NASA’s Space Launch System, costing billions per year, will only make its second manned flight in 2025.

The competition cools off! NASA’s Space Launch System, costing billions per year, will only make its second manned flight in 2025.

SLS is to make its maiden flight in 2017, when it will carry an empty Orion crew capsule to near-Moon space and back. Another flight would follow in 2021 and, depending on factors both technical and political, could see a crew of astronauts travel to a captured asteroid NASA wants to redirect to a high lunar orbit using a yet-to-be-built robotic spacecraft.

Notionally, SLS would next fly in 2025, giving the rocket a launch rate of once every four years. NASA has been spending about $1.8 billion a year on SLS development, including construction of a rocket test stand in Mississippi, and associated launch infrastructure at the Kennedy Space Center in Florida. Add in the cost of the rocket’s companion crew capsule, the Lockheed Martin-built Orion, and the tab rises to nearly $3 billion a year. [emphasis mine]

At that launch rate, the NASA’s space effort is slower than China’s, which has a pace that I consider extremely tortoise-like.

But don’t worry, buckos! NASA will be keeping the seats warm in its thousands of government facilities, employing thousands of government workers doing little or nothing.

Arianespace will not be able to set its launch manifest for the remainder of this year until late July.

The competition heats up: Arianespace will not be able to set its launch manifest for the remainder of this year until late July.

The year’s third Ariane 5 mission is scheduled for launch in late July carrying the large Alphasat satellite for mobile satellite services operator Inmarsat of London and the European Space Agency (ESA); and India’s Insat-3D telecommunications satellite.

Beyond that, Israel said, it is unclear which commercial payloads will be placed on which of the two remaining Ariane 5 flights, scheduled for this fall, or what the Ariane 5 manifest looks like for 2014. A big question is whether Arianespace has any slots open in the Ariane 5 manifest in 2014 to accommodate new customers who want to switch to Ariane 5 because their selected vehicle is late.

This article not only suggests that Arianespace has more business than it can handle, it is also provides evidence that the company is scrambling to cut costs in order to compete.

A Russian Soyuz rocket successfully launched four commercial broadband satellites today for French Guiana.

The competition heats up: A Russian Soyuz rocket successfully launched four commercial broadband satellites today for French Guiana.

The constellation’s orbit is designed to provide high-bandwidth Internet links to land masses located between 45 degrees north and 45 degrees south of the equator, which means mainly the developing world.

An interesting historical note of this story is that

O3b and SES officials have said that the company has regulatory rights to sufficient spectrum to put as many as 120 satellites in the same unusual orbit. O3b is making use of radio spectrum originally won, following a long battle, by a U.S. company called Teledesic, which had envisioned more than 800 satellites to provide broadband links worldwide. Teledesic ceased operations before launching its satellites.

Teledesic was a $9 billion satellite constellation proposed by Bill Gates back in 1998. They only launched one satellite, Teledesic 1, which was a failure. That this project has essentially come back to life fifteen years later is most intriguing.

The Chinese astronauts have undocked from the Tiengong-1 space station and will return to Earth tomorrow.

The Chinese astronauts have undocked from the Tiengong-1 space station and will return to Earth tomorrow.

Following a separation from the Tiangong-1 at 7:05 a.m. Beijing Time, the manned Shenzhou-10 moved back to a point from where the spacecraft changed its orbit and flew around the target module. Under the command of ground-based professionals, Shenzhou-10 adjusted its flight gesture at a point behind Tiangong-1, and approached and rendezvoused with the target module.

The fly-around and rendezvous was apparently controlled by ground controllers, not the astronauts on board.

Two Russian astronauts completed a six-hour-plus spacewalk today, preparing the station for Russia’s science module.

Two Russian astronauts completed a six-hour-plus spacewalk today, preparing the station for Russia’s science module.

This science module is many years late, delayed due to Russia’s financial problems after the fall of the Soviet Union. That the Russians are finally about to launch it is another indication, like their recent Proton rocket launch successes, that there space program might be experiencing a resurgence.

Orbital Sciences is scrambling to find a reliable long term first stage engine for its Antares rocket.

Orbital Sciences is scrambling to find a reliable long term first stage engine for its Antares rocket.

The NK-33 engine that powered Antares’ first flight was built decades ago by Russia’s Kuznetsov Design Bureau and is no longer in production. Further, Orbital is uncertain about the quality of Aerojet’s remaining stockpile of 23 NK-33s, beyond those set aside for NASA’s CRS-1. Aerojet Rocketdyne is Orbital’s primary subcontractor and overhauls the old NK-33 engines into a configuration for Antares, dubbed AJ-26. Orbital officials say its only current alternative is the RD-180 engine made in Russia by NPO Energomash. But the United Launch Alliance (ULA), which operates the U.S. Air Force’s Atlas V and Delta IV fleets, holds exclusive rights in the U.S. to buy the RD-180.

Over the last four years, Orbital has inquired about purchasing the RD-180 from ULA, RD Amross and Energomash. “We could never get to first base on that,” says Michael Hamel, the company’s senior vice president of corporate strategy and development. Requests for support from the Air Force, Office of the Secretary of Defense and Congress were also met with silence, company officials say.

What I find disturbing about this story is the complete lack of effort by Orbital, Aerojet, or ULA to build their own engines. Even if new NK-33 engines are made by Aerojet, they will be manufactured in Russia, as are ULA’s engines. Why can’t they do what SpaceX has done and make their own engines?
