The few car­bon-rich as­ter­oids cir­cling our sun might hold the pre­cur­sors to life on Earth, lit­tle changed over the mil­len­ni­ums. That’s why the OSIRISREx space­craft blasted to­ward them late last year. The 20-foot-long ex­plorer has spent the in­ter­ven­ing time po­si­tion­ing it­self for a grav­ity-as­sisted sling­shot around our pale blue dot. Next year, it will si­dle up to the as­ter­oid Bennu and ex­tend its arm to col­lect sam­ples.
