Space Sunday: rockets and rovers

Elon Musk has announced the first payload that will be flown aboard the SpaceX Falcon Heavy, together with an ambitious goal in mind.

The maiden flight of the new heavy lift launcher had been expected to take place in December, as a part of an ambitious end-of-year five launch schedule. However, in tweets on Friday December 1st, 2017, Musk indicated the Falcon Heavy flight will now take place in January 2018. When it does, and if all goes according to plan, be sending Musk’s own car on its way to Mars – and possibly beyond.

Announcing the push-back on the Falcon Heavy launch

A car might sound a weird payload, but it is entirely in keeping with SpaceX’s tradition; the first Dragon capsule test flight in 2010 carried a giant wheel of cheese into space.

The first tweet on the launch also underlines Musk’s own uncertainty about its potential success; he has previously stated that he expects the first flight of the Falcon Heavy may end in a loss of the entire vehicle, simply because of the complexities of the system.

And the announcement about the payload and its (initial?) destination.

Comprising three Falcon 9 first stages strapped together side-by-side and firing 27 main engine simultaneously at launch means the vehicle will be generating a tremendous amount of thrust requiring all three stages to work smoothly together. They’ll also be generating a lot of vibration during the rocket’s ascent through the denser part of the Earth’s atmosphere. Only so much of this can be simulated and modelled; a maiden flight is the only way to find out where the remaining issues might lie.

However, if the launch is successful, it will be spectacular, involving the recovery of all three Falcon 9 stages to safe landings back on Earth. It will also boost Musk’s car towards Mars – which raises a question. Does SpaceX aim to orbit the car around Mars, or will the mission simply be a fly-by?

Any attempt to achieve Mars orbit would require some kind of propulsion system to perform an orbital insertion burn, something which adds complexity to the mission. However, given Musk’s ambitions with Mars, placing even such an unusual payload into Mars orbit could yield valuable data for SpaceX. The car weighs 1.3 tonnes, so the total mass launched to Mars – car (likely modified somewhat, although the stereo will – according to Musk – be playing David Bowie’s Space Oddity during the ascent) payload bus, propulsion system, fuel, some kind of science system (why orbit Mars only to pass up the opportunity to gather data?) – could amount to around double that, if not more.

Musk’s comment about the payload being in “deep space for a billion years” seems to suggest the mission might by a fly-by, sending the car onwards and out across the solar system and beyond. Again, with a science payload sharing the space with the car, this could generate useful data. Either way the launch of such an unusual payload is likely to require additional US Federal Aviation Authority (FAA) approval; it will certainly require a launch license – which the FAA has yet to grant.

NASA Turns to Lunar Rover to Help With Next Mars Rover Mission

I’ve followed the Mars Science Laboratory (MSL) mission, more generally referred to as the Curiosity rover mission since 2012, tracking the discoveries made and the ups and downs of the mission. Overall, the rover has carried out some remarkable science and made a range of significant discoveries concerning ancient conditions within Gale Crater on Mars and the overall potential for the planet to have been able to potentially support microbial life at some point in its history.

But there have been hiccups along the way – computer glitches, issues with some of the rover’s hardware, and so on. These included was the 2013 discovery that Curiosity’s wheels were starting to show clear signs of wear and tear less than a year into the mission. The discovery was made during a routine examination of the rover’s general condition, carried out remotely using the imaging system mounted on Curiosity’s robot arm.

This image taken on April 18th, 2016 (Sol 1,315) by the Mars Hand Lens Imager (MAHLI) camera on the rover’s robot arm revels areas of damage on Curiosity’s centre left wheel, the result of periodically traversing very rough terrain since the rover arrived on Mars in 2012. Credit: NASA/JPL

The images captured of the rovers six aluminium wheels, each some 50 cm (20 inches) in diameter, revealed tears and a number of jagged punctures in one of them (above), the result of passage over the unforgiving, uneven and rock-strewn surface of Mars. While damage was not – and has not – become severe enough to threaten Curiosity’s ability to drive, at the time they were found, it did cause mission planners to revise part of the rover’s mission as it drove along the base of “Mount Sharp” near the centre of the crater, in order to avoid traversing a region shown from orbit to be particularly rugged. Since then, care has been taken to avoid exposing the rover to particularly rough areas of terrain.

Hollywood Art Museum to open In Sansar with Star Wars event

The next instalment of the Star Wars film franchise opens in the United States on Friday, December 15th, 2017, in the form of Star Wars: The Last Jedi. However, on Saturday, December 9th, 2017, Star Wars fans will be able to enjoy a special Star Wars related treat in Sansar, when the virtual Hollywood Art Museum (HWAM) opens its doors to the public.

A joint endeavour between Sansar Studios and renowned director, designer, writer, producer, and practical effects professional, Greg Aronowitz, the Hollywood Art Museum is dedicated to the preservation and education of art used in entertainment.

Mr. Aronowitz – whose credits such as Jurassic Park: Lost World, X-Files, Saving Private Ryan, Contact, Terminator 2, and Dark Crystal: Age of Resistance – is an avid collector who has amassed an incredible collection of Hollywood production art, from storyboards to costume sketches, concept drawings, models, and more.

These pieces provide an intimate view into the creative process behind some of the world’s most beloved films, spanning a period from Citizen Kane to Transformers: The last Knight, and present a unique visual history of production art in Hollywood. Until now, his collection has been inaccessible to the general public – that changes with the launch of the Hollywood Art Museum.

The museum’s goal is to help new artists using digital mediums find fresh inspiration in the traditional arts of Hollywood’s past. Exhibits at HWAM will feature high-resolution images of the original drawings and paintings, as well as 3D models of production used sculptures, make-ups, miniatures, and tools.

To mark both the opening of the Museum, and in recognition of the upcoming new film in the Star Wars franchise, Mr Aronowitz will be hosting a private pop-up gallery on Saturday, December 9th, 2017 at one of Los Angeles’s oldest art supply stores. This location also happens to be where George Lucas’s visual effects company, Industrial Light And Magic, acquired many of the supplies used to create visual props and other elements used in the original Star Wars films.

The event will feature original physical art from the franchise, including the very first drawings made for the film franchise and never-before-seen production art from the first trilogy by Lucasfilm alumni Joe Johnston, Ralph McQuarrie, Phil Tippett, Drew Struzan, Colin Cantwell, and more.

In addition, there will be VR stations where attendees at this live event can visit the museum’s presence in Sansar. Then, during the week commencing Monday, December 11th, 2017, Greg Aronowitz will provide daily guided tours of the gallery, and there will be special surprise guests dropping in.

Sansar users will also be able to visit HWAM in Sansar from Saturday, December 9th, and join in with the celebrations, as well as being able to visit the museum any time thereafter.
