Moon rocks take out Red Bank High School-NASA mania hits

Lunar Sample from Apollo 16 Mission

• Launch Pad: Florida, USA (Kennedy Space Center)

• Launch Date: April 16, 1972

• Lunar Landing: April 21, 1972

• Mission Duration: 11 d 01 h 51 mins.

• The astronauts brought back 94.7 kg of lunar samples from the moon.

Moon Rocks

We used MoonZoo to help train our eyes to learn to identify craters. We mapped over 1251 images in 8 days.

To start: Imagery- how to capture the image, where to capture the image, and how to use the image.

We downloaded imagery from “LROC” and LO orbiters- this took a while and a lot of false starts. We finally found on the internet.We used NASA Article technical paper from NASA to aid in our choice of imagery and how to proceed.

How We Got the Imagery

Eureka!

The Image!!! Imbrium, you never looked so beautiful!

- We used 24 memory flash drives to divide up the swathes.

- 19 swathes covering 9,630.4754304 square kilometers in the Southeastern Imbrium Basin

How we set up our GIS format

• Includes the name of our swathe, which is our work base

• Also includes different names of objects found on the swathe

• Includes names of objects found, distinguished in colors.

• Names are selected to identify objects of focus.

How We Worked!!

Mrs. Keith is a real task master!

Over 3 weeks 23 students (Scientific Research) & 1 teacher put in 30 hours- we mapped over 55,000 craters

At times it seemed like all we did at Red Bank was map craters on the moon.

WORK! WORK! WORK!

GIS Hits Red Bank

But mayhem soon followed:1. GIS crashed twice, and had to

reload(which took 8 hours each).2. We thought we had lost $30,000

of GIS Software-the search was on!3. Power went out4. Data crashed laptop5. Data when printed took up over

1,100 sheets of paper, we stopped at 460.

6. Twitter knows about us! In England and Canada.

7. Data corruption on ‘stick’ 248. Can we take a picture and not

have theCamera stolen!9. 4 months of begging to get free

softwarefrom Virginia GIS.

Technical Issues We Faced With Imagery

1.) Lining up pictures with dots to make swaths2.) Issues when we were downloading data from LROC was compression data to make swathes and from them not to pixilate or become fuzzy3.) Last 2 swathes from Sea of Serenity had Long and Lat problems

1.

Figure 1

When we downloaded the crater imagery in order to use the images we had to first turn pictures 90° Clockwise

Then we had to turn an additional 90° Clockwise again until the original image had been rotated a total of 180° Clockwise from its original position

Projection Issues matter: We put swathes in the southern part of the Imbrium basin

to make the projection more rectangular. Better data in the long run!

Still swathes were smaller at the top and wider at the bottom more due to curvature of the moon even with cylindrical projections to lessen long/lat issues.

Sinusoidal Projections allow us to have true and accurate diameters of craters.

The name for the place of the discovery is Ilem mountains in Russia Metallic to sub metallic metal generally iron black meaning that the lava that formed the south eastern portion of Imbrium had to be around 1800ºC or greater during eruption.

So, what is

trask?......

What is the Trask Method?

The Trask Method is a way of determining the ages of craters based on these assumptions: Newly formed craters appear sharp

with raised rims and rayed ejecta. Craters are subdued and destroyed

eventually by meteorite impacts. Small craters are eroded faster and

disappear in less time than large craters.

The Relative date of our swathes was: we found craters in the Copernican time interval of 1 and 3. the majority of our impact craters (32,007) were between 50 and 500 meters in diameter at 78.1%. 17.9% of our craters fell between 10 to 50 meters.

New Swathe’s Location

What Did We Learn?

The age of the Archimedes crater inside the south eastern Imbrium 1.8-2.75 Copernican

The age of the western Serenity crater 2.5-4.3 Copernican 55,000 craters mapped The different types of craters: Bright Whites, Dark Haloed,

Compound, Simple. Area mapped totals: Imbrium 9,630.46 sq Km (5,778.4 sq. miles) Serenity 2,156.5 sq Km (1,293.9 sq miles) All areas mapped total: 11,786.9 sq Km (7,o72.11 sq miles) The type of rocks in the Archimedes crater is ILeminite The melt temperature of rocks on the moon in Archimedes 1800ºC

or 3272ºF How to use GIS to map the moon Most craters in both areas fell between 50-500m-wih 78.1% in

Imbrium and 67.1% in serenity Cross Sections: 1,500 ft rim walls in the southern portion of Imbrium Comparing like areas for best data: Old Area: 2012.4 km New

Area:2156.5 km

Where do we go from here?

1. Develop a DM Model of swathes that went through the rim wall of Archimedes to see elevation and slump patterns

2. Get Data for 3-D Modeling, 50% overlap needed

3. Get swathes outside the Imbrium. The whole perimeter! We had to stop at 2! For times sake

4. Look at statistical data for more trends to answer questions of why so few craters in 500-1000m? 1000m-5000m?

5. the 0-10 – we think our resolution or picture would not let us see and the 5000-10000m are really rare.
