An Ethnography of the Spring Festival
IMAGINING CHINA IN THE ERA OF GLOBAL CONSUMERISM AND LOCAL CONSCIOUSNESS: MEDIA, MOBILITY, AND THE SPRING FESTIVAL A dissertation presented to the faculty of the College of Communication of Ohio University In partial fulfillment of the requirements for the degree Doctor of Philosophy Li Ren June 2003 This dissertation entitled IMAGINING CHINA IN THE ERA OF GLOBAL CONSUMERISM AND LOCAL CONSCIOUSNESS: MEDIA, MOBILITY AND THE SPRING FESTIVAL BY LI REN has been approved by the School of Interpersonal Communication and the College of Communication by Arvind Singhal Professor of Interpersonal Communication Timothy A. Simpson Professor of Interpersonal Communication Kathy Krendl Dean, College of Communication REN, LI. Ph.D. June 2003. Interpersonal Communication Imagining China in the Era of Global Consumerism and Local Consciousness: Media, Mobility, and the Spring Festival. (260 pp.) Co-directors of Dissertation: Arvind Singhal and Timothy A. Simpson Using the Spring Festival (the Chinese New Year) as a springboard for fieldwork and discussion, this dissertation explores the rise of electronic media and mobility in contemporary China and their effect on modern Chinese subjectivity, especially, the collective imagination of Chinese people. Informed by cultural studies and ethnographic methods, this research project consisted of 14 in-depth interviews with residents in Chengdu, China, ethnographic participatory observation of local festival activities, and analysis of media events, artifacts, documents, and online communication. The dissertation argues that “cultural China,” an officially-endorsed concept that has transformed a national entity into a borderless cultural entity, is the most conspicuous and powerful public imagery produced and circulated during the 2001 Spring Festival. As a work of collective imagination, cultural China creates a complex and contested space in which the Chinese Party-state, the global consumer culture, and individuals and local communities seek to gain their own ground with various strategies and tactics. -

On Parker Solar Probe, NASA Leaves the Driving to Aerojet Rocketdyne
On Parker Solar Probe, NASA Leaves the Driving to Aerojet Rocketdyne August 12, 2018 KENNEDY SPACE CENTER, Fla., Aug. 12, 2018 (GLOBE NEWSWIRE) -- With a big assist from Aerojet Rocketdyne, NASA’s Parker Solar Probe is now on its way to humankind’s closest encounter ever with a star – in this case our solar system’s sun. Parker Solar Probe NASA image Aerojet Rocketdyne provided the full propulsion system on NASA’s Parker Solar Probe, which will venture eight times closer to the Sun than the previous record holderCredit: NASA/Johns Hopkins APL In addition to the RS-68A main engines for the United Launch Alliance Delta IV Heavy rocket that launched the Parker Probe into space, Aerojet Rocketdyne also supplied the RL10B-2 second stage engine and 12 MR-106 reaction control thrusters on the Delta Cryogenic Second Stage, as well as the full propulsion system on the Parker Solar Probe. The nearly 7-year journey will bring the probe to within 6.2 million kilometers of the Sun’s surface. That’s well within the orbit of the Sun’s nearest planet, Mercury, and eight times closer than the previous record holder, the U.S.-German Helios B probe, which made its closest approach in 1976. “Surviving a years-long journey to the corona of the Sun while operating in autonomous mode requires an incredibly high level of reliability,” said Aerojet Rocketdyne CEO and President Eileen Drake. “Aerojet Rocketdyne propulsion plays a critical role in all aspects of the Parker Solar Probe mission, from launch on the Delta IV, to the probe’s safe cruise through space and approach of the Sun’s atmosphere.” The Parker Solar Probe ultimately will dip into the Sun’s corona, carrying instruments to observe and measure the movement and interaction of phenomena including electric and magnetic fields, energetic particles and solar wind. -

It was observed that in encounter 2 of NASA’s Parker Solar Probe mission there was a large amount of radio activity, and in particular a noise storm of frequent, small type III bursts from 31st March to 6th April 2019. Our aim is to investigate the source of these small and frequent bursts. -

IAF SPACE PROPULSION SYMPOSIUM (C4) New Missions Enabled by New Propulsion Technology and Systems (6)
70th International Astronautical Congress 2019 Paper ID: 54982 oral IAF SPACE PROPULSION SYMPOSIUM (C4) New Missions Enabled by New Propulsion Technology and Systems (6) Author: Mr. Steven Vernon Johns Hopkins University Applied Physics Laboratory, United States, [email protected] LAUNCH SYSTEM SOLUTIONS FOR INTERSTELLAR TRAVEL Abstract Building on the experience gained from several successful high launch energy NASA exploration mis- sions, a NASA funded study focused on developing a launch system capable of Interstellar travel in the near term is discussed. The NASA funded Interstellar Probe study managed by Johns Hopkins applied Physics Lab focused on the development a set of launch vehicle and upper stage system solution concepts. The configurations discussed are designed to achieve launch energies significantly above the two previous record setting missions, New Horizons and Parker Solar Probe. The launch system configurations dis- cussed will document of several the very high launch energy solutions explored. With the advent of the NASA Space Launch System (SLS) and its significant lift mass capabilities, coupled to the significant volume available inside the fairing, the SLS system is demonstrated to be particularly well suited to the stacking of one or more upper stages in order to improve and minimize space travel mission durations. The system solutions presented are designed to increase the ultimate launch energies, by a factor of 2-3 times above those achieved for the New Horizons (wet mass = 478 kg, C3 =157.75 km**2/s**2) and Parker Solar Probe (wet mass = 643 kg, C3=154 km**2/s**2) missions. While these two separated Spacecraft launch energy examples were significant engineering achievements, incorporating the Atlas V, 551 and Delta IV Heavy launch systems with unique upper stages, the SLS lift capability configurations presented will be coupled to several Oberth maneuvers and passive and gravity assist trajectories studied. -
