Lucy Spacecraft Will Slingshot Around Earth
NASA’s Lucy mission is heading to the Jupiter Trojans – two swarms of primitive asteroids trapped in Jupiter’s orbit that may hold clues to the formation of the planets. Lucy launched on October 16, 2021. After a year in orbit around the Sun, it is returning home on its launch anniversary for the first of three Earth gravity assists. On October 16, 2022, Lucy will fly by the Earth like a partner in a swing dance, boosting its speed and elongating its orbit around the Sun. At 7:04 am, Eastern Time, Lucy will make its closest approach at just 219 miles above the planet: lower than the International Space Station. This exceptionally close shave will increase its velocity by four-and-a-half miles per second, setting Lucy on track to gain even more speed when it returns to Earth for its second gravity assist in December 2024.

Ways to crash land on MARS!!
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.
