Russia to Reduce Launches of Progress
Spacecraft to Three a Year as of 2016 (Source: Itar-Tass)
The annual number of launches of cargo spacecraft Progress will be
reduced to three a year from four as of 2016, the new draft of the
federal space program for 2016-2025 says. In 2018 and 2019 one Progress
spacecraft will be launched not from Baikonur, in Kazakhstan, but from
the new spaceport Vostochny, currently under construction.
Under the new program the dates for re-equipping the orbital cluster of
socio-economic and research satellites of a new generation are
postponed by two to five years. (4/24)
Russia's New Orbital Station to Have
Five Modules (Source: Itar-Tass)
A new Russian orbital station, which will likely replace the
International Space Station and which is expected to consist of three
modules in the initial phases of the project, will be augmented with
convertible and energy modules by 2016, says a revised draft of the
Federal Space Program slanted for the years 2016 through to 2015.
Earlier reports said an agreement on extending the operational life of
the International Space Station through to 2024 had been reached. In
2017, Russia will augment its segment at the ISS with a laboratory
module. Other appendages to the ISS will come in the form of an orbital
node in 2018 and a research energy unit in 2019. No decisions on the
destiny of the ISS after 2024 have been taken so far and the Russian
side does not rule out it will separate its three new modules from the
orbital complex to set up a national orbital station on their basis.

What Would Happen if There Were a War
in Space (Source: Vice)
DOD officials announced that the Pentagon is looking for $5.5 billion
to build up its space defense systems by 2020, Air Force Secretary
Deborah Lee James straight up admitted that, looking at the layout of
modern space exploration, the US now believes it's facing new and
evolving threats to everything it owns above earth. This isn't just
bluster from one corner of the government.
This year, Congress urged the Secretary of Defense and Director of
National Intelligence to start studying offensive space weapons in
addition to defensive systems. The US and Soviets saw that putting a
nuclear weapon in orbit would be hugely destabilizing. There was a
nuclear test called Starfish Prime [in 1962] that set off a 1.2 megaton
nuclear warhead in low-earth orbit and it killed like a third of the
satellites in orbit at the time, including a couple of American
satellites.
So everyone quickly realized that setting off nuclear detonations in
orbit was not going to be a good idea.... The next level up would be
the kinetic attacks, where you're trying to destroy or damage the
object. Some of those might not have a big effect. If you had a laser
that was powerful enough to burn a hole through a critical part of a
satellite to render it inoperable, the satellite itself wouldn't be
useful, but it wouldn't explode into a whole bunch of debris. Click here.

A human colony on Mars could be just 25 years and several steps away.
Fifty-one Purdue University students in a senior spacecraft design
class this year compiled a 1,000-plus page report detailing the
resources and actions necessary to colonize Mars by 2040.
The students used famed astronaut Buzz Aldrin’s book as a jumping off
point. In “Mission to Mars: My Vision for Space Exploration,” Aldrin
focuses on the small accomplishments needed to work toward a permanent
colony, such as first establishing a base on the moon and on Phobos,
one of two moons orbiting Mars.
“The class works as a single team to achieve a specified space mission
goal, which in this past I have dictated as the customer,” professor
James Longuski said. “This time was a little different. ... In this
particular project, the students were given a unique opportunity to
work with Buzz Aldrin and his concepts for colonizing Mars.” (4/23)

NASA IG Scrutinizes Seldom-used Plum
Brook Test Facilities (Source: Space News)
All but one of the five big test facilities at NASA’s Plum Brook
Station in Sandusky, Ohio, have few or no customers, and the situation
is unlikely to change any time soon, according to an April 23 report
from NASA’s inspector general (IG).
A “majority of the test facilities are underutilized, with the level of
use and funding for these facilities depending on NASA programs and
external customers choosing to perform testing at Plum Brook rather
than at other NASA or private facilities,” the IG wrote in the 28-page
report, “Audit of NASA’s Requirements for Plum Brook Station.”
Some of the facilities, most of which date back to the 1960s, are so
rundown they require millions of dollars in repairs — costs that must
be borne by prospective customers who show no sign of materializing,
the IG wrote. The inspector general recommended NASA create a long-term
strategy for either maintaining or disposing of underutilized
infrastructure at Plum Brook. (4/24)

NASA May Have Accidentally Created a
Warp Field (Source: Mysterious Universe)
NASA and other space programs were working on prototypes of the EmDrive
or RF resonant cavity thruster invented by British aerospace engineer
Roger J. Shawyer. This propulsion device uses a magnetron to produce
microwaves for thrust, has no moving parts and needs no reaction mass
for fuel. In 2014, Johnson Space Center claimed to have developed its
own low-power EmDrive.
Which brings us to today’s warp field buzz. NASA has a tool to measure
variances in the path-time of light. When lasers were fired through the
EmDrive’s resonance chamber, it measured significant variances and,
more importantly, found that some of the beams appeared to travel
faster than the speed of light. If that’s true, it would mean that the
EmDrive is producing a warp field or bubble. Here’s a comment from a
space forum following the tests. (4/24)
Can Nuclear Waste Help Humanity Reach
for the Stars? (Source: Planetary Society)
The heat from the plutonium is able to keep essential systems warm and
to also be converted to electricity using the thermoelectric Seebeck
effect. With a half-life of 87.7 years, the plutonium has the potential
to provide heat and electricity for well over a century. However,
making plutonium-238 is expensive and difficult. You need a reactor
with the right neutron flux and a supply of neptunium-237 feedstock to
produce the plutonium.
You also need a small nuclear reprocessing plant to separate the
plutonium chemically from the highly radioactive fuel. Over the years,
plutonium-238 has been produced by a number of countries including the
USA, Russia, and the UK. Historically, some material has even been used
to provide the electrical power in heart pacemakers. In the case of
plutonium for space applications, stocks of the material are now
running low.
The USA is restarting production, but the current stocks and production
rate in the near term are unlikely to be high enough to support the
broad range of space missions that the US science community might wish
to target. In Europe, without the neptunium-237 feedstock and necessary
processing facilities, the production of plutonium-238 is considered
too expensive. As a consequence, Europe has decided to focus on an
accessible alternative material that could power future spacecraft:
americium-241. (4/23)
