SpaceX targets January launch as investigation into Falcon 9 explosion is completed

SpaceX has confirmed that following the outcome of an investigation into how its Falcon 9 rocket exploded in September 2016 it will relaunch the craft on January 8.

For the past four months investigators, which included officials from the Federal Aviation Administration, the US Air Force , the National Aeronautics and Space Administration , the National Transportation Safety Board and several industry experts, scoured more than 3,000 channels of video and telemetry data covering a very brief timeline of events in order to establish what anomaly caused Falcon 9’s explosion in September.

The team concluded the failure was likely due to the accumulation of oxygen between the COPV liner and overwrap in a void or a buckle in the liner, leading to ignition and the subsequent failure of the COPV.

Falcon 9 uses COPVs to store cold helium which is used to maintain tank pressure, and each COPV consists of an aluminium inner liner with a carbon overwrap. The recovered COPVs showed buckles in their liners.

The accident investigation team worked systematically through an extensive fault tree analysis and concluded that one of the three composite overwrapped pressure vessels (COPVs) inside the second stage liquid oxygen (LOX) tank failed.

However, the team also identified several other credible causes for the COPV failure, all of which involve accumulation of super chilled LOX or SOX in buckles under the overwrap.

In response, SpaceX has put into place a number of corrective actions that address all credible causes and focus on changes which avoid the conditions that led to September’s explosion.

In the short term, this entails changing the COPV configuration to allow warmer temperature helium to be loaded, as well as returning helium loading operations to a prior flight proven configuration based on operations used in over 700 successful COPV loads.

In the long term, SpaceX will implement design changes to the COPVs to prevent buckles altogether, which will allow for faster loading operations.​

The rocket that SpaceX plan to launch on January 8 will launch from Vandenberg’s Space Launch Complex 4E (SLC-4E) with the Iridium NEXT satellite aboard.

Using CRISPR, UK scientists edit DNA of human embryos

For the first time in the UK, scientists have altered human embryos. Using the gene-editing tool CRISPR, the scientists turned off the protein OCT4, which is thought to be important in early embryo development. In doing so, cells that normally go on to form the placenta, yolk sac and foetus failed to develop.

Synthetic muscle developed that can lift 1,000 times its own weight

Scientists have used a 3D printing technique to create an artificial muscle that can lift 1,000 times its own weight. "It can push, pull, bend, twist, and lift weight. It's the closest artificial material equivalent we have to a natural muscle," said Dr Aslan Miriyev, from the Creative Machines lab.

Scientists engineer antibody that attacks 99% of HIV strains

Scientists have engineered an antibody that attacks 99% of HIV strains and is built to attack three critical parts of the virus, which makes it harder for the HIV virus to resist its effects. The International Aids Society said it was an "exciting breakthrough". Human trials will begin in 2018.

Renault unveils unorthodox ‘car of the future’: a dockable, peanut-shaped driverless pod

Renault has unveiled its take on the car of the future: a peanut-shaped, mulit-directional driverless vehicle that is capable of docking into a train of vehicles.

Designed by Yuchen Cai, a student of Central St Martins’ MA in Industrial Design, the vehicle is the winning design in competition run between Renault and the prestigious design school, and was honed during a two-week stay at Renault’s Paris studio by Cai this summer.

Dubbed The Float, the vehicle was unveiled today at DesignJunction, a four-day design event that kicked off today in London.

“Everyone has accepted that cars will be part of the sharing economy in the future – that’s what’s going to happen,” said Will Sorrel, event director of DesignJunction, this morning.

“This takes it one step further and these pods are this peanut shape so they can join together, so the autonomous vehicles can link up and join together if they’re going in the same direction, conserving energy.”

The Float is rather unusually designed to run using magnetic levitation – known more commonly as maglev – and would be capable of moving in any direction, eliminating the need for tedious three-point turns.

Made entirely of glass, the vehicle is designed to have sliding doors. Two bucket-style seats enable up to two passengers to travel per pod, and swivel mechanism ensures easy departure from the pods.

When the vehicle is docked to another, however, the passengers aren’t just stuck grimacing at each other through glass. Instead passengers can rotate their seats using built-in controls and power up a sound system that allows them to talk to the pod next door.

Those who are feeling less sociable can change the opacity of the glass, ensuring privacy when their neighbours are not so appealing to communicate with.

The Float is also designed to be paired with a smartphone app, through which would-be passengers could hail a vehicle as required.

“Central Saint Martins’ Industrial Design students really took this on board when creating their vision of the future,” said Anthony Lo, Renault’s  vice-president of exterior design and one of the competition judges. “Yuchen’s winning design was particularly interesting thanks to its use of Maglev technology and its tessellated design. It was a pleasure to have her at the Renault design studios and see her vision come to life.”

“From a technological viewpoint, the prospect of vehicle autonomy is fascinating, but it’s also critical to hold in mind that such opportunities also present significant challenges to how people interact and their experience of future cities,” added Nick Rhodes, Central Saint Martins programme director of product ceramic & industrial design.

“Recognition of the success of the projects here lies in their ability to describe broader conceptions of what driverless vehicles might become and how we may come to live with them.”
