AI Observes Exoplanet, Space Probe That Will Almost Touch the Sun, and more - Today In Engineering 4

The video discusses four major scientific advancements. Google's machine learning technology assisted NASA in discovering new exoplanets by analyzing data from the Kepler Space Telescope. A new robotic hand, developed at the University of Utah, allows amputees to regain their sense of touch through neuroprosthetics. Researchers at Duke University have created a method to see through walls using microwaves without knowing the material. Lastly, NASA's Parker Solar Probe aims to study the sun's outer atmosphere, overcoming challenges like intense heat.

What role did Google's machine learning technology play in NASA's discovery of new exoplanets?

• It directly observed the exoplanets through telescopes.

• It helped sort through vast amounts of data to identify potential exoplanets.

• It programmed the Kepler Space Telescope to find exoplanets.

• It created a new type of telescope for exoplanet discovery.

How do neuroprosthetics help amputees with robotic hands?

• By using voice commands to operate the hand.

• By connecting the brain to a computer to control movements and sensations.

• By using external sensors to control the hand.

• By relying on muscle signals from the remaining limb.

What is the significance of the closed-loop system in the robotic hand experiment?

• It relies on muscle signals for operation.

• It uses external sensors to detect movement.

• It mimics biological feedback to enable touch and sensation.

• It allows the hand to be controlled by voice commands.

What is a key advantage of the new microwave technology developed at Duke University?

• It can see through walls without knowing the material beforehand.

• It requires knowledge of the wall material to function.

• It is primarily used for heating food.

• It uses a wide range of frequencies for better resolution.

Why is the new method of seeing through walls considered cost-effective?

• It requires expensive equipment.

• It uses a narrow band of microwave frequencies.

• It needs prior knowledge of the wall material.

• It uses a wide range of frequencies.

What is the primary goal of NASA's Parker Solar Probe mission?

• To collect data from the sun's core.

• To observe the sun from the same distance as Mercury.

• To study the sun by getting closer than any previous spacecraft.

• To land on the sun's surface.

What challenge does the Parker Solar Probe face when approaching the sun?

• Avoiding collisions with other spacecraft.

• Withstanding the intense heat from the sun.

• Navigating through the sun's core.

• Communicating with Earth from the sun's surface.
