United States Government Accountability Office Report to Congressional Committees March 2016 NASA Assessments of Major Projects GAO-16-309SP March 2016 NASA Assessments of Major Projects Highlights of GAO-16-309SP, a report to congressional committees Why GAO Did This Study What GAO Found This report provides GAO’s annual The cost and schedule performance of the National Aeronautics and Space snapshot of how well NASA is planning Administration’s (NASA) portfolio of major projects has improved over the past 5 and executing its major acquisition years, and most current projects are adhering to their committed cost and projects. In March 2015, GAO found schedule baselines. Over the last 2 years, eight projects in the portfolio that projects continued a general established cost and schedule baselines. As the figure below shows, as the positive trend of limiting cost and average age of the portfolio has decreased, the cost performance of the portfolio schedule growth, maturing has improved, because new projects are less likely to have experienced cost technologies, and stabilizing designs, growth. but that NASA faced several challenges that could affect its ability to Development Cost Performance of NASA’s Major Project Portfolio Has Improved as Average effectively manage its portfolio. Project Age Has Decreased The explanatory statement of the House Committee on Appropriations accompanying the Omnibus Appropriations Act, 2009 included a provision for GAO to prepare project status reports on selected large-scale NASA programs, projects, and activities. This is GAO’s eighth annual assessment of NASA’s major projects. This report describes (1) the cost and schedule performance of NASA’s portfolio of major projects, (2) the maturity of technologies and stability of project designs at key milestones, and (3) NASA’s progress in implementing Note: GAO presents cost and schedule growth both including and excluding JWST because the initiatives to manage acquisition risk magnitude of JWST’s cost growth has historically masked the performance of the rest of the portfolio. -

High-Temporal-Resolution Water Level and Storage Change Data Sets for Lakes on the Tibetan Plateau During 2000–2017 Using Mult

High-temporal-resolution water level and storage change data sets for lakes on the Tibetan Plateau during 2000–2017 using multiple altimetric missions and Landsat-derived lake shoreline positions Xingdong Li1, Di Long1, Qi Huang1, Pengfei Han1, Fanyu Zhao1, and Yoshihide Wada2 1State Key Laboratory of Hydroscience and Engineering, Department of Hydraulic Engineering, Tsinghua University, Beijing, China 2International Institute for Applied Systems Analysis (IIASA), 2361 Laxenburg, Austria Correspondence: Di Long ([email protected]) Received: 21 February 2019 – Discussion started: 15 March 2019 Revised: 4 September 2019 – Accepted: 22 September 2019 – Published: 28 October 2019 Abstract. The Tibetan Plateau (TP), known as Asia’s water tower, is quite sensitive to climate change, which is reflected by changes in hydrologic state variables such as lake water storage. Given the extremely limited ground observations on the TP due to the harsh environment and complex terrain, we exploited multiple altimetric mis- sions and Landsat satellite data to create high-temporal-resolution lake water level and storage change time series at weekly to monthly timescales for 52 large lakes (50 lakes larger than 150 km2 and 2 lakes larger than 100 km2) on the TP during 2000–2017. The data sets are available online at https://doi.org/10.1594/PANGAEA.898411 (Li et al., 2019). With Landsat archives and altimetry data, we developed water levels from lake shoreline posi- tions (i.e., Landsat-derived water levels) that cover the study period and serve as an ideal reference for merging multisource lake water levels with systematic biases being removed. -
Report by the ESA–ESO Working Group on Extra-Solar Planets
Report by the ESA–ESO Working Group on Extra-Solar Planets 4 March 2005 Summary Various techniques are being used to search for extra-solar planetary signatures, including accurate measurement of radial velocity and positional (astrometric) dis- placements, gravitational microlensing, and photometric transits. Planned space experiments promise a considerable increase in the detections and statistical know- ledge arising especially from transit and astrometric measurements over the years 2005–15, with some hundreds of terrestrial-type planets expected from transit mea- surements, and many thousands of Jupiter-mass planets expected from astrometric measurements. Beyond 2015, very ambitious space (Darwin/TPF) and ground (OWL) experiments are targeting direct detection of nearby Earth-mass planets in the habitable zone and the measurement of their spectral characteristics. Beyond these, ‘Life Finder’ (aiming to produce confirmatory evidence of the presence of life) and ‘Earth Imager’ (some massive interferometric array providing resolved images of a distant Earth) arXiv:astro-ph/0506163v1 8 Jun 2005 appear as distant visions. This report, to ESA and ESO, summarises the direction of exo-planet research that can be expected over the next 10 years or so, identifies the roles of the major facilities of the two organisations in the field, and concludes with some recommendations which may assist development of the field. The report has been compiled by the Working Group members and experts (page iii) over the period June–December 2004. Introduction & Background Following an agreement to cooperate on science planning issues, the executives of the European Southern Observatory (ESO) and the European Space Agency (ESA) Science Programme and representatives of their science advisory structures have met to share information and to identify potential synergies within their future projects. -

Spacex Sends Its Latest Rocket to Space with Something Unusual Inside by Associated Press, Adapted by Newsela Staff on 02.16.18 Word Count 652 Level 820L
SpaceX sends its latest rocket to space with something unusual inside By Associated Press, adapted by Newsela staff on 02.16.18 Word Count 652 Level 820L This image from video provided by SpaceX shows owner Elon Musk's red Tesla sports car which was launched into space during the first test flight of the Falcon Heavy rocket on February 6, 2018. Photo by: SpaceX via AP CAPE CANAVERAL, Florida — The world's first space sports car is heading well beyond Mars. The red electric Tesla Roadster is aboard the brand new Falcon Heavy rocket. The company SpaceX launched the Heavy for its first test flight on February 6. Elon Musk runs the company SpaceX and the car company Tesla. Musk owns the sports car now flying through space. Musk, astronauts and many others cheered the successful launch from Florida. The Heavy is now the most powerful rocket flying these days. The space Roadster is now the fastest car ever. It is on a journey that will take it all the way to the asteroid belt between Mars and Jupiter. The asteroid belt is where unusually shaped space rocks and small planets orbit. This article is available at 5 reading levels at https://newsela.com. 1 Roadster Has Many Miles To Go Musk said the firing of the rocket's final booster engine put his car on a more distant flight than expected. It should go beyond Mars. It might almost reach the dwarf planet Ceres in the asteroid belt. Inside the car is a mannequin wearing a SpaceX spacesuit.
