Dear discuss-lfm members,

Whew.... lately it has been a *challenge* keeping up with all the 
Challenge Questions and the CQ answers that have poured into my mailbox.
That's not a complaint, in fact we are thrilled so many students are
taking on the CHALLENGE!  If you haven't received a personal note
stating that your answer has arrived, please forgive me as time
to respond to individuals has run short.

CQ #5 was posted last Thursday in updates-lfm and it's answer was
already posted in the updates. (opps, that was a bit early!!)
Legally, I will still accept answers until 6pm Central tonight.  
(Just hope no one gave the answer away!)

I have collated the answers for CQ#4 and it will be posted on our
web site shortly.  It was so hard to select winners this time as
so many students had cracked the puzzle that I had to put the names
into a drawing. Wow, these kids are smart!

CQ #6 was posted on November 19th and will be due by 6PM Central on
November 26th!!  Here's the final question:

The Mars Global Surveyor (MGS) took off in November and is
scheduled to arrive at Mars between Sept 11 and Sept 22, 1997.
The Mars Pathfinder (MPF) takes off sometime in December. No
matter when it leaves, it is scheduled to arrive on July 4, 1997.

Why does the Pathfinder get to Mars earlier, even though it leaves
later.

And how can the Pathfinder have an exact arrival date even though
its liftoff date may vary?


WHEN SENDING YOUR ANSWERS PLEASE INCLUDE STUDENT'S NAME(S), GRADE/AGE, 
SCHOOL/LOCATION AND TEACHER'S NAME.

Thanks,
Jan Wee
