Yesterday, Japan’;s unmanned space freighter Kounotori 2, of the H-2 Transfer Vehicle class, intentionally entered Earth***217;s atmosphere where it crashed and burned after its two months mission supplying the International Spate Station –; with it a slew of junk off the space station was dumpe********>Attached to the H-2 Transfer Vehicle was also a sensor which measured and transmitted various data back to scientists of the plunging inferno headed straight into the Pacific Ocean。 The device is called Re-entry Breakup Recorder, or REBR for short – recorded temperature, acceleration, rotational rate and other data during the spacecraft’;s high dive into Earth’s atmosphere。 The REBR device didn’;t need to be recovered, but data analysis could take 6 to 8 weeks to get successfully processed。

“REBR collected data during the breakup of the Kounotori 2 vehicle and successfully ‘;phoned home’; that data prior to final impact,” said William Ailor, Director of the Center for Orbital and Reentry Debris Studies at The Aerospace Corporation in El Segundo, Calif。 “In fact, it is still transmitting while floating in the ocean。”

In a touching gesture, while the Kounotori 2 was still docked, ISS astronauts tried to share their sympathy for the Japanese people, who are still suffering greatly from the March 11 double catastrophe, by putting three paper cranes in the cargo spaceship they hand made。

“;These are our extraterrestrial cranes, a symbol of hope, put into HTV for all Japanese people,”; the astronauts wrote in a message accompanying the photos。 “;We are with you!”;

The Kounotori 2 was a freighter operated by JAXA, the Japanese space agency, which is a major player in the $100 billion International Space Station project。 Japan built the orbiting structure’;s largest laboratory, called Kibo (“;Hope”;)。
