Chalk River’s Bubble Technology Industries looking for water on the Moon

Published

 on

CHALK RIVER — Bubble Technology Industries (BTI) announced Nov. 15 that it is part of the team that has received a $43 million contract from the Government of Canada to design and build Canada’s first lunar rover, which will carry multiple science payloads to the Moon as early as 2026. The team will be led by Canadensys Aerospace and includes a broad team of Canadian and partners from industry and academia in the United States.

Initiated under the Canadian Space Agency’s Lunar Exploration Accelerator Program (LEAP), the lunar rover will demonstrate key technologies and collect important scientific data to lay the foundation for future lunar exploration activities. BTI is responsible for one of the payloads in the form of the Lunar Hydrogen Autonomous Neutron Spectrometer (LHANS). LHANS is an advanced instrument designed to detect hydrogen — one of the best indicators of water ice on the Moon — as well as other key elements, like iron and calcium. According to a press release from BTI, the presence of water and other key elements on the Moon can make extended human stays on the Moon more feasible in the future.

“BTI is excited to be part of this world-class team that will expand human knowledge of the Moon and lay the foundation for a new phase of lunar exploration,” said Lianne Ing, vice president at BTI. “The work will leverage almost a decade of innovative research by our team at BTI and we look forward to contributing our expertise to this important mission.”

According to the Canadian Space Agency (CSA), the rover will be able to drive into and operate inside of permanently shadowed regions for up to one hour; survive lunar nights (-170C to less than -200C), which can last up to 14 Earth days; use multiple modes of communication; maximize lunar surface operations and scientific data return; and provide panoramic imagery and video of the lunar surface.

CSA said, rovers act like scientists’ eyes and hands — they help gather information on samples of elements at different locations, and send data back to Earth, as opposed to landers that can only analyze one location.

As part of the ongoing collaboration between the CSA and NASA, the Canadian lunar rover will fly as part of NASA’s Commercial Lunar Payload Services initiative and would land in the south polar region of the Moon as early as 2026.

An asteroid will whip by Earth tomorrow in one of closest approaches ever recorded

Published

 on

An asteroid the size of a delivery truck will whip past Earth on Thursday night, one of the closest such encounters ever recorded.

NASA insists it will be a near miss with no chance of the asteroid hitting Earth.

The U.S. space agency said Wednesday that this newly discovered asteroid will zoom 3,600 kilometres above the southern tip of South America. That’s 10 times closer than the bevy of communication satellites circling overhead.

The closest approach will occur at 7:27 p.m. ET.

Even if the space rock came a lot closer, scientists said most of it would burn up in the atmosphere, with some of the bigger pieces possibly falling as meteorites.

NASA’s impact hazard assessment system, called Scout, quickly ruled out a strike, said its developer, Davide Farnocchia, an engineer at the agency’s Jet Propulsion Laboratory in Pasadena, Calif.

“But despite the very few observations, it was nonetheless able to predict that the asteroid would make an extraordinarily close approach with Earth,” Farnocchia said in a statement.

“In fact, this is one of the closest approaches by a known near-Earth object ever recorded.”

Asteroid spotted by amateur astronomer in Crimea

Discovered Saturday, the asteroid known as 2023 BU is believed to be 3.5 to 8.5 metres across.

It was first spotted by Gennady Borisov, the same amateur astronomer in Crimea who discovered an interstellar comet in 2019.

Within a few days, dozens of observations were made by astronomers around the world, allowing them to refine the asteroid’s orbit.

The asteroid’s path will be drastically altered by Earth’s gravity once it zips by. Instead of circling the sun every 359 days, it will move into an oval orbit lasting 425 days, according to NASA.

Nuclear-powered spaceships? U.S. plans for 2027

Published

 on

WASHINGTON –

The United States plans to test a spacecraft engine powered by nuclear fission by 2027 as part of a long-term NASA effort to demonstrate more efficient methods of propelling astronauts to Mars in the future, the space agency’s chief said on Tuesday.

NASA will partner with the U.S. military’s research and development agency, DARPA, to develop a nuclear thermal propulsion engine and launch it to space “as soon as 2027,” NASA administrator Bill Nelson said during a conference in National Harbor, Maryland.

The U.S. space agency has studied for decades the concept of nuclear thermal propulsion, which introduces heat from a nuclear fission reactor to a hydrogen propellant in order to provide a thrust believed to be far more efficient than traditional chemical-based rocket engines.

NASA officials view nuclear thermal propulsion as crucial for sending humans beyond the moon and deeper into space. A trip to Mars from Earth using the technology could take roughly four months instead of some nine months with a conventional, chemically powered engine, engineers say.

That would substantially reduce the time astronauts would be exposed to deep-space radiation and would also require fewer supplies, such as food and other cargo, during a trip to Mars.

“If we have swifter trips for humans, they are safer trips,” NASA deputy administrator and former astronaut Pam Melroy said Tuesday.

The planned 2027 demonstration, part of an existing DARPA research program that NASA is now joining, could also inform the ambitions of the U.S. Space Force, which has envisioned deploying nuclear reactor-powered spacecraft capable of moving other satellites orbiting near the moon, DARPA and NASA officials said.

DARPA in 2021 awarded funds to General Atomics, Lockheed Martin and Jeff Bezos’ space company Blue Origin to study designs of nuclear reactors and spacecraft. By around March, the agency will pick a company to build the nuclear spacecraft for the 2027 demonstration, the program’s manager Tabitha Dodson said in an interview.

The joint NASA-DARPA effort’s budget is US$110 million for fiscal year 2023 and is expected to be hundreds of millions of dollars more through 2027.

The green comet ZTF returns to the solar system 50,000 years later… and it will be visible from Earth

Published

 on

For astronomy enthusiasts, February 1 is marked in red on their calendars. The reason: it is not every day that there is a chance to see a green comet.

In fact, it is the first time in 50,000 years that C/2022 ZTF will return to the solar system. And it will be early next month when it will reach its closest position to Earth.

Specifically, the green comet ZTF will pass 42 million light years from our planet. Experts are not 100 percent sure whether it will be visible from the surface without the use of any instrument. However, if we have specific astronomy binoculars or telescopes, we will be able to see it without any problem.

As usually happens in these cases, the best places to observe the comet, this one or any other, are places with little artificial light. That is to say, we should move away from urban centres and it is preferable to do so in the hours before dawn.

Why is comet ZTF green?

Comet ZTF has a brightness and a colour that, although not unique, is clearly distinctive. Its hue is due to the fact that it is composed, among other materials, of diatomic carbon.

When it comes into contact with sunlight, the decomposition of this element causes the gas to acquire this spectacular colour.

Comet ZTF was discovered in March 2022

Frank Masci and Bryce Bolin of the Palomar Observatory in California were responsible for spotting the striking comet ZTF in the sky. It is so named because its discovery is part of the Zwicky Transient Facility surveillance programme, which uses the powerful Schmidt telescope at the facility.

Initially, the scientists responsible for the discovery thought it was an asteroid, but they quickly realised that this was not the case. Despite the striking colour of this comet, experts advise keeping expectations low. In any case, it is an event that has aroused great interest in the community.
