Space & Tech newsdump

Busy with uni work and yes, projects! =P
[need to finish an Android app in two 1-week sprints that allows year 10 students to learn functional programming by doing it!]
So as pointed out already, I'll abandon the idea of posting news items as blog articles regularly. This doesn't mean I'll stop posting all news type articles though!

Because I don't want to spend the time regurgitating news articles in nice English, here's a link dump of noteworthy articles in the past few weeks: (it also serves as a personal favourite/bookmarker =P) =D

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!

Space.com's coverage, editor promises updates on this page:
www.space.com/27576-private-orbital-sciences-rocket-explosion.html

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

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.

The return of the ISEE 3

http://spacecraftforall.com/home


Great website with cool interactive documentary-like experience! Check it out! Also, it'll be live-streaming the fly-by of the moon in a few hours (Sunday, August 10th 10:30am PT - 12:00pm PT) , but I'll be asleep. Also includes live data anytime! =)

This whole project was crowdfunded and they (the hackers/makers) work in a hackerspace/mission-control in an old Maccas building! Lol! And with NASA's blessing =) Them talking about *SCIENCE* so much reminds me of stuff like Portal, xkcd, KSP (get them science points!) haha.

Also, great post about SoftwareDefinedRadio; been meaning to get my HAM radio callsign sometime soon ...

Also, the initial swing-bys to get to the 1st comet flown through by man is so cool and complicated, it reminded me of an epic version of this:
Ahem. We are STRICTLY an Orbiter shop.

I mean, orbiting in one plane is hard enough to learn (in a fun way) in KSP. Add in polar plane and crazy manoeuvres and orbits like Quasi-Zenith and I have to spend more time wrapping my head around more simulations, models and reading.
P.S. My short-term goal is to build and launch a (nano)sat in one of them Quasi-Zenith orbits servicing Australia =P Hopefully I'll get to crowdfunding when I've actually done work on it xP.

Australian Space Agency - why

Came across a good article here about why Australia needs a space agency, and how we can create our own solutions instead of piggybacking off others and be able to build a new industry which benefits us.


The ACSER seems pretty cool.
I wonder if the GPS module could be used for other Australian spacecraft ...

Also, if you read my Mt Stromlo (AIAA tour) post back in early August when AIAA Sydney Section toured Canberra, here are some projects that the AITC are looking at at the moment. Hope I get to participate soon =)

Falcon 9 v1.1 Maiden Launch!

Wanted to watch this live to get booster info but was someplace with no reception. 
Vid here:

Also this article is pretty cool. Here's the bit about the attempt at recovering the first stage:
Once it was back in the atmosphere, it lit its central engine to slow itself further. That's where things went wrong, though, as the booster started spinning. According to Musk, this "centrifuged the propellant"—spun it to the tank's walls and kept it from feeding into the engine. As a result, it hit the water hard, leaving the company's employees with pieces to recover. (This rocket didn't have landing gear anyway, and Musk said that the added hardware would act like fins to stabilize the spin.)
With the information they gained from this flight, however, Musk said that SpaceX has "all the pieces to do full recovery of the boost phase," which he expects to be attempted early next year. In the intervening time, the company plans to gather data on re-entry during two more flights.
Recovery won't be cheap. In response to a question, Musk estimated that saving the fuel to perform a controlled landing on water requires sacrificing 15 percent of the potential payload; returning to land will take a 30 percent cut. But Musk said the boost stage is about three-quarters of the total cost of the rocket, so being able to reuse it would provide a substantial net gain.
Beyond these findings, not everything was rosy about today's launch. SpaceX also tried to restart its second stage engine (which is necessary on some flight trajectories but not for today's launch). The engine "encountered a condition it didn't like during repressurization," though, and the process was shut down. Musk said that the company has a good idea of what went wrong, and will address it before the next flight.

NASA News - September 2013

OK, I'm a bit on the slow side but I blame my travels to Melbourne and having so much fun at a wedding and fellowshipping =)

NASA has finally announced that Voyager 1 has left the solar system!
This, after scientists weren't quite sure how to interpret the data which seemed to indicate that it sometimes was still in the solar system and sometimes not. But now NASA thinks that Voyager 1 has passed the heliopause and is currently travelling through interstellar medium!

I guess we could add one more to the tally at http://xkcd.com/1189/ and hope we don't have to add any more =P

Also NASA news, they have 3 candidate asteroids for potential exploration by bringing it to moon orbit or something like L1/L4 and sending astronauts to do some science on it!

And if you haven't seen this photo bomb yet, something more light-hearted =P

Ubuntu Edge ... Final Hours

While I posted about Ubuntu Edge before, It's at the final hours (17) of the campaign and with only 12.25mil and just under 20mil to go, it doesn't look very likely this crowd-funding campaign will reach its goal.

At the discounted price of $695/phone, that is now 46k units instead of 40k units, which is a decent manufacturing run, although I'm not sure on the exact numbers in the economical analysis of these things.

Spec-wise, and functionality-wise it trumps anything in that price-range, Xperia Z or HTC One. Unfortunately, probably due to inadequate advertisement/social media-ring and just not enough people ready to upgrade/commit (a lot of the early adopters may have already bought something this year like the previously mentioned phones), the campaign won't be breaking crowd-funding records like Star Citizen's record breaking crowd-funding dollars.

Still, 12mil is pretty respectable, it was 11mil yesterday and comes close to the 14.6 mil that Star Citizen had when I posted about Ubuntu Edge before (see previous blog post link). Right now Star Citizen has a whopping 15.7mil and growing everyday. Hangar module comes out 24th August at GamesCon, so can't wait to see the news and test it.
I hope they release something like an OpenGL version soon because apparently it'll be DirectX11 and my GT330m doesn't have that support T_T. Also, recent look at ATI's open source driver support leans me towards getting an ATI graphics next time. These nvidia binary blobs sometimes screw up and took me an hour to get my 319 driver working with Linux 3.8 and jockey -_-.



P.S. So for Systems Engineering Analysis (ENGN2226) I get to look at nanosats woot.

ArduSat is In SPACE!!! (and AIAA Sydney Section tour of Canberra)

omg it's SPACE!!!
So Greg Chamitoff came to speak at the ANU a couple of weeks back (with U Syd and AIAA) and he said everyday, his commander would wake him up with "Guess what? WE'RE IN SPACE!!! =D"

Anyways, ArduSat was launched into space in the early morning (AEST, which is similar to Japan time) between the AIAA tour days when some students from Sydney came over to visit Canberra's Aeronautical and Aerospace stuff =P

I was so tired helping out and staying up and waking before 9 that I skipped the live launch, but here it is in all its glory (launch at 47:30). Rocket is JAXA's H-IIB, ArduSat is piggybacking on the HTV-4 resupply mission to the ISS, and will be deployed off Kibō [yes, I was a bit annoyed with the pronunciation of Kibō xP]



ArduSat was my first Kickstarter project I backed with $1 =P (Poor student who really wanted to afford time for operation of ArduSat). It's also apparently partly built in Australia. And has a goal for education and science, you could buy time on the kickstarter and I assume before EOL they'll have time for other people to do some science/education with it! Test and learn your arduino programs on the spacecraft here! =)


Here's a video about AITC, one of the places (CDSCC, AITC, ATSB and ADFA/UNSW@Canberra)  where the AIAA tour went in Canberra; by a Melbourne Hackerspace/Maker Jonathan Oxer (who not so coincidentally worked on ArduSat):


UPDATE 16/7/2014:  I posted some photos of the AITC when we visited here. I posted a lot more (100+) photos on facebook back around when this post came out which you can view if you're my "friend". =P

ARKYD Funded & Apple buys Samsung products?

So ARKYD, the Space Telescope for everyone was successfully funded at $1.5mil, and they hosted a livestream broadcasted by spacevidcast (woot!), I'm sure you can see my comments during the livestream if you look hard enough =P

You can still join in the fun (pledge & get rewards) with the grace period: http://www.planetaryresources.com/arkyd-newsletter-signup/
I wonder if I'll actually get time on this telescope (without pledging enough for reward on time) as a student ... Was hopeful about Ardusat (1st kickstarter for me). 

Also, check out the sweet $99 pledge deal, you get planetary annihilation (a previous kickstarted game) and Richard Garriot/Lord British was backing it too! (He's so well connected, space tourist, Star Citizen friend, etc.)

Wish DSI did something like this. They seemed like the ones who would do something like this ... good thing PR got the ball rolling =)

- Break -

So I didn't know this before, but apparently Apple uses Samsung chips in their devices. As Samsung's biggest (read $billions/year) customer. Lol. #USPO&IPsucks

At first I thought astroid mining companies were laughable..

but then I was convinced from their business cases.
Mind you, they're still going to be like at least 50 years before massive monies get raked in, and it all depends on someone getting those earth to orbit vehicles cheap and accessible. Personally I reckon 20 years before real profit gets raked in.

Planetary Resources website doesn't have much in depth info, though they were first, and do have 'le google executive investor', if that means anything.

If everything the sleek Deep Space Industries website says is true, then the business case for one of these really will be alright, but it all depends on increased customers in space, in the long-term. Which if humanity should expand, would be the logical necessary step. DSI seems a bit more open than PR and heck, it reminds me of RSI which is always a good thing (positive reinforcement ftw). Props to them for making the "Firefly" their first spacecraft =P And if that isn't an obvious enough reference, 300+m asteroids are apparently useful for hiding from Darth Vader and Reavers". Sign me up =)

Nice surprise to see Daniel Faber is actually part of the team, heard a talk when he introduced the project he's behind - Antarctic Broadband, which in the process of their main goal, will put a "A satellite ground station capability at ANU Mt Stromlo." and also use the new space R&D space (lol) that they built for projects like these.

It's interesting to note that they are both USA companies, and will most likely be subject to Space Export laws, which means I need that citizenship if I ever work there. But I'll worry about that later.

I wonder what people would think if you meet an 'asteroid miner' and if companies like BHP will invest.
"So what do you do?"
"I mine asteroids."
"Oh, you mean on EVE? I've heard that's like, boringly grindy and tedious."
"No, like Armageddon Bruce Willis style. Except, I do the electronics and software, and no nukes... yet."


Vod:
Lol, the space colony animations reminded me of Macross and Gundam. Let's hope Gundam Earth VS Colonies wars never happens.
