Commercial Space Exploration: No
Longer an Oxymoron! (Source: Space Review)
Last month, the X PRIZE Foundation awarded more than $5 million to five
teams competing in the Google Lunar X PRIZE for milestones they
achieved getting their landers ready for flight. Derek Webber, one of
the judges of those prizes, argues that these prizes are themselves a
milestone for a more commercial approach for space exploration. Visit http://www.thespacereview.com/article/2692/1

The Gift of a Europa Mission May Have
a Cost (Source: Space Review)
NASA's 2016 budget proposal, released last week, included plans to
formally start work on a project to send a mission to Jupiter's moon
Europa. Jeff Foust reports that while this is good news for mission
advocates, that decision could have a funding catch. Visit http://www.thespacereview.com/article/2691/1

Quantum Equation Predicts Universe Has
No Beginning (Source: Phys.org)
The universe may have existed forever, according to a new model that
applies quantum correction terms to complement Einstein's theory of
general relativity. The model may also account for dark matter and dark
energy, resolving multiple problems at once.
The widely accepted age of the universe, as estimated by general
relativity, is 13.8 billion years. In the beginning, everything in
existence is thought to have occupied a single infinitely dense point,
or singularity. Only after this point began to expand in a "Big Bang"
did the universe officially begin. Click here.

How to Get Into Space for Cheap—Use a
Balloon (Source: Medium)
Hurling an object into space is certainly dramatic and risky. During
its flight, a giant rocket burns hundreds of tons of fuel in a
continuous explosion full of sound and fury, signifying human triumph
over gravity. All that power is dangerous. If the controlled explosion
gets out of hand, people die and millions of dollars of equipment
disintegrates into shrapnel. But no other technology can loft heavy
payloads—like warheads and spacecraft—into orbit.
However, if you want to lift lighter loads, or ascend slowly to
moderate altitudes, another method holds promise for safer, cheaper
trips into space. Improbable as it sounds, a rocket can hitch a ride on
a balloon. Balloon-launched rockets, or “rockoons,” sound crazy. Rocket
scientist and entrepreneur José Mariano Lopez-Urdiales agrees.
“Sometimes crazy is good,” he says. “If it sounds normal, everyone’s
doing it.” Click here.

What if an Asteroid Was About to Hit
Earth? (Source: Space Safety)
Sci-fi movies that depict Earth’s near destruction from incoming
asteroids like Armageddon or Deep Impact are seen as “scary
entertainment” far from reality. After all, the giant asteroid that
wiped out the dinosaurs was 66 million years ago. Most people think if
there is something like this to worry about it is safely millions of
years away.
Unfortunately this is faulty logic for several reasons. First we have
recently found that asteroid strikes on Earth are 4 to 10 times more
likely that we thought just a decade ago. Secondly, we now have many
more people that 10 or 20 years ago. These are concentrated in cities
and dependent on modern infrastructure, so a single asteroid hit of
just modest size could kill millions and make tens of millions suddenly
vulnerable.
We will soon have 50 mega-cities of over 10 million people and global
population could hit anywhere from 10 to 12 billion by 2100). Thirdly,
we have to protect against not only a “ten” on the Torino Impact Hazard
Scale — such as the K-T event that wiped out 80% of all species on
Earth — but also something like a “6” or above strike that could still
wipe out a mega-city and do enormous damage. Click here.

The Space Economy (Source:

The OECD Space Forum provides a definition of global space economy that
comprises the space industry’s core activities in space manufacturing
and in satellite operations and other consumer activities that have
been derived over the years from governmental R&D. It includes all
public and private factors involved in developing, providing and using
space-related outputs, space derived products and services and the
scientific knowledge arisen from space research. Click here.

Reusable Launch Vehicles: An Indian
Perspective (Source: Space Safety)
Launching satellites or humans to space is a costly affair. Since man
stepped on moon, it has been the constant dream of engineers,
policymakers and others among the space community to develop and design
a vehicle that can be used for multiple launch missions, like an
aircraft, whether military or transport. The only success achieved so
far is the Space Shuttle Program that has been shelved in 2011.
The Indian Space Research Organization (ISRO) announced on January 7th,
2015, that they will perform a RLV technology demonstration in March.
If successful, this test will be a big achievement for India and ISRO,
and will cement its position as a forerunner in the field of space
exploration. Click here.

DSCOVR Launch Date Now Set for Feb. 10
(Source: SpaceFlight Insider)
The next launch attempt for the DSCOVR mission will now be Tuesday,
Feb. 10 at 6:05 p.m. EST with a backup launch opportunity on Wednesday,
Feb. 11 at 6:03 p.m. EST. Weather for an attempt on Monday, Feb. 9 is
unfavorable. If an attempt was made and ultimately scrubbed for
weather, the team would lose either the Tuesday or Wednesday launch
opportunity due to crew rest requirements for the Air Force. (2/9)
Can Jet Planes Launch Small Satellites
on the Cheap? (Source: Space Daily)
Launching a satellite is an expensive endeavor. Rockets must be built
-- often only to be obliterated upon re-entry or wrecked as they splash
back into the ocean. And massive amounts of fuel must be expended to
propel the heavy metal objects through Earth's atmosphere. It's a
problem for both private communication companies and the federal
government.
But problem solvers at the U.S. Defense Advanced Research Projects
Agency are working on a solution -- the Airborne Launch Assist Space
Access (ALASA) program. Military engineers working on the program want
to use a small and efficient propellant system launched from a jet
plane (not a large rocket blasted from a launch pad), to spring
satellites weighing up to 100 pounds into low Earth orbit. Click here.

ULA Has Backup Engine Plan for NextGen
Atlas (Source: Decatur Daily)
"Engines are tough," says ULA's Tory Bruno. "Rockets are hard in
general, and the engine is probably the most complex thing on a launch
vehicle of the nature we build. [Although we've selected Blue Origin's
engine as our first choice,] we have a backup plan," he says.
"Aerojet Rocketdyne (which has a Huntsville facility) also has come
forward with a rocket engine that is very attractive in its technology
and its performance. They're a couple of years behind Blue. We're going
to bring them both along parallel for at least a couple more years
until it's clear. Now I fully expect Jeff Bezos and Blue Origin to
succeed, but I wouldn't be doing my job if I didn't manage that risk by
having this backup plan." (2/7)
Australia Sending Satellites to Space
to Get Internet to the Outback (Source: Mashable)
The Australian government is taking connectivity to new heights, with
the launch of two satellites into space to provide Internet access to
regional Australia. The company behind the government's National
Broadband Network (NBN) announced work on its 10 satellite ground
stations is complete. Each station will comprise of two 13.5-meter
satellite dishes and are situated in New South Wales, Western
Australia, Queensland, Tasmania and South Australia.
Following a recent report putting Internet speeds in Australia at 44th
in the world, it is hoped the next-generation Ka-band satellite
technology will bring 400,000 households in the bush up to speed with
their city counterparts. The first satellite is planned for an October
or November 2015 launch, with the second following a few months later.
