An unmanned Atlas V rocket will launch a powerful new broadband internet satellite into orbit from Florida today (Dec 18) and you can watch the action live online.
Built for satellite operator Hughes, EchoStar 19 (also known as Jupiter 2) is being touted as the company's most powerful internet communications satellite to date.
Hughes representatives said in a statement that EchoStar 19 "will be able to will provide significantly more capacity than EchoStar XVII (EchoStar 17), which was also built by SSL and launched in 2012.
"Current weather forecasts predict a 70 percent chance of favorable conditions for today's Atlas V launch.
The United Launch Alliance Atlas V rocket will launch the EchoStar XIX (or EchoStar 19) from a pad at Florida's Cape Canaveral Air Force Station at 1:27 p.m. EST (1827 GMT).

Last year the United Nations set a goal of eliminating extreme poverty worldwide by 2030.
From space, at night, mild and extreme poverty look the same—dark.
Researchers have tried to work around this limitation by searching nighttime satellite images for unusually dark areas.
“Places lit up at night are generally better off,” explains Marshall Burke, an assistant professor of earth science systems at Stanford University.
But this method is imperfect, especially for differentiating between grades of poverty.

Researchers need to actually photograph a potentially Earth-like planet to learn more about it.
We called our mission Project Blue because we're hoping to find another blue planet in Earth's neighboring star system.
Ten years ago, scientists didn't know if Earth-like planets were common in this galaxy.
An illustration of habitable zones around different stars: Planets are plotted based on their orbital distance compared to Earth's and their star's mass compared to the sun's.
Project Blue contributed this article to Space.com's Expert Voices: Op-Ed & Insights.

They have also built a soundproof room in which multiple marmosets with the electrical stimulation devices can run around and interact with one another.
Common marmosets (Callithrix jacchus) are social and communicative in captivity, unlike the macaque that is more commonly used as a model primate.
Wang hopes that marmosets will improve researchers’ understanding of the evolution of communication and help them refine devices such as cochlear implants for deaf people.
And one of the world’s largest manufacturers of cochlear implants, Advanced Bionics in Valencia, California, is now beginning to test its next-generation devices in the marmosets.
The researchers found that the electrical stimulation failed to activate many of the neurons that respond to sound, including some involved in pitch perception.
