Boeing and SpaceX getting NASA money for manned space launches [Updated]

Science Focus

SpaceX's Dragon V2.

Today, NASA administrator Charles Bolden announced that there were two winners in the campaign to become the first company to launch astronauts to low-Earth orbit: Boeing and SpaceX. The two will receive contracts that total $6.8 billion dollars to have hardware ready for a 2017 certification—a process that will include one crewed flight to the International Space Station (ISS).

In announcing the plan, Bolden quoted President Obama in saying, "The greatest nation on earth should not be dependent on any other nation to get to space." And he promoted the commercial crew program as a clear way of ending a reliance on Russian launch vehicles to get to the ISS. But Bolden and others at the press conference were also looking beyond that; several speakers, including Kennedy Space Center Director Bob Cabana and astronaut Mike Fincke, mentioned that the ultimate goal is Mars.

To that end, Bolden emphasized that NASA is still doing its own vehicle and rocket development. The Orion crew capsule, intended to be suitable for missions deeper into the Solar System, recently underwent a splashdown test in the Pacific. Its first test flight aboard a Delta IV rocket is scheduled for this December. Work on the Space Launch System, a heavy lift vehicle that can transport the additional hardware needed for deep space missions, was also mentioned.

Monogram, M106 Spiral Galaxy, Canes Venatici Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: monogram initials, star galaxies, outer space picture, deep space astronomy, hubble galaxy photography, supermassive black hole, spiral arms, constellation canes venatici, hunting dog stars, m106cv, messier 106, seyfert ii galaxy

Galaxies, Stars and Nebulae series Messier 106 (also known as NGC 4258) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy, which means that due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center.

Mars, Antares, Moon and Saturn

more »
Mars, Antares, Moon, and Saturn are the brightest celestial beacons in this serene sky. The Sun's golden light is still scattered along the southwestern horizon though, captured after sunset on September 28. The evening gathering of wandering planets and Moon along with the bright star viewed as an equal to Mars and the Scorpion's Heart was enjoyed around planet Earth. But from the photographer's perspective looking across the calm waters of Lake Balaton, Hungary, they were joined by a more terrestrial sailboat mast light. Mast light, bright star, planets and Moon are all posing near the plane of the ecliptic.

War and Peace Nebula Wall Graphic

Here's a great wall decal featuring a beautiful image from deep space


tagged with: pismis 24, star cluster, stars, nebula, ngc 6357, emission nebula, cosmology, astronomy, starcluster, space, universe, astronomer, war and peace nebula, nebulae, nebulas

NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding "cocoons". This nebula was given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance. They said that in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull. This nebula includes the open cluster Pismis 24, which is home to several massive stars. One of the brightest stars in the cluster, Pismis 24-1, was thought possibly to be the most massive on record, approaching 300 solar masses, until it was discovered to be a binary system with each star exceeding 100 solar masses.

NASA's SDO watches giant filament on the sun

more »

A snaking, extended filament of solar material currently lies on the front of the sun -- some 1 million miles across from end to end. Filaments are clouds of solar material suspended above the sun by powerful magnetic forces. Though notoriously unstable, filaments can last for days or even weeks.

Crumpled graphene could power future stretchable electronics

more »

When someone crumples a sheet of paper, that usually means it's about to be thrown away. But researchers have now found that crumpling a piece of graphene "paper" -- a material formed by bonding together layers of the two-dimensional form of carbon -- can actually yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices.

This image from ESO’s VISTA telescope captures a celestial landscape of vast, glowing clouds of gas and tendrils of dust surrounding hot young stars. This infrared view reveals the stellar nursery known as NGC 6357 in a new light. It was taken as part of the VISTA Variables in the Vía Láctea (VVV) survey, which is currently scanning the Milky Way in a bid to map our galaxy’s structure and explain how it formed.
