Commercial communications satellites for Mars?

The competition heats up? NASA is considering a different commercial approach for providing communications to and from its Mars probes.

The purpose of NASA’s request for information, or RFI, released July 23 “is to explore new business models for how NASA might sustain Mars relay infrastructure, consisting of orbiters capable of providing standardized telecommunication services for rovers and landers on the Martian surface, in the Martian atmosphere, or in Mars orbit,” according to a posting on the Federal Business Opportunities website.

According to the post, NASA will use information it receives from respondents to inform its future Mars exploration strategies, but the agency has not decided to pursue a commercial interplanetary telecom initiative. “We are looking to broaden participation in the exploration of Mars to include new models for government and commercial partnerships,” said John Grunsfeld, associate administrator of NASA’s science mission directorate, in a statement. “Depending on the outcome, the new model could be a vital component in future science missions and the path for humans to Mars.” [emphasis mine]

It is important to highlight the fact that NASA has not yet made a decision on this issue. The best thing the agency could do, in my opinion, would be to step back, design nothing, but let private companies bid on providing the service. The expertise at many of the private satellite companies providing communications efficiently and inexpensively to private customers worldwide would easily provide NASA better communications at Mars for less money.

In other words, like manned flight and cargo delivery to ISS, NASA should simply become a customer, and let private companies build and own the products that NASA buys.

SpaceX scores first in its suit against the Air Force

A federal judge has denied the motion of the Air Force and ULA to dismiss SpaceX’s suit against their block buy launch contract that excludes competition from any other company.

The judge also required the parties go to mediation to settle their differences. Both rulings give added weight to SpaceX’s main complaint, that the company as well as others should have the right to compete for this Air Force launch work.

Sierra Nevada signs deal with Japan

The competition heats up: Japan has signed a development agreement with Sierra Nevada in connection with its Dream Chaser manned spacecraft.

I was also tempted to preface this post with the phrase, “Who needs NASA?” Sierra Nevada has a viable product that can get humans into space cheaply. Several countries, Germany, now Japan, want to get their own citizens into space, and have realized what a bargain Dream Chaser is. Sierra Nevada is taking advantage of this demand to sell its product worldwide. If Congress decides to defund them, or NASA decides not to pick them to continue development, they very clearly intend to build the ship anyway. It just won’t be used to put American astronauts into space.

Falcon 9 soft lands on water

SpaceX claimed in a press release on Tuesday that it had successfully completed a soft splashdown of the first stage of its Falcon 9 rocket in its launch earlier this month.

Video below the fold. The quality is not great because of a buildup of ice on the camera, but it does show they were able to restart the engines twice after separation. It also shows the landing legs deploy just before the stage hovers above the water.

Was Yutu stopped by rough ground?

One of the designers of the Chinese lunar rover Yutu said in a news interview today that the rocky nature of the Moon’s surface, far rougher than expected, was what caused it to stall.

The rover was tested in Beijing, Shanghai and the desert in northwestern China before its launch, but the terrain of the landing site proved to be much more rugged than expected, said Zhang Yuhua, deputy chief designer of the lunar probe system for the Chang’e-3 mission. “It is almost like a gravel field.”

Data from foreign researchers projected that there would be four stones, each above 20 cm, on average every 100 square meters, but the quantity and size of the stones that Yutu has encountered has far exceeded this expectation, Zhang said in an exclusive interview with Xinhua. “Experts’ initial judgement for the abnormality of Yutu was that the rover was ‘wounded’ by colliding with stones while moving,” she said. [emphasis mine]

The implication of the highlighted quote is that it isn’t their fault, it was the fault of those evil Americans and Russians who incorrectly estimated the roughness of the ground. This article also doesn’t fit the information released when Yutu first stalled, where they explained that their problem was partly an inability to retract equipment in preparation for lunar night. While this story could be true, it isn’t the whole story.

Europe readies its own space plane for test flight

The competition heats up: Europe ‘s Intermediate eXperimental Vehicle (IXV) is undergoing its final tests before it does a suborbital test flight in November.

IXV will be launched into a suborbital trajectory on ESA’s small Vega rocket from Europe’s Spaceport in French Guiana, the vehicle will return to Earth as though from a low-orbit mission. For the first time, it will test and qualify European critical reentry technologies in hypersonic flight, descend by parachute and land in the Pacific Ocean to await recovery and analysis. IXV is manoeuvrable and able to make precise landings—it is the ‘intermediate’ element of Europe’s path to future developments with limited risks. …

When IXV splashes down in the Pacific at the end of its mission it will be recovered by ship and returned to Europe for detailed analysis to assess the performance and condition of the internal and external structures. The actual performance will be compared with predictions to improve computer modelling of the materials used and the spaceplane’s design.

Though exciting, Europe will have to pick up the pace from its normally slow pace on these kinds of projects if it expects to be competitive. In the past, they would stretch out the development as long as they could in order to keep the cash flowing. This won’t work in the increasingly robust aerospace market that exists today.

UrthaCast progress

The competition heats up: UrthaCast has announced the status of the commissioning of its commercial cameras on ISS for viewing the Earth.

The medium resolution camera has been commissioned and is available for commercial imaging. The high resolution camera, however, has a problem with its pointing system which is requiring troubleshooting.

The Bi-axial Pointing Platform (“BPP”), which controls the pointing of the [High Resolution camera (HRC)], is experiencing difficulties in achieving the pointing control precision needed for the HRC to meet image quality specifications. Our engineering team together with RSC Energia believes it has developed a solution to this problem using existing gyroscopes on the HRC to improve the BPP pointing control. This solution has been successfully tested on the ground. The on-orbit implementation of this solution requires software updates and the installation of additional cabling inside the Zvezda module. These new cables need to be delivered to the International Space Station (ISS). As a result, there will be a several month delay in commissioning the HRC.

Another ISEE-3 update

The team trying to resurrect ISEE-3 had very mixed results in its attempt today to get the spacecraft’s propulsion system working.

They managed to get “several instances of thrust,” which suggests there is fuel, the system can function, and that their strategy is on the right track. They did not however get full thrust as hoped, and are not quite sure why the spacecraft only partly responded. They are analyzing the data while they apply to NASA for an extension of their license to transmit to the spacecraft.

This last point is merely a formality. What can NASA do if they continue anyway? Nothing. NASA will say yes, partly because it is good public relations and partly because most of the people at NASA are also fans of this effort.

The UAE wants to go to Mars

The competition heats up: The United Arab Emirates (UAE) announced today that it is creating a space agency to build and launch an unmanned mission to Mars by 2021.

The announcement included this statement by his Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai:

Despite all the tensions and the conflicts across the Middle East, we have proved today how positive a contribution the Arab people can make to humanity through great achievements, given the right circumstances and ingredients. Our region is a region of civilisation. Our destiny is, once again, to explore, to create, to build and to civilise. We chose the epic challenge of reaching Mars because epic challenges inspire us and motivate us. The moment we stop taking on such challenges is the moment we stop moving forward.

I wish them luck, since building spaceships and exploring the heavens is a far better occupation that trying to kill Jews. I remain skeptical however. They will have to show real achievement before I will believe this is something more than a simple feel-good public relations stunt by the UAE’s leaders.
