LightSail deploys its solar sails

10:48 pm

Though full confirmation will not come until later tonight, telemetry from LightSail suggests that its solar sails have successfully begun deployment.

Telemetry received on the ground showed motor counts climbing to the halfway point before LightSail traveled out of range. Power levels were consistent with ground-based deployment tests, and the spacecraft’s cameras were on. “All indications are that the solar sail deployment was proceeding nominally,” wrote mission manager David Spencer in an email update.

They will have to wait until the cubesat comes back in range at 2:46 am (Eastern) to see if the deployment completed successfully, as well as download images.

Bee die off hasn’t happened

11:39 am

The uncertainty of science: Despite numerous claims by environmentalists and scientists in the past decade that the bee population was dying off, new data from the Agriculture Department suggests that bee populations are now at a 20 year high.

The reason? It appears that beekeepers have been very innovative and creative when faced with disease or other problems that hurt bees. Driven by the profit motive and competition and free to act, they have come up with solutions.

LightSail back in business?

8:57 am

The Planetary Society’s solar sail engineering test called LightSail has re-established communications with the ground, allowing for the possibility that it can finally achieve its solar sail deployment, the main purpose of the mission.

I had previously reported that the sails had deployed, but a commenter correctly noted that only the panels have deployed, not the sails themselves, which need full battery power. The communications problem has been related to a battery charging problem. They are hoping that the batteries will get charged by mid-day today when they will try to deploy the sails.

Manned flights from Vostochny delayed

9:02 am

In order to save construction costs at its new spaceport at Vostochny, Russia has decided to delay its first manned flight there until 2023.

They originally were going prepare a launchpad for Soyuz rockets so that they could do a manned launch at Vostochny as early as 2019, but had already admitted this was inefficient and had abandoned the plan. Now they have admitted that it will take until 2023 for them to get Vostochny and Angara ready for manned flights.

That it will still take almost 8 years to prepare a launchpad and get Angara ready to launch manned capsules, however, seems an ungodly long period of time. It should not take that long.

Airbus unveils its first stage re-useability concept

2:32 pm

The competition heats up: Airbus unveiled today its prototype design to recover and reuse the engines and avionics of its Ariane rockets.

Herve Gilibert, technical director for Airbus’ Space Systems division, said the Adeline propulsion unit — engine and avionics — is where lies most of the value of the first stage. The Airbus team concluded that SpaceX’s design of returning the full stage to Earth could be simplified by separating the propulsion bay from the rest of the stage, protecting the motor on reentry and, using the winglets and turbofans, return horizontally to a conventional air strip. “We are using an aerodynamic shield so that the motor is not subjected to such high stress on reentry,” Gilibert said. “We need very little fuel for the turbofans and the performance penalty we pay for the Ariane 6 launcher is far less than the 30 percent or more performance penalty that SpaceX pays for the reusable Falcon 9 first stage.

Gee, for decades Arianespace and Boeing and Lockheed Martin and everyone else in the launch industry insisted it made no economic sense to try to recover and reuse the first stage of their rockets. Then SpaceX comes along and makes an effort to do so, without as yet even coming close, and suddenly everyone agrees it is economically essential to do it as well.

Isn’t competition wonderful?

LightSail deploys, then falls silent again

8:14 am

Though it appears that LightSail has successfully deployed its solar sail — the main objective of this engineering flight, the Planetary Society cubesat ceased communications shortly thereafter.

To confirm the success of the mission they need to re-establish communications, which they hope will happen when the spacecraft’s orbit exposes it to more sunlight and the battery gets charged.

Air Force asks private companies to develop new rocket engines

5:47 pm

The competition heats up: The Air Force has issued a request for proposals for the development of new rocket engines to replace the Russian engine used on the Atlas 5 rocket.

The press release is a little vague in that it seems to be calling for the development of this new engine, but it could also be interpreted as calling for the development of an entire rocket system. The amount of money involved is too small for this, however, so I suspect we are only talking about engine development here.

Meanwhile, they will continue to issue launch contracts to ULA and SpaceX while they wait for this new engine to be developed. Note also that this sure is a good deal for ULA, getting the Air Force to pay for upgrades to its Atlas 5 rocket.

ULA to trim management by 30%

10:31 pm

The competition heats up: In order to make itself more efficient and competitive, ULA has decided to cut its management by 30%.

ULA CEO Tory Bruno has said ULA must shrink to remain successful under reduced U.S. military budgets and with Elon Musk’s SpaceX (Space Exploration Technologies Corp.) being certified to compete against ULA for national security mission launches. “To achieve that transformation, we are reducing the number of executive positions by 30 percent and offered a voluntary layoff for those interested on the executive leadership team,” said ULA spokeswoman Jessica Rye. “It is important for ULA to move forward early in the process with our leadership selections to ensure a seamless transition and our continued focus on mission success.”

This news should be looked at in the context of a proposed Senate bill that requires the Air Force to significantly cut funding to ULA.

Not only would the bill cut an annual $1 billion payment from the Air Force to ULA, it would put severe restrictions on the number of Russian engines ULA could use in its Atlas 5, which in turn will limit the number of launches the Air Force can buy from the company.
