Vector Space Systems plans launches from Kennedy

6:52 pm

The competition heats up: Vector Space Systems will this weekend erect a test version of its two-stage Vector-R rocket and launch platform for display at the Kennedy Space Center Visitor Center.

CEO Jim Cantrell also “will announce the intention of the company to use the launch facilities in the future,” according to Space Florida. The two-stage Vector-R — the “R” is short for Rapid — stands 42 feet tall and measures 42 inches around, and is designed to deliver micro-satellites weighing up to about 135 pounds to orbit. The rocket is expected to debut in 2018, flying up to six times. The company eventually envisions launching 100 or more times a year.

Much of this sounds like a bit of PR aimed at the public, not an actual flight plan. However, if they are prepping for an eventual launch at Kennedy there is also no reason they shouldn’t hype that fact beforehand.

More strike actions delay Ariane 5 again

6:47 pm

Protests by local workers that have blocked roads has forced Arianespace to once again delay the Ariane 5 launch of two commercial satellites.

Local newspaper France Guyane reports that local electricians, hospital employees, farmers and transportation workers — including the drivers that transport the Ariane 5 rockets — are among those protesting working and living conditions in the South American town that’s home to Europe’s main launch center. Locals blocked roads around Kourou Monday and Tuesday, preventing Arianespace from transferring the rocket from the final assembly building at the spaceport to the launch zone. Evry, France-based Arianespace launches the Ariane 5, Soyuz and Vega rockets from the Guiana Space Center.

…Local employees of Endel, the French industrial maintenance company that trucks the Ariane 5 rockets for Arianespace, are striking to reopen wage negotiations. Those discussions began Monday night, but failed to reach an agreement, according to France Guyane. The paper reports that other members of the union UTG, as well as the French Democratic Confederation of Labor (CDTG) and Force Ouvrière unions, are also involved in various demonstrations.

The Guyanese Union of Road Transport (UGTR) is also protesting the use of foreign trucks from the European construction company Eiffage, France Guyane says. CNES in July awarded Eclair6, a consortium led by Eiffage, a $222.2 million contract 2016 to build the launch facility for the future Ariane 6 rocket. UGTR said it asked the spaceport not to bring in foreign trucks to do work that that its members could do with equally capable trucks of their own.

None of this is going to help Arianespace in its effort to compete in the modern very aggressive launch industry.

Rocket Lab raises $75 million

6:43 pm

The competition heats up: Rocket Lab announced today that it has raised an additional $75 million in investment capital.

The new funding round is led by venture capital firm Data Collective, with contributions from another VC firm, Promus Ventures, and an undisclosed investor. Several prior investors, including Bessemer Venture Partners, Khosla Ventures and K1W1, also participated in the round.

Rocket Lab said the Series D round brings the total raised by the company to $148 million, and values the company at more than $1 billion. Rocket Lab announced a Series B round of unspecified size in 2015, and Peter Beck, the company’s chief executive, said the company did an unannounced Series C round in the interim involving only existing investors.

In an interview, Beck said the money will go towards increasing the production capacity for its Electron rocket, set to make its debut later this year. “This is really all about scaling,” he said. “The funding is all about producing the vehicle in much more significant numbers.”

They say they will make their first launch in the coming months, but remain vague about specific dates.

Republican healthcare bill faces defeat in House

4:26 pm

It appears the Republican leadership lacks the votes in the House needed to pass its Obamacare replacement bill.

It appears that the Freedom Caucus in the House is generally holding firm, with more than 21 members agreeing that this is a bad bill, just as bad as Obamacare. Why vote for it, and make yourself a partner in this bad business? Consider for example this quote:

Rep. Rod Blum (R-Iowa), one of the few Freedom Caucus members who has a close relationship with GOP leadership, said Trump’s remarks in conference — and the building pressure — just “steels my resolve.”

“The way it stands right now, no,” he would not vote for the bill, Blum told POLITICO. “Not because of the Freedom Caucus, but because I’m a free-marketer and I’m a businessman. … And the present bill doesn’t give us a free market. I want health insurance premiums to come down. … This bill doesn’t give us a free market.”

The Republican leadership was able to successfully pass numerous full repeals of Obamacare when Obama was president and could veto them. Now that we have Trump, a president who will sign a repeal, they suddenly seem incapable of finding where they put those repeal bills. Very shameful.

Repeal the thing. Cleanly. This is what the American people want. They will thank you for it.

The changes seen by Rosetta on Comet 67P/C-G

1:51 pm

A new study released today describes in detail the many changes seen by scientists in the data collected by Rosetta during its two years in close proximity to Comet 67P/C-G.

“We saw a massive cliff collapse and a large crack in the neck of the comet get bigger and bigger,” said El-Maarry. “And we discovered that boulders the size of a large truck could be moved across the comet’s surface a distance as long as one-and-a-half football fields.”

In the case of the boulder, Rosetta’s cameras observed a 282-million-pound (130-million-kilogram), 100-feet-wide (30-meter) space rock to have moved 150 yards (460 feet, or 140 meters) from its original position on the comet’s nucleus. The massive space rock probably moved as a result of several outburst events that were detected close to its original position.

The warming of 67P also caused the comet’s rotation rate to speed up. The comet’s increasing spin rate in the lead-up to perihelion is thought to be responsible for a 1,600-foot-long (500-meters) fracture spotted in August 2014 that runs through the comet’s neck. The fracture, which originally extended a bit longer than the Empire State Building is high, was found to have increased in width by about 100 feet (30 meters) by December 2014. Furthermore, in images taken in June 2016, a new 500- to 1,000-foot-long (150 to 300 meters) fracture was identified parallel to the original fracture.

“The large crack was in the ‘neck’ of the comet — a small central part that connects the two lobes,” said El-Maarry. “The crack was extending–indicating that the comet may split up one day.”

It is almost a shame that Rosetta did not see that break-up. The images would have been breath-taking, and the science learned priceless.

The rings of Saturn

9:38 am

The rings of Saturn up close

Cool image time! The image to the right, cropped to post here, is part of one of the closest and highest resolution images that Cassini has yet taken of Saturn’s rings. The image was taken in January during one of the spacecraft’s ring grazing orbits, and has a resolution of 2,300 feet per pixel. And yet, as noted by the Cassini science team, “Even at this level of detail, it is still not fine enough to resolve the individual particles that make up the ring.”

In prepping the image, all I did was crop it to show the closest rings. I purposely did not reduce its resolution, so that you can see that no individual particles are visible. The rings of Saturn are truly made up of billions of small objects, behaving in many ways like liquid floating in the gravity well of Saturn. If you don’t believe me, download the full image and zoom in on it as much as you like. All you will see are pixels.

The fundamental science question therefore is not how Saturn’s rings behave (though this is certainly important and quite fascinating) but why did those rings end up the way they are. No other planet has rings anything like Saturn’s in their density and make-up. Why? Are Saturn’s rings a normal process that only occurs for short times around planets, which is why only Saturn has these types of rings at present? Or is it a rare event, so rare that we happen to be very lucky to see such a thing at all?

Even more important, Saturn’s rings and their behavior are likely linked closely to the same phenomenon that describe the formation of planets around a star. The more we can learn about why these rings exist, the more we will learn about why planets exist, both here circling the Sun as well as around stars everywhere else.

Trump signs NASA authorization

9:16 am

President Trump today signed the NASA authorization bill, initially written and sponsored by Senator Ted Cruz.

The most significant aspect of this authorization is what is not in it. The bill outlines what Congress wants NASA to focus on, and makes literally no mention of any Earth science research at all. Essentially, it tasks NASA to focus on space exploration, and space exploration only.

In many ways this is merely a symbolic act, since it is the budget that really determines what NASA will do, and the budget that Trump put forth last week only cut NASA’s Earth science budget by 5%. Nonetheless, the authorization bill gives us a sense of where the politics are heading. I expect that by the time Congress gets done with NASA’s budget there will be more cuts to that Earth science budget.

SpaceX signs lease for Florida warehouse to refurbish 1st stages

6:29 pm

The competition heats up: SpaceX has signed a five year lease for a Florida warehouse near Port Canaveral store and refurbish its recovered Falcon 9 and Falcon Heavy first stages.

This lease just firms up the reality that SpaceX is shifting from expendable first stages to a fleet of reusable first stage. Any rocket company that does not do the same is going to be left in the dust.

Ariane 5 launch delayed by labor strike

4:06 pm

The launch of two communications satellites on an Ariane 5 was delayed today by a strike at Arianespace’s French Guiana spaceport.

A work stoppage at the Ariane 5 rocket’s launch base in South America prevented rollout of the booster to the launch pad Monday, pushing back the liftoff of two communications satellites for Brazil and South Korea until at least Wednesday.

The fully-assembled launcher was set to roll out of the final assembly building Monday morning for the 1.7-mile (2.7-kilometer) journey to the ELA-3 launch zone at the Guiana Space Center. Arianespace officials were aiming for a launch attempt Tuesday evening.

But the rollout did not happen due to a “social movement” at the spaceport, according to Arianespace. Officials blamed the postponement on a strike among a segment of the workforce at the Guiana Space Center, which is managed by CNES, the French space agency, with support from the European Space Agency and numerous European contractors.

The article suggests that this was not a sanctioned strike, based on the expiration of a contract. Instead it appears to have been a wildcat strike, created to apply the most pressure in order to blackmail the company into giving the strikers more money. If so, and if Arianespace agrees to terms, its labor relations in French Guiana are going to decline quickly.
