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

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.

SpaceX reusable rocket video (SpaceX does it again!)

So reusability landing footage from last week's successful SpaceX-Orbcomm mission has been released by SpaceX! Apparently this time no file repairing was needed like last time when they crowd-sourced help for repairing their mpeg via reddit =P.
There is however, icing, which blurs/obscures the video quite a bit.



SpaceX's full blog/news post (quoted at the end) has more information, including that they touched down at close to 0 velocity, and the next 2 flights they will not attempt reusability tests since they are higher orbits (GTO). However, after that on flights 13,they will test landing on water and (flights 14, 15) on solid ground with increased chance of success. Apparently it's easier to land on land than on water?! (It could however, be just a platform in the ocean.)
I'm guessing they have great control over where they're able to land. (It's harder to gauge when and how to burn by eye/hand when landing from orbit to KSC in KSP -which was recently 40% off on Steam and now features contracts and rewards for recovery of things like boosters/stages =P)

Here's the full quote from the SpaceX blog (because the info is so juicy):
Following last week's successful launch of six ORBCOMM satellites, the Falcon 9 rocket’s first stage reentered Earth’s atmosphere and soft landed in the Atlantic Ocean. This test confirms that the Falcon 9 booster is able consistently to reenter from space at hypersonic velocity, restart main engines twice, deploy landing legs and touch down at near zero velocity.
After landing, the vehicle tipped sideways as planned to its final water safing state in a nearly horizontal position. The water impact caused loss of hull integrity, but we received all the necessary data to achieve a successful landing on a future flight. Going forward, we are taking steps to minimize the build up of ice and spots on the camera housing in order to gather improved video on future launches.
At this point, we are highly confident of being able to land successfully on a floating launch pad or back at the launch site and refly the rocket with no required refurbishment. However, our next couple launches are for very high velocity geostationary satellite missions, which don’t allow enough residual propellant for landing. In the longer term, missions like that will fly on Falcon Heavy, but until then Falcon 9 will need to fly in expendable mode.
We will attempt our next water landing on flight 13 of Falcon 9, but with a low probability of success. Flights 14 and 15 will attempt to land on a solid surface with an improved probability of success.
Space Age, here we come!!! =D

Tesla Confirms Bluestar as Model III, not E

Yes! Name of Tesla's Bluestar finally confirmed
Haha, didn't know Elon Musk wanted to spell SEX with his model "numbers" but Ford sued them for the E. 

This coming from the company that recently open-sourced its patents (for the good of sustainability and EVs)! 

Quick update, so obligatory iframe:

Quick Space Update =D

 

AITC installs Wombat XL

Close to (my) home, Australia is finally moving along in the space industry with our first satellite testing facility at the Australian National University! The last time I was there they didn't have the Wombat vacuum tank in the big testing room. Let's see if I can upload a picture of what I saw (great view!): on second thought, he's some pics from the AITC from when we toured there!

The room where the Wombat XL Space Simulation Facility now sits
Dang, that view (Canberra's pretty!)
Crane in the clean room
Clean room




soon-to-be vibration platform

Sometimes moving images around is so difficult, even in this WYSIWYG blogger editor I would rather LaTeX. (html layout formatting is horrible imho)
ANU hopes to test their HDLT plasma thruster there. (Past research students in the group have said their previous conclusions were "need bigger vacuum chamber", so here it is! =P)

SpaceX launches 6 OrbComm satellites, gets aproval for Texas private launch site, and passes 3 flights EELV requirement

100% mission success. Reusability testing was good (again) up until splashdown.


They got approval for their first private spaceflight facility. It even has a wiki page! This allows SpaceX to"provide SpaceX an exclusive launch site that would allow the company to accommodate its launch manifest and meet tight launch windows." Especially that rapid reusability time - land on your own launchpad, recover, reintegrate, refuel, launch without worrying about range clearance blocking you because it'd be planned already.

Also, USAF certifies SpaceX's Falcon9 3 successful flights, amid the legal battles they have had.


UK Spaceport and user roundup

Astronomy Agregator does a good UK Spaceport and reusable/SSTO/Sub-orbital round-up of the Spaceport's users and critique.
Speaking of my favourite space outlets (apart from the big ones like NASAspaceflight, spaceflightnow, space.com) I haven't been on AA or ParabolicArc or Spacevidcast in a while. I'll be happy to get back into it! =)
Spacevidcast's new show is now called TMRO ("tomorrow") and are on Patreon, so support them, because they do really great weekly shows!


Space Games

Space genre games have seen a resurgence, imho in no small part due to Star Citizen's rocketing success, and a lot of them are on Linux =D Here's updates from the biggest 2 (and my personal favourites) space games!

CIG at RSI.com on StarCitizen surpasses $48 million in funding and has almost 500k Star Citizens at time of writing! All the stretchgoals!! It doesn't look like we'll get the bagel carrier mentioned in an old WMH episode xP but we do get complete alien languages with the hiring of linguists!!!

Kerbal Space program is releasing 0.24 soon and has prepped this FAQ for us. After the NASA-partnered 0.23.5 Asteroid Redirect Mission update (with a stock asteroid grapler/claw), this is a welcome update with funds, reputation and contract functionality to further enhance the career mode! No longer will you build with unlimited money and have no repercussions of killed kerbonauts! =P I hope those interstellar mods and life support, real communication link, KOS and MFD mods still work ... Would love to do a full mission in first person!


Hurray for indies and startups! (All news items today have had a connection to this theme). Especially newspace! =)

Making fuel from seawater, FOSS, USPTO and copyright

The US navy is researching methods to make fuel from seawater and have a working prototype!
This has been a many-year effort.
Basically CO2 is extracted from sea-water by acidifying seawater with HCl and using electrolysis to extract CO2 and H2.
Then, using a Fischer-Tropsch catalyst and high temperatures (190C) long-chain hydrocarbons can be formed. 

Both main reactions/processes are obviously endothermic and require energy, so you wouldn't expect a ship to make their own hydrocarbon fuel and run on it, so ships can't be self-sufficient and not need to dock for fuel. However, it also means a whole new supply chain can be opened up which don't require traditional shipping/supply of oil from oil rigs and mines around the world.

----------------------------------------------

Yay for Linux on military drones courtesy of Raytheon! It might be a smart move to do stuff like open API for cost redundancy reduction and inefficiency reduction. Security through obscurity is not real security, so it's arguable no less safe than a proprietary *nix system like Oracle.
http://www.gizmodo.com.au/2014/05/us-military-drones-are-going-to-start-running-on-linux/

---------------------------------------------

Speaking of open APIs, wtf is this:
Oracle granted API copyright, wins vs Google.
I mean, we've been down this road before with software patents and all their predicted detriments, and now you can copyright an API. Not sure how closely your API can resemble another's but this is treading deep into the patenting an idea. Maybe in 10 years time I can patent the idea of mining asteroids, even though Planetary Resources and Deep Space Industries would have been going at it for 10+years. Then I'll just receive royalties from any enterprising new-space company or project and live in luxury while drowning my guilt and shame and morality in loads of ice-cream. Also, everyone will have to hire more lawyers and the ratio of lawyers to engineers, scientists and other staff would be 50-50 in any technology company. And all the lawyers will be busy doing nothing but harming everyone.

And speaking of horrible copyright and patent rulings, if you know me you should know how much I look down on the USPTO - I have no hope in it. I mean, they just let Amazon patent taking photos against a white background! Watch out, passport photo takers! - That Star Trek double face-palm image is quite apt, so is "credibility reaching zero".

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.

Total Recall (1990) is totally real

New measurements of Mars' south polar region indicate extensive frozen water. The polar region contains enough frozen water to cover the whole planet in a liquid layer approximately 11 meters (36 feet) deep. A joint NASA-Italian Space Agency instrument on the European Space Agency's Mars Express spacecraft provided these data.

We can totally terraform this stuff. (And also dump our carbon there =P).

Now I'm wondering if the moon has enough water ice to make a moon base have all their water and fuel needs taken care of.

Russian Satellite Hit by Debris from Chinese Anti-Satellite Test [space.com]

So I feel like we're past the point where we can be passive about the problem and expect spacejunk to be negligible and avoidable.
Either PLA wanted to make space access harder for everyone once it secured manned spaceflight, or they have bigger egos than brains, or they don't understand sustainability. That graphic with the debris and ISS orbits is pretty freaky (below).

Also the tracking data seems to have large uncertainties or the statistics aren't to be trusted. -It's the 2nd time a mid-low chance of collision actually happened (there were higher probabilities of collision and closer aproaches by other objects each day).

 Also, ISS has manoeuvred as a result of avoiding this exact debris cloud's object.

If you want to learn more on the subject while being entertained, a good starting point is this movie:
This theatre highly recommended. Only criticism I have is that them red-cyan "goggles" make your FOV significantly smaller, making you have to look around a little sometimes. Non-3D shows have the advantage of filling your FOV with planetarium screen goodness, especially if you're at the back =) Also, any student ID is valid (Y)
