Look Up… NASA Goes on the Offensive 

Today NASA is conducting an experiment that could save mankind one day in the future. 

Key Details

  • Tonight, NASA’s first technology designed to divert asteroid impacts is being tested. 
  • The test will see if targeting an asteroid with a collision can alter the trajectory of large interstellar objects and prevent them from striking the earth. 
  • “NASA’s Double Asteroid Redirection Test (DART), the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards, will impact its target asteroid—which poses no threat to Earth,” says NASA. 
  • “NASA controllers will deliberately crash their $330 million DART robot spacecraft into an asteroid. The half-tonne probe will be traveling at more than four miles a second when it strikes its target, Dimorphos, and will be destroyed,” says The Guardian. 
  • “The scene will play out nearly 7 million miles from Earth,” says Bloomberg. 
  • The European Space Agency is planning to send a probe to the impacted asteroid in 2024 to study the crater left by DART. 
  • The test will be broadcasted tonight starting at 6 pm eastern time from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.
  • NASA is currently tracking no serious life-threatening asteroids. 

Why it’s news

Asteroid impacts are very common, and Earth has experienced several major impacts in its history. An impact 66 million years ago was powerful enough to cause the mass extinction of the dinosaurs, some believe. 

“We know asteroids have hit us in the past. These impacts are a natural process and they are going to happen in the future. We would like to stop the worst of them,” says astronomer Alan Fitzsimmons. 

“Many smaller ones have yet to be detected, and they are still big enough to destroy entire cities and devastate large areas. We are mapping these smaller objects with increasing accuracy but we will have to be prepared to act if we find one that is on course for Earth. DART is the first step in ensuring we have the right technology to deal with the threat,” Fitzsimmons continues. 

Anti-asteroid technology has never been tested and a successful test would prove the viability of such technology to divert major life-threatening impacts and preserve the human race further in the future. 

Notable quote

“The DART mission is meant to prove out a technique in the field of planetary defense. Using algorithms previously used for military missile targeting, DART will impact Dimorphos, which is an orbiting moonlet of the larger asteroid Didymos… The plan is that the impact of the 1260-pound probe will cut Dimorphos’ orbital time around Didymos by a few minutes, thus demonstrating that humanity can affect the orbit of a body in space,” says Astronomy Magazine.

The Fake Chicken Is Real Food, FDA Says

Eat Just's cultivated chicken meat

Lab-grown cultivated meat has received Food and Drug Administration (FDA) clearance in the U.S., opening the door to a new meat sector.

Key Details

  • Cultivated meat company Eat Just has received tacit approval from the FDA to allow the consumption of its lab-grown chicken in the U.S.
  • The FDA’s decision means that it believes the company’s chicken is safe to consume.
  • While it received clearance from the FDA, Eat Just must get its second regulatory approval from the United States Department of Agriculture (USDA), which will inspect the company’s facilities and the meat it produces.
  • Eat Just is already selling cultivated chicken meat in Singapore, and the U.S. is the second country to move forward with regulatory approval for the lab-grown product.

Microsoft Boasts About Artificial Intelligence

artificial general intelligence

Microsoft now claims that OpenAI’s artificial intelligence (AI) chatbot ChatGPT is the beginning of artificial general intelligence (AGI). 

Key Details

  • In a recently released paper, Microsoft claimed that GPT-4, the latest model of ChatGPT, showed the beginning signs of AGI. 
  • AGI is a machine's ability to learn or understand at or above the level of human intelligence. 
  • The paper, “Sparks Of Artificial General Intelligence: Early Experiments With GPT-4,” contrasts with previous statements from OpenAI CEO Sam Altman, who has said GPT-4 is “still flawed, still limited,” Vice reports. 
  • A large part of the paper discusses the limitations of GPT-4, making it difficult to determine how close the language model really is to AGI. 
  • “GPT-4’s performance is strikingly close to human-level performance … we believe that it could reasonably be viewed as an early (yet still incomplete) version of an artificial general intelligence (AGI) system,” researchers wrote in the abstract.
  • Yet, in the introduction of the paper, researchers walked back this claim, saying, “Our claim that GPT-4 represents progress towards AGI does not mean that it is perfect at what it does, or that it comes close to being able to do anything that a human can do.”

CFOs Getting Giddy In the C-Suite Shuffle

CFO to CEO

More chief financial officers are pursuing the CEO role, but making the switch from one executive position to another may not always be smooth. 

Key Details

  • Last year, of the S&P 500 CFOs who made a job change, 33% became CEOs, compared to only 8.8% in 2021, Fortune reports. 
  • Sometimes, the transition from CFO to CEO can go smoothly. For example, Indra Nooyi successfully transitioned from CFO to CEO of PepsiCo in 2006.
  • CFOs often have to be pragmatic and data-driven, giving them the potential to become successful company leaders. 
  • But the path to CEO may not always be clear for a CFO. One important quality of a CEO is inspiring both employees and investors. CFOs do not typically have this same responsibility and may struggle to master the new challenge when stepping into the CEO position.
