Here is a closeup of some of the X-59’s wiring and instrumentation system. Displayed here is the remote instrumentation encoder, which can be found in the wing of the aircraft. This encoder communicates with the plane’s other instrumentation systems like pressure and temperature sensors within the X-59.

Some of the team members who make up the Artemis closeout team pose for a picture at Launch Complex 39B at NASA’s Kennedy Space Center in Florida on Tuesday, Aug. 13, 2024. Members of the closeout crew, pad rescue team, and the Exploration Ground Systems Program practiced the process of getting inside and out of the emergency egress baskets. While the crew and other personnel will ride the emergency egress baskets to the terminus area in a real emergency, no one rode the baskets for this test. Instead, teams tested the baskets during separate occasions by using water tanks filled to different levels to replicate simulate the weight of passengers.

CAPE CANAVERAL, Fla. - Inside Orbiter Processing Facility-1 at Kennedy Space Center in Florida, technicians close shuttle Atlantis’ hatch in preparation for the Mylar Pull Test. During the test, the hatch is closed and a scale is used to measure the force required to pull a piece of Mylar paper out from between the door and structural wall thermal barriers. The pull test is performed to ensure the integrity of the hatch and that it has closed properly. Atlantis is being processed for the STS-132 mission targeted for launch May 14.

KENNEDY SPACE CENTER, FLA. - In the Orbiter Processing Facility, a worker checks out part of the equipment in the airlock, at one end of Discovery’s payload bay. The airlock is sized to accommodate two fully suited flight crew members simultaneously. Support functions include airlock depressurization and repressurization, extravehicular activity equipment recharge, liquid-cooled garment water cooling, EVA equipment checkout, donning and communications. The outer hatch isolates the airlock from the unpressurized payload bay when closed and permits the EVA crew members to exit from the airlock to the payload bay when open.

KENNEDY SPACE CENTER, FLA. -- A thermal technician with Johns Hopkins University Applied Physics Laboratory closes out the blanket around CONTOUR'S Earth-Sun Sensor. The spacecraft will provide the first detailed look into the heart of a comet -- the nucleus. Flying as close as 60 miles (100 kilometers) to at least two comets, the spacecraft will take the sharpest pictures yet of a nucleus while analyzing the gas and dust that surround these rocky, icy building blocks of the solar system. Launch of CONTOUR aboard a Boeing Delta II rocket is scheduled for July 1 from Launch Pad 17-A, Cape Canaveral Air Force Station

This close-up shows the 12-inch-long dent on Shuttle Discovery's main propulsion system liquid hydrogen recirculation line that was discovered during routine aft compartment inspections Tuesday, Dec. 7. The line recirculates hydrogen from the Shuttle main engines back to the external tank during prelaunch engine conditioning. The line is being replaced and managers expect the replacement work to take about 3 days, followed by system retests and final aft compartment close-outs. Preliminary assessments reflect a launch date of Space Shuttle Discovery on mission STS-103 no earlier than Dec. 16. STS-103 is the third servicing mission for the Hubble Space Telescope

During the spacewalk, Canadian Space Agency's astronaut Dave Williams (out of frame) and astronaut Rick Mastracchio (out of frame), both STS-118 mission specialists, removed a faulty control moment gyroscope (CMG-3) and installed a new CMG into the station's Z1 truss. The failed CMG will remain at its temporary stowage location on the station's exterior before it is returned to Earth on a later shuttle mission. The new gyroscope is one of four CMGs that are used to control the station's attitude in orbit.

After assembling and powering up the empty suit as if it were about to go out on another spacewalk, Parmitano and NASA astronaut Chris Cassidy (both out of frame), both Expedition 36 flight engineers, observed water once again leaking into the helmet. With the issue reproduced, NASA now has a baseline configuration for the crew to begin swapping out parts for additional tests to pinpoint the problem. There are also opportunities to either launch replacement parts on upcoming cargo flights or return parts to Earth for further study once more is known about the cause of the issue.

S130-E-011235 (20 Feb. 2010) --- After several days of seeing out-the-window close-up views of the various elements of the International Space Station, the STS-130 crewmembers aboard the space shuttle Endeavour got a fresh look at the home planet after separating from the orbital outpost. Eleven astronauts and cosmonauts worked together to continue construction on the orbital outpost and perform other tasks in tandem.

Williams, Expedition 13 NASA space station science officer and flight engineer, is photographed during a 5-hour, 54-minute excursion which he shared with European Space Agency astronaut Thomas Reiter (out of frame). For part of the spacewalk, the pair worked closely in tandem, and then worked separately, getting ahead of their timeline, thus enabling the two to tack on extra tasks.

This annotated, high-resolution image of Jupiter's main dust ring was collected by the Stellar Reference Unit (SRU) navigation camera aboard NASA's Juno spacecraft. The image was taken from inside the ring looking out as Juno flew between Jupiter and the radiation belts during the spacecraft's 36th close flyby on Sept. 2, 2021. The brightest thin dust bands are associated with the orbits of Jupiter's small moons, Metis and Adrastea. The image also captured an arm of the Perseus constellation, as shown in the annotation. https://photojournal.jpl.nasa.gov/catalog/PIA25039

KENNEDY SPACE CENTER, FLA. -- In the transfer aisle of the Vehicle Assembly Building, workers take a close look at the orbiter Atlantis before it is lifted up into high bay 1. After the lift, it will be lowered onto the mobile launcher platform where the external tank and solid rocket boosters are already stacked. Space Shuttle Atlantis is targeted to roll out to Launch Pad 39A on February 14 for mission STS-117. The mission is No. 21 to the International Space Station and construction flight 13A.

KENNEDY SPACE CENTER, FLA. -- Rodney Wilson, with United Space Alliance, inspects the range safety cable between the external tank and solid rocket boosters (SRB) on Space Shuttle Discovery. The cable, which relays a redundant emergency destruction signal between the SRBs in the unlikely event of a contingency, was damaged during close-out operations and is being replaced. Discovery's processing schedule leads to a target launch date of Dec. 6

This is one artist's concept of Kuiper Belt object 2014 MU69, the next flyby target for NASA's New Horizons mission. This binary concept is based on telescope observations made at Patagonia, Argentina, on July 17, 2017, when MU69 passed in front of a star. New Horizons scientists theorize that it could be a single body with a large chunk taken out of it, or two bodies that are close together or even touching. https://photojournal.jpl.nasa.gov/catalog/PIA21867
