The Road to October 2023: NASA’s Psyche Has an Updated Mission Plan

NASA’s Psyche mission, which will explore a metal-rich asteroid of the same name, is on track to launch in October 2023 after a one-year delay to complete critical testing. The launch period will open Oct. 5 and close Oct. 25. The asteroid, which lies in the outer portion of the main asteroid belt between Mars and Jupiter, may be the remains of a core of a planetesimal, a building block of a rocky planet.

Due to the new launch date, Psyche has a new mission plan, which includes a flyby of Mars for a gravity assist and arrival at the asteroid in August 2029. The mission then will enter its 26-month science phase, collecting observations and data as the spacecraft orbits the asteroid at different altitudes.

The redesigned flight plan gives the mission more flexibility in how the spacecraft uses its electric propulsion thrusters to reach the asteroid, move between orbits, and remain in orbit.

Unlike many other bodies in our solar system, the asteroid Psyche rotates on its side. Mission planners needed to take this unusual rotation into account as they mapped out the spacecraft’s observation orbits around the asteroid. Another challenge is that the spacecraft will reach Psyche at a different point in the asteroid’s orbit around the Sun than it would have in the previous mission plan. In the original plan, the spacecraft was to sequentially orbit the asteroid at four different altitudes, starting at the highest altitude (referred to as Orbit A) and working its way down to the lowest (Orbit D). In the new mission plan, Psyche will initially enter Orbit A, then descend to Orbit B1, then Orbit D, back out to Orbit C, and finally it will move out to Orbit B2 (the second portion of Orbit B).

This new orbital design ensures that imagers on the spacecraft will have the lighting they need during Orbits B1 and B2. The other orbits are designed to best enable the observations needed by Psyche’s Gamma Ray Neutron Spectrometer, magnetometer, and telecommunications system, which is used for the gravity science experiment.

Engineers and technicians now are completing the final verification and validation of the system-level elements of the fully integrated spacecraft. During this time, tests are performed on the spacecraft as well as in the mission’s three system test beds.

Later this spring, engineers will run a series of “day in the life” tests, when they use test beds to operate Psyche for five to seven days at a time with the same commands that they will use when it is in flight. They will run scenarios in which operations go as planned as well as when operations meet challenges.

The spacecraft is currently in a clean room at Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida. In June, the mission begins its final assembly, test, and launch operations, and engineers and technicians from NASA’s Jet Propulsion Laboratory in Southern California will return to Astrotech and work there until launch. Assembly of the spacecraft is complete except for the installation of the solar arrays and the imagers, which may be reinstalled before June. A final suite of tests will be run on the spacecraft, after which it will be fueled and then mated to the launch vehicle just prior to launch. Psyche will launch on a SpaceX Falcon Heavy rocket from Kennedy’s Launch Complex 39A. NASA’s Deep Space Optical Communications technology demonstration, intended to test high-data-rate laser communications, remains integrated into the spacecraft.

NASA’s Psyche spacecraft is shown in a clean room on Dec. 8, 2022, at Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. The spacecraft was powered on and connected to ground support equipment, enabling engineers and technicians to prepare it for launch in 2023. Teams working at Astrotech and at NASA’s Jet Propulsion Laboratory in Southern California continue to communicate with the spacecraft and monitor the health of its systems.

After a one-year delay to complete critical testing, the Psyche project is targeting an October 2023 launch on a SpaceX Falcon Heavy rocket. NASA’s Deep Space Optical Communications (DSOC) technology demonstration, testing high-data-rate laser communications, is integrated into the Psyche spacecraft. The silver-colored cylinder shown in the photo is the sun shade for DSOC, and the gold blanketing is the aperture cover for the DSOC payload.

The spacecraft’s target is a unique, metal-rich asteroid also named Psyche, which lies in the main asteroid belt between Mars and Jupiter. The asteroid may be the partial core of a planetesimal, a building block of rocky planets in our solar system. Researchers will study Psyche using a suite of instruments including multispectral cameras, Gamma Ray and neutron spectrometers (GRNS) and magnetometers. The GRNS and magnetometer sensors are visible in the photo as the tips of the two black protrusions at the far end of the spacecraft. Also, visible here is the high-gain antenna, which will enable the spacecraft to communicate with Earth.

The Psyche mission is led by Arizona State University. JPL, which is managed for NASA by Caltech in Pasadena, California, is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies in Palo Alto, California, is providing the high-power solar electric propulsion spacecraft chassis. DSOC is managed by JPL for the Technology Demonstration Missions program within NASA’s Space Technology Mission Directorate and the Space Communications and Navigation (SCaN) program within the agency’s Space Operations Mission Directorate. NASA’s Launch Services Program, based at the Kennedy Space Center, is managing the launch service. Psyche is part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama.

Board Begins Review of NASA’s Psyche Mission

On July 19, Psyche’s independent review board met for the first time.

The focus is on understanding technical issues that led to the delay, how the risk of delay was or was not understood and communicated within the project, as well as to those charged with oversight of the mission at JPL in a timely manner, and the work required to ensure that Psyche is ready for a potential future opportunity.

The board’s objectives are to:

  • Study any and all issues that contributed to the launch delay, including the lack of visibility of the problems to management, standing review board, technical authorities, etc. or through standard life cycle reviews.
  • Identify when the problems began arising, why there was a lack of visibility, and determine if there were missed opportunities to take action earlier to possibly prevent the launch delay or prevent shipping to KSC and preparations for launch.
  • Identify and raise other issues that might be crucial for mission success not yet recognized by the team.
  • Identify specific corrective actions to prevent future reoccurrence of identified issues both in the Psyche replan and in other missions.
  • Identify any additional technical work the board believes is required to be completed for launch readiness.
  • Identify lessons learned associated with the acquisition strategy of a commercial bus for future NASA deep space missions.

The board is expected to brief their findings to NASA and JPL leadership in late September.

NASA Begins Psyche Mission Review

NASA’s Science Mission Directorate and the Jet Propulsion Laboratory have commissioned an independent review to examine project and institutional issues that led to the Psyche mission missing its planned 2022 launch opportunity, and to review the mission’s path forward. The 15-member review board will be chaired by retired NASA official Tom Young and is slated to begin work on July 19. The review will study factors of workforce environment, culture, communication, schedule, and both technical and programmatic risks. Results of this study will help inform a continuation/ termination review for the mission, as well as provide NASA and JPL with actionable information to reduce risk for other missions. The board is expected to brief their findings to NASA and JPL leadership in late September.

NASA’s Psyche mission team continues to assess ongoing issues with the spacecraft’s flight software. The team is evaluating its ability to meet a schedule to launch in 2022 – the current launch period is Sept. 20 to Oct. 11. If it is determined that launch in 2022 is not possible, a full range of actions for how to proceed will be considered.

NASA’s Psyche Mission Launch Update

NASA’s Psyche spacecraft is nearing the final stages of preparations for launch, and the mission team is working to confirm that all hardware and software systems are operating correctly. An issue is preventing confirmation that the software controlling the spacecraft is functioning as planned. The team is working to identify and correct the issue. To allow more time for this work, the launch period is being updated to no earlier than Sept. 20, 2022, pending range availability.

The Psyche spacecraft completed its journey from NASA’s Jet Propulsion Laboratory (JPL) in Southern California to NASA’s Kennedy Space Center in Florida. First, it traveled to March Air Reserve Base, about 55 miles southeast of JPL, before flying cross-country aboard a C-17 aircraft to the Launch and Landing Facility (formerly the Shuttle Landing Facility) where crews offloaded the spacecraft. Over the next three months, the spacecraft will undergo additional preparations before launching aboard a SpaceX Falcon Heavy rocket on Aug. 1.

The Psyche spacecraft will use solar-electric propulsion to travel approximately 1.5 billion miles (2.4 billion kilometers) to rendezvous with its namesake asteroid in 2026. This will make it the first spacecraft to use Hall-effect thrusters beyond the orbit of the Moon. This thruster technology traps electrons in a magnetic field and uses them to ionize onboard propellant, expending much less propellant than equivalent chemical rockets. Psyche also carries three scientific instruments: an imager, magnetometer, and a gamma ray and neutron spectrometer.

The unique, metal-rich Psyche asteroid may be part of the core of a planetesimal, a building block of rocky planets in our solar system. Learning more about the asteroid could tell us more about how our own planet formed and help answer fundamental questions about Earth’s own metal core and the formation of our solar system.

The launch of Psyche will include two secondary payloads, NASA’s Deep Space Optical Communications (DSOC) technical demonstration, which is attached to the spacecraft as a separate experiment and the Janus spacecraft. DSOC will perform the agency’s first demonstration of optical communications beyond the Earth-Moon system, and will use lasers to send data at a higher rate than typical spacecraft radio communications. Janus is two small spacecraft that will study two different binary asteroids (two asteroids that orbit each other) to understand the formation and evolution of these objects.

The Psyche mission is led by Arizona State University. JPL, which is managed for NASA by Caltech in Pasadena, California, is responsible for mission’s overall management, system engineering, integration and testing, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis. NASA’s Launch Services Program (LSP), based at Kennedy, is managing the launch. Psyche will be the 14th mission in the agency’s Discovery program and LSP’s 100th primary mission. Numerous international, university, and commercial partners are part of the Psyche team.
