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. -

Tianwen-1: China's Mars Mission
Tianwen-1: China's Mars Mission drishtiias.com/printpdf/tianwen-1-china-s-mars-mission Why In News China will launch its first Mars Mission - Tianwen-1- in July, 2020. China's previous ‘Yinghuo-1’ Mars mission, which was supported by a Russian spacecraft, had failed after it did not leave the earth's orbit and disintegrated over the Pacific Ocean in 2012. The National Aeronautics and Space Administration (NASA) is also going to launch its own Mars mission in July, the Perseverance which aims to collect Martian samples. Key Points The Tianwen-1 Mission: It will lift off on a Long March 5 rocket, from the Wenchang launch centre. It will carry 13 payloads (seven orbiters and six rovers) that will explore the planet. It is an all-in-one orbiter, lander and rover system. Orbiter: It is a spacecraft designed to orbit a celestial body (astronomical body) without landing on its surface. Lander: It is a strong, lightweight spacecraft structure, consisting of a base and three sides "petals" in the shape of a tetrahedron (pyramid- shaped). It is a protective "shell" that houses the rover and protects it, along with the airbags, from the forces of impact. Rover: It is a planetary surface exploration device designed to move across the solid surface on a planet or other planetary mass celestial bodies. 1/3 Objectives: The mission will be the first to place a ground-penetrating radar on the Martian surface, which will be able to study local geology, as well as rock, ice, and dirt distribution. It will search the martian surface for water, investigate soil characteristics, and study the atmosphere. -

In this page of this document) activity, you will learn about this amazing feat of engineering as you build your own Mars helicopter • Scissors model. Steps 1. The large marshmallow will represent Ingenuity’s fuselage. Ingenuity is fairly small, about 19 inches tall and weighing about 4 pounds, and the fuselage is about the size of a softball. The fuselage contains batteries, sensors, and cameras to power and control Ingenuity’s flight. It is insulated and has heaters to protect the equipment in the cold Martian environment where it can reach -130 oC at night. 2. Insert the four toothpicks into the marshmallow so they come out at angles as shown in Figure 1. The toothpicks represent the four hollow carbon-fiber legs on Ingenuity. Ingenuity’s legs are designed to be lightweight while still supporting the helicopter when it’s on the Martian surface. To take up less space, Ingenuity’s legs are folded while it’s being carried to Mars. / Figure 1. Insert the four toothpicks into the marshmallow to represent Ingenuity's legs. 3. -
