The letter to 270,000 people who sent their messages on Mars Exploration Probe, "NOZOMI"

Ladies and Gentlemen:

I regret to report to you that "NOZOMI" that has traveled in solar system interplanetary space with your names onboard for a little over five years after departure from earth in July of 1998 has come to give up its injection into orbit around Mars by mission control's final decision, at 8:30pm December 9, 2003 (Tue), after having confirmed non-recovery from operational malfunction in spite of the hardest struggling restoration operation by the mission team. Following its decision, mission control center sent a command to change the probe's trajectory from 8:45pm to 9:15pm of the day, in order to lower the impact percentage of colliding with Mars. As a result, "NOZOMI" will pass by 1,000km above Martian surface on December 14 and will escape from gravitational sphere of Mars on December 16 to continue on traveling along orbit around the sun with your names onboard.

A number of invaluable experiences and achievements we have obtained from "NOZOMI" as its first interplanetary exploration probe of Japan, such as long distance telemetry, control of trajectory, designing of probe and operational technology, etc. were all totally applied to "HAYABUSA" launched in May of this year, and will contribute a great deal to the advancement of future solar system interplanetary exploration program of Japan. Although science observation instruments onboard have made some achievements in interplanetary space as I occasionally reported on our homepage, they could not, heartbreakingly, fulfill the original objectives.

Above all, I must most regrettably apologize from the bottom of my heart for not having been able to send your names to the final destination of Mars.

As I look back at the campaign movement of "Send your names to Mars!" your messages with your names on each postcard overwhelmingly moved and encouraged our staff members of the institute and graduate students challenging to solve the mysteries of solar system and whole universe, as along they were engaged in incredible amount of works to cut out each name out of 270,000 applications.

There was a lovely postcard scribbled by then five-year old boy with the names of grandfather and grandchild, "I want to be always with my grandpa" in a 2cm x 6cm square space.

There was a heartrending postcard with warm love of a mother who lost her baby, "This is a name of my one-year old child who died last year. Please make him/her a real star."

I, as an original proposer of this campaign, ran my eyes through each one of the postcards. All those thankful messages that reflected each sender's life style and life itself so much encouraged the former institute staffs to advance further with confidence in convincing themselves, "there are numerous number of people with whom we can share the feelings of space".

At the last spurt of repair operation of "NOZOMI" from autumn through to December of this year, we received many cheering e-mails and telephones, "Come on! Hold on! NOZOMI". How encouraging those warm messages were to the "NOZOMI" mission team trying hard to recover conversation contact with "NOZOMI"!

Though the final objective was not achieved, "NOZOMI" team still continues restoration efforts for a while. Whatever outcome it may bring, the first Japanese interplanetary exploration probe made with every possible effort will circle around the sun with your names semi-permanently. In the last place, we would like to extend our heartfelt thankfulness as well as sincere apology to 270,000 people at this time, wishing that "NOZOMI" would, from heaven above, watch and protect our future life and give encouraging power to all creatures on earth and to our beloved country. Ladies and gentlemen, we would like to thank you very much once again and expect the same favor of yours to be given to our future activities as well.

Yours very truly,
