The second phase of NASA’s robotic refueling demo on ISS has successfully proven that a robot can remove a satellite fuel cap not designed for refueling.

The fuel cap design is a duplicate of that used by several climate research satellites presently in orbit. These satellites were not designed to be refueled, but if they could be refueled, their usefulness in orbit could be doubled, even tripled. This test is intended to demonstrate that a robot could refuel them.

The last phase of this robotic demo will take place in August, when the robots will attempt to pump a simulated fuel into the demo satellite.

NASA has delayed the first test flight of Orion’s launch abort system by two years to 2017.

NASA has delayed the first test flight of Orion’s launch abort system by two years to 2017.

NASA officials have been warning since last year that work on Orion would be slowed to keep pace with the development of SLS and its launch infrastructure. The agency has proposed trimming Orion’s $1.2 billion budget back to $1 billion for 2013. With the high-altitude abort test facing at least a budget-driven delay, the Langley team has proposed conducting one or more less-expensive tests in its place. Ortiz said conducting a hot-fire test in 2015 or 2016 would “keep the [launch abort system] project moving forward and help alleviate risk.”

I predict that Dragon will not only test its launch abort system first, it will have humans flying on it before Orion. And Dragon will do this for a fraction of the total cost that Orion and SLS spend per year. I also predict that when Dragon does this, Congress will finally begin noticing this disparity, and SLS will die unlaunched.

An asteroid that was discovered only four days before it flew by the Earth on June 14 has turned out to be much bigger than first thought.

An asteroid that was discovered only four days before it flew by the Earth on June 14 has turned out to be much bigger than first thought.

This particular asteroid may not have been a danger, but much of the concern was rooted in the late warning of its detection — 2012 LZ1 was spotted only four days before closest approach. One of the reasons for its late discovery is because it was detected in Southern Hemisphere skies, part of the world were we have few asteroid-watching programs. If it had been on a collision course with Earth, a few days notice is no time at all.

So, in the aftermath of the flyby, astronomers at the famous Arecibo Observatory in Puerto Rico used radar to image the interplanetary interloper (pictured top). What they uncovered was a surprise: Asteroid 2012 LZ1 is actually bigger than thought… in fact, it is quite a lot bigger. 2012 LZ1 is one kilometer wide (0.62 miles), double the initial estimate.

Excalibur Almaz has signed a deal to use Xcor’s Lynx suborbital craft to train its astronauts.

The competition heats up: Excalibur Almaz has signed a deal to use Xcor’s Lynx suborbital craft to train its astronauts.

Since Xcor has not yet flown Lynx, and Excalibur Almaz as a lot of work to do to make its Soviet-era modules flyable, I would bet that this news release is mostly public relations hype, centered as much on raising investment funds for both companies as it is about training astronauts.

SpaceShipTwo was in the air on Friday, as WhiteKnightTwo did a 1.5 hour test flight with the ship attached to its belly.

The competition heats up: SpaceShipTwo was in the air on Friday, as WhiteKnightTwo did a 1.5 hour test flight with the ship attached to its belly.

This was the second flight of WhiteKnightTwo in three days, and is in line with Virgin Galactic’s test flight schedule announced in May. If the test flights go well, expect that first rocket-powered flight of SpaceShipTwo later this year.

A new company has announced plans to use the Gemini capsule design from the 1960s to provide crew and cargo capability to orbit.

The competition heats up: A new company has announced plans to use the Gemini capsule design from the 1960s to provide crew and cargo capability to orbit.

“Since this is an existing and proven design we could begin construction six to eight weeks after funding and complete a flying prototype ten to thirteen months later,” said WestWind President Bill Jolly.

The FAA and NASA have worked out their differences concerning their regulation of private commercial space.

The FAA and NASA have worked out their differences concerning their regulation of private commercial space.

Essentially, NASA has finally conceded with this agreement that it has no control over a private space launch that is not flying to a NASA facility. That the FAA continues to have as much regulatory control is bad enough, but getting NASA out of the loop will at least ease the bureaucratic burden for private companies.

The new colonial movement: China is in its final preparations for the launch of its next manned mission, expected any day now.

This is the key quote from the article:

China aims to build a space station around 2020 based on the space rendezvous and docking technology that is currently being tested. Several components will be sent into space separately before being assembled into a space station through a variety of docking procedures.

Mars Odyssey put itself into safe mode on Friday when it detected problems with one of the three reaction wheels used to orient the spacecraft.

Mars Odyssey put itself into safe mode on Friday when it detected problems with one of the three reaction wheels used to orient the spacecraft.

If this space probe goes down, it will make it more difficult to rely data back from Opportunity, now on the Martian surface, and Curiosity, due to land in two months.
