Early reentry-vehicle concepts visualized in shadowgraphs of high speed wind tunnel tests. 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 meteors remains cold, and the erosion is due, to a large extent, to chipping or cracking of ...
The primary goal was to have the RV change its path during reentry so that anti-ballistic missiles (ABMs) would not be able to track their movements rapidly enough for a successful interception. The first known example was the Alpha Draco tests of 1959, followed by the Boost Glide Reentry Vehicle (BGRV) test series, ASSET [16] and PRIME. [17]
The Space Shuttle (and prior program) flight controllers worked relatively brief periods: The several minutes of ascent, the few days the vehicle was in orbit, and reentry. The duration of operations for Space Shuttle flight controllers was short and time-critical. A failure on the Shuttle could leave flight controllers little time for talking ...
Edwards Air Force Base in California was the site of the first Space Shuttle landing, and became a back-up site to the prime landing location, the Shuttle Landing Facility at the Kennedy Space Center. Several runways are arrayed on the dry lakebed at Rogers Dry Lake, [6] and there are also concrete runways. Space shuttle landings on the lake ...
The Space Shuttle Columbia was lost as it returned from a two-week mission when previously detected damage to the shuttle's thermal protection system (TPS) resulted in the spacecraft breaking apart during reentry at an altitude of just under 65 km and a speed of about Mach 19. Investigation revealed that a piece of foam insulation had fallen ...
In April, the FAA ended the practice of allowing commercial flights to apply for a reentry license in orbit — with reentry missions only subject to approval if they had less than a 1-in-10,000 ...
The minimum temperature the countdown may proceed at was determined by a table of temperatures determined by wind speed and relative humidity ranging from 36 °F (2 °C) (high humidity, high winds) to 48 °F (9 °C) (low humidity, low winds). In no case was the space shuttle to be launched if the temperature was 35 °F (2 °C) degrees or colder.
Space Shuttle Endeavour landing from orbit on STS-126, its 22nd spaceflight Reusable spacecraft are spacecraft capable of repeated launch, atmospheric reentry, and landing or splashdown. This contrasts with expendable spacecraft which are designed to be discarded after use.
