On the early morning of November 10, an Atlas V rocket launched JPSS-2, NOAAs newest ecological satellite into orbit. Riding on the rocket was NASAs Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID). This mission demonstrated a cross-cutting aeroshell– a kind of heat guard– for climatic re-entry.
For locations with an atmosphere, among the obstacles NASA faces is how to provide heavy payloads (experiments, devices, and individuals) since present stiff aeroshells are constrained by a rockets shroud size. One response is an inflatable aeroshell that can be released to a scale much bigger than the shroud. This technology enables a variety of proposed NASA objectives to destinations such as Mars, Venus, and Titan as well as return to Earth.
When a spacecraft gets in an atmosphere, aerodynamic forces act upon it. Particularly, aerodynamic drag helps to slow it down, converting its kinetic energy into heat. Using climatic drag is the most mass-efficient approach to decrease a spacecraft.

LOFTIDs big deployable aeroshell– an inflatable structure secured by a versatile heat shield– acts as a giant brake as it passes through the Martian atmosphere. The big aeroshell develops more drag than a standard, smaller rigid aeroshell.
LOFTID is demonstrating a big aeroshell– 6 meters in size or about 20 feet– entry from low-Earth orbit, to show this technology in conditions pertinent to many prospective applications. The benefits of utilizing the inflatable decelerator design for a range of area applications include:
Low-Earth orbit return; complimentary leaflet, in-space manufactured materials [3 to 6-meter scale] International Space Station down mass greater than currently possible [8 to 12-meter scale] Lower expense access to area through launch vehicle asset recovery [12-meter scale]
The inflatable decelerator innovation is scalable to both crewed and big robotic missions to Mars.
On November 10, the launch, deployment, and recovery of LOFTID and its data capsule were successful. Now scientists need to assess the information recorded throughout the test to find out about the outcomes.

NASAs Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) is committed to the memory of Bernard Kutter– a manager of advanced programs at United Launch Alliance (ULA) who promoted lower-cost access to space and innovations to make that a reality. LOFTID is a collaboration in between NASAs Space Technology Mission Directorate and ULA to show an inflatable aerodynamic decelerator, or aeroshell, technology that could one day aid land human beings on Mars.
Considering that NASAs beginning in 1958, the firm has actually relied greatly on rigid aeroshells (a protective shell composed of a heat shield and a back shell), parachutes, and retro-propulsion (rockets) to decelerate individuals, vehicles, and hardware throughout orbital entry, descent, and landing operations. The LOFTID presentation is poised to change the way NASA and industry provide payloads to planetary locations with atmospheres.
After more than a decade of advancement of Hypersonic Inflatable Aerodynamic Decelerator (HIAD) innovation, consisting of 2 suborbital flight tests, the LOFTID orbital flight test is the next action. This return from orbit demonstration provides an entry environment appropriate to lots of potential applications, leading the way for its use on future objectives. The LOFTID re-entry car, at 19.7 feet (6 meters) size, will be the biggest blunt body aeroshell to ever go through climatic entry.
When a spacecraft goes into an environment, aerodynamic forces– like drag– act on it, slowing it down and converting its kinetic energy into heat. Utilizing climatic drag normally is the most mass-efficient technique to decrease a spacecraft. Considering that HIAD innovation is larger than traditional aeroshells, it develops more drag and begins the deceleration process in the upper reaches of the atmosphere, enabling not only much heavier payloads, but also landing at greater altitudes. It might additionally be used to bring an unprecedented quantity of mass back from low-Earth orbit, consisting of items from the International Space Station. Another substantial possible advantage is enabling the healing of rocket possessions for reuse which can decrease the overall expense of access to space.
The HIAD design consists of an inflatable structure that keeps its shape against the drag forces, and a protective flexible thermal defense system that holds up against the heat of reentry. The inflatable structure is built with a stack of pressurized concentric rings, or tori, that are strapped together to form an extremely strong blunt cone-shaped structure.
The rings are made from braided artificial fibers that are, by weight, 10 times more powerful than steel. A flexible thermal protection system insulates the rings from the searing heat of atmospheric entry; LOFTID can hold up against temperatures in excess of 2900 ° F (1600 ° C). Its constructed with 3 layers: an exterior ceramic fiber cloth layer to keep integrity of the surface area, a middle layer of insulators to prevent heat transmission, and an interior layer that avoids hot gas from reaching the inflatable structure. The flexible thermal protection system is also foldable, packable, deployable, and tailorable. Because it is versatile, it uses up less space in the rocket and permits the design to be scalable.
LOFTID is managed by the companys Langley Research Center in Hampton, Virginia, with contributions from various NASA centers: Ames Research Center in Silicon Valley, California; Marshall Space Flight Center in Huntsville, Alabama; and Armstrong Flight Research Center in Edwards, California. NASAs Launch Services Program, based at the firms Kennedy Space Center in Florida, handled todays launch.
Hitching a ride on the rocket was NASAs Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID). NASAs Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, is showing a cross-cutting aeroshell– a type of heat guard– for climatic re-entry. LOFTIDs large deployable aeroshell– an inflatable structure safeguarded by a flexible heat shield– acts as a huge brake as it passes through the Martian environment. The information module resembles a big lemon and holds a backup copy of the information taped throughout LOFTIDs presentation. After more than a years of development of Hypersonic Inflatable Aerodynamic Decelerator (HIAD) innovation, consisting of two suborbital flight tests, the LOFTID orbital flight test is the next step.
