Larry Page told me, a little over two years ago, that he wanted to see us crash at least five of these scale versions of the energy kite. Obviously he wants us to be safe and we work very hard to be safe in everything that we do. What he meant by that was that he wanted to see us push ourselves to learn as fast as possible and though the learning from the crashing itself would be close to zero, he was pointing out that if you aren’t failing, if you aren’t breaking your experimental equipment at least occasionally, you could be learning faster.
Facing significant budgetary pressures, the Russian space agency, Roscosmos, has indefinitely postponed its ambitious effort to develop a super-heavy rocket to rival NASA's next-generation Space Launch System, SLS. Instead, Russia will focus on radical upgrades of its brand-new but smaller Angara-5 rocket which had its inaugural flight in Dec. 2014, the agency's Scientific and Technical Council, NTS, decided on Thursday, Mar. 12.
For Russia's space industry, it appears that these budgetary pressures have been a blessing in disguise. Rather than waste billions on an inefficient rocket for which there is no commercial demand — as NASA is doing with SLS (under orders from a wasteful Congress) — they will instead work on further upgrades of Angara, much like SpaceX has done with its Falcon family of rockets. This will cost far less, is very efficient, and provides them a better chance to compete for commercial launches that can help pay for it all. And best of all, it offers them the least costly path to future interplanetary missions, which means they might actually be able to make those missions happen. To quote the article again:
By switching upper stages of the existing Angara from kerosene to the more potent hydrogen fuel, engineers might be able to boost the rocket's payload from current 25 tons to 35 tons for missions to the low Earth orbit. According to Roscosmos, Angara-A5V could be used for piloted missions to the vicinity of the Moon and to its surface.
In a sense, the race is now on between Angara-A5V and Falcon Heavy.
