  1. Soyuz telemetry graphs! Nice!
  2. The russian space industry has certainly suffered some setbacks. Proton grounding. Engine investigations. Funding cuts. Vostochny cost overruns. Angara development right alongside the Falcon9 paradigm shift. On the positive side, they still provide the only crewed access to ISS, rd-180s for atlas V, and entire soyuz vehicles for ESA. They still do supply runs to the ISS and GTO sat lifts with proton. But in 5 years time, things will be different. Barring global disasters/conflict, we are likely to see crewed LV alternatives for ISS, Vulcan and ITSy prelims, and Falcon 9 running a higher cadence. FH, Ariane 6 and possibly new vehicles from china and india. Interesting times.
  3. Atlas V 401 TDRS-M

    Launching in about 2hrs.
  4. It caught me by surprise. Feels like they are backpedalling a bit going for a cheap expendable. Maybe not. Single stick seems to be to way forward cost-wise. It cant compete with F9, even at $50M per launch...... Maybe its just cheaper, quicker to market and less risk than a new methane LV? GSE and pad will be simpler than for angara. The only major risk part looks like being the spacecraft itself.
  5. I don't know. May have to wait for some more info. This is all i could find on energia's website : Be aware they have reused the Soyuz-5 name from the methalox proposal. The wikipedia article has not been edited since march.
  6. 530t RD-170M first stage 2xRD-0124M second stage 15-16t to LEO. From RussianSpaceWeb : NSF comments (replys 34-39)
  7. from " Rocket Lab has completed an internal review of data from its May 25 test flight of its Electron rocket. The review found the launch had to be terminated due to an independent contractor’s ground equipment issue, rather than an issue with the rocket. Rocket Lab’s investigation board has identified the root causes and corrective actions. The Federal Aviation Administration, the primary body responsible for licensing the launch, has overseen Rocket Lab’s comprehensive investigation and will review the findings. Rocket Lab’s engineers have spent the last two months working through an extensive fault tree analysis to ensure all factors that may have influenced the outcome of the launch were thoroughly evaluated. The investigation involved the review of over 25,000 channels of data collected during the flight in addition to extensive testing at Rocket Lab facilities in California and New Zealand. Rocket Lab’s investigation team determined the launch, named ‘It’s a Test’, was terminated due to a data loss time out, which was caused by misconfiguration of telemetry equipment owned and operated by a third-party contractor who was supporting the launch from Rocket Lab’s Launch Complex 1. Four minutes into the flight, at an altitude of 224 km, the equipment lost contact with the rocket temporarily and, according to standard operating procedures, range safety officials terminated the flight. Data, including that from Rocket Lab’s own telemetry equipment, confirmed the rocket was following a nominal trajectory and the vehicle was performing as planned at the time of termination. “We have demonstrated Electron was following its nominal trajectory and was on course to reach orbit,” said Peter Beck, Rocket Lab CEO. “While it was disappointing to see the flight terminated in essence due to an incorrect tick box. We can say we tested nearly everything, including the flight termination system. We were delighted with the amount of data we were able to collect during an exceptional first test launch. Rocket Lab’s telemetry systems provided data verifying Electrons capabilities and providing us with high confidence ahead of our second test flight. The call to terminate a launch would be tough for anyone, and we appreciated the professionalism of the flight safety officials involved.” The telemetry data loss that led to the termination of the flight has been directly linked to a key piece of equipment responsible for translating radio signals into data used by safety officials to track the vehicle performance. It was discovered a contractor failed to enable forward error correction on this third-party device causing extensive corruption of received position data. The failure was first indicated by the fact that Rocket Lab’s own equipment did not suffer similar data loss during launch. Further confirmation of the cause was demonstrated when replaying raw radio-frequency data - recorded on launch day - through correctly configured equipment also resolved the problem. The fix for the issue is simple and corrective procedures have been put in place to prevent a similar issue in future. No major changes to the Electron launch vehicle hardware have been required and the company has authorized the production of four additional launch vehicles as it prepares for commercial operations ahead of the test flight program. Rocket Lab’s second Electron rocket, named ‘Still Testing’, is undergoing final checks and preparations ahead of being shipped to Rocket Lab Launch Complex 1 shortly. "

  13. Amateur rocket to orbit

    I figure there will be rutherford engine clones being worked on in just about every university aerospace shop on the planet. The kids working on this stuff will be keen to see their projects fly. And those designs and expertise will filter thru to the amateur space.
  14. Amateur rocket to orbit

    The engineering approach to amateur sub-orbitals : Wonder if he will roll out a methane (or just LNG) engine for better performance? Maybe change pressure-fed to electric turbopumps that are 3d printed? Then comes adding a 2nd stage to try for orbit.
