Dear Mr. DiGregorio:
Thank you for contacting my office regarding NASA's Mars Climate Orbiter.
As you mentioned in your letter, I agree that NASA needs to answer serious
questions regarding the loss of the spacecraft. But, I truly believe that
our progressive exploration of space creates vision, hope, and promise for
the future of the United States.
The loss of the Mars Climate Orbiter is a setback for our space exploration
efforts but by no means a fatal step for our Mars science program. Thankfully,
NASA has learned from past mistakes and built a robust exploration program of
Mars that doesn't involve putting all of its mission eggs in one basket. Mars
Climate Orbiter is just one low-cost mission in a series, meaning our science
effort isn't dependent on this single spacecraft. I anticipate long-term success
despite this setback and look forward to working with NASA in determining how and
why this mission failed and ensuring that the appropriate corrective actions have
been taken.
Regarding the proposed Mars Sample Return mission, the National Research
Council's Space Studies Board convened the Task Group on Issues in Sample
Return in 1995 to address the following concerns:
- The potential for a living entity to be included in a sample to be returned from another solar system body, in particular Mars;
- The scientific investigations that should be conducted to reduce uncertainty in the above assessment;
- The potential for large-scale effects on the environment resulting from the release of any returned entity;
- The status of technological measures that could be taken on a mission to prevent the unintended release of a returned sample into Earth's biosphere; and
- Criteria for controlled distribution of sample material, taking note of the anticipated regulatory framework.
The findings and recommendations of the Task Group on Issues in Sample Return
were published in 1997. These findings are concurrent with your opinion that
the public should be openly informed of plans, activities, results, and associated
issues and are outlined in the executive summary portion of the study as follows:
- The most effective strategy for allaying fear and distrust is to inform early and
often as the program unfolds. Acknowledging the public's legitimate interest in
planetary protection issues, and thereby keeping the public fully informed throughout
the decision-making process related to sample return and handling, will go a long
way toward addressing the public's concerns.
I agree with the statements made in the National Research Council's study and remain
committed to keeping the American public informed and involved in the proposed Mars
Sample Return mission. Thank you again for contacting my office. I invite you to
follow the actions of the Science Committee on our web page at

F. JAMES SENSENBRENNER, JR.,
