‘Impossible’ EmDrive Attracts Rising
Attention, Even From Skeptics (Source: Economist)
For years, space geeks have been intrigued by the idea of propulsion
systems that don’t need propellant – and now one of the best-known
concepts, known as the EmDrive – is getting a serious once-over. The
EmDrive, short for electromagnetic drive, could be revolutionary for
spaceflight if it works. Spaceships could dispense with the mass of
rocket fuel, and because the velocity builds up progressively, trips to
Mars and beyond would be much faster and simpler.
The concept involves bouncing microwaves around a closed cavity that’s
shaped like a cone. The shape supposedly funnels the microwaves to
generate forward thrust. “Given the costs – low – of a ground test that
should produce extraordinary evidence, it would seem very reasonable to
me to pay for two or three independent experimentum cruccii at the
national laboratories,” Pournelle wrote. “Yes, they have other
important work to do (or should), but constructing an EmDrive is within
the capabilities of any university physics department and some high
schools.” (12/30)
Brazilian Satellite Manufacturer Seeks
New Business (Source: Space News)
In the absence of a guaranteed order for a second geostationary
satellite, Brazil’s emerging domestic satellite manufacturer Visiona
Tecnologia Espacial is building up a remote sensing business and
weighing a small satellite project in order to gain more experience.
Established in 2012, Visiona is a joint venture between Telebras
Telecomunicações Brasileiras and Embraer Defense and Security tasked
with cultivating a geostationary satellite manufacturing capability in
Brazil. The company’s flagship project is the Geostationary Defense and
Strategic Communications (SGDC) satellite. (12/30)
Will a President Trump Change NASA’s
Mars Goals? Sen. Bill Nelson Says No (Source: Miami Herald)
Turmoil with Russia and uncertainty with how Donald Trump will
“refocus” the U.S. space program is having no effect on NASA’s goal of
getting humans to Mars, U.S. Sen. Bill Nelson is telling anyone who
will listen. During a recent stop in Tallahassee, the lone statewide
elected Democrat in Florida, chided reporters for not asking more about
the space program and the nation’s efforts to explore Mars.
“It is my interest to see that NASA doesn’t miss a beat,” under the
Trump administration, Nelson told reporters. He re-affirmed plans to
get humans to Mars by 2033 and another to have a new American rocket to
take U.S. astronauts to space within the next two years. “We’re well on
our way,” said Nelson, who is the highest ranking Democrat on the
Senate Commerce, Science and Transportation Committee with jurisdiction
over NASA. (12/29)
The Year of Milestones in Space
(Source: CNBC)
Whatever you think of life on Earth in 2016, it was a year of
milestones for space. Space travel companies made technical leaps, NASA
reached Jupiter, and great discoveries were made. There were also
high-profile failures and sad moments, as great scientists and
astronauts left Earth forever. Here are a few of the highlights.

Space Colonies Will Start Out Like the
Wild West, Grow Family-Friendly (Source: Space.com)
As humans explore other worlds, the colonies they develop may change
over time. While the first settlements may rely on individuals, as the
outposts grow more self-sustaining, families will likely become the
colonists of choice, a panel of experts said.
"The socioeconomic origins of colonists are going to change over time,"
science fiction author Charles E. Gannon told Space.com. "Trailblazers
will be specialists; so will true pioneers. However, once you move to a
settler model, things will change to a more normalized selection
demographic," Gannon said.
Initially, space colonization may function a great deal like the
American West. The first forays into the wilderness were made by
travelers like Lewis and Clark, individuals who cut their way across
the country to map it for those who stayed behind. The intrepid
explorers had to carry their own supplies, all fabricated back home.
The panel likened this sort of exploration to visits to the moon and
Mars by small groups of astronaut explorers. (12/30)
Satellite Constellations Could be
Poised to Challenge the Broadband Industry (Source: LA Times)
It’s been more than a decade since a handful of ambitious entrepreneurs
saw their plans to provide global telecommunications service through
massive satellite constellations blow up, doomed by runaway costs. Now,
a new generation of satellite entrepreneurs is headed back to the
launch pad. Backed by billions of dollars from deep-pocketed investors,
they plan to blanket the earth in the next few years with perhaps
thousands of miniature satellites beaming cheap, ubiquitous broadband
service.
What’s different? Launching one of these smaller satellites can cost a
fraction of the price for a larger, school-bus-sized satellite. These
new satellites will largely be mass-produced. And consumers now
demand high-speed Internet connectivity pretty much everywhere, on
airplanes, cruise ships and in the remotest village in Africa.
Companies such as SpaceX, OneWeb and Boeing have all recently proposed
networks of satellites in low-Earth orbit to provide high-speed
broadband access around the globe. (12/30)
Russia Plans 29 Space Launches in 2017

Deputy Prime Minister and head of Roscosmos supervisory committee
Dmitry Rogozin said Wednesday 23 launches are planned in 2017.
"Twenty-nine space launches are planned in 2017, there may be
unscheduled [launches]," the corporation's TV station said. Roscosmos
has not officially disclosed its projections. (12/30)
