Summer Constellations
Night Sky 101: Summer Constellations The Summer Triangle Photo Credit: Smoky Mountain Astronomical Society The Summer Triangle is made up of three bright stars—Altair, in the constellation Aquila (the eagle), Deneb in Cygnus (the swan), and Vega Lyra (the lyre, or harp). Also called “The Northern Cross” or “The Backbone of the Milky Way,” Cygnus is a horizontal cross of five bright stars. In very dark skies, Cygnus helps viewers find the Milky Way. Albireo, the last star in Cygnus’s tail, is actually made up of two stars (a binary star). The separate stars can be seen with a 30 power telescope. The Ring Nebula, part of the constellation Lyra, can also be seen with this magnification. In Japanese mythology, Vega, the celestial princess and goddess, fell in love Altair. Her father did not approve of Altair, since he was a mortal. They were forbidden from seeing each other. The two lovers were placed in the sky, where they were separated by the Celestial River, repre- sented by the Milky Way. According to the legend, once a year, a bridge of magpies form, rep- resented by Cygnus, to reunite the lovers. Photo credit: Unknown Scorpius Also called Scorpio, Scorpius is one of the 12 Zodiac constellations, which are used in reading horoscopes. Scorpius represents those born during October 23 to November 21. Scorpio is easy to spot in the summer sky. It is made up of a long string bright stars, which are visible in most lights, especially Antares, because of its distinctly red color. Antares is about 850 times bigger than our sun and is a red giant. -

Spring Constellations Leo
Night Sky 101: Spring Constellations Leo Leo, the lion, is very recognizable by the head of the lion, which looks like a backwards question mark, and is commonly known as “the sickle.” Regulus, Leo’s brightest star, is also easy to pick out in most lights. The constellation is best seen in April and May, but rises after the Spring Equinox in March. Within the constellation, there are several spiral galaxies: M65, M66, M95, and M96. It is possible to fit M65 and M66 into the same view on a low powered telescope. In Greek mythology, Leo was the Nemean lion, who was completely impervious to bronze, steel and any kind of metal. As part of his 12 labors, Hercules was charged to fight the lion and killed him Photo Credit: Starry Night by strangling him. Hercules took the lion’s pelt as a prize and Leo, the lion, was placed in the stars to commemorate their fight. Virgo Virgo is best seen in the late spring and early summer, usually May to June. The bright star Arcturus, in the constellation Boötes, lines up with the Virgo’s brightest star Spica, which makes it easy to find. Within the constellation is the Virgo Galaxy Cluster, which is a conglomerate of thousands of unnamed galaxies. These galaxies are about 65 million light years away, and usually only appear as smudges in a telescope. Virgo, the maiden, is also known as Persephone, or the daughter of the Demeter. Hades, god of the Un- derworld, fell in love with Virgo and took her to the Underworld. -
LUNAR NETWORK TRACKING ARCHITECTURE for LUNAR FLIGHT Shane B
LUNAR NETWORK TRACKING ARCHITECTURE FOR LUNAR FLIGHT Shane B. Robinson∗ A trade study was conducted with the objective of comparing and contrasting the radiometric naviga- tion performance provided by various architectures of lunar-based navigations assets. Architectures considered consist of a compliment of two beacons located on the lunar surface, and two orbiting bea- cons that provide range and range-rate measurements to the user. Configurations of these assets include both coplanar and linked constellations of frozen elliptic orbiters and halo orbiters. Each architecture was studied during the lunar-approach, lunar-orbit, and landing phases of a South Pole lunar sortie mis- sion. Navigation filter performance was evaluated on the basis of filter convergence latency, and the steady state uncertainty in the navigation solution. The sensitivity of the filter solution to Earth-based tracking augmentation and availability of range measurements was also studied. Filter performance was examined during the build up of the lunar-based navigation system by exploring different combi- nations of orbiting and surface-based assets. 1 INTRODUCTION The objective of the work outlined in this document is to conduct a parametric trade intended to evaluate some proposed constellations of moon-orbiting navigation and communication beacons. These orbiting beacons are intended to support the lunar missions of NASA’s Constellation program. This study is sponsored by the flight performance systems integration group at JPL (FPSIG), whose work is funded by the NASA Constellation program office. The work outlined in this report will focus on investigating lunar network aided navigation performance during near lunar phases of baseline missions proposed by the Constellation program. -
Taurus Stars Membership in the Pleiades Open Cluster
Taurus stars membership in the Pleiades open cluster Tadross, A. L., Hanna, M. A., Awadalla, N. S. National Research Institute of Astronomy & Geophysics, NRIAG, 11421 Helwan, Cairo, Egypt ABSTRACT In this paper, we study the characteristics and physical properties of the young open cluster Pleiades using Near Infra-Red, JHK pass bands. Our results have been compared with those found in new optical UBV observations. The membership validity of some variable binary stars, which are Located in Taurus constellation, and their relation with Pleiades cluster have been achieved. 1. INTRODUCTION Pleiades and Hyades are the most famous star clusters in Northern Hemisphere which can be seen by the naked eye in the constellation Taurus the bull. The star cluster surrounding Aldebaran (the eye of the bull) is the Hyades. Pleiades (NGC 1432; M45; Melotte 22; Seven Sisters) is more famous than Hyades because it is more compact cluster and easy seen, higher in the sky (~ 10 degrees from Aldebaran), see Fig 1. Pleiades is located at J (2000) α = 03h: 47m: 24s; δ = +24o: 07’: 12’’; G. long. = 166.642o and G. lat. = -23.457o. The distance to the Pleiades is an important first step in the so- called cosmic distance ladder, a sequence of distance scales for the whole universe. The optical photometry catalogs of Webda and Dais refer to Pleiades as a rich young cluster located at 135-150 pcs away from Earth. In optically observations, Pleiades covers a diameter of about 110 arcmin on the sky; its core and tidal radii are about 33 and 330 arcmins respectively. -
NASA: Issues for Authorization, Appropriations, and Oversight in the 113Th Congress
NASA: Issues for Authorization, Appropriations, and Oversight in the 113th Congress Daniel Morgan Specialist in Science and Technology Policy July 11, 2013 Congressional Research Service 7-5700 www.crs.gov R43144 CRS Report for Congress Prepared for Members and Committees of Congress NASA: Issues for Authorization, Appropriations, and Oversight in the 113th Congress Summary Spaceflight fascinates and inspires many Americans, but in a time of constrained federal budgets, it must compete with a multitude of other national priorities. As the 113th Congress conducts oversight and considers authorization and appropriations legislation for the National Aeronautics and Space Administration (NASA), an overarching question is how NASA should move forward within budget constraints. The National Aeronautics and Space Administration Authorization Act of 2010 (P.L. 111-267) set a new direction for NASA’s human spaceflight programs. For access to low Earth orbit, including the International Space Station (ISS), it confirmed NASA’s plans to develop a commercial space transportation capability for both cargo and astronauts. The first commercial cargo flight for ISS resupply was conducted in May 2012. Pending the planned availability of commercial crew transportation in 2017, NASA is paying Russia to carry U.S. astronauts to and from the ISS on Soyuz spacecraft. Issues for Congress include the cost, schedule, and safety of future commercial crew services, as well as the need for alternatives if commercial providers do not succeed. For human exploration beyond Earth orbit, the 2010 NASA authorization act mandated development of the Orion Multipurpose Crew Vehicle and the Space Launch System (SLS) rocket to launch Orion into space. -

Research Investigates the Brightest Star of 47 Tucanae 10 August 2021, by Tomasz Nowakowski
Research investigates the brightest star of 47 Tucanae 10 August 2021, by Tomasz Nowakowski The brightest star of 47 Tuc at both ultraviolet and optical wavelengths is the so-called "Bright Star" (BS). It is a blue giant star of spectral type B8 III with an effective temperature of some 11,000 K. Moreover, the Bright Star is a post-asymptotic giant branch (post-AGB) star that is moving across the color-magnitude diagram toward the tip of the white- dwarf cooling sequence. Although many studies of the bright star have been conducted, its chemical composition is still poorly understood. Given that the Bright Star represents a unique window into the chemistry of 47 Tuc, a team of astronomers led by William V. Dixon of the Space Telescope Science Institute in Baltimore, Globular cluster 47 Tucanae. Credit: NASA, ESA, and Maryland, investigated this star using the Far the Hubble Heritage (STScI/AURA)-ESA/Hubble Ultraviolet Spectroscopic Explorer (FUSE), the Collaboration.

Margasahayamc aNoise Solutions Inc., #310 605 – 1st Street SW, Calgary, Alberta, Canada T2P 3S9 bFaszer Farquharson & Associates, #304 605 – 1st Street SW, Calgary, Alberta, Canada T2P 3S9 cNASA, John F. Kennedy Space Center, Florida, United States of America 32899 [email protected]; [email protected]; [email protected] Abstract. The crawler transporter (CT) is the world’s second largest known tracked vehicle, weighing 6 million pounds with a length of 131 feet and a width of 113 feet. The Kennedy Space Center (KSC) has two CTs that were designed and built for the Apollo program in the 1960’s, maintained and retrofitted for use in the Space Shuttle program. As a key element of the Space Shuttle ground systems, the crawler transports the entire 12-million-pound stack comprising the orbiter, the mobile launch platform (MLP), the external tank (ET), and the solid rocket boosters (SRB) from the Vehicle Assembly Building (VAB) to the launch pad. This rollout, constituting a 3.5 to 5.0 mile journey at a top speed of 0.9 miles-per-hour, requires over 8 hours to reach either Launch Complex 39A or B. This activity is only a prelude to the spectacle of sound and fury of the Space Shuttle launch to orbit in less than 10 minutes and traveling at orbital velocities of Mach 24. This paper summarizes preliminary results from the Crawler Transporter Sound Attenuation Study, encompassing test and engineering analysis of significant sound sources to measure and record full frequency spectrum and intensity of the various noise sources and to analyze the potential for noise mitigation. -
