Technicians align, install, and then extend the second set of solar arrays, measuring 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high, for NASA’s Europa Clipper spacecraft inside the agency’s Payload Hazardous Servicing Facility at Kennedy Space Center in Florida on Thursday, Aug. 15, 2024. The huge arrays – spanning more than 100 feet when fully deployed, or about the length of a basketball court – will collect sunlight to power the spacecraft as it flies multiple times around Jupiter’s icy moon, Europa, conducting science investigations to determine its potential to support life.

In the Payload Hazardous Servicing Facility, technicians lower a crane over the Phoenix Mars Lander spacecraft. The crane will be used to remove the heat shield from around the Phoenix. The Phoenix mission is the first project in NASA's first openly competed program of Mars Scout missions. Phoenix will land in icy soils near the north polar permanent ice cap of Mars and explore the history of the water in these soils and any associated rocks, while monitoring polar climate. Landing is planned in May 2008 on arctic ground where a mission currently in orbit, Mars Odyssey, has detected high concentrations of ice just beneath the top layer of soil. It will serve as NASA's first exploration of a potential modern habitat on Mars and open the door to a renewed search for carbon-bearing compounds, last attempted with NASA’s Viking missions in the 1970s. A stereo color camera and a weather station will study the surrounding environment while the other instruments check excavated soil samples for water, organic chemicals and conditions that could indicate whether the site was ever hospitable to life. Microscopes can reveal features as small as one one-thousandth the width of a human hair. Launch of Phoenix aboard a Delta II rocket is targeted for Aug. 3 from Cape Canaveral Air Force Station in Florida.

In the Payload Hazardous Servicing Facility, the heat shield for the Phoenix Mars Lander is moved into position for installation on the spacecraft. The Phoenix mission is the first project in NASA's first openly competed program of Mars Scout missions. Phoenix will land in icy soils near the north polar permanent ice cap of Mars and explore the history of the water in these soils and any associated rocks, while monitoring polar climate. Landing is planned in May 2008 on arctic ground where a mission currently in orbit, Mars Odyssey, has detected high concentrations of ice just beneath the top layer of soil. It will serve as NASA's first exploration of a potential modern habitat on Mars and open the door to a renewed search for carbon-bearing compounds, last attempted with NASA's Viking missions in the 1970s. A stereo color camera and a weather station will study the surrounding environment while the other instruments check excavated soil samples for water, organic chemicals and conditions that could indicate whether the site was ever hospitable to life. Microscopes can reveal features as small as one one-thousandth the width of a human hair. Launch of Phoenix aboard a Delta II rocket is targeted for Aug. 3 from Cape Canaveral Air Force Station in Florida.

Launch of Phoenix aboard a Delta II rocket is targeted for Aug. 3 from Cape Canaveral Air Force Station in Florida.

Technicians test and extend one of the two “wings” comprising the solar arrays for NASA’s Europa Clipper spacecraft on Friday, Aug. 23, 2024, at the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida. Each array measures about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high. The spacecraft needs the massive solar arrays to power to Jupiter’s icy moon Europa to help scientists better understand the astrobiological potential for habitable worlds beyond our planet.

Technicians install and align the second set of solar arrays for NASA’s Europa Clipper spacecraft inside the agency’s Payload Hazardous Servicing Facility at Kennedy Space Center in Florida on Thursday, Aug. 15, 2024. The Europa Clipper spacecraft will need the 46.5 feet (14.2 meter) long, five-panel solar arrays on each side, to gather enough sunlight to power the spacecraft to perform flybys around Jupiter’s icy moon, Europa, so science instruments aboard the spacecraft can determine if the moon could hold the building blocks necessary to sustain life.

The payload fairing for NASA's Transiting Exoplanet Survey Satellite (TESS) is moved inside the Payload Hazardous Servicing Facility at the agency's Kennedy Space Center in Florida. Inside the facility, TESS will be encapsulated in the payload fairing. The satellite is scheduled to launch atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station on April 16. The satellite is the next step in NASA's search for planets outside our solar system, known as exoplanets. TESS is a NASA Astrophysics Explorer mission led and operated by MIT in Cambridge, Massachusetts, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dr. George Ricker of MIT’s Kavli Institute for Astrophysics and Space Research serves as principal investigator for the mission. Additional partners include Orbital ATK, NASA’s Ames Research Center, the Harvard-Smithsonian Center for Astrophysics and the Space Telescope Science Institute. More than a dozen universities, research institutes and observatories worldwide are participants in the mission. NASA’s Launch Services Program is responsible for launch management.

Each array measures about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high when extended. The spacecraft needs the massive solar arrays to power to Jupiter’s icy moon Europa to help scientists better understand the astrobiological potential for habitable worlds beyond our planet.

In the Payload Hazardous Servicing Facility, the Phoenix Mars Lander spacecraft undergoes spin testing. The Phoenix mission is the first project in NASA's first openly competed program of Mars Scout missions. Phoenix will land in icy soils near the north polar permanent ice cap of Mars and explore the history of the water in these soils and any associated rocks, while monitoring polar climate. Landing is planned in May 2008 on arctic ground where a mission currently in orbit, Mars Odyssey, has detected high concentrations of ice just beneath the top layer of soil. It will serve as NASA's first exploration of a potential modern habitat on Mars and open the door to a renewed search for carbon-bearing compounds, last attempted with NASA's Viking missions in the 1970s. A stereo color camera and a weather station will study the surrounding environment while the other instruments check excavated soil samples for water, organic chemicals and conditions that could indicate whether the site was ever hospitable to life. Microscopes can reveal features as small as one one-thousandth the width of a human hair.

Technicians prepare to encapsulate NASA’s Europa Clipper spacecraft inside SpaceX’s Falcon Heavy payload fairing in the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida on Wednesday, Oct. 2, 2024. The payload fairing will protect the spacecraft during liftoff from Launch Complex 39A on its journey to explore Jupiter’s icy moon, Europa. The spacecraft will complete nearly 50 flybys of Jupiter’s icy moon, Europa, to determine if there are conditions suitable for life beyond Earth.
