in space there is very little resistance from lack of gravity so they get literally no exercise in space and they can lose muscle mass and bone density. also space suits are hard to move in.
If your water rocket leaks, it will not be able to build up enough pressure to launch properly. This could result in a failed launch or a weak trajectory. It is important to ensure that your water rocket is properly sealed before each launch to achieve the best performance.
Liquid Hydrogen and Liquid Oxygen are delivered to launch complex 39 for loading directly into the external fuel tank several hours before a scheduled launch.
The Launch Room is a set of rooms used for preparing a tribute before they are entered into the arena.
It is a little burnt but the launch pad is designed to take extreme heat and pressure created by the space shuttle. If it wasn't, they would have to make a new launch pad every launch and those things are worth a pretty penny...
The Space Shuttle Challenger was delayed multiple times before its tragic launch on January 28, 1986. Initially, the launch was scheduled for November 1985 but faced several postponements due to technical issues, weather conditions, and scheduling conflicts. Overall, the Challenger experienced at least five significant delays before its final launch attempt.
Astronaut training takes years before an individual is selected for a particular mission. Astronauts prepare for that launch day with a series of medical tests to ensure they are healthy for the launch and are expected to stay healthy through the mission. They then begin to acclimate themselves to a new time schedule based on launch time. They spend the final day or two at the Kennedy Space Center in simple crew quarters and have a meal together before suiting up several hours before launch.
T means the Time of launch -- when the launch is planned to happen. T minus is the number of seconds before the rocket is to launch. T minus four seconds and counting means it is four seconds in the sequence of event before launch will occur and progressing toward that launch. T minus four seconds and holding means it is four seconds before launch in the sequence of events that precede launch and the progress toward launch has stopped. The hold/delay can be most any length of time, but once counting begins again it will still be four seconds until launch -- that is, they pick up where they left off and continue toward launch.There are both planned holds (to give everyone time to evaluate things) and unplanned holds when something is wrong. After launch it becomes T plus so many seconds. Actions during launch happen so many seconds after launch. For example, on a Space Shuttle launch, the Solid Rocket Boosters will separate from the Shuttle at T plus so many seconds.
(C) china was successful in their first satellite launch, which occured before the United States could launch their first satellite.
No, they didn't, they had a slight romantic relationship but Launch disappeared before anything could happen, Tien was never really interested anyway.
Rockets are typically attached to the launch pad using a system of hold-down bolts or clamps that secure the rocket in place. These mechanisms are released at liftoff to allow the rocket to launch. Additionally, there are umbilical connections between the rocket and the launch pad for fueling, power, and communication before launch.
The Apollo 13 crew trained for several months before the actual launch into space. They underwent extensive simulations and training exercises to prepare for the mission.
