Huntress, Jr. Associate Administrator for Space Science – Code SS NASA Headquarters Washington DC, 20546 0001 USA Dear Dr. Huntress, Thank you for your prompt letter regarding the launch of SOHO. No doubt, the decision we took is the most rational one, and offers the best guarantees of success. The Project will comply with your request to inform the SOHO international team about the new date and explain the rationale behind it. On another topic, as you may remember, during our meeting in Austria you promised to write me officially concerning Ulysses extension beyond 1995. I would myself be very happy with what you said, however, on 7-8 November 1994 we will have our next Science Programme Committee meeting and the SPC would like to be informed about the NASA position regarding the Ulysses mission extension. An official statement from you would help unblocking the funds for the extension. I want to take this occasion to tell you how pleased I am that you could attend the Survey Committee meeting in Rome. I assume that Carl Pilcher told you how the meeting was concluded, much to the satisfaction of all participants. I also believe that you received the Information Note we prepared for the press after the meeting. I should add that I am very happy that you appointed Carl to observer on behalf of NASA. He attended the whole meeting and gave a much appreciated personal contribution. I am sure that in his new capacity of Executive Secretary to IACG Carl will be able to bring new life to the Group in this very important year 1995. Yours sincerely, Dr. R. M. Bonnet Director of Scientific Programme

Bonnet Director of Scientific Programs European Space Agency 8-10 rue Mario-Nikis 75738 Paris Cedex 15 FRANCE Dear Dr. Bonnet: Thank you for your letter of October 12, 1994, requesting information about the NASA position regarding the Ulysses mission extension. I am very pleased to report that barring any unforeseen circumstances that we will be able to continue the Ulysses mission through another set of polar passes. This extension offers the unique opportunity to observe the high-latitude behavior of the sun at solar maximum and to dramatically improve the database of gamma-ray burst locations. NASA intends to continue operating all missions that will continue to return new science, as long as we can do so while allowing a stimulating program of new missions and keeping within the budget constraints presented to us by the Administration and Congress. Since our budget is approved on an annual basis, we cannot make any guarantees. However, the Ulysses Maximum Mission is very high on our list of priorities, and the prospects look excellent for realizing its extension, provided NASA can maintain a healthy space science budget. I congratulate you on the celebration activities and press coverage arranged by ESA during the Ulysses south polar pass in mid-September 1994. We need to continue building public support for our space science missions, and I expect NASA to take advantage of the north polar pass in September 1995 to reach out again to the public. Sincerely, Wesley T. Huntress, Jr. Associate Administrator for Space Science

European Space Agency 8-10 rue Mario-Nikis 75738 Paris Cedex 15 FRANCE Dear Dr. Bonnet: In response to your March 31, 1995, letter to Dr. Huntress on behalf of Mr. Luton, I am pleased to extend the NASA-ESA Memorandum of Understanding (MOU) for Ulysses. However, NASA plans to proceed by the conclusion of six successive yearly renewals, governed by Articles 13 and 20 of the NASA-ESA MOU for Ulysses. If either side has the intention of terminating the MOU, it will endeavor to notify the other at least six months before the following yearly renewal. I propose that this letter, along with the MOU signed in 1979, your letter of March 31, 1995, and your affirmative reply to this letter, constitute our agreement to extend the Ulysses mission. I look forward to continued cooperation between our two agencies. Sincerely, John D. Schumacher Associate Administrator for External Relations
