SpaceX rocket propels MethaneSAT into orbit on new mission to protect climate

By Jag Jivan

First satellite developed by an environmental non-profit will see methane emissions others can’t, paving the way for heightened accountability and faster reductions.
Just after 4:00pm Pacific Time March 4  MethaneSAT safely detached from SpaceX Transporter-10 which carried the emissions monitor to space. The groundbreaking satellite is designed to help protect the Earth’s climate by accelerating reductions of a powerful greenhouse pollutant, focusing first on oil and gas operators, a major industrial source of methane emissions.
Developed by a subsidiary of the global non-profit Environmental Defense Fund, MethaneSAT will see and quantify total methane emissions over wide areas that other satellites can’t and identify large emitters in places they aren’t looking. Data from MethaneSAT will enable both companies and regulators to track emissions, and give stakeholders – citizens, governments and investors – free, near-real time access to the data, and the unprecedented ability to compare the results against emission goals and obligations.
“Cutting methane pollution from fossil fuel operations, agriculture and other sectors is the single fastest way to slow the rate of warming as we continue to decarbonize our energy systems,” said EDF President Fred Krupp. “To do that requires comprehensive data on this pollution on a global scale. MethaneSAT will show us the full scope of the opportunity by tracking emissions to their source.”
Krupp announced MethaneSAT in a 2018 TED Talk as part of the TED Audacious Project. EDF has been a global leader in methane science and solutions for more than a decade, putting the problem on the map by organizing a pioneering series of 16 independent studies that showed methane emissions across the U.S. oil and gas supply chain were 60% higher than EPA estimates at the time. MethaneSAT is a direct outgrowth of these efforts.
“MethaneSAT’s superpower is the ability to precisely measure methane levels with high resolution over wide areas, including smaller, diffuse sources that account for most emissions in many regions,” said Steven Hamburg, EDF Chief Scientist and MethaneSAT project leader. “Knowing how much methane is coming from where and how the rates are changing is essential.”
Circling the Earth 15 times a day, MethaneSAT will measure changes in methane concentrations as small as three parts per billion. High sensitivity together with high resolution and a wide field of view will enable MethaneSAT to see the whole emissions picture (see more detail here).
These unique capabilities usher in a new era of transparency for the industry. Interactive emissions data will be available to anyone directly from and on Google Earth Engine, a premier geospatial data platform used by over 100,000 experts and analysts.
MethaneSAT was made possible entirely by the support of EDF donors and our partnership with the Government of New Zealand. Among the largest contributors to MethaneSAT are the Bezos Earth Fund, Arnold Ventures, the Robertson Foundation and the TED Audacious Project.
“Methane emissions have been overlooked and hard to detect for far too long,” said Dr. Kelly Levin, Chief of Science, Data and Systems Change at the Bezos Earth Fund. “MethaneSAT changes the equation, putting science and data front and center. From the sky, it can see what others can’t, helping good actors and holding bad actors accountable. The Bezos Earth Fund is proud to be a partner in this adventure.”
In December, EDF joined with Bloomberg Philanthropies, the International Energy Agency, RMI and the UN Environment Programme’s International Methane Emission Observatory on a new, first-of-its-kind initiative to hold companies and governments more accountable for their methane management.
“You can’t manage what you can’t measure, and that’s certainly true when it comes to cutting methane, one of the biggest drivers of climate change,” said Michael R. Bloomberg, UN Secretary-General's Special Envoy on Climate Ambition and Solutions and Founder of Bloomberg LP and Bloomberg Philanthropies. “Data from this satellite will help us to better measure methane emissions and target their sources, bringing more transparency to the problem, giving companies and investors the information they need to take action, and empowering the public to hold people accountable.”
In addition to identifying emission sources and rates for a given region, MethaneSAT will make it possible to compare emission loss rates across major oil and gas regions worldwide and performance over time. Analytics developed specially for the mission will trace those emissions back to their sources within those target regions.
“We have consistently seen the power of strong data to win robust regulatory safeguards and better operating practices in the industry. Good science lays the groundwork for better decisions,” said Mark Brownstein, EDF Senior Vice President, Energy Transition.
In January the Biden Administration proposed rules for a fee on excess methane emissions, which will require accurate emissions reporting. European legislation agreed to in November charts a pathway toward requiring empirical emissions data from gas importers, while Japan and Korea – two of the largest LNG buyers – have launched plans to begin requiring emissions data from suppliers.
As methane standards are incorporated into national policy and trade agreements, MethaneSAT will help ensure targets are being met, and make clear where claimed reductions fall short.
Over 150 countries have signed the Global Methane Pledge to cut their collective methane emissions at least 30 percent from 2020 levels by 2030. At COP 28, over 50 companies announced the Oil & Gas Decarbonization Charter, committing to virtually eliminate methane emissions and routine flaring.
In addition to parent organization EDF, MethaneSAT partners include Harvard University’s School of Engineering and Applied Sciences, the Smithsonian Astrophysical Observatory, and the New Zealand Space Agency. The combined mission team has over 70 experts worldwide with experience in spaceflight, remote sensing, and data analytics.
The satellite was built in Colorado, USA, by the Space & Mission Systems unit of BAE Systems, Inc. (formerly Ball Aerospace) and Blue Canyon Technologies.



A Hindu alternative to Valentine's Day? 'Shiv-Parvati was first love marriage in Universe'

By Rajiv Shah*   The other day, I was searching on Google a quote on Maha Shivratri which I wanted to send to someone, a confirmed Shiv Bhakt, quite close to me -- with an underlying message to act positively instead of being negative. On top of the search, I chanced upon an article in, imagine!, a Nashik Corporation site which offered me something very unusual.

'28% rise in sedition cases': Top global NGO alliance rates India's civil space 'repressed'

By Rajiv Shah Rating India's civic space as repressed , Civicus, a global civil society alliance, in its new report submitted to the UN Human Rights Committee (UNHRC) on the state of civic space in the country has said that the use of sedition law against the Modi government’s critics continues. "Under the government of Prime Minister Narendra Modi, sedition cases have increased by 28 per cent with over 500 cases against more than 7,000 people", it says.

'Anti-poor stand': Even British wouldn't reduce Railways' sleeper and general coaches

By Anandi Pandey, Sandeep Pandey*  Probably even the British, who introduced railways in India, would not have done what the Bhartiya Janata Party government is doing. The number of Sleeper and General class coaches in various trains are surreptitiously and ominously disappearing accompanied by a simultaneous increase in Air Conditioned coaches. In the characteristic style of BJP government there was no discussion or debate on this move by the Indian Railways either in the Parliament or outside of it. 

Swami Vivekananda's views on caste and sexuality were 'painfully' regressive

By Bhaskar Sur* Swami Vivekananda now belongs more to the modern Hindu mythology than reality.
