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.

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.

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.

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.

SpaceX successfully launches commercial satellite

11:40 pm

The competition heats up: SpaceX tonight successfully launched Echostar 23.

This launch is almost four weeks after their last launch, which sent a Dragon capsule to ISS. Their goal this year has been to do one launch every two weeks, a goal they have not yet reached. The next launch, which will also place a commercial communications satellite into orbit, is tentatively set for March 27, and will also be the first launch that reuses a first stage. If they make that happen it will be first time they have hit the two week launch rate this year. They will then try to follow with another Dragon resupply mission, this time reusing a Dragon capsule for the first time.

SpaceX wins another Air Force launch contract

8:56 pm

The competition heats up: SpaceX has been awarded a $96.5 million contract to launch an Air Force GPS satellite.

This price is about $14 million more than the last SpaceX Air Force launch contract. That’s probably because SpaceX was trying to undercut ULA’s price by as little as possible so that they could increase their profit. Until there are others in the business who can compete with SpaceX’s prices, the company is sitting pretty in any competitive bidding situation. Their costs are less, so they can always beat everyone else’s prices, while maximizing their profits.

Ukraine-Canadian partnership to launch from Nova Scotia

10:26 am

The competition heats up: A new launch company based in Canada and using a Ukrainian-made rocket called the Cyclone-4M has chosen as its launch site a location in Nova Scotia.

The rocket appears to be a variation of the Ukrainian Tsiklon-4 rocket, and would make this company competitive and in fact more capable than India’s smaller PSLV rocket that recently put 100 smallsats into orbit.

Parachute tests for Boeing Starliner

8:45 am

Boeing’s Starliner spacecraft has successfully completed a parachute test at New Mexico’s Spaceport America.

Uniquely, this test wasn’t conducted via the use of a helicopter of an aircraft – as seen with other vehicles, such as the Orion spacecraft. Boeing was not able to fit the Starliner test article into the hold of a C-130 or C-17 aircraft, so they instead used a 1.3-million-cubic-foot balloon, which is able to lift the capsule to its intended altitude.

The test went well, with Starliner released from the balloon, deploying two drogue parachutes at 28,000 feet to stabilize the spacecraft, then its pilot parachutes at 12,000 feet. The main parachutes followed at 8,000 feet above the ground prior to the jettison of the spacecraft’s base heat shield at 4,500 feet. Finally, the spacecraft successfully touched down.

The article once again makes note of NASA’s fake concern over the Atlas 5 rocket. The concern isn’t that the rocket isn’t reliable. The concern is that Boeing hasn’t yet gotten NASA’s certification that it is reliable. In other words, because NASA hasn’t signed a piece of paper stating the obvious fact that the Atlas 5 is safe, Boeing’s Starliner cannot be considered safe.

Decision on new Orbital ATK rocket expected in 2018

9:56 pm

The competition heats up? Orbital ATK says it will decide whether it will introduce a new commercial rocket sometime in early 2018.

Orbital ATK has released few details about what is known only as its “Next-Generation Launcher.” The vehicle would use solid-fuel lower stages based on space shuttle solid rocket motor segments developed by the company, as well as solid strap-on boosters. A liquid-oxygen, liquid-hydrogen upper stage would use a version of Blue Origin’s BE-3 engine that company is currently flying on its New Shepard suborbital vehicle.

The rocket’s design has at least superficial similarities to a vehicle concept called Liberty that ATK proposed prior to its merger with Orbital Sciences Corporation. Liberty, with a five-segment shuttle solid rocket booster first stage and a second stage derived from the Ariane 5 core stage provided by Astrium, was itself a commercial spinoff of the cancelled Ares 1 rocket from NASA’s Constellation program. ATK proposed Liberty for NASA’s commercial crew program but failed to win funding.

The decision itself will be based on whether the Air Force remains interested. At the present time the Air Force is investing about half the capital required to develop the rocket. If the Air Force backs out, Orbital ATK will decide against the rocket. If the Air Force support remains firm, they will go ahead with development. Essentially, this story is Orbital ATK lobbying to keep the Air Force support going.

Saturn’s weird moon Pan

9:34 am

Pan

New images from Cassini have provided scientists their first sharp images of Saturn’s moon Pan, and what those images show is something really weird. The image on the right is only one sample, with the link providing more.

Pan orbits in a gap between two rings, and the ridge might have accumulated from material from those rings. Then again, maybe not. It will take more data to I think completely unravel how this moon got to look like it does.

Congress micromanages rocket development at ULA

9:16 am

Corrupt Congress: Even though ULA favors Blue Origin’s BE-4 engine for its Vulcan rocket, various elected officials in Alabama are pushing the company to use Aeroject Rocketdyne’s AR-4 engine instead.

At the end of February, two US representatives, Mike Rogers of Alabama [Republican] and Mac Thornberry of Texas [Republican], decided to push a little harder. On February 28, they sent a letter to Lisa Disbrow, the acting secretary of the US Air Force, and James MacStravic, who is performing the duties of the undersecretary of defense for acquisition, technology, and logistics. In addition to reiterating a desire that ULA continue to fly a second rocket, the Delta IV Heavy, the letter urges the Pentagon officials to be skeptical about the BE-4 engine.

“The United States Government (USG) must have a hands-on, decision-making role… in any decision made by United Launch Alliance to down-select engines on its proposed Vulcan space launch system, especially where one of the technologies is unproven at the required size and power,” the letter states. “If ULA plans on requesting hundreds of millions of dollars from the USG for development of its launch vehicle and associated infrastructure, then it is not only appropriate but required that the USG have a significant role in the decision-making concerning the vehicle.” The letter then goes on to say the Air Force should not give any additional funding to ULA, other than for current launch vehicles, until the company provides “full access, oversight of, and approval rights over decision-making” in its choice of contractors for the engines on Vulcan.

The article also mentions porkmaster Senator Richard Shelby (R-Alabama), who also favors Aerojet Rocketdyne because they say they will build it in Alabama. Note also that these elected officials are not only trying to pick the winner in the private competition between these two rocket engines, they also want to force ULA to keep using the Delta rocket, even though it is very expensive and not competitive with the newer rockets being developed by other companies. And their only reason for doing so is because they provide jobs for their districts.

This one story illustrates perfectly the corruption that permeates both parties in Congress. While it is more likely that Democrats will play this pork game, there are plenty of corrupt Republicans who play it as well. These petty dictators all think they have the right to interfere in the private efforts of Americans, whether it involves building a new rocket or buying health insurance. And all we get from this is a poorer nation and a bankrupt federal government.

Stratolaunch to fly in 2017?

9:02 am

The competition heats up: In an interview Paul Allen has revealed that he hopes to begin flight tests of his gigantic Stratolaunch airplane, the largest ever built, later this year.

No word on the rocket that this air-launched system would launch, however. In fact, it appears that no one seems interested in providing one. This could change once the plane is flying.

Blue Origin signs second contract for New Glenn

11:33 pm

The competition heats up: One day after announcing its first launch contract, Blue Origin announced today a second contract for its New Glenn rocket.

In a tweet this morning, Blue Origin Founder Jeff Bezos said OneWeb has reserved five launches using the rocket, bringing to six the number of missions in the New Glenn manifest.

So far I can find no information about the prices being charged by Blue Origin for these launches. I suspect they are giving their customers discounts for being the first, but this is not confirmed yet.

At the crest

12:15 pm

Looking north at the crest

Cool images time! The image above, cropped and reduced to show here, is a panorama that I have created from the most recent images sent down from Opportunity yesterday. The rover sits on the crest of the rim of Endeavour Crater, and this panorama looks north at that crest, back in the direction where the rover has come. The rovers tracks can be seen fading away into the distance slightly to the left of the crestline..If you click on the picture you can see the full resolution image.

The crater floor is to the right, the plains that surround the crater are to the left.

Below is another panorama, created by me from the same images sent down today, this time looking south at the crest in the direction Opportunity is heading. Once again, if you click on the picture you can see the full resolution version.

The full set of today’s images from Opportunity suggest that the science team took them to assemble a full 360 degree panorama before they begin the journey south to the gully that is just now becoming visible at the southernmost edge of the most recent overhead traverse image. To get to that gully they will now have to descend off the crest and down outside the rim of Endeavour Crater, moving to the right in the panorama below. This is therefore their last opportunity for awhile to get a good view from a high overlook.
