Successful launch of KickSat carrying 104 Sprite satellites
Five CubeSats including KicksSat which carries 104 Sprite satellites
on 437 MHz were successfully launched by the SpaceX CRS-3 mission on
Friday, April 18 at 19:25:22 UT.
Zac Manchester KD2BHC says:
After a beautiful launch KickSat was deployed in low Earth orbit. We
at Cornell and several amateur radio operators around the world have
made contact with the spacecraft and it is alive and well. I can’t
thank all of you enough for your tremendous support over the past two
years. Thank you for believing in KickSat!
This is the culmination of a lot of hard work and is a huge
milestone, but we’re not done yet. In 16 days the Sprites will deploy
from KickSat. We need as many people as possible listening in, so if
you’re interested, please check out the wiki and our mailing list for
more information. As always, don’t hesitate to contact me with
questions.
The CubeSats KickSat, SporeSat, TSAT, PhoneSat-v2.5 and ALL-
STAR/THEIA were deployed into a 325×315 km 51.5 degree inclination
orbit.
All the Sprites operate on a single frequency of 437.240 MHz and use
Code Division Multiple Access (CDMA). The transmitter runs 10 mW
output of Minimum Shift Keying (MSK) modulated binary data with each
data bit modulated as a 511 bit Pseudo-Random Number (PRN) sequence.
The ITU emission designator is 50K0G1D.
The KickSat CubeSat has downlinks on 437.505 MHz and 2401-2436.2 MHz.

Space-X Dragon Cargo Craft set to dock with ISS
A Dragon cargo craft stuffed with science and supplies is
approaching the International Space Station for an automated laser-
guided final approach Sunday, culminating with grapple by the
outpost's robotic arm shortly after 7 a.m. EDT (1100 GMT).
The SpaceX-owned spaceship is carrying about 4,600 pounds of cargo
to reinforce the space station's stocks of research experiments, crew
provisions and spare parts.
Since launching Friday at 3:25 p.m. EDT (1925 GMT), the Dragon
spacecraft has fired its Draco thrusters to adjust its orbit to match
that of the space station, setting up the final rendezvous sequence.
By about 2:30 a.m. EDT (0630 GMT), the Dragon spacecraft will be
about 28 kilometers, or 17 miles, below and behind the space station.
At that range, the Dragon should be within range of a UHF
communications panel the space station's crew can use to issue simple
commands to the supply ship in the event of a problem.
Several height-adjustment and midcourse correction rocket burns will
fine-tune Dragon's rendezvous, guiding the ship into position 350
meters, or about 1,150 feet, directly beneath the space station at
5:13 a.m. EDT (0913 GMT).
The Dragon will initially rely on relative GPS navigation data to
guide its approach to the space station. Once directly beneath the
complex, its computers will switch to laser and thermal sensors.
Dragon carries a laser guidance sensor package and two thermal
cameras to aid its final rendezvous with the space station.
Before leaving the initial hold point 1,150 feet beneath the space
station, the cargo craft will conduct a 180-degree yaw maneuver to
align its grapple fixture with the position of the space station's
robot arm.
Soon after beginning its final approach sequence, the Dragon
spacecraft will halt again at a hold position 250 meters, or 820
feet, below the space station. This brief hold allows ground
controllers to assess the status of the rendezvous and issue a "go"
for the Dragon to enter the so-called keep-out sphere, an imaginary
circle around the space station in which traffic is tightly
controlled for safety reasons.
The timeline calls for the Dragon spacecraft to depart the 250-meter
hold point around 5:39 a.m. EDT (0939 GMT), pausing again at a 30-
meter hold position before pressing on to a final point about 10
meters, or 33 feet, beneath the space station.
Arrival at the final hold point is scheduled around 6:56 a.m. EDT
(1056 GMT).
Astronauts Koichi Wakata and Rick Mastracchio will monitor the final
phase of the Dragon's approach, including manning the space station's
robotic arm to grapple the free-flying cargo craft. Grapple is
scheduled for 7:14 a.m. EDT (1114 GMT). Once the Dragon is firmly
snared by the robotic arm, the 58-foot Canadarm will move the capsule
into position for berthing with the Earth-facing port on the space
station's Harmony module around 9:45 a.m. EDT (1345 GMT).

KickSat Project Announces Telemetry Download Competition
Zac Manchester, KD2BHC, of the KickSat project is offering prizes to
the first stations to copy telemetry from KickSat and the "Sprite"
satellites it will deploy.
"I'll be offering prizes to the first several people who receive
telemetry packets from KickSat as well as the first few who receive
signals from the Sprites," the Cornell University aerospace
engineering graduate student has announced. "The prizes will include
souvenir Sprites, and CRS-3 and ELaNa-V mission patches."
KickSat's Zac Manchester, KD2BHC, offers a whimsical boost to the
delayed SpaceX launcher at Cape Canaveral.
The KickSat will go into space with the third SpaceX ISS resupply
mission, which was delayed at least until April 18. If all goes
according to plan, the 3U KickSat CubeSat subsequently will release
more than 100 Sprite satellites -- each about the size of a small
cracker -- into orbit. They will become the smallest Earth-orbiting
satellites ever.
For KickSat telemetry (437.505 MHz and 2401-2436.2 MHz), Manchester
wants the raw hex or ASCII packet data, "and I have to be able to
successfully decode it." For the Sprites, he wants a raw baseband
recording, "and I have to be able to decode at least one Sprite
signal from it." All of the Sprites are on the same frequency --
437.240 MHz. Manchester said he is the final judge on winners, and
he'll continue to offer prizes, "until I run out of cool swag." To
get in on the fun, Manchester said, visit the KickSat Wiki and sign
up for the KickSat mailing list.

Space-X supply ship begins journey to space station
SpaceX's commercial Dragon supply ship thundered into orbit Friday
to begin a two-day pursuit of the International Space Station,
setting up the delivery of 2.4 tons of fresh supplies and
experimental cargo to the 450-ton research complex Sunday.
The Dragon spacecraft, flying on SpaceX's third operational resupply
run to the space station, lifted off at 3:25:21 p.m. EDT (1925:21
GMT) from Cape Canaveral's Complex 40 launch pad, initially rising
slowly as its Falcon 9 rocket powered up to more than 1 million
pounds of thrust.
The launcher picked up speed, breaking the sound barrier about 70
seconds after liftoff and rocketing through the stratosphere before
releasing its nine-engine first stage less than 3 minutes into the
flight.
The first stage fell away, leaving the upper stage's single Merlin
1D engine to accelerate the rocket and Dragon payload into orbit as
the vehicle flew northeast from Cape Canaveral, paralleling the U.S.
East Coast to reach the space station's exact orbital inclination.
The 12-foot-diameter first stage was programmed to ignite its
engines two times during its fall back into the Atlantic Ocean,
slowing its velocity before deploying four landing legs made of
carbon fiber and aluminum honeycomb.
Friday's launch was the first Falcon 9 rocket to fly with landing
legs.
Elon Musk, SpaceX's CEO and chief designer, posted an update Friday
night on Twitter saying the first stage made a good landing despite
high waves in the recovery zone a few hundred miles northeast of Cape
Canaveral.
"Data upload from tracking plane shows landing in Atlantic was good!
Several boats enroute through heavy seas," Musk tweeted, adding a few
minutes later that the first stage's flight computers continued
transmitting for 8 seconds after reaching the water, an indication
the rocket must have splashed down with minimal damage.
SpaceX says the experimental first stage recovery is a stepping
stone toward reusing the Falcon 9 rocket, which Musk says is critical
for reducing the cost of space transportation.
While the first stage's return maneuvers garnered much attention
during a post-flight press conference Friday, the mission's primary
goal is to resupply the space station, reinforcing the orbiting
outpost's dwindling food inventory and delivering fresh experiments
for researchers.
"I'm feeling pretty excited," Musk told reporters in a telephone
call from SpaceX headquarters in Hawthorne, Calif. "This is a happy
day. Most important of all is that we did a good job for NASA ...
Everything else is secondary to that."
The mission is SpaceX's third resupply run to the space station,
coming after successful flights in October 2012 and March 2013 to
kick off the execution of a $1.6 billion logistics contract with
NASA. Signed in December 2008, the deal covers 12 missions for the
delivery of a cumulative 44,000 pounds of cargo to the space station.
After reaching orbit Friday, the Dragon spaceship deployed from the
Falcon 9's second stage about 10 minutes after liftoff, receding from
the view of an on-board "rocketcam" backdropped by the muted blue
colors of the ocean splashed against the stark blackness of space.
The spacecraft automatically unfurled two power-generating solar
arrays with a wingspan of 54 feet.
SpaceX engineers initially ran into a problem with the Dragon
spacecraft's propulsion system, causing the capsule to miss an
appointed engine burn to set up for its two-day chase of the space
station.
But Musk said the glitch, traced to an isolation valve, was bypassed
by the use of a backup valve and the cargo mission was on track to
reach the space station early Sunday.
Late Friday, the Dragon spacecraft opened its navigation bay door,
exposing the ship's laser and thermal guidance sensors to be used in
the final phase of its approach to the space station.
Controllers plan a series of orbit-raising burns over the next day-
and-a-half, leading to the arrival of Dragon in the vicinity of the
complex in the predawn hours Sunday, U.S. time.
The spaceship will approach the space station from below, eventually
pausing about 30 feet beneath the complex while astronauts Koichi
Wakata and Rick Mastracchio snare Dragon with a robotic arm.
Grapple is scheduled for 7:14 a.m. EDT (1114 GMT) to wrap up a 40-
hour rendezvous that began with the Falcon 9 rocket's launch Friday.
The Dragon spacecraft launched Friday sports several upgrades over
previous SpaceX cargo vehicles, nearly quadrupling the ship's
capacity for powered cargo. The modifications include additional
freezers for biological samples and redesigned cargo racks to
accommodate additional payloads, according to SpaceX.
The mission is also taking up research experiments in the Dragon's
unpressurized trunk for the first time. The passengers include a NASA
optical communications terminal to demonstrate high data-rate links
between the space station and the ground, along with a high-
definition camera suite to collect videos of Earth.
The payload packages will be mounted outside the space station by
the lab's Canadian-built robotics system.
Astronauts will manually remove items stowed inside the Dragon
spacecraft's internal section, including 1,576 pounds of science and
research gear, 1,049 pounds of crew provisions, 449 pounds of vehicle
hardware, and 271 pounds of spacewalk tools.
The Dragon will arrive with a fresh spacesuit for the space
station's six-person crew, a space age garden to demonstrate
vegetable growth in microgravity, and legs for Robonaut 2, a humanoid
robot launched on a 2011 space shuttle mission.
The space station will repack the Dragon spacecraft's pressurized
module with experiment samples and other hardware destined to return
to Earth. Dragon's departure and splashdown in the Pacific Ocean is
scheduled for May 18.

The STELAR Project 2014
The education and science charity STELAR has been active in
promoting radiocommunications in schools and colleges for over 20
years, as part of curriculum enrichment and personal and professional
development for teachers.
Through its specialist courses, it has achieved much notable success
in establishing radio clubs in schools and inspiring young people to
seek careers in science, electronics and industry. It has played a
major role in space and satellite communications in schools.
In 2013 it provided opportunities for satellite experiment by
offering SDR receivers to schools allowing them to participate in the
current series of FUNCUBE satellite experiments.
Now in 2014 STELAR is offering a new challenge to educators both
professional and Amateur. The phenomenal success of the Raspberry Pi
computer has opened up new opportunities and stimulated demand for
educational projects linking communications systems, via computers.
This year STELAR is seeking to support the very best of those ideas
by making available grants to educational groups, with projects
designed to stimulate experiments with radio linked computing.
Typically these might take the form of:
• Radio systems linked to but not exclusively, a Raspberry Pi,
computer.
• A detailed Teachers guide to the use and benefits of FUNCUBE or
similar satellite systems in schools,
• The creation of radio-science projects to aid teachers personal
and professional development.
Educational groups can apply for funding to develop a project of
their choice, by submitting ideas for consideration by June 30, 2014.
Groups should set out their aims and giving as much detail as
possible. Successful entries will be notified during the Autumn term.
Interested ? then make contact by visiting the STELAR website

Next planned event(s): Dixon Elementary School, Holly Ridge, NC
A direct contact with students at Dixon Elementary School, Holly
Ridge, NC, via NC4OC is a go for Mon 2014-04-21 18:05:53 UTC 41
deg. Watch for possible last minute schedule change due to SpaceX
operations.
Dixon Elementary School is located in a rural setting, with its
feeder communities North Topsail Beach, Sneads Ferry, Holly Ridge and
Surf City. Our community has seen sharp rises in the population of
retirees and young families both military and civilian. With the
deployment of large numbers of military personnel to Camp Lejeune,
New River Air Station, and MARSOC (Marine Special Operations Center)
at Stone Bay, the Dixon area continues to grow. Our school
population as of February 2014 is over 900 students. Dixon
Elementary is a Title 1 School with 38% of our students receiving
free or reduced meal benefits. Our student population consists of
81% white students, .09% American Indian, .06% Hispanic, 9% Black, 2%
Asian and .007% Pacific Islander.
Dixon Elementary was initially accredited by AdvancEd in 1978.
Students are served by highly qualified teachers in 38 regular
classrooms, three self-contained exceptional children's classrooms
and two pre-kindergarten classrooms. There are six highly qualified
resource teachers who also offer support to our large population of
exceptional children. Dixon Elementary is a charter member of the
National Elementary Honor Society and the Global Schools Network.
In the fall of 2012 Dixon Elementary implemented a STEM classroom
for instruction in science, technology, engineering and mathematics
for students in grades K-5. Students rotate through the STEM
classroom every 7 days. The STEM classroom teacher, a veteran science
and math teacher, provides hands-on science and math instruction and
project-based learning, including a variety of engineering projects.
Each year Dixon Elementary hosts a SPACE DAY for students in Pre-K
through 5th grade, with our community joining us in this spectacular
event.
