A deployable decelerator like a parachute can slow down a spacecraft after a heat shield. [5] Typically a Disk-Gap-Band parachute has been used, but another possibility are trailing or attached inflatable entry devices. [5]
NASA is testing a deployable heat shield solution in space as a secondary payload on the launch that will deliver the NASA JPSS-2 launch in late 2022. The Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) is designed to demonstrate aerobraking and re-entry from 18,000 miles per hour after separation from the launch vehicle ...
Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) was a NASA mission to test inflatable reentry systems. [1] It was the first such test of an inflatable decelerator from Earth-orbital speed. LOFTID was launched on an Atlas V 401 in November 2022 as a secondary payload, along with the JPSS-2 weather satellite. [2]
The fundamental design objective in atmospheric entry of a spacecraft is to dissipate the energy of a spacecraft that is traveling at hypersonic speed as it enters an atmosphere such that equipment, cargo, and any passengers are slowed and land near a specific destination on the surface at zero velocity while keeping stresses on the spacecraft ...
The Low-Density Supersonic Decelerator or LDSD is a reentry vehicle designed to test techniques for atmospheric entry on Mars.The disc-shaped LDSD uses an inflatable structure called the Supersonic Inflatable Aerodynamic Decelerator (SIAD), which is essentially a donut-shaped balloon, to create atmospheric drag in order to decelerate the vehicle before deploying a large supersonic parachute. [2]
Aerocapture is an orbital transfer maneuver in which a spacecraft uses aerodynamic drag force from a single pass through a planetary atmosphere to decelerate and achieve orbit insertion. Aerocapture uses a planet's or moon's atmosphere to accomplish a quick, near-propellantless orbit insertion maneuver to place a spacecraft in its science orbit .
WASHINGTON (Reuters) -NASA affirmed on Wednesday a plan it set last year to work with Elon Musk's SpaceX in returning two astronauts from the International Space Station, saying it will do so "as ...
The Low-Density Supersonic Decelerator or LDSD is a space vehicle designed to create atmospheric drag in order to decelerate during entry through a planet's atmosphere. [13] It is essentially a disc-shaped vehicle containing an inflatable, doughnut-shaped balloon around the outside.
