Orbital Lifetime Predictions
Orbital LIFETIME PREDICTIONS An ASSESSMENT OF model-based BALLISTIC COEFfiCIENT ESTIMATIONS AND ADJUSTMENT FOR TEMPORAL DRAG co- EFfiCIENT VARIATIONS M.R. HaneVEER MSc Thesis Aerospace Engineering Orbital lifetime predictions An assessment of model-based ballistic coecient estimations and adjustment for temporal drag coecient variations by M.R. Haneveer to obtain the degree of Master of Science at the Delft University of Technology, to be defended publicly on Thursday June 1, 2017 at 14:00 PM. Student number: 4077334 Project duration: September 1, 2016 – June 1, 2017 Thesis committee: Dr. ir. E. N. Doornbos, TU Delft, supervisor Dr. ir. E. J. O. Schrama, TU Delft ir. K. J. Cowan MBA TU Delft An electronic version of this thesis is available at http://repository.tudelft.nl/. Summary Objects in Low Earth Orbit (LEO) experience low levels of drag due to the interaction with the outer layers of Earth’s atmosphere. The atmospheric drag reduces the velocity of the object, resulting in a gradual decrease in altitude. With each decayed kilometer the object enters denser portions of the atmosphere accelerating the orbit decay until eventually the object cannot sustain a stable orbit anymore and either crashes onto Earth’s surface or burns up in its atmosphere. The capability of predicting the time an object stays in orbit, whether that object is space junk or a satellite, allows for an estimate of its orbital lifetime - an estimate satellite op- erators work with to schedule science missions and commercial services, as well as use to prove compliance with international agreements stating no passively controlled object is to orbit in LEO longer than 25 years. -

Centaur performance is described in terms of optimality (pro- pellant usage), flexibility, and airborne computer requirements. Major I-. systems are described narratively with some numerical data given where it may 03 CJ be useful. v, I W INTRODUCT ION The Centaur D1-A launch vehicle continues to be a key element in the Nation's space program. The Atlas/Centaur and Titan/Centaur combinations have boosted into orbit a variety of spacecraft on scientific, lunar, and planetary exploration missions and Earth orbit missions. These versatile, reliable, and accurate space booster systems will contribute to many significant space pro- grams well into the shuttle era. Centaur D1-A is the latest version of the Nation's first high-energy cryogenic launch vehicle. Major improvements in avionics and payload struc- ture have enhanced mission flexibility and mission success reliability. The liquid hydrogen and liquid oxygen propellants and the pressurized stainless steel structure provide a top-performance vehicle. Centaur's primary thrust comes from two Pratt 8, Whitney constant- thrust, turbopump-fed, regeneratively cooled, liquid-fueled rocket engines. Each RL10A-3-3a engine can generate 16 500 lb of thrust, for a total thrust of 33 000 lb. -
FASTSAT a Mini-Satellite Mission…..A Way Ahead”
Proposed Abstract: Under the combined Category and Title: “FASTSAT a Mini-Satellite Mission…..A Way Ahead” Authors: Mark E. Boudreaux, Joseph Casas, Timothy A. Smith The Fast Affordable Science and Technology Spacecraft (FASTSAT) is a mini-satellite weighing less than 150 kg. FASTSAT was developed as government-industry collaborative research and development flight project targeting rapid access to space to provide an alternative, low cost platform for a variety of scientific, research, and technology payloads. The initial spacecraft was designed to carry six instruments and launch as a secondary “rideshare” payload. This design approach greatly reduced overall mission costs while maximizing the on-board payload accommodations. FASTSAT was designed from the ground up to meet a challenging short schedule using modular components with a flexible, configurable layout to enable a broad range of payloads at a lower cost and shorter timeline than scaling down a more complex spacecraft. The integrated spacecraft along with its payloads were readied for launch 15 months from authority to proceed. As an ESPA-class spacecraft, FASTSAT is compatible with many different launch vehicles, including Minotaur I, Minotaur IV, Delta IV, Atlas V, Pegasus, Falcon 1/1e, and Falcon 9. These vehicles offer an array of options for launch sites and provide for a variety of rideshare possibilities.

Distribution of Nitrifying Bacteria Under Fluctuating Environmental Conditions
Distribution of Nitrifying Bacteria Under Fluctuating Environmental Conditions Joseph M. Battistelli Stratford, Connecticut B.S., Rutgers, the State Universi ty of New Jersey, New Brunswick Campus, 2002 A Dissertation presented to the Graduate Faculty of the University of Virginia in Candidacy for the Degree of Doctor of Philosophy Department of Environmental Sciences University of Virginia December, 2012 ii Abstract Engineered systems that mimic tidal wetlands are ideal for point-of-source treatment of wastewater due to their low energy requirements and small physical footprint. In this study, vertical columns were constructed to mimic the flood-and-drain cycles of tidal wetland treatment systems (TWTS) in order to study how variations in the frequency and duration of flooding affect the efficiency of microbially-mediated nitrogen + removal from synthetic wastewater (containing whey protein and NH 4 ). Altering the frequency of flooding, which determines the temporal juxtaposition of aerobic and anaerobic conditions in the reactor, had a significant effect on overall nitrogen removal; + columns more frequent cycling were very efficient at converting the NH4 in the feed to - - NO 3 . At a flooding frequency of 8-cycles per day, NO 3 began to disappear from the systems in both High- and Low - N treatments. The longer flooding duration appeared to increased anaerobiosis and allowed denitrification to proceed more effectively, while allowing nitrification to proceed when oxygen was available. Analysis of depth profiles of abundance revealed distinct differences between the tidal and trickling systems abundance profiles. Overall, these results demonstrate a tight coupling of environmental conditions with the abundance of ammonium oxidizing bacteria and suggest several experimental modifications, such variable tidal cycles, could be implemented to enhance the functioning of TWTS. -
Space Missions for Exoplanet
Space missions for exoplanet January 3, 2020 Source: The Hindu Manifest pedagogy: As a part of science & technology and geography, questions related to space have been asked both at prelims and mains stage. Finding life in other celestial bodies had always been a human curiosity. Origin of the solar system, exoplanets as prospective resources zone, finding life etc are key objectives of NASA and other space programs. In news: European Space Agency (ESA) has launched CHEOPS exoplanet mission Placing it in syllabus: Exoplanet space missions Static dimensions: What are exoplanets? Current dimensions: Exoplanet missions by NASA Exoplanet missions by ESA and CHEOPS mission Content: What are Exoplanets? The worlds orbiting other stars are called “exoplanets”. They vary in sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth. They can be hot enough to boil metal or locked in deep freeze. They can orbit two suns at once. Some exoplanets are sunless, wandering through the galaxy in permanent darkness. The first exoplanet invented was 51 Pegasi b, a “hot Jupiter” in 1995 which is 50 light-years away that is locked in a four-day orbit around its star. ((The discoverers Didier Queloz and Michel Mayor of 51 Pegasi b shared the 2019 Nobel Prize in Physics for their breakthrough finding)). And a system of three “pulsar planets” had been detected, beginning in 1992. The circumstellar habitable zone (CHZ) also called the Goldilocks zone is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. -
