Seeing the COVID-19 Pandemic from Space

Economic and social shutdowns in response to the COVID-19 pandemic have led to noticeable changes in Earth’s environment, at least for the short term. NASA researchers are using satellite and ground-based observations to track these impacts on our airlandwater, and climate. These datasets have been collected in a free and openly available online dashboard.

The NASA COVID-19 Dashboard features data collected by Earth-observing satellites, instruments aboard the International Space Station, and sensitive ground-based networks. The global maps are searchable by several categories of observable change, including economic indicators, such as shipping and construction activity, and environmental factors, such as water quality and climate variations. Investigate the data layers yourself or take a guided tour of how NASA Earth scientists are studying – and learning about – the pandemic’s effects on the Earth system.

NASA scientists use many different tools, datasets, and methods to investigate COVID-related changes in the Earth system. Comparing complementary datasets on the dashboard helps reveal a deeper story of how the environment is changing due to COVID-related shutdowns.

Thermal data from the joint NASA-U.S. Geological Survey Landsat satellite show decreases in the urban heat island effect, a phenomenon where urban areas are significantly warmer than adjacent rural areas, during the pandemic. The left image shows temperatures over San Francisco in April 2018, while the right image shows temperatures over San Francisco in April 2020. Scientists found that large parking lots, highway corridors, and commercial rooftops were on average 10-15 degrees Fahrenheit (5-8 degrees Celsius) cooler from March to May 2020, compared to previous years.

For example, scientists at NASA’s Ames Research Center discovered that emptier parking lots near closed, non-essential businesses, in combination with cleaner air from less surface transportation, meant that heat from the sun radiating off dark asphalt and cement surfaces did not stay trapped near the ground as long. Instead, heat dissipated quickly, cooling the urban environment. Comparing the data to pre-pandemic years, scientists found that large parking lots, highway corridors, and commercial rooftops were, on average, 10-15 degrees Fahrenheit (about 5-8 degrees Celsius) cooler from March to May 2020.

The NASA COVID-19 Dashboard will be updated with more data and discoveries throughout the pandemic and beyond.

Elon Musk reveals residents in his 2050 Mars city will live in glass domes – and ‘terraform’ the planet to be like Earth

LIFE ON MARS

ELON Musk has plans for humans to live in glass domes on Mars.

Understandbly, a lot of people have questions about how Musk proposes all these people survive.

Terraforming would mean creating the right environment outside the domes so plants could grow just like on Earth and there would be an oxygen supply.

When told that terraforming would be unlikely to work with current technologies Musk had another response.

He said: “Terraforming will be too slow to be relevant in our lifetime. However, we can establish a human base there in our lifetime.

“At least a future spacefaring civilization – discovering our ruins – will be impressed humans got that far.”

Musk has previously admitted that getting to Mars in his SpaceX rockets is the easy part but creating a city there will be tricky.

Musk has previously outlined plans for a Martian colony established by his rocket company, SpaceX. Pictured is an artist impression of the colony with a SpaceX Starship rocket in the background

A number of studies have concluded that terraforming the entire planet of Mars and changing its atmosphere may not be possible even if all the ice caps were melted to release CO2.

Musk wants a Starship rocket to make the journey to Mars as early as 2021.

During the Satellite 2020 conference earlier this year, Musk said: “If we don’t improve our pace of progress, I’m definitely going to be dead before we go to Mars.”

If his 2050 ambition becomes a reality, Musk will be 79 when one million humans are living in his proposed domes on Mars.

What is SpaceX?

Here’s what you need to know…

SpaceX is a cash-flushed rocket company that wants to take man to Mars.

It was set up by eccentric billionaire Elon Musk in 2002 and is based in Hawthorne, California.

SpaceX’s first aim was to build rockets that could autonomously land back on Earth and be re-used.

Musk hoped the technology would make flying and operating space flights far cheaper.

SpaceX currently uses its reusable rockets to fly cargo to the International Space Station for Nasa.

It also carries satellites and other space tech into orbit for various international governments and companies.

The company took astronauts up to the ISS for the first time in 2020.

Other future missions involve carrying tourists and astronauts to the Moon.

Musk has repeatedly said he believes humanity must colonise Mars to save itself from extinction.

He plans to get a SpaceX rocket to the Red Planet sometime in the 2030s.

Could these sightings and conspiracy theories prove that aliens do exist?

In other space news, human cremated ashes are to be sent to the Moon next year as part of a commercial burial service piggybacking on a Nasa lunar mission.

Wars could be settled in space in the future, a top RAF chief has warned.

And, the first burst of cosmic radio waves to be detected within our galaxy is repeating, according to scientists.

Elon tells us what homes would look like. Astronauts have been eating space food for decades, but that has come from earth.? What will they eat in Mars? How will they grow it? What are the health implications?

Interfacing Humans and Technology – Elon Musk

We are already cyborgs | Elon Musk | Code Conference 2016

Elon Musk – Cyborgs
Shidonna Raven Garden and Cook

Elon Musk is the CEO of Space X and Tesla Motors. Space X has begun commercial space travel transportation and recently returned a group of Astronauts from space splashing them into the Gulf of Mexico. He is by far one of the people on the cutting edge of space and technology not to mention engineering and other talents. Musk also began many successful and well known companies such as PayPal. As one thinks about medical devices and the concept of cyborgs, one can see how the current science and medical trend of interfacing humans and technology. How do we see this in our everyday lives? How do we see this occurring in our doctors offices? How do we see this in our interactions with technology and technological advances? What if you became too slow to compete with robots or Ai (artificial technology) on a job? Would you interface with technology to become more competitive? What are the health implications of doing so? Share your comments with the community by positing your comments below.

Commercial Space Travel & Space Food

Soviet, Yuri Gagarin was the first man in space April 12, 1961. Fast forward to today, Space X along with many other companies have gone full speed ahead into commercial space travel. Masters of history and archaeology will tell you that real life typically follows art. If that is the case, perhaps Star Trek is not to far off. Have you ever tasted space food? Do you ever think you will taste space food in your life time? What do you think space gardens and farms will look like? Share your comments with the community by positing below.
