To the Editor:

I am not a rocket scientist, but Dave Reed is. Dave graciously pointed out an error in my report in last week’s Mosquito concerning the problem of how he and his colleagues at mission control managed to find the lost lunar module in the Apollo 11 mission. The simple correction to what I reported was actually an elegant solution to the problem of finding the Eagle. Instead of relying on the sextant, Dave and his colleagues asked astronaut Buzz Aldrin to run an early rendezvous radar check so they could receive telemetry data as they tracked the orbit of the command module from horizon to horizon. This process produced the data they needed to run a rendezvous radar problem in reverse, which yielded the correct landing site and liftoff time for the lunar module. In simple terms, the sextant may have provided a good view, but the problem of locating the Eagle on the moon was actually solved on the ground by calculations run with data obtained through radar.

Ladies and gentlemen, this really is rocket science, and I apologize for my error willingly and with deep admiration to trajectory specialist Dave Reed. The United States is truly fortunate that he and his colleagues were at the controls in Houston during the Apollo missions.

Tennis courts a mess

To the Editor:

It is more than a bit discouraging to arrive at the Carlisle public tennis courts on a beautiful Sunday with the intention of getting some exercise and finding that the windscreen has been defaced by someone with a spray can and that the facility has been used by people who are apparently unable to distinguish a tennis court from a trash receptacle.

I needn’t tell most of you that these courts are public property, paid for with our tax dollars, and they are there for the enjoyment of all of us. But the old story of a few spoiling it for the many unfortunately applies here; the court area currently looks like it belongs in the South Bronx, not in Carlisle. If the abuse of the tennis courts and surroundings can’t be brought under control, I suggest that the town needs to find a way to restrict access to them. I recognize that there are no perfect solutions, but regrettably, the idea of good citizenship in a fine community like Carlisle seems to elude some of us, and the current policy of open and free access to the courts isn’t working.

This may seem like a trivial issue to some, but I would disagree. This sort of behavior is anti-social (if not outright illegal) and, if tolerated, can lead to more serious forms of the same behavior.

Birthday celebration for Center Park

To the Editor:

Come to Center Park on Old Home Day to celebrate the park’s second birthday. At 2 p.m. sing “Happy Birthday” with the Second Wind Quartet and enjoy the foot-tapping music of the Ancient Mariners Dixieland Band. Delicious cake and ice cream will be served.

As you step into the park, you will be surrounded by beautiful plantings in bloom. Teak and granite benches offer a comfortable resting spot for taking in the whole scene. Daylilies, astilbe, geraniums, sedum, coral bells, rhododendron, weigela, lilac and many other visual treats await you. Each day brings new delights as the progression of blossoming continues throughout the spring and summer in accordance with the five-year plan.

All are invited to meet at Center Park!

Take care where you dump

To the Editor:

As we enter the busy landscaping season here in Carlisle, the Conservation Restriction Advisory Committee (CRAC)would like to share a few reminders about the disposal of grass clippings, tree trimmings and other yard waste.

As fellow neighbors and co-residents of this community, we are each responsible for properly disposing of yard waste on our own property. That means it is not acceptable to dump yard waste on a seemingly unoccupied piece of land. Many of those “unoccupied” pieces of land in fact are public or semi-public conservation lands or are privately owned and protected by a Conservation Restriction that prohibits such dumping. These lands are meant to be preserved and protected in their natural state for our common enjoyment.

Please also remember to instruct any landscaping contractors where and how they should dispose of the yard waste from your property. Unfortunately, in recent years several incidents of contractors dumping waste on conservation and conservation-restricted lands have occurred, much to the chagrin and embarrassment of those who hired them.

We and your neighbors thank you for your cooperation.
