Canadian rover helping in global search for frozen water on dark side of the moon

Published

EDMONTON — The Canadian lunar rover could soon help reveal the moon’s dark side.

The country’s first moon rover is set to put the Canadian Space Agency at the forefront of space exploration, helping in the global search for frozen water on the celestial body.

Tidally locked to the Earth, the moon doesn’t spin on its axis but only orbits the planet, leaving the far side permanently dark, cold and unexplored.

“That has always piqued everybody’s imagination: What is on the other side of the moon?” said Gordon Osinski, the principal investigator for the Canadian Lunar Rover Mission.

Osinski’s Canadian team, along with international partners, is preparing to send a 30-kilogram rover to the south polar region of the moonin search of preserved frozen water, possibly a few meters below the surface and mixed into the soil.

The discovery of ice could be a stepping-stone to further explorations of the solar system, including missions staffed by humans, said Chris Herd, a scientific investigator on the mission and University of Alberta planetary geologist.

Herd, who has previously worked on the Mars rover mission, said frozen water “can be extracted and used as a resource for the astronauts to survive.” He said the ice could also be split into hydrogen and oxygen for fuel, reducing the cost of bringing those supplies from Earth.

“It reduces the costs of sending humans to the moon (and) that’s the ultimate goal,” he said.

Osinski said there’s been renewed interest in moon exploration over the last five years, with more emphasis on sending astronauts back there.

The robot rover would play an integral part in realizing that dream, he added.

Christian Sallaberger, CEO of Canadensys Aerospace Corporation, said commercial expansion of the space industry is also playing a big role in reviving interest in revisiting the moon.

In November, Ottawa picked Canadensys to build the lunar rover and help with the scientific instruments meant to be shipped to the moon.

“The costs of the missions have come down, relatively speaking, to what they were in the past,” Sallaberger said. “In the ’60s, everything was government funded.”

The Ontario space company has been working in partnership with six Canadian universities and several international partners from the United States and the United Kingdom.

Canadensys would be building a robust rover that could handle extreme temperature swings — shifting from -200 C at night to more than 100 C during the day. It would also be able to tackle high radiation and jagged lunar surfaces while continuing to send data throughout the months it spends on the moon.

Working on solar power, the rover would go to sleep every 14 days and then work 24 hours a day, seven days a week, until the next cycle.

Scientists will not only be looking for solid water, but would be investigating the composition of the moon’s rocky surface, characterizing the radiation environment and taking high-resolution images, Sallaberger said.

“(It’s) the preparation for future human missions that this rover would be doing,” he said.

While Canada won’t be the first country to make a landing on the far side of the moon, it could be the first to explore the south pole of Earth’s natural satellite, believed to hold ice water in the permanently shadowed craters.

China became the first country to send its rover, Yutu-2, to the far side of the moon in 2019.

Osinski said there could be other countries launching their rovers to the far side of the moon before Canada’s goes.

But he said it’s still “incredibly exciting.”

“I almost have to keep pinching myself at times,” he said. “It’s everything I’ve been working towards for the last couple of decades.”

Now, he hopes to see the launch of the rover in three years, mounted on top of a rocket — most likely to take off from NASA Kennedy Space Center in Florida.

“Then, a few weeks later, it would land on the surface of the moon. I can’t think of anything more exciting.”

Solar Storm That Caused Dazzling Auroral Display Could Linger

Published

 on

(Bloomberg) — A brilliant display of northern lights touched off by a massive geomagnetic storm was visible to a wide swath of the world Friday, and the aurora could linger through Saturday in many places if the weather is clear.

Red, purple and green streamers of the aurora borealis dazzled viewers in North America on Friday and were seen much farther south than normal, with people in California, Arizona and Texas reporting they could see it, according to AccuWeather, Inc. Typically, the spectacular display is only visible in northern locales like Alaska, North Dakota, Canada and Iceland.

The display was touched off by a severe geomagnetic storm that peaked about 12:04 a.m. Friday, according to the US Space Weather Prediction Center, and if the weather is clear, more could be in store on Saturday.

A coronal mass ejection, an explosion of magnetic fields and plasma from the sun’s atmosphere, hit Earth early Friday with more force than initially forecast. These events can disrupt Earth’s magnetic field causing auroral displays, as well as disrupting satellites, communication and electric grids.

The US Space Weather Prediction Center had originally expected a G2 level storm Friday on its five-step scale, the event measured in at G4, one of the strongest triggered on Earth since 2017.

In addition to the dazzling auroral displays, a G4 storm can cause headaches for power grid operators and force spacecraft to adjust their orbits. The storm can also degrade satellite navigation, radio broadcasts and even cause pipelines to build up an electric charge. In early 2022, Elon Musk’s SpaceX lost 40 Starlink satellites because of a solar storm.

The impacts from the coronal mass ejection have trailed off, but energy coming from what scientists call a “coronal hole” will continue at least through Saturday and that could mean the aurora could be seen by viewers across Europe, Asia and North America through Sunday, the UK Met Office said on its website.

There are currently eight sunspot clusters visible on the side of the sun facing Earth, however another coronal mass ejection blasting toward us isn’t forecast, the UK Met Office said.

An airplane-sized asteroid will pass between the Earth and moon’s orbits Saturday

Published

 on

An asteroid dubbed “city killer” for its size will pass harmlessly between the moon and the Earth Saturday evening.

The asteroid 2023 DZ2 will pass at a distance of over 100,000 miles, less than half the distance between the Earth and the moon. It’s about 160 feet long — about the size of an airliner. An asteroid that size could cause significant damage if it hit a populated area, hence its nickname.

“While close approaches are a regular occurrence, one by an asteroid of this size (140-310 ft) happens only about once per decade, providing a unique opportunity for science,” NASA Asteroid Watch tweeted.

Astronomers from the International Asteroid Warning Network, established about 10 years ago to coordinate international responses to potential near-Earth object impact threats, will be monitoring and learning from this asteroid.

NASA Asteroid Watch called the opportunity “good practice” in case “a potential asteroid threat were ever discovered.”

Near-Earth objects are asteroids or comets that pass close to the Earth’s orbit, and they generally come from objects that are affected by other planets’ gravity, moving them into orbits that push them close to Earth, according to the United Nations Office for Outer Space Affairs.

The European Space Agency maintains a risk list of 1,460 objects, which catalogs every object with a non-zero chance of hitting Earth over the next 100 years. Asteroid 2023 DZ2, which is in orbit around the sun, is not on the risk list.

Large asteroid to zoom between Earth and Moon

Published

 on

On Saturday, the 2023DZ2 will come within a third of the distance from the Earth to the Moon.

A large asteroid will safely zoom between Earth and the Moon on Saturday, a once-in-a-decade event that will be used as a training exercise for planetary defence efforts, according to the European Space Agency.

The asteroid, named 2023 DZ2, is estimated to be 40 to 70 metres (130 to 230 feet) wide, roughly the size of the Parthenon, and big enough to wipe out a large city if it hit our planet.

At 19:49 GMT on Saturday, it will come within a third of the distance from the Earth to the Moon, said Richard Moissl, the head of the ESA’s planetary defence office.

Though that is “very close”, there is nothing to worry about, he told AFP news agency.

Small asteroids fly past every day, but one of this size coming so close to Earth only happens about once every 10 years, he added.

The asteroid will pass 175,000km (109,000 miles) from Earth at a speed of 28,000 kilometres per hour (17,400 miles per hour). The Moon is roughly 385,000km (239,228 miles) away.

An observatory in La Palma, one of Spain’s Canary Islands, first spotted the asteroid on February 27.

Last week, the United Nations-endorsed International Asteroid Warning Network decided it would take advantage of the close look, carrying out a “rapid characterisation” of 2023 DZ2, Moissl said. That means astronomers around the world will analyse the asteroid with a range of instruments such as spectrometers and radars.

The goal is to find out just how much we can learn about such an asteroid in only a week, Moissl said. It will also serve as training for how the network “would react to a threat” possibly heading our way in the future, he added.

The asteroid will again swing past Earth in 2026, but poses no threat of impact for at least the next 100 years – which is how far out its trajectory has been calculated.
