OSCAR Numbers Assigned for BRICsat (NO-83) and PSAT (NO-84)
The following message has been sent to Bob Bruninga, WB4APR and the team
at the
US Naval Academy.
"Bob:
You have requested OSCAR numbers for BRICsat and PSAT built by you and your
associates at the U.S. Naval Academy.
From everything I can determine, these satellites meet all of the
requirements
for OSCAR designations.
Therefore, by the authority vested in me by the AMSAT-NA President, I hereby
confer the designation, Naval Academy OSCAR 83 on BRICsat amd Naval Academy
OSCAR 84 on PSAT These designations can, of course, for convenience, be
shortened to NO-83 and NO-84.
I, and the entire amateur satellite community, hope for successful missions
for both NO-83 and NO-84 and congratulate you and the rest of the Naval
Academy
team who designed, built and tested these two OSCAR spacecraft.
73,
William A. (Bill) Tynan, W3XO
OSCAR Number Administrator"
NO-84 PSAT, a student satellite project named in honor of USNA alum
Bradford Parkinson, of GPS fame, contains an APRS transponder for relaying
remote telemetry, sensor, and user data from remote users and Amateur Radio
environmental experiments or other data sources back to Amateur Radio
experimenters via a global network of Internet-linked ground stations.
PSAT is another APRS satelliite that can digipeat user packets just like the
original PCSAT (NO44) and the packet system on the ISS. PSAT also
supports the
same digipeating alias of ARISS so that users do not have to change any
parameters when using any of these three APRS transponders.

Sailboat Expedition to Grid DM02 Begins June 10
Bud, N7CW; Jim, K6ZH; and Phil, N0KE, plan to activate Grid DM02 from a
sailboat expedition to the waters near San Clemente Island off of the
southern California coast. Departure from San Diego will be on Wednesday,
June 10 aboard a 49' sailboat. The team plans to be on the air sometime late
Wednesday, through sometime on Sunday, June 14, including most of the VHF
contest. Unfortunately, they have to leave before the end of the contest
because the Navy has scheduled exercises in the area on Monday.
Activity includes 6 M, 2 M, probably 432, 1296 and satellites. Phil is
responsible for everything other than 6 M. They plan to look for meteor
scatter every morning and perhaps the evenings, unless there is Es. Since
there is no cell service they will be in contact with pilot stations on 2 M
FM in order to announce ourselves on Ping Jockey. If you don't use meteor
scatter, it's not too late to learn! Otherwise you will have to listen for a
very short (distance) Es opening or backscatter or some other nearly
impossible propagation mode.
The expedition will be running about 500 W and a 3 el yagi (due to
constraints from having to mount the antenna on a sailboat). They will use
the call K6ZH. Watch for packet spots announcing their transmit frequency.

AMSAT Will be at Ham-Com 2015
If you're going to Ham-Com 2015 at the Irving Convention Center in the
Dallas - Ft. Worth area on June 12 to 13 look for AMSAT in booth #103. Also,
check the Ham-Com program for the presentation by Clayton Coleman W5PFG.
Clayton is an active member of AMSAT and the ARRL with a passion for Amateur
Radio in Space. Having activated over 100 grid squares, Clayton enjoys
helping others learn how to use minimal equipment
to enjoy our fleet of OSCAR's.

Satellite Shorts From All Over
* LightSail Drama Continues as Spacecraft Wakes for Second Time
LightSail is back in business, following the second extended outage of the
test spacecraft’s mission. The CubeSat checked in at 2:21 p.m. EDT
(18:21 UTC)
Saturday for the first time since Wednesday afternoon. Over the course
of two
overflights, 23 beacon telemetry packets were received by the
spacecraft's Cal
Poly San Luis Obispo ground station.
A rapid sail deployment was briefly considered, but with battery levels
still
unsteady and just one ground pass remaining before an eight-and-a-half hour
outage, the team scrapped the idea. When LightSail came around the Earth
again,
telemetry showed its batteries were charging—the first time since solar
panel
deployment three days ago.
If battery levels continue to trend stably during Sunday’s early morning
ground station passes, sail deployment will be scheduled for 2:02 p.m. EDT
(18:02 UTC).
Engineers have been working to narrow down the reason LightSail’s batteries
tripped into a safe mode-like condition following solar panel deployment.
Before this afternoon's signal acquisition, the leading theory was that the
spacecraft was stuck in a loop where power levels were too low in Earth's
shadow, but too high in sunlight. This power ping-pong could have
prevented the
batteries from reattaching their circuits to the spacecraft and allowing
normal
operations to resume. The analysis is still ongoing.

* Goddard Technologist Advances CubeSat Concept for Planetary Exploration
Although scientists are increasingly using pint-size satellites
sometimes no
larger than a loaf of bread to gather data from low-Earth orbit, they
have yet
to apply the less-expensive small-satellite technology to observe physical
phenomena far from terra firma.
Jaime Esper, a technologist at NASA's Goddard Space Flight Center in
Greenbelt, Maryland, however, is advancing a CubeSat concept that would give
scientists that capability.
Dubbed the CubeSat Application for Planetary Entry Missions (CAPE), the
concept involves the development of two modules: a service module that would
propel the spacecraft to its celestial target and a separate planetary entry
probe that could survive a rapid dive through the atmosphere of an
extraterrestrial planet, all while reliably transmitting scientific and
engineering data.
Esper and his team are planning to test the stability of a prototype entry
vehicle -the Micro-Reentry Capsule (MIRCA) - this summer during a
high-altitude
balloon mission from Fort Sumner, New Mexico.
'Like No Other CubeSat Mission'
"The CAPE/MIRCA concept is like no other CubeSat mission," Esper said. "It
goes the extra step in delivering a complete spacecraft for carrying out
scientific investigations. We are the only researchers working on a concept
like this."
Under his concept, the CAPE/MIRCA spacecraft, including the service
module and
entry probe, would weigh less than 11 pounds (4.9 kilograms) and measure no
more than 4 inches (10.1 centimeters) on a side. After being ejected from a
canister housed by its mother ship, the tiny spacecraft would unfurl its
miniaturized solar panels or operate on internal battery power to begin its
journey to another planetary body.
Once it reached its destination, the sensor-loaded entry vehicle would
separate from its service module and begin its descent through the target's
atmosphere. It would communicate atmospheric pressure, temperature, and
composition data to the mother ship, which then would transmit the
information
back to Earth.
The beauty of CubeSats is their versatility. Because they are relatively
inexpensive to build and deploy, scientists could conceivably launch
multiple
spacecraft for multi-point sampling - a capability currently not
available with
single planetary probes that are the NASA norm today.
Esper would equip the MIRCA craft with accelerometers, gyros, thermal and
pressure sensors, and radiometers, which measure specific gases; however,
scientists could tailor the instrument package depending on the targets,
Esper
said.
A Balloon Flight is designed to test stability.
The first step in realizing the concept is demonstrating a prototype of the
MIRCA design during a balloon mission this summer. According to the
plan, the
capsule, manufactured at NASA's Wallops Flight Facility on Virginia's
Eastern
Shore, would be dropped from the balloon gondola at an altitude of about
18.6
miles (30 kilometers) to test the design's aerodynamic stability and
operational concept. During its free fall, MIRCA is expected to reach
speeds of
up to Mach 1, roughly the speed of sound.
"If I can demonstrate the entry vehicle, I then could attract potential
partners to provide the rest of the vehicle," Esper said, referring to the
service module, including propulsion and attitude-control subsystems. He
added
that the concept might be particularly attractive to universities and
researchers with limited resources.
In addition to the balloon flight, Esper said he would like to drop the
entry
vehicle from the International Space Station perhaps as early as 2016 -
a test
that would expose the capsule to spaceflight and reentry heating
conditions and
further advance its technology-readiness level.
"The balloon drop of MIRCA will in itself mark the first time a CubeSat
planetary entry capsule is flight tested, not only at Goddard, but anywhere
else in the world," he said. "That in turn enables new opportunities in
planetary exploration not available to date, and represents a game-changing
opportunity for Goddard."
