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. -

First Underwater Spectroscopic Scanning Electron Microscopy

South Florida, Tampa, FL; 5Florida Atlantic Univ., Fort Pierce, FL; 6EISC JSC, Houston, TX. Mochii is the world’s smallest production electron microscope, scheduled to travel to the International Space Station (ISS) where it will serve as an ISS National Laboratory (ISSNL) facility upon successful demonstration [1-3]. With high native resolution and chemical energy-dispersive X-ray spectrometer (EDS-enabled “S” model), this tiny coffee-maker sized instrument will provide in-situ engineering analysis and microgravity mission science on-orbit. Scientific inquiries include morphological, textural and chemical characterization of extraterrestrial samples and impact craters produced by exposure to the space environment, as well as samples from living creatures. Mochii will also enhance crew and vehicle safety by rapidly and accurately identifying microscopic mission threats to guide mission decisions, especially in time-critical situations where debris from damaged systems cannot be sent back. Examples of such critical situations are crewmember Luca Parmitano’s waterlogged extra-vehicular activity (EVA) suit in 2013 and the ISS starboard solar alpha rotary joint failure in 2007 where chemical analysis of microscopic particles played a central role in identifying point of failure, source, and problem resolution. A unique test program for space environment operations and equipment testing is the NASA Extreme Environment Mission Operations (NEEMO), an analog flight-like environment implemented 63 ft. -
THE FOUR ARACHNOID GROUPS of VENUS. Kostama, V-P

BOX 3000, FIN-90014, Finland (<[email protected]>). Introduction: A population of 96 arachnoids has some parts of the ridge belt cut the arachnoids. This been found on Venus [1]. These surface structures implies that the arachnoids or the group may have had were first discovered on the Venera 15/16 radar images several evolution phases. and later defined in detail by the Magellan mission [2, 3]. The arachnoids have a peculiar distribution, which is generally different to that of the coronae and particu- larly the novae [4]. The global distribution of arach- noids reflects certain noticeable facts: There is a clear concentration of arachnoid features in the northern hemisphere as 65,6 percent (63 feat.) of the features is located there, while only 34,4 percent (33 feat.) of the population is located in the southern hemisphere [5]. In addition, the arachnoids form four large groups which include roughly 25 % of the total population. The arachnoids of Bereghinya and Ganiki Planitia: The arachnoid group of Bereghinya Planitia is by far the largest arachnoid concentration on Venus. The structural composition of the features of the group are generally distinct and the features are connected by a uniform, chain-like pattern of lineaments. Figure 2.
