Robustness margins have been increased in thisMission Techniques
If anyone of the issues was not there, the mission would have been a success. We have understood the total data, analysed the data, and understood the problem. Now corrective actions have been taken considering all these issues.You talk about corrective actions; any changes to either the rover or the lander apart from the corrective steps that you mentioned.
Yes. Some improvements were made to overcome the problem. From what we have seen, we have added more redundancy. Suppose one system is failing, the data will be taken from the other system. This redundancy has been increased. The allowable dispersion level is enhanced, the leg design has been modified to withstand higher landing velocity also.
So you are saying if in case the lander lands with a higher speed, it can still withstand the impact.Higher speed, yes, but not like very large speed, like earlier it could withstand up to 2 metres/second ,velocity, now that has been increased to 3 metres/ second. Some extra margins have been built in the allowable limit within the capacity, within the correctable actions. Robustness margins have been increased in this one.We used to get a huge amount of data for a flight and each byte of data was analysed to understand what really went wrong. So, every aspect was looked into very carefully so that no stone is unturned. They recreated the problem at the lab level.
