2003 - millions watch live as Columbia breaks up in the sky over Texas, killing all on board. NASA, loved ones and investigators share how an incredible journey ended in tragedy. Chapter 1: As Nasa prepares Space Shuttle Columbia for its 28th mission, excitement and trepidation build amongst the astronauts and their families as they count down to launch. This programme hears from the seven astronauts - a mixture of veterans and rookies - and their families as they train for an awe-inspiring journey of a lifetime. Chapter 2: Nasa engineers analyse film footage of a piece of debris striking the shuttle Columbia 81 seconds after launch. What no-one yet knows is whether any serious damage has been done to the vehicle or the tiles which protect the vehicle against the intense heat of re-entry. But calls for photographs to be taken of the shuttle using satellites go unheeded. Meanwhile, in space, the crew continue their mission, unaware of any concerns inside Nasa. Chapter 3: Sixteen minutes from landing, mission control lose contact with the crew of Columbia. On the shuttle landing strip, families waiting to welcome their loved ones back home are swiftly ushered away. In the skies over Texas, locals hear a loud explosion, and debris strikes the ground in multiple locations. The fears of some Nasa engineers are coming true: Columbia is lost and there are no survivors. Following the disaster, Nasa comes under increasing pressure from the media to provide answers.

Today we’re rounding out our planetary tour with ice giants Uranus and Neptune. Both have small rocky cores, thick mantles of ammonia, water, and methane, and atmospheres that make them look greenish and blue. Uranus has a truly weird rotation and relatively dull weather, while Neptune has clouds and storms whipped by tremendous winds. Both have rings and moons, with Neptune’s Triton probably being a captured iceball that has active geology.

The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere - it's limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.

Everyone knows Neil Armstrong was the first to set foot on the moon. But this modest and unassuming man was determined to stay out of the spotlight. Now, for the first time, NOVA presents an intimate portrait of Armstrong through interviews with his family and friends, many of whom have never spoken publicly before.
