Hubble Space Telescope Observer’S Guide Winter 2021
HUBBLE SPACE TELESCOPE OBSERVER’S GUIDE WINTER 2021 In 2021, the Hubble Space Telescope will celebrate 31 years in operation as a powerful observatory probing the astrophysics of the cosmos from Solar system studies to the high-redshift universe. The high-resolution imaging capability of HST spanning the IR, optical, and UV, coupled with spectroscopic capability will remain invaluable through the middle of the upcoming decade. HST coupled with JWST will enable new innovative science and be will be key for multi-messenger investigations.

CHAeTER 8 INFLUENCE OF PULSARS ON SUPERNOVAE In recent years there has been a great deal of effort to understand in detail the observed light curves of type I1 supernovae. In the standard approach, the observed light curve is to be understood in terms of an initial deposition of thermal energy by the blast wave; and a more gradual input of thermal energy due to radioactive decay of iron-peak elements is invoked to explain the behaviour at later times. The consensus is that the light curves produced by these models are in satisfactory agreement with those observed. In this chapter we discuss the characteristics of the expected light curve, if in addition to the abovementioned sources of energy, there is a continued energy input from an active central pulsar. We argue that in those rare cases when the energy loss rate of the pulsar is comparable to the luminosity of the supernova near light maximum, the light curve will be characterized by an extended plateau phase. The essential reason for this is that the pulsar luminosity is expected to decline over timescales which are much longer than the timescale of, say, radioactive decay. The light curve of the recent supernova in the Large Magellanic Cloud is suggestive of continued energy input from an active pulsar. A detection of strong W,X -ray and 1-ray plerion after the ejecta becomes optically thin will be a clear evidence of the pulsar having powered the light curve.

Solar System Exploration
Theme: Solar System Exploration Cassini, a robotic spacecraft launched in 1997 by NASA, is close enough now to resolve many rings and moons of its destination planet: Saturn. The spacecraft has now closed to within a single Earth-Sun separation from the ringed giant. In November 2003, Cassini snapped the contrast-enhanced color composite pictured above. Many features of Saturn's rings and cloud-tops now show considerable detail. When arriving at Saturn in July 2004, the Cassini orbiter will begin to circle and study the Saturnian system. Several months later, a probe named Huygens will separate and attempt to land on the surface of Titan. Solar System Exploration MAJOR EVENTS IN FY 2005 Deep Impact will launch in December 2004. The spacecraft will release a small (820 lbs.) Impactor directly into the path of comet Tempel 1 in July 2005. The resulting collision is expected to produce a small impact crater on the surface of the comet's nucleus, enabling scientists to investigate the composition of the comet's interior. Onboard the Cassini orbiter is a 703-pound scientific probe called Huygens that will be released in December 2004, beginning a 22-day coast phase toward Titan, Saturn's largest moon; Huygens will reach Titan's surface in January 2005. ESA 2-1 Theme: Solar System Exploration OVERVIEW The exploration of the solar system is a major component of the President's vision of NASA's future. Our cosmic "neighborhood" will first be scouted by robotic trailblazers pursuing answers to key questions about the diverse environments of the planets, comets, asteroids, and other bodies in our solar system. -

Launching a New Era of Exploration Welcome to Langley NASA Langley had a banner year in 2012 as we helped propel the nation toward a new age of air and space. From delivering on missions to creating new technologies and knowledge for space, aviation and science, Langley continued the rich tradition of innovation begun 95 years ago. Langley is providing leading-edge research and game-changing technology innovations for human space exploration. We are testing prototype articles of the Orion crew vehicle to optimize designs and improve landing systems for increased crew survivability. Langley has had a role in private-industry space exploration through agreements with SpaceX, Sierra Nevada Corp. and Boeing to provide engineering expertise, conduct testing and support research. Aerospace and Science With the rest of the world, we held our breath as the Curiosity rover landed on Mars – with Langley’s help. The Langley team performed millions of simulations of the entry, descent and landing phase of the Mars Science Laboratory mission to enable a perfect landing, Langley Center Director Lesa Roe and Mark Sirangelo, corporate and for the first time made temperature and pressure vice president and head of Sierra Nevada Space Systems, with measurements as the spacecraft descended, providing the Dream Chaser Space System model. -
The Distance to the Large Magellanic Cloud
Proceedings Astronomy from 4 perspectives 1. Cosmology The distance to the large magellanic cloud Stefan V¨olker (Jena) In the era of modern cosmology it is necessary to determine the Hubble constant as precise as possible. Therefore it is important to know the distance to the Large Mag- ellanic Cloud (LMC), because this distance forms the fundament of the cosmological distance ladder. The determination of the LMC's distance is an suitable project for highschool students and will be presented in what follows. Calculating the distance to the LMC using the supernova SN 1987 A [1, 2] By combining the angular size α of an object with its absolute size R, one can calculate the distance d (at least for our cosmological neighborhood) using the equation R R d = ≈ (1) tan α α and the approximation d R. In the case of the SN 1987 A students can measure the angular size of the circumstellar ring on the Hubble Space Telescope (HST) image (Figure 1). The absolute size of the ring can be derived from the delay time due to light-travel effects seen in the emission light curve (also Figure 1). Once the supernova exploded, the UV-flash started 1,00 0,75 0,50 intensity (normalized) 0,25 0 0 500 1000 time t/d ESA/Hubble tP1' tP2' Figure 1: left: HST picture of the SN 1987 A; right: emission light curve of the circumstellar [2, 3] propagating and reached the whole ring at the same time, which started emitting immediately. The additional distance x is linked to the delay time by the equation x = c · ∆t = c · (t 0 − t 0 ). -

Planetary Science
Mission Directorate: Science Theme: Planetary Science Theme Overview Planetary Science is a grand human enterprise that seeks to discover the nature and origin of the celestial bodies among which we live, and to explore whether life exists beyond Earth. The scientific imperative for Planetary Science, the quest to understand our origins, is universal. How did we get here? Are we alone? What does the future hold? These overarching questions lead to more focused, fundamental science questions about our solar system: How did the Sun's family of planets, satellites, and minor bodies originate and evolve? What are the characteristics of the solar system that lead to habitable environments? How and where could life begin and evolve in the solar system? What are the characteristics of small bodies and planetary environments and what potential hazards or resources do they hold? To address these science questions, NASA relies on various flight missions, research and analysis (R&A) and technology development. There are seven programs within the Planetary Science Theme: R&A, Lunar Quest, Discovery, New Frontiers, Mars Exploration, Outer Planets, and Technology. R&A supports two operating missions with international partners (Rosetta and Hayabusa), as well as sample curation, data archiving, dissemination and analysis, and Near Earth Object Observations. The Lunar Quest Program consists of small robotic spacecraft missions, Missions of Opportunity, Lunar Science Institute, and R&A. Discovery has two spacecraft in prime mission operations (MESSENGER and Dawn), an instrument operating on an ESA Mars Express mission (ASPERA-3), a mission in its development phase (GRAIL), three Missions of Opportunities (M3, Strofio, and LaRa), and three investigations using re-purposed spacecraft: EPOCh and DIXI hosted on the Deep Impact spacecraft and NExT hosted on the Stardust spacecraft. -
