Space Missions for Exoplanet
Space missions for exoplanet January 3, 2020 Source: The Hindu Manifest pedagogy: As a part of science & technology and geography, questions related to space have been asked both at prelims and mains stage. Finding life in other celestial bodies had always been a human curiosity. Origin of the solar system, exoplanets as prospective resources zone, finding life etc are key objectives of NASA and other space programs. In news: European Space Agency (ESA) has launched CHEOPS exoplanet mission Placing it in syllabus: Exoplanet space missions Static dimensions: What are exoplanets? Current dimensions: Exoplanet missions by NASA Exoplanet missions by ESA and CHEOPS mission Content: What are Exoplanets? The worlds orbiting other stars are called “exoplanets”. They vary in sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth. They can be hot enough to boil metal or locked in deep freeze. They can orbit two suns at once. Some exoplanets are sunless, wandering through the galaxy in permanent darkness. The first exoplanet invented was 51 Pegasi b, a “hot Jupiter” in 1995 which is 50 light-years away that is locked in a four-day orbit around its star. ((The discoverers Didier Queloz and Michel Mayor of 51 Pegasi b shared the 2019 Nobel Prize in Physics for their breakthrough finding)). And a system of three “pulsar planets” had been detected, beginning in 1992. The circumstellar habitable zone (CHZ) also called the Goldilocks zone is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. -
2. Going to Mars
aMARTE A MARS ROADMAP FOR TRAVEL AND EXPLORATION Final Report International Space University Space Studies Program 2016 © International Space University. All Rights Reserved. The 2016 Space Studies Program of the International Space University (ISU) was hosted by the Technion – Israel Institute of Technology in Haifa, Israel. aMARTE has been selected as the name representing the Mars Team Project. This choice was motivated by the dual meaning the term conveys. aMARTE first stands for A Mars Roadmap for Travel and Exploration, the official label the team has adopted for the project. Alternatively, aMARTE can be interpreted from its Spanish roots "amarte," meaning "to love," or can also be viewed as "a Marte," meaning "going to Mars." This play on words represents the mission and spirit of the team, which is to put together a roadmap including various disciplines for a human mission to Mars and demonstrate a profound commitment to Mars exploration. The aMARTE title logo was developed based on sections of the astrological symbols for Earth and Mars. The blue symbol under the team's name represents Earth, and the orange arrow symbol is reminiscent of the characteristic color of Mars. The arrow also serves as an invitation to go beyond the Earth and explore our neighboring planet.

Exoplanetary Transits As Seen by Gaia
Highlights of Spanish Astrophysics VII, Proceedings of the X Scientific Meeting of the Spanish Astronomical Society held on July 9 - 13, 2012, in Valencia, Spain. J. C. Guirado, L.M. Lara, V. Quilis, and J. Gorgas (eds.) Exoplanetary transits as seen by Gaia H. Voss1;2, C. Jordi1;2;3, C. Fabricius1;2, J. M. Carrasco1;2, E. Masana1;2, and X. Luri1;2;3 1 IEEC: Institut d'Estudis Espacials de Catalunya 2 ICC-UB: Institut de Ci`encesdel Cosmos de la Universitat de Barcelona 3 UB: Departament d'Astronomia i Meteorologia, Universitat de Barcelona Abstract The ESA cornerstone mission Gaia will be launched in 2013 to begin a scan of about one billion sources in the Milky Way and beyond. During the mission time of 5 years (+ one year extension) repeated astrometric, photometric and spectroscopic observations of the entire sky down to magnitude 20 will be recorded. Therefore, Gaia as an All-Sky survey has enormous potential for discovery in almost all fields of astronomy and astrophysics. Thus, 50 to 200 epoch observations will be collected during the mission for about 1 billion sources. Gaia will also be a nearly unbiased survey for transiting extrasolar planets. Based on latest detection probabilities derived from the very successful NASA Kepler mis- sion, our knowledge about the expected photometric precision of Gaia in the white-light G band and the implications due to the Gaia scanning law, we have analysed how many transiting exoplanets candidates Gaia will be able to detect. We include the entire range of stellar types in the parameter space for our analysis as potential host stars, as they will be observed by Gaia. -
Mars Sample Return Using Commercial Capabilities: Mission Architecture Overview
IEEE Aerospace Conference Yellowstone Conference Center in Big Sky Montana Session: 2.06 Future Missions & Enabling Technologies for In Situ Exploration, Sample Returns Sat 3/1/2014 Sat 3/8/2014 http://www.aeroconf.org/ Authors: Andrew A. Gonzales, NASA Ames Research Center Lawrence G. Lemke, NASA Ames Research Center Carol R. Stoker , NASA Ames Research Center Nicolas T. Faber, Stinger Ghaffarian Technologies Margaret S. Race, SETI Institute Mars Sample Return Using Commercial Capabilities: Mission Architecture Overview Mars Sample Return (MSR) is the highest priority science mission for the next decade as recommended by the recent Decadal Survey of Planetary Science. This paper presents an overview of a feasibility study for an MSR mission. The objective of the study was to determine whether emerging commercial capabilities can be used to reduce the number of mission systems and launches required to return the samples, with the goal of reducing mission cost. We report the feasibility of a complete and closed MSR mission design using the following scenario that covers three synodic launch opportunities, beginning with the 2022 opportunity: A Falcon Heavy injects a SpaceX Red Dragon capsule and trunk onto a Trans Mars Injection (TMI) trajectory. The capsule is modified to carry all the hardware needed to return samples collected on Mars including a Mars Ascent Vehicle (MAV), an Earth Return Vehicle (ERV), and hardware to transfer a sample collected in a previously landed rover mission to the ERV. The Red Dragon descends to land on the surface of Mars using Super Sonic Retro Propulsion (SSRP). After previously collected samples are transferred to the ERV, the single-stage MAV launches the ERV from the surface of Mars. -
1 HOLD for RELEASE UNTIL PRESENTED by WITNESS March
HOLD FOR RELEASE UNTIL PRESENTED BY WITNESS March 13, 2019 Statement of James F. Bridenstine Administrator National Aeronautics and Space Administration before the Committee on Commerce, Science, and Transportation United States Senate Mr. Chairman and Members of the Committee, I am very pleased to appear before you today. NASA is proud to be at the forefront of a global effort to advance humanity’s future in space, leading the world while expanding on our Nation’s great capacity for exploration and innovation. This is a role the Agency has played for over 60 years, leveraging the talent and hard work of America’s skilled Government and aerospace industry workforce to push the boundaries of science, exploration, and technology development to achieve bold goals in the aviation and space arenas. Now, pursuant to Space Policy Directive-1 (and consistent with the NASA Transition Authorization Act of 2017), NASA is pursuing “an innovative and sustainable program of exploration with commercial and international partners to enable human expansion across the solar system and to bring back to Earth new knowledge and opportunities.” We are working on a sustainable campaign of exploration, transitioning the International Space Station (ISS), returning humans to the surface of the Moon and lunar orbit, where we will build the systems, deep space infrastructure, and operational capabilities to expand human presence beyond the Earth-Moon system, eventually embarking on human missions to Mars and other destinations. Since its inception, NASA’s historic and enduring purpose has been aligned to four major strategic thrusts – Discover, Explore, Develop, and Enable. These correspond to our missions of scientific discovery of the natural phenomena of the Earth, of other worlds, and of the cosmos as a whole. -
The New Generation Planetary Population Synthesis (NGPPS). II
Astronomy & Astrophysics manuscript no. pop c ESO 2020 July 14, 2020 The New Generation Planetary Population Synthesis (NGPPS) II. Planetary population of solar-like stars and overview of statistical results? Alexandre Emsenhuber1; 2, Christoph Mordasini2, Remo Burn2, Yann Alibert2, Willy Benz2, and Erik Asphaug1 1 Lunar and Planetary Laboratory, University of Arizona, 1629 E. University Blvd., Tucson, AZ 85721, USA e-mail: [email protected] 2 Physikalisches Institut, Universität Bern, Gesselschaftsstrasse 6, 3012 Bern, Switzerland Received DD MMM YYYY / Accepted DD MMM YYYY ABSTRACT Context. Planetary formation and evolution is a combination of multiple processes that are interlinked. These processes are not known in detail and many uncertainties remain. Constraining the formation and evolution mechanisms observationally requires statistical comparison to a large diversity of planetary systems. Aims. We want to understand the global observable consequences of different physical processes (accretion, migration, and interac- tions) and initial properties (such as disc masses and metallicities) on the demographics of the planetary population. We also want to study the convergence of our scheme with respect to one initial condition, the initial number of planetary embryo in each disc. Methods. We select distributions of initial conditions that are representative of known protoplanetary discs. Then, we use the Gener- ation III Bern model to perform planetary population synthesis. We synthesise five populations with each a different initial number of Moon-mass embryos per disc: 1, 10, 20, 50, and 100. The last is our nominal planetary population consisting of 1000 stars (systems) that we use to provide an extensive statistical analysis of the planetary systems around 1 M stars.
