Orbital debris has long been of concern and several methods of dealing
with it have been proposed in recent years.
Larger objects can, for the most part, be avoided as they are tracked.
Some of them are spacecraft that reached the end of their operational
lives and could still be useful if they could be refurbished. That
could be a possible source of revenue for a salvage firm, provided
that those inactive spacecraft could be made safe prior to being
brought back. (One space shuttle mission showed this was possible.)
Others could be removed from orbit if they were put into, say, a
trajectory which would eventually cause them to re-enter and burn up.
Tasks like that could be something that a successor to the ATV might
be suited for. Perhaps such a spacecraft could be developed by a
private company with backing from a government space agency.
Smaller pieces, such as paint chips, won't be so easy to remove. I
remember reading of one proposal that deployed a fine-mesh net which
would catch them. Maybe an ATV successor might not be the best
spacecraft for that as precise maneuvering probably wouldn't be
required.

Video Posted From ARISS Contact with 8N3KN in Japan
On Wednesday, June 6, students attending Kawachinagano Eastside
Junior High school, Osaka prefecture, Japantook part in an Ama-
teur Radio on the International Space Station (ARISS) contact
with Andr? Kuipers, PI9ISS on ISS.
At the beginning of the contact the school was experiencing a power
blackout, but recovered in time so that all children were able to
ask their questions. The event supplemented lessons about space and
the ISS.
Video of this contact is now available on YouTube:

Celebrating 10th Anniversary of OSCAR 7's Return To Life
An article posted on the AMSAT-UK web this week reminds us of the
10th anniversary of the auspicious discovery by Pat Gowen, G3IOR
on June 21, 2002 when he first noticed a beacon sending slow 8-10
wpm CW on 145.973.8 MHz. It sounded like old OSCAR satellite tele-
metry, it had the familiar HI HI followed by a string of numbers
in groups of three. After monitoring by many radio amateurs it turn-
ed out to be OSCAR-7, and it seemed to have come back from the dead.
Pat posted a message on the amsat-bb bulletin board, "I have just
come across something most remarkable this Friday 21st June evening
... It sounded VERY familiar ... Could any veteran keen observers
(who might look for it) ..." Pat's original message announcing his
discovery can still be read in the amsat-bb archives, see:
http://www.amsat.org/amsat/archive/amsat-bb/200206/msg00525.html
It is believed that in 1981 the batteries failed short-circuit, how-
ever, in 2002 they became open-circuit enabling the satellite to
run again from the solar panels. Since that day OSCAR 7 has been
operational when in sunlight and provided radio amateurs with many
long distance (DX) SSB/CW contacts.
Remember when working OSCAR 7 use the least uplink power possible
to minimize your downlink power usage, and maximize the number of
simultaneous contacts supported in the passband.

of OSCAR 7 by Dave Rowan G4CUO can be seen at:

AO-7 DX Opportunities
Paul Robinson, 2E1EUB will be operating mobile 2M1EUB as he tours
around Scotland between June 26 through approximately July 9. He
plans operations from grid squares IO77, IO87, and IO86 with addi-
tional coverage if time permits. He will be active from any spots
along the road that he can access the satellites. Activity will be
on 160 and 80 meters, 2 meters SSB and on satellites including AO-7.
Satellite AO-7. Check out QRZ.com under 2M1EUB for more info.
Bill Dzurilla, NZ5N is now active as OM3BD from Slovakia, grid loca-
tor JN88mf this summer and is active on AO-7. Any North American
stations in range are invited to email Bill for skeds:

windows to North America are a bit longer this year, and from my
hill I can hear the bird to -2 degrees."

ARISS Contact Planned as NASA Hosts Future Female Explorers
A press release from NASA Headquarters, Washington, DC notes that
this week eighty-four female high school students from 29 states
will plan a simulated mission to Mars and experience life as an
engineer or scientist when NASA's Johnson Space Center in Houston
hosts two events focused on science, technology, engineering and
mathematics (STEM) in June and July.
The Women in STEM High School Aerospace Scholars project, or WISH,
is sponsoring two six-day summer camps for rising high school sen-
iors. The young women will work in teams with female NASA mentors
to develop mission plans for launching to Mars, living and working
there, and integrating the many components necessary for a successful
planetary mission. They will work within the confines of a fictitious
budget and build several small mockups of vehicles to demonstrate a
successful launch and landing of the Mars spacecraft.
"WISH gives some of our brightest future innovators a chance to ex-
perience some of the exciting challenges that NASA engineers and sci-
entists face on a daily basis," said Johnson Deputy Director and
four-time space shuttle astronaut Ellen Ochoa. "It shows the young
women that there are a variety of opportunities for them in technical
fields."
Young women participating June 24-29 will hear a first-hand account
of life in space from NASA astronaut Shannon Walker. Participants
July 8-13 will have a chance to speak with a current space station
astronaut via ham radio as part of the Amateur Radio on the Interna-
tional Space Station program, a NASA educational initiative that fac-
ilitates direct links between students and astronauts.
The young women were selected based on completion of interactive, on-
line lessons focused on space exploration and mapped to national edu-
cation standards, academic merits and geographic diversity. The WISH
program encourages young women to pursue science, technology, engin-
eering and mathematics degrees and exposes them to the real-world
applications of STEM careers at NASA. This program is in its second
year. It began as a NASA accompaniment to the White House Council on
Women and Girls.

ARISS Status - 18 June 2012
1. Successful ARISS Contacts Held
ESA-ESTEC arranged for an ARISS contact that was
held on Tuesday, June 12 at the
Ruimtevaart Museum in Lelystad, the Netherlands with students that had taken
part in Andr? Kuipers? Mission: Spaceship Earth competition. Through this
program, Kuipers gave assignments to Dutch school children and the winners of
the competition were invited to the event. Kuipers chatted with students and
answered their questions about space. ARISS delegate Bertus H?sken, PE1KEH
attended the event and presented ARISS activities to the audience. Telebridge
station W6SRJ in California handled the radio connection. To view video of the
event, see:

Students from St. Anne?s Primary School in Strathfield South, NSW, Australia
spoke with Joe Acaba, KE5DAR on the ISS through an Amateur Radio on the
International Space Station (ARISS) contact on
Wednesday, June 13 via telebridge
station LU8YY in Argentina. Approximately 150 people attended the event. The
contact was integrated into the space curriculum across all grades and was
held
along with the school?s science fair.
2. Astronaut Training Status
Barry Wilmore took part in an ARISS introductory class on Monday, June 11.
Wilmore is slated to fly with Expedition 41 in September 2014.

By using Kickstarter the ArduSat team have, in just over a week, raised in

aiming for a 2U CubeSat instead of a 1U.
