AO-85 Update: Do Not Access While in
Eclipse The auto Safe mode was disabled on June 24 and the transponder was turned on. A few
QSOs were made to verify that it would drop with inactivity. Currently, the battery voltage is very low and it looks like a cell is prepared to
give up the ghost. Please do not use the
satellite while it is in eclipse, even if
you hear it. Operations is not sure what will be usable if and when this cell
fails ...

Do NOT attempt to work ‘85 when it is in eclipse - even if you do hear it. (From AMSAT last week.)

NASA to Broadcast Next Space Station Resupply Launch, Prelaunch Activities

NASA to Broadcast Next Space Station Resupply Launch, Prelaunch Activities
 

A SpaceX Falcon 9 rocket and Dragon cargo craft launches from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida at 2:48 a.m. EDT May 4, 2019 on the company's 17th Commercial Resupply Services mission for NASA to the International Space Station.

NASA commercial cargo provider SpaceX is targeting 7:35 p.m. EDT Sunday, July 21, for the launch of its 18th agency-contracted resupply mission to the International Space Station. Live coverage will begin on NASA Television and the agency’s website Sunday with prelaunch events.

 

 

The Dragon spacecraft will deliver supplies and critical materials to directly support dozens of the more than 250 science and research investigations that will occur during Expeditions 60 and beyond. In addition to bringing research to station, the Dragon’s unpressurized trunk is carrying the International Docking Adapter-3 (IDA-3), which, when installed on the space station, will provide the microgravity laboratory with two common ports enabling expanded opportunities for visiting vehicles, including new spacecraft designed to carry humans for NASA’s Commercial Crew Program.

 

Dragon will dock to the space station Tuesday, July 23. When it arrives, NASA astronaut Nick Hague will grapple Dragon with NASA astronaut Christina Koch acting as a backup. NASA’s Andrew Morgan will assist the duo by monitoring telemetry during Dragon’s approach. The station crew will monitor Dragon vehicle functions during rendezvous. After Dragon capture, mission control in Houston will send ground commands for the station’s arm to rotate and install it on the bottom of the station’s Harmony module.

 

Full mission coverage is as follows (all times Eastern):

 

Sunday, July 21

 

  • 9 a.m. – Prelaunch news conference from NASA’s Kennedy Space Center in Florida with representatives from the agency’s International Space Station Program, SpaceX and the U.S. Air Force’s 45th Space Wing.
  • 12 p.m. – NASA Social What’s on Board science briefing from Kennedy. This briefing will highlight the following research:
    • Pete Hasbrook, office manager for NASA’s International Space Station Program Science Office, will share an overview of the research being conducted aboard the space station and how it benefits exploration and humanity.
    • Ken Shields, chief operating officer for the International Space Station U.S. National Laboratory, will discuss the lab’s work in advancing science in space, and in developing partnerships that drive industrialization through microgravity research.
    • Gene Boland, chief scientist at Techshot, Inc., and Ken Church, chief executive officer at nScrypt, will discuss the BioFabrication Facility, which is designed to print organ-like tissues in microgravity, acting as a stepping- stone in a long-term plan to manufacture whole human organs in space using refined biological 3D printing techniques.
    • George Papakonstantopoulos, principal scientist at Goodyear Tire, will discuss pushing the limits of silica fillers for tire applications. A better understanding of silica morphology and the relationship between silica structure and its properties could improve the silica design process, silica rubber formulation, and tire manufacturing and performance on the ground.
    • Valentina Fossati  from the New York Stem Foundation Research Institute and Andres Bratt-Leal from Aspen Neuroscience, will discuss the Space Tango – Induced Stem Cells investigation, where cells from patients with Parkinson’s disease and Multiple Sclerosis will be cultured on the space station to examine cell to cell interactions that occur in neurodegenerative disease.
    • Rasha Hammamieh, principal investigator from the United States Army and Melissa Kacena, co-investigator at Indiana University School of Medicine, will discuss the Cell Science-02 investigation comparing the ability of two different bone inducing growth factors, one novel and one currently used in bone healing therapies, to stimulate growth, differentiation and related cellular functions of osteoblast in the microgravity environment.  
    • Jason August, manager of the International Space Station  Mission Evaluation Room, will discuss the International Docking Adapter-3 (IDA-3), where Boeing's CST-100 Starliner and SpaceX's Crew Dragon spacecraft will dock in the near future when bringing astronauts to the station as part of NASA's Commercial Crew Program.
  • 7 p.m. – NASA TV launch coverage begins for the 7:35 p.m. launch

 

Tuesday, July 23

 

  • 5:30 a.m. – Dragon rendezvous, grapple and berthing. Capture is scheduled for approximately 7 a.m.
  • 8:30 a.m. – Dragon installation to the nadir port of the Harmony module of the station

 

Dragon will remain at the space station until Aug. 20, when the spacecraft will return to Earth with research and return cargo.

 

The deadline for media to apply for accreditation for this launch has passed, but more information about media accreditation is available by emailing ksc-media-accreditat@....

I saw that the DK3WN sat database is showing AO-85 as inactive.  Is this the last word?

Clint,
What may be a good indication that the AO-85 is in the eclipse?

It is the phase in which the satellite doesn't receive the sunlight to recharge itself through the solar cells that in turn reduces the power of the satellite to transmit/receive signals from the earth station.

Is that helpful?

Hi Clint,
I figured that is what was happening during the eclipse.
Thanks.

ARISS-SSTV Project

Monday, July 22, 2019
Two SSTV events during July 29 - August 4.
 
Below is the scheduled (as of July 22) for the planned activation of SSTV from the ISS. The first session is the routine MAI-75 activity that is only active for a few orbits. It appears that the most of the world (except N. America) will get a shot during the two day run. Some lucky operators along the east coast of North America should get a pass on July 29.


Inter-MAI-75 activity
(July 29) GMT 210/13:15  – SSTV activate
(July 29) GMT 210/21:25  – SSTV power down
 
(July 30) GMT 211/13:50 – SSTV power up
(July 30) GMT 211/19:30 – SSTV shutdown
 
The second event will be a world wide event running from August 1 through August 4 and will be a memorial event to honor Owen Garriott - W5LFL. He was the first person to operate amateur radio from space. We owe much to his efforts to bring the hobby to space for other operators. The schedule is below  (as of July 22)


 
ARISS Garriott memorial SSTV activity
(Aug 01) GMT 213/09:40  – SSTV activate
(Aug 02) GMT 214/14:00 – SSTV check 
(Aug 04) GMT 216/18:15 – SSTV shutdown

If you have never worked SSTV from the ISS, it is incredibly easy - as simple as holding up your Smartphone up to your HT’s speaker!
