Europe’s Galileo GPS constellation reaches 10 satellites

8:58 am

The competition heats up: A Soyus rocket today launched from French Guiana the 9th and 10th satellites in Europe’s competing GPS system.

This launch enhances competition in two ways. First it is a success of the Russian Soyuz rocket, launched from the European spaceport in South America, Second, it establishes a competing GPS system to the American system, which is great for everyone. Expect future GPS units to provide the capability to use both the systems, as well as the Russian Glonass system.

Engineers propose using SpaceX rocket and capsule to bring samples back from Mars

10:14 am

Engineering by powerpoint! Several NASA engineers have proposed using SpaceX’s Falcon Heavy rocket and an upgrade of its Dragon capsule to bring samples back from Mars.

The researchers have drawn up a plan that uses a modified version of SpaceX’s uncrewed Dragon cargo capsule, which has already flown six resupply missions to the International Space Station for NASA. The Red Dragon variant would include a robotic arm, extra fuel tanks and a central tube that houses a rocket-powered Mars Ascent Vehicle (MAV) and an Earth Return Vehicle (ERV).

Red Dragon would launch toward Mars atop SpaceX’s huge Falcon Heavy rocket, which is scheduled to fly for the first time next year. After a long deep-space journey, the capsule would touch down near the 2020 Mars rover (whose landing site has not yet been chosen). “Red Dragon can go anywhere the rover can go, as far as landing elevation and terrain,” Gonzales said. “We’re confident we could land in front of the rover and have it drive to us.”

Red Dragon’s robotic arm would then grab a sample from the rover’s onboard cache (assuming the 2020 rover does indeed carry its samples, rather than stash them someplace) and transfer it to a secure containment vessel aboard the ERV, which sits atop the MAV. If something goes wrong during this exchange, Red Dragon can simply scoop up some material from the ground using its arm. The MAV would then blast off from the center of the capsule, like a missile from a silo, sending the ERV on its way back to Earth. The ERV would settle into orbit around our planet; its sample capsule would then be transferred to, and brought down to Earth by, a separate spacecraft — perhaps another Dragon capsule.

I like this concept because it uses available or soon-to-be available resources that are also relatively cheap to adapt for the mission. I also warn everyone that this is, as I note above, engineering by powerpoint. It is a concept, hardly a real proposal. The track record of seeing these kinds of proposals by NASA actually happen is quite poor.

ULA and Blue Origin sign new agreement

10:04 am

The competition heats up: ULA and Blue Origin have signed a new agreement expanding the production of Blue Origin’s BE-4 engine for ULA’s new Vulcan rocket.

This agreement and the timing of its announcement, one day after news leaked that rocket engine manufacturer Aerojet Rocketdyne is making a bid to buy ULA, suggest that there are people in ULA that want to make sure the agreements with Blue Origin are set in stone should the purchase comes true.

Aerojet Rocketdyne makes $2 billion offer to buy ULA

11:11 pm

The competition heats up: Rocket engine-maker Aerojet Rocketdyne has reportedly made a $2 billion offer to buy the rocket company United Launch Alliance (ULA), a partnership of Boeing and Lockheed.

If this deal goes through, it will put the squeeze on Jeff Bezos’s Blue Origin, which presently has a contract to build rocket engines for ULA. Aerojet Rocketdyne had wanted that contract and had lost out. If they buy ULA, they could then kick Blue Origin out and take on the contract themselves.

I am honestly not sure what to make of this whole thing, however. It could be that Aerojet, having lost a number of contracts and faced with a significant lose in business, has decided it needs to become a rocket company to survive. It could also be that the corporate heads of ULA have decided that the company’s effort to replace its Delta and Atlas rockets with Vulcan is too risky, and they are better off taking the cash and running.

Or it could be any number of other reasons. We shall have to wait and see how this plays out.

Spaceport head says Lynx to launch in early 2016

9:18 am

The competition heats up: The president of the spaceport in Midland, Texas, said today that XCOR’s Lynx suborbital spacecraft will complete its first test launch in the second quarter of 2016.

My readers know that I have been very skeptical of XCOR. They also know, if they have read closely, that I would be thrilled if they proved me wrong and succeeded. I think we shall find out one way or the other next year.
