January 30 Announcement Date for NASA ELaNa CubeSat Launch Initiative
AMSAT-NA is waiting to hear whether our proposal to include the
Fox-1 cubesat in NASA's "Educational Launch of NanoSat" (ELaNa)
program has been accepted. NASA selects projects that they deem
to have merit in support of their strategic and educational goals.
Projects that are selected will be able to enter into a collabora-
tion agreement where NASA will cover the integration and launch
costs of the satellite.
AMSAT, working with ARRL, highlighted the educational merit of the
project including the incorporation of Fox-1 into the ARRL Teacher
Institute seminars. ARRL also provided a letter of support for the
project that was a key component of our proposal.
The Clay Center for Science and Technology at the Dexter and South-
field schools in Brookline, MA, also provided a letter of support
that was an important part of our proposal. The Clay Center noted
that they use AMSAT satellites such as ARISSat-1 in their educa-
tional activities for K-12 students and that they look forward to
making use of Fox-1.
The completed proposal, at 159 total pages, required a significant
effort that was all done by volunteers. NASA will select from all
of the submissions and announce the winning projects by January 30,

The ARRL has posted a new, highly informative article on how the
world's first Amateur Radio satellite, OSCAR-1, came to be designed,
built and launched.
The ARRL's Space Communication web page has an English translation
of, "OSCAR-1 Launched 50 Years Ago", written by Andreas Bilsing,
DL2LUX. This article was first published in the German magazine Funk-
amateur. It is reprinted with their permission. OSCAR-1 was launched
just over 50 years ago, on December 12, 1961.
Andreas lives in Leipzig, Germany. He is a member of AMSAT-DL and
has written articles in the AMSAT-DL Journal and Funkamateur. He also
wrote the first German Summits on the Air (SOTA) manual. His other
interests include home brewing, qrp, digimodes and satellites.
Licensed since 1975 at age 16 he has held prior calls of DM4MTG,
DM2FAG, Y26AG, and Y23AM. He holds degrees in energy process engin-
eering and automation which is applies to his work in an engineering
company as project manager in natural gas, responsible for instrum-
entation of gas plants, pipelines and underground gas storage.
Andreas says the view from his shack includes Leipzig's St. Thomas
church where the famous composer J. S. Bach worked.
The AMSAT 2011 Space Symposium in San Jose, California featured Lance
Ginner, K6GSJ, one of the OSCAR-1 developers as our banquet speaker.
Lance's talk can be viewed at: http://youtu.be/EWSCCZY1FgQ.

The Chibis-M satellite, RS-39, was deployed from the Progress M-13M
cargo ship into a 500 km orbit on January 24, as planned. RS-39 has
CW beacons on 435.315 and 435.215 MHz.
The RS-39 team requested support from amateur radio operators for
any initial reception reports of Chibis-M as its first orbits were
outside of the range of the satellite's control stations. Reception
reports are being received by e-mail to:
email@example.com. Each report will be confirmed by a
special QSL card.
Shortly after RS-39 was deployed reception reports posted on amsat-bb
said strong signals initially were heard in India (VU3TYG, VU2WMY),
United States (KB1PVH), Australia (VK5DG), Argentina (LU4EOU), and
central Europe (Jakub Hruska).
On later orbits VKFAK reported the telemetry showed a drop in voltage
aboard RS-39 to 2.8 volts in USUN telemetry field. At this time a re-
port from VU2WMY said the CW signal was only heard briefly at AOS.
RS-39 was not heard on a morning pass on January 25 over North Amer-
ca from a report by W1MSG.
Google translation of http://chibis.cosmos.ru/ reports that the con-
trol station switched off RS-39 after initial testing was completed
on the fourth orbit to save battery power. When testing resumes plans
included calibration of the magnetometer, calibration of solar sen-
sors, and testing the three-axis attitude determination algorithm
using the magnetometer and sun sensor. Later postings from the con-
trol station show they are switching RS-39 on and off at various
Mike Rupprecht DK3WN has made available software to decode the RS-39
telemetry. A description of the program is posted by AMSAT-UK at: http://www.uk.amsat.org/4029. This page includes links to download
the software. Mike has created telemetry decoder software for several
satellites. These can be found DK3WN satellite software page: http://tinyurl.com/DK3WN-Sat-Software (in Google English).
Amateur stations tracking RS-39 reported that elements associated
International launch number 11062C, catalog 38051 correlated with
RS-39. Other stations reported success using the tracking elements
for the Progress M-13M cargo ship, however the orbits between RS-39
and Progress were beginning to separate.
VEGA Preparations Proceeding Toward February 9 Launch
Space-Travel.com published an article reporting that final checkout
of Europe's new Vega launcher has been completed marking another
milestone towards its February 9 maiden flight from Europe's Space-
port in Kourou, French Guiana.
All four stages have undergone final acceptance, including the test-
ing of the avionics, guidance, telemetry, propulsion, separation
pyrotechnics and safety systems. These steps culminated on 13 Jan-
uary with Vega's 'synthesis control checks', where all systems were
put into launch mode for the vehicle's final acceptance. This in-
cluded pressurizing the AVUM propulsion systems that actuate the
thruster valves. The rocket's elements were switched on from the
control bench to simulate the launch countdown. The onboard soft-
ware then took over and simulated the different stages of a flight.
The interfaces between the vehicle and the control bench were also
tested. The test review confirmed that everything ran as expected
and that the launcher is ready for flight.
Vega is designed to launch payload masses ranging from 300 kg to
2500 kg, depending on the type and altitude of the orbit required
by the customers. The benchmark is for 1500 kg into a 700 km
altitude polar orbit.

Opportunity for Citizen Scientists: Globe At Night Project
The GLOBE at Night program is an international campaign to raise
public awareness of the impact of light pollution by inviting citi-
zen scientists to measure their night sky brightness and to submit
their observations to a website from a computer or smart phone.
The GLOBE at Night campaign has run for two weeks each winter/spring
for the last six years. People in 115 countries have contributed 66,000
measurements, making GLOBE at Night one of the most successful light
pollution awareness campaigns.
In 2012 there remain three opportunities to participate in GLOBE at
Night: February 12-21, March 13-22, April 11-20.
This project consists of five Easy Star-Hunting Steps:
1) Find your latitude and longitude.
2) Find Orion, Leo or Crux by going outside more than an hour
after sunset (about 8-10pm local time).
3) Match your nighttime sky to one of our magnitude charts.
4) Report your observation.
5) Compare your observation to thousands around the world.
Teacher Activity Packets and Family Activity Packets are available
from the website.

The Southern Africa SA AMSAT web page (http://www.amsatsa.org.za/)
lists the current status of SumbandilaSat SO67 as, "No service all
activities suspended; Beacon is not operational."
AMSAT-UK has published the news from South African Defence Web pages
(http://www.defenceweb.co.za) in an article titled, "SumbandilaSat
beyond repair", South Africa's second satellite, SumbandilaSat, is
no longer fulfilling its main purpose due to technical problems and
is essentially beyond repair, its maker SunSpace says.
SunSpace, told defenceWeb that although contact can still be made
with the satellite, it cannot capture images and is thus "not ful-
filling its main purpose".
He said that chances of repairing the satellite are virtually zero
and that SunSpace has moved on to other projects.
SumbandilaSat was damaged during a solar storm in the June last
year. The power supply to SumbandilaSat's onboard computer stopped
working and the satellite stopped sending back images.
According to DefenceWeb, South Africa's Department of Science and
Technology (DST) is planning to launch a constellation of satellites
similar to SumbandilaSat in the next 10 to 15 years. One of these
will be SumbandilaSat 2, which will be larger and more reliable than
its predecessor. Funding for SumbandilaSat 2 will be sought during
the next financial year, starting April 1. Development will take
about four years. The image processing methods and mission control
systems pioneered on SumbandilaSat will be used on future satellites.
