Russian Progress Cargo Space Station Resupply Spacecraft Launches but has Problem

"In the early morning hours today a Russian Progress unmanned cargo spacecraft launched from Kazakhstan with supplies for the International Space Station (ISS). The launch appeared to be picture perfect until it reached orbit. At that time there was a communication issue. Controllers in Russia were unable to confirm 'deployment of navigational antennas or the repressurization of the manifolds in the propulsion system' according to NASA commentator Rob Navias."

Keith's note: We've added a video to this story which clearly shows the abnormal spinning that Progress is experiencing.

Keith's update: NASA UPDATE (4/29 9:50 a.m. EDT): Docking has been called off for the Progress 59 spacecraft. Russian flight controllers are continuing to assess the vehicle and what the plan going forward will be. Additional information will be provided as it becomes available.

ULA Unveils Next Generation Launch System with a Little Showmanship [With Video], SpaceRef Business

"At a news conference at the National Space Symposium in Colorado Springs, United Launch Alliance (ULA) CEO Tory Bruno unveiled their Next Generation Launch System (NGLS) with a crowdsourced new name, Vulcan.

Showing some of the showmanship that Elon Musk of SpaceX has been known for, Bruno tried to follow in Musk's footsteps ratcheting up the marketing hype to a level not seen in recent years at a ULA event."

Marc's Note: Competition is good. It's good for both companies, it's good for America, it's good as it should eventually drive down costs. The question is, can ULA really compete? Can they adapt from their culture to a something like a SpaceX silicon valley culture? It should be fun to watch.

NASA SpaceX CRS-6 Pre-Launch News Briefings [Watch]

"Today, a Falcon 9 rocket will launch from Space Launch Complex 40 (SLC-40), Cape Canaveral Air Force Station, Florida on the 6th SpaceX cargo resupply mission to the International Space Station (ISS). Yesterday, NASA held three news briefings to discuss the mission and research on the ISS."

Marc's note: At the briefing, SpaceX's Hans Koenigsmann was asked what the probability of success for the Falcon 9 first stage landing on the drone ship. His response was 75% and then he said perhaps 80%. It seems SpaceX is quite a bit more confident on this third attempt.

Marc's update: The launch was scrubbed until Tuesday at 4:10 pm EDT due to weather. The weather forecast for tomorrow is 50-50.
