CFI’02 compared a sector-oriented approach to arrival flow management to a candidate trajectory-oriented approach. The sector-oriented approach was based on the existing 2002 operations for handling arrival traffic in a time-based metering situation. The trajectory-oriented approach provided advanced tools for the controller and introduced a more active interaction with the traffic management coordinator (TMC).

Human Systems Integration Division Crew Activity Tracking System (CATS) The Crew Activity Tracking System (CATS) was developed to track human operator activities in order to detect deviations from correct operations that may impact the safety of complex systems. It supports visualization and analysis of operator-caused deviations and the context surrounding them. CATS has a computational hierarchical model of the preferred way to control the system.

The Distributed Air/Ground Traffic Management (DAG-TM) concept is a coherent set of conceptual elements that describes possible modes of operation within the outlines of the Free Flight concept defined by the RTCA Task Force. It was originally conceived as one possible approach to the potential implementation of Free Flight, progressing along the path started by the Free Flight Phase 1 activities. This DAG-TM concept was developed by the Advanced Air Transportation Technologies (AATT) Project.

A NASA Launch Services (NLS) II contract has been awarded by the agency to Relativity Space Inc., and its Terran R launch service in accordance with the contract’s on-ramp provision. The Terran R launch service will be available to NASA’s launch services to use for future missions. The NLS II contracts are multiple-award, indefinite-delivery/indefinite-quantity contracts with an ordering period through June 2030 and an overall period of performance through December 2032.

Office of Small Business Programs JPL (Caltech) Small Business Subcontracting Program The Small Business Programs Office serves as the conduit between JPL and subcontractors and/or companies seeking procurement opportunities. JPL is fully committed to the maximum utilization of small businesses, and this office helps small businesses think BIG.

Expedition 75 flight engineers Anil Menon and Sophie Adenot and International Space Station commander Jessica Meir gather together and celebrate Meir’s 400 cumulative days in space with a commemorative patch on Aug. 28. Vein scans, ultra-hot physics, and Earth observations were the main research activities aboard the International Space Station on Wednesday. The Expedition 75 crew members rounded out their mid-week shift and swapped out spacesuit components and serviced life support gear.

Recognizing those who were instrumental in NACA and NASA Langley’s successes.

Henry Helgeson serves as the associate administrator for the Office of Communications at NASA Headquarters in Washington. In this capacity, he leads global communications strategy, public engagement, branding, media relations, and digital enterprise projects across all NASA centers.

Hurricane Melissa is seen 50 miles south of Jamaica in this photograph taken from the International Space Station on Oct. 28, 2025. Last November, NASA and its European partners launched the Sentinel-6B satellite to improve hurricane forecasts, help protect infrastructure, and benefit commercial industries, including shipping. The satellite now is flying 30 seconds behind its predecessor, Sentinel-6 Michael Freilich.

The crew of NASA’s Artemis II mission – NASA astronauts Christina Koch, Victor Glover, and Reid Wiseman and CSA (Canadian Space Agency) astronaut Jeremy Hansen – visited Huntsville, Alabama, Sept. 1, 2026, where they met with the NASA workforce at NASA’s Marshall Space Flight Center.
