Story summary

Johns Hopkins University researchers report Deinococcus radiodurans survives 1 to 3 gigapascals, supporting lithopanspermia.
The study observed 100% survival at 1.4 gigapascals and 60% at 2.4 gigapascals.
The testing equipment failed first.
The findings raise questions about life's origins.
The findings necessitate a review of planetary protection protocols for missions to Mars and Phobos.
