Whoooopppppeeeeeeeee!

I’m the James Webb Space Telescope and I’m on the wildest skedaddle of my young lifestyles. On Dec. 25, an Ariane 5 rocket shot me 870 miles above the Earth in half of an hour after which spit me out. I zoomed previous the Moon a pair of day and a half of later—twice as quick because it took these slowpokes on the Apollo mission—and now I’m on my device to my final destination: an orbit 1 million miles a long way from my home planet. It’ll carry me a cramped bit over a month to bag there.
After I attain, I’m going to be a photographer. I trust one of the best mirrors and the most magnificent cameras that any telescope has ever had, I will carry photography of the main galaxies that formed 13.5 billion years ago, and I would possibly perchance also search for for indicators of lifestyles in the atmospheres of planets orbiting round faraway stars. Nevertheless there’s loads I must attain ahead of I commence taking pictures my first photography.
It turned into pretty petite onboard the Ariane 5, so I had to fold myself up to match internal. Now that I’m in home, I sooner or later trust some room to stretch out. As soon as I left the rocket, I unfurled my solar panels, which is ready to offer me the gas I must work. About two hours after beginning, I assembled an antenna that I’ll direct to keep up a correspondence with some scientists serve home. Since then, they’ve been sending me directions about how to preserve out unfolding myself so I will sooner or later commence my mission.

In actual fact, the scientists serve home seem a cramped bit wired. They speak I’m in the course of my “29 days on the threshold,” after I’m performing my most complex maneuvers and there are over 300 techniques things would possibly perchance perchance shuffle execrable. It’s style of be pleased when NASA sent the Curiosity rover to Mars and all the scientists held their breath all the map thru the “seven minutes of alarm” because it landed on the skin—as an alternative of my component takes longer and is device extra advanced. Luckily, I will’t feel alarm for any minutes because of I’m a robotic.
Additionally fortunate: I already pulled off one of my most crucial early maneuvers, a rocket blast that helped me level myself in the licensed direction to reach my final orbit. Subsequent, I must make direct of 178 moderately a few mechanisms in precisely the licensed repeat to dwelling up two of my most crucial parts: my sunshield and my mirrors.
My sunshield will preserve me cool and block out sunlight, which is so intellectual that it would originate it inconceivable for my cameras to desire up the murky gentle from a long way away stars. The defend is constituted of 5 skinny layers of Kapton, a heat-resistant plastic, spread taut across four arms, style of be pleased a kite. My main replicate is 21 toes (6.4 m) across and is made of 18 hexagonal segments of beryllium, which is admittedly honest at maintaining its shape in wintry temperatures. My enormous replicate will scoop up all the starlight it will after which leap that gentle onto a series of three smaller mirrors that will succor focal level the sunshine onto my cameras.

There are loads extra duties increasing over the next two weeks, so I’ve made myself a to-attain list to succor preserve it all straight:
Dec. 28: I’ll unfolded the arms that preserve my sunshield and reflect up the panel that holds all my mirrors and sensors.
Dec. 30: I’ll build out a pair of cramped sails at the ends of my arms that will succor me maneuver as soon as my sunshield is utterly deployed; photons from the Solar will push against my defend ever so a cramped bit, so I must licensed my route each and each continuously to stay in the licensed space.
Jan. 1: I’ll commence spreading the 5 Kapton layers across my arms to preserve out developing the defend. It received’t be easy: The total meeting will trust 400 pulleys, 70 hinges, eight motors, and 1,312 toes (400 m) of cable. Nevertheless as soon as I’m done, I will commence engaged on my telescope.

Jan. 4: I’ll dwelling up a tripod in entrance of my enormous replicate. This tripod will preserve a 2nd, smaller replicate that will leap all the sunshine the immense replicate catches serve in direction of my cameras.
Jan. 5: I’ll dwelling up a tiny radiator in the serve of my telescope to chill off all my digicam tools.
Jan. 7: I’ll fold out the perimeters of my enormous replicate that I had to tuck in to slot in the rocket.
Then, over the next couple of weeks, my instruments will cool down and I’ll reach my final orbit 1 million miles a long way from Earth, about four times as a long way as the Moon. Within the intervening time, I’ll direct a series of motors to align all my replicate segments and sensors merely licensed to bag one of the best image. If all the pieces goes licensed, by Jan. 29, I’ll be ready to carry my first portray.
I’ll shuffle away out my time on earth, where I’ve been pampered for the previous quarter-century; scientists lavished $8.8 billion on me—about 10 times my fashioned funds—and I turned into having the kind of good time at the Goddard Space Heart that I made up my thoughts to stay round 14 years previous my fashioned 2007 beginning date. Nevertheless now that I’m sooner or later here, hurtling thru home, on the mission I turned into conceived for serve in 1996, I’m frankly merely too busy to alarm about remarkable else. When all here’s over, I’m looking out at for merely taking a breather and looking out at out at the cosmos. I will’t wait to advise their own praises you what I catch.
