A new harvest of vegetables in space!

Notice that this research is a partnership of the Russians and an American university. NASA is not included. When I wrote about this subject for Air & Space a few years ago, the American researcher explained that there was too much bureaucracy working with NASA. Moreover, the Russians were much more knowledgeable about crop research in space, as they had been doing it for decades already on their Salyut and Mir stations.

What life has been like for one engineer who works at SpaceX.

What life has been like for one engineer who works at SpaceX.

Key quote:

According to Pearce, the best and the worst things about working for Musk are actually the same. “He doesn’t feel the need to make reasonable requests,” Pearce says. “The whole idea of SpaceX is not reasonable. The idea that a dot-com millionaire could take [US] $100 million and start a rocket company that within 13 years would be taking supplies to the International Space Station, that’s on track to take crew to the International Space Station — that’s not reasonable.”

But SpaceX did it.

In celebration of the tenth anniversary of Opportunity’s landing on Mars, the journal Science publishes a special section of the newest findings from Mars.

In celebration of the tenth anniversary of Opportunity’s landing on Mars, the journal Science has published a special section of the newest findings from Mars.

The main conclusion of all this research is that Mars was once potentially habitable, though there is no evidence so far to show that anything actually inhabited it. The data obtained however is now giving scientists clues on the best places to look for the remains of that ancient life, should it exist.

Virgin Galactic today announced the successful testing of their own new rocket engine.

The competition heats up: Virgin Galactic today announced the successful testing of their own new rocket engine.

Virgin Galactic, the world’s first commercial spaceline, announced today that it has reached a significant milestone in the testing of a new family of liquid rocket engines for LauncherOne, the company’s small satellite launch vehicle. As part of a rapid development program, Virgin Galactic has now hot-fired both a 3,500 lbf thrust rocket engine and a 47,500 lbf thrust rocket engine, called the “NewtonOne” and “NewtonTwo” respectively. Further, the NewtonOne engine has successfully completed a full-mission duty cycle on the test stand, firing for the five-minute duration expected of the upper stage engine on a typical flight to orbit. These tests are being conducted on two new state-of-the-art test stands that the team designed, assembled and installed internally. [emphasis mine]

Though they say that these engines are for their orbital rocket, not SpaceShipTwo, I find it interesting that their development was in-house, not by Scaled Composites which has so far been building everything for Virgin Galactic. Moreover, note the highlighted words, “rapid development program.” Though you should never be leisurely about this stuff in order to compete, giving this particular title to this engine program suggests they are in a particular hurry to develop it.

Both factoids suggest again that they are not happy with the performance of the hybrid engines Scaled Composites built for them, under their direction, and are now working hard to replace them.

Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.

3:57 pm

Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.

[Rosetta] woke yesterday as planned, to the relief of ESA scientists – but the signal it sent home to confirm it was awake reached Earth late, fraying the nerves of some mission controllers in the meantime. Due to call at 1745 GMT, Rosetta did not announce its revival until 1818. Fifteen minutes could be explained because the spacecraft’s computer checked the on-board clock only every quarter of an hour. The additional 18 minutes, however, was a mystery.

Now, the telemetry has shown that soon after Rosetta’s first revival sequence had started, the on-board computer automatically rebooted and the sequence started again, causing 18 minutes of delay.

It seems all is well now, though the engineers plan to spend some time pinpointing the cause of the reboot.

A donut-sized rock suddenly appears in front of the Mars rover Opportunity.

A donut-sized rock suddenly appears in front of the Mars rover Opportunity.

NASA announced the discovery of the rock at an event at Caltech in Pasadena this past Thursday night, dubbing the rock “Pinnacle Island.” “It’s about the size of a jelly doughnut,” NASA Mars Exploration Rover lead scientist Steve Squyres told Discovery News. “It was a total surprise, we were like ‘wait a second, that wasn’t there before, it can’t be right. Oh my god! It wasn’t there before!’ We were absolutely startled.”

If you want to see the inside of NASA’s gigantic Vehicle Assembly Building (VAB), you better hurry. Tours cease in February.

If you want to see the inside of NASA’s gigantic Vehicle Assembly Building (VAB), you better hurry. Tours cease in February.

Tours into the VAB have only occurred during gaps in the American space effort. I was lucky to visit Florida back in 1977, after the end of the Apollo program and before the start of the shuttle program, so my tour went inside the VAB. For the last few years, since the shuttle’s retirement, interior tours resumed.

The tour is worth it. If you can find the time and money, get down there now!

The European Space Agency has now released its first cost estimates for upgrading and replacing its Ariane 5 rocket.

The European Space Agency has now released its first cost estimates for upgrading and replacing its Ariane 5 rocket.

Europe needs to find about 1 billion euros ($1.35 billion) to complete development of an upgrade to its current Ariane 5 heavy-lift rocket, which would fly in 2018 and be capable of lifting satellites weighing 11,000 kilograms into geostationary transfer orbit, European Space Agency Director General Jean-Jacques Dordain said Jan. 17. The Ariane 5 upgrade, called Ariane 5 ME, will be on the table for ESA governments to decide, alongside the new Ariane 6 rocket, at a meeting scheduled for December in Luxembourg.

In a press briefing in Paris, Dordain said it is too early to say how much Ariane 6 will cost to develop. Government and industry estimates have ranged between 3 billion and 4 billion euros, with an inaugural flight in 2021.

As Doug Messier notes in his worthwhile analysis of these numbers, “Europe is in deep trouble.” From a customer’s perspective, these new rockets won’t fly (pun intended). The cost is too high and the development time too long. By the time they get both Ariane 5 and Ariane 6 ready for launch they will be obsolete and overpriced, when compared to the rocket’s that will already be available from their competitors.

Scaled Composites did an engine test today in Mojave of an alternative engine for SpaceShipTwo.

The competition heats up: Scaled Composites did an engine test today in Mojave of an alternative engine for SpaceShipTwo.

In this case, the company is even competing with itself, in that its first engine design is now in competition with another engine design. Considering the rumors about problems with that first design, I suspect the new design is probably winning.

An outline of Dream Chaser’s test flight schedule for the next three years, leading to its first crewed flight in 2017.

An outline of Dream Chaser’s test flight schedule for the next three years, leading to its first crewed flight in 2017.

The article makes a big deal about Sierra Nevada’s completion of a NASA paperwork milestone, but to me the aggressive flight schedule is more interesting, including news that the engineering vehicle used in the test flight in October was not damaged in landing so badly it could no longer be used.

The Dream Chaser Engineering Test Article (ETA) has since arrived back in her home port in Colorado, following her eventful exploits in California. Despite a red-faced landing for the baby orbiter, she earned her wings during an automated free flight over the famous Edwards Air Force Base, a flight that was perfectly executed, per the objectives of the Commercial Crew check list. The vehicle will now enjoy a period of outfitting and upgrading, preparing her for one or two more flights – listed as ALT-1 and ALT-2 – beginning later this year. Both will once again be conducted at the Dryden Flight Research Center in California.

The ETA will never taste the coldness of space, with her role not unlike that of Shuttle Enterprise, a pathfinder vehicle used to safely refine the final part of the mission for the vehicles that will follow in her footsteps. The Dream Chaser that will launch into orbit will be called the Orbital Test Vehicle (OTV), which is currently undergoing construction at the Michoud Assembly Facility (MAF). Debuting atop of the United Launch Alliance (ULA) Atlas V, the OFT-1 (Orbital Test Flight -1) is scheduled to take place in late 2016. This flight will be automated, testing the entire Dream Chaser system, prior to the crewed OFT-2 mission in early 2017. [emphasis mine]

I think I will up my bet from yesterday. I am now willing to bet that all of the commercial crew spacecraft chosen by NASA to complete construction will fly their privately built manned spacecraft with crew before NASA flies its first unmanned test flight of Orion/SLS.

A cheaper Japanese launch vehicle is scheduled to launch next month.

A cheaper Japanese launch vehicle is scheduled to launch next month.

The story is actually not very informative. What is interesting is the spin of the article: Japan’s rockets are getting cheaper! This suggests to me that the pressure brought to bear by SpaceX’s lower prices is being felt quite strongly.

We really don’t know if this Japanese rocket is cheaper to launch. What we do know is that, for the first time in decades, Japan feels compelled to use that sales pitch to sell its rockets. Isn’t competition great?

NASA’s first test flight of both the Orion capsule and the heavy-lift SLS rocket in 2017 might be delayed because of design problems with the European-built service module.

9:29 am

I am shocked, shocked! NASA’s first test flight of both the Orion capsule and the heavy-lift SLS rocket in 2017 might be delayed because of design problems with the European-built service module.

Overweight and struggling with design delays, the European-built service module for the Orion crew exploration vehicle may not be ready for a much-anticipated test flight by the end of 2017. The preliminary design review for the Orion spacecraft’s critical engine and power element is now on track for May after a six-month delay to contend with weight issues, according to Thomas Reiter, director of the European Space Agency’s human spaceflight and operations programs.

I am willing to bet that SpaceX will put astronauts in space on Dragonrider before this unmanned SLS flight occurs.

SpaceX has signed a contract with a Japanese commercial satellite company.

8:34 am

The competition heats up: SpaceX has signed a contract with a Japanese commercial satellite company.

The story was first reported on Friday, but I was busy this weekend and forgot to post it. Key quote:

The launch contract award for JCSAT 14, a communications satellite owned by Tokyo-based SKY Perfect JSAT Corp., adds another mission to SpaceX’s backlog, which stands at nearly 50 missions worth nearly $5 billion, according to a company press kit.

As SpaceX rolls these missions out and the money rolls in, it will insure the likelihood that they will build the Falcon Heavy as promised. And when they do, they will have created a heavy lift rocket and done it for pennies, compared to the costs spent on numerous government projects attempting to do the same.
