More than 45 years since humans last set foot on the lunar surface, we’re going back to the Moon and getting ready for Mars. The Artemis program will send the first woman and next man to walk on the surface of the Moon by 2024, establish sustainable lunar exploration and pave the way for future missions deeper into the solar system.
Our powerful new rocket, the Space Launch System (SLS), will send astronauts aboard the Orion spacecraft a quarter million miles from Earth to lunar orbit. The spacecraft is designed to support astronauts traveling hundreds of thousands of miles from home, where getting back to Earth takes days rather hours.
Astronauts will dock Orion at our new lunar outpost that will orbit the Moon called the Gateway. This small spaceship will serve as a temporary home and office for astronauts in orbit between missions to the surface of the Moon. It will provide us and our partners access to the entire surface of the Moon, including places we’ve never been before like the lunar South Pole. Even before our first trip to Mars, astronauts will use the Gateway to train for life far away from Earth, and we will use it to practice moving a spaceship in different orbits in deep space.
The crew will board a human landing system docked to the Gateway to take expeditions down to the surface of the Moon. We have proposed using a three-stage landing system, with a transfer vehicle to take crew to low-lunar orbit, a descent element to land safely on the surface, and an ascent element to take them back to the Gateway.
Astronauts will ultimately return to Earth aboard the Orion spacecraft. Orion will enter the Earth’s atmosphere traveling at 25,000 miles per hour, will slow to 300 mph, then parachutes will deploy to slow the spacecraft to approximately 20 mph before splashing down in the Pacific Ocean.
We will establish sustainable lunar exploration within the next decade, and from there, we will prepare for our next giant leap – sending astronauts to Mars!

On November 14, NASA is set to launch the uncrewed Artemis I flight test to the Moon and back. Artemis I is the first integrated flight test of the Space Launch System (SLS) rocket, the Orion spacecraft, and Exploration Ground Systems at NASA’s Kennedy Space Center in Florida. These are the same systems that will bring future Artemis astronauts to the Moon.
Standing 322 feet (98 meters) tall, the SLS rocket comprises of a core stage, an upper stage, two solid boosters, and four RS-25 engines. The SLS rocket is the most powerful rocket in the world, able to carry 59,500 pounds (27 metric tons) of payloads to deep space — more than any other vehicle. With its unprecedented power, SLS is the only rocket that can send the Orion spacecraft, astronauts, and cargo directly to the Moon on a single mission.
Before launch, Artemis I has some big help: the Vehicle Assembly Building (VAB) at KSC is the largest single-story building in the world. The VAB was constructed for the assembly of the Apollo/Saturn V Moon rocket, and this is where the SLS rocket is assembled, maintained, and integrated with the Orion spacecraft.
The mobile launcher is used to assemble, process, and launch the SLS rocket and Orion spacecraft. The massive structure consists of a two-story base and a tower equipped with a number of connection lines to provide the rocket and spacecraft with power, communications, coolant, and fuel prior to launch.
Capable of carrying 18 million pounds (8.2 million kg) and the size of a baseball infield, crawler-transporter 2 will transport SLS and Orion the 4.2 miles (6.8 km) to Launch Pad 39B. This historic launch pad was where the Apollo 10 mission lifted off from on May 18, 1969, to rehearse the first Moon landing.
During the launch, SLS will generate around 8.8 million pounds (~4.0 million kg) of thrust, propelling the Orion spacecraft into Earth’s orbit. Then, Orion will perform a Trans Lunar Injection to begin the path to the Moon. The spacecraft will orbit the Moon, traveling 40,000 miles beyond the far side of the Moon — farther than any human-rated spacecraft has ever flown.
The Orion spacecraft is designed to carry astronauts on deep space missions farther than ever before. Orion contains the habitable volume of about two minivans, enough living space for four people for up to 21 days. Future astronauts will be able to prepare food, exercise, and yes, have a bathroom. Orion also has a launch abort system to keep astronauts safe if an emergency happens during launch, and a European-built service module that fuels and propels the spacecraft.
While the Artemis I flight test is uncrewed, the Orion spacecraft will not be empty: there will be three manikins aboard the vehicle. Commander Moonikin Campos will be sitting in the commander’s seat, collecting data on the vibrations and accelerations future astronauts will experience on the journey to the Moon. He is joined with two phantom torsos, Helga and Zohar, in a partnership with the German Aerospace Center and Israeli Space Agency to test a radiation protection vest.
A host of shoebox-sized satellites called CubeSats help enable science and technology experiments that could enhance our understanding of deep space travel and the Moon while providing critical information for future Artemis missions.
At the end of the four-week mission, the Orion spacecraft will return to Earth. Orion will travel at 25,000 mph (40,000 km per hour) before slowing down to 300 mph (480 km per hour) once it enters the Earth’s atmosphere. After the parachutes deploy, the spacecraft will glide in at approximately 20 mph (32 km per hour) before splashdown about 60 miles (100 km) off the coast of California. NASA’s recovery team and the U.S. Navy will retrieve the Orion spacecraft from the Pacific Ocean.
With the ultimate goal of establishing a long-term presence on the Moon, Artemis I is a critical step as NASA prepares to send humans to Mars and beyond.

It will take incredible power to send the first woman and the next man to the Moon’s South Pole by 2024. That’s where America’s Space Launch System (SLS) rocket comes in to play.
Providing more payload mass, volume capability and energy to speed missions through deep space than any other rocket, our SLS rocket, along with our lunar Gateway and Orion spacecraft, creates the backbone for our deep space exploration and Artemis lunar mission goals.
Here’s why our SLS rocket is a deep space rocket like no other:
The Artemis missions will send humans 280,000 miles away from Earth. That’s 1,000 times farther into space than the International Space Station. To accomplish that mega feat, you need a rocket that’s designed to lift — and lift heavy. With help from a dynamic core stage — the largest stage we have ever built — the 5.75-million-pound SLS rocket can propel itself off the Earth. This includes the 57,000 pounds of cargo that will go to the Moon. To accomplish this, SLS will produce 15% more thrust at launch and during ascent than the Saturn V did for the Apollo Program.
Where do our rocket’s lift and thrust capabilities come from? If you take a peek under our powerful rocket’s hood, so to speak, you’ll find a core stage with four RS-25 engines that produce more than 2 million pounds of thrust alongside two solid rocket boosters that each provide another 3.6 million pounds of thrust power. It’s a bold design. Together, they provide an incredible 8.8 million pounds of thrust to power the Artemis missions off the Earth. The engines and boosters are modified heritage hardware from the Space Shuttle Program, ensuring high performance and reliability to drive our deep space missions.
While our rocket’s core stage design will remain basically the same for each of the Artemis missions, the SLS rocket’s upper stage evolves to open new possibilities for payloads and even robotic scientific missions to worlds farther away than the Moon like Mars, Saturn and Jupiter. For the first three Artemis missions, our SLS rocket uses an interim cryogenic propulsion stage with one RL10 engine to send Orion to the lunar south pole. For Artemis missions following the initial 2024 Moon landing, our SLS rocket will have an exploration upper stage with bigger fuel tanks and four RL10 engines so that Orion, up to four astronauts and larger cargoes can be sent to the Moon, too. Additional core stages and upper stages will support either crewed Artemis missions, science missions or cargo missions for a sustained presence in deep space.
Crews at our Michoud Assembly Facility in New Orleans are in the final phases of assembling the core stage for Artemis I— and are already working on assembly for Artemis II.
Through the Artemis program, we aim not just to return humans to the Moon, but to create a sustainable presence there as well. While there, astronauts will learn to use the Moon’s natural resources and harness our newfound knowledge to prepare for the horizon goal: humans on Mars.

Dozens of science experiments will soon make their red carpet debuts on the International Space Station. They will arrive courtesy of a Dragon cargo spacecraft launched from Cape Canaveral Air Force Station in Florida. The starring players include investigations into 3D printing organ tissue, breaking up rocks and building bones.
Meet some of the experiments blasting off that could lead to the development of new technologies as well as improve life on Earth.
Scientists and medical professionals have long dreamed of the day 3D printers can be used to create useable human organs. But pesky gravity seems to always get in the way.
Enter microgravity. The new BioFabrication Facility (BFF) will provide a platform to attempt the creation of this organ tissue on the space station, a potential first step towards creating entire human organs in space.
Extracting minerals from rocks doesn’t always require brute force. Microbes can be deployed for the same purpose in a process called bio-mining. While common on Earth, the method still needs to be explored in space to see if it can eventually help explorers on the Moon and Mars. The BioRock investigation will examine the interactions between microbes and rocks and see if microgravity could limit the use of bio-mining by restricting bacterial growth.
Goodyear Tire will investigate if microgravity can help improve the silica design process, silica rubber formation and tire manufacturing. This investigation could lead to improvements like better tire performance and increased fuel efficiency, putting a bit of cash back in your pocket.
Meet microglia: a type of immune defense cell found in the central nervous system. Better understanding nerve cells and their behavior in microgravity is crucial to protecting astronaut health.
The Space Tango-Induced Pluripotent Stem Cells experiment will convert induced pluripotent stem cells (iPSCs) derived from patients with Parkinson’s and Multiple Sclerosis into different types of brain cells. Researchers will examine two things:
How microglial cells grow and move
Changes in gene expression in microgravity
Studying this process in microgravity could reveal mechanisms not previously understood and could lead to improved prevention and treatments for the diseases.
Moss, the tiny plants you see covering rocks and trees in the woods, change how they behave once the gravity in their environment changes. Space Moss compares the mosses grown aboard the space station with your typical run-of-the-mill Earth-bound moss.
This investigation will let researchers see how moss behavior in space could allow it to serve as a source of food and oxygen on future Moon or Mars bases.
Docking with the space station requires physical points for connections, and International Docking Adapters (IDAs) are providing a more sophisticated way of doing so.
IDA 3 will be attached to the Harmony mode, home to two existing IDAs. This adapter can accommodate commercial crew vehicle dockings, such as the first spacecraft to launch from U.S. soil since the space shuttle.
The Cell Science-02 investigation will improve our understanding of tissue regeneration and allow us to develop better countermeasures to fight loss of bone density by astronauts.
By examining the effects of microgravity on healing agents, this investigation may be able to assist people on Earth being treated for serious wounds or osteoporosis.

After 20 years in space, the Cassini spacecraft is running out of fuel. In 2010, Cassini began a seven-year mission extension in which the plan was to expend all of the spacecraft’s propellant exploring Saturn and its moons. This led to the Grand Finale and ends with a plunge into the planet’s atmosphere at 6:32 a.m. EDT on Friday, Sept. 15.
The spacecraft will ram through Saturn’s atmosphere at four times the speed of a re-entry vehicle entering Earth’s atmosphere, and Cassini has no heat shield. So temperatures around the spacecraft will increase by 30-to-100 times per minute, and every component of the spacecraft will disintegrate over the next couple of minutes…
Cassini’s gold-colored multi-layer insulation blankets will char and break apart, and then the spacecraft's carbon fiber epoxy structures, such as the 11-foot (3-meter) wide high-gain antenna and the 30-foot (11-meter) long magnetometer boom, will weaken and break apart. Components mounted on the outside of the central body of the spacecraft will then break apart, followed by the leading face of the spacecraft itself.

Will the robot be able to send vedio footage?
Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry written by NASA astronaut Scott Tingle.

Our crew just finished the final training event before the launch. Tomorrow, at 13:20 local time (Baikonur), we will strap the Soyuz MS-07 spacecraft to our backs and fly it to low Earth orbit. We will spend 2.5 days in low Earth orbit before docking to the MRM-1 docking port on the International Space Station (ISS). There we will begin approximately 168 days of maintenance, service and science aboard one of the greatest engineering marvels that humans have ever created.
Today was bittersweet. Ending a 2-year process of intense training was welcomed by all of us. We are very tired. Seeing our families for the last time was difficult. I am pretty lucky, though. My wife, Raynette, and the kids have grown up around military service and are conditioned to endure the time spent apart during extended calls-to-duty. We are also very much anticipating the good times we will have upon my return in June. Sean and Amy showed me a few videos of them mucking it up at Red Square before flying out to Baikonur. Eric was impressed with the Russian guards marching in to relieve the watch at Red Square. Raynette was taking it all in stride and did not seem surprised by any of it. I think I might have a family of mutants who are comfortable anywhere. Nice! And, by the way, I am VERY proud of all of them!
Tomorrow’s schedule includes a wake-up at 04:00, followed by an immediate medical exam and light breakfast. Upon returning to our quarters, we will undergo a few simple medical procedures that should help make the 2.5-day journey to ISS a little more comfortable. I’ve begun prepping with motion sickness medication that should limit the nausea associated with the first phases of spaceflight. I will continue this effort through docking. This being my first flight, I’m not sure how my body will respond and am taking all precautions to maintain a good working capability. The commander will need my help operating the vehicle, and I need to not be puking into a bag during the busy times. We suit up at 09:30 and then report to the State Commission as “Готовы к Полёту”, or “Ready for Flight”. We’ll enter the bus, wave goodbye to our friends and family, and then head out to the launch pad. Approximately 2 kilometers from the launch pad, the bus will stop.
The crew will get out, pee on the bus’s tire, and then complete the last part of the drive to the launch pad. This is a traditional event first done by Yuri Gagarin during his historic first flight and repeated in his honor to this day. We will then strap in and prepare the systems for launch. Next is a waiting game of approximately 2 hours. Ouch. The crew provided five songs each to help pass the time. My playlist included “Born to Run” (Springsteen), “Sweet Child O’ Mine” (Guns and Roses), “Cliffs of Dover” (Eric Johnson), “More than a Feeling” (Boston), and “Touch the Sky” (Rainbow Bridge, Russian). Launch will happen precisely at 13:20.
I think this sets the stage. It’s 21:30, only 6.5 hours until duty calls. Time to get some sleep. If I could only lower my level of excitement!

The Orion program showed its resilience this year during an unprecedented time, racking up several success stories building and testing the spacecraft in preparation for upcoming Artemis missions to the Moon. From hot fire and structural testing, to crew and service module assembly activities, progress on Orion brought the agency closer to sending the first woman and next man to the Moon by 2024, and sustainable lunar exploration by 2028.
Ensuring crew safety, a hot fire test was conducted on the Northrop Grumman-built attitude control motor – which provides steering for Orion’s launch abort system in the event of an emergency during ascent – at the company’s facility in Elkton, Maryland. The 30-second hot fire was the third and final test to qualify the motor for human missions, beginning with Artemis II.
During a three-month testing campaign at NASA’s Plum Brook Station in Sandusky, Ohio, the Orion spacecraft was subjected to the extreme temperatures and electromagnetic environment it will experience on Artemis I – Orion’s first uncrewed test flight to the Moon atop the agency’s Space Launch System (SLS) rocket. Testing wrapped up early and the vehicle was readied for its journey back to NASA’s Kennedy Space Center aboard the agency’s one-of-a-kind Super Guppy.
Before NASA astronauts fly Orion on missions to the Moon and back, testing is necessary to verify the spacecraft’s ability to withstand the stresses of launch, climb to orbit, the harsh conditions of deep space transit, and return to Earth. Engineers from NASA and its prime contractor, Lockheed Martin, completed testing on Orion’s Structural Test Article (STA) for Artemis I. The STA is structurally identical to Orion’s main spacecraft elements: the crew module, service module and launch abort system.
The first element machined for the Artemis III Orion crew module – a cone panel with openings for windows, which will provide a spectacular view – was designed by Lockheed Martin, and manufactured by AMRO Fabricating Corp., of South El Monte, California. The completed panel made its way to NASA’s Michoud Assembly Facility near New Orleans, where engineers will weld it with other elements as part of Orion’s pressure vessel.
Orion’s European Service Module primary structure for the Artemis for the Artemis III mission arrived at the Airbus facility in Bremen, Germany, from its Thales Alenia Space manufacturing site in Turin, Italy. The service module will be equipped with components to power Orion and provide life support to astronauts – such as air, water, heat and cooling – during the mission that will land the first woman and next man on the Moon.
Three spacecraft adapter jettison fairing panels were fitted onto Orion’s service module inside the Neil Armstrong Operations and Checkout Building at Kennedy. Once secured, the panels encapsulate the service module to protect it from harsh environments such as heat, wind, and acoustics as the spacecraft is propelled out of Earth’s atmosphere atop the SLS rocket during NASA’s Artemis I mission.
Will NASA send astronauts to the moon again or any other planet within the next ten years?
@nasaorion spacecraft will launch on the Space Launch system (the largest spacecraft every built, even bigger than the Saturn V rocket!). Both are under construction @nasa currently, and this is the spacecraft that will take us beyond the low earth orbit of the International Space Station, whether that be the Moon, Mars, or beyond. We will conduct test missions with astronauts on Orion in the early 2020s, and a first mission will take us 40,000 miles beyond the Moon!
What would you take with you to the Moon? 🧳
We’re getting ready for our Green Run Hot Fire test, which will fire all four engines of the rocket that will be used for our Artemis I mission. This test will ensure the Space Launch System rocket is ready for the first and future missions beyond Earth’s orbit, putting us one step closer to landing the first woman and the next man on the Moon!
