Overview: This page describes the exhibit dedicated to Eleanor F. Helin. It is called The Helin Commemorative Exhibit: Searching the Sky for Dangerous Neighbors: Eleanor Helin and the 18-inch Telescope. This website explains who Eleanor was and what accomplishments she made that contributed to the world of astronomy. Explained in the text is that Eleanor was a planetary scientist who studied at California Institute of Technology (Caltech) and the Jet Propulsion Laboratory (JPL). During her studies she searched for Near Earth Asteroids and Near Earth Objects. The studies began in 1972 where she used an 18 inch telescope. She began studying with the Palomar Planet-Crossing Asteroid Survey (PCAS) which led to her discovery of the first Near Earth Asteroid on July 3, 1973. After accomplishing the Near Earth Tracking Project Eleanor was awarded the NASA's Exceptional Service Medal and "The USS Helin (NCC-1692), a starship in the Star Trek franchise, was named after her for 'having discovered an unprecedented number of asteroids and comets.'" The site goes on to explain more about her accomplishments as well as go into depth more about the famous Palomar 18-inch Schmidt Telescope.

Author: California Institute of Technology, and administered by Caltech Optical Observatories.

Accuracy: This information does seem accurate and up to date as it was updated only a couple of months ago. The site also contains pictures of display materials found at the exhibit that help provide an accurate view of what the exhibit contains. This site contains a lot of information on the female astronomer, what she has accomplished, when she accomplished those things, and also what the exhibit has to offer overall.

Readability and Clarity: The audience of this site can be anyone searching for information on Eleanor F. Helin or on this particular exhibit if they are looking for information on what it contains. The audience can be anyone who can read at Flesch Reading Ease of 8.2 and a Flesch-Kincaid Grade Level of 19.8. It is relatively easy reading with some words that are a little bit more on the "science side" that might need to be looked up for further explanation for a younger reader.

Ease of Navigation: This page is easy to navigate because there are bolded words that bring you to new links in case you need more explanation on them. There are also more links that go beyond the information of just Eleanor such as other exhibits. Also the site has general information such as links like Home, About Us, Visiting the Site, Guided Tours, etc.

Overview: The purpose of this page is to focus on the major accomplishments that Eleanor F. Helin made. Rather than focusing on who she was and how she became the astronomer she was, this site talks about why she made it into the WITI - Hall of Fame in 1998. One of the major discoveries by Eleanor was the (2062) Aten asteroid which helped take off for her International Near Earth Asteroid Survey. This went on through the 1980's and in 1997 shortly before entering the Hall of Fame; Eleanor was awarded the JPL Award for Excellence for her Near Earth programs. Eventually as technology advanced she used electronic sensors on a large telescope to start making more discoveries faster. At the end of the page there is also a video called Eleanor Helin: WITI Hall of Fame 1998 Induction Video- Women in Technology International which shows images and more vividly explains for her Near Earth project works.

Accuracy: The accuracy of this information is valid as it directly correlates with the information from the website previously mentioned in http://www.astro.caltech.edu/palomar/visitor/visitorcenter/helinCommemorative/. Also there is a video at the end with live new reporters during the time of her discoveries and even an interview with Eleanor F. Helin herself.

Readability and Clarity: The reading level of this site can be anyone who can read at Flesch Reading Ease of 17.1 and a Flesch-Kincaid Grade Level of 16.9. The context is not too complex besides the asteroids being named with numbers and non traditional English names.

Ease of Navigation: This site is easy to navigate as there is not much to it. At the top there is a bar with links to other options for the website that explains what it is all about. The only thing that can be distracting about this website are pop ups on the side and top that ask you to join the website. Other than that the text is clear and the video is easy to the click of a button.

Overview: This site directly lists all of her discoveries. In little boxes they list the name of the object discovered, the date the object was discovered, and what the object was. This is done so in boxes listed going down from oldest to newest discoveries. Some examples of those discoveries were 2062 Aten in 1976 (asteroid), 4363 Shkodrov in 1978 (a main belt asteroid), 3360 Syrinx in 1981 (Apollo and Mars crosser asteroid), 6456 Golombek in 1992 (amor asteroid) etc. A few of these discoveries even have pictures to portray a better description.

====Overview: This is site talks highly about how Eleanor Helin was a strong figure of a pioneer for Near Earth Objects. She studied and worked on projects in Geology and Planetary Scientists with another great pioneer to the world of astronomy Eugene Shoemaker at the California Institute of Technology. Then the site goes on to talk about her greatest discoveries such as the one named after her called The Fast-Moving Object Helin 1976 AA, (2062) Aten. Along with this were descriptions of the object, where it came from and when it was discovered. She collaborated with many other pioneers and together they all made great discoveries that have led us to be able to know and learn what we can today. Eleanor curved the pathway for us today to make the discoveries we can.====

Overview: This site is actually written by Eleanor F. Helin herself along with her other colleagues. As one of the founders of the Near Earth Asteroid project she goes on to describe what asteroids really are and their chance of colliding with earth in terms of numbers. Throughout this site Eleanor describes the results of the Near-Earth Asteroid Tracking (NEAT) program of the Jet Propulsion Laboratory of the California Institute of Technology. By 1998 45 NEA's (Near Earth Asteroids) had been discovered, which was only the beginning of her astronomical career. The site also contains a graph from the NEA tracking and the Spacewatch survey that shows the number of NEA's, the magnitude, and the diameter. This is a good site to further break down some of her work and to really go into depth about some of Eleanor's discoveries.

Accuracy: Being that the information on this site is written by the scientists and astronomers themselves helps readers to know that this information is very accurate. The site begins with a basic description of an asteroid and then as they go into further detail about their asteroid program they show a graph with the incremental number of Near Earth Asteroids, the diameter, and the magnitude. It is written in the year 2000 so some of the information may not be quite up to do date if the science has changed in the process.

Readability and Clarity: The content is clear and precise but there is a lot of reading on this site. The reading level of this site can be anyone who can read at Flesch Reading Ease of 28.3 and a Flesch-Kincaid Grade Level of 15.2.

Ease of Navigation: This site is easy to navigate as the paragraphs are clear and the information is in order accordingly. There is also pictures to help the reader better comprehend what is being said and at the end there are also references. This allows the readers to go look further into all the research that is displayed on this site.
