Onboard Determination of Vehicle Glide Capability for Shuttle Abort Flight Managment (Safm)
Source of Acquisition NASA Johnson Space Center ONBOARD DETERMINATION OF VEHICLE GLIDE CAPABILITY FOR SHUTTLE ABORT FLIGHT MANAGMENT (SAFM) Mark Jackson, Timothy Straube, Thomas Fill, Scott Nemeth, When one or more main engines fail during ascent, the flight crew of the Space Shuttle must make several critical decisions and accurately perform a series of abort procedures. One of the most important decisions for many aborts is the selection ofa landing site. Several factors influence the ability to reach a landing site, including the spacecraft point of atmospheric entry, the energy state at atmospheric entry, the vehicle glide capability from that energy state, and whether one or more suitable landing sites are within the glide capability. Energy assessment is further complicated by the fact that phugoid oscillations in total energy influence glide capability. Once the glide capability is known, the crew must select the "best" site option based upon glide capability and landing site conditions and facilities. Since most of these factors cannot currently be assessed by the crew in flight, extensive planning is required prior to each mission to script a variety of procedures based upon spacecraft velocity at the point of engine failure (or failures). The results of this pre flight planning are expressed in tables and diagrams on mission-specific cockpit checklists. Crew checklist procedures involve leafing through several pages of instructions and navigating a decision tree for site selection and flight procedures - all during a time critical abort situation. With the advent of the Cockpit Avionics Upgrade (CAU), the Shuttle will have increased on-board computational power to help alleviate crew workload during aborts and provide valuable situational awareness during nominal operations. -

Soviet Steps Toward Permanent Human Presence in Space
SALYUT: Soviet Steps Toward Permanent Human Presence in Space December 1983 NTIS order #PB84-181437 Recommended Citation: SALYUT: Soviet Steps Toward Permanent Human Presence in Space–A Technical Mere- orandum (Washington, D.

Library of Congress Catalog Card Number 83-600624 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 Foreword As the other major spacefaring nation, the Soviet Union is a subject of interest to the American people and Congress in their deliberations concerning the future of U.S. space activities. In the course of an assessment of Civilian Space Stations, the Office of Technology Assessment (OTA) has undertaken a study of the presence of Soviets in space and their Salyut space stations, in order to provide Congress with an informed view of Soviet capabilities and intentions. The major element in this technical memorandum was a workshop held at OTA in December 1982: it was the first occasion when a significant number of experts in this area of Soviet space activities had met for extended unclassified discussion. As a result of the workshop, OTA prepared this technical memorandum, “Salyut: Soviet Steps Toward Permanent Human Presence in Space. ” It has been reviewed extensively by workshop participants and others familiar with Soviet space activities. Also in December 1982, OTA wrote to the U. S. S. R.’s Ambassador to the United States Anatoliy Dobrynin, requesting any information concerning present and future Soviet space activities that the Soviet Union judged could be of value to the OTA assess- ment of civilian space stations. -

Mars Exploration - a Story Fifty Years Long Giuseppe Pezzella and Antonio Viviani
Chapter Introductory Chapter: Mars Exploration - A Story Fifty Years Long Giuseppe Pezzella and Antonio Viviani 1. Introduction Mars has been a goal of exploration programs of the most important space agencies all over the world for decades. It is, in fact, the most investigated celestial body of the Solar System. Mars robotic exploration began in the 1960s of the twentieth century by means of several space probes sent by the United States (US) and the Soviet Union (USSR). In the recent past, also European, Japanese, and Indian spacecrafts reached Mars; while other countries, such as China and the United Arab Emirates, aim to send spacecraft toward the red planet in the next future. 1.1 Exploration aims The high number of mission explorations to Mars clearly points out the impor- tance of Mars within the Solar System. Thus, the question is: “Why this great interest in Mars exploration?” The interest in Mars is due to several practical, scientific, and strategic reasons. In the practical sense, Mars is the most accessible planet in the Solar System [1]. It is the second closest planet to Earth, besides Venus, averaging about 360 million kilometers apart between the furthest and closest points in its orbit. Earth and Mars feature great similarities. For instance, both planets rotate on an axis with quite the same rotation velocity and tilt angle. The length of a day on Earth is 24 h, while slightly longer on Mars at 24 h and 37 min. The tilt of Earth axis is 23.5 deg, and Mars tilts slightly more at 25.2 deg [2]. -

It is expected to land on the Red Planet on Nov. 26, 2018. InSight is a mission to Mars, but it is more than a Mars mission. It will help scientists understand the formation and early evolution of all rocky planets, including Earth. A technology demonstration called Mars Cube One (MarCO) will share the launch with InSight and fly separately to Mars. Six Ways InSight Is Different NASA has a long and successful track record at Mars. Since 1965, it has flown by, orbited, landed and roved across the surface of the Red Planet. None of that has been easy. Only about 40 percent of the missions ever sent to Mars by any space agency have been successful. The planet’s thin atmosphere makes landing a challenge; its extreme temperature swings make it difficult to operate on the surface. But if a spacecraft survives the trip, there’s a bounty of science to be collected.
