No one knows where the rocket... Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: uncontrolled entry, such as the entry of astronomical objects, space debris, or bolides; and … See more The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the … See more There are several basic shapes used in designing entry vehicles: Sphere or spherical section The simplest axisymmetric shape is the sphere or spherical section. This can either be a complete sphere or a spherical section forebody … See more A thermal protection system, or TPS, is the barrier that protects a spacecraft during the searing heat of atmospheric reentry. A secondary goal may be to protect the spacecraft from the See more Deceleration for atmospheric reentry, especially for higher-speed Mars-return missions, benefits from maximizing "the drag area of the entry system. The larger the diameter of the aeroshell, the bigger the payload can be." An inflatable aeroshell provides … See more When atmospheric entry is part of a spacecraft landing or recovery, particularly on a planetary body other than Earth, entry is part of a … See more Objects entering an atmosphere from space at high velocities relative to the atmosphere will cause very high levels of heating. Atmospheric entry heating comes principally from two … See more In 2004, aircraft designer Burt Rutan demonstrated the feasibility of a shape-changing airfoil for reentry with the sub-orbital See more

WebThis is a list of artificial objects reentering Earth's atmosphere by mass (see space debris ). Such objects are often completely destroyed by reentry heating, but large enough objects or components can survive. WebApr 16, 2001 · Earth, primarily because drag on the object is directly proportional to atmospheric density, and atmospheric density varies greatly at high altitudes. In general, we can predict the time that reentry will begin to within 10 percent of the actual time. Unfortunately, reentering WebReentry is the period of return to Earth when a spacecraft passes through the atmosphere before landing. During reentry the spacecraft decelerates and is heated intensely due to the formation of a bow shock.Radio communication may be blacked out for several minutes … great white junction
