Europe’s space sector to soon welcome Ariane 6: ‘The missions will be longer and more versatile’ – Euronews

Posted: June 1, 2024 at 10:41 pm

The new Ariane 6 rocket will close a dark chapter in European space history when the region had no workhorse launcher and no independent access to space.

What's Ariane 6 like? What's new about it? What space adventures await?

Euronews' Marta Rodrguez Martnez and David Walsh travel to the European space station in Kourou, French Guiana, to learn all about it.

The last Ariane 5 rocket completed its final mission on July 5, 2023, after 27 years in service. The development of its successor Ariane 6 began almost a decade ago.

"During those nine years in which we developed Ariane 6, we introduced changes with a prime contractor and the industrialist to better serve evolving needs," explains Luca Linares, the European Space Agency's Head of Strategy and Institutional Launches.

"That's the life of a means of transport to space or on Earth".

So, how different is Ariane 6 from its predecessor?

Versatility is the key attribute emphasised by officials in Kourou. Ariane 6 needs to be highly adaptable to compete in a market disrupted by Elon Musks company SpaceX.

SpaceX's reusable rockets represent a major milestone in the space industry, making space travel more accessible and efficient by reducing costs.

"We can fly with three recognisable engines in three different missions. We have special equipment on board, the so-called APU (Auxiliary Power Unit), that helps us reignite the engine and bring our customers to completely different points in space and deliver them there," says Jens Franzeck, Chief Operating Officer and Managing Director of ArianeGroup.

"This is a huge difference. The missions will be longer, more versatile, and sometimes more complex. And this is where we want to go".

Ariane 6 can also operate with two or four boosters, depending on the thrust, orbit, and payload of the mission in question. Each booster, developed to flank the core, weighs 153 tons.

"Moving from Ariane 4 to Ariane 5 was a significant step because Ariane 4 used storable propellants, while Ariane 5 used liquid hydrogen and oxygen. This made the launch base for Ariane 5 completely different from that of Ariane 4, which caused many difficulties," says Jean-Michel Rizzi, Ariane 6 Launch Base Manager at ESA.

"However, the processes for Ariane 6 are almost identical to those of Ariane 5," he said.

Up to thirteen European countries, led by France, have collaborated on the development of Ariane 6.

Italian aerospace companies have provided propulsion systems. Belgium's science policy office, BELSPO, and Belgian companies have contributed their expertise in areas such as telecommunications and satellite technology.

Spanish companies have been involved in structural components and ground support equipment.

Swiss companies have contributed precision engineering and components to the Ariane 6 programme, particularly in areas such as guidance and navigation systems.

Dutch companies have provided expertise in areas such as avionics and payload integration for Ariane 6 missions.

The year 2024 is poised to be a landmark in the history of space exploration, with Ariane 6 joining an elite class of powerful rockets preparing to leave Earth.

On March 6, NASA successfully completed the sixth of 12 scheduled RS-25 engine certification tests for the Space Launch System (SLS), a pivotal component of the Artemis programme.

This launcher is central to NASA's ambitions to return humans to the Moon and eventually conduct crewed missions to Mars.

Meanwhile, Elon Musk's SpaceX also has its sights set on lunar exploration. The company plans to conduct the fourth flight test of its Starship mega-rocket in June.

This colossal rocket is essential for SpaceXs goal to send both equipment and humans to the Moon and, ultimately, to Mars, reinforcing its vision of making humanity a multi-planetary species.

South Korea will fly to Mars in 2045 – The Universe. Space. Tech

Posted: at 10:41 pm

South Korea, which recently created its own space agency like NASA, is serious about becoming one of the leading space powers. Already in 2032, the country plans to land its probe on the Moon, and an automatic mission to Mars is planned for 2045.

In 2045, the Korean probe is scheduled to make a soft landing on Mars. This statement was made on Thursday, June 30 by the countrys President Yoon Suk Yeol. According to him, the government plans to spend $70 billion on space exploration in the coming years.

All this is being done in order to make South Korea a leading space power that could compete with China, India and Japan. This should be facilitated by the recently created Korea Aerospace Administration (KASA), modeled after NASA. It will be headed by John Lee, who has worked for 30 years in the relevant structures of the United States.

In general, the Korean president is highly counting on rapid space exploration. After all, according to him, there is a dream beyond the Earth. In order to achieve it next year, the KASA budget will almost double and amount to 1.1 billion dollars.

South Korea plans to develop its space science gradually. It intends to start with the fact that in 2025 it will launch its new Nuri rocket again. It became a real sensation when last year, on the third attempt, it was able to put a satellite into orbit.

Further plans are related to the Moon. South Korea already sent the Danuri spacecraft there in 2022. However, its further steps in this direction will be related to the planned return of American astronauts to the Earths moon in 2026.

Regardless, in 2032, KASA will try to land its own probe on the moon. Next, the Koreans plan to actively involve the private sector in missions, and in 2045 it will finally be Mars turn.

15 of the Most Life-Changing Spacecraft and Missions That Fueled Our Curiosity – DISCOVER Magazine

Posted: at 10:41 pm

Starting with the Space Race of the 20th century, humans have embarked on a journey through time and space with some of the most pioneering and life-changing space missions.

As we stand on the cusp of another age of space exploration with the upcoming Artemis missions and other space observatories set to go online this year, here are 15 space missions that not only set the groundwork for the future, but also ignite our curiosity about the universe we inhabit.

Sputnik 1 was the first successful artificial satellite placed in low-Earth orbit in 1957. While in orbit, Sputnik 1 gathered data on the upper layers of Earth's atmosphere. During its mission, the satellite completed 1400 orbits around Earth.

In 1958, the United States launched its first successful satellite, Explorer 1. It launched on January 31, 1958 and marked the beginning of the U.S. Space Age. The satellite was launched as a response to the launch of the Soviet Union's Sputnik 1 satellite.

Explorer 1 found evidence of radiation belts around Earth with its cosmic ray detector. Another satellite confirmed the find a few months later.

Eleven years after the launch of the Explorer 1 satellite, the U.S. launched the Apollo 11 mission on July 16, 1969. It was the first crewed mission to land on the Lunar surface.

On July 24, 1969, the Apollo 11 mission successfully landed on the Moon. On that mission, Neil Armstrong became the first person to step on the Moon and said the famous line, "That's one step for man, one giant leap for mankind."

Edwin "Buzz" Aldrin was the second to step on the Moon. Michael Collins did not get to step on the Moon but was on the command module as the pilot orbiting the Moon. While there, the astronauts placed an American flag on the surface and collected lunar rocks and core samples that were later returned to Earth.

In 1971, the Soviet Union launched the World's first space station, Salyut, meaning salute in Russian, into space. The space station, which weighed 20 metric tons and had one docking port, was designed to function for only six months.

Salyut 1 and its other six renditions (seven in total) informed engineers for the next-generation module called Mir. Mir served as the space station while the International Space Station was built.

Between 1973 and 1974, NASA operated the first space station for the U.S., Skylab. In it, hundreds of experiments were carried out, including experiments on how humans adapt to zero gravity.

Skylab also housed an observatory and a workshop. Skylab hosted three crewed missions and was occupied with astronauts for 171 days. The space station's main objective was to show that humans could live in space for long periods.

Between 1984 and 1993, the International Space Station (ISS) was designed with international partners like Canada, Japan, and Europe. Russia later joined the partnership in 1993.

After its construction, parts of the ISS were launched into space in 1998. The space station serves as a site of international collaboration and experiments designed to improve life on Earth for everyone who inhabits it, according to NASA.

The ISS has advanced knowledge in biology, material and physical sciences, human physiology, and more. Currently, the ISS is expected to be an outpost and working laboratory until at least 2030.

NASA's space shuttle missions first launched in 1981, with its last mission bringing a close to the program in 2011. In total, the space shuttles flew 135 missions and aided in constructing the ISS.

In its three-decade stint, the fleet consisted of orbiters, Columbia, Challenger, Discover, Atlantis, Endeavour, and Enterprise, which was never flown in space. The orbiters were the first reusable spacecraft that launched into space like a rocket, moved in low-Earth orbit like a spacecraft, and landed back on Earth like an airplane on a runway, according to NASA.

After its launch in 1990, the Hubble Space Telescope gave us a new view and understanding of the universe. The telescope captured images from galaxies far away.

Aside from taking mesmerizing images of galaxies and nebulas, the Hubble Space Telescope aided astrophysicists in understanding atmospheric compositions of planets orbiting other stars and finding dark energy.

The telescope captured all these discoveries using ultraviolet and near-infrared wavelengths. The Hubble Space Telescope has logged 1.5 million observations, and over 20,000 scientific papers have been published on these discoveries.

One of Hubble's most famous images is the Hubble Deep Field. With this image alone, astrophysicists could peer back in time and look at multiple galaxies in different stages of evolution since the Big Bang 13.5 billion years ago. The photo was taken in 1995 over 10 days in December.

The Chandra X-ray Observatory launched in 1999 and has been taking X-ray images of our universe since then. It has captured the glowing structures around galaxies and nebulas.

With Chandra, its X-rays images allow astrophysicists to understand the universe's structure. The X-rays are caused by matter heating to millions of degrees and are found in places with high magnetic fields or extreme gravitational forces.

The Parker Solar Probe, launched in 2018, was the first spacecraft to fly through the Sun's corona in 2021. Its main mission was to study the solar wind and its evolution.

During its seven-year mission, the probe will orbit 24 times around the Sun and come as close as 4 million miles from the Sun's surface. With this mission, experts may learn more about space weather, the sources of solar particles, and differences between the Sun's corona and its surface.

Since the late 1990s, NASA has sent five rovers to Mars. The fleet of rovers has captured images of the Martian surface and mapped out its features.

The rovers are Sojourner, which landed on Mars in 1997; Spirit and Opportunity, which landed in 2004; Curiosity, which landed in 2012; and Perseverance, which landed in 2021. Together, these rovers have gathered evidence of water on Mars and looked for signs of life on the Red Planet.

Launched in December 2021, the James Webb Space Telescope (JWST) was designed as the next space observatory like the Hubble Space Telescope to capture more data on the universe's evolution.

It's capable of seeing further than Hubble and will capture data about how the planets, stars, and the first galaxies formed.

To date, it has already provided clearer images of galaxies, and nebulas with its 18 hexagon-shaped mirrors, and four high-tech imaging instruments. JWST has also observed one of the farthest and youngest galaxies we have ever observed, GN-z11, and supermassive black holes that date to the early universe.

The European Space Agency set off to find planets, explore the universe's secrets, and study dark matter and energy to see why it looks as it does today with the Euclid Spacecraft.

Launched on July 1, 2023, the Euclid spacecraft will map out the scale of the universe. New images of the universe were recently released on May 23, 2024.

When the Vera C. Rubin Observatory goes online later this year, it will use the largest digital camera ever built to understand dark matter and energy. The camera measures 5.5 feet and will take images at 3.2 gigapixels.

The giant telescope, with its 8.4-meter primary mirror and digital camera, will map out the Milky Way galaxy and the planets in our Solar System and track objects called 'transients' that move across the sky.

In about 4 nights, the telescope would have imaged the entire night sky. Each image the Vera C. Rubin Observatory will take will have a resolution of 3200 megapixels. In its 10-year survey, the observatory is expected to take 5.5 million images and detect 38 billion objects.

NASA's Artemis program is set on further exploring the Moon and bringing humans back to it. The missions on the Moon will serve as data to further prepare humans for more extended space missions, such as those to Mars. By 2026, NASA plans to launch the first crew, Artemis III, to land on the lunar surface to explore the Moon's South Pole.

What's the story

Last month, China's Tiangong space station became home to four zebrafish, who are reportedly thriving in the microgravity environment of their space aquarium. Astronauts on board have observed the fish exhibiting unusual directional behavior, including inverted swimming and rotary movement. A video by China National Space Administration shows zebrafish swimming aimlessly inside a glass cube. "Like astronauts, zebrafish need to pass through rounds of selection to become 'aquastronauts,'" said Wang Gaohong, a hydrobiology researcher at the Chinese Academy of Sciences.

The observed aquatic anomalies serve a scientific purpose. Researchers aim to study the effects of microgravity on vertebrates like zebrafish by monitoring their behavior, growth, and development. This will be achieved by analyzing water samples and fish eggs during the experiment. The data collected could offer insights into how space and cosmic radiation impact larger vertebrates such as humans, potentially guiding future space exploration efforts.

This isn't the first instance of fish being kept in space. In 1973, NASA sent two mummichog fish and 50 fish eggs to their Skylab space station. These pioneering piscines swam in elongated loops due to their inability to discern up from down in zero gravity. They eventually oriented their backs to the lights inside Skylab as a means of navigation, providing an early glimpse into aquatic behavior in microgravity environments.

Like humans, fish also experience bone density loss in space. This was discovered by Japanese scientists who sent zebrafish and medaka to the International Space Station in 2012. Therefore, further studies on fish behavior in near-weightless environments could significantly enhance our understanding of the impact of space travel on human health. These findings underline the importance of ongoing research into how living organisms adapt to life beyond Earth's atmosphere.
