  • packing programming of space station Spacewalk events based on bin packing theory and differential evolution algorithm
    Congress on Evolutionary Computation, 2016
    Co-Authors: Yuehe Zhu, Ya-zhong Luo, Jin Zhang
    Abstract:

    During orbital operations of the space station, several test missions require astronauts to conduct extravehicular activities. Because of the limitations of man-hours and resources such as extravehicular spacesuits, the overall programming of Spacewalk events is a critical issue to address in operation mission planning for the space station. Based on the theory of bin packing, this paper establishes a new type of programming optimization model for Spacewalk events and proposes optimization strategies based on the differential evolution (DE) algorithm. The optimization results from a planning test case that consists of 41 Spacewalk events reveal a modified DE algorithm capable of obtaining the optimal programming scenario.

  • STS-97 Crew Training
    2017
    Co-Authors: Nasa
    Abstract:

    The crew of STS-97, Commander Brent W. Jett, Pilot Michael J. Bloomfield, and Mission Specialists Joseph R. Tanner, Carlos I. Noriega, and Marc Garneau are shown during various stages of their training. Footage shows them during a food tasting, during emergency bailout training, Spacewalk training, and de-orbit preparation.

  • STS-109 Flight Day 7 Highlights
    2017
    Co-Authors: Nasa
    Abstract:

    The Hubble Space Telescope (HST) is seen on its berthing platform on the rear of the cargo bay of the Columbia Orbiter. Additional footage shows the port solar array of the HST as well as the area where the new thermal blanket was installed. Mission Specialists James Newman and Michael J. Massimino are performing their Spacewalk. The footage includes Newman unbolting and sliding out the Faint Object Camera, moving it into storage, then lifting the Advanced Camera for Surveys (ACS) out of the cargo bay, and Massimino installing the ACS. The second stage of their Spacewalk shows Newman retrieving the Electronic Support Module out of the cargo bay, and assisting Massimino as he installs the module and its connectors in front of the ACS. As they return to Columbia, additional members of the crew are seen preparing spacesuits for the following day's Spacewalk and cleaning the seals on the airlock. The video concludes with Pilot Duane G. Carey interviewing Massimino about his Spacewalk using internet questions from school children.

  • STS-88 Crew Interview: Nancy Currie
    2017
    Co-Authors: Nasa
    Abstract:

    Nancy Currie discusses the seven-day mission that will be highlighted by the mating of the U.S.-built Node 1 station element to the Functional Energy Block (FGB) which will already be in orbit, and two Spacewalks to connect power and data transmission cables between the Node and the FGB. Node 1 will be the first Space Station hardware delivered by the Space Shuttle. He also disscusses the assembly sequence. The crew will conduct a series of rendezvous maneuvers similar to those conducted on other Shuttle missions to reach the orbiting FGB. Once the two elements are docked, Ross and Newman will conduct two scheduled Spacewalks to connect power and data cables between the Node, PMAs and the FGB. The day following the Spacewalks, Endeavour will undock from the two components, completing the first Space Station assembly mission.
