Log Book for April 7, 2003
Commander's Check-In
Bill Clancey Reporting
Time: 18:30
Weather: low 22.1F (-5.5C); high 65.8F (18.8C)
Crew Physical Status: Slightly sore from our hikes on the off-day, but ready for another week.
Brief Narrative of Field Mission Results: We had a good half-hour briefing shortly after 9am, reviewing our written problem report and resolution plan (which the commander now maintains). We met again at 11am for an hour as a subgroup to review the analysis results, and prepared a revised test protocol, involving placing GPS units outside, and attaching them to the suit after the geologist-astronauts step outside onto the hab's "porch."
At 2pm, after lunch we tested scenario 1B, which (once again) involved putting on the helmets with the backpacks and walking on a predetermined route around the hab. The test took over 2 hours, showing that some problems were resolved and others were not. Basically, we're now concerned with second order functionality: The Mobile Agents system FTP's multiple images from the camera to the HabCom; the astronauts can make multiple voice notes and play them back (and these too are FTP'd to the HabCom); multiple sample bags are logged. However, the operation to associate data with locations or voice notes with bags is not working, and science data is not being emailed out, By setting the polling rate at an absurdly large 10 minute interval today, we determined that processing of biosensor and GPS data is not slowing down the system.
John Dowding greatly improved the reliability of voice commanding by implementing an explicit confirmation dialog, so each command is confirmed by the astronaut before it is executed. This appeared to work well. However, naming locations is not working because establishing a location ("Where am I?") is not working.
For unknown reasons, one astronaut's GPS data was not being received and the other astronaut's biosensor data logging wasn't properly initialized.
ERA tests showed that commands were received and executed, but response to acknowledge completiion not received.
Nathan Howard spent 11 hours driving to SLC and back to get a part machined for the ERA; so it will be moving again tomorrow.
Successes for the day include: Repeated the basic 1B "walk around the hab" scenario, showing basic science logging functionality is now working. Feedback to astronauts was better (e.g., commands are confirmed).
We met for an hour about 17:10, for an exhaustive review of all functionalities and pending changes.
Plans for Tomorrow: We made some important strategic decisions: We will move to Scenario #2 tomorrow, a walk down a nearby ravine. The morning will again be devoted to debugging and system improvements, focusing on email, data associations, naming locations, and ERA "callback." We will aim for a 2pm suited test, which is only loosely scripted with five waypoints, including three work locations. We will treat the test like a "mission," which will include lower priority subtests. In particular, biosensors will not be tracked until the astronauts are working at the most distant point. GPS tracking will start at five minutes and be reduced to 1 minute for the walk back. The ERA will be tested after basic functionality has been tested during the EVA. If all goes well, we'll include more tests during the EVA
Report Transmission Schedule: We will select, prepare, and transmit today's photos either later tonight or early tomorrow morning, or Monday morning.
Maintenance: Thanks to Don Foutz's effort on a Sunday morning, the belt of the Generac is temporarily replaced. Frank is working on solving a battery charging problem with the blue truck. All other systems operational.
EVA Narrative/Data/Interpretations: Yesterday we hiked in Bell and LIttle Horse Canyons near Goblin Valley. This was a great 13km adventure through slot canyons and washes, lasting about 5 hours. With intermittent snow flurries, the dew point was 19F. We had dinner at the "fine dining" restaurant in Hanksville, which is not heated.
Inventory: We stopped measuring the bread mix so precisely (with our new measuring spoons), and produced much better bread. Arguably, this is also our computer debugging style.
Miscellaneous: The speech system confirmed a command by pronouncing "camera" as came-R-A. People will always enjoy laughing at such mistakes, and we can look forward to decades of making fun of our robots.
