Between the 27th of April and the 1st of May a Mars analog field test was organized and coordinated by the Austrian Space Forum (OeWF) at the Giant Ice cave at the Dachstein Mountains, Upper Austria, Austria. During this test, the Aouda.X spacesuit simulator and selected geophysical and life-science related experiments were conducted.

The Antipodes experiment was a joint operations simulation between the OeWF (Austria), KiwiSpace (New Zealand) and the Mars Society (USA). 

Antipodes is an operations experiment where a loss of communication (e.g. satellite is out-of-range) to Earth is simulated. A parallel landing party on the other side of Mars is requested to take over the coordination of an ongoing Extra-Vehicular Activity via their habitat, relayed via a satellite in Martian orbit until Earth is able to reestablish contact again.

Four distinct experiments were attempted to establish comms links using the relevant software, simulated rover control from Wellington, OeWF control of an MDRS experiment and MDRS control of an OeWF experiment.

Description of the experiments


Antipodes 0:

Antipodes 0 was conducted on Saturday, 28th of April and was also the first comcheck between the OPS at Dachstein and KiwiSpace. The video and audio worked very well. Due to probably a bandwidth problem the contact was lost during the ends of Antipodes 0.

 

Antipodes 2:

Antipodes 2 was supposed to be conducted on Sunday, 29th of April but did not happen as it was not possible to establish contact between the OPS at Dachstein and KiwiSpace.

 

Antipodes 1:

During this experiment which was operated on Monday, 30th of April MCC Wellington should have directed Aouda.X.

The streamed video had a good quality and a grid that was put over the streamed image was very helpful. Due to a low bandwidth the picture got a little bit blurry when the suit tester and therefore the helmet camera moved fast.

As a result of a communication problem directly before MCC Wellington was supposed to take over it was not clear to MCC Wellington what they were supposed to do exactly during this experiment and therefore it did not go as planned but many new valuable lessons were learned.

 

 

 

Antipodes 3:

This experiment was conducted on Tuesday, 1st of May and had the crew of KiwiSpace at the MDRS directing Aouda.X.

This experiment is considered a big success as everything did go as planned. MCC Wellington had all the information they needed beforehand and the voice communication was very clear. The video stream was fine as well even though it was blurry sometimes.

 

Discussion

 

The communication problems were probably partly due to a low bandwidth and the fact that the OPS and KiwiSpace were communicating via two different servers on Mumble which caused some problems. Unfortunately this was only found out on Tuesday, the last day of the field test, but after the problem was known we were able to establish a solid communication.

Here a valuable lesson learned is that every experiment should be trained some days or even weeks before it´s conducted. So any problems with bandwidth and communication can be detected before and can also be sorted out. With a test run also every participating party knows what to do and questions can be answered before the actual test. Also more than one communication system is needed so that if any problems should arise a quick switch to another system is possible. The hierarchy here should be Video – Audio- Text.

Also some kind of document with the intern structure and persons in command and also with their phone numbers would be very helpful.

 

Another important lesson learned would be that also the onsite crew needs the exact and detailed procedures for an experiment so that it can be conducted even when the communication system has broken down.

Therefore it would also be necessary that more actual scientists are in the field who actually know what they are doing during a science experiment from a scientific point of view.

 

Due to the many lessons learned during the Antipodes experiment but also because of the great and successful collaboration between the OeWF and KiwiSpace we should consider to continue with the Antipodes experiment during our next field missions.

Common Communication Basics

Used Software:

For the communication between the OPS, the suit as well as the field crew in the cave and KiwiSpace in Wellington and Utah the open source voice over IP software Mumble was used (Version: 1.2.2).

Video images of the helmet camera in the Aouda.X spacesuit were streamed via the VLC-Player.

To make all this possible nearly every part of the Giant Ice cave was provided with WLAN for the duration of the field test by OEWF team members.

The radio language for Mumble/Plumble radios is based upon on communication rules commonly used in air traffic and emergency services. 

Call signs:
  • MDRS-Station: MDRS-HABCOM
  • EVA crew member @ MDRS: MDRS-ALPHA (BRAVO, CHARLY,... for additional analog astronauts?)
  • Mission Control Wellington: CAPCOM-WELLINGTON
  • Mission Support Innsbruck: CAPCOM-INNSBRUCK
  • EVA crew member @ Morocco: “X-Ray” for AOUDA.X / “Sierra” for AOUDA.S
  • Operator station at the Morocco field base: BASE
Common phrases used
  • ACK” = acknowledged (pronounced “Aye-See-Kay”)
  • Confirmed” = indicated the called party has understood and agrees
  • Affirmative” = yes: received, understood and agreed
  • Negative” = No
  • Copy” = confirmation, that the message was received and understood, it does not imply, that the receiver agrees to it.
  • Go ahead” = send you transmission
  • ETA” = Estimated Time of Arrival
  • Out” = This is the end of a transmission and no answer is required or expected.
  • Standby” = wait a minute, I am busy but I will come back to you.
Common call signs
  • BASE” = on-site Operations
  • Capcom” = Capsule Communicator in MCC
  • Flight” = Flight director
  • Safety” = Safety officer on-site
  • “BME” = Biomedical Engineer

Emergencies Procedures

EMERGENCIES

Whenever there is an emergency situation (danger of significant damage or loss of life or equipment) in a PolAres setting, the safety officer, the suit tester, or the flight director may declare a “CODE RED”. This is ONLY to be used for real emergencies, NEVER, EVER use it jokingly in everyday language. This code is reserved for real trouble only. (If the team trains on simulated emergencies, the phrase “CODE ORANGE” is being used).

In such a case, any experiment is aborted, the local crew takes over and assess the situation and report as soon as possible back to THEIR MCC or OPS. FLIGHT decides further steps.
