The 17-year mission of the Tropic Rainfall Measuring Mission (TRMM) ended last April 8. This is a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA) to study rainfall necessary for weather and climate research.

NASA said that it cannot predict the exact time when and location where the spacecraft may enter the earth’s atmosphere but TRMM’s orbit brings it 35 degrees North latitude and 35 degrees South latitude and this may include the Philippine territory. It also said that the spacecraft’s uncontrolled re-entry will result to burning up most of its parts. It has been closely monitored since the end of its mission by the U.S. Space Surveillance Network, operated by the Department of Defense U.S. Strategic Command’s Joint Space Operations Center (JSpOC).

Debris of NASA Spacecraft may Fall in The Philippines Territory
The spacecraft has a mass of about 5,800 lbs and NASA assured the people that it will never cause serious threat since 96% of it will never reach the earth. This is in order to eradicate fear. It added that, "The chance that a piece of the spacecraft will strike a person is approximately 1 in 4,200. This means that if the re-entry happened 4,200 times, we could expect that one person would be harmed."
NASA also gave an assurance that what is left of the spacecraft that will re-enter the earth is made up of titanium and non-toxic. Any debris found should be reported to the authorities. It should not be touched because it has sharp edges.
