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.
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.
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.
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.
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.
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.

Meet at midnight to have a planetary party when Jupiter and Saturn are visible at the same time!
The best time will be after midnight on June 17. To see the best details, you’ll need a telescope.
Saturn will be at opposition on June 15, when Saturn, the Earth and the sun are in a straight line.
Opposition provides the best views of Saturn and several of its brightest moons. At the very least, you should be able to see Saturn’s moon Titan, which is larger and brighter than Earth’s moon.
As mentioned earlier, you’ll be able to see Jupiter and Saturn in the night sky this month. Through a telescope, you’ll be able to see the cloud bands on both planets. Saturn’s cloud bands are fainter than those on Jupiter.
You’ll also have a great view of Saturn’s Cassini Division, discovered by astronomer Giovanni Cassini in 1675, namesake of our Cassini spacecraft.
Our Cassini spacecraft has been orbiting the planet since 2004 and is on a trajectory that will ultimately plunge it into Saturn’s atmosphere on September 15, 2017, bringing the mission to a close.
Our Juno spacecraft recently completed its sixth Jupiter flyby. Using only binoculars you can observe Jupiter’s 4 Galilean moons - Io, Callisto, Ganymede and Europa.

Hello! When preparing for a mission what are your primary concerns for the astronauts safety- what do you focus on with the most intensity to feel confident in sending a crew up?
“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.” - Neil Armstrong, Apollo 11
Voyager famously captured two unique views of our homeworld from afar. One image, taken in 1977 from a distance of 7.3 million miles (11.7 million kilometers) (above), showed the full Earth and full Moon in a single frame for the first time in history. The second (below), taken in 1990 as part of a “family portrait of our solar system from 4 billion miles (6.4 billion kilometers), shows Earth as a tiny blue speck in a ray of sunlight.” This is the famous “Pale Blue Dot” image immortalized by Carl Sagan.
“This was our willingness to see the Earth as a one-pixel object in a far greater cosmos,” Sagan’s widow, Ann Druyan said of the image. “It's that humility that science gives us. That weans us from our childhood need to be the center of things. And Voyager gave us that image of the Earth that is so heart tugging because you can't look at that image and not think of how fragile, how fragile our world is. How much we have in common with everyone with whom we share it; our relationship, our relatedness, to everyone on this tiny pixel."
Our Kepler mission captured Earth’s image as it slipped past at a distance of 94 million miles (151 million kilometers). The reflection was so extraordinarily bright that it created a saber-like saturation bleed across the instrument’s sensors, obscuring the neighboring Moon.
This beautiful shot of Earth as a dot beneath Saturn’s rings was taken in 2013 as thousands of humans on Earth waved at the exact moment the spacecraft pointed its cameras at our home world. Then, in 2017, Cassini caught this final view of Earth between Saturn’s rings as the spacecraft spiraled in for its Grand Finale at Saturn.
"The image is simply stunning. The image of the Earth evokes the famous 'Blue Marble' image taken by astronaut Harrison Schmitt during Apollo 17...which also showed Africa prominently in the picture." -Noah Petro, Deputy Project Scientist for our Lunar Reconnaissance Orbiter mission.
As part of an engineering test, our OSIRIS-REx spacecraft captured this image of Earth and the Moon in January 2018 from a distance of 39.5 million miles (63.6 million kilometers). When the camera acquired the image, the spacecraft was moving away from our home planet at a speed of 19,000 miles per hour (8.5 kilometers per second). Earth is the largest, brightest spot in the center of the image, with the smaller, dimmer Moon appearing to the right. Several constellations are also visible in the surrounding space.
A human observer with normal vision, standing on Mars, could easily see Earth and the Moon as two distinct, bright "evening stars."
"This image from the Deep Space Climate Observatory (DSCOVR) satellite captured a unique view of the Moon as it moved in front of the sunlit side of Earth in 2015. It provides a view of the far side of the Moon, which is never directly visible to us here on Earth. “I found this perspective profoundly moving and only through our satellite views could this have been shared.” - Michael Freilich, Director of our Earth Science Division.
Eight days after its final encounter with Earth—the second of two gravitational assists from Earth that helped boost the spacecraft to Jupiter—the Galileo spacecraft looked back and captured this remarkable view of our planet and its Moon. The image was taken from a distance of about 3.9 million miles (6.2 million kilometers).
Earth from about 393,000 miles (633,000 kilometers) away, as seen by the European Space Agency’s comet-bound Rosetta spacecraft during its third and final swingby of our home planet in 2009.
The Mercury-bound MESSENGER spacecraft captured several stunning images of Earth during a gravity assist swingby of our home planet on Aug. 2, 2005.
Our home planet is a beautiful, dynamic place. Our view from Earth orbit sees a planet at change. Check out more images of our beautiful Earth here.
We pioneer and supports an amazing range of advanced technologies and tools to help scientists and environmental specialists better understand and protect our home planet - from space lasers to virtual reality, small satellites and smartphone apps.
To celebrate Earth Day 2018, April 22, we are highlighting many of these innovative technologies and the amazing applications behind them.

#TBT to 1989 when Voyager 2 spotted Uranus looking like a seemingly perfect robin’s egg. 💙 When our Voyager 2 spacecraft flew by it in this image, one pole was pointing directly at the Sun. This means that no matter how much it spins, one half is completely in the sun at all times, and the other half is in total darkness.. Far-flung, Uranus – an ice giant of our solar system – is as mysterious as it is distant. Soon after its launch in 2021, our James Webb Space Telescope will change that by unlocking secrets of its atmosphere. Image Credit: NASA/JPL-Caltech

How has being in space changed your perspective of life on Earth?
On Wednesday, Oct. 28 and Friday, Nov. 6, Commander Scott Kelly and Flight Engineer Kjell Lindgren will perform spacewalks in support of space station assembly and maintenance. You can watch both of these events live on NASA Television. But, before you do, here are 7 things to know:
1. What’s the Point of a Spacewalk?
Spacewalks are important events where crew members repair, maintain and upgrade parts of the International Space Station. Spacewalks can also be referred to as an EVA – Extravehicular Activity. On Wednesday, Oct. 28, Commander Scott Kelly and Flight Engineer Kjell Lindgren will complete a spacewalk. During this time they will service the Canadarm2 robotic arm, route cables for a future docking port, and place a thermal cover over a dark matter detection experiment, which is a state-of-the-art particles physics detector that has been attached to the station since 2011.
2. What Do They Wear?
The Extravehicular Mobility Unit (EMU) spacewalking suit weighs around 350 pounds. It’s weightless in space, but mass is still very real. The EMU provides a crew member with life support and an enclosure that enables them to work outside the space station. The suit provides atmospheric containment, thermal insulation, cooling, solar radiation protection and micrometeoroid/orbital debris protection.
3. How Long Are Spacewalks?
Spacewalks typically last around 6 1/2 hours, but can be extended to 7 or 8 hours, if necessary. The timeline is designed to accommodate as many tasks as possible, as spacewalks require an enormous amount of work to prepare.
4. What About Eating and Drinking?
Before a spacewalk astronauts eat light, usually something like a protein bar. The spacesuits also have a drink bag inside, and there is a bite valve that allows ready access to water.
5. What About Communication?
Spacewalkers wear a ‘comm’ cap that allows them to constantly communicate with astronauts inside the space station that are helping with the walk, and with mission control. Astronauts also wear a checklist on their left wrist called a “cuff checklist”. This list contains emergency procedures.
6. What About Light?
Something that most people don’t realize about spacewalks is that the crew will experience a sunrise/sunset every 45 minutes. Luckily, their spacesuits are equipped with lights that allow them to see in times of darkness.
7. How Do They Stay Safe?
When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft. One end of the tether is hooked to the spacewalker, while the other end is connected to the vehicle. Another way astronauts stay safe is by wearing a SAFER, which is a Simplified Aid for EVA Rescue. This device is worn like a backpack and uses small jet thrusters to let an astronaut move around in space.
You can watch both of the upcoming spacewalks live on: NASA Television or the NASA App, or follow along on @Space_Station Twitter.
Wednesday, Oct. 28: Coverage begins at 6:30 a.m. EDT. Spacewalk begins at 8:10 a.m.
Friday, Nov. 6: Coverage begins at 5:45 a.m. EDT. Spacewalk begins at 7:15 a.m.

Is earth doing fine, I'm afraid of all the bad stuff that's happening. I just wanna know if it's doing okay (◍•﹏•)
Are you hoping to get to the gym more often in 2016? While you work out on Earth, here are a few ways that astronauts stay fit on the International Space Station.
Exercise is an important part of the daily routine for astronauts aboard the International Space Station to prevent bone and muscle loss, and to maintain cardiovascular health. On average, astronauts exercise two hours per day. The equipment they use in space is different than what we use on Earth.
Lifting 200 pounds on Earth may be a lot of work, but in microgravity a 200 pound dumbbell would not weigh anything. Therefore, free weights do not serve as a good strength training tool for the astronauts in space. That means exercise equipment needs to be specifically designed for use in space so astronauts will receive the workout needed.
Advanced Resistive Exercise Device (ARED)
The ARED hardware uses adjustable resistance piston-driven vacuum cylinders along with a flywheel system to simulate free-weight exercises in normal gravity. It’s primary goal is to maintain muscle strength and bone mass in astronauts during long periods in space.
Cycle Ergometer with Vibration Isolation System (CEVIS)
CEVIS is very similar to a mechanical bicycle. It’s bolted to the floor, and astronauts snap their shoes on to the pedals. A seat belt can be used to hold them in position, and they can change the resistance for varying levels of difficulty.
Russian Treadmill (BD-2)
BD-2 is the treadmill that is found in the Russian segment of the space station. It allows crew members to walk and run with a speed from 2.4 to 20 km/hr.
Combined Operational Load Bearing External Resistance Treadmill (COLBERT)
COLBERT is the second generation U.S. treadmill on the space station. It features data collection devices that will allow scientists and doctors to evaluate how effective the exercise is in reducing the amount of bone and muscle density loss due to microgravity exposure. It allows crew members to walk and run with a speed from 4.8 to 20 km/hr.
Why is it called COLBERT?
The treadmill’s name was selected after comedian Stephen Colbert took interest in our online naming poll for Node 3 of space station. He urged his viewers to submit the name “Colbert.” Although we ended up choosing the suggested name “Tranquillity” for the node, we designated its new treadmill “COLBERT” in honor of the name that received the most entries.
VELO Ergomoeter Bike (VB-3)
VB-3 is used for aerobic training, medical tests and pedaling regimes. It is located in the Russian segment of the space station.

Ginger Kerrick will be taking your questions in an Answer Time session on Friday, September 27 from 12pm - 1 pm ET here on NASA’s Tumblr! Ginger served as a Flight Director in Mission Control for 11 years and is now the Flight Integration Division Chief at Johnson Space Center. Find out what it’s like to send humans to space and learn more about her position as our first female Hispanic flight director. Make sure to ask your question now by visiting http://nasa.tumblr.com/ask!
Ginger Kerrick, as a child, dreamed of growing up to be either a basketball player or an astronaut. When neither dream came to fruition, Kerrick developed a fresh perspective – best summed up by the phrase “It just wasn’t meant to be” – and later became part of our team, serving in the Mission Control Center at the NASA Johnson Space Center as a Flight Director who has, to date, supported 13 International Space Station and five joint space shuttle missions. It was there that Kerrick, a few years earlier, became the first non-astronaut Capsule Communicator (CapCom), the flight controller that speaks directly to the astronaut crew in space, on behalf of the rest of the Mission Control team.
Today, Ginger Kerrick is the Flight Integration Division Chief at our Johnson Space Center. Her department is responsible for crew safety and training, among a list of other duties. She has worked for NASA since 1994, and interned here while she was earning a bachelor’s degree in physics from Texas Tech University. She also has a master’s degree in physics from the university.

Some of the earliest human explorers used mechanical tools called sextants to navigate vast oceans and discover new lands. Today, high-tech tools navigate microscopic DNA to discover previously unidentified organisms. Scientists aboard the International Space Station soon will have both types of tools at their disposal.
Orbital ATK’s Cygnus spacecraft is scheduled to launch its ninth contracted cargo resupply mission to the space station no earlier than May 21. Sending crucial science, supplies and cargo to the crew of six humans living and working on the orbiting laboratory.
Our Gemini missions conducted the first sextant sightings from a spacecraft, and designers built a sextant into Apollo vehicles as a lost-communications navigation backup. The Sextant Navigation investigation tests use of a hand-held sextant for emergency navigation on missions in deep space as humans begin to travel farther from Earth.
Jim Lovell (far left) demonstrated on Apollo 8 that sextant navigation could return a space vehicle home.
The remoteness and constrained resources of living in space require simple but effective processes and procedures to monitor the presence of microbial life, some of which might be harmful. Biomolecule Extraction and Sequencing Technology (BEST) advances the use of sequencing processes to identify microbes aboard the space station that current methods cannot detect and to assess mutations in the microbial genome that may be due to spaceflight.
Genes in Space 3 performed in-flight identification of bacteria on the station for the first time. BEST takes that one step farther, identifying unknown microbial organisms using a process that sequences directly from a sample with minimal preparation, rather than with the traditional technique that requires growing a culture from the sample.
Adding these new processes to the proven technology opens new avenues for inflight research, such as how microorganisms on the station change or adapt to spaceflight.
The investigation’s sequencing components provide important information on the station’s microbial occupants, including which organisms are present and how they respond to the spaceflight environment -- insight that could help protect humans during future space exploration. Knowledge gained from BEST could also provide new ways to monitor the presence of microbes in remote locations on Earth.
Moving on to science at a scale even smaller than a microbe, the new Cold Atom Lab (CAL) facility could help answer some big questions in modern physics.
CAL creates a temperature ten billion (Yup. BILLION) times colder than the vacuum of space, then uses lasers and magnetic forces to slow down atoms until they are almost motionless. CAL makes it possible to observe these ultra-cold atoms for much longer in the microgravity environment on the space station than would be possible on the ground.
Results of this research could potentially lead to a number of improved technologies, including sensors, quantum computers and atomic clocks used in spacecraft navigation.
A partnership between the European Space Agency (ESA) and Space Application Services (SpaceAps), The International Commercial Experiment, or ICE Cubes Service, uses a sliding framework permanently installed on the space station and “plug-and-play” Experiment Cubes.
The Experiment Cubes are easy to install and remove, come in different sizes and can be built with commercial off-the-shelf components, significantly reducing the cost and time to develop experiments.
ICE Cubes removes barriers that limit access to space, providing more people access to flight opportunities. Potential fields of research range from pharmaceutical development to experiments on stem cells, radiation, and microbiology, fluid sciences, and more.
