Rocket Lab succeeds in placing three satellites in orbit on second test launch

Capitalism in space: The small rocket company Rocket Lab successfully placed three smallsats in orbit on the second test launch of its Electron rocket yesterday.

I have posted the video of the launch below the fold. Everything unfolded smoothly and without any issues, including the video feed. This success bodes well for Moon Express’s effort to win the Google Lunar X-Prize, which has a deadline the end of March. Though Rocket Lab had said it wants to do three test launches before initiating commercial services, they have already initiated those services with the placement of three satellites by two customers on this launch yesterday. They have also hinted that if this launch was a success they might accelerate commercial operations.

In addition, ULA successfully launched a military satellite on two days ago with its Atlas 5 rocket. The 2018 launch stands are thus as follows:

4 China
2 ULA
1 SpaceX
1 Rocket Lab
1 Japan
1 India

I should add that though the U.S.’s total matches China at the moment, the government shut down prevents any further U.S. launches. It also prevents SpaceX from doing its Falcon Heavy static fire test. (I wonder: would this be an issue if SpaceX was launching from its private launchsite at Boca Chica?)

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions available at Amazon, Barnes & Noble, and all book vendors. The ebook can be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner. Note that the price for the ebook, $3.99, goes up to $5.99 on September 1, 2022.

 

Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95). Just email me at zimmerman @ nasw dot org.

    Great video!

    Q:
    At about 21:30 in this video–there’s a call for “hot-swapping,” and then a part of the rocket is ejected –to what does that refer & what are they doing at that point?

    Lots-o-factoids on the rocket. Very well done.

    >”hot-swap,”– dumping depleted engine battery packs.

    I’m expecting some feminist to get all upset because there were no women in the Rocket Lab control room…

    Facinating!
    I hadn’t paid attention to Rocket Lab and didn’t know about the electric turbo pump.
    Funny that it’s RL and not Tesla’s sister company that chose to use electric motors and LI batteries to drive it’s pumps.
    It’s been something the auto industry has kicked around – using an electric motor to drive a supercharger compressor rather than exhaust gas or a belt drive. The advantage is better control (no turbo lag) but the added cost/weight/packaging issues seem to have held it back.
    I wonder how disposable rocket use affected the calculations – the batteries don’t have to withstand multiple charge/discharge cycles and the motor can also be designed for a limited lifespan.

    Wonder how it will work out. If the small launcher market proves lucrative, I’d think Space X may be in a position to whip up a small launcher using 2 – 5 Merlins. They are mass producing (by rocket industry scales) Merlins and they have used (recovered) Merlins, so their engine cost should be quite low…

    Mitch-
    Good stuff!

    The battery pack they jettisoned apparently weighs around 200 kg. (ref: Scott Manley video) and they do use an inverter in the loop.

    Can someone dig into the specs on this? Do we know how much “electric” they need and for how long? (we’re going for amps, is that correct?)

    btw: Excellent staging-video!
    (I’d like more telemetry in the future, but not going to whine about it– great video all around!)

    -Totally fanciful and I don’t want to distract from the actual reality of the success–(I got wrapped up in Tesla-Stuff on the science-channel yesterday…) could we ever beam electricity to a rocket in flight?

    Did you just assume their gender? Report to the re-education super fun camp.
