Internal NASA emails reveal that an asteroid kind of snuck up on them
“Because there may be media coverage tomorrow, I’m alerting you that in about 30 mins a 57-130 meter sized asteroid will pass Earth at only 0.19 lunar distances (~48,000 miles),” wrote Lindley Johnson, NASA’s planetary defense officer, in a July 24 email alert sent to other space agency experts. “2019 OK was spotted about 24 hrs ago.”
