NASA Prepping Lean for
Orion Test Planned at Cape Canaveral Spaceport (Source:
Space Daily)
With the arrival of the Orion crew module to be used in the Ascent
Abort-2 test at Johnson Space Center in Houston, the team is already at
work with a lean, iterative development approach to minimize cost and
ensure the flight test stays on schedule. The approach involves
considering how to do things differently, finding ways to execute
elements of the buildup more efficiently and pushing on the norms of
doing business to see if there are areas where productivity can be
enhanced.
Shuttle heritage hardware, such as pyrotechnic control cards that
otherwise were not being used, are being integrated into flight designs
which allows the team to avoid building or building everything new.
Flight and ground software architectures have been evolved from other
development projects.
Engineers involved in outfitting the crew module simultaneously are
being trained to be flight controllers who will supervise the test when
it launches from Cape Canaveral Air Force Station in Florida. Since the
engineers involved in the work are extremely knowledge about the
vehicle's systems, they are being trained as operators and builders at
the same time. The crew module will return to Johnson in September and
be mated with the separation ring before the two elements are then
tested together and shipped to Kennedy Space Center in December. (3/7)
Griffin: DOD 'Mission
Assurance' Focus Raises Space System Costs (Source: Space
News)
The new head for research and engineering in the Defense Department
says he wants to change the Pentagon's approach to procurement. Mike
Griffin, the former NASA administrator who was sworn in as Under
Secretary of Defense for Research and Engineering last month, said at a
conference Tuesday that the department takes too long to develop new
systems and has too many people involved on them. That applied to space
systems in particular, he said: "We've trapped ourselves in a vicious
cycle of spending a lot of money on mission assurance which makes the
assets incredibly expensive." (3/6)
Verification/Qualification
Efforts Could Slow NASA Exploration Systems Completion
(Source: Space News)
Simultaneous development of exploration and commercial crew systems
could result in a "bottleneck" of safety and other reviews, a panel
warned. NASA's Aerospace Safety Advisory Panel, meeting last week,
identified no major new safety issues with the SLS and Orion programs
or the two commercial crew vehicles under development. However, they
said "a wall of verification and qualification processes" could strain
the limited number of NASA personnel responsible for them, which could
slow down the programs. The panel also said NASA should find "prudent
and safe ways" to shorten the time between the first and second SLS
missions after NASA elected not to fund construction of a second mobile
launch platform. (3/6)
BlackSky Constellation's
First Satellite Ready for Launch (Source: Space News)
The first satellite for the BlackSky constellation of Earth-imaging
satellites is complete and ready for launch. Seattle-based Spaceflight
Industries said Tuesday that the Global-1 satellite is the first of
four that the company plans to launch in the next year on U.S. and
foreign launch vehicles. The satellite, capable of taking images at a
resolution of one meter, will be part of an eventual constellation of
60 satellites Spaceflight is developing in a partnership with Thales
Alenia Space and Telespazio. (3/6)
Russian Company Plans
Suborbital Space Tourism Flights (Source: Tass)
A Russian company says it plans to start offering suborbital
spaceflights in the mid-2020s. CosmoCourse is developing a rocket and
capsule that would carry six passengers and one crewmember on a
suborbital flight, with an estimated ticket price of $250,000. The
company said development of the system will cost an estimated $150-200
million, which it is attempting to raise. (3/6)
Lessons From the Tunguska
Event (Source: Space Daily)
Russia's state emergency center has shared some of the most worrisome
scenarios that presumably await planet Earth in the decades to come,
and, most importantly, outlined how dangerous the contact with
celestial bodies might turn out. Large asteroids of up to one kilometer
in diameter are feared to come into dangerous proximity to Earth in the
coming years, "Antistikhiya" center of Russian Emergency management
ministry said. Up till 2050, we are expecting 11 events of asteroids
approximating Earth closer than the average lunar orbit radius, which
is 385 thousand kilometers. The objects vary in size from seven to 945
meters." (3/7)
Embry-Riddle Researchers
Eye Buckypaper for Keeping Astronauts Safe in Inflatable Habitats
(Source: Space Daily)
At first, inflatable habitats in orbit around Earth may sound like a
dangerous idea, given that the vacuum of space is littered with, as
NASA says, "millions of pieces of human-made debris or space junk
consisting mainly of fragmented rocket bodies and spacecraft parts
created by 50 years of exploration." Imagine the consequences of a
micrometeoroid or a piece of space junk half that size, moving at
22,000 miles per hour as it strikes an inflatable space habitat.
A team of Embry-Riddle Aeronautical University faculty and graduate
student researchers is helping NASA answer questions about the
feasibility of humans living in these structures beyond the Earth's
grasp. Their research focuses on developing and refining smart material
sensors that are used to detect stress or damage in critical
structures, such as automobile motors or the wings of aircraft. They
are creating a new generation of sensors using a type of carbon
nanotubes called buckypaper that is sensitive enough to detect the
impact of even the smallest micrometeoroids.
What if thousands of these tiny sensors could be used to coat a large
flexible membrane on, say, an inflatable habitat in space? They might
more accurately monitor strain to the structure and pinpoint impacts
from nearly invisible micrometeoroids. (3/7)
