me know about the change of policy. Please rewrite the contracts with our company, and give us more money and time so that we can add encryption features on the earth stations. As for the mars rovers, since they are already in Mars, we need around a 2 billion dollar to develop a replacement of them so that they can beam back encrypted data. As you know, the original project is about $850 mln, and to reactive the project and sending replacement in short period of time is extremely difficult, we doubled our estimate and hope you approve the new contract. Thank you.
