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 www.MethaneSAT.org 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.

हिंदी आलोचना जैसे पिछड़ चुके अनुशासन की जगह हिंदी वैचारिकी का विकास जरूरी

- प्रमोद रंजन*   भारतीय राजनीति में सांप्रदायिक व प्रतिक्रियावादी ताकतों को सत्ता तक पहुंचाने में हिंदी पट्टी का सबसे बड़ा योगदान है। इसका मुख्य कारण हिंदी-पट्टी में कार्यरत समाजवादी व जनपक्षधर हिरावल दस्ते का विचारहीन, अनैतिक और  प्रतिक्रियावादी होते जाना है। अगर हम उपरोक्त बातों को स्वीकार करते हैं, तो कुछ रोचक निष्कर्ष निकलते हैं। हिंदी-जनता और उसके हिरावल दस्ते को विचारहीन और प्रतिक्रियावादी बनने से रोकने की मुख्य ज़िम्मेदारी किसकी थी?

Under Modi, democracy is regressing and economy is also growing slowly

By Avyaan Sharma*   India is "the largest democracy in the world", but now its democracy is regressing and its economy is also growing slowly. What has PM Modi's ten years in power brought us? Unemployment remains high. Joblessness is particularly high among India's youth - with those aged 15 to 29 making up a staggering 83% of all unemployed people in India, according to the "India Employment Report 2024", published last month by the International Labour Organisation (ILO) and the Institute of Human Development (IHD). The BJP-led government did not provide jobs to two crore youth in a year as was promised by Modi in the run up to the 2014 general elections.

नफरती बातें: मुसलमानों में असुरक्षा का भाव बढ़ रहा है, वे अपने मोहल्लों में सिमट रहे हैं

- राम पुनियानी*  भारत पर पिछले 10 सालों से हिन्दू राष्ट्रवादी भारतीय जनता पार्टी (भाजपा) राज कर रही है. भाजपा आरएसएस परिवार की सदस्य है और आरएसएस का लक्ष्य है हिन्दू राष्ट्र का निर्माण. आरएसएस से जुड़ी सैंकड़ों संस्थाएँ हैं. उसके लाखों, बल्कि शायद, करोड़ों स्वयंसेवक हैं. इसके अलावा कई हजार वरिष्ठ कार्यकर्ता हैं जिन्हें प्रचारक कहा जाता है. भाजपा के सत्ता में आने के बाद से आरएसएस दुगनी गति से हिन्दू राष्ट्र के निर्माण के अपने एजेण्डे को पूरा करने में जुट गया है. यदि भाजपा को चुनावों में लगातार सफलता हासिल हो रही है तो उसका कारण है देश में साम्प्रदायिकता और साम्प्रदायिक मुद्दों का बढ़ता बोलबाला. इनमें से कुछ हैं राम मंदिर, गौमांस और गोवध एवं लव जिहाद. 

Laxmanpur Bathe massacre: Perfect example of proto-fascist Brahmanical social order

By Harsh Thakor  The massacre at Laxmanpur-Bathe of Jehanabad in Bihar on the night of 1 December in 1997 was a landmark event with distinguishing features .The genocide rightly shook the conscience of the nation in the 50th year of Indian independence. The scale of the carnage was unparalleled in any caste massacre. It was a perfect manifestation of how in essence the so called neo-liberal state was in essence most autocratic. 

रैंकिंग: अधिकांश भारतीय विश्वविद्यालयों का स्तर बहुत गिरा, इस साल भी यह गिरवाट जारी

- प्रमोद रंजन*  अप्रैल, 2024 में भारतीय विश्वविद्यालयों की अंतर्राष्ट्रीय स्तर पर उच्च रैंकिंग की चर्चा रही। मीडिया ने इसका उत्सव मनाया। लेकिन स्थिति इसके विपरीत है। वैश्विक विश्वविद्यालय रैंकिग में अच्छा स्थान मिलने की खबरें, कुछ संस्थानों को इक्का-दुक्का विषयों में मिले रैंक के आधार पर चुनिंदा ढंग से प्रकाशित की गईं थीं। वास्तविकता यह है कि हाल के वर्षों में हमारे अधिकांश विश्वविद्यालयों का स्तर बहुत गिर गया है। इस साल भी यह गिरवाट जारी रही है।

दाँव उल्टा पड़ा: राहुल गांधी के रूप में हम एक साधारण इंसान को नायक होते देख रहे हैं

-  अमिता नीरव  संघ औऱ बीजेपी ने राहुल गाँधी पर जो सोचकर ‘इन्वेस्ट’ किया था, उसके परिणाम गंभीर रूप से नुकसानदेह आ रहे हैं। ये थोड़ी अटपटी बात लग सकती है, लेकिन सोचिएगा कि संघ और बीजेपी ने राहुल गाँधी को जितना गंभीरता से लिया, उनकी संभावनाओं को लेकर वे जितना श्योर थे, उतना तो खुद राहुल और कांग्रेस भी नहीं थी।
