In a clean room at NASA's Jet Propulsion Laboratory in Southern California in March 2024, engineers and technicians pose with the agency's Farside Seismic Suite while the payload is readied for testing. The suite contains two instruments that will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. The two seismometers are packaged together with a large battery, a computer, and electronics inside a cube structure that's surrounded by several layers of insulation (the shiny material at center) and suspended within a protective outer cube, which is, in turn, covered with an insulating blanket. In this photo, the blanket has not yet been attached. Members of the FSS integration team pictured are (from left) Salvador Ramirez, Asad Aboobaker, Nik Schwarz, Joanna Farias, Clara MacFarland, Frank Barone, Hsin-Yi Hao, Nicholas Roy-Steier, and Vik Singh. https://photojournal.jpl.nasa.gov/catalog/PIA26342

FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. Here, engineers move FSS onto a fixture that will allow them to tilt the payload, simulating the pull of lunar gravity in the direction at which one of the instrument's two seismometers is sensitive to motion. (The Moon's gravity is about one-sixth of Earth's.) Called an ambient tilt test, this activity allows engineers to check the seismometers' performance. The two seismometers are packaged together with a large battery, a computer, and electronics inside a cube structure that's surrounded by several layers of insulation and suspended within an outer protective cube, which is in turn covered with a shiny insulating blanket. The suite's single solar panel can be seen right of center.

In a clean room at NASA's Jet Propulsion Laboratory in Southern California in March 2024, engineers and technicians work to prepare the agency's Farside Seismic Suite (FSS) for environmental testing to simulate conditions it will encounter in space. Along with being placed in a vacuum chamber and subjected to extreme temperatures, the instrument suite will undergo severe shaking that mimics the rocket's motion during launch. The cube-shaped payload contains two instruments that will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights.

NASA's Farside Seismic Suite (FSS) is assembled in a clean room at the agency's Jet Propulsion Laboratory in Southern California in November 2023. Two sensitive seismometers packaged in the suite's cube-within-a-cube structure will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. Seen here is the inner cube structure, with the suite's large battery at rear. The gold, puck-shaped device at left is the Short Period sensor, or SP, which measures motion in three directions using sensors etched into a trio of square silicon chips, each about 1 inch (25 millimeters) wide. At right, within the silver cylindrical enclosure, is the Very Broadband seismometer, or VBB, the most sensitive seismometer ever built for use in space exploration. It can detect ground motions smaller than the size of a single hydrogen atom, measuring up-and-down movement using a pendulum held in place by a spring. Constructed as a backup instrument (a "flight spare") for NASA's InSight Mars lander by the French space agency, CNES (Centre National d'Études Spatiales), the VBB was slightly modified and packaged in a new enclosure for lunar use. The suite's computer and electronics are packed alongside the battery and seismometers. After being encased in insulation, this inner cube was suspended within a protective outer cube, which was in turn covered with a shiny insulating blanket. https://photojournal.jpl.nasa.gov/catalog/PIA26300

The astronauts are at Kennedy to prepare for launch as part of the Terminal Countdown Demonstration Test activities. The TCDT includes equipment familiarization and a simulated launch countdown. The crew of space shuttle Discovery is targeted to launch on the STS-119 mission Feb. 12. During Discovery's 14-day mission, the crew will install the S6 truss segment and solar arrays to the starboard side of the International Space Station, completing the station's truss, or backbone.

KENNEDY SPACE CENTER, FLA. -- In the White Room on Launch Pad 39A, STS-117 Mission Specialist John "Danny" Olivas is helped by the closeout crew to secure his launch suit before climbing into Space Shuttle Atlantis. Behind Olivas is Pilot Lee Archambault. The mission to the International Space Station is scheduled to launch at 7:38 p.m. EDT. Members of the closeout crew help the astronauts don a parachute pack, strap them into the space shuttle's crew module and take care of any other last-minute needs that arise. The White Room is at the end of the orbiter access arm that extends from the fixed service structure and provides entry into the orbiter. The shuttle is delivering a new segment to the starboard side of the space station's backbone, known as the truss. Three spacewalks are planned to install the S3/S4 truss segment, deploy a set of solar arrays and prepare them for operation. STS-117 is the 118th space shuttle flight, the 21st flight to the station, the 28th flight for Atlantis and the first of four flights planned for 2007. Photo credit: NASA/Tony Gray & Don Kight

KENNEDY SPACE CENTER, FLA. -- With the Rotating Service Structure rolled back, Space Shuttle Atlantis stands ready for launch on mission STS-110. The Orbiter Access Arm extends from the Fixed Service Structure (FSS) to the crew compartment hatch, through which the STS-110 crew will enter Atlantis. The RSS provides protected access to the orbiter for changeout and servicing of payloads at the pad. The structure has access platforms at five levels to provide access to the payload bay. The FSS provides access to the orbiter and the RSS. . Mission STS-110 is scheduled to launch April 4 on its 11-day mission to the International Space Station
