SpaceX wins NASA satellite launch contract

6:28 pm

The competition heats up: NASA has awarded SpaceX the contract to launch its Earth science satellite, Surface Water and Ocean Topography (SWOT).

This sentence from the press release is puzzling:

The total cost for NASA to launch SWOT is approximately $112 million, which includes the launch service; spacecraft processing; payload integration; and tracking, data and telemetry support.

Since SpaceX touts a launch price for its Falcon 9 rocket as $62 million, I wonder why this launch will cost NASA almost twice as much. Was there so little competition in the bidding that SpaceX could bid higher and thus get more money? Or is NASA so disinterested in saving money that it left itself open to overpaying for something that everyone else gets for far else?

An update on the Bigelow inflatable module on ISS

9:12 am

NASA has released an update on the privately built inflatable BEAM module that is presently attached to ISS and is under-going two years of testing.

NASA and Bigelow Aerospace are pleased to report that, overall, BEAM is operating as expected and continues to produce valuable data. Structural engineers at NASA JSC confirmed that BEAM deployment loads upon the space station were very small, and continue to analyze the module’s structural data for comparison with ground tests and models. Researchers at NASA’s Langley Research Center in Hampton, Virginia, have found no evidence of large debris impacts in the DIDS data to date—good news for any spacecraft. And radiation researchers at JSC have found that the dosage due to Galactic Cosmic Rays in BEAM is similar to other space station modules, and continue to analyze local “trapped” radiation particles, particularly from the South Atlantic Anomaly, to help determine additional shielding requirements for long-duration exploration missions.

None of this is a surprise. It seems to me that this testing program is a bit overdone, since NASA never did anything like this in orbit for its own modules. What I think is really happening is that the two-year test of Bigelow’s module was required politically within NASA because there were too many people there opposed to using a privately-built module. I also suspect that NASA got further pressure from the contractors, such as Boeing, who had previously owned this business, and did not want the competition from Bigelow. Thus, despite the fact that Bigelow has already launched two test modules of its own and proved the viability of its designs, it was forced by NASA to do an additional test under NASA’s supervision in order to squelch this opposition.

Russia postpones Proton launch again

9:03 am

Originally scheduled for October, International Launch Services (ILS), the Russian company that manages its commercial launches, has once again postponed the next Proton rocket launch.

“The new launch date is December 2016,” the website says. The reasons for the postponement have not yet been announced.

As reported earlier, Russia’s space corporation Roscosmos had rescheduled the launch from October 10 to November 23. It was initially scheduled for late June, then postponed to August 29 and then to October 10.

More significantly, there have been no Proton launches since a June 9 launch were the second stage of the rocket inexplicably shut down prematurely. The Russians have been conducting an investigation, but have released absolutely no information about what they have found

Atlas 5 launches NOAA weather satellite

10:53 pm

Successfully completing its second launch in 8 days, ULA’s Atlas 5 rocket put a new NOAA weather satellite in orbit on Saturday.

NOAA is giving this new satellite a big PR push, claiming it will revolutionize weather monitoring and forecasting. While the satellite might be state of the art, it is also was very expensive, costing $1 billion. I strongly suspect that the same thing could have been built far cheaper, and quicker, if left to the private sector.

UAE sheikh okays next phase in Mars mission

10:48 pm

The competition heats up: The Vice President and Prime Minister of the United Arab Emirates and the ruler of Dubai, Sheikh Mohammed bin Rashid Al Maktoum, has approved the start of construction of the prototypes for the UAE’s Mars Mission, dubbed Hope.

Sheikh Mohammed gave the greenlight to start manufacturing the probe’s prototypes, the Arab world’s first Mars probe. The project places the UAE with the nine countries that aim to explore Mars. His Highness said: “UAE ambitions is to explore the outer space. We are investing in our national cadres to lead this project and contribute in expanding our knowledge about Mars. Hope Probe is a qualitative leap for UAE’s scientific efforts, it the first contribution for the Arab world in this regard”.

Sheikh Mohammed’s remarks came while visiting the Mohammed Bin Rashid Space Centre (MBRSC) to open the second phase of the UAE satellite manufacturing and assembly complex, a multitasking facility capable of handling several space projects at a time.

It will be very interesting to see how this top-down mission proceeds, as it is being pushed heavily by the sheikh in a country with almost no experience in building such things.

Ceres’ cratered surface

10:27 am

Ceres' crated surface

Cool image time! The picture on the right, reduced to show here, was taken on October 17 and was the tenth image taken by Dawn in its new extended mission in orbit around Ceres.

This image of the limb of dwarf planet Ceres shows a section of the northern hemisphere. A shadowy portion of Occator Crater can be seen at the lower right — its bright “spot” areas are outside of the frame of view. Part of Kaikara Crater (45 miles, 72 kilometers in diameter) is visible at top left.

The image was taken from 920 miles away and has a resolution of about 460 feet per pixel.

Boeing files FCC application for 3,000 satellite constellation

10:10 am

The competition heats up: Boeing this week submitted its second application to the FCC for its own 3,000 satellite constellation to provide “a wide range of advanced communications and Internet-based services.”

The second application this week specifically requested permission to launch the first 60 satellites. The whole plan is comparable to the one that SpaceX submitted earlier this week, and puts these two companies in direct competition. If both plans are launched, it will mean that more than 6,000 satellites will need launch services to gain orbit, which also means the launch business could get very busy in the coming years.

Boeing and Russia to partner on building lunar space station?

5:22 pm

As part of a settlement with Boeing in the Sea Launch lawsuit, the Russians are proposing a partnership with the American company for building a lunar orbiting space station.

A preliminary dispute settlement deal was reached in August. “We are preparing a document which, apart from finalizing the court case, also creates a program for long-term cooperation on a wide range of issues. We are working on projects to cooperate in low earth orbit, create moon infrastructure and explore deep space,” Solntsev told the Russian Izvestia newspaper. The two companies now plan to create nodes and units capable of synchronizing space technologies, including a docking station for a proposed lunar orbiting station. Meanwhile, Sea Launch settlement documents are set to be signed before the end of November, according to Solntsev.

It will be very interesting to see the actual agreement. I also wonder how much Boeing can really do with Russia without U.S. government approval.

Explosion at SpaceX test site part of launchpad investigation

9:14 am

An explosion yesterday at SpaceX’s Texas test facility appears to have been planned and is part of the company’s investigation into the September 1 Falcon 9 launchpad explosion.

“The sound heard by residents was actually the result of a pressurization test at the McGregor Rocket R&D facility. These tests take place periodically at the site, and this particular test was part of the ongoing testing being conducted by our Accident Investigation Team,” SpaceX spokesman Phil Larson said in an email response to questions. “The volunteer fire department responded as a matter of procedure, but there was no damage to the site or injuries to any personnel.”

I would guess that they are trying to see if they can precisely duplicate the conditions that produced the September 1st explosion, including triggering new explosions in a reliable manner. If so, they would then know precisely what to avoid doing to trigger future tank failures.

Meanwhile, this story notes the successful first pressure tests of the carbon fiber tank that SpaceX is developing for its interplanetary spaceship. Not much information, though SpaceX has released some cool images of the tank being prepped for the test.

SpaceX files FCC application for 4000+ internet satellite constellation

11:56 pm

The competition heats up: SpaceX today filed an FCC application for the construction and launch of a 4,425-satellite constellation designed to provide internet access worldwide.

In the technical information that accompanied its application, SpaceX said it would start commercial broadband service with 800 satellites. That service would cover areas of the globe from 15 degrees north to 60 degrees north, and from 15 degrees south to 60 degrees south. That leaves out some portions of Alaska, which would require a temporary waiver from the FCC.

Eventually, the network would grow to 4,425 satellites, transmitting in the Ku and Ka frequency bands. “Once fully deployed, the SpaceX system will pass over virtually all parts of the Earth’s surface and therefore, in principle, have the ability to provide ubiquitous global service,” SpaceX said.

When Musk first proposed this last year, he said it would take about $10 billion and five years to get it built. So, don’t expect these satellites to fly tomorrow. A lot of other things must happen first before this new plan takes flight.

Software issues threaten Orion/SLS schedule

8:36 am

Despite having more than a decade to develop the software for SLS and Orion, NASA now faces the possibility that the rocket’s first test flight in 2018 might be delayed because that software is not ready.

Specifically, a NASA advisory board has revealed that Orion’s flight software is behind schedule and might not be ready in time. This, combined with schedule problems for the capsule’s service module, being built by the European Space Agency, threatens the 2018 launch date.

Luxembourg establishes its own legal framework for asteroid mining

9:26 am

The competition heats up: Luxembourg on November 11 announced that it is establishing its own legal framework to protect the profits of any private asteroid mining effort.

Because the UN Outer Space Treaty forbids them from claiming any territory in space, this new law essentially says that Luxembourg law will instead be applied specifically to the resources mined. Or to put it in more colloquial terms, “Finders, Keepers,” though it comes with a lot of complex further regulation required to satisfy that treaty.

The draft law also lays down the regulations for the authorization and the supervision of space resources utilization missions, including both the exploration and use of such resources. Whoever intends to undertake a space resources utilization mission will be required to obtain an authorization to do so, for each specific and determined mission. The text sets forth the necessity for a book of obligations for any mission, such as activities to be carried in or out of Luxembourg, to allow government supervision of the activities of operators and regulating their rights and obligations. The legislation is expected to enter into effect in early 2017.

This complexity will cost money unnecessarily, and also require an unnecessary bureaucracy with a great deal of power over the actions of space companies. It illustrates again how really bad the Outer Space Treaty is, and how it will oppress future spacefarers. The sooner the treaty is dumped the better. If we don’t do it here on Earth, I guarantee that the people of space will do it, as soon as they become self-sufficient enough to thumb their noses at the ground-pounders on the mother planet.

Chinese astronauts to return to Earth this week

9:09 am

The competition heats up: After spending a month in orbit in their country’s second orbiting space station module, two Chinese astronauts are expected to return to Earth this week.

The article provides a lot of details about China’s upcoming space station plans. For example, this will likely be the last manned mission to the Tiangong-2 module. It will be used next year to test the docking of an unmanned freighter, but the next manned mission will be to the core unit of their full-sized space station, now set to launch in 2018 on a Long March 5 rocket, which successfully completed its first test launch two weeks ago.

Mars rover update: November 14, 2016

12:10 pm

Curiosity

Curiosity looking south, Sol 1516

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

Since my last update on November 3rd, Curiosity has reached the region of sand dunes and has started to pick its way through it. The panorama above was created using images from the rover’s left navigation camera, taken on Sol 1516. It looks south, with Mount Sharp rising on the left.

That same day Curiosity also used its mast camera to zoom in on the canyon gap in the center of the panorama. The first image below is the wider mast camera shot, with the an outline showing the even closer zoom-in below that.

Oxo Crater on Ceres

10:13 am

Oxo Crater on Ceres

Cool image time! The Dawn image at the right, cropped to show here, was taken on April 19, 2016. It shows the crater Oxo on Ceres and is especially intriguing because it not provides high resolution imagery of the crater’s bright rim, the second brightest feature on Ceres, it also shows how the southeastern part of the crater’s rim has literally slide down into the crater, leaving behind a gaping rombus-shaped pit.

The slumping, combined with the bright material on the rim, is more evidence that at some point in the past Ceres was geologically active.

NASA considers alternatives to Orion

6:33 pm

The competition heats up: Faced with long delays and an ungodly budget, NASA is now considering alternatives to replace the Orion capsule.

NASA has initiated a process that raises questions about the future of its Orion spacecraft. So far, this procedural effort has flown largely under the radar, because it came in the form of a subtle Request for Information (RFI) that nominally seeks to extend NASA’s contract to acquire future Orion vehicles after Exploration Mission-2, which likely will fly sometime between 2021 and 2023.

Nevertheless, three sources familiar with the RFI, who agreed to speak on the condition of anonymity, told Ars there is more to the request than a simple extension for Orion’s primary contractor, Lockheed Martin. Perhaps most radically, the RFI may even open the way for a competitor, such as Boeing or SpaceX, to substitute its own upgraded capsule for Orion in the mid-2020s.

The article also has this juicy quote:

The new RFI states that Lockheed will continue with development of Orion through a second uncrewed flight set for late 2018 and Exploration Mission-2, the first crewed mission, as early as 2021. However, once this “base vehicle” configuration is established, the RFI signals NASA’s intent to find a less expensive path forward. “This RFI serves as an examination of the market, which is an initial step in pursuing any of the available acquisition strategies, including the exercising of existing options,” the document states.

The end of SLS and Orion is beginning.

Russians to put first centrifuge on ISS

9:33 am

Russia today announced that they are developing and plan to launch the first small centrifuge ever to fly in space.

The centrifuge would be installed on an inflatable module that Russia’s Institute of Biomedical Problems, which specializes in studying the medical problems of space travel, is building, and would be used to study the effects of artificial gravity in weightlessness.

Unfortunately, the announcement doesn’t tell us much more than this. Based on previous such announcements from Russia, I would not be surprised if this project never flies.

Using the X-37B as a space ambulance?

10:16 am

Researchers have proposed using the Air Force’s X-37B as an ambulance in space.

Halberg said that an effective astronaut taxi should, among other things, be able to stay at the ISS for two years or more at a stretch; be capable of getting people back to Earth rapidly, within three hours or so; impose minimal G-loads on occupants; have the ability to land close to a hospital; and allow patients to lie in a supine position. These requirements all point to a space plane rather than a capsule, Halberg said — meaning SpaceX’s Dragon capsule and Boeing’s CST-100 capsule, which are scheduled to start flying NASA astronauts to and from the ISS within the next year or two, wouldn’t make the grade as ambulances.

Another private crew-carrying vehicle that’s currently in development, Sierra Nevada Corp.’s Dream Chaser space plane, is an intriguing option that bears further investigation, Robinson and Halberg said. But their initial concept study focused on the robotic X-37B, chiefly because the 29-foot-long (8.8 meters) military space plane has already racked up millions of miles in orbit, while Dream Chaser has yet to launch.

Makes sense, though once Dream Chaser is flying it will have the potential to provide the same service with far greater capabilities.

Orion faces more delays

10:00 pm

Faced with looming schedule problems for Europe’s effort to build the service module for the Orion capsule, NASA has created a working group to attack the problem.

The European Service Module (ESM) element of Orion has been classed as a major schedule driver for the program for some time. The Service Module for Orion was originally going to be an all-American system, under the control of Lockheed Martin. However, a deal back in 2012 resulted in an alliance with the European Space Agency (ESA) to utilize hardware associated with its Automated Transfer Vehicle (ATV).

The deal made sense. NASA’s goal of international collaboration is deemed to be an essential formula for spreading the costs and increasing the viability of NASA’s exploration goals, building on the success of the partnerships that built the International Space Station. Also, the ATV is proven technology, having already proved its worth via a string of successful resupply missions to the orbital outpost.

However, the challenge of combining the technology into what is essentially an American vehicle has resulted in schedule pressures.

Let me once again point out that Orion was first proposed by President George Bush in 2004. Its first official flight, with service module, is now scheduled for 2018. That means it took NASA 14 years to build and launch a unmanned single complete capsule, assuming they can get the service module built in time. That it took that long to build this is shameful. That there is even the slightest possibility that 14 years won’t be enough time to build the service module is downright disgusting, and is another illustration of the complete failure of the federal government.

Note that the previous unmanned Orion test flight in 2014 really doesn’t count. That capsule was a engineering test capsule, designed to test the capsule’s heat shield, even though NASA had already decided before the flight to abandon that heat shield design. In other words, it was a complete waste of money.

Musk predicts mid-December return to flight

5:36 pm

In a cable news interview today, Elon Musk reiterated recent reports that SpaceX expects to resume launches by the middle of December.

That the head of Inmarsat, one of SpaceX’s satellite customers, has confirmed this plan and appears to have no problem with it, suggests to me that SpaceX is on solid ground and that they have pinpointed a solution to the launchpad explosion that will not require any major re-engineering.

Vector teams up with private company for low-cost launch tracking capability

9:50 am

The competition heats up: The new smallsat rocket company Vector Space Systems has signed a deal with Atlas Space Operations, a private company focused on providing low-cost launch and satellite tracking capabilities.

As early as 2018, Vector Space Systems will be able to provide a space-to-ground communication network from the Galactic Sky division to its customers through ATLAS LINKS™ – the world’s first mobile, rapidly deployable, and electronically steered array RF ground system that is revolutionizing the space industry. Designed for communications with both low-earth orbit and deep space missions, and capable of rapid deployment anywhere on the globe – ATLAS LINKS™ arrays will enable Vector Space Systems to simultaneously track signals over multiple frequencies, effectively eliminating high civil engineering costs associated with the installation of other systems that require expensive antennae and pedestals. Satellite ground architecture and data services will support Vector Space Systems’ launch operations from the ground and in-orbit, transforming satellite telemetry tracking and command systems (TT&C) and ground operations for space startups.

In other words, Atlas is in direct competition with the antenna network of NASA’s Deep Space Network, and is designed to be cheaper and more flexible.

Luxembourg invests $28 million into asteroid mining company

9:43 am

The competition heats up: In its continuing effort to make money from space, the government of Luxembourg has invested $28 million in the asteroid mining company Planetary Resources.

As part of the deal, Planetary Resources is establishing a European headquarters in Luxembourg that will conduct research and development activities. Georges Schmit, a member of the Space Resources advisory board to the Government of Luxembourg, wil join Planetary’s board. “We plan to launch the first commercial asteroid prospecting mission by 2020 and look forward to collaborating with our European partner in this pivotal new industry,” said Chris Lewicki, Planetary Resources chief executive.

As with Luxembourg’s other deals, the investment has required the company to shift many of its operations from the U.S. to Luxembourg.
