Download Software Used to Get Rovers to the Red Planet

Watching our Perseverance rover safely land on the surface of Mars is the kind of historic feat that gets our adventure-loving hearts racing.

Launching and landing rovers on Mars requires overcoming challenges like defying gravity on two planets, surviving the extreme heat of atmospheric entry, and avoiding rocky obstacles. This takes more than just rocket science – it takes incredible software too.

Did you know that some of the same tried and tested software that helped ensure a safe arrival for Perseverance (and its predecessor, Curiosity) can be downloaded – by you...for free...right now?

Our 2021-22 Software Catalog is full of codes made for space that can be used by entrepreneurs, teachers, gamers, or just about anyone. Whether you are curious about the Martian atmosphere, want to visualize the inside of a volcano, or have an application we’ve never even considered, our software may be able to help. Check out our full site, updated regularly with the latest codes available for download.

Here are a few examples of what you could do with our software!

1. Simulate the Martian atmosphere to prepare spacecrafts for landing

To prepare for exactly what a spacecraft will face on landing day, no matter the location scientists choose, we created software that simulates the Martian atmosphere. The code, Mars (GRAM), is now available to anyone.

We also have a version that simulates Earth's atmosphere, allowing users (especially those in the world of drone design) a way to replicate and design for, potentially dangerous conditions without ever stepping away from the computer.

2. Explore the Red Planet virtually from home with help from the Curiosity rover team

Originally developed for scientists and engineers working on the Curiosity rover mission, OnSight allowed the team a virtual way to walk on and look around Mars. Using an immersive display, such as a virtual reality headset, scientists could see the Red Planet the way a rover would.

This software can also be used to provide virtual experiences of places here on Earth, such as caves and lava fields.

3. Dodge disasters with a risk management tool made for space missions

When preparing for complex space missions, like the upcoming Mars Sample Return mission, it’s crucial to examine how different elements, independently and collectively, impact the probability of success.

But risk management has become an important tool for businesses of all disciplines, from engineering to accounting – and the Space Mission Architecture and Risk Analysis Tool (SMART) could help.

Sound interesting? The NASA software catalog has these and more than 800 additional codes ready for download.

You can also follow our Technology Transfer program on Twitter to learn more about software and technology that can be put to use on Earth.

One Hot Year after Another

Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s.

Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane. 

Heat and the energy it carries are what drive our planet: winds, weather, droughts, floods, and more are expressions of heat. The right amount of heat is even one of the things that makes life on Earth possible. But too much heat is changing the way our planet’s systems act.

My World’s on Fire

Higher temperatures drive longer, more intense fire seasons. As rain and snowfall patterns change, some regions are getting drier and more vulnerable to damage, setting the stage for more fires.

2020 saw several record-breaking fires, both in Australia in the beginning of the year, and in the western U.S. through northern summer and fall. Smoke from fires in both regions reached so high into the atmosphere that it formed clouds and continues to travel around the globe today.

In the Siberian Arctic, unusually high temperatures helped drive at least 19 fires in the region. More than half of them were burning peat soil – decomposed organic materials – that stores a lot of carbon. Peat fires release vast amounts of carbon into the atmosphere, potentially leading to even more warming.

The Water’s Getting Warm

It wasn’t just fire seasons setting records. 2020 had more named tropical storms in the Atlantic and more storms making landfall in the U.S. than any hurricane season on record.

Hurricanes rely on warm ocean water as fuel, and this year, the Atlantic provided. 30 named storms weren’t the only things that made this year’s hurricane season notable.

Storms like Eta, Delta, and Iota quickly changed from smaller, weaker tropical storms into more destructive hurricanes. This rapid intensification is complicated, but it’s likely that warmer, more humid weather – a result of climate change – helps drive it.

The Ice Is Getting Thin

Add enough heat, and even the biggest chunk of ice will melt. That’s true whether we’re talking about the ice cubes in your glass or the vast sheets of ice at our planet’s poles. Right now, the Arctic region is warming about three times faster than the rest of our planet, which has some major effects both locally and globally.

This year, Arctic sea ice hit a near-record low. Sea ice is actually made of frozen ocean water, and it grows and thaws with the seasons, typically reaching an annual minimum extent in September.

Warmer ocean water led to more ice melting this year, and 2020’s annual minimum extent continued a long trend of shrinking Arctic sea ice extent.

A Long Trend

We study Earth and how it’s changing from the ground, the sky, and space. Using data from sensors all around the planet, we calculate the global average temperature, working with our partners at NOAA.

Many other organizations also track global temperature using their own instruments and methods, and they all match remarkably well. The last seven years were the hottest seven years on record. Earth is getting warmer.

We also study the effects of increasing temperatures, like the melting sea ice and longer fire seasons mentioned above. Additionally, we can study the cause of climate change from space, with a bird’s eye view of increasing carbon in the atmosphere.

The planet is changing because of human activities. We’re working together with other agencies to monitor changes and understand what this means for people in the future.
