Introduction:

The introduction of the answer is essential and should be restricted to 3-5 lines. Remember, a one-liner is not a standard introduction

MethaneSAT, a satellite engineered to track and quantify methane emissions on a global scale, was successfully launched aboard a SpaceX Falcon9 rocket from California. Orbiting the Earth 15 times daily, MethaneSAT will primarily focus on monitoring emissions from the oil and gas sector. It aims to gather extensive data to discern the sources of methane, ascertain responsibility for emissions, and assess whether these emissions are escalating or diminishing over time. The data collected by MethaneSAT will be publicly accessible in near real-time, facilitating prompt action by stakeholders and regulators to mitigate methane emissions.

It is the central part of the answer and one should understand the demand of the question to provide rich content

Key Features of MethaneSAT:

MethaneSAT is outfitted with a sophisticated high-resolution infrared sensor and a spectrometer, enabling it to fulfill crucial data requirements. It possesses the capability to detect minute variations in methane concentrations, reaching as low as three parts per billion in the atmosphere, thereby enabling the identification of smaller emission sources compared to preceding satellites. Additionally, MethaneSAT boasts a wide-camera view, spanning approximately 200 km by 200 km, facilitating the identification of larger emitters, colloquially referred to as "super emitters."

Need to Track and Quantify Methane Emissions:

Methane, despite being invisible, ranks as a potent greenhouse gas and stands as the second-largest contributor to global warming after carbon dioxide, responsible for 30% of global heating since the onset of the Industrial Revolution. With methane being 80 times more potent at trapping heat in the atmosphere than carbon dioxide over a 20-year period, its emissions pose significant environmental challenges. Furthermore, methane contributes to the formation of ground-level ozone, a hazardous gas linked to approximately one million premature deaths annually. Notably, the burning of fossil fuels constitutes a primary source, accounting for roughly 40% of human-induced methane emissions.

Conclusion:

The ending of the answer should be on a positive note and it should have a forward-looking approach. 

In 2021, over 150 nations committed to the Global Methane Pledge, pledging to reduce their collective methane emissions by at least 30% from 2020 levels by 2030. Moreover, more than fifty businesses pledged to substantially curtail routine flaring and methane emissions. MethaneSAT is poised to play a pivotal role in supporting these commitments by providing crucial data to aid in tracking progress and implementing measures to mitigate methane emissions effectively
