Pi Day Challenge: Solve Stellar Math Problems With NASA

March 10, 2023
Pi Day is the annual tribute to the mathematical constant pi, whose infinite number of decimals is usually rounded to 3.14. So what better day to celebrate than March 14? To find pi, aka the Greek letter π, you simply divide any circle’s circumference by its diameter. It’s a ratio that’s indispensable to NASA missions studying Earth, Mars, and beyond. This Pi Day marks the 10th year that…

NASA Space Mission Takes Stock of Carbon Dioxide Emissions by Countries

March 8, 2023
A NASA Earth-observing satellite has helped researchers track carbon dioxide emissions for more than 100 countries around the world. The pilot project offers a powerful new look at the carbon dioxide being emitted in these countries and how much of it is removed from the atmosphere by forests and other carbon-absorbing “sinks” within their borders. The findings demonstrate how space-based…

Removing Traces of Life in Lab Helps NASA Scientists Study Its Origins

March 1, 2023
In the Origins and Habitability Lab at NASA’s Jet Propulsion Laboratory, you can find a world in a test tube – specifically, a simplified simulation of early Earth. By re-creating the conditions that would have been found on our planet roughly 4 billion years ago, scientists can narrow down the possible chemical reactions that could have taken place then – including those that may have been…

NASA’s Perseverance Rover Set to Begin Third Year at Jezero Crater

February 18, 2023
NASA’s Perseverance rover will celebrate its second anniversary on the surface of Mars Saturday, Feb. 18. Since arriving at Jezero Crater in 2021, the six-wheeled, nuclear-powered rover has been examining geologic features and collecting samples of the Red Planet that are central to the first step of the NASA-ESA (European Space Agency) Mars Sample Return campaign. Scientists want to study…
