Space is a dangerous place. not only because of meteors (流星) but also because of rays from the sun and other stars. The Atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

Dear Edward,
I have been very busy recently with some really exciting new developments．If you visit my main website you will see various new items there．
The first is a tab called Food for Thought．This is a short daily email which raises a question or makes a statement or provides something for you to think about．Some regular readers may find these emails quite basic．However, you would agree with me that there are many people who reject anything spiritual simply because it means venturing(冒险进入) into the unknown．
There is also a tab called Please Help Me．I will be hosting tele-discussions soon-yes, and I am really excited about that!
Here I ask you to propose topics for tele-discussions．If you are concerned about missing out, don’t worry．The proceeds will be recorded and made available as MP3 recordings．Please let me know what burning issues you have or what you are curious about．
I am providing a free mystery gift to the value of £9.95 for each successful suggestion． And please don’t think your issue is meaningless-there may be a number of other people who may have the same issue．
You may not be aware that I have also published a number of guided meditations(思考) on-line．Please have a look at this website for a free guided meditation as well as an explanation of what meditation is about．
And watch this space for more exciting things to come in the next month．I am now in a space where my hobby has become my work-how lucky can a girl be!
I also want to thank you for your support and interest over the past years-you have helped me immensely on my own journey．
Love and Light,
Elsabe
64．What does the item “Food for Thought” mainly focus on?
