number one, they are awesome.
eles são incríveis.
a new thing about the universe,
algo novo sobre o Universo,
de uma nova maneira.
a um novo entendimento
milhares de pessoas e 44 anos
from an idea into orbit.
em órbita a partir de uma ideia.
todos os dias, não desistir.
because I live it.
essa escolha, porque eu a vivo.
almost all the time and still keep going,
quase o tempo todo e ainda sigo em frente,
os telescópios são construídos.

but on the light sensor,
mas no sensor de luz,
by a team that I joined
no Jet Propulsion Laboratory da NASA.
that this sensor would work really well
para detectar o gás hidrogênio.
very, very expensive sensors
the machine I was using

there were other challenges,

again and again and again and again;
executamos testes inúmeras vezes;
least expect them:

o melhor dia da história desse projeto.
this was the greatest day
em agosto de 2017, que não deu certo,
in the New Mexico desert.
no deserto do Novo México.
lançar o telescópio.
my whole life -- into this project,
toda a minha vida, nesse projeto,
that that happened.

right around sunset on that day
próximo ao pôr do sol naquele dia
e a Lua quase cheia.
e tenho vontade de chorar,
these balloons are spherical,
esses balões são esféricos,
in the New Mexico desert,
I thought to myself,
about why since that day.
desde aquele dia.
has been full of things
tem sido repleto de coisas

were a reason for them to give up.

that discovery is mostly a process

Why you should listen
Dr. Erika Hamden is a professor of astrophysics at the University of Arizona. Her observational focus is on measuring and mapping diffuse hydrogen around galaxies and within star forming regions in our own galaxy. Her current projects include FIREBall, a UV balloon-borne telescope; KCRM, a spectrograph for the Keck telescope; and Hyperion, a UV space telescope she is currently developing. Her work is driven by a desire to know and understand more about the universe around us.
Hamden received a bachelor's from Harvard in 2006 and a PhD from Columbia in 2014, both in astrophysics. She has held an NSF Astronomy and Astrophysics Postdoctoral Fellow and the R.A. and G.B. Millikan Prize Postdoctoral Fellow in Experimental Physics at the Caltech. She was awarded a Nancy Grace Roman Technology Fellowship for her detector work in 2016. She worked as a chef for a year before beginning grad school and has a serious yoga practice.
