SpaceX landing on floating platform in the ocean CONFIRMED! =P && Antares (by Orbital Sciences) explodes. =( UPDATED

SpaceX landing on floating platform in the ocean CONFIRMED! =P


So Elon Musk has confirmed SpaceX will attempt to land on a floating platform 90m*50m for their next Falcon 9 flight. YAY!

Florida Today:
He estimated no better than a 50-50 chance of a successful platform landing on the first attempt.
[...]
"So I think we're quite close," he said.
SpaceNews.com:
“We actually have a huge platform that’s being constructed in a shipyard in Louisiana right now,” Musk said in the interview, which was webcast live. He described the platform as about 90 meters long by 50 meters wide. “We’re going to try and land on that on the next flight.
“There’s at least a dozen launches that will occur over the next 12 months,” Musk said. “I think it’s quite likely — probably 80 to 90 percent likely — that one of those flights will be able to land and refly.”

Antares (by Orbital Sciences) explodes. =(


Sadly, the Antares rocket has exploded seconds after launch for their CRS-3 mission:


From simple visual inspection of this video, it seems like an engine failure for one or both engines - from the small engine flash and subsequent smoke; (or other failure causing engine flame-out or automatic shutdown). Subsequently, with no thrust, the rocket fell back to earth and the impact caused the big explosion.

Cargo carried included normal CRS foodstuffs, experiments, etc, and the Arkyd3 - a testbed for Planetary Resources' telescope satellites, including one which was Kickstarted (including a contribution from yours truly). 

According to Wikipedia, Orbital Sciences hasn't had that many failures, with successes in all Minotaur vehicles and the Pegasus with 3 outright failures and 2 partial successes (on primary payload) early in their launch history.Note that this is in line with many launch vehicle companies including SpaceX, whose Falcon 1 platform was their testbed which failed 3 out of 5 times.

However, SpaceX's Falcon 9 has had no failures except 1 secondary payload failure over its 13 total launches these last 4 years. Add to that: NASA pays $1.6 billion to SpaceX to deliver cargo over 12 missions while they have to pay $1.9 billion to Orbital Sciences for only 8 missions. Add to that each mission delivering more cargo in the Dragon by mass than Orbital Sciences' Cygnus spacecraft. The Cygnus is only superior in delivering more pressurized volume than the Dragon, and can't return cargo to Earth like the Dragon does.

Talk about SpaceX cutting costs and competition savings! (The citizens of USA should be glad SpaceX is now able to compete for USAF/DoD/NRO contracts.) I'm glad it's SpaceX that won the CCDev contract, and has a really cool Dragon V2 crewed spacecraft coming out, designed for reusability and landing by thruster functionality. Hurray for SpaceX reusability - providing sustainable and cheaper access to space!

UPDATE:


More about the accident and engine here: http://www.spacenews.com/article/launch-report/42340antares-rocket-explodes-after-liftoff includes spectator video and sound of explosion:


Press conference at 9pm ET (12pm AEDT, now) on Nasa TV

Broadcast live streaming video on Ustream

More updates to follow probably; from conference:
Emphasis of launch/rocket science and space science being hard (obviously). No injuries, only lost hardware.
Orbital Sciences - will investigate what's wrong, solve the problem and prevent future problems.
Investigation includes evaluating debris (like aircraft investigations [like ATSB]!) - don't touch debris, could be dangerous.
Wallops - good range clearing of safety area.
ISS - incl crew in good shape, have supplies for at least 4-6months always, Progress spacecraft tomorrow, SpaceX on Dec 9, quite a bit of research hardware lost and spare hardware.

Investigation data and everything locked down until investigation process goes through; wait for daytime for debris collecting. Solid propellant burning in area. Contract - provides for ability to eventually get hardware lost on this flight to orbit, Orbital compensates NASA if they don't reach orbit. Launchpad could be damaged, tank pressure sensor readings still available and holding pressure - extent of damage not known until fully investigated.
Engine failure observed in telemetry and visually ~T+10s and range then sent the destruct command ~T+20s, before it hit the ground.
Investigation: Orbital in command, supported very well by NASA and MARS (@Wallops), debris in morning, cameras, telemetry/data. Orbital obviously won't fly until they know and correct the problem.
Insurance - Orbital does have various/some amounts of insurance on their launches.
Engines - Orbital chose to go with this (Russian) engine as there weren't many choices for powerplants of this size, especially in USA, and it was extensively tested and has proved robust. They've also chosen another engine for future Antares, according to the link above providing the video of spectator view. Wonder if they considered using SpaceX's engines =P

Hoverboards are here!


Nerdist explains:
http://www.nerdist.com/2014/10/its-finally-here-a-hoverboard-you-might-actually-buy/
The Hendo hoverboard uses Lenz law which means it uses currents in the medium below to create magnetic fields to repel those on the hoverboard.

So water can have currents in it, but will that be enough to hover? And you'd probably need rockets to propel you like with Marty McFly's adversary right? =P

Want one? Grab one for $10k at the kickstarter or a dev kit for $300:

Elon Musk Unveils the 'D' and something else


I really like it when Elon talks nerdy. So Elon Musk unveiled the 'D' - dual motor version of the Model S which means it actually now has better fuel/battery efficiency than the single motor version! The weight is offset by the efficiency gained by dynamically shifting power between front and rear motors during the drive! Check out his reveal below.



But the highlight has to be the autopilot! I've been wanting a car with significant driver assist features like those introduced in the video above. I mean, it's like a bat-mobile (ultrasonics anyone?)! I'm surprised they didn't put the rear-view camera into the sensor mix for autopilot, but I guess the ultrasonics is a much more reliable input, and they could always add in the extra sensor input via software updates. Every car for the past 2 weeks has come from the Tesla factory with all the autopilot hardware!

Features like full computer control, driving to where you want on your private property via your synced calendar (e.g. main entrance to pick you up for work/[LAN] party). He made a Metal Gear Solid pun too!! While telling his engineers of a new feature he'd like!! xDDD Now I'm thinking - forget the Model 3 as my future car purchase when I actually earn full-time, I'm going for the Model S with autopilot second hand haha.

Here are the Autopilot Sensors:
Radar - see through stuff like fog, I'm thinking because of the larger wavelength.
Forward Camera -  CV ftw.
360 Ultrasonar - apparently senses soft material like flesh really well
Satellite/Nav - Includes traffic info (like the creepy Google ones)

Here's Tesla's blogpost. Also, the video below shows the test-drive ride inside:


On the stock note, it dropped a bit after the hype from the twitter post, but Elon's not worried and neither am I. Elon's in this for the sustainability standpoint of long-term sustainable energy use and transportation. Fossil fuels will never be sustainable nor clean.

UAV OutBack Challenge update & Bonus Space Pic

As expected, CanberraUAV - who almost completed the UAV Outback Challenge last time - won the challenge, taking home $50k in prize money. 2 years ago they failed only because their bottle deployed unintentionally during flight. This year, they got the bottle within 3 metres (2.6) of Outback Joe (who they're trying to find and rescue with a bottle, in this S&R competition scenario).

Here's a great write-up debrief by them:   (obligatory iframe)

Make sure to check out the really cool software they put up on github! And also that documentation repo. One of the coolest things about CanberraUAV is how open they are (as in open-source), and how much they share with other teams!

Unfortunately, while the Monash UAS team's (which I joined recently) plane flew very well, they couldn't find Joe. I'll be going to the internal debrief on Tuesday and hopefully learn more, as well as try and locate Joe using (augmentations of) our software from our data gathered.

Space pretties incoming! Check this photo! (link to NASA APOD page)
Much wow. So mind-bend - how?!. Also check out a lot of the guy's other really cool photos. I obviously really like the aurora photos in his gallery.

Star Citizen claims Guiness World Record - Most Crowdfunded Project Overall

Hey guys, I (kind of) got into the Guiness Book of World Records!!! (well CIG did, but I backed Star Citizen so ... =P)

Guiness Book of World Records 2015, page 17:
- Flash/HTML version
- SEO version

And this was when Star Citizen had raised $39.6 million back in March, and it's now over $55 million!!! Note that sponsorships and subscriber monies do NOT count towards the total you see on the funding goals webpage.

In the latest Letter From the Chairman, Chris Roberts describes CIG's budgeting planning, and how 'feature-creep' is actually part of the agile development process, with "creeped" features coming after Persistent Universe v1.0 release, although others may come before that since they're able to with increased funding, like higher fidelity ship models.
Go agile! (I'm glad I'm being taught Agile at my current uni, whereas I in the previous one I only touched waterfall/Vmodel. Maybe it's because I switched from hardware to software, but the idealogy should be taught/learnt anyway!)

You can also see other crowdfunded projects (also on page 16, it's a double page spread), including the pebble smartwatch (which came out before all the latest watches like Samsung, Sony and Apple's current-gen offerings). It features e-ink which is cooler and less battery draining than LED/LCD but is monochrome. I wrote about both Star Citizen and Pebble last year here
