On October 20th, NASA’s OSIRIS-REx spacecraft gently touched the Bennu asteroid, let loose a gasp of air, and picked up the company’s first pattern of free-range asteroid rubble. However NASA is now racing to protected the pattern, as OSIRIS-REx’s assortment head is wedged open and slowly shedding subject material that it dared to take from a roaming house rock.
OSIRIS-REx introduced in 2016 to intercept and gather a pattern from the 1640-foot-wide Bennu asteroid. Its objective, to assemble no less than 60 grams of subject material from the distance rock, may facilitate analysis in chemistry, planetary science, and different big-brain topics. Whilst we now have quite a lot of meteorite samples, asteroids are “uncontaminated,” as they haven’t handed via our setting.
NASA could be very desirous about its 60-gram objective, or even deliberate to ship deficient OSIRIS-REx again to Bennu if it didn’t gather sufficient subject material. However the company is dealing with a distinct drawback. Photographs won October 23rd verify that the craft has an ok pattern, however it kind of feels that some asteroid particles are wedged within the assortment chamber’s mylar “lid.”
To forestall unfastened subject material from slipping out of the open assortment chamber, NASA is forgoing the “pattern mass dimension” task scheduled for Saturday, amongst different pieces at the OSIRIS-REx time table. For now, NASA will center of attention on stowing its treasured pattern in a Pattern Go back Pill, which is able to stay subject material secure because the craft returns to Earth.
NASA plans to offer OSIRIS-REx updates over the weekend. You’ll to find additional info at the company’s site.
