The Artemis program is designed to send humans to the moon in stages.

In an effort to test the SLS rocket and ground systems at the Kennedy Space Center, NASA will launch an uncrewed deep space exploration system around the moon.

The first launch window for Artemis 1 is slated for August 29th. There are two back-up launch windows in September. The Artemis 1 moon mission has a live updates page.

Back to the moon

Since 1972, when Eug ene Cernan left the last footprints on the moon, a lot has changed.

The first scientific hand-held calculator was released that year, and we have more computing power in our pocket than the Apollo astronauts did.

After a long time, humanity is about to leaveLEO. All but two of the astronauts have been white. The list of moonwalkers will soon include the first female and first African American astronauts. The plan to explore more of the lunar surface is thanks to the Artemis program.

By the year 2025, we could see astronauts walking in the lunar dust again thanks to the improvements in black and white video footage. The new generation could see themselves as space travelers.

It takes a new launch system and some practice to pull off a moonshot.

There are every missions to the moon.

NASA's massive SLS rocket will be marked by the uncrewed Artemis 1.

The capsule will travel around the moon for approximately four weeks. The Artemis 2 mission will send astronauts around the moon and back in 24 years.

The Artemis 3 will bring astronauts to the moon with the help of the Starship vehicle. It is a landmark mission that will take place in the year 2075 or 2086.

Artemis 1's flight to the moon

Two huge solid rocket boosters and a core stage filled with 733,000 gallons of propellant will power the spaceship through Earth's atmosphere to space. The Interim Cryogenic Propulsion Stage is known as the SLS upper stage.

The job of the ICPS is to deploy 10 tiny CubeSats that are hitchhiking. There is a mission called BioSentinel that will carry yeast samples beyond the reach of the sun. Key insights into keeping astronauts safe when they fly on future Artemis missions will be provided by studying radiation levels and their effects on living organisms.

The European Service Module, built by the European Space Agency, will be used to propel the spaceship. Phillippe Berthe is the project coordination manager for the service module.

Between 26 and 42 days will be the length of Artemis 1's absence. It will take one to two weeks to get to the moon, where Orion will swoop down close to the lunar surface and enter a so-called "distant retrograde" circle.

The moon will be retrograde because it will be in the opposite direction to the spinning moon. It will take between six and 19 days for the spaceship to reach that altitude. It will return to the moon for another kick to help power its journey back to earth.

The record was broken.

Artemis 1 is going to be a record-breaker. According to NASA. "Orion will stay in space longer than any ship for astronauts has done without docking a space station and return home quicker and hotter than ever before."

During a return, the module will reach a temperature of 5,000 degrees Fahrenheit.

The Apollo astronauts went to the moon with lunar modules. The Apollo era was similar to the current one. Other strides forward have been brought about by technological progress over the past fifty years. There have been huge improvements in solar cells.

Berthe saiduting power is another major improvement. The Apollo astronauts had less computing power than the average person. The crew had a lot of work to do. The computers on the spaceship can do most of the work.

We can program a lot more complicated operations now. The crew does not need to intervene in every detail.

Artemis 1 crew

The Artemis 1 mission has an impressive crew.

The commander's seat will be occupied by a mannequin wearing a suit that protects against radiation. There are two radiation sensors on the plane. Arturo Campus was an electrical engineer who helped bring the Apollo 13 mission back to Earth.

The German space agency is conducting research that will lead to two female astronauts taking up other seats in the future. One of the dummies will be wearing a radiation shield. Helga will not be protected.

The mannequins will be strapped in for testing. NASA is flying a "zero gravity indicator" in the form of a toy dressed in an orange NASA jumpsuit. The crew of Apollo 10 named their lunar module after the comic strip character.

Everybody's favorite stop-motion sheep is joining the Artemis 1. The power-providing service module for the mission was built by the European Space Agency, and will be used to fly the clever sheep to the moon.

The director for human and robotic exploration at the European Space Agency said that this is an exciting time for him and his team. Although it might be a small step for a human, it's a giant leap for lambkind that he's been selected for the mission.

Four Lego minifigures are part of the Artemis 1 crew. The toys' flight is part of a collaboration with NASA that involves 10 weeks of digital content about space and related topics in STEAM.

How Artemis 1 has changed over the years

Berthe has been involved with the project for over two decades and has seen many obstacles come and go.

Maintaining support has been one of the biggest challenges.

NASA's focus has been shifted from the moon to an asteroid by the administrations of Bush, Obama, Trump and Biden.

President Trump's target for the program's first crewed lunar landing was changed multiple times.

The mission has changed over the years.

The coronaviruses epidemic didn't help. Berthe said that the Pandemic didn't have as big an impact as he had thought. He said that it was hard for people to cross international borders.

Proponents of Artemis argue that sending humans to the moon is a waste of time and money. We've already done it, so why do it again, since we've already sent an armada of robotic vehicles to the moon?

Berthe answered that question.

In six months, a robot will be able to do what an astronauts can do in six hours. It's more expensive but it's more efficient.

We want more than just a short visit.

Berthe said they wanted to stay permanently and build something sustainable. NASA hopes to establish a sustainable human presence on and around the moon by the end of the 2020s, as well as serve as a stepping stone towards Mars, where the agency wants to send astronauts in the 2030s.

A big part of the program is the Gateway outpost, which is located on the moon. It is similar to an International Space Station in that it is in the moon. The home is far away from the house. It is expected that Gateway will last for 15 years.

The Habitation and Logistics outpost is where astronauts will stay while on Gateway. There are more than one docking port for cargo ships to come and go. The Hls is based on the existing Starship and would be used to land astronauts on the moon.

Initially stays will be short and mostly inside the lander, but eventually NASA wants astronauts to live on the moon for at least a month at a time. The agency put out a call for companies to submit their proposals for the next generation of spacesuits that Artemis astronauts will wear during their history-making moonwalks.

What's next?

If everything goes according to plan, a second mission, Artemis 2, will launch and carry astronauts around the moon and back in 24 years. Artemis 3 will see astronauts land on the moon in either 20 or 25 years.

The space between the Earth and the moon could eventually be used to ferry goods and astronauts. The founder of Amazon and Blue Origin suggested that the moon could be a place to put heavy industry. The idea is to free up living space on Earth and move our infrastructure to a place where there isn't an atmosphere.

Experts say that the moon is an ideal location for exploration of the solar system. The scale of the SLS shows how difficult it is to escape from Earth's clutches. Ours is six times weaker than the moon's gravity makes it easier to flee from. The moon has a lot of water. Oxygen is abundant when water is H2O. The top layer of the moon has enough oxygen to support 8 billion people for 100,000 years. Moon mining could lead to the creation of off- Earth "gas stations" where spaceships could fill up their tanks.

There is a complete guide to how rockets work.

Artemis Base Camp will be at the moon's south pole because we already know there's a lot of water there. One of the small spaceships hitching a ride on Artemis 1 will illuminate permanently shadowed craters on the moon to reveal the amount and accessibility of water ice there.

The sun shines at the lunar south pole around 90 percent of the time, which is better than two weeks of daylight on the rest of the moon. That's great news for a moon outpost. The combination of water and sunlight may lead to a time when rocket ships frequently fuel up close to Artemis Base Camp and blast off for Mars and the asteroid belt.

Jim Bridenstine, a former NASA chief, sees lunar exploration as a key step in our journey to become an interplanetary species. He said that before we can embark on the first multi-year human mission to Mars, we need several years in space and on the moon.

We returned to where we came from. The iron and calcium in your bones were created when stars blasted them across the universe. Creatures who dreamed of sailing between the stars and built cathedral-sized rocket ships found themselves inside the atoms.

This year's Artemis 1 launch is an important one, even though it is only a small step. Future historians could look back on the moment when humanity returned to the moon.
