All-Electric Satellites
Prove a Tough Sell (Source: Space News)
Orbital Sciences Corp.’s new GeoStar-3 satellite product, which offers
a 60 percent increase in power and a one-third increase in payload mass
compared to the GeoStar-2, will use electric power for in-orbit station
keeping but not for orbit-raising, Orbital Chief Executive David W.
Thompson said. He said satellite operators have shown little demand for
an all-electric satellite mainly because it would take months, rather
than a week, to reach final geostationary operating position.
The satellite industry has gone two years since Satmex of Mexico and
Asia Broadcast Satellite (ABS) of Hong Kong joined forces to inaugurate
Boeing Space and Intelligence Systems’ all-electric 702SP product with
a four-satellite order. Since then, no more all-electric satellites
have been contracted despite what satellite builders, operators and
launch service providers describe as a wave of interest in the
technology. (3/10)
Maine Company's Rocket
Research Eyes Lower-Cost Space Launches (Source: Maine Biz)
Space flight is a big idea dominated by big numbers and big
corporations. But Karl Hoose, president of Applied Thermal Sciences in
Sanford, thinks his company can help bring down the cost of getting
into orbit. "There's a slew of different technologies and businesses
that would come from having cheaper access to space, and that's the
whole goal for us," Hoose says.
To get into a low Earth orbit, a launch vehicle needs to reach around
17,500 mph, roughly 24 times the speed of sound. Typically, that's done
with massive rockets carrying tons of fuel and liquid oxygen, which can
weigh up to eight times as much as the fuel. In the ATS facility,
engineers are working to refine technology that would create the launch
vehicle with a 50-pound payload capacity at a cost of $4,500 per pound
payload, and in the process serve a niche for smaller, more affordable
space vehicles.
Hoose plans to cut that system out of the equation as much as possible
by getting about one minute of propulsion from special jet technology
that, at high speeds, runs off of air in the atmosphere, reducing the
need for onboard fuel. Hoose projects ATS can deliver a launch vehicle
90% smaller and 85% lighter than a conventional all-rocket propelled
vehicle. (3/11)
How India Got an
Indigenous Cryogenic Engine (Source: Live Mint)
The GSLV program was started by ISRO in response to India’s mounting
communications needs. By 1987, the government had approved the
development of the second generation INSAT-2 series of satellites,
weighing more than 2 tonnes. ISRO wanted to develop a 2.5-tonne class
of satellites and put them into a geostationary transfer orbit at
36,000km from Earth’s surface.
ISRO also wanted to make a vehicle that would be bigger, lighter and
more efficient than its workhorse Polar Satellite Launch Vehicle
(PSLV). There were three fuels options: earth storable, semi-cryogenic,
and cryogenic. It was then that ISRO thought of procuring cryogenic
engines from other countries. After rejecting offers from the US and
France for both the sale of engines and transfer of technology, India
approved an offer by Russia in 1990.
India sent eight scientists to Moscow to work with Soviet scientists.
They worked there for 15 months, but did not have access to everything.
Eventually, in 1993, Glavkosmos backed out of the deal and revoked the
transfer of cryotechnology agreement. Under a renegotiated deal, Russia
decided to provide four fully functional engines and two mock-ups. It
also agreed to supply three more cryogenic engines at a cost of $9
million. Click here.

Long-Term Warming Likely
to Be Significant Despite Recent Slowdown (Source: NASA)
A new NASA study shows Earth's climate likely will continue to warm
during this century on track with previous estimates, despite the
recent slowdown in the rate of global warming. This research hinges on
a new and more detailed calculation of the sensitivity of Earth's
climate to the factors that cause it to change, such as greenhouse gas
emissions.
Drew Shindell, a climatologist at NASA's Goddard Institute for Space
Studies in New York, found Earth is likely to experience roughly 20
percent more warming than estimates that were largely based on surface
temperature observations during the past 150 years. Global temperatures
have increased at a rate of 0.22 Fahrenheit (0.12 Celsius) per decade
since 1951. But since 1998, the rate of warming has been only 0.09 F
(0.05 C) per decade -- even as atmospheric carbon dioxide continues to
rise at a rate similar to previous decades.
Carbon dioxide is the most significant greenhouse gas generated by
humans. Some recent research, aimed at fine-tuning long-term warming
projections by taking this slowdown into account, suggested Earth may
be less sensitive to greenhouse gas increases than previously thought.

Space Launch System (Source: Aviation Week)
NASA still wants to build the heavy-lift Space Launch System, and as
long as Sen. Richard Shelby is alive, it will. The U.S. space agency
needs the Alabama Republican, who is the ranking member of his party on
the Senate Appropriations Committee, and he needs the SLS to keep his
constituents at the Marshall Space Flight Center happy. So the fairly
level funding of $1.3 billion for the big rocket, plus some extra
advanced-technology money, in the agency's fiscal 2015 budget request
is no surprise.
SLS received $1.6 billion in fiscal 2014, with no serious challenges on
Capitol Hill despite continued grumbling from other space
constituencies—“New Space” and science for starters—that could use that
kind of money for their own purposes. The project is bending serious
metal. In an effort to broaden their own constituent base, managers at
Marshall have been seeking other payloads for the SLS, so far with no
apparent good news.
A U.S. Air Force/National Reconnaissance Office analysis is said to
have turned up no requirement for a Saturn V-class launch vehicle
except—being the military—the need to sustain the U.S. industrial base
for big rockets. The Science Mission Directorate certainly would be
able to use a heavy-lifter for a robotic outer-planet mission, both to
avoid time- and money-consuming gravity-assist routes to distant
targets and to carry more radioisotope thermoelectric generators for
more power to run its instruments. But those would be
multibillion-dollar flagship-class missions, and the money is not
there. (3/10)

Arianespace: Cheaper by
the Dozen (Source: Aviation Week)
Arianespace says it delivers cargo to the Space Station for less than
NASA is currently paying SpaceX and Orbital Sciences under a pair of
Commercial Resupply Services (CRS) contracts worth a combined $3.5
billion. Clay Mowry of Arianespace says the Ariane 5 rocket and
Automated Transfer Vehicle (ATV) have launched more than 24,000 kg of
food, supplies, fuel and water to the ISS with four ATV missions at a
cost of roughly $460 million each, or $76,500 per kilogram.
“That’s more cargo than SpaceX’s entire 12-flight resupply contract
with NASA,” Mowry said. “We would be happy to take over their contract
and lower the price per kilogram for delivering cargo to the ISS.”
Mowry was responding to a Feb. 20 comment by Elon Musk, who said
Arianespace would go bankrupt if it had the SpaceX CRS contract. Musk's
comment was aimed at criticism from Arianespace and other European
space-industry officials that SpaceX charges considerably more to its
government customers than the $56.6 million it advertises for
commercial missions.
SpaceX services cost NASA about $80,000 per kilogram. Orbital's cost to
NASA is about $95,000 per kilogram. However, unlike ATV and Cygnus, the
recoverable Dragon cargo vessel has the unique ability to return cargo
and experiments to Earth. The company's first two CRS missions,
launched in October 2012 and March 2013, returned a combined 1,969 kg
of cargo mass from the orbiting outpost, a service ATV and Cygnus cargo
vehicles cannot provide. (3/10)

How Fleets of 'Flat

The approach represents a radical departure from the

big-ticket landers or rovers that cost hundreds of millions of dollars
to design and build. The two-dimensional lander idea "gives you the

MIT Team Proposes Fuel
Stations for Future Missions (Source: Space.com)
Future lunar missions may be fueled by gas stations in space, according
to MIT engineers: A spacecraft might dock at a propellant depot,
somewhere between the Earth and the moon, and pick up extra rocket fuel
before making its way to the lunar surface. Orbiting way stations could
reduce the fuel a spacecraft needs to carry from Earth - and with less
fuel onboard, a rocket could launch heavier payloads, such as large
scientific experiments.
Over the last few decades, scientists have proposed various designs,
such as building a fuel-manufacturing station on the moon and sending
tankers to refill floating depots. But most ideas have come with hefty
price tags, requiring long-term investment. The MIT team has come up
with two cost-efficient depot designs that do not require such
long-term commitment. Both designs take advantage of the fact that each
lunar mission carries a supply of "contingency propellant" - fuel
that's meant to be used only in emergencies.
In most cases, this backup fuel goes unused, and is either left on the
moon or burned up as the crew re-enters the Earth's atmosphere.
Instead, the MIT team proposes using contingency propellant from past
missions to fuel future spacecraft. For instance, as a mission heads
back to Earth, it may drop a tank of contingency propellant at a depot
before heading home. (3/10)

Plasma Plumes Help Shield
Earth From Damaging Solar Storms (Source: Space Daily)
The Earth's magnetic field, or magnetosphere, stretches from the
planet's core out into space, where it meets the solar wind, a stream
of charged particles emitted by the sun. For the most part, the
magnetosphere acts as a shield to protect the Earth from this
high-energy solar activity.
But when this field comes into contact with the sun's magnetic field -
a process called "magnetic reconnection" - powerful electrical currents
from the sun can stream into Earth's atmosphere, whipping up
geomagnetic storms and space weather phenomena that can affect
high-altitude aircraft, as well as astronauts on the International
Space Station.
Now scientists at MIT and NASA have identified a process in the Earth's
magnetosphere that reinforces its shielding effect, keeping incoming
solar energy at bay. By combining observations from the ground and in
space, the team observed a plume of low-energy plasma particles that
essentially hitches a ride along magnetic field lines - streaming from
Earth's lower atmosphere up to the point, tens of thousands of
kilometers above the surface, where the planet's magnetic field
connects with that of the sun. (3/10)

NASA to Look for Signs of

Europa has geysers spewing material from what appears to be a

in that cold, dark sea. Scientists have long dreamed of sending a
robotic probe to Europa, and they have put such a mission at the top of
their wish list. But Europa is a hard target: It’s very close to
Jupiter, and a spacecraft and its instruments would need extra
shielding to keep them from being fried in Jupiter’s harsh radiation
environment.
The initial estimate of the cost of putting a spacecraft into orbit
around Europa was a wince-
inducing $4.7 billion. Engineers then came up with a cheaper
alternative, in which the spacecraft would go into an orbit around
Jupiter that would send it past Europa dozens of times. During these
flybys it could sample the material ejected by the geysers, looking for
signatures of life in the ocean below the moon’s icy crust. That might
