PERSEVERANCE: Rocketing to Mars with STEM
PERSEVERANCE: Rocketing to Mars with STEM GRADE LEVELS MISSION This activity is appropriate for grades 3-8. Design fins for a foam rocket. VOCABULARY MATERIALS LAUNCH VEHICLE: A launch vehicle provides the velocity » 30 cm piece of polyethylene foam pipe insulation needed by a spacecraft to escape Earth’s gravity and set it (for 1/2” size pipe) on its course for space exploration. » Rubber band (size 64) TRAJECTORY: The path followed by a projectile flying or » Duct tape an object moving under the action of given forces. » Scissors » Meter stick/ruler » Two 4x6 index cards ABOUT THIS ACTIVITY On July 30, 2020, at 4:50 a.m., an Atlas V-541 rocket was launched from Cape Canaveral Air Force Station, Florida. The Atlas V is one of the largest rockets available for interplanetary flight and delivering things into space. The rocket departed Earth at a speed of about 24,600 mph (about 39,600 kph). Its launch was the start of the mission to deliver the Mars rover, Perseverance. After six-and-a-half months and about 300 million miles (480 million kilometers), the rover will reach Mars and land on the 28-mile-wide Jezero Crater (Feb. 18, 2021). Once the rover reaches Mars, its mission will be to look for signs of ancient life and collect samples of rock and soil. However, the rover could not do all of this important data collection without an energy source to power it. Idaho National Laboratory is playing a major role in powering Perseverance. INL’s Space Nuclear Power and Isotope Technologies Division assembles and tests Radioisotope Power Systems. -
Advanced Space Propulsion
ADVANCED SPACE PROPULSION Robert H. Frisbee, Ph.D. Jet Propulsion Laboratory California Institute of Technology Pasadena California Transportation Beyond 2000: Engineering Design for the Future September 26-28, 1995 693 ABSTRACT This presentation describes a number of advanced space propulsion technologies with the potential for meeting the need for dramatic reductions in the cost of access to space, and the need for new propulsion capabilities to enable bold new space exploration (and, ultimately, space exploitation) missions of the 21st century. For example, current Earth-to-orbit (e.g., low Earth orbit, LEO) launch costs are extremely high (ca. $10,000/kg); a factor 25 reduction (to ca. $400/kg) will be needed to produce the dramatic increases in space activities in both the civilian and overnment sectors identified in the Commercial Space Transportation Study (CSTS). imilarly, in the area of space exploration, all of the relatively "easy" missions (e.g., robotic flybys, inner solar system orbiters and landers; and piloted short-duration Lunar missions) have been done. Ambitious missions of the next century (e.g., robotic outer-planet orbiters/probes, landers, rovers, sample returns; and piloted long-duration Lunar and Mars missions) will require major improvements in propulsion capability. In some cases, advanced propulsion can enable a mission by making it faster or more affordable, and in some cases, by directly enabling the mission (e.g., interstellar missions). As a general rule, advanced propulsion systems are attractive because of their low operating costs (e.g., higher specific impulse, Isp) and typically show the most benefit for relatively "big" missions (i.e., missions with large payloads or &V, or a large overall mission model). -

Space Elevators: a Feasible Solution for Sending People and Goods Into Space More Cost Effectively
International Journal of Engineering Research and General Science Volume 3, Issue 5, September-October, 2015 ISSN 2091-2730 Space Elevators: A Feasible Solution for Sending People and Goods into Space More Cost Effectively Rupesh Aggarwal1, Pavleen Singh Bali2, Pranay Kami3, A.K. Raghav4 1Teaching Assistant, Department of Aerospace Engg. Amity University Gurgaon, Haryana, India 2Research Associate, Department of E & C Engg. Amity University Gurgaon, Haryana, India 3UG, Department of Aerospace Engg., Amity University Gurgaon, Haryana, India 4M.Tech. IISc Bangalore, Phd. IIT Delhi, Director- IR&D, Amity University Haryana, India Abstract— The Present study focuses on the fascinating concept of Space Elevators. Object of this study is to get introduced with every aspect in Designing, Working & Construction of Space Elevators. It‟s a concept in which tether is used to uplift any type of cargo or personnel from Earth surface to an orbit in space. Such invention not only becomes the new path for heavy loads to get into space but also becomes a cheap one. Also from the top of it, loads can be launch in any desired direction. By this not only the cost of the launch through rocket gets reduced but also the personnel handling this launch i.e. reduction of human error too. Perfect suitable material for such operation is Carbon Nano-tube which hundred times stronger and ten times lighter then Steel. In coming 50 years, it might be possible that many space elevators are ready to launch the spacecraft in space. Its application is not just only limited to the launching but also it can help in carrying heavy payloads to International Space Stations. -

However, little is known yet about the accuracy and relevance of web-based information. In this study, we use 4,485 German firms from the Mannheim Innovation Panel (MIP) 2019 to analyze which website characteristics are related to innovation activities at the firm level. Website characteristics are measured by several text mining methods and are used as features in different Random Forest classification models that are compared against each other. Our results show that the most relevant website characteristics are the website’s language, the number of subpages, and the total text length. Moreover, our website characteristics show a better performance for the prediction of product innovations and innovation expenditures than for the prediction of process innovations.

I was talking within a small but enthusiastic group of attendees at the International Space Development Conference in June 2019. On that stage there was generation "co-inventor" Jerome Pearson, generation "advancing concept" Michael Fitzgerald and generation "excited students" James Torla and Souvik Mukherjee. The "moment" was more than an assembly of young and old. It was also a portrait of the stewards of the Space Elevator revolution -- from Inventor to Developer to Innovators. James was working a college research project on how to get to Mars in 77 days from the Apex Anchor and Souvik (16 years old) was representing his high school from India. -

TECH AND THE FUTURE OF TRANSPORTATION TECH AND THE FUTURE OF TRANSPORTATION: FROM HERE TO THERE BY CHARLES MCLELLAN Articles about technology and the future of transportation rarely used to get far without mentioning jet-packs: a staple of science fiction from the 1920s onwards, the jet pack became a reality in the 1960s in the shape of devices such as the Bell Rocket Belt. But despite many similar efforts, the skies over our cities remain stubbornly free of jet-pack-toting commuters. For a novel form of transport to make a material difference to our lives, several key requirements must be satisfied. Obviously the new technology must work safely, and operate within an appropriate regulatory framework.
