Enhanced meteoroid and orbital debris shielding
TL;DR: The Stuffed Whipple (SW) shield as mentioned in this paper was developed by NASA Johnson Space Center (JSC) and Marshall Space Flight Center (MSFC) engineers to enhance the protection of conventional Whipple shields.
Meteoroid/Debris Shielding
TL;DR: In this paper, the authors provide innovative, low-weight shielding solutions for spacecraft and the ballistic limit equations that define the shield's performance in the meteoroid/debris environment.

TL;DR: Gated x-ray imaging is used to detect the x-rays emission from the imploded core of symmetry capsules at the National Ignition Facility, and how that set was used to predictably tune the implosion symmetry as the laser energy, the laser cone wavelength separation, and the Hohlraum size were increased to ignition scales is described.

Ballistic limit equations for spacecraft shielding
TL;DR: In this article, the authors provided equations describing the ballistic performance capability of meteoroid/orbital debris (M/OD) shield systems employed on the International Space Station (ISS).
Journal ArticleDOI
Impact Features and Projectile Residues in Aerogel Exposed on Mir
TL;DR: In this article, a SiO2-based aerogel (0.63 m2) was exposed for 18 months on the Mir Station to capture hypervelocity particles from both man-made and natural sources.

Hypervelocity impact in metals, glass and composites
TL;DR: A review of hypervelocity impact research carried out during the intense activity period leading up to the Apollo lunar missions is provided in this paper, where the specific areas covered include cratering and spallation in thick, semi-infinite targets, perforation and hole formation in thin, single-thickness targets, spaced dual sheet armor, impact radiation, and impact ionization.
Journal ArticleDOI
A multi-shock concept for spacecraft shielding
TL;DR: In this article, a spacecraft-shielding technique is investigated in which the geometrical configuration and material used are emphasized, and ultrathin spaced shield elements are employed to repeatedly shock the impacting projectile to a high energy state that causes melting and vaporization.
Journal ArticleDOI
Mesh double-bumper shield: A low-weight alternative for spacecraft meteoroid and orbital debris protection
TL;DR: The mesh double-bumper (MDB) shield as discussed by the authors was developed to demonstrate that a Whipple shield could be augmented or modified to substantially improve protection by adding a mesh a short distance in front of the Whipple bumper and inserting a layer of high strength fabric between the second bumper and rear wall.
Proceedings ArticleDOI
Advanced meteoroid and debris shielding concepts
TL;DR: The results of the shielding screening and optimization work conducted at the NASA Johnson Space Center Hypervelocity Impact Research Laboratory (HIRL) are described in this article, where the impact tests to investigate and optimize certain aspects of the aluminum mesh double-bumper concept, which was considered the best performer in the screening test, are analyzed.
Proceedings ArticleDOI
Meteoroid protection by multiwall structures.
TL;DR: Multiwall meteoroid protection design in Apollo program, discussing bumper, backup sheet and honeycomb cells insulation is discussed in this article, where the authors also discuss the impact of meteoroids on the Apollo program.
