The CHEOPS mission blasted off from Kourou, French Guiana atop a Russian Soyuz rocket on Wednesday. The launch came 24 hours after a first attempt was delayed shortly before liftoff because of a software problem in the upper stage of the rocket.
<p>Scientists have long theorized with near certainty that there are countless planets in the universe, given the sheer numbers of stars. But it has only been possible to truly prove this since the 1990s.</p><p>Since then, thousands of so-called <a href="https://www.dw.com/en/nasa-finds-more-earth-sized-planets-that-could-support-life/a-39320490" target="_blank">exoplanets,</a> i.e. planets outside our solar system, have been discovered. As of yet, we don't know what these planets consist of or whether they have atmospheres.</p><p>That's why the <a href="https://sci.esa.int/web/cheops/" target="_blank">CHEOPS mission of the European Space Agency (ESA)</a> is preparing to investigate some of the known exoplanets in more detail.</p>
Measuring the Light Intensity of Stars

Despite the fact that exoplanets are incredibly far away from us (far outside our solar system, orbiting around distant stars), the mission is actually not that expensive.</p><p>"CHEOPS is a small mission in terms of scope, cost and also in terms of the time it takes to develop the mission," says Kate Isaak, a scientific coordinator of CHEOPS. "The mission is to measure the size of planets orbiting nearby suns."</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjE5MTUzNy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyNTcxMzUzM30.cCVBNNCuBCxK-BDmjWT_HgMPcTUTkmx4SIXwTXYMjXk/img.jpg?width=980" id="50634" class="rm-shortcode" data-rm-shortcode-id="cd12848eb95b28e252631700fc170531" data-rm-shortcode-name="rebelmouse-image" /><p>And this is how it works: when a planet passes a star on its orbit, the star's light becomes darker for a short time. This is like a small solar eclipse that can be observed by CHEOPS.</p><p>And even if the same planet is placed behind the star from the point of the observer, it reflects the light of the star back. CHEOPS can still see that, too. Astronomers can compute the size of the planet from the attenuation of the light. And the light reflections emitted by the planet itself provide clues as to whether, for example, it has an atmosphere.</p>
A Closer Look at Known Exoplanets
<p>"By combining the size of the planets with their mass, something we can measure with telescopes on Earth, we learn a lot about the composition of the planets and their evolution," says Isaak.</p><p>All these differences are, of course, very small, since the stars and planets observed are several light years away. In order to be able to measure them at all, any disturbance must be excluded.</p><p>That's the reason why such observations are best made using space-based telescopes rather than those on Earth. The Earth's atmosphere would simply get in the way. CHEOPS is designed to target planets that are larger than Earth and smaller than Neptune.</p>Will CHEOPS Find Aliens?
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjE5MTUzOS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyNDQ5NTcxNX0.lBqib6i7kz4pC-54HrMG8aARzD5bPKnP087bT1J6CWM/img.jpg?width=980" id="7e8bd" class="rm-shortcode" data-rm-shortcode-id="b0cd3b54bd1a7aa0e7a8367083f40733" data-rm-shortcode-name="rebelmouse-image" /><p>The mission will take three and a half years. But, this time, the question of all questions will not be answered.</p><p>"The question of whether we are alone in the universe is certainly one of the most fundamental questions ever," says Isaak. But CHEOPS will not get that far. "Other satellites have shown that there are planets beyond our solar system. So it is clear that there are exoplanets. What we want to show now is what these smaller rock planets are like and how they evolve."</p><p>After all, it should be possible to identify at least some planets on which extraterrestrial life is at least conceivable.</p><p>"What we are looking for now are the best planetary candidates for future exploration by other satellites such as the James Webb Space Telescope or by observatories [such as the European Southern Observatory (ESO)] in South America. From there, we can study the atmospheres of these candidates and search for molecules characteristic of the presence of life." </p>Modular Research Satellite Design
<p>In addition to the scientific findings that the CHEOPS mission will provide, the ESA looking for ways of making research satellites cheaper. The satellite developers have come up with new technologies for this purpose.</p><p>"Satellites are very expensive and very complex to build. And these programs always take a very long time," says Richard Southworth of the European Space Operations Centre (ESOC). He is responsible for controlling the CHEOPS satellite.</p><p>"With CHEOPS, the idea was to see if we could do it better, a little faster and less costly. We have tried to keep the probe relatively simple and above all to use parts that have flown on other missions before. These components will then be less expensive and more reliable because they have already been tested."</p><p>ESA also saves on the transport of the probe into space: CHEOPS flies on a Soyuz rocket as cargo. So the project shares the travel costs with another — in this case an Italian — satellite.</p><p>And even if the satellite is already in the sky, there is still an opportunity to reduce costs. The CHEOPS researchers use the flying telescope only 80 percent of the time. The rest of the time others can rent it for their own research. </p>Scrapping Already Firmly Scheduled

But what happens to CHEOPS when the project is finished?</p><p>"It's planned to operate for three and a half years," says satellite controller Southworth. "But the design of the satellite should ensure that we could also fly for five years if there is money and interest. In the end, we deactivate the satellite and initiate de-orbiting."</p><p>The satellite will first be switched into a passive mode so that it can no longer interfere with radio signals or other satellites.</p><p>"Finally, we will also make an orbit correction. This will lead to the satellite's safe return to Earth. That means CHEOPS won't become space debris in the long run."</p><p>In the end, the probe will burn and disintegrate when entering the earth's atmosphere.</p>

Footage from the Ohio State Highway Patrol on the second day of a fracking well blowout that new data reveals caused one of the largest methane leaks in U.S. history. FracTrackerVideos
In February 2018, a blowout at a fracked natural gas well in Belmont County, Ohio forced around 100 nearby residents to flee their homes, as The New York Times reported. Now, a study published in the Proceedings of the National Academy of Sciences Monday has revealed that the local incident had major implications for the global climate crisis.
<p>Researchers used satellite data to determine that the blowout caused one of the largest <a href="https://www.ecowatch.com/tag/methane" target="_self">methane</a> leaks in U.S. history. It released more methane in around 20 days than the oil and gas industries of France, Norway and the Netherlands do in a year, <a href="https://www.bloomberg.com/news/articles/2019-12-16/exxon-well-blast-causes-huge-methane-leak-in-ohio-study-shows" target="_blank">Bloomberg News reported</a>. The results raise questions about the ability of the oil and gas industry to control methane leaks.</p><p>"When I started working on methane, now about a decade ago, the standard line was: 'We've got it under control. We're managing it,'" study coauthor and <a href="https://www.edf.org/" target="_blank">Environmental Defense Fund</a> (EDF) scientist Dr. Steven Hamburg told The New York Times. "But in fact, they didn't have the data. They didn't have it under control, because they didn't understand what was actually happening. And you can't manage what you don't measure."</p>
<p>The research is one example of how satellites can help accurately measure the problem. The paper's Holland and U.S.-based authors used data from the spaceborne Tropospheric Monitoring Instrument (TROPOMI) to determine that the well leaked methane at a rate of about 120 metric tons per hour, double the rate of leakage from the largest ever methane leak in U.S. history, which took place in 2015 at a California oil and gas storage facility. The satellite measurements also estimated that the leak spewed 60 kilotons of methane in total into the atmosphere, <a href="https://www.stuff.co.nz/business/world/118263402/seen-from-space-us-gas-well-blowout-created-a-methane-superemitter" target="_blank">Stuff.co.nz reported</a>. That's five times the amount estimated by <a href="https://www.ecowatch.com/tag/exxon" target="_self">ExxonMobil</a>, whose subsidiary XTO Energy owns the well.</p><p>"We deeply regret this incident occurred and are committed to identifying and managing risks associated with our activities to prevent recurrence," ExxonMobil spokeswoman Julie King told Stuff.co.nz in an email. "We are eager to learn more about their study. ExxonMobil is working with government laboratories, universities, NGOs and other industry participants to identify the most cost-effective and best-performing technology, including satellites, that can be adopted by all producers to detect, repair and accurately measure methane."</p>
<p>The study also raises questions about the climate safety of <a href="https://www.ecowatch.com/fracking/" target="_self">fracking</a> and natural gas. While burning natural gas only emits half the greenhouse gases that burning <a href="https://www.ecowatch.com/tag/coal" target="_self">coal </a>does, methane is as much as 25 times more powerful than carbon dioxide. Methane leaks can therefore undermine the relative advantage of gas when it comes to lowering emissions.</p><p>The study's authors wrote that satellite measurements can help keep track of methane leaks that might otherwise be missed in calculating greenhouse gas emissions. Environmental groups are also increasingly embracing satellites as a tool. The EDF is even partnering with an aerospace company to build and <a href="https://www.ecowatch.com/methane-climate-crisis-2641609524.html?rebelltitem=2#rebelltitem2" target="_self">launch a satellite</a> dedicated to finding and monitoring methane leaks.</p><p>"We're entering a new era. With a single observation, a single overpass, we're able to see plumes of methane coming from large emission sources," satellite expert and study coauthor Ilse Aben told The New York Times. "That's something totally new that we were previously not able to do from space."</p>

For decades, Burt's Bees has been one of the leading names in cosmetic and skincare products developed with sustainability in mind. Not only do they create high-quality products from natural ingredients, but they're attentive to the ways in which their production, packaging, and distribution methods impact the world around them. For those who value environmental stewardship and wise corporate citizenship, Burt's Bees is iconic.
Perhaps it was only a matter of time before the company expanded its all-natural skincare and cosmetic line to include products that harness the potent, holistic effects of CBD. In this post, we'll offer a quick guide to the products included in the new Burt's Bees CBD line, as well as some further comments about the company as a whole.
<h2>Why CBD?</h2><p>First, it may be worth asking why all of this matters. What's the big deal about CBD, anyway?</p><p>CBD is short for cannabidiol, one of the most prevalent, active ingredients in the cannabis plant (marijuana). CBD has been linked with a <a data-linked-post="2648638251" href="https://www.ecowatch.com/organic-cbd-oil-2648638251.html" target="_blank">number of positive, holistic health effects</a>; in fact, it's been FDA-approved as a treatment for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5767492/" target="_blank">epilepsy and seizures</a>, while much anecdotal evidence positions it as an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2828614/" target="_blank">anti-inflammatory agent</a>.</p><p>Crucially, legally-available CBD products have little or no <em>THC</em>, which is the psychoactive ingredient in the marijuana plant; in other words, you can enjoy the therapeutic benefits of CBD without any risk of getting high.</p><h2>The Burt's Bees Story</h2><p>With that said, let's get back to Burt's Bees.</p><p>The company was founded in the early 1980s by Burt Shavitz and Roxanne Quimby, veterans of the art community who sought refuge and contemplation in the prairies of Maine. Eventually, their interests led them to beekeeping, and into developing lip and skincare products developed from homegrown beeswax.</p><p>From the very beginning, their mission was to develop products that drew from the power of nature, while also taking seriously their responsibility to preserve, protect, and respect nature.</p><p><br/></p><p class="shortcode-media shortcode-media-rebelmouse-proxy-image">

</p><h3>Sustainability at Burt's Bees<br/></h3><p>There are a number of ways in which Burt's Bees continues to live out its commitment to sustainability to this day.</p><h3>All Ingredients Come from Nature</h3><p>The company strives for 100 percent natural ingredients in all of their products, and generally comes pretty close. (Their skincare products are all 95 percent natural, at a bare minimum.) Everything they make is absent <a data-linked-post="2628289611" href="https://www.ecowatch.com/chemicals-in-cosmetics-damage-childrens-health-2628289611.html" target="_blank">parabens</a> and other concerning, artificial chemicals.</p><h3>No Products are Tested on Animals</h3><p>Burt's Bees products are all "<a data-linked-post="1881939362" href="https://www.ecowatch.com/13-eco-labels-to-look-for-when-shopping-1881939362.html" target="_blank">Leaping Bunny Certified</a>." What this means is that they never test their products on animals, or ask any third parties to conduct animal testing on their behalf.</p><h3>Eco-Friendly Sourcing</h3><p>The company also demonstrates a responsible approach to sourcing, visiting all their ingredient harvesting sites to ensure a commitment to stewardship and sustainability.</p><h3>Environmentally Friendly Packaging</h3><p>All Burt's Bees products are completely recyclable. They avoid over-packaging, and their plastics are made up largely of recycled materials. </p><p>The bottom line: Burt's Bees is a company with serious eco-credentials… and that makes them a logical choice for expansion into the world of natural, sustainably sourced CBD.</p><h2>About Burt's Bees CBD Products</h2><p>Currently, Burt's Bees offers five products that are made with <a data-linked-post="2649092883" href="https://www.ecowatch.com/full-spectrum-cbd-oil-2649092883.html" target="_blank">full spectrum CBD</a>. What this means is that their CBD includes trace elements of all parts of the plant, including other <a data-linked-post="2649030477" href="https://www.ecowatch.com/cannabis-terpenes-2649030477.html" target="_blank">cannabinoids and terpenes</a>. According to many CBD experts, this provides a more potent and effective product overall. </p><p>All of the company's CBD ingredients are sourced from hemp that's grown and harvested in Colorado, using the most sustainable, organic agricultural practices. </p><p>Another important note about Burt's Bees CBD products: All of them are rigorously third-party tested. Independent lab results are key whenever you buy CBD, because it allows you to get a good sense of the purity, quality, and potency of what you're buying. You can get batch-specific test results for any Burt's Bees product simply by visiting their website.</p><h2>So, what about the specific products in the Burt's Bees CBD line?</h2>
<h2>Sustainably Sourced CBD Products</h2><p>It's important to emphasize that <em>all </em>of these products are made with transparently sourced CBD ingredients, as well as the company's usual high standards of eco-friendly packaging. In other words, this is a great opportunity to enjoy some of the benefits of CBD skincare, with all the sustainability and sound environmental stewardship that Burt's Bees is known for.</p><p>We're happy to recommend these products as good entry points into CBD skincare. Always remember, when shopping for CBD products, look for third party test results and transparency about sourcing information, all of which Burt's Bees makes readily available.</p><p><em><strong>Josh Hurst</strong> </em><em>is a journalist, critic, and essayist.

Brazil's National Space Research Institute (INPE) resumed releasing deforestation data after nearly a month-long hiatus that followed the firing of the agency's director on Aug. 2.
<p>The newly released data, which is based on short-term deforestation alerts, estimates that nearly 1,400 square kilometers of forest were cleared in the Brazilian Amazon between Aug. 1 and Aug. 26, 2019. That rate is running well ahead of last August when 520 square kilometers were cleared during the whole month.</p><p><br/></p><p class="shortcode-media shortcode-media-rebelmouse-image">

Fires
<p>INPE reported an increase in burn scars in the Amazon, rising from 794 square kilometers last August to 1,259 square kilometers for the first 26 days of last month. Burn scars are not necessarily representative of recent deforestation however: most burn scars occur in agricultural lands, pasture, scrub, and degraded forest areas.<br></p><p>INPE also updated its fire data, counting more than 30,000 fire hotspots in Amazonia for the month of August 2019, nearly triple the 10,421 registered last August. INPE should be releasing its estimate of the area burned in August soon.</p>From Your Site Articles

The glaciers of the Himalayas are melting twice as fast as they were in the year 2000, a study published Wednesday in Science Advances found.
<p>The researchers assembled the most detailed look to date at the last 40 years of Himalayan ice loss to date, combining contemporary satellite information with data from declassified U.S. spy satellites. They found that average ice-loss per year had doubled between the periods 1975 to 2000 and 2000 to 2016, and that the glaciers had lost more than 25 percent of their ice in the study period, <a href="https://www.theguardian.com/environment/2019/jun/19/himalayan-glacier-melting-doubled-since-2000-scientists-reveal?CMP=twt_a-environment_b-gdneco&fbclid=IwAR0xz9hyziABtJ2seriMEYLLFGyuQpezUuZRXKrsaXjXedTuaR9QtXsL3AI" target="_blank">The Guardian reported</a>.</p>

Researchers with the European Space Agency (ESA) have mapped in stunning detail the extensive retreat of South America's Patagonian ice fields, where some glaciers are melting at the highest rates on Earth and contribute to global sea level rise.
In a report this week, ESA revealed that between the years 2011 and 2017, Patagonia's ice fields receded at a rate of more than 21 gigatonnes (Gt)—21 billion metric tons—a year, the equivalent to adding 0.06 millimeters to global sea level.
<p>
During that six-year period, the team observed "widespread thinning of ice, particularly in the northern part of the Patagonian ice fields," said Luca Foresta, from the University of Edinburgh, in a statement.
</p><p>
<span></span>"For example, the Jorge Montt glacier, which flows down to the ocean, retreated 2.5 kilometers and lost about 2.2 Gt of ice a year, and the Upsala glacier, which terminates at a lake, lost 2.68 Gt a year," Foresta said.
</p><p>
"In contrast, however, Pio XI, the largest glacier in South America, advanced and gained mass at a rate of about 0.67 Gt a year."
</p><p>
The scientists gathered this information using a novel technique called "<a href="https://www.esa.int/spaceinimages/Images/2018/05/Swath_processing" target="_blank">swath processing</a>" of data from ESA's CryoSat satellite, which monitors ice volume.
</p><p>
This new method, detailed in a
<a href="https://www.sciencedirect.com/science/article/pii/S0034425718301421" target="_blank">paper</a> published last month in the journal Remote Sensing of Environment, allows whole swaths, rather than single points, of elevations to be computed, thus yielding more detail on the changing nature of glacial ice.

The study authors noted that Patagonian ice fields have thinned rapidly in recent years. Its ongoing melting has contributed about 15 percent to the total mass loss from glaciers and ice caps in the first decade of this century.
</p><p>
"This is because the weather is relatively warm and these glaciers typically terminate in fjords and lakes, exacerbating surface melting and causing them to flow faster and lose ice as icebergs at their margins," ESA explained in a report.
</p><p>
"There is a clear need to monitor and understand glacial dynamics, not only in Patagonia but globally," ESA said.

In an effort to understand how climate change is altering the carbon cycle, a project between the University of Oklahoma and NASA is headed to space. Orbiting 22,000 miles above Earth's surface, this host of instruments will track carbon as it flows through the Earth delivering real-time data and helping scientists quantify just how much humans are affecting the planet.
<p>The carbon cycle is an inconspicuous, but vital, system in all ecosystems, including marine habitats, forests and even deserts. All plants need carbon to complete photosynthesis, and when they die, that carbon is either released back into the atmosphere, or buried deep under ground to create fossil fuels over thousands of years. As we are seeing today, the carbon cycle plays a huge role in temperature fluctuation and weather patterns and unfortunately, the more carbon we trap in the atmosphere, the more unpredictable these fluctuations become. </p><p>The University of Oklahoma is calling the mission the Earth Venture Mission, and the payload (the part that will attach to one of Earth's satellites) is called the Geostationary Carbon Observatory, or <a href="https://www.nasa.gov/press-release/nasa-announces-first-geostationary-vegetation-atmospheric-carbon-mission" target="_blank">GeoCarb</a>. Although it may seem like an extreme measure to take, scientists believe it is necessary. The increase of carbon in the atmosphere well surpassed the <a href="http://www.ecowatch.com/noaa-carbon-dioxide-levels-2321635970.html" target="_blank">point of no return</a>—or carbon threshold—in 2016 and has continued to steadily rise above 400 parts per million. This is rapid warming compared to the 280 ppm that persisted for thousands of years before the industrial revolution. Scientists say we've reached a state of unknown, and launching the GeoCarb is our best bet in being able to predict where we go from here. </p><p class="shortcode-media shortcode-media-rebelmouse-image"><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy85ODEzODY2L29yaWdpbi5wbmciLCJleHBpcmVzX2F0IjoxNjQwNjA4MzI4fQ.n6TvWocnbg_ETqVVhpTbX4J39_9ndT-4BfcLq9faaq8/img.png?width=980" id="6f7c5" class="rm-shortcode" data-rm-shortcode-id="0ce4ac023b9895cc1456b8671aaf9e17" data-rm-shortcode-name="rebelmouse-image"><small class="image-media media-caption" placeholder="Add Photo Caption...">From 1958 to 2017, carbon has been shy rocketing. </small><small class="image-media media-photo-credit" placeholder="add photo credit..."> Scripps Institution of Oceanography</small></p><p>The GeoCarb will rotate in tandem with Earth at 85 degrees west longitude where it will be able to record human activity in developed nations from urbanized areas to agricultural lands. It will take measurements of carbon dioxide, methane and carbon monoxide once or even twice daily. It will also measure solar induced fluorescence, which is the light that plants can't absorb and is therefore repelled from Earth. This measurement will be closely tied to the rate of photosynthesis, and will help map out where carbon sinks exist. The map will also help scientists understand where there is a natural release in carbon, such as when a plant dies and decays, versus when human-induced carbon is released. It will be the first time scientists are able to watch the Western Hemisphere breathe in and out every day.</p><p>"Knowing what fraction of these changes is caused by human activities is important for understanding our impact on the planet, and observing and measuring it is essential to any conversation about strategies for reducing CO2 emissions," Berrien Moore, director of the National Weather Center at the University of Oklahoma, told <a href="https://theconversation.com/watching-the-planet-breathe-studying-earths-carbon-cycle-from-space-72344" target="_blank">The Conversation</a>.</p><p>"These observations, along with direct measurements of photosynthetic activity from SIF observations, will raise our understanding of the carbon cycle to a new level." <br></p>
