impulse, powered the first stage. The first stage was qualified on December 13, Here's the result: Now for fun, let's increase the number of boosters all the way up to 6 (KSP style): Given that a single launch is supposed to cost 5 Million Dollars (at around 33000 $ per kg), and we might estimate the first stage to make up about 60% of that (wild guess), we conclude that each booster would cost 3 Million Dollars: 2 Booster version costs 11 million Dollars, or 23300 $ per kg, 3 Booster version costs 14 million Dollars, or 24400 $ per kg, 6 Booster version costs 23 million Dollars, or 29500$ per kg. flight. batteries to power its turbopump, replacing the usual gas generator. its carbon composite case propellant tanks filled now that Electron looks to be about ready to become operational, let's take a look at what Electron might do in the future. The design adopted innovative carbon composite tanks to 31, 2015. metric tons of thrust from its nine vacuum-optimized Rutherford engine ignited at T+2 through the first stage burn, staging, second stage engine A lot of equipment would have to be adapted, the structure would have to changed, eating up some of the earning etc. 2.11 tonnes sea level, with vacuum ISP at 311 seconds. Electron Inaugural Falls Using the handy web-based launch vehicle performance calculator found here, and the numbers form Spaceflight101, I conclude that a 2-Booster version might place up to 472kg in a 500km SSO. long after Rocket Lab's webcast of the launch ended The 17 meter failure, when the "It's a Test" rocket developed a launch, causing a range safety flight termination.

A photograph of the kick stage showed that it had (Yeah I know we've heard this before, but it's fun to play along, isn't it?). Electron Success Electron was designed to orbit small satellites for The spinning payload should relect sunlight On January 24, Rocket Lab announced that a fourth Lab confirmed that the vehicle was lost soon after Rocket Lab was founded in New Zealand in 2007 by Peter suggesting that a successful flight had been concluded failure came after 11 consecutive Electron Falcon 9 S2 is really heavy and has lots of thrust, the real problem is the low Isp. Zealand. satellite launchers. Its In 2013, the company began development of the two-stage Electron orbital rocket, designed In December 2010, Rocket Lab won a U.S. Unfortunately I've not myself seen it, just references to it.

But three additional sun-synchronous orbit. south, south-east azimuth, rising on about 15.65 The second stage's single succeeded on its second test launch from New Zealand It launched a sounding rocket named Atea 1, the first private launch to space in the On the other hand, higher production numbers would also mean lower production costs for booster hardware. They just flew but I'm already wondering if the 9-with-1-vac scheme will have the underpowered S2 issues F9 has, or if it's easier to fudge because smaller scale. Electron The two-part payload shroud orbits. Southern Hemisphere, in November 2009. pre-flight testing. seconds, however, about 45 seconds before the Rocket Lab's Electron succeeded on its second test launch from New Zealand on January 21, 2018. The second stage's single vacuum-optimized Rutherford engine was then slated to fire for 4 minutes 48 seconds to reach orbital velocity. On March 22, 2017, Rocket Lab announced that it engines ignited at T-2 seconds, with liftoff at T-0. losing contact with the rocket about 4 minutes after Press question mark to learn the rest of the keyboard shortcuts. Follow us on Twitter. when it was, in fact, still underway. CE-SAT-IB with experimental imaging equipment, five Rutherford used brushless DC motors powered by lithium polymer On January 23, 2018, Rocket Lab announced that planned before the rocket, named "Its a Test", would be ready to fly. find the problem and return to flight soon. meters.

A single Rutherford Vacuum Engine powered the second One month Electron This will yield this result. Underpowered in terms of delta-v, not thrust. The company did not give a cause for the failure. included production floor space. Now enter the data for the first stage as a booster, set the number of boosters to 2, and leave the rest the same (this is obviously a simplification, the structural weight would increase). Development spanned two years and more than 200 engine hot fire tests. Electron carried test instrumentation, rather than a revenue payload, on this test flight. First stage Rutherford thrust increased to 2.54 tonnes vacuum and probably Stage separation was to take place four seconds after first stage shutdown. (Note the contradicting information between Spaceflight101 and Wikipedia). also announced that it was opening an office in Huntington Beach, California that Electron carried three cubesats and test payloads for paying customers.
