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.

Rocket Launches and Rising Seas
At NASA, we’re not immune to effects of climate change. The seas are rising at NASA coastal centers – the direct result of warming global temperatures caused by human activity. Several of our centers and facilities were built near the coast, where there aren’t as many neighbors, as a safety precaution. But now the tides have turned and as sea levels rise, these facilities are at greater risk of flooding and storms.
Global sea level is increasing every year by 3.3 millimeters, or just over an eighth of an inch, and the rate of rise is speeding up over time. The centers within range of rising waters are taking various approaches to protect against future damage.
Kennedy Space Center in Florida is the home of historic launchpad 39A, where Apollo astronauts first lifted off for their journey to the Moon. The launchpad is expected to flood periodically from now on.
Like Kennedy, Wallops Flight Facility on Wallops Island, Virginia has its launchpads and buildings within a few hundred feet of the Atlantic Ocean. Both locations have resorted to replenishing the beaches with sand as a natural barrier to the sea.
Native vegetation is planted to help hold the sand in place, but it needs to be replenished every few years.
At the Langley Research Center in Hampton, Virginia, instead of building up the ground, we’re hardening buildings and moving operations to less flood-prone elevations. The center is bounded by two rivers and the Chesapeake Bay.
The effects of sea level rise extend far beyond flooding during high tides. Higher seas can drive larger and more intense storm surges – the waves of water brought by tropical storms.
In 2017, Hurricane Harvey brought flooding to the astronaut training facility at Johnson Space Center in Houston, Texas. Now we have installed flood resistant doors, increased water intake systems, and raised guard shacks to prevent interruptions to operations, which include astronaut training and mission control.
Our only facility that sits below sea level already is Michoud Assembly Facility in New Orleans. Onsite pumping systems protected the 43-acre building, which has housed Saturn rockets and the Space Launch System, from Hurricane Katrina. Since then, we’ve reinforced the pumping system so it can now handle double the water capacity.
Ames Research Center in Silicon Valley is going one step farther and gradually relocating farther south and to several feet higher in elevation to avoid the rising waters of the San Francisco Bay.
Understanding how fast and where seas will rise is crucial to adapting our lives to our changing planet.
We have a long-standing history of tracking sea level rise, through satellites like the TOPEX-Poseidon and the Jason series, working alongside partner agencies from the United States and other countries.
We just launched the Sentinel-6 Michael Freilich satellite—a U.S.-European partnership—which will use electromagnetic signals bouncing off Earth’s surface to make some of the most accurate measurements of sea levels to date.

Black Holes: Seeing the Invisible!
Black holes are some of the most bizarre and fascinating objects in the cosmos. Astronomers want to study lots of them, but there’s one big problem – black holes are invisible! Since they don’t emit any light, it’s pretty tough to find them lurking in the inky void of space. Fortunately there are a few different ways we can “see” black holes indirectly by watching how they affect their surroundings.
Speedy stars
If you’ve spent some time stargazing, you know what a calm, peaceful place our universe can be. But did you know that a monster is hiding right in the heart of our Milky Way galaxy? Astronomers noticed stars zipping superfast around something we can’t see at the center of the galaxy, about 10 million miles per hour! The stars must be circling a supermassive black hole. No other object would have strong enough gravity to keep them from flying off into space.
Two astrophysicists won half of the Nobel Prize in Physics last year for revealing this dark secret. The black hole is truly monstrous, weighing about four million times as much as our Sun! And it seems our home galaxy is no exception – our Hubble Space Telescope has revealed that the hubs of most galaxies contain supermassive black holes.
Shadowy silhouettes
Technology has advanced enough that we’ve been able to spot one of these supermassive black holes in a nearby galaxy. In 2019, astronomers took the first-ever picture of a black hole in a galaxy called M87, which is about 55 million light-years away. They used an international network of radio telescopes called the Event Horizon Telescope.
In the image, we can see some light from hot gas surrounding a dark shape. While we still can’t see the black hole itself, we can see the “shadow” it casts on the bright backdrop.
Shattered stars
Black holes can come in a smaller variety, too. When a massive star runs out of the fuel it uses to shine, it collapses in on itself. These lightweight or “stellar-mass” black holes are only about 5-20 times as massive as the Sun. They’re scattered throughout the galaxy in the same places where we find stars, since that’s how they began their lives. Some of them started out with a companion star, and so far that’s been our best clue to find them.
Some black holes steal material from their companion star. As the material falls onto the black hole, it gets superhot and lights up in X-rays. The first confirmed black hole astronomers discovered, called Cygnus X-1, was found this way.
If a star comes too close to a supermassive black hole, the effect is even more dramatic! Instead of just siphoning material from the star like a smaller black hole would do, a supermassive black hole will completely tear the star apart into a stream of gas. This is called a tidal disruption event.
Making waves
But what if two companion stars both turn into black holes? They may eventually collide with each other to form a larger black hole, sending ripples through space-time – the fabric of the cosmos!
These ripples, called gravitational waves, travel across space at the speed of light. The waves that reach us are extremely weak because space-time is really stiff.
Three scientists received the 2017 Nobel Prize in Physics for using LIGO to observe gravitational waves that were sent out from colliding stellar-mass black holes. Though gravitational waves are hard to detect, they offer a way to find black holes without having to see any light.
We’re teaming up with the European Space Agency for a mission called LISA, which stands for Laser Interferometer Space Antenna. When it launches in the 2030s, it will detect gravitational waves from merging supermassive black holes – a likely sign of colliding galaxies!
Rogue black holes
So we have a few ways to find black holes by seeing stuff that’s close to them. But astronomers think there could be 100 million black holes roaming the galaxy solo. Fortunately, our Nancy Grace Roman Space Telescope will provide a way to “see” these isolated black holes, too.
Roman will find solitary black holes when they pass in front of more distant stars from our vantage point. The black hole’s gravity will warp the starlight in ways that reveal its presence. In some cases we can figure out a black hole’s mass and distance this way, and even estimate how fast it’s moving through the galaxy.
