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

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.

Students at Dixon Elementary students think strategically as they

learn to play chess, participate in book studies, Scrabble Club,

Robotics Club, Girls on the Run Club, Boys' Running Club, Academic

Derby, Recycling Club (recently recognized by the National Council of

Keep America Beautiful as the leading public school in recycling),

Odyssey of the Mind (world competitors two out of the last three

years), Science Fair competitors (Regional, State and National

champions), and Science Olympiad.

ARISS is an international educational outreach program partnering

the participating space agencies, NASA, Russian Space Agency, ESA,

CNES, JAXA, and CSA, with the AMSAT and IARU organizations from

participating countries.

ARISS offers an opportunity for students to experience the

excitement of Amateur Radio by talking directly with crewmembers on-

board the International Space Station. Teachers, parents and

communities see, first hand, how Amateur Radio and crewmembers on ISS

can energize youngsters' interest in science, technology, and

learning. Further information on the ARISS program is available on

the website
