Toyota Reveals ‘Self-Driving Electric Moon Car’ As Japan Prepares To Land Astronauts On The Moon

Japan is planning a moon landing for 2029 and wants its astronauts to explore the lunar surface in a vehicle built by Japanese automaker Toyota.

The Japan Aerospace Exploration Agency (JAXA) and Toyota announced Tuesday that it will collaborate on international space exploration, specifically on developing a manned, pressurized rover that uses Toyota’s fuel cell vehicle (FCV) technologies.

“Manned, pressurized rovers will be an important element supporting human lunar exploration, which we envision will take place in the 2030s, ” said Koichi Wakata, JAXA Vice President. “We aim at launching such a rover into space in 2029.”

JAXA, which earlier this month landed its Hayabusa2 probe on the asteroid Ryugu, is hoping the collaboration with Toyota will “give rise to intellectual properties” needed for international space exploration.

An FCV is a type of electric vehicle that, instead of using a battery, uses a fuel cell of oxygen and compressed hydrogen, which react with each other to generate electricity. The zero-emissions technology is already used on Toyota’s Mirai vehicle. “Fuel cells, which use clean power-generation methods, emit only water, and, because of their high energy density, they can provide a lot of energy, making them especially ideal for the project being discussed with JAXA,” said Shigeki Terashi, Executive Vice President at Toyota. He also mentioned that Toyota’s automated driving technologies were part of the project.

Although the amount of fuel that could be taken to the moon would be limited, said JAXA and Toyota, the pressurized rover would have a total lunar-surface cruising range of more than 10,000 km.


However, Toyota’s ‘space mobility’ concept for the pressurized rover being studied by JAXA and Toyota is pretty small. It envisions a 6 meter by 5.3-meter vehicle standing 3.8 meters tall. That’s enough room for two people, say JAXA and Toyota, or four in an emergency. Toyota and JAXA also revealed that they have been jointly studying the concept of a manned, pressurized rover since May 2018.

The moon presents some special challenges for any vehicle. Gravity is one-sixth of Earth’s, and the lunar surface is pocked by craters, cliffs, and hills. “It is exposed to radiation and temperature conditions that are much harsher than those on Earth, as well as an ultra-high vacuum environment,” said Wakata. “For a wide-ranging human exploration of the moon, a pressurized rover that can travel more than 10,000 km in such environments is a necessity.” Wakata also stressed the need for a ‘Team Japan’ approach to space exploration.

That’s a message that appears to be finding favor. Japan Airlines-backed startup ispace last month announced that its HAKUTO-R mission will orbit the moon in 2020 ahead of a mission to land on the surface in 2021. An finalist in the ill-fated Google Lunar XPRIZE, ispace plans to map, and eventually recover, water ice on the moon and learn how to use it as a resource. If it can separate lunar water into hydrogen and oxygen, it could provide fuel for Toyota’s moon buggy, as well as for a self-sufficient moonbase, and even rockets.

Aside from Japan Airlines, HAKUTO-R’s corporate partners include Japanese national daily newspaper Asahi Shimbun and Japan NGK Spark Plug, which wants to test solid-state battery technology on the moon in 2021. Another is Mitsui Sumitomo Insurance, which last month announced a new lunar insurance service. “The availability of lunar exploration insurance will encourage new players to participate in the lunar industry by reducing the risk of entry,” said ispace founder Takeshi Hakamada last month. “With the ability to insure our landers and rovers, ispace and its customers will be able to concentrate on realizing our vision without hesitation.”

Unusual signals come from the GJ 1151 system

Most likely, radio emission is created by the interaction of a planet the size of the Earth with the strong magnetic fields of its star.

Using the LOFAR low-frequency radio telescope, astronomers recorded unusual radio emission coming from the red dwarf GJ 1151, which is located at a distance of about 28 light-years from Earth, these signals, according to scientists, contain evidence of the auroras created by the interaction of the planet with the strongest magnetic fields of the star. The results of the study are presented in the journal Nature Astronomy.

“Radio emission from the interaction of a star and a planet was predicted more than thirty years ago, but only now we were able to identify its signature in the data. Success achieved paves the way for a new way to detect exoplanets in the habitable zone and study their surroundings, ”the authors of the study say.

Red dwarfs are the most common type of star in the Milky Way. They are much smaller and colder than the Sun and have extremely strong magnetic fields. This means that any potentially inhabited planet in the system of such a star, due to its proximity to it, is subjected to intense magnetic activity, which can heat it and even destroy the atmosphere. The radio emission associated with this process is one of the few tools available to evaluate this effect.

“The movement of the planet through the strong magnetic field of the red dwarf acts like an electric motor. This process generates a huge current that provokes radiance and creates radio emission, ”explained Harish Vedantam, lead author of the study from the Netherlands Institute of Radio Astronomy.

In the solar system, similar currents are not generated due to the weak magnetic field of the sun and the large distance to the planets. However, the interaction of the Io satellite with the magnetic field of Jupiter also creates a fairly bright radio emission, at low frequencies superior to the sun.

“We adapted our knowledge from decades of radio observations of Jupiter to the data on the star GJ 1151. For many years it was predicted that the Jupiter-Io system should exist in a larger version of the star-planet, and the radiation recorded by us from GJ 1151 is very well consistent with theory. Today we know that almost every red dwarf contains terrestrial planets, so there must be other stars showing such radiation,” Joe Cullingham added, the co-author of a study from the Netherlands Institute of Radio Astronomy.

Astronomers note that the sensitivity of modern instruments should allow them to find about a hundred more of such systems in the solar vicinity, and, more importantly, assess the conditions in which exoplanets reside in them.

“The main goal is to determine what effect the magnetic activity of a star has on the habitability of an exoplanet, and radio emission is the most important link in this puzzle,” Harish Vedantam concluded.

Mankind may face deadly viruses in search of new life in space

Professor Dov Greenbaum hypothesized that humanity’s search for signs of life outside the Earth could lead to an even greater threat of infection than a new kind of coronavirus.

In his material, the scientist notes that in the era of human mobility, new viruses spread very quickly, while bacteria grown in outer space can become even more deadly.

For a more detailed study of this issue, samples of genetically engineered bacteria samples are sent aboard the ISS. Despite the fact that the spread of extraterrestrial viruses in real life is considered a very unlikely scenario, the scientist warns against excessive optimism. The astrobiologist claims that dangerous viruses and infections can live in space on rocks that seem dead to the surface. In connection with these, Greenbaum believes that in the case of the reality of the existence of extraterrestrial life forms, their search without appropriate precautions “can lead to infections that will be even more dangerous and deadly than the acclaimed coronavirus.”

The professor also recalled that life was found in those places that were previously considered impossible for the existence of living organisms. So, NASA is going to deliver stones from the surface of Mars, and the Japanese space mission is already returning from the asteroid Ryugu with samples of its rock. At the end of this year, the Japanese Hayabusa2 will reach Earth. According to Greenbaum, it is likely that one of these missions will deliver a fundamentally new type of space infections to Earth.

Unknown carbon form found in Chelyabinsk meteorite

Scientists have discovered an unknown form of carbon on Earth in fragments of a meteorite that fell in the Chelyabinsk region in 2013, said Sergei Zamozdra, assistant professor of theoretical physics at the Chelyabinsk State University.

He said that the dean of the Faculty of Physics Sergey Taskaev (now the rector of the university. – Ed.), while studying samples of meteorite dust, noticed something amazing.

“At first he thought it was a diamond, because there were six faces. Later in Germany, this crystal was pulled out using micro-tweezers and when X-rayed – it turned out to be not a diamond, but a carbon crystal. We measured the position of atoms, the planes of interatomic, then Korean specialists on a computer calculated that, indeed, such an arrangement of atoms is possible, “he explained.

According to the scientist, carbon can have many modifications. However, such carbon has not yet been found on Earth, and experts will have to figure out how it came about, calculating different options.

“One option is that it arose in space conditions, because we are talking about a process of billions of years. Another is directly during a flight in the Earth’s atmosphere,” the scientist believes.

According to the press service of Chelyabinsk State University, the study of meteorite fragments was carried out by Sergey Taskaev together with colleagues from the Technical University of Darmstadt (Germany) and the National University of Kengpuk (Republic of Korea).

In the Chelyabinsk region on February 15, 2013, thousands of people watched a very bright object in the sky. In the first minutes, the expansion and twisting of its smoky plume was visible, followed by an air wave strike, similar to the sound of a strong explosion.

Fragments of the meteorite were found in the vicinity of Chebarkul, but the largest – more than 600 kilograms – was raised from the lake of the same name. Now it is stored in Chelyabinsk in the South Ural State Historical Museum under a special dome in the exhibition hall, where everyone can see it.
