The Russians have now rescheduled for September 30 the next Proton rocket launch.

The competition heats up: The Russians have now rescheduled for September 30 the next Proton rocket launch.

The Russian Proton rocket’s return to flight following its spectacular July 2 failure has been rescheduled for Sept. 30 following a review of a first-stage valve issue and discussions between the Russian and Kazakh governments over launch safety issues.

They claim the main reason for the delay was the issues of clean-up following the July 2 launch crash, but that “first-stage valve issue” intrigues me. They have been very closed-mouth about it, yet it very clearly existed.

A lot of famous people have bought tickets to fly on Virgin Galactic’s SpaceShipTwo but not William Shatner: He’s apparently afraid of flying!

A lot of famous people have bought tickets to fly on Virgin Galactic’s SpaceShipTwo but not William Shatner: He’s apparently afraid of flying!

That’s according to Richard Branson. Shatner says instead that it’s the price of the ticket. “He wanted me to go up and pay for it and I said, ‘Hey, you pay me and I’ll go. I’ll risk my life for a large sum of money’. But he didn’t pick me up on my offer.”

Engineers have pushed the four orbiting Cluster satellites into their closest configuration yet.

9:45 am

Flying in formation: Engineers have pushed the four orbiting Cluster satellites into their closest configuration yet.

In an orbital reconfiguration that will help to maintain the mission’s life span, two of the four satellites achieved their closest-ever separation on 19 September, closing to within just 4 km of each other as they orbited at up to 23 000 km/h high above Earth. “We’re optimising the Cluster formation so that the separation between Cluster 1 and the duo of Cluster 3 and 4 – which are on almost identical orbits – is kept below 100 km when the formation crosses Earth’s magnetic equator,” says Detlef Sieg, working on Cluster flight dynamics at ESA’s ESOC operations centre in Darmstadt, Germany.

This close formation will provide scientists better data, as they are finding that the Earth’s magnetosphere is far more complex than expected.

Arianespace has signed a contract to build 18 more Ariane 5 rockets.

9:13 am

The competition heats up: Arianespace has signed a contract to build 18 more Ariane 5 rockets.

This order takes the number of Ariane 5 launchers in production for Arianespace to 38, and guarantees the continued provision of launch services for the European operator’s customers at the Guiana Space Centre through to the end of the decade.

Without doubt Arianespace is now in a solid position through the end of the decade. What will happen to them, however, when Falcon 9 and other cheaper rockets begin to fly regularly will be the real story. They have not yet found a way to cut their costs.

Voyager 1’s future.

9:08 am

Voyager 1’s future.

Voyager 1 has enough nuclear fuel to keep doing science through to 2025, and then it will be dead, adrift. On its current trajectory, the probe should eventually end up within 1.5 light years of a star in Camelopardalis, a northern constellation that looks like a cross between a giraffe and a camel. No one knows if there are any planets around that star, nor if aliens will be in residence by the time the probe arrives. “But if they are there, maybe they will capture Voyager 1,” says mission scientist Tom Krimigis of Johns Hopkins University in Baltimore, Maryland.

In addition to the above silliness, the article gives a good summary of the real data that Voyager 1 is sending back about interstellar space.

An unmanned spacecraft designed to get rid of space junk is set to launch in 2018, and use a new European built reusable launch system.

The competition heats up: An unmanned spacecraft designed to get rid of space junk is set to launch in 2018, and use a new European built reusable launch system.

Both components of this story are significant. First, a company has gotten the necessary financing to build the spacecraft, proving that there is profit to be made in the removal of space junk. Second, the launch system is simple and reusable, and will lower the cost of getting small payloads into orbit significantly. And it appears it is being built.

India space officials have decided to completely replace the second stage of the GSLV rocket that leaked during the rocket’s scrubbed launch last month.

8:36 am

India’s space agency has decided to completely replace the second stage of the GSLV rocket that leaked during the rocket’s scrubbed launch last month.

“Although the exact reasons for the leakage in the second stage of the engine, which prevented the launch on August 19, are being probed by the team headed by K Narayanan, it has been decided that a new liquid second stage (GS-2) will be assembled to replace the leaked stage,” said the official. He added that the process of assembling has begun, and that besides the GS-2, all the four liquid strap-on stages are being replaced with new ones.

That leak must have been quite significant for them to make this decision.

The astronauts who returned to Earth from ISS on September 10 were flying blind.

5:30 pm

Another Russian space glitch: The astronauts who returned to Earth from ISS on September 10 were flying blind.

The altitude sensors apparently failed soon after undocking. Since the Soyuz craft is not piloted but returns to Earth automatically, this failure was not crucial. That it happened, however, sends another worrisome signal about declining Russian quality control standards. If this system failed, why couldn’t another more crucial one fail as well?

When will SpaceX launch the upgraded Falcon 9? We have competing news stories:

When will SpaceX launch the upgraded Falcon 9? We have competing news stories:

  • The Canadian Space Agency sent out a press release today saying Cassiope will launch on September 15 on its Falcon 9 rocket.
  • Elon Musk sent out a twitter report of yesterday’s static fire test, noting there were anomalies and that the launch date is still to be determined.

This is very puzzling. That the Canadian release was sent out today suggests that they have information we don’t have about the static fire test and thus knew they could announce the launch date. That Musk is more circumspect however suggests that the information the Canadians have is not correct.

Update: Stephen Clark at Spaceflight Now has more information. It appears the launch will not happen on Sunday, as SpaceX plans a second launchpad static test tomorrow to iron out the unexplained “anomalies” in yesterday’s static test.

SpaceX successfully completed a static test of the 9 first stage engines of its upgraded Falcon 9 rocket today.

SpaceX successfully completed a static test of the 9 first stage engines of its upgraded Falcon 9 rocket today.

SpaceX’s upgraded Falcon 9 rocket briefly fired nine Merlin 1D engines on the launch pad Thursday, but engineers will review data from the prelaunch static fire test before confirming the mission’s targeted Sunday launch from Vandenberg Air Force Base in California, sources familiar with SpaceX’s launch preparations said.

NASA has announced a press conference for later today about the Voyager spacecraft.

9:26 am

NASA has announced a press conference for later today about the Voyager spacecraft.

The rumors are that all the scientists involved with this data from this spacecraft now finally agree that Voyager has left the solar system. More to come.

The rumors were true: NASA has confirmed that Voyager 1 is out of the solar system and in interstellar space, and has been since last summer.
