    Astronaut Jim Lovell Q&A Hosted by Professor Brian Cox - Space Lectures

    36:48

    Apollo 13 Astronaut James Lovell talks about his Space Experiences during this Question and Answer session hosted by Physicist Brian Cox at the Space Lectures event in Pontefract.

    Subscribe:

    Captain Lovell was selected as an Astronaut by NASA in September 1962. He has since served as backup pilot for the Gemini 4 flight and backup Commander for the Gemini 9 flight, as well as backup Commander to Neil Armstrong for the Apollo 11 lunar landing mission.

    On December 4, 1965, he and Frank Borman were launched into space on the history-making Gemini 7 mission. The flight lasted 330 hours and 35 minutes and included the first rendezvous of two manned maneuverable spacecraft.

    The Gemini 12 mission, commanded by Lovell with Pilot Edwin Aldrin, began on November 11, 1966. This 4-day, 59-revolution flight brought the Gemini program to a successful close. Lovell served as Command Module Pilot and Navigator on the epic six-day journey of Apollo 8 - man's maiden voyage to the moon - December 21-27, 1968. Apollo 8 was the first manned spacecraft to be lifted into near-earth orbit by a 7-1/2 million pound thrust Saturn V launch vehicle; and Lovell and fellow crewmen, Frank Borman and William A. Anders, became the first humans to leave the Earth's gravitational influence.

    He completed his fourth mission as Spacecraft Commander of the Apollo 13 flight, April 11-17, 1970, and became the first man to journey twice to the moon. Apollo 13 was programmed for ten days. However, the original flight plan was modified en route to the moon due to a failure of the Service Module cryogenic oxygen system. Lovell and fellow crewmen, John L. Swigert and Fred W. Haise, working closely with Houston ground controllers, converted their lunar module Aquarius into an effective lifeboat. Their emergency activation and operation of lunar module systems conserved both electrical power and water in sufficient supply to assure their safety and survival while in space and for the return to earth.

    Interstellar Lecture by Kelvin Long

    1:23:09

    Full Lecture:
    In 2007 Kelvin Long set up to systematically address various aspects of interstellar travel. This included the faster than light warp drives of science fiction, the grand scale world ships required for interstellar colonisation strategies and the initiation of a research study, Project Icarus. The intention along this journey has been to catalyse interstellar studies for the purpose of working towards the creation of a self-fulfilling and optimistic prophesy in space. The near-term goals of this work were to (i) regenerate the interstellar community by the injection of new energy, ideas, and initiatives and (ii) renew design capability for starship skills through educational programs. In this lecture Kelvin will set out the overall strategy, achievements to date and next steps. In particular, an interstellar design competition will be announced as well as the formation of the world's first dedicated interstellar research organization -- The Institute for Interstellar Studies. The creation of a new space company, Stellar Engines Ltd, will also be announced along with its primary goal to connect people with knowledge. This lecture will describe what needs to be done now so that human missions to the stars are feasible by the end of the current century. Kelvin F. Long is an aerospace engineer, physicist, author and Editor of the Journal of the British Interplanetary Society

Etched into their surfaces is a fascinating story -- of fire and ice, of order and upheaval, of great cataclysms and slow change. Volcanism, impact, wind, and water are all common forces that shape these worlds, sometimes in ways familiar to us on Earth, sometimes in ways that amaze us.

    Carl Sagan on Space Travel: A Dandelion Going To Seed

    2:15

    In 1977 Carl Sagan gave the CHRISTMAS LECTURES on space travel. In his final lecture, he spoke about the human race venturing out into space; his words are as relevant now as they were then.
    Day 14 of our advent calendar, A Place Called Space.

    Watch his lectures in full on the Ri Channel:

    In 1977 we had begun to tiptoe into space, and felt on the edge of the Universe, about to dive in. Almost 40 years later, we’ve made great progress and large strides further into space, but in some ways have barely got our feet wet. The words Carl Sagan concluded his Lectures on ‘The planets’ with are as meaningful now as there were then.

    As we look to send people to Mars and then beyond, are we finally realising Sagan’s vision?

    This clip from the 1977 CHRISTMAS LECTURES was animated by the Ri animator-in-residence Andrew Khosravani.

    ‘A Place Called Space’ is the 2015 Royal Institution advent calendar. Every day in the run up to Christmas we'll be releasing an original piece of content exploring the human experience and cultural significance of space travel. With hand-drawn animations, experiments in zero gravity, interviews with astronauts and creative data visualisations, the calendar will fire you into space every morning.

    'A Place Called Space' channels the voices of seasoned astronauts and expert scientists through the eyes of a team of talented animators, film-makers and artists, bringing you a thought-provoking gem to kick-start each day.

Broadcast live on Friday, October 17, 2014, the event was a part of the National Air and Space Society Lecture Series.

    During his Naval career, Jim Lovell had numerous aviator assignments, including a 4-year tour as a test pilot at the Naval Air Test Center, Patuxent River, Maryland. He has logged more than 7,000 hours flying time--more than 3,500 hours in jet aircraft. Lovell was selected as an Astronaut by NASA in September 1962. He served as backup pilot for Gemini 4, backup Commander for Gemini 9, and backup Commander to Neil Armstrong for the Apollo 11 lunar landing mission. On December 4, 1965, he and Frank Borman flew on the Gemini 7 mission which lasted 330 hours and 35 minutes and included the first rendezvous of two manned maneuverable spacecraft.

    Rotation in Space - Professor Carolin Crawford

    51:19

    Rotation is a fundamental physical process throughout the Universe. So much is spinning, from planets and stars revolving on their axes, to whole spiral galaxies rotating around their centre. We shall start by looking at the fundamentals of rotational motion, including the concept of angular momentum. This then will be extended to show what observations of rotation can tell us about how planetary systems form and develop, how neutron stars evolve with time, and how rotational motion provides crucial evidence for the presence and distribution of the elusive dark matter.

    Introduction to Crystallography: Lectures 3 & 4 — Symmetry and Point Groups

    1:40:27

    A series of lectures and handout notes given by Dr. Cora Lind for her Chem 4980/6850/8850: X-ray Crystallography course at the University of Toledo (Ohio). These lectures introduce concepts in crystallography, such as the lattice, symmetry, single-crystal and powder diffraction, crystal structure determination and refinement.

    Lecture 3 relates the unit cell to the concept of the lattice and introduces the 14 Bravais lattice types. Then point symmetry elements -- the symmetry that can be found in discrete objects are introduced. Lecture 4 expands from symmetry of discrete objects to those of infinitely repeating patterns that fill space. This requires additional types of symmetry elements. Symmetry operations can be combined in a limited number of ways. For discrete objects there are 32 point groups, for infinite objects there are 230 space groups.

    Current Affairs Q&A 41st Week of 2016

    20:02

    “Current Affairs” is the most sought after discipline not only by students but also by various professionals. Learning Space tracks Current Affairs in a most comprehensive way week after week starting from 1st January 2015.

    Every week in our videos, we discuss various important events with analysis as “Capsules” (minimum six and maximum ten every week), other minor events in a “Question and Answer Format” and “News at a Glance format” with detailed/brief explanation. Hence, every week Current Affairs will have eight to twelve modules. The “Capsules” will be presented topic wise.

    This video is the “Q&A” for the period of 10th Oct to 16th Oct, 2016.
