Ah Crap: The Arctic Is Releasing a Ton of New Greenhouse Gas – Futurism

Published

 on


Gas Leak

Figuring out when, and to what extent, the Arctic will melt and release greenhouse gases into the air has been a major challenge for environmental scientists. Now it seems like the process is already underway.

A team of Russian and Swedish scientists exploring the Arctic Ocean found that the continental slope near Siberia has already started to give off huge amounts of methane, which is an even more potent greenhouse gas than carbon dioxide, The Guardian reports. The methane, which is leaking into the ocean and the air, is a worrying new data point about the state of the climate.

Early Days

The scientists, who haven’t yet finished analyzing their data or sent it for review by an academic journal, stressed to The Guardian that they’re still at a very preliminary stage of their research. But their discovery is still ominous. If the Arctic is releasing carbon in mass quantities, it could trigger a feedback loop that worsens climate change and continues to give off even more greenhouse gases.

“At this moment, there is unlikely to be any major impact on global warming, but the point is that this process has now been triggered,” Örjan Gustafsson of Stockholm University told The Guardian. “This East Siberian slope methane hydrate system has been perturbed and the process will be ongoing.”

Unknown Impacts

It will be hard to tell what impact these Arctic greenhouse gases will have on the global environment — but the consensus among experts is that it could be disastrous.

“This is a new page,” Igor Semiletov of the Russian Academy of Sciences told The Guardian. “Potentially they can have serious climate consequences, but we need more study before we can confirm that.”

Footage shows catastrophic collapse of iconic Puerto Rico telescope – Global News

Published

 on


Dramatic video from Puerto Rico captures the moment when a 816-tonne platform came crashing down on the Arecibo Observatory, shattering one of the world’s largest telescopes and striking a crushing blow to the global scientific community.

The catastrophic collapse happened on Dec. 1, less than two weeks after the U.S. National Science Foundation (NSF) warned that such a disaster was imminent. The NSF had already shuttered operations at the facility after a suspension cable snapped and slashed a hole in the dish last month.

The telescope was the largest of its kind when it opened in 1963, and it has contributed to all manner of astronomical discoveries over the years, from asteroids to planets to mysterious radio signals in space. It also won a place in pop culture as the set for such films as Contact and GoldenEye, the first James Bond movie starring Pierce Brosnan.

The observatory’s telescope consisted of a 816-tonne reflector dish platform suspended 137 metres above a massive, bowl-like dish, which measured 305 metres across.

Suspension cables holding up the platform snapped on Dec. 1, dropping the heavy platform on the dish with a tremendous crash.

Video captured by the Arecibo control tower shows one of the three major cables snapping, causing the platform to swing down on the remaining cables before snapping them, too.

The footage shows the reflector dish platform falling apart in mid-air, while dragging down several support towers behind it.

Drone footage captured from one of the support towers shows the moment when the first cable snapped. The cable snapped at the tower, then the whole structure came crashing down, pulling other towers with it and cracking the bowl of the telescope. Large clouds of dust rose from the bowl after the catastrophe.

Jonathan Friedman, who worked for 26 years at the facility and still lives nearby, described the awful sound of the collapse in an interview with the Associated Press.

“It sounded like a rumble. I knew exactly what it was,” he said. “I was screaming. Personally, I was out of control. … I don’t have words to express it. It’s a very deep, terrible feeling.”

Many scientists, Puerto Rico residents and other public figures mourned the telescope’s loss after it was closed, and again after it collapsed.

Ángel Vázquez, the telescope’s director of operations, said it was no surprise when the telescope fell apart early Tuesday.

“It was a snowball effect,” he said. “There was no way to stop it. … It was too much for the old girl to take.”

Telescope Collapse – SaultOnline.com

PUERTO RICO, USA – The Arecibo Observatory collapsed on December 1, 2020.

The telescope was the biggest of it’s kind in the world until China built a bigger one in 2016.

Its 305-meter main dish was on the ground while the suspended platform weighing in at 150 tons carried antennas and other equipment suspended over it.

One of the main cables supporting the platform broke in August and then the rest let go Tuesday.

During its lifespan, it made numerous discoveries and was used as a radar to ping near-earth asteroids. It would document size, spin, orbit, and rotation. Without this telescope, there is not another one in the world with the precision capability to do so.

There have been calls on social media to rebuild however no plans for the future of the telescope have been completed.

NASA buying Moon dust for US$1 – CTV News

Published

 on


The U.S. space agency NASA awarded contracts to four companies on Thursday to collect lunar samples for US$1 to $15,000, rock-bottom prices that are intended to set a precedent for future exploitation of space resources by the private sector.

“I think it’s kind of amazing that we can buy lunar regolith from four companies for a total of $25,001,” said Phil McAlister, director of NASA’s Commercial Spaceflight Division.

The contracts are with Lunar Outpost of Golden, Colorado for $1; ispace Japan of Tokyo for $5,000; ispace Europe of Luxembourg for $5,000; and Masten Space Systems of Mojave, California for $15,000.

The companies plan to carry out the collection during already scheduled unmanned missions to the Moon in 2022 and 2023.

The firms are to collect a small amount of lunar soil known as regolith from the Moon and to provide imagery to NASA of the collection and the collected material.

Ownership of the lunar soil will then be transferred to NASA and it will become the “sole property of NASA for the agency’s use under the Artemis program.”

Under the Artemis program, NASA plans to land a man and a woman on the Moon by 2024 and lay the groundwork for sustainable exploration and an eventual mission to Mars.

“The precedent is a very important part of what we’re doing today,” said Mike Gold, NASA’s acting associate administrator for international and interagency relations.

“We think it’s very important to establish the precedent that the private sector entities can extract, can take these resources but NASA can purchase and utilize them to fuel not only NASA’s activities, but a whole new dynamic era of public and private development and exploration on the Moon,” Gold said.

“We must learn to generate our own water, air and even fuel,” he said. “Living off the land will enable ambitious exploration activities that will result in awe inspiring science and unprecedented discoveries.”

Any lessons learned on the Moon would be crucial to an eventual mission to Mars.

“Human mission to Mars will be even more demanding and challenging than our lunar operations, which is why it’s so critical to learn from our experiences on the Moon and apply those lessons to Mars,” Gold said.

“We want to demonstrate explicitly that you can extract, you can utilize resources, and that we will be conducting those activities in full compliance with the Outer Space Treaty,” he said. “That’s the precedent that’s important. It’s important for America to lead, not just in technology, but in policy.”

The United States is seeking to establish a precedent because there is currently no international consensus on property rights in space and China and Russia have not reached an understanding with the United States on the subject.

The 1967 Outer Space Treaty is vague but it deems outer space to be “not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.”
