NASA is designing missions to help protect Earth from climate change

NASA will launch five satellites to create a 3D image of the Earth and study how climate change is fueling natural disasters

  • NASA will launch at least five satellites by 2029 to help the U.S. government better understand climate change and extreme weather 
  • The satellites will create a 3-D view of Earth, looking at everything from its bedrock to its atmosphere
  • The satellites will measure aerosols, rising sea levels, volcanoes, landslides and more 
  • ‘A whole of government, all hands-on-deck approach’ is being used, NASA Administrator Bill Nelson said 
  • According to a 2017 survey, the estimated the cost of each mission is between $300 million and $800 million 

NASA is developing a new satellite-centric program set to help the U.S. government better understand the effects of climate change and extreme weather events.

Known as the Earth System Observatory, at least five satellites will be launched through 2029 to create a 3-D view of the Earth, looking at everything from its bedrock to its atmosphere.

The satellites will look at a whole host of areas related to human activities and weather events, including aerosols, rising sea levels and the impact that climate change is having on food and agriculture.   

Measuring ice-sheet collapse, as well as earthquakes, volcanoes and landslides, are also a part of the mission. 

Assessing droughts and forecasting associated planning of water use for agriculture is also a part of the mission.

‘I’ve seen firsthand the impact of hurricanes made more intense and destructive by climate change, like Maria and Irma,’ NASA Administrator Sen. Bill Nelson said in a statement. ‘The Biden-Harris Administration’s response to climate change matches the magnitude of the threat: a whole of government, all hands-on-deck approach to meet this moment.’

Nelson continued: ‘Over the past three decades, much of what we’ve learned about the Earth’s changing climate is built on NASA satellite observations and research. NASA’s new Earth System Observatory will expand that work, providing the world with an unprecedented understanding of our Earth’s climate system, arming us with next-generation data critical to mitigating climate change, and protecting our communities in the face of natural disasters.’

NASA Administrator Bill Nelson said he became an ‘environmentalist’ after his stint as an astronaut

NASA said the Earth-focused missions will provide ‘key information’ for a multitude of events, such a fighting forest fires to dealing with natural disasters

The upcoming missions are part of a broader effort by the Biden administration to ‘enhance climate resilience,’ including providing additional money to FEMA, executive orders and strengthening the National Climate Task Force.    

The proposed missions follows the recommendations from the 2017 Earth Science Decadal Survey.

According to SpaceNews, the survey estimated the cost of each mission between $300 million and $800 million.  

Speaking with Axios, Nelson, a former astronaut on the Space Shuttle Columbia and Florida Senator, said that he shares the Biden administration’s urgency on climate change.

‘Now I’m in a position to try to help my friend, who is the President, and what he is trying to do, is to shape the reality of what is happening to our planet into the focus of people’s minds, that the Earth is in fact heating up, and we’d better get about the business of trying to do something about it,’ he told the news outlet.

‘Otherwise, you will continue to have more ferocious storms, and, and they will be larger.’  

Nelson added that he became an ‘environmentalist’ after his stint as an astronaut. 

Though the mission is still in the formulation phase, NASA said it is already working with the Indian Space Research Organization (ISRO).

The U.S. space agency may use the NASA-ISRO Synthetic Aperture Radar (NISAR) spacecraft as a pathfinder for the observatory. 


Global sea levels could rise as much as 1.2 metres (4 feet) by 2300 even if we meet the 2015 Paris climate goals, scientists have warned.

The long-term change will be driven by a thaw of ice from Greenland to Antarctica that is set to re-draw global coastlines.

Sea level rise threatens cities from Shanghai to London, to low-lying swathes of Florida or Bangladesh, and to entire nations such as the Maldives.

It is vital that we curb emissions as soon as possible to avoid an even greater rise, a German-led team of researchers said in a new report.

By 2300, the report projected that sea levels would gain by 0.7-1.2 metres, even if almost 200 nations fully meet goals under the 2015 Paris Agreement.

Targets set by the accords include cutting greenhouse gas emissions to net zero in the second half of this century.

Ocean levels will rise inexorably because heat-trapping industrial gases already emitted will linger in the atmosphere, melting more ice, it said.

In addition, water naturally expands as it warms above four degrees Celsius (39.2°F).

Every five years of delay beyond 2020 in peaking global emissions would mean an extra 20 centimetres (8 inches) of sea level rise by 2300.

‘Sea level is often communicated as a really slow process that you can’t do much about … but the next 30 years really matter,’ lead author Dr Matthias Mengel, of the Potsdam Institute for Climate Impact Research, in Potsdam, Germany, told Reuters.

None of the nearly 200 governments to sign the Paris Accords are on track to meet its pledges.
