lead time

With less lead time, researchers could use a combination of multiple deflections, larger spacecrafts, or boosts in speed, depending on the hazardous object.

Yet “even though that sounds like it’s far away . . . it doesn’t necessarily give us a ton of lead time,” Bettwy said.

"Those who have past experiences with tornados reported that they needed fewer than 15 minutes to prepare when a warning was issued, but those without that experience wanted more lead time to prepare," Armstrong said.

The Alliance had argued there was not enough lead time for the industry to adjust to a sudden implementation.

“We simply didn’t have the lead time as we did for the men’s games,” she said.
