Capsule’sDescent toEarth

When it approachesEarth, the OSIRIS-REx spacecraft will not decrease as it makes its sample drop-off.Instead, when it reaches63, 000 miles( or102,000 kilometers) aboveEarth’s surface area– about one-third the range fromEarth to the(******************************************************************************************************************************************************************************************* )– a message from operators on the ground will activate the pill’s release, and the pill will be sent out spinning towards the environment listed below.(***************************************************************************************************************************************************************** )minutes after the drop-off, the spacecraft will fire its thrusters to divert pastEarth towards asteroidApophis, where it will continue examining our planetary system under a brand-new name: OSIRIS-APEX (OSIRIS-Apophis Explorer). -9 LfN0

Meanwhile, after zooming through area for 4 hours, the pill will pierce Earth’s environment at 8: 42 a.m. MDT (10: 42 a.m. < period class ="glossaryLink" aria-describedby ="tt" data-cmtooltip ="<div class=glossaryItemTitle>EDT</div><div class=glossaryItemBody>EDT is an abbreviation for Eastern Daylight Time, the time zone for the eastern coast of the United States and Canada when observing daylight saving time (spring/summer).

A heat guard will assist to control the temperature level inside the pill, keeping the sample safe at a temperature level comparable to that ofBennu’s surface area.

Capsule’sDescent toEarth

Parachutes will bring the pill’s descent to a safe landing speed. A drogue parachute created to supply a steady shift to subsonic speeds will release initially, about 2 minutes after the pill goes into the environment. Six minutes later on– at about 1 mile (1.6 kilometers) above the desert– the primary chute will unfurl, bring the pill the remainder of the method to a 36- mile by 8.5-mile (58- kilometer by 14- kilometer) location on the military variety. At goal, the pill will have slowed to about 11 miles per hour (18 kph).

Finally, simply 13 minutes after getting in the environment, the pill will be on Earth for the very first time in 7 years, waiting for the healing group’s method.

About 20 minutes prior to the pill lands, when it is still high above the veil of Earth’s environment, the healing field group will board 4 helicopters and go out into the desert. The infrared radiance of the pill’s heat signature will be tracked by thermal instruments up until the pill ends up being noticeable to optical instruments, providing the healing group a method to trace the pill’s Earthbound course. The objective for the healing group is to recover the pill from the ground as rapidly as possible to prevent polluting the sample with Earth’s environment.

Sample Processing and Distribution

Once situated and packaged for travel, the pill will be flown by means of helicopter longline to a momentary tidy space on the military variety, where it will go through preliminary processing and disassembly in preparation for its journey by airplane to NASA’s Johnson Space Center in Houston, where the sample will be recorded, taken care of, and dispersed for analysis to researchers worldwide.
