SpaceX schedules its next Dragon launch

The competition heats up: After delaying the launch to inspect its rockets for a suspected helium leak, SpaceX has now scheduled the next Dragon cargo mission to ISS for no earlier than April 13.

They will once again try to land their first stage during that launch. Also, the SpaceX schedule also lists a commercial launch later in April and the first launch abort test of Dragon in May.

A photo tour of Vandenberg Air Force Base

Yesterday, as part of my visit to Vandenberg Air Force Base to give a space history lecture to the local section of the American Institute of Aeronautics and Astronautics, I was given a short tour of these west coast launch facilities. While Kennedy is used for launches that circle the equator, Vandenberg, with its southern-facing coast, launches rockets that head south over the ocean for a polar orbit.

We only had time to go inside one launchpad, where unfortunately I was not permitted to take pictures. However, the images I did get will give you a reasonable sense of the layout for this spaceport, which is increasingly becoming a spaceport for private launch companies like ULA and SpaceX. Though the bulk of business for both companies here might be military and government payloads, the future is still going to include a lot of private payloads. The images also help to highlight the differences between these two companies, as well as some past history, as one of these launchpads was once intended for the space shuttle, though never used for that purpose.

Russia abandons super-rocket designed to compete with SLS

The competition heats up: Russia has decided to abandon an expensive attempt to build an SLS-like super-rocket and will instead focus on incremental development of its smaller but less costly Angara rocket.

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. It shall be quite exciting to watch this competition unfold between big government and private enterprise over the next few decades.

NASA schedules commercial manned demo missions to ISS

The competition heats up: NASA has now added to its ISS schedule the planned launch dates for the first demo missions of SpaceX’s and Boeing’s privately built manned capsules.

For Boeing, its CST-100 will first launch on an uncrewed test flight to the Station via the “Boe-OFT” mission in Apr, 2017 – on a 30 days mission, ending with a parachute assisted return. Should all go to place, the second mission will involve a crew – yet to be selected – on a mission designated “Boe-CFT”, launching in July, 2017, on a 14 day mission to the ISS.

The [planning] dates show SpaceX to be the most advanced in the Commercial Crew path, with their projected test flight dates currently set to win the honor of being the first Commercial Crew vehicle to arrive at the orbital outpost. That first Dragon 2 mission, designated “SpX-DM1″, has a December, 2016 launch date, ahead of a 30 day mission – most of which will be docked to the ISS – ending with a parachute assisted landing in the Pacific ocean. This would be followed by “SpX-DM2″, a crewed flight, launching in April of 2017, on a 14 day mission. This would mark the first time astronauts have launched from American soil on a US built spacecraft since Atlantis’ STS-135 mission in 2011.

American manned space exploration should begin to get very exciting in the next two years, with multiple companies now capable of putting humans in space.

SpaceX has another successful commercial launch

The competition heats up: SpaceX’s Falcon 9 rocket successfully launched its first two-satellite payload to geosynchronouse orbit on Sunday.

The satellites were unusual in that they both have replaced all their chemical engines with ion engines, thus saving weight and cost.

While the satellites will need six to seven times longer to reach the desired orbit, the cost savings is enormous. “The advantage of that, of course, is you don’t carry liquid chemical fuel, which is very heavy,” Betaharon said. “This particular satellite, each of them weigh around 2,000 kilograms. Typically, if you get a satellite like that from other manufacturers, or even from Boeing using chemical propulsion, they would weigh something around 3,500 to 4,000 kilograms, or in some cases maybe more. That’s why, because it’s lower mass, we managed to put two of them on one rocket, which right away reduces your launch costs in half.”

When ABS and Eutelsat signed up for Falcon 9 launch services several years ago, the rocket cost about $60 million. “We paid under $30 million for each satellite, which is almost unheard of,” Betaharon said.

More information about the new satellite designs can be found here.

Nonetheless, the combined weight of the two satellites plus the need to get them to geosynchronous orbit forced SpaceX to forgo another attempt to land its first stage vertical. The rocket needed the fuel to get the satellites where they had to go.

A dozen launches for Arianespace in 2015?

The competition heats up: Arianespace’s launch manifest for 2015 predicts a busy year, with a hoped for pace of one launch per month.

What I like most in the article however is what this paragraph says:

The launch provider won nine contracts for geostationary satellites in 2014, and eight of them are the right size to ride in the Ariane 5’s lower berth, [said Stephane Israel, Arianespace’s chairman and CEO] in an interview with Spaceflight Now.

SpaceX has emerged as the chief rival to the veteran French-based launch company, which started the commercial launch business when it was founded in 1980. SpaceX and Arianespace cinched the same number of commercial launch contracts last year. Partly in response to SpaceX’s bargain prices and partly as an initiative to ensure the Ariane 5 has a steady balance of heavier and lighter payloads, Arianespace cut prices for customers with smaller satellites. [emphasis mine]

I love how competition has lowered costs while simultaneously increasing the launch rate for multiple companies. Before SpaceX arrived to challenge established companies like Arianespace the accepted wisdom in the launch industry was that it was foolish to have more rockets capable of launching at lower costs, because there simply wasn’t enough business to justify it. You’d supposedly end up with idle facilities costing money with no payloads to launch. I always thought that theory was hogwash. Elon Musk and SpaceX have definitely proven it so.

Another Falcon 9 launch success

The competition heats up: A Falcon 9 rocket today successfully put a NASA solar observation satellite into orbit.

They have also said that they have achieved splashdown of the first stage, though no details yet on how soft that splashdown was.

Update: SpaceX reports that “the first stage successfully soft landed in the Atlantic Ocean within 10 meters of its target. The vehicle was nicely vertical and the data captured during this test suggests a high probability of being able to land the stage on the drone ship in better weather.”

No barge landing attempt today for Falcon 9

Because of high seas SpaceX will not attempt to land its Falcon 9 first stage on its floating barge today.

The drone ship was designed to operate in all but the most extreme weather. We are experiencing just such weather in the Atlantic with waves reaching up to three stories in height crashing over the decks. Also, only three of the drone ship’s four engines are functioning, making station-keeping in the face of such wave action extremely difficult.

They will still attempt a soft splashdown of the first stage in the ocean.

Though this kind of repeated soft splashdown test is essential to prove their ability to bring the first stage down safely, it certainly isn’t as exciting as landing the first stage on a barge. Nonetheless, in previous attempts they have been unable to get really good video of the soft splashdown. Maybe they will do better this time, though the high seas suggest it won’t be easy.
