June 13, 1990 (Phone: 202/453-9183) RELEASE: 90-81 NASA ANNOUNCES NEXT STEPS IN SPACE EXPLORATION OUTREACH PROGRAM NASA today has taken the next steps in its Space Exploration Initiative (SEI) Outreach Program to solicit innovative ideas on how to return to the Moon permanently and to begin human exploration of Mars. NASA Administrator Richard H. Truly announced the Outreach Program on May 31. The steps included a mass mailing from Truly to institutions and individuals, the announcement of a telephone number for public requests for response packets and publication of an announcement soliciting ideas in the Commerce Business Daily, which reaches both aerospace and non-aerospace industries. In a personal solicitation, Truly sent more than 3,200 letters to presidents of U.S. colleges and universities, deans of engineering schools, chairs of college and university science and engineering programs, presidents of science and engineering professional associations and others. He asked for ideas on mission concepts and their architectures and for ideas on the systems and technologies required for travel to the Moon and Mars and for living and working productively on both worlds. His letter included a response packet to be forwarded to the RAND Corp. in Santa Monica, Calif. NASA asked RAND to conduct an initial analysis and evaluation of the responses. RAND has established a toll-free telephone number for requesting an SEI Outreach response packet. The number is 1-800/677-7796. In announcing the SEI Outreach Program, Truly said that NASA would "leave no stone unturned to reach out to the very best and brightest in our nation" to gather information, concepts and data to carry out SEI. ------------------------------ Date: 15 Jun 90 14:30:13 GMT From: vtserf!jarrell@uunet.uu.net (Ron Jarrell) Subject: Re: Space Sail Race In article <1990Jun15.085816.28714@utzoo.uucp> henry@utzoo.uucp (Henry Spencer) writes: >is not a silly frill.

Right. And I guess you find Antarctica terribly boring and unexciting since men have been there, and find Mt Everest terribly boring and unexciting since men have been there, and would find sailing through Tierra del Fuego terribly boring and unexciting since men have been there... I've been watching this discussion, and I find the attitude that 'the only worthwhile things to do are those which haven't been done' rather distressing. If that were the common attitude, there would never be any progress -- because nothing would ever get improved, refined, developed.

No, the real goal of the sail race is to publicize the 500th anniversary of Columbus's landing. In that context, doing even a little bit of science is not a silly frill. The original RFP made it quite clear that things like publicity were just as important as technical issues. The MIT folks seem to have overlooked this... I have also heard some doubts expressed about things like the MIT group's mass budget for communications gear, but I have not seen details. -- As a user I'll take speed over| Henry Spencer at U of Toronto Zoology features any day. -A.Tanenbaum| uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ Date: 16 Jun 90 00:04:48 GMT From: sun.udel.edu!salamon@vax1.udel.edu (Andrew Salamon) Subject: Equations and numbers?
