The Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) contains the only currently operating coronagraph in space that is not trained on the Sun. In an era of extreme-adaptive- optics-fed coronagraphs, and with the possibility of future space-based coronagraphs, we re-evaluate the con- trast performance of the STIS CCD camera. The 50CORON aperture consists of a series of occulting wedges and bars, including the recently commissioned BAR5 occulter. We discuss the latest procedures in obtaining high-contrast imaging of circumstellar disks and faint point sources with STIS. -
The Start of the Manned Space Race by Andrew J
The Start of the Manned Space Race by Andrew J. LePage November 1998 Introduction of Sputnik 1 and 2 in October and November of 1957 changed everything. At the same time NACA and the USAF were studying manned spaceflight (see The Beginnings of The first Sputnik launches were to affect the manned America's Man in Space Program in the October space program in several ways. The impact the 1998 issue of SpaceViews), comparable efforts were launch of Sputnik 1 had on the West led Soviet quietly taking place independently in the Soviet Primer Nikita Khrushchev to exploit space missions Union . As with virtually every other aspect of the for their propaganda value. Development of more Soviet Union's early space program, Chief Designer advanced and spectacular missions like the manned Sergei P. Korolev and his OKB-1 (Experimental satellite program were immediately approved and Design Bureau No. 1) lead the way. All during the placed on the fast track. Also at the insistence of 1950s when Korolev and his colleague, Mikhail K. Khrushchev, Sputnik 2 was launched with a dog on Tikhonravov of NII-4 (Scientific Research Institute board. While thermal control problems marred the No. 4), were pushing their original Earth satellite mission, it did demonstrate that weightlessness would proposal, it also included plans to send probes to the not be a major hazard for a human (see Sputnik 2: Moon and men into orbit. When the satellite The First Animal in Space in the November 1997 proposal was finally adopted by the Soviet issue of SpaceViews). As a result, Korolev scrapped government on January 30, 1956, the lunar probe and his initial, more conservative approach and moved manned satellite projects were also given the green ahead with a much more aggressive plan. -

There is observational evidence of energy injection into the halo from past activity in the nucleus of the Milky Way1–4; however, the origin of this energy (star formation or supermassive-black-hole activity) is uncertain, and the causal connection between nuclear structures and large-scale features has not been established unequivocally. -

The variations in the visual are caused by bolometric flux redistribution in the envelope whilst -10 the bolometric luminosity remains practically constant. The location of R127 in the Hertzsprung-Russell diagram together with the other two known SOor variables of the LMC -B are shown in fig. 8. We note that Walborn classified R127 as an Of or alterna tively as a late WN-type star. This indicates that the star is a late Of star evolving right now towards a WN star. Since we have -6 detected an SOor-type outburst of this star we conclude that this transition is not a smooth one but is instead accompanied '.8 '.6 4.0 3.6 by the occasional ejection of dense envelopes.

Walker, PhD, J.A. Pilkington, BSc, A.N. Winterbottom, H. Hiller, BSc and G.E. Perry, MBE The Table is a chronological list of the 2869 launches of satellites and space vehicles between 1957 and the end of 1986, giving the name and international designation of each satellite and its associated rocket(s), with the date of launch, lifetime (actual or estimated), mass, shape, dimensions and at least one set of orbital parameters. Other fragments associated with a launch, and space vehicles that escape from the Earth's influence, are given without details. Including fragments, more than 17000 satellites appear in the 893 pages of the tabulation, and there is a full Index.

Early observations The science of physical cosmology as it is practiced today had its subject material defined in the years following the Shapley-Curtis debate when it was determined that the universe had a larger scale than the Milky Way galaxy. This was precipitated by observations that established the size and the dynamics of the cosmos that could be explained by Einstein's General Theory of Relativity. -

SOVIET LAUNCH OF SPUTNIK: SPUTNIK-INSPIRED EDUCATIONAL REFORM AND CHANGES IN PRIVATE RETURNS IN AMERICA A Dissertation Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Policy Studies by Hyeonggu Cha December 2015 Accepted by: Dr. Curtis Simon, Committee Chair Dr. Robert Tollison Dr. Holley Ulbrich Dr. Joseph Stewart ABSTRACT On October 4th 1957, the Soviet Union launched the world’s first man-made satellite, Sputnik 1, into an elliptical low Earth orbit. This surprise triggered an arms race between the United States and the Soviet Union, as well as science-oriented educational reform in the U.S. Sputnik sparked changes for the U.S. in military, politics, policies, and education. The launch of Sputnik woke Americans up from complacency came from technology, science, and educational superiority. Educational reform started with emphasizing science and defense education and it was expanded to all levels of education.
