After taking off on Mercury's last mission, Gordon Cooper settled down for a good night's sleep midway through his journey. Compared to most spaceflight tasks, it seemed (1) to be a fairly easy undertaking. But Cooper ended up tucking (2) (has to put) his hands under his safety harness to prevent his arms from floating (3) (floating) and hitting
(4) switches (knock) on the instrument panel. Since Cooper's flight, sleeping (5) (sleeping) in space has become a matter of course, perhaps too much. When performing an especially boring or exhausting task, some astronauts have fallen asleep, they just didn't really nod: they just closed their eyes and stopped moving (6) (moving). There are none of the waking mechanisms that we would expect (7) to have (have) on the ground: the head (8) fell (fell) to the side or a pencil (9) fell (fell) to the ground.
Space teams have also found that they don't need handholds or ladders to get around; They quickly learn (10) to push (push) with one hand and float straight to their destinations. (11) eating (eating), using a computer, or doing some other stationary task, astronauts now slide their gloved feet into loops or wedges stuck to the floor. Similarly, a single
The velcro head strap is sufficient (12) to prevent (13) sleeping astronauts (13) from exiting through the vents.
A favorite recreation in space is (14) playing (playing) with food.
Instead of putting food into their mouths with a utensil, some experienced astronauts like to (15) launch (catapult) food from spoons. Although (16) drinking (drinking) coffee seems the most natural thing on Earth, in space it won't work. If you tried (17) to tilt (tilt) the cup back to take a drink, the weightless coffee would not come out. One astronaut offers the following advice: "Don't let your curiosity tempt you to (18) seek (explore) a larger mass of liquid than you are willing to (19) take (drink) later." If you don't start (20) drinking (drink) your drop through a straw, it eventually sticks to the nearest wall or window.
Although spaceflight has its irritations, astronauts need to get high. The idea of airborne testing is to make (21) live (live) and (22) work (work) in weightlessness easy and uncomplicated for ordinary people.
