the early summer. But what are their investment priorities for the second half of 2023?
We visualized the data from Public’s 2023 Retail Investor Report, which surveyed 1,005 retail investors on their platform, asking “which investment strategy or themes are you interested in as part of your overall investment strategy?”
Survey respondents ticked all the options that applied to them, thus their response percentages do not sum to 100%.
Where Are Retail Investors Putting Their Money?
By far the most popular strategy for retail investors is dividend investing with 50% of the respondents selecting it as something they’re interested in.
Dividends can help supplement incomes and come with tax benefits (especially for lower income investors or if the dividend is paid out into a tax-deferred account), and can be a popular choice during more inflationary times.
Investment Strategy | Percent of Respondents |
---|---|
Dividend Investing | 50% |
Artificial Intelligence | 36% |
Total Stock Market Index | 36% |
Renewable Energy | 33% |
Big Tech | 31% |
Treasuries (T-Bills) | 31% |
Electric Vehicles | 27% |
Large Cap | 26% |
Small Cap | 24% |
Emerging Markets | 23% |
Real Estate | 23% |
Gold & Precious Metals | 23% |
Mid Cap | 19% |
Inflation Protection | 13% |
Commodities | 12% |
Meanwhile, the hype around AI hasn’t faded, with 36% of the respondents saying they’d be interested in investing in the theme—including juggernaut chipmaker Nvidia. This is tied for second place with Total Stock Market Index investing.
Treasury Bills (30%) represent the safety anchoring of the portfolio but the ongoing climate crisis is also on investors’ minds with Renewable Energy (33%) and EVs (27%) scoring fairly high on the interest list.
Commodities and Inflation-Protection stocks on the other hand have fallen out of favor.
Come on Barbie, Let’s Go Party…
Another interesting takeaway pulled from the survey is how conversations about prevailing companies—or the buzz around them—are influencing trades. The platform found that public investors in Mattel increased 6.6 times after the success of the ‘Barbie’ movie.
Bud Light also saw a 1.5x increase in retail investors, despite receiving negative attention from their fans after the company did a beer promotion campaign with trans influencer Dylan Mulvaney.
Given the origin story of a large chunk of American retail investors revolves around GameStop and AMC, these insights aren’t new, but they do reveal a persisting trend.
