WebThis will be first time in Apollo that crews have flown 'lift vector Up' during reentry. Normally, lift vector is Down. However, we want to extend the range by 215 miles [400 km] so for a short period, about a minute and 24 - 25 seconds during the blackout period, the spacecraft will be flown with lift vector Up. Web10 apr. 2011 · Answer. Dave - The main reason why things heat up when they hit the Earth's atmosphere is they've got huge amounts of kinetic energy - they're going incredibly fast. When they bash into the Earth's atmosphere, most of the heating is actually because the air they bash into hasn't got time to get out of the way, so the air gets compressed; and ...
