"T-minus" nghĩa là gì?

"T-minus" = T trừ -> nghĩa là khái niệm do NASA nghĩ ra để đếm ngược từ 10 trở xuống các sự kiện lớn/nhỏ, dù là phóng tên lửa, hay số ngày cho đến cuối tuần.

Ví dụ

In case you haven’t heard, it been 41 years now. That’s one more year than Moses wandered the desert. We are T-Minus 36 hours until the kickoff against Alabama. At the risk of never getting another table at Spurrier’s Gridiron Grille, you should cheer for Georgia Monday night. Why not? I mean, Alabama’s won about 21 national championships since Nick Saban arrived. It needs another trophy like Elon Musk needs another billion dollars.

The United States Space Force inaugural T-Minus 10-Miler will lift-off from Cape Canaveral Space Force Station next year, Dec. 10, 2022. This 10-mile race will be a part of the Space Force birthday celebration each year, and will take place surrounded by space launch history, at Cape Canaveral SFS. “Cape Canaveral is quite literally where space launch started for the United States,” said Brig. Gen. Stephen Purdy, Space Launch Delta 45 Commander. “We look forward to thousands of runners enjoying stepping through history, as they ponder the past, future, and get lost in space as we do.” Cape Canaveral Space Force Station and Patrick Space Force Base were the first locations to be re-designated as Space Force installations, Dec. 9, 2020, adding to the notable relevance of the USSF T-Minus 10-Miler location.

It was the first place I rented after moving out of my childhood home, a tiny house before they became fashionable: a closet-sized living room, a bedroom barely big enough for my bed, a bathroom the size of one you’d find on an airplane and a kitchen where you could reach everything by standing in one spot and turning in a circle. For a single guy, it was perfect. But even a tiny house needs occasional cleaning, and suddenly the clock was ticking: T-minus one hour until mom arrived. I stepped outside and took a couple of deep, cleansing breaths, then went back in to evaluate the indoor smells — the faint scent of a new bar of Irish Spring wasn’t enough to offset the musty smell of laundry in need of washing and the memory of last night’s chili.
