It was one of the most incredible displays ever seen - yet only a handful of rovers and spacecraft were there to witness it.

Nasa has revealed the data its spacecraft gathered whenComet Siding Spring, which passed just 87,000 miles(139,500 km) by Mars on Oct. 19.

Experts describe the scene, with thousands of shooting stars per hour and the entire sky changing colour as 'mind blowing'.

Geyer won't say how much contracting out this first test flight to Lockheed Martin is saving taxpayers, though he did say it makes financial sense. He said Lockheed has expertise in areas that NASA "doesn't need to get in the middle of."

"They know how to integrate rockets. They've built rockets," he said. "So we contracted with them and we said, 'Look, I'm going to give you these objectives. I want you to test the heat shield, I want you to test the avionics. I want you to test the parachutes.'"

Lockheed and the United Launch Alliance, which is providing the rocket, even took an unusual step for a NASA space flight and licensed both the launch and re-entry with the Federal Aviation Administration. After this flight, however, NASA will take the lead.

Much of Orion borrows from the Apollo and space shuttle systems, but not everything.

"The shape is very similar to Apollo, because the physics haven't changed," Geyer said.

However, Hawes said, "Everything inside is new."

Changes include using composite materials that lighten the craft and a new cockpit reducing the 300 switches from Apollo to about 50 for Orion. Some components were created using 3-D printing.

If all goes well, another test flight will be going into a very high orbit around the moon, which will include a service module built by Airbus, and by 2021, a manned mission. NASA is less interested in returning to the moon and more interested in reaching an asteroid, towing it into lunar orbit, and using it as a potential base from which to go to Mars.

Currently the Orion program is budgeted for about $1 billion a year. Geyer hopes that continues, but he and everyone may be feeling more pressure than ever to see next month's test succeed, given failures elsewhere.

NASA readies Orion for 'first step to Mars'

KENNEDY SPACE CENTER NASA is preparing to launch its next-generation, deep-space capsule Orion next month on its first spaceflight, a mission that a NASA administrator Thursday called "our first step in our journey to Mars."

At a briefing, Deputy Associate Administrator William Hill and other NASA and industry officials outlined hopes and expectations for a mission Dec. 4 that will blast an unmanned Orion capsule from Kennedy Space Center, sending it 3,600 miles into space and back for a splashdown off Baja California, Mexico.

The flight, which will involve two Earth orbits and last less than five hours, will give NASA and its Orion business partner, Lockheed Martin, their first space test of the capsule envisioned as a critical part of any NASA trips to the moon, an asteroid, Mars or beyond.

Those missions are not envisioned until the 2020s and 2030s, and even the first manned flight of Orion is not expected before 2021.

For the Dec. 4 test, Orion will be staged on top the most powerful rocket available in the world today, a three-booster Delta IV Heavy, provided by United Launch Alliance. As launched, the capsule will be fully configured to carry four crew members although it will be unoccupied.

All the tests and research NASA will be conducting on the flight will be with the assumption that there are astronauts on board.

The launch is set for 7:05 a.m., with Dec. 5 and 6 available as backup launch days.

The mission will test Orion's capabilities ranging from the 17 separations that will occur as various parts of the rocket and capsule system fall away, to the computers' ability to withstand space radiation, to the heat shield's and parachutes' operations for re-entry and splashdown. The test flight will cost about $370 million including the rocket, but not including the capsule, which NASA and Lockheed Martin intend to recover and reuse.

Orion will go 3,600 miles into space by comparison, the International Space Station orbits the Earth just 260 miles away so that it can built up to a top speed of 20,000 mph on its return. That's almost as fast as it would have to go for a journey to the moon.

NASA's Orion Flight Director Mike Sarafin called the mission Orion's "trial by fire."

NASA Rocket Experiment Finds the Universe Brighter Than We Thought

A NASA sounding rocket experiment has detected a surprising surplus of infrared light in the dark space between galaxies, a diffuse cosmic glow as bright as all known galaxies combined. The glow is thought to be from orphaned stars flung out of galaxies.

This is a time-lapse photograph of the Cosmic Infrared Background Experiment (CIBER) rocket launch, taken from NASA's Wallops Flight Facility in Virginia in 2013. The image is from the last of four launches. Image Credit: T. Arai/University of Tokyo

The findings redefine what scientists think of as galaxies. Galaxies may not have a set boundary of stars, but instead stretch out to great distances, forming a vast, interconnected sea of stars.

Observations from the Cosmic Infrared Background Experiment, or CIBER, are helping settle a debate on whether this background infrared light in the universe, previously detected by NASA's Spitzer Space Telescope, comes from these streams of stripped stars too distant to be seen individually, or alternatively from the first galaxies to form in the universe.

"We think stars are being scattered out into space during galaxy collisions," said Michael Zemcov, lead author of a new paper describing the results from the rocket project and an astronomer at the California Institute of Technology (Caltech) and NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. "While we have previously observed cases where stars are flung from galaxies in a tidal stream, our new measurement implies this process is widespread."

Using suborbital sounding rockets, which are smaller than those that carry satellites to space and are ideal for short experiments, CIBER captured wide-field pictures of the cosmic infrared background at two infrared wavelengths shorter than those seen by Spitzer. Because our atmosphere itself glows brightly at these particular wavelengths of light, the measurements can only be done from space.

"It is wonderfully exciting for such a small NASA rocket to make such a huge discovery," said Mike Garcia, program scientist from NASA Headquarters. "Sounding rockets are an important element in our balanced toolbox of missions from small to large."

During the CIBER flights, the cameras launch into space, then snap pictures for about seven minutes before transmitting the data back to Earth. Scientists masked out bright stars and galaxies from the pictures and carefully ruled out any light coming from more local sources, such as our own Milky Way galaxy. What's left is a map showing fluctuations in the remaining infrared background light, with splotches that are much bigger than individual galaxies. The brightness of these fluctuations allows scientists to measure the total amount of background light.

To the surprise of the CIBER team, the maps revealed a dramatic excess of light beyond what comes from the galaxies. The data showed that this infrared background light has a blue spectrum, which means it increases in brightness at shorter wavelengths. This is evidence the light comes from a previously undetected population of stars between galaxies. Light from the first galaxies would give a spectrum of colors that is redder than what was seen.

NASA's Real Life 'Interstellar' Mission

Could the plot of the movie "Interstellar" happen in real life -- both the catastrophe or the solution?

In the film, which opens nationwide on Friday, the hope for the future of mankind rests in the hands of a group of astronauts who must find a new planet hospitable to human life after governments and economies collapse and food is scarce.

While the sci-fi mystery makes for an exciting Hollywood plot, NASA says it is "on the cusp" of solving the central quandary of the film.

"For thousands of years we've wondered if we could find another home among the stars. We're right on the cusp of answering that question," NASA said in a blog post addressing the mysteries of "Interstellar" space.

"Multiple NASA missions are helping us extend humanity's senses and capture starlight to help us better understand our place in the universe," the space agency said.

After the astronauts in "Interstellar" leave a dystopian Earth with Dust Bowl-like conditions, they're able to push the limits of human space travel by using a newly discovered wormhole to jaunt between galaxies in search of food and a planet that can save the human race.

The space-time shortcut offered by the wormhole is a real theory spearheaded by Caltech astrophysicist Kip Thorne, who consulted on the film regarding his research that it may be possible to stabilize a wormhole and cross in far reaches of space that might otherwise take eons to access.

In real life, one NASA spacecraft is actually on the verge of leaving the solar system. Voyager 1, which blasted off in 1977, finally edged its way into interstellar space in 2012. The spacecraft won't see another star for 40,000 years, according to NASA, showing just how many unknowns still exist in the universe.

Nasa has detected a surprising surplus of infrared light in the dark space between galaxies.

Baffled astronomers say the lights is a diffuse cosmic glow as bright as all known galaxies combined.

They believe it could be from orphaned stars flung out of galaxies.

This artist's concept shows a view of a number of galaxies sitting in huge halos of stars. The stars are too distant to be seen individually and instead are seen as a diffuse glow, colored yellow in this illustration. The CIBER rocket experiment detected this diffuse infrared background glow in the sky and found that the glow between galaxies equals the total amount of infrared light coming from known galaxies.
