UK Space Mission - STRaND-1 Plans for Launch on February 25
A UK mission, jointly developed by the University of Surrey's Sur-
rey Space Centre (SSC) and Surrey Satellite Technology Limited
(SSTL), to send the world's first smartphone satellite into orbit,
is due to launch on February 25 from India on PSLV-C20. This launch
will also carry the ocean study spacecraft SARAL as well as satel-
lites carrying amateur radio payloads.
STRaND-1 will be the first UK CubeSat to be launched and has been
developed by talented space engineers and researchers at Surrey with
the majority of the design and developmental work being carried out
in their spare time. The build and test phase of the project has
been completed in just three months. At the heart of STRaND-1 is a
Google Nexus One smartphone with an Android operating system.
During the first phase of the mission, STRaND-1 will use a number of
experimental 'Apps' to collect data while a high-speed linux-based
CubeSat computer developed by SSC takes care of the satellite. During
phase two, the STRaND-1 team plan to switch the satellite's in-orbit
operations to the smartphone, testing the capabilities of a number of
standard smartphone components for a space environment. The satellite
will be commissioned and operated from the Surrey Space Centre's
ground station at the University of Surrey.
Being the first smartphone satellite in orbit is just one of many
'firsts' that STRaND-1 is hoping to achieve. It will also fly inno-
vative new technologies such as a 'WARP DRiVE' (Water Alcohol Resist-
ojet Propulsion Deorbit Re-entry Velocity Experiment) and electric
Pulsed Plasma Thrusters (PPTs); both 'firsts' to fly on a nanosatel-
lite. It is also flying a printed part - believed to be the first
to fly in space!
A software-based speech synthesiser will be included to pay homage
to the UOSAT family of satellites OSCAR 9 and 11, that were launched
in 1980 & 1982. There will be an amateur radio AX.25 packet radio
downlink on 437.575 MHz using data rates of 9k6 or 19k2 bps.

New Cuban Satellite Operators Now On-the-Air
Cuba's new amateur satellite group, Grupo de Radioaficionados para
Operaciones Satelitales, or GROS says this week two Cuban amateurs
have made their first satellite contact via SO-50. GROS Coordinator
Raydel, CM2ESP reported on the success of Pavel, CO7WT and Jose,
CM2XN, "This may look simple, but for a Cuban Ham this is a great
success which follows many weeks of antenna building, equipment
adjustments and learning, these two hams enjoyed their first success-
contact on an FM transponder satellite. They know there is a lot more
of operating skills to learn and they are very happy to do so."
Grupo de Radioaficionados para Operaciones Satelitales, loosely in-
terpreted as "Ham Radio Group for Satellite Operations", says this
reflects on the successful mentorship to get Cuban radio amateurs
on the satellites. Few Cuban hams have the required radio gear and
require a degree of inventiveness and perseverance to put their
technical skills to the test to acheive success.
The intial success of this small group of Cuban hams hopes to inspire
and train more hams to build their satellite stations, get on the air
and activate new grids.
GROS hosts a VHF net in the Havana Province twice monthly on Friday.
They are working on creating a monthly HF satellite net in the near
future. GROS continues to work with Cuban National Amateur Radio Fed-
eration, F.R.C., the Federaci=F3n de Radioaficionados de Cuba, on the
logistical arrangements to hold the first national meeting of Cuban
amateur satellite operators.
Raydel invites questions and comments to the group to be sent to any
members of the Coordination Board using these contacts:
+ CO6CBF, Hector, Vice-Coordinator (co6cbf@frcuba.co.cu)
+ CO7WT, Pavel, Technical Vice-Coordinator (pavel@conas.cu)
+ CM2ESP, Raydel, Coordinator (cm2esp@frcuba.co.cu)
A video of Hector, CO6CBF, at the 2012 AMSAT Space Symposium talking
about how a Cuban Ham operates via satellite can be found on YouTube:

ARISS School Contacts This Week
United Kingdom
--------------
An International Space Station school contact was successfully com-
pleted with participants at Breadalbane Academy, Aberfeldy, United
Kingdom on February 12. The contact was made with a telebridge be-
tween NA1SS and W6SRJ.
Breadalbane Academy is a rural school serving Highland Perthshire
in the heart of Scotland. The school has 700 pupils coming from
Aberfeldy, Pitlochry, Rannoch and Dunkeld. The students are very
interested in all aspects of the space program.
Manitoba, Canada
----------------
An International Space Station school contact was successfully com-
pleted with participants at Chief Peguis Junior High School, Winni-
peg, Manitoba, Canada on February 13. The contact was made with a
telebridge between NA1SS and VK5ZAI.
Chief Peguis Junior High is a grade 7-9 school with a population of
about 550 students and staff. In April of 2011 Chris Hadfield made
a personal appearance at the school to talk to the students. Those
grade 7 students at that time are currently grade 9 students and
they remember his visit. They feel they already have a personal con-
nection with him.
This coming week International Space Station school contacts are
planned on Tuesday and Friday with:
+ The 4th Dimotiko Scholeio Chaidariou, Chaidari (near Athens),
Greece. This will be a direct contact via J41ISS on Tuesday,
February 19 at 12:30 UTC.
+ The Uplands Elementary School, Penticton, BC, Canada, with a
telebridge via IK1SLD on Friday, February 22 at 19:36 UTC.
ARISS is requesting listener reports for these contact. Due to
issues with the Kenwood radio that are not fully understood at
present, the Ericsson radio is going to be used for this cont-
act. ARISS thanks everyone in advance for their assistance.
If you are in range the downlink is 145.800 MHz.

Israeli Students Speak with Canadian Astronaut in Space
JERUSALEM (http://www.algemeiner.com/) - Ninth grade physics stu-
dents at Hebrew University Secondary School (Leyada) in Jerusalem
spoke with Canadian astronaut Chris Hadfield, as he orbited the
Earth aboard the International Space Station (ISS) on Sunday, Feb-
ruary 3.
The Israeli high school students were the recent winners of the Ilan
Ramon Space Olympics hosted each year by the Ilan Ramon Foundation,
established in honor of Israel's first astronaut, Ilan Ramon. Ramon
perished in the Space Shuttle Columbia disaster with six other Amer-
ican crew members, when the shuttle disintegrated reentering to earth
10 years ago.
Out of the 2,000 students from across Israel who participated in the
Space Olympics, Leyada's 19-member team won first prize, for build-
ing a space platform to repair satellites and constructing a guest-
house in space.
The first prize granted the winning students a chance to speak with
Canadian astronaut Chris Hadfield, who recently spoke with public
school students in Ontario. According to Leyada's Reuben Tel-Dan,
the proud physics teacher who oversaw the project, "I believe that
Leyada is the first school in Israel to communicate with space."
The special event is part of NASA's Teaching From Space Program,
which gives schoolchildren the chance to ask questions and hear
answers from astronauts living aboard the space station via Amateur
Radio on the International Space Station (ARISS). The contact is
performed using the Amateur Radio telebridge network, a world-wide
network of amateur radio ground stations that allow students to
contact the space station, as it flies more than 200 miles above
Earth.
Leyada students came prepared with a list of 20 questions for Had-
field, from everything about what life in space is like to homesick-
ness and boredom. One of the ninth grade students, Ron, asked Had-
field where he slept more comfortably - on Earth or in the space
station. Hadfield laughed, replying that "sleeping in the space sta-
tion is comfortable, but I sleep better at home with my wife." An-
other student, Yoni wanted to know how astronauts distinguish between
day and night in the space station. Hadfield explained that there
were 16 sunrises a day, but the crew uses an alarm clock for their
sleep routines.
Along with the physics team, over 200 Leyada students listened care-
fully to the audio conversation which took place at 11 am in the
morning.
Although the weak signals cut the fascinating conversation short,
for Ya'arit Segal, one of the student leaders of the project, the
prize was worth the hours that she and her team spent on the project
for the past three months. The ninth grader described many sleepless
nights that she her teammates experienced creating their successful
space project. "We spent days and nights working on our project and
the process had a huge impact on us," she told Tazpit News Agency.
"I don't know if I'll be an astronaut someday," concedes Segal. "But
it would be so interesting to conduct experiments in space and learn
how to work together with a crew." Leyada's principal, Dr. Gilead
Amir, was especially impressed with the students' initiative. "Today
was a great example for all of us, both students and teachers - in
learning how school projects can directly impact our lives. Some-
times what we do at school can even lead to historical moments."

Changes Announced at Space-Track Website to Access Tracking Data
This week the Space-Track website published the following memo to
the satellite community who use their site to access the latest
Keplerian Elements for tracking:
-----
We are pleased to announce that we will upgrade the current
http://www.Space-Track.org on Wednesday, 20 February 2013 at 12:00
PST to add the look and functionality that matches what is now on
https://beta.space-track.org. The bulk file downloads from our
current Space-Track site will continue to be available to scripters
for a limited time after the upgrade using established URLs.
This upgrade will vastly improve how the Space-Track User community
interacts with orbital element sets, the satellite catalog and con-
junction data. With a robust Representational State Transfer (REST-
ful) Application Programming Interface (API), scripters will be able
to get the latest data available, customized for their purposes.
Here are just a few of the new features that will become part of the
upgraded www.Space-Track.org:
+ A streamlined and intuitive user interface that is easier to
navigate and allows simple searches.
+ A robust help and documentation section - "Favorites" lists to
identify logical groupings of catalog objects that Users can
monitor via the web interface or with the site's API.
If you have production scripts that currently use
beta.space-track.org, we recommend that you change your scripts to
point at www.Space-Track.org on or after 20 February 2013.
If you have scripts that screen-scrape or download text/zip files
from the current yellow-colored legacy www.Space-Track.org, they
will continue to perform correctly for a few months, but we recom-
mend that you quickly transition your scripts to take advantage of
the new API. Documentation is available under "Help" to assist you,
as well as the API query builder tool on the upgraded site.
We have also started sharing information about Space-Track's new
features on tumblr, facebook and twitter, so please engage us on
your favorite social media platform.
Our sites are http://space-track.tumblr.com,
http://www.facebook.com/SpaceTrack, and
http://www.twitter.com/SpaceTrackOrg
We understand that any significant upgrade has the potential to
cause frustration for our user community and we apologize if this
creates any adjustment problems for you. For help or clarification,
please email us at admin@space-track.org.
Thank you,
The www.Space-Track.org Team
