The first preliminary list of candidate landing sites for NASA’s next Mars rover have been proposed.

The first preliminary list of candidate landing sites for NASA’s next Mars rover have been proposed.

At the conclusion of the workshop, attendees voted informally on the nearly 30 candidate sites that researchers had presented—ranking the sites as being of high, medium, or low scientific interest. Floating to the top was a site called Northeast Syrtis Major, a terrain at the edge of the Isidis Basin, the remnant of one of Mars’s biggest and most ancient asteroid impacts. Jack Mustard, a planetary scientist at Brown University and an advocate for the site, says material from the impact could offer a precise date for that event. Scientists also want a piece of nearby lava flows, thought to have oozed out and cooled several hundred million years later.

Nothing is even close to being decided yet, however.

In related news, a new study suggests that dozens of microbes might have stowed away on Curiosity when it left for Mars.

Emphasis must be placed on the word “suggests” however.

The launch failure Thursday of a Russian Proton rocket is putting the squeeze on the commercial satellite industry.

The competition heats up: The launch failure Thursday of a Russian Proton rocket is putting the squeeze on the commercial satellite industry.

Periodically I am told by launch industry experts that the launch industry doesn’t have sufficient demand or capacity for more launch companies. It was this logic, for example, that prompted Boeing and Lockheed Martin to combine into ULA and do a bulk buy with the Air Force. Otherwise, they claimed, they didn’t have enough business to compete with each other and stay in business.

This article above puts the lie to these claims. Not only is there plenty of demand, companies like SpaceX would probably up their fees if they wanted to because the supply does not even come close to meeting the demand. In fact, satellite companies want to get their satellites into orbit and can’t because of a shortage of launch services.

This shortage is an opportunity, not only for the companies that exist but for any new companies trying to get started, such as Stratolaunch. Rather than sit on their hands, as have Boeing and Lockheed Martin, an ambitious and competitive effort here could win market share and make lots of money.

A replacement commencement speaker for someone forced out by student protests today strongly criticized the students in his speech today.

Standing up for freedom: A replacement commencement speaker for someone forced out by student protests today strongly criticized the students in his speech today.

William G. Bowen, former president of Princeton and a nationally respected higher education leader, called the student protestors’ approach both “immature” and “arrogant” and the subsequent withdrawal of Robert J. Birgeneau, former chancellor of the University of California Berkeley, a “defeat” for the Quaker college and its ideals.

I would hope more speakers did this. Sadly, I don’t get the impression many are.

Virgin Galactic pretty much admits that SpaceShipTwo will fly to only fifty miles altitude, not 62 (100 kilometers).

Virgin Galactic pretty much admits that SpaceShipTwo will fly to only fifty miles altitude, not 62 (100 kilometers).

The admission came in response to the rumors that say the spacecraft will even have trouble reach 50 miles.

Though the company is making a hard PR effort to dispel the negative rumors that are swirling about in the press, the only way they will really succeed at this is to begin actual test flights, something that has not happened, as they have promised repeatedly since the first powered flight last year.

The assembly of Boeing’s CST-100 manned spacecraft is expected to begin soon.

The competition heats up: The assembly of Boeing’s CST-100 manned spacecraft is expected to begin soon.

Boeing takes over the OPF-3 lease in late June 2014 following an official handover ceremony from Space Florida. Assembly begins soon thereafter. … “The pieces are coming one by one from all over the country,” Ferguson explained. “Parts from our vendors are already starting to show up for our test article. “Assembly of the test article in Florida starts soon.”

Granted, Boeing’s lease for its assembly space at Kennedy has not yet started, but the vagueness of the assembly start date is a bit curious, and suggests that Boeing won’t begin assembly until they know they have won the contract from NASA, the announcement of which is presently scheduled for late summer 2014.

The Air Force has hired the Aerospace Corporation to evaluate how long it will take to replace the Russian engine used by the Atlas 5 rocket.

Government dithering: The Air Force has hired the Aerospace Corporation to evaluate how long it will take to replace the Russian engine used by the Atlas 5 rocket.

“I see numbers all over the map,” [Ray Johnson, vice president at Aerospace] said May 14 during the World Space Risk Forum here. “Some people say they could do it in five years. Others estimate it’s going to be longer than that, and that it could be eight.” Aerospace Corp. work evaluating what it would take to develop a hydrocarbon engine to replace the RD-180 — if U.S.-Russia relations sour to the point where the engine is no longer available or wanted — “is literally just a few weeks old,” Johnson said.

Time is critical on this issue. It seems to me a better thing to do would be to immediately issue of Request for Proposals, which would quickly tell the Air Force what the American aerospace industry has to offer. They could then proceed right to construction, rather than studying the issue endlessly beforehand.

Moreover, why isn’t Lockheed Martin doing something about this? It is their rocket that is dependent on the Russians. Why is it the Air Force’s responsibility to save them?

NASA has approved a new mission for the crippled Kepler space telescope, allowing observations to continue for another two years.

Like a phoenix: NASA has officially approved the new mission for the crippled Kepler space telescope, allowing observations to continue for another two years.

During the K2 mission, Kepler will stare at target fields in the plane of Earth’s orbit, known as the ecliptic, during observing campaigns that last about 75 days each. In this orientation, solar radiation pressure can help balance the spacecraft, making the most of Kepler’s compromised pointing ability, team members said.

Hopefully the application of clever engineering will allow scientists to get data good enough to spot some more exoplanets.
