The new commercial space companies question NASA contracting policies

3:02 pm

The new commercial space companies are challenging NASA’s new contracting policy.

The article covers the conflict that I described in this post, whereby NASA is abandoning the more flexible contracting approach used for the commercial cargo contracts of SpaceX and Orbital Sciences and going instead with the contracting system it used for all past NASA subcontracts.

The article is errs badly when it calls the new contracting approach that NASA wants to use “non-traditional.” It is instead the way NASA has been doing things for decades, whereby the agency takes full control of everything and requires contractors to fill out so much paperwork that the costs double and triple.

Space Boat: A Nautical Mission to an Alien Sea

10:40 pm

The Titan Mare Explorer: A nautical mission to an alien sea.

If [NASA] green-lights the mission, the capsule will lift off in 2016. By 2023, TiME will be about 800 million miles away in Titan’s north-polar region, home to its biggest lakes and seas. The capsule will take photographs, collect meteorological data, measure depth, and analyze samples. TiME will have no means of propulsion once it is on Titan, so it will float, carried by breezes across the sea’s surface. Then, by the mid-2020s, it will enter a decade-long winter of darkness as the moon’s orbit takes it to the dark side of Saturn, away from the sun and communication. It won’t have a line of sight to Earth to beam back more data until 2035.

American manned space: dependent on the Russians in more ways than you think

American manned space: dependent on the Russians in more ways than you think.

As commentators from around the country gnash their teeth at U.S. dependence upon Russia to move cargo and astronauts to the mostly U.S. built/funded International Space Station (ISS), they’ve missed the bigger boat: With one exception, all the commercial spaceflight offerings currently in the works have Soviet or Russian engines as a key part of the rockets involved.

Lack of U.S. government interest in commercial refueling mission causes problems

9:10 pm

A lack of U.S. government interest in a privately designed satellite refueling technology has caused the company to pull back its plans.

MDA had signed a contract with the communications satellite company Intelsat to refuel some of its orbiting satellites, but needed additional customers to make a go of it. It had hoped the U.S. Defense Department would show interest, but they have not.

This is exactly where the government should be investing its capital, and that it is not tells us a lot about the real lack of sincerity behind the Obama administration’s claims that it wants to encourage private space. I also suspect that the turf war with satellite companies and defense contractors helped discourage Defense Department interest.

Dawn begins science operations in orbit around Vesta

2:46 pm

The Dawn science team today released what they are calling “the first full-frame image” of Vesta. The image is shown below the fold.

The picture was taken from 3,200 miles, and shows a pockmarked irregularly shaped world. While many features that resemble the Moon (the craters, the rays radiating out from those craters), that Vesta itself is not spherical makes it very much unlike the Moon. It is probably going to take scientists several months at least to decipher the data they are getting and come up with some concrete conclusions about this strange dwarf planet.

The Painted Desert of Mars

11:58 pm

Mars Reconnaissance Orbiter released this picture yesterday of what the Orbiter’s scientists have labeled “The crazy floor of Hellas Basin.” Below you can see a cropped image of only one part of the large higher resolution image. The NASA caption says that the wild colors probably “indicate that diverse minerals are present,” meaning that any settlers of the red planet will probably take a close look at this location with the reasonable hope of finding the resources they need to colonize a planet.

To me, these colors also indicate that this place on Mars would probably one of its most popular tourist spots. As I look at the image my eye instinctively wants to trace out the best trail route along the ridges and down into the gullies in order to give hikers the best view of this colorful terrain.

ISS partners discuss how to use the space station as a test bed for missions beyond low Earth orbit.

8:43 pm

Now why didn’t they think of this before? The ISS partners met today to discuss how to use the space station as a test bed for missions beyond low Earth orbit.

As I wrote in Leaving Earth, a space station is nothing more than a prototype interplanetary spaceship. This kind of research is really its main purpose, and I am glad that the governments running ISS are finally beginning to recognize it, even though their engineers have known it for decades. Note too that the press release above also gives a nice overview of some of the ongoing research on ISS that is directly related to learning how to survive in space for long periods.

Junk journalism

12:50 pm

In a piece today at the Huffington Post, science journalist Seth Borenstein declares the wonders of NASA’s next mission: to send astronauts to an asteroid by 2025, as declared by President Obama.

If you believe this is going to happen, then I have a bridge I want to sell you. To do it we need a spaceship in which people can live for at least a year, and a rocket to get that ship into orbit. Not only do we not yet know how to build such a spaceship, we no longer have the capability of putting it into orbit. In case you’re unaware (Borenstein acts like he is), the space shuttle no longer exists. And under this administration and Congress, any replacement we get isn’t going to be able to launch such an interplanetary spaceship anywhere in the near future, especially faced as we are with the present federal debt.

The disgraceful thing about this article, however, is the lack of skepticism shown by Borenstein.

Public test of privately built moon lander delayed by gyro

9:45 pm

A public test of privately built moon lander has been delayed by gyro problem. Key quote:

One customer has already bought a ticket with Moon Express, asking them to deposit a small telescope on the dark side of the Moon. Jain says the company will also offer low cost ways for anyone to use the moon as a kind of time capsule. “If something goes to the moon it stays there forever, people will pay to sends things like photos, or maybe your hair or DNA.”
