A year ago, Virgin Galactic lost its SpaceShipTwo in an accident that killed one pilot,
VG is moving on, however. It has nearly completed a new SpaceShipTwo, and it is developing LauncherOne, a rocket that will deliver small satellites to orbit at low cost. It's also working with DARPA to develop the XS-1, a reusable spaceplane.

Molecular Oxygen In Comets
The Rosetta spacecraft has found molecular oxygen in the comet it's studying.
Since oxygen is so reactive, that's a surprise. Our picture of the early Solar System may have to change.

Close To Ceres
NASA's Dawn spacecraft is backing into it's final orbit, 230 miles out from the dwarf planet Ceres.
From there, the probe will gather its most detailed data, hopefully explaining mysteries like Ceres' two bright spots.

Alien Megastructure
Astronomers are confident they'll be able to determine whether a huge structure orbits a star 1,500 light years away by observing the next dimming event.
Now, we wait.

Pricey Tick Tock
A wristwatch worn on the Moon by David Scott during the Apollo 15 mission sold at auction for $1.6 million last week.

Life On Earth
Scientists studying nearby comets and the proto-planetary disks of distant stars suggest the basic ingredients of life were on Earth from the beginning.
That, in turn, suggests they have been present on many worlds.

2015 TB145
The asteroid 2015 TB145 will zip past Earth Halloween night just beyond the Moon's orbit. It's the latest exhibit in the case for a planetary defense capability.
Judging by its orbit, this asteroid might actually be a comet.

Exoplanet Gobbling
Astronomers are now watching a white dwarf 520 light years away dismantling a small world in orbit about it, using the star's powerful gravity.
The whole process should take about a million years.

Crust Porosity And Life
Scientists think life may have arisen on Earth in subsurface niches created by the pounding of the planet by comets and asteroids during the Late Heavy Bombardment.
Studying the lunar crust, therefore, might tell us something about how life begins.

ATA On The Case
The SETI Institute's Allen Telescope Array is now scanning the star system that could conceivably contain an alien megastructure, searching for possible intelligent radio signals.
The leading explanation for the odd set of transits documented by the Kepler spacecraft is a clump of giant comets, but the alien option must be ruled out, if possible. ATA won't do that, of course-- the absence of radio signals would not mean a structure is not there-- but the discovery of signals would be quite something.

Lunar Fueling
A new study argues Mars-bound manned ships should be launched from Earth basically without fuel. The ship would fly to a fuel depot at a Lagrange point in the Earth-Moon system to be fueled for the trip to Mars using rocket fuel processed from lunar water.
The idea is to lower the cost of launching from Earth by reducing the mass launched.

Possibly Alien
The Kepler spacecraft has detected an unusual pattern of transits across the disk of a star 1,500 light years away. It's an F-type star, so slightly larger than the Sun. So far, astronomers have been unable to imagine a natural explanation. The spacecraft instruments check out.
Is there, therefore, an artificial explanation? Could a huge structure built by an advanced civilization be orbiting that star? SETI researchers have been called in to listen for possible radio signals coming from that star.

Habitability Index
A new study has developed a habitability index to rank the potential of alien worlds to support life.
The index takes various factors into account, not just the distance of the planet from its parent star. It will also become more useful the more we learn.

Gale Lakes
A new study suggests lakes of water existed for extended periods early on in Gale Crater on Mars, improving the odds that life could have developed and survived for perhaps tens of millions of years.
The study uses data gathered by the Curiosity rover as it has traversed the floor of Gale.

Double Base
In the early phase of settling the Moon, pairing a public, government-run base with a private, commercial base nearby might make sense.
Such an approach would increase safety for astronauts, allow joint projects, and expand the human economy into space in a major way.

Ballooning To Space
World View, an Arizona-based company, is planning to offer tourists flights to 100,000 meters altitude in a gondola under a huge helium balloon starting in 2017.
Passengers will spend about two hours at altitude, where they can see the blackness of space and the curvature of Earth. The pressurized gondola is classified by the FAA as a spacecraft.

Oxygen As Biomarker
Scientists have considered free oxygen in the atmosphere of a planet to be a sign of life. New research, however, establishes oxygen could be maintained nonbiologically.
So, to use oxygen as a bionarker, it must be in the right context.
