5 Reasons our Space Launch System is the Backbone for Deep Space Exploration

Our Space Launch System (SLS) will be the world’s most powerful rocket, engineered to carry astronauts and cargo farther and faster than any rocket ever built. Here are five reasons it is the backbone of bold, deep space exploration missions.

5. We’re Building This Rocket to Take Humans to the Moon and Beyond

The SLS rocket is a national asset for leading new missions to deep space. More than 1,000 large and small companies in 44 states are building the rocket that will take humans to the Moon. Work on SLS has an economic impact of $5.7 billion and generates 32,000 jobs. Small businesses across the U.S. supply 40 percent of the raw materials for the rocket. An investment in SLS is an investment in human spaceflight and in American industry and will lead to applications beyond NASA.

4. This Rocket is Built for Humans

Modern deep space systems are designed and built to keep humans safe from launch to landing.  SLS provides the power to safely send the Orion spacecraft and astronauts to the Moon. Orion, powered by the European Service Module, keeps the crew safe during the mission. Exploration Ground Systems at NASA’s Kennedy Space Center in Florida, safely launches the SLS with Orion on top and recovers the astronauts and Orion after splashdown.

3. This Rocket is Engineered for a Variety of Exploration Missions

SLS is engineered for decades of human space exploration to come. SLS is not just one rocket but a transportation system that evolves to meet the needs of a variety of missions. The rocket can send more than 26 metric tons (57,000 pounds) to the Moon and can evolve to send up to 45 metric tons (99,000 pounds) to the Moon. NASA has the expertise to meet the challenges of designing and building a new, complex rocket that evolves over time while developing our nation’s capability to extend human existence into deep space.

2. This Rocket can Carry Crews and Cargos Farther, Faster

SLS’s versatile design enables it to carry astronauts their supplies as well as cargo for resupply and send science missions far in the solar system. With its power and unprecedented ability to transport heavy and large volume science payloads in a single mission, SLS can send cargos to Mars or probes even farther out in the solar system, such as to Jupiter’s moon Europa, faster than any other rocket flying today. The rocket’s large cargo volume makes it possible to design planetary probes, telescopes and other scientific instruments with fewer complex mechanical parts.

1. This Rocket Complements International and Commercial Partners

The Space Launch System is the right rocket to enable exploration on and around the Moon and even longer missions away from home. SLS makes it possible for astronauts to bring along supplies and equipment needed to explore, such as pieces of the Gateway, which will be the cornerstone of sustainable lunar exploration. SLS’s ability to launch both people and payloads to deep space in a single mission makes space travel safer and more efficient. With no buildings, hardware or grocery stores on the Moon or Mars, there are plenty of opportunities for support by other rockets. SLS and contributions by international and commercial partners will make it possible to return to the Moon and create a springboard for exploration of other areas in the solar system where we can discover and expand knowledge for the benefit of humanity.

Moonbound: One Year Since Artemis I

On this day last year, the Artemis I rocket and spacecraft lit up the sky and embarked on the revolutionary mission to the Moon and back. The first integrated flight test of the rocket and spacecraft continued for 25.5 days, validating NASA’s deep exploration systems and setting the stage for humanity’s return to the lunar surface.

On Nov. 16, 2022, the Space Launch System (SLS) rocket met or exceeded all expectations during its debut launch on Artemis I. The twin solid rocket booster motors responsible for producing more than 7 million pounds of thrust at liftoff reached their performance target, helping SLS and the Orion spacecraft reach a speed of about 4,000 mph in just over two minutes before the boosters separated.

Quite a few payloads caught a ride aboard the Orion spacecraft on the Artemis I mission: In addition to a number of small scientific satellites called CubeSats, a manikin named Commander Moonikin Campos sat in the commander’s seat. A Snoopy doll served as a zero-gravity indicator — something that floats inside the spacecraft to demonstrate microgravity. 

During the mission, Orion performed two lunar flybys, coming within 80 miles of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles from our home planet, more than 1,000 times farther than where the International Space Station orbits Earth. This surpassed the record for distance traveled by a spacecraft designed to carry humans, previously set during Apollo 13.

The Orion spacecraft arrived back home to planet Earth on Dec. 11, 2022. During re-entry, Orion endured temperatures about half as hot as the surface of the Sun at about 5,000 degrees Fahrenheit. Within about 20 minutes, Orion slowed from nearly 25,000 mph to about 20 mph for its parachute-assisted splashdown. 

Recovery teams successfully retrieved the spacecraft and delivered it back to NASA’s Kennedy Space Center for de-servicing operations, which included removing the payloads (like Snoopy and Commander Moonikin Campos) and analyzing the heat shield.  

With the Artemis I mission under our belt, we look ahead to Artemis II — our first crewed mission to the Moon in over 50 years. Four astronauts will fly around the Moon inside Orion, practicing piloting the spacecraft and validating the spacecraft’s life support systems. The Artemis II crew includes: NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA astronaut Jeremy Hansen. 

As we look ahead to Artemis II, we build upon the incredible success of the Artemis I mission and recognize the hard work and achievements of the entire Artemis team. Go Artemis!

What Astronauts in Space Eat in a Day

There was a time when even NASA didn’t know if humans could eat in the microgravity environment of space. Thankfully for the future of long-term crewed missions, John Glenn proved that it was indeed possible when he ate applesauce from an aluminum tube while orbiting the Earth in 1962.

Since then, the research conducted at our Space Food Systems Laboratory at Johnson Space Center has resulted in improved taste, variety and packaging of foods intended for space travel. Current-day astronauts are now given a standard menu of over 200 approved food and drink items months before launch, allowing them to plan their daily meals far in advance.

So, with such a variety of foods to choose from, what does the typical astronaut eat in a day?  Here is an example from the International Space Station standard menu:

Sounds tasty, right?

However, these are only suggestions for astronauts, so they still have some choice over what they ultimately eat. Many astronauts, including Tim Kopra, combine different ingredients for meals.

Others plan to eat special foods for the holidays. Astronauts Scott Kelly and Kjell Lindgren did just that on Thanksgiving last year when they ate smoked turkey, candied yams, corn and potatoes au gratin.

Another key factor that influences what astronauts eat is the availability of fresh fruits and vegetables, which are delivered via resupply spacecrafts.  When these foods arrive to the space station, they must be eaten quickly before they spoil. Astronaut Tim Peake doesn’t seem to mind.

Nutrition is important to help counteract some of the effects spaceflight have on the body, such as bone and muscle loss, cardiovascular degradation, impairment of immune function, neurovestibular changes and vision changes. 

“Nutrition is vital to the mission,” Scott M. Smith, Ph.D., manager for NASA’s Nutritional Biochemistry Lab said. “Without proper nutrition for the astronauts, the mission will fail. It’s that simple.”

We work hard to help astronauts feel less homesick by providing them with food that not only reminds them of life back on Earth, but is also nutritious and healthy. 

Here are some unusual space food inventions that are no longer in use:

Gelatin-coated sandwich and cookie cubes

Compressed bacon squares

Freeze dried ice cream

The Big Build: Artemis I Stacks Up

Our Space Launch System (SLS) rocket is coming together at the agency’s Kennedy Space Center in Florida this summer. Our mighty SLS rocket is set to power the Artemis I mission to send our Orion spacecraft around the Moon. But, before it heads to the Moon, NASA puts it together right here on Earth.

Read on for more on how our Moon rocket for Artemis I will come together this summer:

Get the Base

How do crews assemble a rocket and spacecraft as tall as a skyscraper? The process all starts inside the iconic Vehicle Assembly Building at Kennedy with the mobile launcher. Recognized as a Florida Space Coast landmark, the Vehicle Assembly Building, or VAB, houses special cranes, lifts, and equipment to move and connect the spaceflight hardware together. Orion and all five of the major parts of the Artemis I rocket are already at Kennedy in preparation for launch. Inside the VAB, teams carefully stack and connect the elements to the mobile launcher, which serves as a platform for assembly and, later, for fueling and launching the rocket.

Start with the boosters

Because they carry the entire weight of the rocket and spacecraft, the twin solid rocket boosters for our SLS rocket are the first elements to be stacked on the mobile launcher inside the VAB. Crews with NASA’s Exploration Ground Systems and contractor Jacobs team completed stacking the boosters in March. Each taller than the Statue of Liberty and adorned with the iconic NASA “worm” logo, the five-segment boosters flank either side of the rocket’s core stage and upper stage. At launch, each booster produces more than 3.6 million pounds of thrust in just two minutes to quickly lift the rocket and spacecraft off the pad and to space.

Bring in the core stage

In between the twin solid rocket boosters is the core stage. The stage has two huge liquid propellant tanks, computers that control the rocket’s flight, and four RS-25 engines. Weighing more than 188,000 pounds without fuel and standing 212 feet, the core stage is the largest element of the SLS rocket. To place the core stage in between the two boosters, teams will use a heavy-lift crane to raise and lower the stage into place on the mobile launcher.

On launch day, the core stage’s RS-25 engines produce more than 2 million pounds of thrust and ignite just before the boosters. Together, the boosters and engines produce 8.8 million pounds of thrust to send the SLS and Orion into orbit.

Add the Launch Vehicle Stage Adapter

Once the boosters and core stage are secured, teams add the launch vehicle stage adapter, or LVSA, to the stack. The LVSA is a cone-shaped element that connects the rocket’s core stage and Interim Cryogenic Propulsion Stage (ICPS), or upper stage. The roughly 30-foot LVSA houses and protects the RL10 engine that powers the ICPS. Once teams bolt the LVSA into place on top of the rocket, the diameter of SLS will officially change from a wide base to a more narrow point — much like a change in the shape of a pencil from eraser to point.

Lower the Interim Cryogenic Propulsion Stage into place

Next in the stacking line-up is the Interim Cryogenic Propulsion Stage or ICPS. Like the LVSA, crews will lift and bolt the ICPS into place. To help power our deep space missions and goals, our SLS rocket delivers propulsion in phases. At liftoff, the core stage and solid rocket boosters will propel Artemis I off the launch pad. Once in orbit, the ICPS and its single RL10 engine will provide nearly 25,000 pounds of thrust to send our Orion spacecraft on a precise trajectory to the Moon.

Nearly there with the Orion stage adapter

When the Orion stage adapter crowns the top of the ICPS, you’ll know we’re nearly complete with stacking SLS rocket for Artemis I. The Orion Stage Adapter is more than just a connection point. At five feet in height, the Orion stage adapter may be small, but it holds and carries several small satellites called CubeSats. After Orion separates from the SLS rocket and heads to the Moon, these shoebox-sized payloads are released into space for their own missions to conduct science and technology research vital to deep space exploration. Compared to the rest of the rocket and spacecraft, the Orion stage adapter is the smallest SLS component that’s stacked for Artemis I.

Top it off

Finally, our Orion spacecraft will be placed on top of our Moon rocket inside the VAB. The final piece will be easy to spot as teams recently added the bright red NASA “worm” logotype to the outside of the spacecraft. The Orion spacecraft is much more than just a capsule built to carry crew. It has a launch abort system, which will carry the crew to safety in case of an emergency, and a service module developed by the European Space Agency that will power and propel the spacecraft during its three-week mission. On the uncrewed Artemis I mission, Orion will check out the spacecraft’s critical systems, including navigation, communications systems, and the heat shield needed to support astronauts who will fly on Artemis II and beyond.

Ready for launch!

The path to the pad requires many steps and check lists. Before Artemis I rolls to the launch pad, teams will finalize outfitting and other important assembly work inside the VAB. Once assembled, the integrated SLS rocket and Orion will undergo several final tests and checkouts in the VAB and on the launch pad before it’s readied for launch.

The Artemis I mission is the first in a series of increasingly complex missions that will pave the way for landing the first woman and the first person of color on the Moon. The Space Launch System is the only rocket that can send NASA astronauts aboard NASA’s Orion spacecraft and supplies to the Moon in a single mission.

Who is the First Woman? Meet our new graphic novel hero!

Artemis is the first step in the next era of human exploration. This time when we go to the Moon, we're staying, to study and learn more than ever before. We’ll test new technologies and prepare for our next giant leap – sending astronauts to Mars.

Artemis missions will achieve many historic feats, like landing the first woman and first person of color on the Moon.

With today’s release of our graphic novel First Woman: NASA’s Promise for Humanity you don’t have to wait to join us on an inspiring adventure in space.

Meet Commander Callie Rodriguez, the first woman to explore the Moon – at least in the comic book universe.

In Issue No. 1: Dream to Reality, Callie, her robot sidekick RT, and a team of other astronauts are living and working on the Moon in the not-too-distant future. Like any good, inquisitive robot, RT asks Callie how he came to be – not just on the Moon after a harrowing experience stowed in the Orion capsule – but about their origin story, if you will.

From her childhood aspirations of space travel to being selected as an astronaut candidate, Callie takes us on her trailblazing journey to the Moon.

As they venture out to check on a problem at a lunar crater, Callie shares with RT and the crew that she was captivated by space as a kid, and how time in her father’s autobody shop piqued her interest in building things and going places.

Callie learned at a young age that knowledge is gained through both success and failure in the classroom and on the field.

Through disappointment, setbacks, and personal tragedy, Callie pursues her passions and eventually achieves her lifelong dream of becoming an astronaut – a road inspired by the real lives of many NASA astronauts living and working in space today.

So what's up with that lunar crater?

Did Callie pass her math class?

And where did RT come from?

Celebrating Five Years at Jupiter!

We just released new eye-catching posters and backgrounds to celebrate the five-year anniversary of Juno’s orbit insertion at Jupiter in psychedelic style.

On July 4, 2016, our Juno spacecraft arrived at Jupiter on a mission to peer through the gas giant planet’s dense clouds and answer questions about the origins of our solar system. Since its arrival, Juno has provided scientists a treasure trove of data about the planet’s origins, interior structures, atmosphere, and magnetosphere.

Juno is the first mission to observe Jupiter’s deep atmosphere and interior, and will continue to delight with dazzling views of the planet’s colorful clouds and Galilean moons. As it circles Jupiter, Juno provides critical knowledge for understanding the formation of our own solar system, the Jovian system, and the role giant planets play in putting together planetary systems elsewhere.

Get the posters and backgrounds here!

Solar System: Things to Know This Week

Go for Venus! Fifty-five years ago this week, Mariner 2, the first fully successful mission to explore another planet launched from Cape Canaveral in Florida. Here are 10 things to know about Mariner 2.

1. Interplanetary Cruise 

On August 27, 1962, Mariner 2 launched on a three and a half month journey to Venus. The little spacecraft flew within 22,000 miles (about 35,000 kilometers) of the planet. 

2. Quick Study 

Mariner 2's scan of Venus lasted only 42 minutes. And, like most of our visits to new places, the mission rewrote the books on what we know about Earth's sister planet.

3. Hot Planet 

The spacecraft showed that surface temperature on Venus was hot enough to melt lead: at least 797 degrees Fahrenheit (425 degrees Celsius) on both the day and night sides.

4. Continuous Clouds 

The clouds that make Venus shine so bright in Earth's skies are dozens of miles thick and permanent. It's always cloudy on Venus, and the thick clouds trap heat - contributing to a runaway "greenhouse effect."

5. Night Light 

Those clouds are why Venus shines so brightly in Earth's night sky. The clouds reflect and scatter sunlight, making Venus second only to our Moon in celestial brightness.

6. Under Pressure 

Venus' clouds also create crushing pressure. Mariner 2's scan revealed pressure on the surface of Venus is equal to pressure thousands of feet under Earth's deepest oceans.

7. Slow Turn 

Mariner 2 found Venus rotates very slowly, and in the opposite direction of most planets in our solar system.

8. Space Travel Is Tough 

Mariner 2 was a remarkable accomplishment, considering that in 1962 engineers were still in the very early stages of figuring out how operate spacecraft beyond Earth orbit. The first five interplanetary missions launched - by the U.S. and Soviet Union, the only two spacefaring nations at the time - were unsuccessful.

9. Not Ready for Its Close Up 

Mariner 2 carried no cameras. The first close-up pictures of Venus came from NASA's Mariner 10 in 1974.  

10. Hot Shot 

The first (and still incredibly rare) photo of the surface of Venus was taken by the Soviet Venera 9 lander, which survived for a little more than a minute under the crushing pressure and intense heat on the ground.
