A Reentry Breakup Recorder (REBR) is a device that is designed to be placed aboard a
spacecraft
A spacecraft is a vehicle or machine designed to spaceflight, fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including Telecommunications, communications, Earth observation satellite, Earth ...
to record pertinent data when the spacecraft (intentionally) breaks up as it
re-enters Earth's atmosphere.
The device records data regarding the thermal, acceleration, rotational and other stresses the vehicle is subject to. In the final stages it transmits the data back to a laboratory before it is destroyed when it hits the surface.
History
Two REBRs were launched in January 2011
[ on the Japanese ]Kounotori 2
Kounotori 2 (こうのとり2号機, "white stork" ), also known as HTV-2, was launched in January 2011 and was the second flight of the Japanese H-II Transfer Vehicle to resupply the International Space Station (ISS). It was launched by the H ...

The ''Johannes Kepler'' ATV, or Automated Transfer Vehicle 002 (ATV-002), was an uncrewed cargo spacecraft built to resupply the International Space Station (ISS). It was launched on February 16, 2011 by the European Space Agency (ESA). ''Johanne ...
,[ which reentered Earth's atmosphere on 21 June 2011.
The Kounotori 2 vehicle re-entered on 30 March 2011. Its REBR successfully collected and returned its data; it survived the impact with the ocean and while floating continued to transmit. It took between 6 and 8 weeks to analyze the data.]
The second unit was intended to collect data during the reentry of the Johannes Kepler ATV
The ''Johannes Kepler'' ATV, or Automated Transfer Vehicle 002 (ATV-002), was an uncrewed cargo spacecraft built to resupply the International Space Station (ISS). It was launched on February 16, 2011 by the European Space Agency (ESA). ''Johanne ...
(ATV-2); however the device failed to make contact after reentry and consequently no data was retrieved.
Two other units were used successfully for Kounotori 3
Kounotori 3 ( ja, こうのとり3号機; English: "white stork" ), also known as HTV-3, was the third flight of the Japanese H-II Transfer Vehicle. It was launched on 21 July 2012 to resupply the International Space Station (ISS) aboard the H ...
for its reentry on September 14, 2012, and Edoardo Amaldi ATV
The ''Edoardo Amaldi'' ATV, or Automated Transfer Vehicle 003 (ATV-003), was a European uncrewed cargo spacecraft, named after the 20th-century Italian physicist Edoardo Amaldi. The spacecraft was launched by the European Space Agency (ESA) ...
(ATV-3) on October 3, 2012.
Predecessor technology: image documentation of reentry and breakup
Earlier data collection from reentry and breakup was mostly visual and spectrograph
An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify mat ...

The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continen ...

On 5 September 2008, ''Jules Verne'' undocked from the ISS and maneuvered to an orbital position below the ISS. It remained in that orbit until the night of 29 September.[

At 10:00:27 UTC, ''Jules Verne'' started its first de-orbit burn of 6 minutes, followed by a second burn of 15 minutes at 12:58:18 UTC. At 13:31 GMT, ''Jules Verne'' re-entered the atmosphere at an altitude of , and then completed its destructive re-entry
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 entr ...
