Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Power generation by the solar arrays is described in this paper.
Ancillary sc data are provided here. The latest currently available data set is of Sol 569. Data are only partially recorded. Here an attempt to plot a diagram: The maximum current within the data set is roughly 0.1 A. The portion I don't yet understand is the factor of 11,000 Vh in Figure 4 of the above paper. If we would just use that factor, we would get about 1 kWh for Sol 569. But the factor may depend on the duration of the daily sunshine. Unfortunately, I don't have access to more recent telemetry. More information about InSight power management is provided in this paper. The power requirement of SEIS is described in this paper. The heaters seem to consume up to 1.5 W. The instrument usually requires about 5.9 W, see subsection 4.1.9, but can be up to 11.83 W, see Table 5. So, 250 Wh per day should be sufficient to operate SEIS continuously. In addition, the main system, and communication requires power. I didn't yet find out how much. And there will be some power loss by the batteries. HP3 is described in this paper. See Table 1 for information about a 4h hammering activity. If I summed up correctly, it's 367 Wh. Thus far my attempt of today to provide some, but a still incomplete, basis for further considerations. |

Thus far my attempt of today to provide some, but a still incomplete, basis for further considerations. I think we can be confident that the team has thought about additional activities that could be tried to recover some of the HP3 science, and they are in a much better position than we are to evaluate what's possible and what's not. -------------------- Disclaimer: This post is based on public information only.
