Hopper dredge Essayons operates in the Columbia River near Cathlamet, Washington on July 25, 2022.

CAPE CANAVERAL, Fla. - At Launch Pad 39A at NASAs Kennedy Space Center in Florida, technicians work to move the Hubble payload canister into the payload changeout room for space shuttle Atlantis STS-125 mission. The canister arrived at the pad on Saturday evening; however, early Sunday morning technicians were unable to place the canister into the pads payload changeout room. Teflon pads on “shoes” attached to the outside of the payload canister that help the canister move along the guide rails didnt fit properly. The shoes were removed and several options were considered, including slightly shaving down the pads so the shoes will fit onto the rails. STS-125 is the fifth and final shuttle Hubble Space Telescope servicing mission. Atlantis launch is targeted for Oct. 10.

A member in support of Joint Task Force-Red Hill (JTF-RH) begins the process of removing residual fuel from the Red Hill Bulk Fuel Storage Facility Jan. 15, 2024, Halawa, Hawaii. This follows the successful gravity defueling operation completed on December 16, 2023, where over 104 million gallons of fuel were safely removed. Approximately 64,000 gallons of remaining fuel in the facility pipelines will now be addressed by JTF-RH, with an estimated 60,000 gallons set to be removed through a careful process, expected to conclude by the end of March. The newly formed Navy Closure Task Force-Red Hill (NCTF-RH) is now integrating with JTF-RH and will assume responsibility for the facility's closure, including the removal of the final 4,000 gallons of fuel. JTF-RH and NCTF-RH are committed to working with regulators and government stakeholders to ensure Red Hill is defueled safely, expeditiously, and in compliance with all applicable laws and regulations.
