Signal Acquired! NASA’s Psyche Spacecraft Begins Its Epic Journey of Discovery

NASA’s Psyche spacecraft has begun its journey to the asteroid Psyche, believed to be an exposed planetary core in the asteroid belt. Through this mission, NASA aims to study the asteroid’s composition using advanced scientific instruments, providing insights into the early stages of planet formation and the evolution of the solar system.

The Psyche spacecraft, headed to the asteroid Psyche, has successfully initiated its solar-powered propulsion. During its six-year journey, it will utilize advanced optical communication via NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>NASA’s DSOC and is expected to orbit the asteroid by 2029.

Psyche mission controllers on Earth have received full acquisition of signal from the spacecraft, and the solar arrays are fully deployed. The spacecraft will be propelled by solar electric propulsion. The five-panel, cross-shaped solar arrays provide around 800 square feet of solar collecting surface and make the spacecraft about the size of a singles tennis court when fully deployed.

The solar arrays will produce more than 20 kilowatts of power when the spacecraft is near Earth, but they will generate just over 2 kilowatts of power – just a little more power than a hair dryer – when it reaches the asteroid Psyche, which is far away from the Sun. However, this will be more than enough power to meet the spacecraft’s needs on its journey, including running science instruments, telecommunications, equipment that controls the spacecraft’s temperature, and the spacecraft’s superefficient solar electric propulsion engines.

The solar propulsion system’s thrusters use electromagnetic fields to accelerate and push out charged atoms, or ions, of the neutral gas xenon. The expelled ions create the thrust that pushes Psyche through space and emit a blue glow. With no atmospheric drag to hold it back, the spacecraft will accelerate to speeds of up to 124,000 mph (200,000 kph) relative to Earth during its interplanetary journey to the asteroid belt.

At the beginning of its roughly six-year journey, the Psyche spacecraft will spend about 100 days in initial checkout to make sure everything is functioning properly, before firing up its thrusters. About 2.5 years after launch, the spacecraft will fly by MarsMars is the second smallest planet in our solar system and the fourth planet from the sun.

About 5.5 years from now, the cruise period will be ending, and around June 2029, the imagers on the spacecraft will be able to take photos of the asteroid Psyche. In August 2029, the spacecraft will drop into its first of 26 months of planned orbits around the metal-rich asteroid.

NASA’s DSOC (Deep Space Optical Communications) demonstration, carried by the Psyche spacecraft, will send and receive test data using an invisible near-infrared laser, which can transmit data at 10 to 100 times the bandwidth of conventional radio wave systems used on spacecraft today. DSOC will demonstrate operations for nearly two years after NASA’s Psyche mission launch while en route to its 2026 Mars flyby.

The Psyche mission is led by Arizona State University. NASA’s Jet Propulsion Laboratory is responsible for mission management, operations, and navigation.
