Senator Bill Nelson (D-Florida) on Monday attacked the House version of NASA’s budget that required the agency to make a quick decision on its commercial manned launch company.

Nelson faces a difficult election campaign from the right. Thus, I suspect he has realized that he is better off promoting free enterprise than local pork. It is unfortunate that the Republicans in the House haven’t yet realized this.

An engineer has proposed in great detail building the USS Enterprise for the purpose of exploring the solar system.

8:58 am

If you build it they will come: An engineer has proposed using the USS Enterprise from Star Trek as a model for building an interplanetary spaceship for exploring the solar system.

Though similar in scale and appearance to the USS Enterprise (“it ends up that this ship configuration is quite functional,” Dan writes), the “Gen1 Enterprise” would be functionally very different. Firstly, the main nuclear-powered ion engine (boasting 1.5 GW of power) would strictly limit the Enterprise to intra-solar system missions, being incapable of anything approaching faster-than-light speeds. However, Dan claims that the Gen1 would be capable of reaching Mars from Earth within ninety days, and reaching the Moon in three.

The website is Build the Enterprise.

The assembly of the first test vehicle of XCOR Aerospace’s Lynx suborbital craft has begun.

The competition heats up: The assembly of the first test vehicle of XCOR Aerospace’s Lynx suborbital craft has begun.

I will admit to great deal of skepticism about this particular space company. Somehow XCOR always manages to get a great deal of coverage in the space community press, despite what I see as lack of any actual space-related results.

I could be wrong however, and if so, I will be the first to celebrate. This article suggests they might finally start test flights by the end of this year.

SpaceShipTwo to resume flight tests in June after a nine month hiatus.

SpaceShipTwo to resume flight tests in June after a nine month hiatus.

The long pause in flight tests, as well as the apparent delays in flying the ship with its rocket engine, suggest that there have been engineering issues with the ship and engine that Scaled Composites hasn’t revealed. Hopefully the resumption of testing is an indication that these issues have been overcome.

ATK today announced that it is building its own manned capsule for its Liberty solid rocket.

6:58 pm

The competition continues to heat up: ATK today announced that it is building its own manned capsule for its Liberty launch system.

The capsule’s first two flights are scheduled in 2014, both abort tests, followed in 2015 by an orbital flight and, finally, a crewed orbital flight. The spacecraft is designed for ten flights each, and ATK plans to build a minimum of four capsules. All flights will be launched by the Liberty launcher, and ATK is not actively exploring adapting the capsule for other [launch vehicles].

Liberty is based on the upgraded shuttle solid rocket boosters that were developed for the Ares rocket, now cancelled.

Europe has decided to build a probe, dubbed JUICE, to study Ganymede, Callisto and Europa, Jupiter’s big icy moons.

Europe has decided to build a probe to study Ganymede, Callisto and Europa, Jupiter’s big icy moons.

Known as JUICE, the Jupiter Icy Moons Explorer, the probe will enter orbit around the gas giant planet in 2030 for a series of flybys of Ganymede, Callisto and Europa. JUICE will brake into orbit around Ganymede, Jupiter’s largest moon, in 2032 for at least one year of close-up research.
