MAVEN enters Mars orbit

7:25 pm

Upon completion of its engine burn this evening at 10:10 pm (eastern), MAVEN successfully entered Mars orbit.

Stephen Clark’s status updates on Spaceflight Now were accurate, informative, and right on the money. The live telecast on NASA-TV was confusing, idiotic, distracting, and uninformed. They never once announced when the engine burn had started, ignored the reactions of the people in the control room when they cheered some important event, and spent a lot of time discussing facts that were irrelevant to this event, which is “Will MAVEN achieve orbit!?” Worst of all, the male “anchor” was clearly ignorant of the mission while the female “anchor” spoke in a sing-song manner as if her audience were kindergarten toddlers who needed careful herding. All in all, it was embarrassing to watch.

They did manage to shut up just in time to catch the announcement from mission control that telemetry had confirmed that MAVEN had reached orbit. They then went back to chattering about irrelevant stuff. As I said, embarrassing.

India inks space deal with China

10:06 am

The competition heats up: India has signed a cooperative agreement with China to work together on several space projects.

Asked about the areas of focus, [Isro chairman K Radhakrishnan] said: “Right now, broadly speaking, it will be natural disasters and remote sensing, which are natural choices. But by March-April 2015, the joint working team would have prepared a roadmap, chalking out various options and opportunities for concentrated efforts in space exploration.”

This article is among a lot of articles from India this week about space and the upcoming orbital insertion of their Mars Orbiter Mangalyaan. As I’ve said repeatedly, this emerging prosperous and capitalist nation is space happy!

Also, when you click on the link make sure you scroll down to read the secondary sidebar piece at the bottom titled “After Mars, Kathakali beckons Isro chief.” There they describe the other culture interests of the head of India’s space agency, and how he plans to spend his time after he steps down in December. It will give you a flavor of India’s culture and how it differs from ours, even as it strives to emulate us.

Falcon 9 launch puts Dragon in orbit

11:03 pm

The competition heats up: SpaceX’s Falcon 9 rocket has successfully put its fifth Dragon cargo freighter into orbit, with a docking at ISS scheduled for Tuesday.

Spaceflight Now’s status update above also noted that this is the 13th launch of a Falcon 9 rocket since 2010. All these flights have successfully put their primary payloads into orbit as promised, an amazing track record for a new rocket built by a new company only in existence for less than a decade.

The next week in space

2:09 pm

For the next week there are going to be a number of important events that will determine the success or failure of a number of important space missions. I thought I’d lay out the schedule in a quick post, just to make it clear.

  • Falcon 9 launch: SpaceX is hoping to launch its Dragon capsule to ISS tonight at 2:14 am (eastern). If they are successful, it will be the fourth Falcon 9 launch since July 14. That is a very fast-paced launch schedule, as good as any other launch company’s, and more evidence that SpaceX is an effective competitor in the resurgent launch market.
  • Mavin orbital insertion: NASA hopes to place this Mars mission into orbit on Sunday at around 9:50 pm (eastern).
  • India’s Mars Orbiter Mission (MOM), also known as Mangalyaan: There are two important events this week for this mission. First, on Monday, September 22, engineers will do a test firing of the spacecraft’s engine, which has been inactive for the last several months during its cruise to Mars. If that firing is successful, they will do the orbital insertion burn on Wednesday, September 24.

So, stay tuned this week for some fun stuff. And as I’ve been saying, this is only the beginning.

Extending ISS to 2024

10:01 am

An inspector general report released today has outlined some issues that NASA needs to address in order to keep ISS operational through 2024.

In this audit, the Office of Inspector General (OIG) found that while NASA has identified no major obstacles to extending ISS operations to 2024, it must address several areas of risk to ensure continued safe operations. Specifically, the ISS faces a risk of insufficient power generation due in part to faster-than-expected degradation of its solar arrays. Second, although most replacement parts have proven more reliable than expected, sudden failures of key hardware have occurred requiring unplanned space walks for repair or replacement. Third, with the retirement of the Space Shuttle fleet NASA has a limited capacity to transport several large replacement parts to the Station should they be needed. While the ISS Program is actively working to mitigate these risks, anticipating the correct amount of replacement parts and transporting them to the ISS present major challenges to extending Station operations 10 or more years beyond its original expected service life.

The report also noted concerns about the budget and the lack of commitment from NASA’s international partners.

Dawn’s arrival at Ceres delayed one month

5:12 pm

Though engineers have solved the problems caused when a radiation blast disabled Dawn’s ion engine and put it into safe mode for a week, the fix will cause a one month delay in its arrival at the asteroid Ceres.

Controllers discovered Dawn was in safe mode Sept. 11 after radiation disabled its ion engine, which uses electrical fields to “push” the spacecraft along. The radiation stopped all engine thrusting activities. The thrusting resumed Monday (Sept. 15) after controllers identified and fixed the problem, but then they found another anomaly troubling the spacecraft.

Dawn’s main antenna was also disabled, forcing the spacecraft to send signals to Earth (a 53-minute roundtrip by light speed) through a weaker secondary antenna and slowing communications. The cause of this problem hasn’t been figured out yet, but controllers suspect radiation affected the computer’s software. A computer reset has solved the issue, NASA added. The spacecraft is now functioning normally.

Blue Origin to build rocket engine for Atlas 5

4:36 pm

The competition heats up: Jeff Bezos’s company Blue Origin has signed a contract with the United Launch Alliance to build a rocket engine for the Atlas 5 rocket so that it will no longer have to depend on Russian engines.

Neither executive [of either company] would discuss a dollar figure, although it’s likely somewhat less than $1 billion. Bruno said a typical liquid-fueled rocket engine takes seven years and $1 billion to develop, but Blue Origin is already several years along on the BE-4. Bruno said the engine could be ready within four years to serve as the main engine on the company’s Atlas V rockets.

This is excellent news, because it shows that ULA is being pro-active in solving this problem, rather then waiting for Congress to act.

Another contest where you can win a ticket to space

9:39 am

Spaceship Earth Grants (SEG) has launched a contest where it will give away one space flight ticket to fly on any available launch service for every 50,000 applications it receives.

The winner (or winners) will receive a trip aboard a spaceflight provider flight available at the time of the award announcement. In other words, should the likes of space tourism companies like Virgin Galactic or Space Adventures be capable of offering trips into space at the time, then the winning candidate would be booked aboard one of their flights. Subject, of course, to availability and the various restrictions one or all of these companies may impose, along with the rider that no promise is made to be able to fly on a particular carrier.

Be warned however, the application is not free. SEG will charge you from $15 to $90, the amount “dependent upon the relative wealth of the nation in which you live.”

NASA has chosen Boeing and SpaceX to build manned spacecraft to ferry crews to ISS

1:12 pm

The competition heats up: NASA has made a decision and has chosen two companies to ferry astronauts to and from ISS, and those companies are Boeing and SpaceX.

I am watching the press conference on NASA television. Some quick details from NASA here.

This is a reasonable political and economic decision. It confirms that SpaceX is ready to go and gives the company the opportunity to finish the job, while also giving Boeing the chance to show that it can compete while also giving that pork to congressional districts.

Some details: After NASA has certified that each company has successfully built its spacecraft they will have then fly anywhere from four to six missions. The certification process will be step-by-step, similar to the methods used in the cargo contracts, and will involve five milestones. They will be paid incrementally as they meet these milestones.

One milestone will be a manned flight to ISS, with one NASA astronaut on board.

One more detail. Boeing will receive $4.2 billion while SpaceX will get $2.6 billion. These awards were based on what the companies proposed and requested.

I will have more to say about this tonight on Coast to Coast, as well as on the John Batchelor show.

Air Force to decide SpaceX certification on December 1

12:39 pm

The competition heats up: The Air Force has set December 1 for its deadline for certifying SpaceX as qualified to launch military satellites.

“I root for SpaceX to come into the competition,” Gen. John Hyten, head of Air Force Space Command, said during a speech Tuesday at the Air Force Association’s annual conference. But he warned that the company may not be ready in time. “The most important thing for this nation is assured access to space that works all the time,” he said. “That’s why the certification for SpaceX, hopefully by Dec. 1, is a big event. But if they’re not ready on Dec. 1, we have to stand up and say that, and that’s going to be difficult because I want competition.”

It sounds like the Air Force is setting this date as when it will decide one way or the other, regardless of anything SpaceX has done. I also suspect that, because of politics, this decision will hinge on what NASA decides today concerning its commercial crew contract.

Management problems at NASA’s asteroid hunting program

11:15 pm

An inspector general report today criticized NASA’s program to find potentially hazardous asteroids, finding it disorganized and poorly managed.

The report faulted the NEO Program’s lack of structure, and said its resources are inadequate for handling its growing agenda. In addition to the program’s Washington-based executive, Lindley Johnson, NASA funding goes to support six employees at the Minor Planet Center in Massachusetts and six more at the Jet Propulsion Laboratory in California, the inspector general’s office said.

The report said the program’s executive fell short when it came to overseeing progress in the asteroid-tracking effort. What’s more, there were no formal partnerships with the Defense Department or the National Science Foundation, or with international space agencies. Those groups could make significant contributions to the effort, the report said.

I do not doubt that this program has management problems. What government agency today doesn’t? And any that are managed well are the exception to the rule. However, the report’s conclusion that “resources are inadequate for handling its growing agenda” is typical Washington-speak for “Give us more money!” which almost never solves the management problems that made the program a failure in the first place.

No first stage landing attempt on next Falcon 9/Dragon launch

3:44 am

SpaceX has decided not to attempt a soft splashdown of the Falcon 9 first stage during Saturday’s launch of the Dragon capsule to ISS.

In a change of plans, the Falcon 9 booster stage set to launch Saturday will not carry landing legs, according to Hannah Post, a SpaceX spokesperson. She said SpaceX does not plan to attempt a water landing of the first stage after its job during launch is completed.

SpaceX initially planned to program the rocket’s first stage to fly back to Earth after completing its work to boost the Dragon spacecraft off the launch pad, but engineers swapped out the Falcon 9 booster with a first stage originally assigned to another flight, officials said.

The reason for the changeout was not disclosed.

I suspect this decision is in connection with the Falcon 9R failure last month, but admit I am speculating with no inside knowledge.

I should also note that if Saturday’s launch goes as planned, it will set a new SpaceX record for the fastest turn-around between launches, less than two weeks. If they succeed, I think they will prove once and for all to most of their remaining naysayers that they are a serious, reliable, and well-run launch company.

Philae’s landing site chosen

3:32 am

Philae's primary landing site

The Rosetta science team has chosen the primary landing site on Comet 67P/C-G for its Philae probe.

Site J is on the ‘head’ of the comet, an irregular shaped world that is just over 4 km across at its widest point. The decision to select Site J as the primary site was unanimous. The backup, Site C, is located on the ‘body’ of the comet. The 100 kg lander is planned to reach the surface on 11 November, where it will perform indepth measurements to characterise the nucleus in situ, in a totally unprecedented way.

This site is, located in the outside center of the nucleus’s smaller lobe, was picked unanimously because it appears to be the easiest to reach while also providing good science.

The descent to the comet is passive and it is only possible to predict that the landing point will place within a ‘landing ellipse’ typically a few hundred metres in size.

A one square kilometre area was assessed for each candidate site. At Site J, the majority of slopes are less than 30º relative to the local vertical, reducing the chances of Philae toppling over during touchdown. Site J also appears to have relatively few boulders, and receives sufficient daily illumination to recharge Philae and continue science operations on the surface beyond the initial battery-powered phase.

Provisional assessment of the trajectory to Site J found that the descent time of Philae to the surface would be about seven hours, a length that does not compromise the on-comet observations by using up too much of the battery during the descent.

I have put a close-up of the landing site below the fold.

The competition in space continues to heat up

9:10 am

Two news stories today indicate that things are going to get increasingly interesting in the exploration of space in the coming years.

First there is this story from Joe Abbott of the Waco Tribune, who routinely reports on SpaceX news because their McGregor test facility is nearby. In it Abbott reports that SpaceX has scheduled its next Dragon supply mission to ISS for no early than September 20.

This news item however is not Abbott’s most interesting news. He also notes several twitter reports coming out a commercial satellite conference in Paris that indicate that SpaceX has closed 9 deals, including several more for its as yet unflown Falcon Heavy.

But even that is not the most interesting news. Abbott also reports that a replacement for the destroyed Falcon 9R test vehicle will be shipped to McGregor for testing in less than two months. Considering how long it takes governments to build and fly test vehicles, getting this replacement in shape for flight mere months after the failure a few weeks ago is quite impressive.

But even that was not Abbott’s most interesting SpaceX news item. » Read more

An update on the status of NASA manned commercial competition

3:25 pm

Jason Davis at the Planetary Society blog has put together an excellent summary of the status for all three companies competing for NASA’s contract to ferry astronauts to and from ISS.

Key paragraph:

From a quantitative standpoint, Boeing is the leader. Since the first quarter of 2013, the company has been ahead in percentage of milestones completed and percentage of funding awarded. Plus, there’s the simple fact that they’ve finished all of their milestones, while SpaceX and Sierra Nevada asked for extensions. But from a qualitative standpoint, things are less straightforward. SpaceX has already proven they can fly missions to the ISS. And they’re the only CCiCap participant with a pad abort test and an in-flight abort test among their milestones.

It is very clear just looking at the actual milestones that what Boeing has done so far is not that impressive. Almost everything on their list is a paperwork review, not construction or testing of actual hardware. Meanwhile, SpaceX and Sierra Nevada are building and testing spacecraft. That they have not yet completed their milestones is hardly a big deal in this context.

Playing with today’s Rosetta image of Comet 67P/C-G

12:04 am

Adjusted comet image

In releasing Wednesday’s image of Comet 67P/C-G, the Rosetta science team suggested that readers download it and play with the brightness and contrast settings to bring out some interesting details.

[I]f you adjust the contrast of the image you will see that there is a lot of ‘noise’ in the background. Some of this is simply detector noise and cosmic rays, but there seem to be a few bright objects that may be dust/ice particles between Rosetta and the comet.

In previous NAVCAM and OSIRIS images, we’ve already seen jets of gas laced with dust streaming away from the comet, and the instruments COSIMA and GIADA have started detecting dust, so it would be no surprise if these objects were also found to originate from the comet. In any case, it is a phenomenon that will clearly be studied in great detail at 67P/C-G over the coming weeks and months.

Another nice observation you might like to make while playing around with the contrast settings is that faint details can be brought out in the ‘neck’ region of 67P/C-G, which on first look is seemingly obscured by shadows. It appears as though the neck is being illuminated by the reflection of sunlight off the main body of the comet below.

The image on the left above is the image as released. The image on the right I have brightened considerably to bring out additional details. As they noted, you can see topographical details in the shadowed neck area. Also, the entire nucleus seems to be surrounded by faint dust streaming away in all directions.

It is going to be a great deal of fun to watch this comet change over the next year as it makes its journey around the Sun.

Russia to match SpaceX launch prices

4:29 pm

The competition heats up: The head of Russia’s United Rocket and Space Corporation (URSC), which now controls that country’s entire space industry, said today that they intend to compete with SpaceX’s Falcon 9 much cheaper launch prices.

They intend to do it with both the Proton rocket as well as their new family of Angara rockets. The heavy version of Angara will allow them to compete with SpaceX’s Falcon Heavy, and in fact might even put more payload into orbit for less.

Curiosity to begin climbing

12:29 pm

Scientists have decided to begin Curiosity’s climb of Mount Sharp immediately rather than continue a planned traverse along the base of the mountain prior to heading uphill.

Curiosity’s trek up the mountain will begin with an examination of the mountain’s lower slopes. The rover is starting this process at an entry point near an outcrop called Pahrump Hills, rather than continuing on to the previously-planned, further entry point known as Murray Buttes. Both entry points lay along a boundary where the southern base layer of the mountain meets crater-floor deposits washed down from the crater’s northern rim.

The issues with Curiosity’s wheels also played a part in this decision.

Putin threatens management at Vostochny with criminal prosecution

8:47 am

In a statement today in the Russian press Vladimir Putin proposed initiating a criminal investigation into the management of the new Vostochny spaceport.

[Putin] admitted that “although the project is in the focus of our special attention, problems abound. … I will have to hand over some issues to law enforcement agencies to get them sorted out and clarified,” Putin said. Funding is provided regularly but the funding procedure itself needs special attention, he said, referring to “quasi and semi-criminal schemes”.

It appears that funds have not been used as efficiently as he likes and his solution is to threaten prosecution of those involved. This is becoming a standard Putin technique. He used it to guarantee his control over the Russian aerospace company Energia, and now he is using it here to guarantee the Vostochny project moves forward fast and efficiently.

Its use also illustrates the limitations of Russia’s top down approach to everything. Such threats can prevent corruption in a specific project, but that such treats are necessary so frequently points out how easily such corruption grows in a government-run centralized bureaucracy. We see it here in the U.S. as well. Take away the profit motive and private ownership and there remains nothing to naturally focus the efforts of management towards success and efficiency.

The first chemical analysis of Comet 67P/C-G’s coma

8:30 am

The Rosetta science team today released their first analysis of the chemical make-up of Comet 67P/C-G’s coma, finding that not surprisingly it is made up mostly of water, carbon monoxide, and carbon dioxide.

However, ROSINA [the instrument on Rosetta for doing this analysis] has made the surprising observation that the ratio between these species varies quite significantly, depending on where in the coma Rosetta is. Sometimes carbon monoxide is almost as abundant as water; sometimes it’s only around 10%. In addition, ROSINA has not only detected these main species already, but many of the expected minor ones, such as ammonia, methane, and methanol.

Europe’s satellite makers want Ariane 6

8:50 pm

Europe’s six biggest satellite makers have written Arianespace to demand that the company build its next generation Ariane 6 rocket by 2019 or face a significant loss of business.

Given the advent of electric propulsion and the dramatic launch-cost reduction offered by Space Exploration Technologies Corp., the operators say, the new Ariane 6 needs to be in service by 2019 or face the risk that Europe’s Arianespace launch consortium will be permanently sidelined. The letter was signed by six members of the European Satellite Operators Association. Signatories included the chief executives of Intelsat, SES, Eutelsat, Inmarsat, Hispasat and HellasSat.

This letter is clearly intended to help prod Arianespace into making a decision on whether to build a new rocket, Ariane 6, or upgrade Ariane 5. Right now the company’s partners have been unable to come to an agreement about what to do.

Another delay at Virgin Galactic

2:21 pm

In an interview with David Letterman this week, Richard Branson admitted that his first flight on SpaceShipTwo will not be in December 2014 but early next year.

Watch the interview at the link. It is very clear that Branson is getting uncomfortable with the situation. He has made these claims too many times without showing any results. Also note the incredible ignorance exhibited by Letterman. A good interviewer has to ask some basic questions, but a good interviewer also needs to have a basic understanding of the subject. Letterman shows us here that he doesn’t know squat.
