Lockheed Martin ready to build Orion?

6:08 pm

O joy! After more than a decade of design work, costing billions, Lockheed Martin now says it is ready to begin building the first Orion capsule for eventual launch only 8 years from now!

“The vast majority of Orion’s design is over, and now we will only change things when new requirements come into play,” said Michael Hawes, Lockheed Martin Orion vice president and program manager. “Considering the incredible complexity of this spacecraft, the team is very proud to have successfully completed the design review and is looking forward to seeing it fly.”

For those who don’t detect my sarcasm, I find this project more than absurd. Bush proposed Orion in 2004. Lockheed has been spending billions for years just designing it. In about six to eight years from now they might finally get one capsule completed for launch in 2023, almost two decades after it was first proposed.

Two decades to build one capsule! With a cost in the billions. Let these facts sink in for a bit and then ask yourself: Why are we spending money on this pork project that will never fly?

Worldview tests subscale prototype of its balloon and capsule

5:59 pm

The competition heats up: Worldview, the company planning to sell tickets for high-altitude tourist flights to the edge of space, successfully completed this weekend a test flight of a 10-percent scale prototype of its capsule and balloon.

The balloon reached an altitude just over 100,000 feet, just under 19 miles. The capsule then separated and landed safely using a parafoil. This success keeps them on schedule for their first commercial flights in 2017.

Pluto’s meandering canyons

8:52 am

canyons of Pluto

Cool image time! In scrolling through the new raw images downloaded from New Horizons today I came across an image, one of several, that showed what clearly appeared to be meandering canyons carved by flowing liquid.

To show it here, I have cropped it and reduced its size somewhat, highlighting the most interesting features. As you can see, the largest canyon not only appears to have a dark floor, it cuts right through an older crater. Smaller canyons do the same thing. In addition, many of the craters seem to be ponded with the same dark material that floors the canyons, while some of the smaller canyons show tributaries that come together, just like rivers. Are these flows of liquid nitrogen?

I eagerly await the conclusions of the scientists, who are probably only slightly less baffled by these features as I am.

Be sure and check out the full image, as well as the other raw images. The data continue to come in from New Horizons, but the science team is no longer under the same kind of public pressure to make announcements or hold press conferences. There are gems hidden there that are worth looking at, even if they are not as yet accompanied by any scientific analysis.

NASA to decide on 2nd cargo contracts Nov 5

9:40 am

The competition heats up: NASA will announce the two contract winners for its second round of ISS cargo contracts on November 5.

If it was up to me to pick the two winners from the four companies bidding, SpaceX, Boeing, Orbital ATK, and Sierra Nevada, I would go with Orbital ATK and Sierra Nevada. SpaceX and Boeing already have contracts to ferry crews to ISS with their Dragon and Starliner capsules. By picking Orbital ATK’s Cygnus capsule and Sierra Nevada’s Dream Chaser reusable mini-shuttle, NASA would then have four different ways to get payloads to ISS.

Sadly, the decision is not up to me. It is more likely NASA will pick SpaceX and Boeing. Boeing especially is likely to get picked because they are an established big player with lots of capital and influence.

A detailed update on the Falcon 9 return-to-flight

9:21 am

Link here. It appears that SpaceX hopes to complete the following launches in quick order::

1. November 24: First Falcon 9 upgrade launch: 11 Orbcomm low-orbit satellites
2. December 15: Last old Falcon 9 launch: Jason 3
3. December 27: Second Falcon 9 upgrade launch: SES-9 geosynchronous communications satellite
4. Early January: Third Falcon 9 upgrade launch: Dragon and the Bigelow BEAM inflatable module to ISS

All these dates are of course subject to delays. Launches 1 and 3 will definitely attempt vertical landings of the first stage on a barge.

The main point of the article above was to note that the SpaceX is now ready to do a full thrust test firing of the first stage that will be used in the November 24 launch, doing that test at its McGregor, Texas, test facility. As noted, “All Falcon stages pass through the Texas site, allowing them to be fired up and tested for any issues prior to continuing their journey to the launch site.” The article then described one case where the testing successfully spotted an issue that was fixed prior to launch.

I think this speaks volumes about the robustness of SpaceX’s manufacturing process. Their rockets are built in one place, shipped to another for testing, and then shipped to a third for launch. And all within mere weeks. This robustness also suggests that the rocket’s first stage will be able to withstand its vertical landing and be able to be reused, as planned.

The article also provides some further insights in why the company switched the SES-9 and Orbcomm launches.

Pluto in 3D

9:09 am

The New Horizons science team has released its first 3D image of the surface of Pluto.

You need red/blue stereo glasses to view it.

The image shows an ancient, heavily cratered region of Pluto, dotted with low hills and cut by deep fractures, which indicate extension of Pluto’s crust. Analysis of these stereo images shows that the steep fracture in the upper left of the image is about 1 mile (1.6 kilometers) deep, and the craters in the lower right part of the image are up to 1.3 miles (2.1 km) deep. Smallest visible details are about 0.4 miles (0.6 kilometers) across.

My impression of the image, using the glasses, makes me wonder if they have exaggerated the vertical depth so that it would stand out. The craters look more like pits than craters. And if they didn’t exaggerate the vertical depth, then that means that impacts on Pluto produce craters that are very different than those seen in the inner solar system.

Mysterious piece of space junk to hit Earth

8:34 am

A piece of unidentified space junk, discovered in a long elliptical orbit going out far beyond the Moon, has been calculated to hit the Earth over the Indian Ocean on November 13.

WT1190F was detected by the Catalina Sky Survey, a program aimed at discovering asteroids and comets that swing close to Earth. At first scientists didn’t know what to make of this weird body. But they quickly computed its trajectory, after collecting more observations and unearthing 2012 and 2013 sightings from telescope archives, says independent astronomy software developer Bill Gray, who has been working to track the debris with NASA’s Jet Propulsion Laboratory in Pasadena, California.

WT1190F travels a highly elliptical orbit, swinging out twice as far as the Earth-Moon distance, Gray says. Gray’s calculations show that it will hit the Earth at 6:20 UTC, falling about 65 kilometres off the southern tip of Sri Lanka. Much if not all of it will burn up in the atmosphere, but “I would not necessarily want to be going fishing directly underneath it,” Gray says.

What makes the object interesting is that they don’t know when it was launched or how it got in the orbit it is in. It could even be something from the Apollo lunar missions.

ULA prepares Atlas 5 for its third October launch

8:38 am

The competition heats up: ULA will attempt its third Atlas 5 launch in October, launching a new GPS satellite for the Air Force on October 30.

In the past ULA never packed its launches in this tightly. I suspect they are now doing so because of the competition from SpaceX. They need to show their customers, both commercial and the government, that they are a reliable launch provider. Launching three Atlas 5s in one month is one way to do it.

SpaceX Dragonfly test vehicle arrives in Texas

5:14 pm

The competition heats up: Dragonfly, SpaceX’s test capsule for testing vertical rocket landings, has arrived at their facility in McGregor, Texas.

DragonFly will be attached to a large crane, ahead of a series of test firings of its SuperDraco thrusters to set the stage towards the eventual goal of propulsive landings. The first test is set to take place in the next few weeks to kick start around two years of incremental testing.

Similar in concept to Grasshopper, Dragonfly is not an actual Dragon capsule, but a testbed for figuring out how to do vertical landings with a capsule, using thrusters.

SpaceX switches payloads for next launch

6:52 pm

The competition heats up: SpaceX has rearranged the payloads for its next two launches, delaying the SES-9 geosynchronous communications satellite launch until December to instead launch 11 Orbcomm low-orbit satellites in November.

Using the upgraded Falcon 9, this switch will give them more fuel to try a vertical landing of the first stage on this first launch. They will then try again on the second launch.

Fractures on Enceladus’s north pole

6:02 pm

Enceladus's North Pole

The Cassini science team has released the first image from Wednesday’s flyby of the Saturn moon Enceladus.

Scientists expected the north polar region of Enceladus to be heavily cratered, based on low-resolution images from the Voyager mission, but the new high-resolution Cassini images show a landscape of stark contrasts. “The northern regions are crisscrossed by a spidery network of gossamer-thin cracks that slice through the craters,” said Paul Helfenstein, a member of the Cassini imaging team at Cornell University, Ithaca, New York. “These thin cracks are ubiquitous on Enceladus, and now we see that they extend across the northern terrains as well.”

To see more you can browse the raw images here.

The next flyby later this month will be especially interesting as they will dip to within 30 miles of the surface.

More evidence of giant flash floods on Mars

9:45 am

Mangala Valles

A newly released image from ESA’s Mars Express orbiter shows that catastrophic flooding — caused by ice melted from volcanic activity — created the Mangala Valles channels on Mars.

The perspective image on the right shows the topography of the region, with low points indicated in blue and high points by red. The channel along the right side of the image is Mangala Valles itself, though you can also see additional flood channels to the left of it passing around and through a large crater whose floor now stands above the surrounding terrain caused by the erosion of the rim plus the deposit of sediment inside the crater during the flooding.

I have a soft spot for Mangala Valles. When it was first photographed by the first orbiter missions to Mars in the early 1970s I was struck by its river-like appearance and striking topography. I therefore placed my Martian colony here in one of my efforts at science fiction writing. I figured it a good location for colonization, as there would likely be water and, by roofing over the deep canyon, a colony could be built relatively easily.

Better locations on Mars have since been found, but the location still intrigues me.

Smallsat rocket launchers get NASA contracts

9:21 am

The competition heats up: NASA this week awarded contracts ranging from $4.7 to $6.9 million to three different smallsat launch companies.

The companies are Firefly Space Systems, Rocket Lab USA, and Virgin Galactic. The second is the company that just won the contract to put a privately-built lunar rover on the moon (part of the Google Lunar X-Prize).

In the past, cubesats and other small satellites could only afford to be secondary payloads on much larger rockets. Thus, they were at the mercy of the needs of the primary payload, often resulting in significant unplanned delays before launch. This in turn acted to discourage the development of smallsats. Now, with these private launch companies designed to service them exclusively the smallsat industry should start to boom.

Note also the low cost of these contracts. The small size of cubesats and the launchers designed for them means everything about them costs much less. Putting an unmanned probe into space is thus much more affordable.

Antares failure wipes out Aerojet’s 2nd quarter profits

9:07 am

The settlement between Orbital ATK and Aerojet Rocketdyne over the failure of an Aerojet Russian engine that failed during an Antares launch has wiped out Aerojet’s entire second quarter profit.

The Rancho Cordova rocket engine maker reported a $38.1 million quarterly loss Tuesday, largely the result of a spectacular launchpad explosion last October that forced Aerojet to pay a hefty settlement to a key customer and prompted the end of a profitable supply contract. Aerojet, which has embarked on a cost-cutting program, said the third-quarter loss came to 62 cents a share. It compared to a year-ago loss of $9.9 million, or 18 cents a share.

The company’s stock has also been declining, probably linked to its loss of business to Blue Origin.

New global maps of Titan

11:23 am

Titan's North Pole

The Cassini science team has released new maps of Titan, including new maps of both poles, assembled from images taken during the 100 flybys that the spacecraft has made of the moon since it arrived in orbit around Saturn.

The scale is rough, just less than a mile at best, and there is no topographic information because the thick atmosphere allows for no strong sunlight or shadows. The images show differences in surface brightness, which does tell us where Titan’s dark methane lakes are.

This is likely the best we will get of Titan for decades, until another spacecraft is sent there.

Putin delays first launch from Vostochny

9:16 am

During an inspection tour of Russia’s new Vostochny spaceport, Vladimir Putin announced that the first launch should be delayed from December to the spring of 2016.

“We do not need any drumbeating reports, we need high-quality results,” Putin said. “So let us agree: you finish the work related to water supply and wastewater disposal. It is necessary to prepare spaceships for launches. And be ready to carry out the first launches in 2016, somewhere in the spring.” “If you do that before Cosmonautics Day, that will be fine,” the president added.

Cosmonautics Day is the anniversary of Yuri Gagarin’s first spaceflight, April 12, so this is the new deadline Putin is setting. He doesn’t mention anything about the launch assembly building supposedly built to the wrong size.

Cassini’s last flybys of Enceladus

2:04 pm

As Cassini approaches the end of its decade-long mission at Saturn it will begin its last series of flybys of the moon Enceladus starting October 14.

Images will arrive a day or two afterward. The last two flybys will take place in late October and then in December, with the second October flyby getting closest, only 30 miles from the surface.

Beginning next year they will shift the spacecraft’s orbit so that it can get a better look at Saturn’s poles during its last two years. In that orbit flybys of the moons cannot be done.

ULA picks Vulcan launchpads

9:48 pm

The competition heats up: ULA has picked the two launchpads it will use for its new Vulcan rocket.

United Launch Alliance’s next-generation Vulcan rocket will lift off from the company’s existing Atlas 5 launch facilities in Florida and California, according to the company’s Vulcan program manager. The launch pads at Cape Canaveral and Vandenberg Air Force Base will require modifications to accommodate the Vulcan booster, which is wider than the Atlas 5 rocket’s existing first stage, said Mark Peller, ULA’s Vulcan program manager, at the International Symposium for Personal and Commercial Spaceflight in Las Cruces, New Mexico.

This decision mainly outlines how ULA hopes to eventually reduce the number of launchpads it must maintain, and thus reduce its costs.

Next New Shepard test flight expected before December

9:21 am

The competition heats up: Blue Origins has revealed that the next test flight of its suborbital New Shepard capsule and launch rocket will take place before the end of 2015.

They also noted that they will not be selling any tickets for suborbital flights for at least two more years, until they are satisfied that the test flights have proven the system. This is a far cry from other suborbital companies like Virgin Galactic and XCOR, who have made big promises to garner ticket sales, and have yet to deliver. Jeff Bezos’s company has instead decided to deliver first, and then sell tickets.

In the end, we shall see who wins the race to put the first tourists into space. What is certain in all this however is that Virgin Galactic has squandered the ten-year headstart it had when it started out in 2004.

In related news, Virgin Galactic says that construction of its second SpaceShipTwo ship is progressing well.

3D image of Comet 67P/C-G

9:06 am

Do you own red-blue 3-D glasses? Get them out and go to this link. Rosetta scientists have created a 3-D image of Comet 67P/C-G, including the jets of material shooting out from its surface.

[C]reating a 3d anaglyph of dynamic events like this is notoriously difficult: often the jets are too faint or their duration is too short to find two high-quality images taken several minutes apart that are suitable to pair together to create this type of view. However, the OSIRIS team got lucky with this particular event, capturing two images separated by about two-and-a-half minutes.

The image shows a bright, collimated jet embedded in a broader emission structure. The three dimensional perspective also reveals the conical shape of the jet and that the collimated feature is emitted towards the observer.
