EO-88 (Nayif-1) Reenters

EO-88, with its 70cm to 2m linear transponder, having spent a trouble free
6 years and 5 months in space, finally re-entered the Earth’s atmosphere
and burned up on Tuesday, 18th July. Having originally been launched into a
500km orbit, EO-88 has reduced in altitude rapidly over the past year due
to the increased level of solar activity.

Remarkably, some of the last frames of telemetry were captured as the 1U
CubeSat passed over the South Western United States. The final 90 seconds
show a rapid rise in temperature across all the satellites sub systems. The
last frame of data was captured by David WB0IZO in New Mexico at 18:18:54
UTC showing the antenna temperatures operating about 40 degrees above
normal.

During the past 2 weeks, 86 stations have contributed EO-88 telemetry to
the FUNcube Data Warehouse and this has given us the opportunity to study
the behaviour of a functioning CubeSat as it makes its return from Space.
Thank you all for your support.

Having provided the last frame of data, David WB0IZO, wins the telemetry
section of the AMSAT-UK re-entry competition and will receive a framed
certificate of achievement.

The prediction for the date and time of re-entry was very close with Paul
N8HM predicting the 17th July and Larry N1MIW calculating the 21st.
However, the winning entry was made by Thomas HB9SKA who correctly
predicted the 18th July. Thomas also wins a framed certificate.

RIP EO-88. GOODBYE AND THANKS FOR THE FUN!

URESAT-1 Update

This is an update about our satellite URESAT-1, launched with SpaceX on
June 12th (Transporter-8 mission from Vanderberg) and using Alba Orbital as
our space broker. First of all, URESAT-1 is a small pocketQube 1.5P (8x5x5
cm), much smaller than a Cubesat.

The satellite was expelled from the D-Orbit Orbital Transfer Vehicle (OTV)
ION ten days after the launch, on June 22th at 12.10 UTC, along with
MRC-100 and ROM-2 satellites. Soon after, using the OTV TLE available for
pointing, signals from MRC-100 and ROM-2 were received but not ours... This
made us think we again had a problem with the deployment of the antennas.

Fortunately Daniel EA4GPZ could receive the URESAT-1 on June 26th using the
ATA radio telescope at 22.03 UTC. The pattern of the transmissions matched
and, using the IQs from the two antennas used, with two polarities, we
could decodify telemetry, showing that the satellite was performing well
with no resets or events. The battery was almost fully charged but the
antennas were not deployed, as it was shown in the status packet received.
We worked hard to improve the deployment system from our previous
satellites but something hasn't gone well again. Satellite seems to be cold
even in sunlight but we performed tests using temperatures as low as 20 C
below zero so this should not be a problem...

Doing a lot of analysis (after the ATA observation we found that our
satellite was 20-30 seconds ahead of MRC-100)  and with a lot of help from
the Satnogs thread regarding that launch, we managed to conclude that our
satellite should be NORAD object 56992.

The team at Dwingeloo radio telescope on Netherlands has confirmed this
with several observations these days

https://network.satnogs.org/observations/7877553/
https://network.satnogs.org/observations/7881183/
https://network.satnogs.org/observations/7883687/

Using the IQs of these recordings (available here
https://data.camras.nl/satnogs/) we have been able to decode new telemetry,
CW and even a SSTV image from the satellite image bank. After more than
three weeks in orbit the satellite is performing well and we hope that the
antennas will deploy at some moment.

The plan now is sending the satellite commands to try to deploy the
antennas, although we are going to need a lot of power because the received
signal without a proper antenna will be low. If you have a powerful station
for transmitting on VHF and want to help us, please let me know.

We want to thank Daniel EA4GPZ, the ATA radio telescope, PE0SAT, the
Dwingeloo staff, especially Tammo Jan, and Satnogs staff for their kind
help in identifying the URESAT and the reception of their signals. It has
provided very valuable data on the status of the satellite.

Decoded telemetry, CW and the SSTV image is available in our web (sorry, it
is in spanish) and also in the Satnogs thread about the Transporter-8
mission:

Special ARISS SSTV Experiment Scheduled for ARRL Teacher's Institute

Amateur Radio on the International Space Station (ARISS) in collaboration
with the American Radio Relay League (ARRL), plan to carry out a special
Slow Scan TV (SSTV) experiment from the ISS on Wednesday, July 26, 2023.
During the event, the Columbus Module Repeater, transmitting at 437.800
MHz, will carry a message to be received by teachers attending the ARRL
Teacher’s Institute class. The pass will be over the Mid-Atlantic / New
England area with transmissions scheduled to begin at 20:05 UTC (16:05 ET)
and ending at 20:20 UTC (16:20 ET). If necessary, a backup window will be
21:40 UTC (17:40 ET) to 21:55 UTC (17:55 ET).

Radio enthusiasts are welcome to download the message and follow along with
the event, but we ask that all hams please refrain from using the repeater
for voice contacts during the event.

Please understand this is a special experiment conducted through ARISS and
the ARRL. All regular operation of the repeater should continue to take
place in voice mode only.

Check ARISS Social Media for any updates.

Changes to AMSAT-NA TLE Distribution for July 20, 2023

Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
https://www.amsat.org/keplerian-elements-resources/

The following satellites have been added to this week's AMSAT-NA TLE
distribution:

CUbeBel 2 (EU11S) NORAD Cat ID 57175 IARU Coordinated Frequency: 436.99 MHz.
(Thanks to Nico Janssen, PA0DLO for identification)

URESAT-1 NORAD Cat ID 56992 IARU Coodinated Frequency: 436.888 MHz
(Thanks to Felix Paez, EA4GQS AMSAT EA President for identification)

The follwing satellite has decayed from orbit and has been removed from
this week's AMSAT-NA TLE distribution:

EO-88 (Nayif 1)  NORAD Cat ID 42017 "[R]e entered over North America.
The last frame of data was provided by WB0IZO in NM" according to David
Bowman G0MRF AMSAT-UK

ARISS News

Amateurs and others around the world may listen in on contacts between
amateurs operating in schools and allowing students to interact with
astronauts and cosmonauts aboard the International Space Station. The
downlink frequency on which to listen is 145.800 MHz worldwide.

Quick list of scheduled contacts and events:

Mohammad Bin Rashid Space Centre, Dubai, UAE, direct via A68MBR

The ISS callsign is presently scheduled to be OR4ISS
The downlink frequency is presently scheduled to be 145.800 MHz
The scheduled crewmember is Sultan Al Neyadi KI5VTV
The ARISS mentor is ON6TI

Contact is go for: Thu 2023-07-27 09:57:42 UTC 88 deg

The crossband repeater continues to be active.  If any crewmember is so
inclined, all they have to do is pick up the microphone, raise the volume
up, and talk on the crossband repeater.  So give a listen, you just never
know.

Comments on making general contacts

I have been seeing a lot of traffic on Facebook and I suspect on other
social media sites with people asking why they are not hearing the crew
make general contacts.  First off the crew is very busy on the ISS and they
simply may not have the time to just pick up the microphone and talk.
Also, one needs to be aware of their normal daily schedule.  I have listed
below the constraints that we at ARISS have to follow in order to schedule
the school contacts.  Hopefully this will help you better schedule your
opportunities.

Typical daily schedule

Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours

The crew's usual waking period is 0730 - 1930 UTC. The most common times to
find a crew member making casual periods are about one hour after waking
and before sleeping, when they have personal time. They're usually free
most of the weekend, as well.

SSTV events are not that often.  So please check out https://www.ariss.org/
for the latest information or watch for the ARISS announcements.

And don’t forget that the packet system is active.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.

ARISS Radio Status

Upcoming Satellite Operations

>From David, N9KT:
I’ll be at the Philmont Scout Ranch activating DM76 on all the satellites
from July 19-28 using voice and digital. I’ll be doing demonstrations and
training for Radio Merit Badge and hope to be very active on the birds
every day. (Ed: David doesn’t appear to be active on Twitter. I’ve
suggested hams.at as an outlet for more detailed info as the date(s) draw
closer.)
I’ll also be trying to activate some grids on the trip out (July 17-18) and
back (July 29-30) between Indianapolis and the Philmont Scout Ranch.

BI1NJI will be QRV as BI1NJI/3 from ON83 24th through 27th July. FM and
IO-117. This is all I know at the moment. He does do Twitter (@YankaiP) and
has said that details will follow.

Satellite Shorts From All Over

+ From Bruce Paige, KK5DO, (kk5do at arrl.net) "July 25 at 11:59pm is the
deadline to get your summary sheets to be scored for this years AMSAT Field
Day. I have received very few scores and even fewer pictures this year.
Even if you have already submitted your entry, drop me a picture or two
with a description."

+ Philippine cubesats May-5 and Maya-6 have been deployed. The satellites
were launched to the International Space Station on June 5 aboard the
Japanese Experiment Module (JEM) Small Satellite Orbital Deployer-26, and
were released from the ISS on July 19. The primary mission of Maya-5 and
Maya-6 CubeSats is to provide digital message relay service to the amateur
radio community by means of an APRS (Automatic Packet Reporting System)
digipeater onboard. The APRS digipeater onboard the CubeSats will use
145.825 MHz for both receive and transmit. Another mission of the cubesats
is to demonstrate a data/message store-and-forward (S&F) system in line
with the Universal Amateur Radio Text and E-mail messaging. The CubeSats
will also carry Commercial off-the-shelf (COTS) cameras which will take
images of the participating countries from space for promotional and
educational awareness. A downlink on 437.375 MHz and APRS activities on
145.825 MHz have been coordinated. (ANS thanks The Philippine Daily
Inquirer and IARU for the above information)

+ The Order of Malta's Italian Relief Corps (CISOM) Amateur Radio Station -
1A0C will be activated from July 26th to August 2nd at the Magistral Villa
on the Aventine (Rome). The Sovereign Military Order of Malta is a separate
DXCC entity. Satellite operations are expected on LEO satellites and
QO-100. Details to follow (ANS thanks the 1A0C team for the above
information)

+ The Sun's activity is defying forecasts and highlighting how difficult it
is to predict the machinations of Earth's nearest star. Space weather can
shorten the lifespans of satellites, cause radio blackouts and, in extreme
solar storms, bring down power grids. Predictions from 2020 suggested the
Sun would reach the peak of its 11-year solar cycle in 2025, and its
intensity would be on par with the last cycle. But current observations
show its activity could now peak as early as 2024. The current cycle is
also on track to be more extreme, with more solar flares, sunspots and
activity than the previous one, though not as big as others on record. The
National Oceanic and Atmospheric Administration is planning to fly two new
instruments to space that should help them keep an eye on the Sun in the
coming years. A Sun-focused instrument is slated to launch on the GOES-U
weather satellite next year, and another instrument will fly in 2025. (ANS
thanks Axios Space for the above information)

+ Congratulations to Joel Weiner, VE6WQ, the 60th recipient of the AMSAT
GridMaster Award.
The AMSAT GridMaster is awarded to those operators who confirm QSOs with
all 488 maidenhead grid squares located within the continental United
States. https://www.amsat.org/gridmaster/ (ANS thanks Bruce Paige, KK5DO,
