This thesis presents the modeling, analysis and software simulation of one of the docking mechanisms called "probe and drogue". The aim of this thesis is to model the docking mechanism, simulate the docking process and use the results as a reference for the Hardware-In-the-Loop simulation (HIL) of the docking mechanism, in order to verify and validate it.

  • ISS Interface Mechanisms and Their Lineage
    ISS Interface Mechanisms and their Heritage The International Space Station, by nurturing technological development of a variety of pressurized and unpressurized interface mechanisms fosters “competition at the technology level”. Such redundancy and diversity allows for the development and testing of mechanisms that might be used for future exploration efforts. The International Space Station, as a test-bed for exploration, has 4 types of pressurized interfaces between elements and 6 unpressurized attachment mechanisms. Lessons learned from the design, test and operations of these mechanisms will help inform the design for a new international standard pressurized docking mechanism for the NASA Docking System. This paper will examine the attachment mechanisms on the ISS and their attributes. It will also look ahead at the new NASA docking system and trace its lineage to heritage mechanisms.

  • GLEX Outline
    GLEX Outline Human exploration missions beyond low earth orbit will likely require international cooperation in order to leverage limited resources. International standards can help enable cooperative missions by providing well understood, predefined interfaces allowing compatibility between unique spacecraft and systems. The International Space Station (ISS) partnership has developed a publically available International Docking System Standard (IDSS) that provides a solution to one of these key interfaces by defining a common docking interface. The docking interface provides a way for even dissimilar spacecraft to dock for exchange of crew and cargo, as well as enabling the assembly of large space systems. This paper provides an overview of the key attributes of the IDSS, an overview of the NASA Docking System (NDS), and the plans for updating the ISS with IDSS compatible interfaces. The NDS provides a state of the art, low impact docking system that will initially be made available to commercial crew and cargo providers. The ISS will be used to demonstrate the operational utility of the IDSS interface as a foundational technology for cooperative exploration. Introduction Since the beginning of human spaceflight, the need to join elements together in space has been a key capability. The need for this capability is driven largely by economics and physics – it is virtually impossible to build and launch a unitary spacecraft that can perform all expected missions on a single flight from the Earth’s surface. This capability can support a broad range of needs, such as enabling (inherently small) transportation systems to and from planetary bodies, assembling habitats in space by allowing launch of two or more modules on reasonable sized launch vehicles for space stations/ long transit habitats, and specialized spacecraft for short term missions to arrive and depart from such habitats.

RESULTS IN BRIEF NASA’s Management of the Gateway Program for Artemis Missions NASA Office of Inspector General Office of Audits November 10, 2020 IG-21-004 (A-20-008-00) WHY WE PERFORMED THIS AUDIT In March 2019, the Administration directed NASA to execute a plan to land humans on the Moon’s South Pole by 2024, 4 years sooner than NASA’s intended schedule. In response, the NASA Administrator announced that the return-to-the- Moon mission would be known as Artemis and the Agency would use innovative acquisition practices to help accelerate the timetable. The Artemis program includes two exploration missions to orbit the Moon in 2021 and 2023 using the Space Launch System rocket and Orion Multi-Purpose Crew Vehicle (Orion), both of which remain under development and have yet to be flown together.
