Paul Spudis on NASA and the VSE
Paul Spudis gave his views, positive and negative, on NASA's implementation of President Bush's Vision for Space Exploration at the ISDC 2007. Here is a simplification:
Pros:
Pros:
- RL-10 engine can use in-situ lunar propellant
- Building an Outpost on the lunar south pole
Cons:
- Lack of Robot Probes
- Lunar orbit rendezvous instead of an Earth-Moon L1
- Ares
But the biggest complaint was that NASA's lack of a single complete mission.
Glenn Reynolds on the ISDC Conference
Glenn Reynolds has a post on the ISDC 2007 and the blogging panel (which I was invited to, but couldn't make sadly.) He was encouraged by all the investors that showed up. So am I.
China's Military Space Program
China has been very vocal about its growing space launch capabilities and manned space milestones. However, they have been silent about their military counterspace capabilities. Some members of the pentagon say China has a "robust, multidimensional counterspace program." After January's ASAT test, one has to assume China is developing more technology to at least limit other countries access to space.

NASA is Looking for Private Partners
NASA is looking for private company's to develop technology necessary for living on the Moon. Neil Woodward, acting director of NASA's Exploration Systems Mission Directorate, speaking at the ISDC in Dallas.
He did make this earth-shattering statement:
Gosh, you think?
He did make this earth-shattering statement:
If we could be in a commercial relationship with somebody who has the capability that's fine because in many cases they can do it for less money than we can," he told Reuters on the sidelines of a space development conference in Dallas.

Benson to do Redesign of Dream Chaser
As a result of a five month-long study by SpaceDev, Benson Space Company (BSC) has chosen to pursue a fresh approach in the design of its Dream Chaser spaceship, it was announced today by BSC Chairman and President Jim Benson.
Rather than using the orbital NASA HL-20 vehicle as a model, BSC will base its suborbital spaceship on an amalgam of the NASA and Air Force X-2, X-15 and T-38 vehicles. While the new design is safer and more aerodynamic, explains Benson, it will also be easier and faster to construct, allowing BSC to remain on-schedule to make its initial commercial spaceflights in 2009 -- aiming to provide the first, safest and best astronaut-making spaceflights for the emerging space tourism market.
"The mandate of our initial five-month Phase I study, which began in November, was a design review to ensure that we had the very best spaceship possible. During the past two months a small, highly experienced team has taken a fresh look and concluded that we can do better," says Benson. "To that end, the new spaceship will incorporate the best elements selected from other successful vehicles. This will result in a spaceship that provides a better ride and even more spectacular views, and at this early stage we will lose little time in bringing it to the commercial market."
The new Dream Chaser spaceship design is lighter and sleeker, resulting in less drag and requiring less propulsion than the earlier design. The vehicle, powered by safe hybrid rocket motors, will launch vertically and glide to a landing at the launch site. A safer carefree reentry, after achieving an altitude of at least 65 miles, will subject passengers to minimal G-forces, compared to other designs. It will also have many large, well-placed windows for ideal passenger views of the Earth and space.
About Benson Space Company
Established in September 2006, Benson Space Company (BSC) seeks to provide the first, safest and lowest cost astronaut-making spaceflights for the emerging personal spaceflight market. BSC is led by Jim Benson, founder of Compusearch and founder and former chairman and CEO of SpaceDev, which developed the world's only hybrid rocket motors used for human spaceflight. Under Benson's guidance for nearly a decade, SpaceDev designed and produced an innovative satellite for NASA and the hybrid rocket motor technology for Paul Allen's SpaceShipOne, the vehicle that won the $10 million Ansari X Prize in 2004. BSC is currently developing Dream Chaser spaceships, based on proven designs, which will allow BSC to offer the world's first, commercial, suborbital spaceflights.

US Military creates Operationally Responsive Space Office in New Mexico
The United States military has opened a new office for Operationally Responsive Space at Kirtland Air Force Base in New Mexico. Col Kevin McLaughlin is the director.
The mission of the new office is to develop, test and more rapidly deploy satellites if existing, bigger satellites were attacked or damaged in natural disasters. “There’s a realisation that some of these (satellite) assets are vulnerable,” said Col Kevin McLaughlin. The ORS Office here will be focused on smaller satellites, smaller boosters and getting those capabilities into the hands of the warfighter.
Here is the release from Kirtland Air Force Base.

China is Creating an Asian Space Club
China is using it new found space chops to create a sort of "space club" in Asia and Africa. I just finished launching a Nigerian satellite (which it built and financed). Now it is partnered with Bangladesh, Indonesia, Iran, Mongolia, Pakistan, Peru and Thailand to develop an earth observation satellite system. An Asian space association is now in the works.
One has to wonder if China is trying to use it space power as an influence to create a kind of NATO in Southeast Asia and Africa. By bringing countries, rich in natural resources, into the information age with satellites, China is becoming leaders in that area of the world much like the US and parts of Europe are leaders in the west.
Only time will tell what this means for the rest of the world.

Mars Dirt Points to Water
While exploring the great red planet, Spirit, that spunky little rover, knocked over some dirt that relaved a lot of (90%) silica. This is strong evidence added to that already found that Mars was once a wet planet.
Spirit and Oportunity are 3 years over their orginal 3 month mission. One or poor Spirit's wheels has stopped rolling. That is what caused this discovery, the dragging of one wheel across the ground.

"If you made a list of things that are most worthwhile, space would be nowhere near the top of the list," Nally said."But if that sounds like space missions are wasteful or non-urgent, there are a hell of a lot more wasteful and non-urgent things that we already do on Earth that we could can first."

Dark Matter?
NASA, led by Myung-kook James Jee, has found evidence of a ring of dark matter.
dark matter refers to hypothetical matter of unknown composition that does not emit or reflect enough electromagnetic radiation to be observed directly, but whose presence can be inferred from gravitational effects on visible matter. According to present observations of structures larger than galaxy-sized as well as Big Bang cosmology, dark matter accounts for the vast majority of mass in the observable universe.

Genesis II Launch Moved to Late June
This just from Bigelow Aerospace:
Las Vegas, NV 05/17/07 – Bigelow Aerospace has been informed by its launch provider ISC Kosmotras (“Kosmotras”) that additional testing of the Dnepr rocket and its ground equipment is being required by Russian authorities.
Due to last year’s Dnepr failure, these new and additional tests have been requested to identify any remaining issues with the system and enhance the overall chances of achieving our primary objective of mission success. Unfortunately, these procedures will create an additional four week delay. We now expect the launch of Genesis II to occur in late June.
Again, no one likes launch delays and we wish the situation were otherwise. However, we experienced similar delays on the Genesis I campaign and, of course, were quite pleased with the end result. Moreover, since Genesis II contains a variety of important mementos, photos, and other personal items as part of our pilot “Fly Your Stuff” program, both Kosmotras and Bigelow Aerospace are proceeding with great caution in order to safely and successfully deliver the spacecraft to orbit.
The path to space has never been and will never be simple or easy. However, whether it’s Genesis II or the ongoing work with our future spacecraft Galaxy and Sundancer, we at Bigelow Aerospace are dedicating ourselves to building the foundation for a brighter future, and we hope that all of you will continue to share in the adventure.

Interoperability in Space
I was down to my last 30 minutes of air. Why did I come out on this damn solo hike? I was 25 km from Goddard Colony but because of the damn crater ridge, my radio signal can’t get through. Admittedly, this entire hike wasn’t planned well. I have been sitting on this damn spot for almost an hour trying to get somebody on comms.
To bad we only have two satellites in orbit. Of course neither one is in range for another two hours. We don’t have the launch capability yet, and Earth doesn’t think a small localized colony needs satellites for intra-moon communications, they bastards.
Oh crap, my leg just went numb. That can’t be good. Maybe if I twist around this, wait! Is that a rover? I think it is one of the Chinese rovers. Thank God! Come on guys, pick up the phone. Wait, they turning around. Damn, they can’t hear me, there’s no air. Why don’t they pick up?
The Lord is my Shepard, I shall not want…
---------------------------------------------
“In today’s top story, A young man was found dead 25 km from Goddard Colony at the foot of the largest crater. Apparently he had broken his leg and the crater broke “line-of-site” communications with the colony. According to officials he ran out of air this morning about 11:00 am GMT.
According to rescue workers, a Chinese mining crew passed near his position but due to non-standard comms formats, were unable to hear the distress call.
This latest tragedy has cause heated debate on both lunar communications satellites and standard radio formats across all lunar areas.
This is Debra Jones reporting.”
---------------------------------------------
Interoperability on Earth is a problem. I know, it is why I have a job. The military needs divisions to be able to communicate at all times. Problem is, they don’t tend to think of it until after it’s needed (like during a war). Then it costs a fortune to retrofit and design comms equipment to translate for each group.
I believe the problem will be worse on the Moon if we don’t plan ahead. At least on the Earth we have air so we can shout at each other over short distances. The Moon has no such luxury. If you can’t talk over radio (or laser or whatever) you can’t talk.
The history of deep space communications is a tail of mission specific message formats:
Most NASA spacecraft use X, Ka, Ku, or S-band radio and Reed-Solomon convolution encoding. The problem is, as I have seen in the past, they are developing the communications for the mission.
That may sound stupid, but think about it. If each mission has its own message format (even if it does use the same frequency and encoding) nobody can talk to each other.
You have to design an expandable message format the most everyone (tactically important comms aside) can use. We need to design a space TCP/IP that we can all develop spacecraft to fit. Not for a mission with a specific infrastructure, but with an expandable non-defined infrastructure.
There have been positive steps. The CCSDS has worked to create international communications standards. In fact, over 300 space missions have launched with CCSDS comm standards.
If new space is going to take off, we really need a way for a stranded SS3 to call a Bigelow station for help. Safety, reliability, trade, and development cost all beg for it.
