Anonymous asked: How would you compare what Rocket Lab is doing to what SpaceX is doing?

I think it comes down to different missions, SpaceX is in it to eventually put people on other planets, which is a long way off atm. RocketLab want to provide a economically viable platform for companies to launch satellites into orbit.

SpaceX has an average mission cost of about $100 million, something only Governments and high end companies can afford while Rocketlab’s electron rocket costs only $4.9 million to put a satellite into orbit.

Of course SpaceX does have the job of resupplying the ISS as well as other, more tasking missions, but regardless of that, a space program costing that much per mission is not sustainable. It Needs to be cheaper, which Rocketlab have accomplished with their light weight design, and efficient engine.

About two weeks ago Rocket Lab, an NZ firm based in Auckland, announced a new satellite launching rocket. 
The super-light weight design is comprised of advanced carbon fibre technology, combined with the efficiency of the patent pending Rutherford engines, (named after NZ born physicist Ernst Rutherford) the rocket will be able to deliver a 110kg (242 pounds) payload to a 500km (310 miles) orbit for an amazing $4.9 million! 
This probably doesnt sound like much, but with todays electronics 110kg is enough for any satellite, and the amazing thing is - $4.9m is barely anything compared to the $56-$100 million of other launch systems. $4.9 million is approximately 1000 times cheaper than each of the apollo missions.
Not to mention the incredibly low amount of fuel use - less than it takes to fly a 737 from San Fran to LA!
The figures speak for themselves, and as such rocketlab have already booked over 37 launches, with the first scheduled for next year. The ultimate goal is to be launching 100 a year.
And on a personal note - as i actually live in Auckland - I am So excited to see this happen! 100 launches a year = 2 a week, from what will hopefully be a launchpad within driving distance of home!

Andean cock-of-the-rock (Rupicola peruvianus)

The Andean cock-of-the-rock is a medium-sized passerine bird of the Cotinga family native to Andean cloud forests in South America. It is widely regarded as the national bird of Peru. The species exhibits marked sexual dimorphism; the male has a large disk-like crest and scarlet or brilliant orange plumage, while the female is significantly darker and browner. Gatherings of males compete for breeding females with each male displaying its colourful plumage, bobbing and hopping, and making a variety of calls. After mating, the female makes a nest under a rocky overhang, incubates the eggs, and rears the young, all by herself. The Andean cock-of-the-rock eats a diet of many organisms. It consistently eats fruit and occasionally feeds on insects, amphibians, reptiles, and smaller mice.photo credits: chdwckvnstrsslh, Robert Baker, Glenn Bartley

Does the “7 Minutes Of Terror” sound like a cheesy horror flick or a theme park ride to you? It’s not. That’s the phrase NASA used to describe the entry, descent and landing (also known as EDL) sequence of the Mars rover, Curiosity. Seven minutes is the time it took for Curiosity to go from the top of the Martian atmosphere to the surface of Mars. It was by far the most complicated and ambitious Mars landing ever attempted.

It required a carefully orchestrated set of maneuvers that had to be controlled entirely by computer. Even the slightest error could mean disaster. The spacecraft began to decelerate as it entered the Martian atmosphere and was guided using small rockets, then at approximately 1,000 mph a supersonic parachute was deployed to further slow the descent allowing the heat shield to separate at around 370 mph. Curiosity then separated from its parachute and began its powered descent at 70 mph using retrorockets that slowed the rover and brought it close enough to the surface that it could be lowered to the ground via a sky crane. It was a daring feat of engineering that captivated the world had everyone holding their breath until they heard the words of the mission controller, “Touchdown confirmed. We’re safe on Mars!”

"Hey Buddy, Your Gills Are Showing!"

Nudibranches, also known as true Sea Slugs, are some of the most colorful creatures on earth. In the course of their evolution, these members of the mollusk family, lost their shell while developing alternative defense mechanisms. The name, Nudibranch, means “naked gills”. These gills (branches) can clearly be seen in each of the images above. The twin structures at the opposite end of these creatures are called Rhinophores and are used to sense chemicals in the water.

Nudibranchs are carnivorous, feeding on invertebrates like sea sponges, hydrozoids and sometimes other nudibranches. Some of them are even known to store toxins from their prey for future use. The bright colors of these creatures warn predators that they are poisonous. Nudibranchs are hermaphroditic and bear a set of reproductive organs for both sexes, though they cannot fertilize themselves.

Despite Appearances, this creature, the Wolf Eel, is one of the natural worlds true wonders - they are remarkably friendly.
Wolf eels having never seen a human diver before will not fear it, not attack it, but investigate and most likely come to the conclusion that this human can help scratch its back.
They are the worlds friendliest animals!
(Someone asked ‘but what about dogs?’ and, well, have you tried petting a wild dog…?)

The glass tank is filled with a gas called Sulfur Hexafluoride which is a one of the more dense gases, and it also happens to be as transparent as air so it gives the illusion of something floating in mid air, when it is really just acting like a boat in water.
