Nomads of the solar system, small objects like asteroids and comets wander among the planets. Messengers from the distant past, many of these small bodies include debris from the formation of the solar system and carry clues about its origins and the rise of life on Earth. NASA has visited some of them, recently reaching and then touching the asteroid Bennu to collect samples of rock unchanged for nearly 5 billion years.

Born from a swirling cloud of dust and gas some 4.6 billion years ago, our Sun seethes and boils like a living thing. It is the very center of our solar system, and large enough to encompass 1.3 million Earths. Explosions flash on its surface in colors of light beyond human vision and enormous loops of plasma stretch into space. The Sun’s influence extends out beyond the planets, creating a protective cocoon within the galaxy.

Episode two reveals why a space-based perspective is crucial to understanding how the food supply is distributed around the world. Satellites can reveal how many fields have been planted and how a crop is growing, providing a way to predict how much of a give commodity will be available at harvest. Governments and aid agencies around the world use this information to help them make informed decisions about food prices and trade and the possible need for aid long before harvest. The organizations that use NASA data include the United States Department of Agricultures Foreign Agricultural Service and USAID's Famine Early Warning System Network.

Using NASA’s Neil Gehrels Swift Observatory, which launched in 2004, scientists have discovered a black hole in a distant galaxy repeatedly nibbling on a Sun-like star. The object heralds a new era of Swift science made possible by a novel method for analyzing data from the satellite’s X-ray Telescope (XRT). When a star strays too close to a monster black hole, gravitational forces create intense tides that break the star apart into a stream of gas. The leading edge swings around the black hole, and the trailing edge escapes the system. These destructive episodes are called tidal disruption events. Astronomers see them as flares of multiwavelength light created when the debris collides with a disk of material already orbiting the black hole. Recently, astronomers have been investigating variations on this phenomena, which they call partial or repeating tidal disruptions. During these events, every time an orbiting star passes close to a black hole, the star bulges outward and sheds material, but survives. The process repeats until the star looses too much gas and finally breaks apart. The characteristics of the individual star and black hole system determine what kind of emission scientists observe, creating a wide array of behaviors to categorize. On June 22, 2022, XRT captured Swift J0230 for the first time. It lit up in a galaxy around 500 million light-years away in the northern constellation Triangulum. Swift’s XRT has observed nine additional outbursts from the same location roughly every few weeks. Scientists propose that Swift J0230 is a repeating tidal disruption of a Sun-like star orbiting a black hole with over 200,000 times the Sun’s mass. They estimate the star loses around three Earth masses of material on each pass. This system provides a bridge between other types of suspected repeating disruptions and allowed scientists to model how interactions between different star types and black hole sizes affect what we observe. Swift J0230’s discovery was possible thanks to a new, automated search of XRT observations called the Swift X-ray Transient Detector. After the instrument observes a portion of the sky, the data is transmitted to the ground, and the program compares it to previous XRT snapshots of the same spot. If that portion of the X-ray sky has changed, scientists get an alert. In the case of Swift J0230, astronomers were able to rapidly coordinate additional observations of the region.

We’re testing a new way of landing on Mars… by crashing into its surface. The Simplified High Impact Energy Landing Device (SHIELD) is a lander concept being tested at NASA’s Jet Propulsion Laboratory (JPL). It could one day provide a new way for low-cost missions to land on Mars. Rather than rely on parachutes or retrorockets, SHIELD would include a collapsible, accordion-like base to absorb the energy of a landing. A full-size prototype of the base was tested on Aug. 12, 2022. The prototype was hurled at the ground from the top of a nearly 90-foot-tall (27-meter-tall) drop tower at JPL. A steel plate ensured the impact was even harder than what would be experienced on Mars. The design worked: After crushing against the steel plate at 110 mph (177 kph), several electronic components inside the SHIELD prototype, including a smartphone, survived the impact.
