Lunar landers/rovers for sale!

10:40 pm

Moon Express, one of the five finalists trying to win the Google Lunar X-Prize (GLXP) before it expires at the end of this year, announced today its long range plans, focused on building low cost lunar landers rovers, and sample return missions that could be purchased and launched for a tenth the cost of a typical government mission.

The GLXP mission won’t be the last lunar voyage for Moon Express, if all goes according to plan. Its deal with Rocket Lab covers up to five launches, and Moon Express wants at least two more to occur in the next few years, Richards revealed during a news conference today.

The first post-GLXP mission, scheduled to launch in 2019, will set up a robotic research outpost near the lunar south pole and prospect for water and other resources. Then, in 2020, Moon Express will launch the first commercial lunar sample-return mission. That effort, Richards said, should prove out the company’s technologies and its business model, which is centered around creating low-cost access to the moon’s surface for a variety of customers. The core piece of hardware to make all of that happen is a single-engine lander called the MX-1, which will launch on the GLXP flight. Moon Express aims to mass-produce the MX-1, sell it as a stand-alone lunar explorer and have it serve as a building block for three larger, more capable spacecraft — the MX-2, the MX-5 and the MX-9, Richards said today.

The MX-2 combines two MX-1s into a single package, boosting the MX-1’s payload capacity in Earth-moon space and potentially enabling missions to Venus or the moons of Mars. As their names suggest, the MX-5 and MX-9 incorporate five engines and nine engines, respectively, and broaden the exploration envelope even further, Richards said. All of these spacecraft will be available in orbiter, lander and deep-space variations, and the MX-5 and MX-9 vehicles will also come in a sample-return configuration.

Moon Express has not revealed how much it will charge for any of these spacecraft. However, company representatives have said that, together, the MX-1 and Electron can deliver a lunar mission for less than $10 million (that’s “cost,” not retail). Electron flights currently sell for about $5.5 million apiece, putting the lander’s raw cost at $4.5 million or less.

Essentially, they are taking the revolution in satellite technology that is making everything smaller and cheaper and applying it to planetary exploration. They are then offering this technology as a very cheap and fast option for scientists and governments. Based on these numbers, a mission to the Moon could cost a customer less than $20 million, which is nothing compared to a typical NASA mission. Even India’s Mars Orbiter was several times more expensive than this.

While I consider NASA’s planetary program second to none, and one of the best things it does, Moon Express is demonstrating, as has SpaceX with launch services, that private enterprise, if given the chance, can do it better.

Juno images of Great Red Spot released

5:42 pm

The Juno science team has released the images taken by Juno as it flew past Jupiter’s Great Red Spot on June 11.

The three images at the link were all processed by citizen scientists, who took the raw images provided immediately and enhanced the colors. Not surprisingly, the images reveal that there are storms within storms within storms inside the Spot, which itself is a storm, the largest in the solar system.

Mars rover update: July 12, 2017

2:49 pm

Summary: Curiosity looks at some big dune ripples, then creeps up hill. Opportunity tests its wheels.

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

The interior of a dune ripple

Since my last update on June 23,, Curiosity has worked its way around and, for a few days, even into the small sandy field at the base of Vera Rubin ridge. The scientists noticed that the sandy here had a series of large ripples, and they wanted to take a close look at at least one. The image on the right, cropped to show here, was taken shortly after they had the rover drive through one ripple in order to expose its interior. You can see the robot arm directly above the cut created by the rover’s wheels. On the cut’s wall several distinctly different toned layers are visible. A close look reveals that they are wavy, and probably indicate numerous and repeated overlays as the wind brushes a new layer of dust on top of old layers, time after time. The different tones indicate a change in the material’s composition, which could reveal something about some past events in either Mars’ weather or geology.

In order to decipher this information, however, they will need to be able to date the layers, and figure out when each tonal change happened. I am not sure Curiosity can do this, especially since they have not scooped up any of this dust for later analysis.

They are now approaching Vera Rubin Ridge, and should climb up onto in the coming weeks. At that point they will move off the Murray Formation, where they have been since March 2016, made up of dried and ancient crushed mud, and up onto a lighter, yellowish layer of rock, dubbed the Hematite Unit. This October 3, 2016 press release. gives a good outline of the geology of these regions.

Evergreen College already admits to drop in enrollment

10:29 am

While trying to poo-poo the significance, the president of Evergreen College, who allowed mobs to take over his university campus and even hold him hostage because someone might disagree with them, has admitted that he has already seen a “slight decline” in enrollment.

Meanwhile, he has refused to punish any of the students or facility who were part of the mob, even though there are amply videos of them, including some where they actually identify themselves.

I expect this “slight decline” to turn into a flood come next year.

Africa and space

10:07 am

Link here. Prompted by the launch last week of Ghana’s first satellite from ISS, this article take a look at what other African countries are doing to become players in the new colonial movement, noting efforts being done by Nigeria, South Africa, Ethopia, Angola, and Kenya.

Overall, no African country is doing very much in space. The fact that this African-centered news outlet feels compelled to note this, however, suggests that the competitive urge might be stirring there.

Space law vs the Outer Space Treaty

9:42 am

My new op-ed at The Federalist is now online. Other than changing the title from my proposed version above to something a bit more unwieldy, “What You Need To Know About The Space Law Congress Is Considering,” they have posted it exactly as I wrote it.

The essay provides a very detailed analysis of the commercial space law that the House is presently considering. While they are proposing many good reforms, my conclusion unfortunately sums things up:

W.E.B. Du Bois, in studying the African slave trade, once asked, “How far in a State can a recognized moral wrong safely be compromised?” and answered his own question by saying that it is dangerous for “any nation, through carelessness and moral cowardice, [to allow] any social evil to grow. . . . From this we may conclude that it behooves nations as well as men to do things at the very moment when they ought to be done.”

The Outer Space Treaty poses limits on property rights. It also does not provide any mechanism for peacefully establishing sovereignty for any nation on any territory in space. Yet national sovereignty and territorial control is a given in all human societies. If we do nothing to establish a peaceful method for creating sovereignty and national territories in space, nations are going to find their own way to do it, often by force and violence. It behooves us to have the courage to face this issue now, and “do things at the very moment when they ought to be done.”

Read it all.

John Williams – Raider’s March

6:01 pm

An evening pause: From one of the best films ever made, Raiders of the Lost Ark (1981). As I wrote about it at the time for a comic book fan group, it recognizes that there is good and evil, and that there is something in the universe that casts judgement on each. Such concepts had and continue to be largely rejected by modern intellectualism, at our peril.

Hat tip Edward Thelen.

Hamas has made Gaza unliveable, according to the UN

11:17 am

A UN study has found that in the ten years since Hamas took control of Gaza the place has become unliveable for its residents.

A decade after the Islamist group Hamas seized Gaza, the Palestinian enclave is effectively unliveable for its 2 million people, with declining incomes, healthcare, education, electricity and fresh water, the United Nations said.

In a report examining humanitarian conditions in the territory, which Hamas took over in June 2007 after a brief conflict with forces loyal to the Palestinian Authority, the United Nations concludes the situation in Gaza is deteriorating “further and faster” than was forecast only a few years ago. “Across the board we’re watching de-development in slow motion,” Robert Piper, the UN Coordinator for Humanitarian Aid and Development Activities in the Occupied Palestinian Territory, told Reuters in an interview on Tuesday. “Every indicator, from energy to water to healthcare to employment to poverty to food insecurity, every indicator is declining. Gazans have been going through this slow motion de-development now for a decade.”

The article tries to lay the blame on everyone, including Israel, while somehow ignoring the corruption and terrorist roots of Hamas itself. Still, the real blame might belong to the people in Gaza themselves. After Israel unilaterally pulled out in an effort to exchange “land for peace,” the people of Gaza voted for their own leadership, and choose Hamas, a terrorist organization whose reason for existing is to kill Jews and destroy Israel. After making a poor decision like that, no one should be surprised it their circumstances immediately began to decline. We all get the government we deserve.
