Dragon Ball Inspired Collection [in Polyvore here]. I had this in my drafts over there for a while and decided to post them. Special mention to the wallet in Vegeta’s set and the pouches in Bulma’s and 18′s, I had fun with those. The list of all items is over there in Polyvore.
We sent three suborbital sounding rockets
right into the auroras above Alaska on the evening of March 1 local time from the Poker Flat Research Range north of Fairbanks, Alaska.
Sounding rockets are suborbital rockets that
fly up in an arc and immediately come back down, with a total flight time
around 20 minutes.
Though these rockets don’t fly fast enough to
get into orbit around Earth, they still give us valuable information about the
sun, space, and even Earth itself. Sounding rockets’ low-cost access to space
is also ideal for testing instruments for future satellite missions.
Sounding rockets fly above most of Earth’s
atmosphere, allowing them to see certain types of light – like extreme
ultraviolet and X-rays – that don’t make it all the way to the ground because
they are absorbed by the atmosphere. These kinds of light give us a unique view
of the sun and processes in space.
Of these three rockets, two were part of the
Neutral Jets in Auroral Arcs mission, collecting data on winds influenced by
the electric fields related to auroras. Sounding rockets are the perfect
vehicle for this type of study, since they can fly directly through auroras –
which exist in a region of Earth’s upper atmosphere too high for scientific
balloons, but too low for satellites.
The third rocket that launched on March 1 was part
of the ISINGLASS mission (short for Ionospheric Structuring: In Situ and
Ground-based Low Altitude Studies). ISINGLASS included two rockets designed to
launch into two different types of auroras in order to collect detailed data on
their structure, with the hope of better understanding the processes that
create auroras. The initial ISINGLASS rocket launched a few weeks earlier, on Feb. 22, also from the Poker
Flat Research Range in Alaska.
Auroras are caused when charged particles
trapped in Earth’s vast magnetic field are sent raining down into the
atmosphere, usually triggered by events on the sun that propagate out into
Team members at the range had to wait until
conditions were just right until they could launch – including winds, weather,
and science conditions. Since these rockets were studying aurora, that means
they had to wait until the sky was lit up with the Northern Lights.
Regions near the North and South Pole are
best for studying the aurora, because the shape of Earth’s magnetic field
naturally funnels aurora-causing particles near the poles.
But launching sensitive instruments near the
Arctic Circle in the winter has its own unique challenges. For example, rockets
have to be insulated with foam or blankets every time they’re taken outside –
including while on the launch pad – because of the extremely low temperatures.
The Auction House revamp is launching Sunday, March 19 @ 08:00 server time. To prepare for the launch, we will be shutting down and clearing out the current version of the Auction House on Saturday, March 18 @ 22:00 server time.
During the time between these two events, the Auction House will be inaccessible.
Soaring through the skies! This view looks from the window of our F-18 support aircraft during a 2016 Orbital ATK air-launch of its Pegasus rocket.
The CYGNSS mission, led by the University of Michigan, will use eight micro-satellite observatories to measure wind speeds over Earth’s oceans, increasing the ability of scientists to understand and predict hurricanes.
CYGNSS launched at 8:37 a.m. EST on Thursday, Dec. 15, 2016 from our Kennedy Space Center in Florida. CYGNSS launched aboard an Orbital ATK Pegasus XL rocket, deployed from Orbital’s “Stargazer” L-1011 carrier aircraft.
Pegasus is a winged, three-stage solid propellant rocket that can launch a satellite into low Earth orbit. How does it work? Great question!
After takeoff, the aircraft (which looks like a commercial airplane..but with some special quirks) flies to about 39,000 feet over the ocean and releases the rocket.
Blasted with sound, shaken for hours and pyro
detonated, the Orion Service Module Completes Ground Tests at our Glenn
We recently completed a structural
integrity evaluation on the test version of the Orion service module at our
Plum Brook Station in Sandusky, Ohio. Designed to ensure the module can
withstand launch atop the Space Launch System (SLS) rocket, the battery of
tests was conducted in stages over a 16-month period.
The 13-ton European service module will power, propel and cool Orion, while supplying vital oxygen and water to its crew during future missions.
The Powerhouse: Space Launch System and Orion
Our Space Launch
System is an advanced launch vehicle that will usher in a new era of human
exploration beyond Earth’s orbit. SLS, with its unparalleled power and
capabilities, will launch missions to explore deep-space destinations aboard
our Orion spacecraft.
What is Orion? Named after one of the largest
constellations in the night sky and drawing from more than 50 years of
spaceflight research and development, the Orion spacecraft will be the safest,
most advanced spacecraft ever built. It will be flexible and capable enough to
take astronauts to a variety of deep destinations, including Mars.
Welcome to the Buckeye State
In November 2015, the full-sized test version
of the Orion service module arrived
at Cleveland Hopkins Airport aboard an Antonov AN-124. After being unloaded
from one of the world’s largest transport aircraft, the module was shipped more
than 50 miles by truck to Plum Brook for testing.
Spread Your Wings
The first step of the service module’s ground
test journey at Plum Brook’s Space Power Facility, saw one of its 24-foot
solar array wings deployed to verify operation of the power system. The
test confirmed the array extended and locked into place, and all of the wing
mechanisms functioned properly.
Can You Hear SLS Now?
The SLS will produce a tremendous amount of
noise as it launches and climbs through our atmosphere. In fact, we’re
projecting the rocket could produce up to 180 decibels, which is louder than 20
jet engines operating at the same time.
While at the Reverberant Acoustic Test
Facility, the service module was hit
with more than 150 decibels and 20-10,000 hertz of sound pressure.
Microphones were placed inside the test environment to confirm it matched the
expected acoustic environment during launch.
After being blasted by sound, it was time to
rock the service module, literally.
Shake Without the Bake
Launching atop the most powerful rocket ever
built – we’re talking more than eight million pounds of thrust – will subject
Orion to stresses never before experienced in spaceflight.
To ensure the launch doesn’t damage any vital
equipment, the engineering team utilized the world’s
most powerful vibration table to perform nearly 100 different tests,
ranging from 2.5 Hz to 100 Hz, on the module in the summer of 2016.
Gotta Keep ‘Em Separated
The team then moved the
Orion test article from the vibration table into the high bay for pyroshock
tests, which simulated the shock the service module will experience as it
separates from the SLS during launch.
Following the sound, vibration and separation
tests, a second solar array wing deployment was conducted to ensure the wing
continued to properly unfurl and function.
Headed South for the Summer
The ground test phase was another crucial
step toward the eventual launch of Exploration Mission-1, as it validated
extensive design prep and computer modeling, and verified the spacecraft met
our safety and flight requirements.
