Using an inquiry-based learning approach, the apps challenge middle-school students with investigations and quizzes based on the students’ explorations of each interactive unit.’

3- 3D Molecules Edit & Test
‘“3D Molecules Edit & Test” allows one to build and manipulate 3D molecular models of organic and inorganic compounds. The key features of “3D Molecules Edit & Test” are 3D printing support and the “Test yourself” mode that allows learners to check their knowledge of the 3D structure of molecules. This is a valuable tool for chemistry students when learning about molecular bonding and orbitals with the aid of 3D visualisation. The app is great for any high school or college student in chemistry courses.’

4- Toca Lab
‘Welcome to Toca Lab! Explore the colorful and electrifying world of science and meet all 118 of the elements from the periodic table…Toca Lab is a place for playing and having fun, and with it we hope to inspire kids to explore science. While the periodic table in Toca Lab is accurate, the way new elements are created is not. Instead, it’s a fun way to experiment, discover and create curiosity in the world of science. Toca Lab is just a starting point for further exploration!’

5- LabInApp Physics Demo
‘LabInApp is a 3D, interactive virtual laboratory tool that focuses on heuristic approach of understanding science. This heuristic ideology facilitates students and teachers to perform science experiments on computers or mobile devices, and eliminates the physical barriers of actual laboratory.

SPACE TRAVEL

How bright is the future of space food

Honolulu HI (SPX) Feb 27, 2017

Research at the University of Hawai?i at Manoa could play a major role in NASA’s goal to travel to Mars in the 2030s, including what the astronauts could eat during that historic mission.

A trip to Mars and back is estimated to take about two and half years, and ideally, their diet would be healthy while requiring minimal effort and energy. UH Manoa mechanical engineering student Aleca Borsuk may have the solution.

“I picked a really hearty, heat tolerant, drought tolerant species of edible vegetable, and that is amaranth. It’s an ancient grain,” said Borsuk, who determined that she could significantly increase the edible parts, which is basically the entire plant, by changing the lighting. “If you move the lights and have some of them overhead and some of them within the plant leaves, it can actually stimulate them to grow faster and larger.”

This is without adding more lights and by using energy efficient LEDs. Thanks to Borsuk’s work with lighting, plants could play an important role in the future of space travel.

“This plant would do the same thing that it does here on Earth, which is regenerate oxygen in the atmosphere,” said Borsuk. “It also can provide nutrition for the astronauts and if you can imagine being away from Earth for many years, you know tending something that’s green would have a psychological boost as well.”

A 2013 UH Presidential Scholar, Borsuk presented her research at the Hawai?i Space Grant Consortium Spring 2016 Fellowship and Traineeship Symposium and at the 2016 American Society for Horticultural Science Conference in Florida. She is mentored by UH Manoa Tropical Plant and Soil Sciences Associate Professor Kent Kobayashi, who is also an American Society for Horticultural Science Fellow.

International Art Contest for Students   Leave a comment

Mars Society to Hold Int’l Student Mars Art Contest

The Mars Society announced today that it is sponsoring a Student Mars Art (SMArt) Contest, inviting youth from around the world to depict the human future on the planet Mars. Young artists from grades 4 through 12 are invited to submit up to three works of art each, illustrating any part of the human future on the Red Planet, including the first landing, human field exploration, operations at an early Mars base, the building of the first Martian cities, terraforming the Red Planet and other related human settlement concepts.

The SMArt Contest will be divided into three categories: Upper Elementary (grades 4-6), Junior High (grades 7-9), and High School (Grades 10-12). Cash prizes of $1,000, $500 and $250, as well as trophies, will be given out to the first, second and third place winners of each section. There will also be certificates of honorable mention for those artists who don’t finish in the top three, but whose work is nevertheless judged to be particularly meritorious.

The winning works of art will be posted on the Mars Society web site and may also be published as part of a special book about Mars art. In addition, winners will be invited to come to the 20th Annual International Mars Society Convention at the University of California, Irvine September 7-10, 2017 to display and talk about their art.

Mars art will consist of still images, which may be composed by traditional methods, such as pencil, charcoal, watercolors or paint, or by computerized means. Works of art must be submitted via a special online form (http://nextgen.marssociety.org/mars-art) in either PDF or JPEG format with a 500 MB limit. The deadline for submissions is May 31, 2017, 5:00 pm MST. By submitting art to the contest, participating students grant the Mars Society non-exclusive rights to publish the images on its web site or in Kindle paper book form.

Speaking about the SMArt Contest, Mars Society President Dr. Robert Zubrin said, “The imagination of youth looks to the future. By holding the SMArt Contest, we are inviting young people from all over the world to use art to make visible the things they can see with their minds that the rest of us have yet to see with our own eyes. Show us the future, kids. From imagination comes reality. If we can see it, we can make it.”

Mission Summary – Crew 174

Mars Desert Research Station End of Mission Summary

Crew 174 – Team PLANETEERS

 

Team PLANETEERS (All Indian Crew):

Commander:  Mamatha Maheshwarappa

Executive Officer/Crew Scientist:  Saroj Kumar

Engineer/Journalist:  Arpan Vasanth

GreenHab Officer:  Sneha Velayudhan

Crew Health & Safety Officer/Geologist:  Sai Arun Dharmik

Success occurs when your dreams get bigger than your excuses

 

The Solar System is a tiny drop in our endless cosmic sea (Universe). Within our solar system, a very few planets host an environment suitable for some life forms to exist. The closest one being Mars after the Earth, following the success of rovers such as Spirit, Opportunity, Curiosity and several space probes, the human understanding of the planet has reached new levels. The next important aspect is to find out if there exist any life forms or if the planet had hosted any life in the past. Although the rovers send out a lot of information about the planet, so far humans have not found anything substantial. With advancements in science and technology by organizations such as NASA, ESA, ISRO, CNSA along with private industries such as SpaceX manned mission to Mars seems to be within reach in a few years. To carry out successful missions humans will have to develop key tactics to cope up extreme conditions, confined spaces and limited resources. Team Planeteers (MDRS Crew 174) is the first all Indian crew consisting of five young aspirants from different domain who have come together to embark on a special mission in order to develop such key tactics. The crew was successful in executing the planned experiments. The key for their success is the temperament and dedication shown by each individual and fixing small issues immediately. Since all the members were of same origin, food and cultural aspects was an advantage. Going forward the team is planning out for outreach activities. As a part of QinetiQ Space UK, Mamatha will be involved in outreach, education and media activities (TeenTech & STEMNET). Similarly, Saroj and Sneha will be conducting STEM outreach activities at Unversity of Alabama and Rochester Institute of Technology respectively.

Research conducted at MDRS by Crew 174:

 

  1. Characterizing the transference of Human Commensal Bacteria and Developing Zoning Methodology for Planetary Protection

The first part of this research aims at using metagenomics analysis to assess the degree to which human associated (commensal) bacteria could potentially contaminate Mars during a crewed mission to the surface. This involved collection of environmental soil samples during the first week of the mission from outside the MDRS airlock door, at MDRS airlock door and at increasing distances from the habitat (including a presumably uncontaminated site) in order to characterise transference of human commensal bacteria into the environment and swabbing of interior surfaces carried out towards the end of the mission within the MDRS habitat to characterize the commensal biota likely to be present in a crewed Mars mission. In the interests of astrobiology, however, if microbial life is discovered on the Martian surface during a crewed mission, or at any point after a crewed mission, it will be crucial to be able to reliably distinguish these detected cells from the microbes potentially delivered by the human presence.

The second part of the research aims at testing the hypothesis that human-associated microbial contamination will attenuate with increasing distance from the Hab, thus producing a natural zoning.  The previous studies hypothesize that there may be relatively greater contamination along directions of the prevailing wind because windborne particles or particle aggregates allow attachment of microbes and help to shelter them against various environmental challenges, e.g. desiccation, ultraviolet light, etc. Efforts are afoot to try to develop a concept of zones around a base where the inner, highest contamination zone is surrounded by zones of diminishing levels of contamination occur and in which greater Planetary Protection stringency must be enforced (Criswell et al 2005).  As part of that concept, an understanding of what the natural rate of microbial contamination propagation will be is essential.

a. Sample collection process:

Two sets of samples were collected as the analysis will be carried out at two different stages.

i. Samples of the soil outside the MDRS were collected aseptically into sterile Falcon tubes. Sampling sites included immediately outside the habitat air lock (with presumably the highest level of human-associated bacteria from the crew quarters), at increasing distances from the airlock along a common EVA route (to track decrease in transference with distance), and at a more remote site that ideally has not previously been visited by an EVA (to provide the negative control of background microbiota in the environment).

Figure 2 Soil Samples collected at increasing distances from the Airlock

 

ii. Various surfaces within the crew quarters were swabbed using a standard sterile swab kit to collect microbes present from the course of normal human habitation. These included door handles, walls, table surface, airlock handles, staircase, working table, computer. This did not expose the science team to additional infection risks (such as not swabbing toilets).

Figure 3 (a) Sterile Swab Kit (b) Internal swab collection (working table)

Sampling locations within the habitat and soil sampling sites during EVA were recorded by photographs and written notes. After collection, the samples were refrigerated at the MDRS Science lab, and then returned with the crew to London for storage and analysis. This is analogous to medical samples being collected from ISS astronauts and returned to Earth for lab analysis. The molecular biology sample analysis and data interpretation, including all the metagenomic analyses to identify bacterial strains present, will be conducted by Lewis Dartnell in collaboration with John Ward. The collaboration agreement is already in place and lab space and resources confirmed. The analysis is carried out in two different stages:

 

a. Stage 1 Analysis:

The first set of samples will be tested using off-the-shelf simple tests for the presence or absence of human associated microbes, namely coliforms.  These are simple to use and give a yes/no answer, so plots will be made of yes/no results with distance from the hab in different directions.  This could be correlated with prevailing wind directions and/or to show common human pathways from the hab versus directions in which people typically don’t go.

b. Stage 2 Analysis:

The second set of samples (internal swabs) will not be cultured or otherwise processed back on Earth (as culturing of human commensurate and environmental microorganisms could present a biological hazard to the MDRS astronauts). All sampling materials and storage containers were provided by the study, and thus will require no consumables or other resources from the MDRS. All sample collection pots and sampling materials will be removed by the study scientists, and the sampling process itself (small soil samples and surface swabs) will not impact the MDRS habitat or its natural environment.

 

  1. Zoning and sample collection Protocols for Planetary Protection

 

Planetary protection is one of the major subjects that require immediate attention before humans travel to Mars and beyond. MDRS being one of the closest analogues on Earth with respect to dry environment on Mars was the best site to perform and simulate issues related to planetary protection. Our work on planetary protection was to simulate zoning protocol to be used to manage relative degrees of acceptable contamination surrounding MDRS and implementation of sample protocols while at EVA’s for soil sample collection, geological study and during hab support activities etc.

 

a. Zoning protocols for crew exploration around MDRS

During the mission, we extensively studied the zoning protocol in and around the hab and how contamination issues on Mars can be restricted.  On the first day on ‘Mars’ we used the geographical map of MDRS exploration area to formulate and characterize zones around the hab and the strategy for sample collection.

i. Zone: 1 (Area within Hab) – This area is believed to be the most contaminated with the human microbes.

ii. Zone 2 (About 20 meters from the hab) – This is the area where most of the hab support systems and rovers are parked. This zone is supposed to have less microbial contamination than hab but higher than Zone 3 and 4.

iii. Zone 3 (Beyond 20 meters but within 300 meters around the hab) – This area is considered to have regular human presence during an EVA. Soil samples of Zone 2a and 2b were collected for future analysis in lab to study human microbial contamination.

iv. Zone 4 (Special Region) – This area was considered to have insufficient remote sensing data to determine the level of biological potential. This area was marked as no EVA zone and can only be studied in detail by remote sensing data using satellites or drones.

 

b. Sample collection protocols

The crew studied the sample collection protocol requirements for all the activities such as soil sample collection, geological study and during the operations of hab support systems etc., this was to avoid forward and back contamination.  The protocols were planned to be initiated from the time a crew member leaves the airlock for EVA and until he/she returns from the EVA to Hab. During the EVA, the crew noted every experiment procedure and made sure there was no breach in spacesuits and no human microbial contamination during soil collection. The tools used for the soil collection were required to be completely cleaned and sterilized. The study of rocks on site during an EVA was one of the major challenges where it was realized that special tools were required to pick the rock samples without getting them exposed to spacesuit gloves. Using only gloves to pick rock samples could also rupture the spacesuits and thus there could be a decompression issue. Even with a detailed geological exploration map of MDRS and high resolution satellite imagery, it was noted that the use of drones can drastically reduce the human EVAs and lots of geological and terrain information can be obtained in a shot span of time. This step would heavily reduce the human EVA and thereby contamination issues to special regions where there could be a possibility of having a biological activity. Water, a major carrier of human microbes is proposed to be within the structures of hab. During the simulation, the crew made sure that there was no water spillage outside the hab.

 

  1. Development of New Techniques to Enhance Plant Growth in a Controlled Environment

A crewed mission to the Mars demands sufficient food supplies during the mission. Thus cultivation of plants and crops play an important role to create a habitat on Mars. There are some factors to be considered before cultivating crops on the Martian surface. First, the planet’s position in the solar system, Mars receives about 2/3rd of sunlight as compared to the Earth that plays a vital role in crop cultivation. Second, the type of soil used for crop cultivation should to be rich in various nutrients. Since the MDRS site is considered as one of the best analogue sites on Earth to simulate Mars environment, the experimental results of plant growth at MDRS was considered for this research. This research aims at growing fenugreek (crop that is rich in nutrients and grows within the mission time) to determine the effect of Vitamin D on the growth.

At MDRS, the fenugreek seeds were allowed to germinate for 2 days. In the mean-time, an EVA was carried out to collect soil from different parts on ‘Mars’. The soil was collected based on the colour and texture. Five types of soil, white (01), red (02), clay (03) coloured soil, course grey soil (04) and sand from river bed (05) were collected. Two set of experiment pots were made as shown in the Figure 4. Each had 15 pots, 10 pots with Earth soil (ES) labelled with different levels of Vitamin D (0- 0.9) and 5 pots of Mars soil (MS) labelled according to the area of the soil collected (0-5). One set of 15 pots was placed in the Green hab and the other in the controlled environment (under the Misian Mars lamp) after planting the well germinated seeds. The plants were watered twice a day in order to maintain the moisture in the soil.

Figure 4 Experimental Setup with Earth and ‘Mars’ Soil

The temperature and humidity levels were monitored twice a day throughout the mission both in the green hab and the controlled environment (Misian Mars Lamp). It was noted that there was a steep increase in the temperature in the green hab as the outside temperature was high that inturn decreased the humidity in the green hab drastically. The situation was managed by switching on the cooler and then by monitoring the heater thermostat. The plants were watered with specific measurement of Vitamin D every day. The experiment was successfully completed by monitoring the growth regularly, it is evident that humidity and temperature impacts the growth of plants. The plants in the green hab showed more growth of primary root than the secondary, the leaves were normal in colour and growth. In the controlled environment, the root growth was fast, the plants developed many secondary roots in few days. The plants looked healthy, the leaves were dark green and bigger than the ones in the green hab as seen in Figure 5.

Figure 5 Plant growth in (a) Misian Mars Lamp (b) GreenHab

In conclusion, the graphs were plotted for the root growth for the Earth Soil with Vitamin D in the green hab and the controlled environment from Sol 08 to Sol 13. The graphs indicated that the low level of Vitamin D (0.1) enhances root growth in the green hab. Under misian Mars lamp, the growth rate is high for ES 0 (without Vitamin D).   Readings tabulated for the Mars soil was plotted on daily basis but, after few days it was noted that there was neglibile growth in the Mars soil. The graphs plotted for few days are as shown in the Figure 6.

  1. Study of magnetic susceptibility of the rocks and their comparison

 

The primary objective was to study the magnetic susceptibility and magnetic minerals of the rock samples collected and compare them with multi-spectral remote sensing data back in the lab. MDRS contains a range of Mars analogue features relevant for geological studies. It contains a series of sediments derived from weathering and erosion from marine to fluvial and lacustrine deposits containing also volcanic ashes (Foing et al. 2011). With the preliminary understanding of the MDRS geographical exploration area and identification of potential targets, the lithology can help us decipher the structural history of the region, with understanding of genesis of such rock types and aid exploration efforts. The previous studies done at MDRS reveals that the magnetic susceptibility did not vary significantly near the Hab. Hence, the locations of various geological formations far away from the hab were selected to study the distribution of magnetic minerals. The selected locations for the same were sedimentary outcrops, cattle grid, burpee dinosaur quarry, widow’s peak and near the Motherload of concretions.

We found layers of horizontally bedded sandstone and conglomerates, sandstones and siltstones. Some of them seem to have inverse grading which could have been created by the debris flow. Gypsum and lichens were spotted around the area of sedimentary crops. In the next visit to Motherload of concretions, we have seen a variety of lichens: yellow, black, orange and grey. And in the Cattle grid region, colors of mudstone and conglomerates bands of rich cream, brown, yellow and red were found. The basalt samples were collected from the gravel in the cattle grid region and from the URC north site (porphyr) to be studied in the lab. Near the widow’s peak, shales were found along with gypsum shining bright, distributed around that area. Most of the region was covered mostly with loose soil. The locations of all the samples collected from different regions were marked with the help of GPS. The magnetic susceptibility of rock samples were measured and documented them using the magnetometer in the science lab. Inspection of samples was possible with the microscope at the science dome, with 10X zoom as seen in Figure 4. They need to be studied in thin sections for better understanding and will be done on Earth under the guidance of specialists.

  1. Drone Experiment

‘Mars’ has a harsh environment that risks Extra Vehicular Activity (EVA). The main objectives of the drone experiment were:

a. To ease EVAs by understanding the scenario of a region that is hard to access by rover/ATV.

b. To simulate the application of drone in search of a crew member during an emergency situation and during loss of communication.

c. Video making and photography for outreach activities.

The first objective to make use of drone in isolated regions was successfully executed on Sol 07. Since it was the first trial, the drone was operated in beginner’s mode restricting the field of operation to 30m range. The crew was looking out for soil samples, when confronted by a medium size hill the drone was sent out to check for soil sample availability on the other side. The region looked to be same and it was easier for the crew to take a decision to abort the mission and move to a different location.

Execution date:                Sol 07 (Earth date: 02/05/2017)

GPS Satellites:   13

Flight mode:                     Beginner’s mode of max 62 FT altitude and within 30m range.

 

The second objective was to simulate an emergency situation when one of the crew lost communication with other member during EVAs. The beginner mode range was too less and hence the drone was operated in advanced mode to search the missing crew member. The mission was successful in identifying the crew member.

Execution:         Sol 11 (Earth date: 02/09/2017)

GPS Satellites:   14

Flight mode:                     Advanced mode with 121 FT altitude and 500m range.

Talking About World Gardens   Leave a comment

Dr. Jose Barbosa, loading up produce.

This year, students in the College of Arts and Sciences (CAS) have been able to get their hands dirty while putting down roots in the community – literally!

The UTC Teaching & Learning Garden began this past spring, taking students out to learn about raising food in an urban environment. In total this year, the Garden was able to raise 2100 pounds of produce that was donated to the Chattanooga Community Kitchen.

“And that’s pesticide free during an extremely difficult summer without rain. The students are learning more than they could have imagined. More than any of us could’ve imagined,” said Dr. Joe Wilferth, UC Foundation Professor and Associate Dean of the College of Arts and Sciences.

The last harvest of the year, approximately 400 pounds of produce, was delivered to the Community Kitchen in time for Thanksgiving.

“They had quite a Thanksgiving feast!” Wilferth said.

UTC student Chloe Dente

The Teaching & Learning Garden is more than just a community garden, however. The Garden is a hands on learning space that addresses topics that UTC students care about, like sustainability, gardening, local food economies, health and food production

Dr. Jose Barbosa, Associate Professor of Biology, Geology, and Environmental Science in the College of Arts and Sciences, is the primary faculty sponsor for the project, providing oversight and planning of the space. Most of the students who worked in the garden were earning class credit in Barbosa’s Urban Gardening classes. However, students not in Barbosa’s class also volunteered.

“The garden is open for academic use to faculty and students all across CAS. In the future, faculty are invited to approach Dr. Barbosa or me if they wish to integrate the garden into their coursework,” said Wilferth.

Wilferth looks forward to the opportunities for interdisciplinary and multidisciplinary work both within CAS and across the campus that the Teaching & Learning Garden provides. Approximately 125 students in Art, Biology, English, Environmental Science, Political Science, and Sociology all participated in the project since spring.

“The garden may be used by specific courses across the CAS as it exemplifies experiential and hands-on learning. It could be expanded in the future to include courses and experiential learning opportunities in other colleges on our campus—e.g., courses in other colleges that focus on food production, nutrition, health and wellness, environmental literature, as well as the sociopolitical and socioeconomic factors involved in food production and food quality,” Wilferth said.

A bountiful harvest of radishes.

The Garden is located behind the outfield wall of Engel Stadium, just around the corner from the Value Lot. This past March, the folks in Facilities donated their time and resources to clearing the land, which wasn’t previously in use, for the Garden.

“This is an ideal space because of its proximity to campus. The shuttle service can take students to and from the garden. Class meetings wherein students visit/work in the garden will not require additional time, nor will the students’ academic schedules be interrupted,” Wilferth said.

This year, all of the produce to come out of the Garden went to the Chattanooga Community Kitchen, but in future years some of the food may also end up in students’ stomachs.

“In the future, we are considering ways to have something like a farmers market on campus where the proceeds might go to support student travel and undergraduate and graduate student research,” explained Wilferth.

The Chattanooga Community Kitchen would still receive at least a third of the harvest.

The Environmental Task Force, which oversees the “Green Fee” funds, supported half of the garden’s costs this year.

“This first year, of course, was the most expensive year simply because we had to get the garden going. We had to purchase tools, a storage facility, and more,” said Wilferth. “Other offices around campuses committed funds, too. Significant support came from both the Office of Undergraduate Research and Creative Activity and from the Vice Chancellor for Research and Dean of the Graduate School. In the end, this is a relatively cheap project that has potential for a big impact. We’re doing something exciting here. We’re literally growing!”
