Virgin Galactic Wants to Build a Supersonic Jetliner That’ll go Even Faster Than the Concorde

Virgin Galactic, the space tourism arm of Richard Branson’s multinational commercial empire (aka. the Virgin Group) has some bold plans for the future. In the past year, the company carried out two glide tests with their LauncherOne vehicle, completed two successful flight tests with their SpaceShipTwo vehicle, and unveiled the Gateway to Space – their space tourism hub at Spaceport America.

And last week (Monday, August 3rd), the company announced that it had entered into a partnership with engine-maker Rolls-Royce to build a supersonic commercial aircraft that would travel three times the speed of sound (Mach 3). If realized, the proposed aerospace vehicle will carry 19 passengers to altitudes of more than 18,000 meters (60,000 ft) while travelling at speeds 50% faster than the Concorde.

A Huge Ring-Like Structure on Ganymede Might be the Result of an Enormous Impact

Ganymede’s surface is a bit of a puzzle for planetary scientists. About two-thirds of its surface is covered in lighter terrain, while the remainder is darker. Both types of terrain are ancient, with the lighter portion being slightly younger. The two types of terrain are spread around the moon, and the darker terrain contains concurrent furrows.

For the most part, scientists think that the furrows were caused by tectonic activity, possibly related to tidal heating as the moon went through unstable orbital resonances in the past.

But a new study says that a massive impact might be responsible for all those furrows.

SpaceX is Hiring People to Help Build a Resort at the Boca Chica Launch Facility

SpaceX has been making some exciting moves this summer. On May 30th, their Crew Dragon spacecraft launched on its historic Demo-2 mission, carrying astronauts Robert Behnken and Douglas Hurley to the ISS. They safely returned again on August 2nd, shortly after the SN5 prototype conducted the long-awaited 150 m (500 ft) hop test at the company’s launch facility in Boca Chica, Texas.

And now, in a move that mirrors what Virgin Galactic is doing at Spaceport America in New Mexico, SpaceX has committed to turning Brownsville – the town nearest to the Boca Chica facility – into its own spaceport. To this end, SpaceX recently posted a job application on its website where they announced they are seeking a Resort Development Manager. Potential applicants should follow the link if they think they’re up to the task!

Hubble Examines Earth’s Reflection as an ‘Exoplanet’ During a Lunar Eclipse

Hubble eclipse

What would we look for in a distant exoplanet in the hunt for Earth-like worlds, and perhaps life? A recent observation carried out by the Hubble Space Telescope found tell-tale signatures from our home planet by looking at a familiar source under extraordinary circumstances: Earth’s Moon, during a total lunar eclipse.

Lava Tubes on the Moon and Mars are Really, Really Big. Big Enough to Fit an Entire Planetary Base

Could lava tubes on the Moon and Mars play a role in establishing a human presence on those worlds? Possibly, according to a team of researchers. Their new study shows that lunar and Martian lava tubes might be enormous, and easily large enough to accommodate a base.

Astronomers Think They’ve Found the Neutron Star Remnant From Supernova 1987a

In 1987, astronomers witnessed a spectacular event when they spotted a titanic supernova 168,000 light-years away in the Hydra constellation. Designated 1987A (since it was the first supernova detected that year), the explosion was one of the brightest supernova seen from Earth in more than 400 years. The last time was Kepler’s Supernova, which was visible to Earth-bound observers back in 1604 (hence the designation SN 1604).

Since then, astronomers have tried in vain to find the company object they believed to be at the heart of the nebula that resulted from the explosion. Thanks to recent observations and a follow-up study by two international teams of astronomers, new evidence has been provided that support the theory that there is a neutron star at the heart of SN 1604 – which would make it the youngest neutron star known to date.
