A Japanese space startup launched a spacecraft to the moon Sunday after several delays, a step toward what would be a first for the nation and for a private company.

Ispace Inc’s HAKUTO-R mission took off without incident from Cape Canaveral, Florida, after two postponements caused by inspections of its SpaceX Falcon 9 rocket.

More than a hundred people at a viewing party in Tokyo roared in applause when the rocket fired and lifted into the dark skies.

“I’m so happy. After repeated delays, it’s good that we had a proper launch today,” said Yuriko Takeda, a 28-year-old worker at an electronics company who joined the gathering.

“I have this image of the American flag from the Apollo landing, so while this is just the launch, the fact that it’s a private company going there with a rover is a really meaningful step.”

The national space agencies of the United States, Russia and China have achieved soft landings on Earth’s nearest neighbor in the past half century, but no companies have.

Mission success would also be a milestone in space cooperation between Japan and the United States at a time when China is becoming increasingly competitive and rides on Russian rockets are no longer available in the wake of Russia’s invasion of Ukraine.

It would also cap a space-filled few days for Japan, after billionaire Yusaku Maezawa revealed on Friday the eight crew members he hopes to take on a SpaceX flyby of the moon as soon as next year.

The name HAKUTO refers to the white rabbit that lives on the moon in Japanese folklore, in contrast to the Western idea of a man in the moon. The project was a finalist in the Google Lunar XPRIZE before being revived as a commercial venture.

Next year is the Year of the Rabbit in the Asian calendar.

The craft, assembled in Germany, is expected to land on the moon in late April.

The company hopes this will be the first of many deliveries of government and commercial payloads. The ispace craft aims to put a small NASA satellite into lunar orbit to search for water deposits before touching down in the Atlas Crater.

The M1 lander will deploy two robotic rovers, a two-wheeled, baseball-sized device from Japan’s JAXA space agency and the four-wheeled Rashid explorer made by the United Arab Emirates.

It will also be carrying an experimental solid-state battery made by NGK Spark Plug Co.

“The Rashid rover is part of the United Arab Emirates ambitious space program,” said Dubai ruler Sheikh Mohammed bin Rashid al-Maktoum, who is also vice president of the United Arab Emirates and who watched the launch at the Mohammed bin Rashid Space Centre.

“Our aim is knowledge transfer and developing our capabilities and to add a scientific imprint in the history of humanity,” he tweeted.

Privately funded ispace has a contract with NASA to ferry payloads to the moon from 2025 and is aiming to build a permanently staffed lunar colony by 2040.

After making a close pass at the moon and venturing further into space than any previous habitable spacecraft, NASA’s Orion capsule is due to splash down Sunday in the final test of a high-stakes mission called Artemis.

As it hurtles into Earth’s atmosphere at a speed of 40,000 kph, the gumdrop-shaped traveler will have to withstand a temperature of 2,800 degrees Celsius — about half that of the surface of the sun.

Splashdown in the Pacific off the Mexican island of Guadalupe is scheduled for 1739 GMT (9:39 am local time).

Achieving success in this mission of just over 25 days is key for NASA, which has invested tens of billions of dollars in the Artemis program due to take people back to the moon and prepare for an onward trip, someday, to Mars.

So far, the first test of this uncrewed spacecraft has gone very well.

But it is only in the final minutes of this voyage that the true challenge comes: seeing if Orion’s heat shield, the biggest ever built, actually holds up.

“It is a safety-critical piece of equipment. It is designed to protect the spacecraft and the passengers, the astronauts on board. So the heat shield needs to work,” said Artemis mission manager Mike Sarafin.

A first test of the capsule was carried out in 2014 but that time the capsule stayed in Earth’s orbit, so it came back into the atmosphere at a slower speed of around 32,000 kph.

Choppers, divers and boats

A U.S. Navy ship, the USS Portland, has been positioned in the Pacific to recover the Orion capsule in an exercise that NASA has been rehearsing for years. Helicopters and inflatable boats will also be deployed for this task.

The falling spacecraft will be slowed first by the Earth’s atmosphere and then a web of 11 parachutes until it eases to a speed of 30 kph when it finally hits the Pacific.

Once it is there, NASA will let Orion float for two hours — a lot longer than if astronauts were inside — to collect data.

“We’ll see how the heat soaks back into the crew module and how that affects the temperature inside,” said Jim Geffre, NASA’s Orion vehicle integration manager.

Divers will then attach cables to Orion to hoist it onto the USS Portland, which is an amphibious transport dock vessel, the rear of which will be partly submerged. This water will be pumped out slowly so the spacecraft can rest on a platform designed to hold it.

This should all take about four to six hours from the time the vessel first splashes down.

The Navy ship will then head for San Diego, California, where the spacecraft will be unloaded a few days later.

When it returns to Earth, the spacecraft will have traveled more than 2 million kilometers since it took off Nov. 16 with the help of a monstrous rocket called SLS.

At its nearest point to the moon, it flew less than 130 kilometers from the surface. And it broke the distance record for a habitable capsule, venturing 432,000 kilometers from our planet.

Artemis 2 and 3

Recovering the spacecraft will allow NASA to gather data that is crucial for future missions.

This includes information on the condition of the vessel after its flight, data from monitors that measure acceleration and vibration, and the performance of a special vest put on a mannequin in the capsule to test how to protect people from radiation while flying through space.

Some components of the capsule should be good for reuse in the Artemis 2 mission, which is already in advanced stages of planning.

This next mission planned for 2024 will take a crew toward the moon but still without landing on it. NASA is expected to name the astronauts selected for this trip soon.

Artemis 3, scheduled for 2025, will see a spacecraft land for the first time on the south pole of the moon, which features water in the form of ice.

Only 12 people — all of them white men — have set foot on the moon. They did this during the Apollo missions, the last of which was in 1972.

Artemis is scheduled to send a woman and a person of color to the moon for the first time.

NASA’s goal is to establish a lasting human presence on the moon, through a base on its surface and a space station circling around it. Having people learn to live on the moon should help engineers develop technologies for a years-long trip to Mars, maybe in the late 2030s.
