NASA has been doing something so collaborative and unique in inviting people to have their names etched into microchips aboard various spacecraft heading to Space, the first one to launch is onboard a gigantic United Launch Alliance Delta IV Heavy rocket. This is the Orion Mission’s first flight test for The Journey to Mars programme, and the first mission since Apollo to carry a spacecraft “built for humans” to go the furthest in space in over 40 years, and the first time NASA’s next-generation spacecraft is tested against the challenges of space, and the first operational test of a heat shield strong enough to protect against 4,000-degree temperatures.
NASA’s Orion Microchip for the Name in Space Initiative
But what makes this mission so special for a NASA Geek like me, is I’m on it, I registered, got accepted, got the certificate, got etched into that microchip above, and got the…sadly no T-Shirt just yet 😉
Orion Flight Test Name in Space
Messages to Bennu
The next one my ‘Name in Space’ is heading to is an asteroid…and then back to Earth. The Asteroid Bennu mission launches in 2016 onboard the agency’s robotic mission Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) spacecraft.
Part of the ‘Messages to Bennu!’ microchip will travel for more than two years at the 1,760 ft (500 metre) wide asteroid. The spacecraft will collect a sample of Bennu’s surface and return it to Earth in a sample return capsule. One microchip will be brought back to Earth. Another copy will remain in outer space long after the sample has landed.
Jason Dworkin, mission project scientist at Nasa, said
‘It is exciting to consider the possibility that some of the people who register to send their names to Bennu could one day be a part of the team that analyses the samples from the asteroid 10 years from now,’

The Journey to Mars

Of the two missions that I’ve got my Name in Space on, this one excites me the most, for its not since the Apollo missions have the NASA engineers and designers had to build the unknown, and some solutions they don’t even know how to figure out just yet.
This first flight test of Orion will have the expected splashdown under billowing parachutes into the Pacific Ocean, but this mission will also test many of the riskiest events Orion will see when it sends astronauts to an asteroid and onward toward Mars in the future.

NASA’s Comments on the Mission
“Orion is the exploration spacecraft for NASA, and paired with the Space Launch System, or SLS, rocket it will allow us to explore the solar system,” said Mark Geyer, program manager of Orion, which is based at Johnson Space Center in Houston.
While the Delta IV Heavy will send Orion on its flight test, SLS will launch the spacecraft on future missions.

The flight test also is a marker for NASA’s Kennedy Space Center in Florida transformation into a multi-user spaceport. The transformation kicked off in 2010 and has made steady progress. This flight represents the center’s ability to produce a spacecraft and launch configuration that works well using aspects of the new model for processing and launch.
“The team is enthused, it’s good to go flying,” said Bob Cabana, director of Kennedy. “It’s not just Orion and SLS, you have to tie it all together. It’s Orion, it’s SLS and its commercial crew. It’s all of that.”
NASA’s Orion program has arrived at a fulcrum point that will tell its designers and builders how it stacks up technically. It also will show that NASA is ready to take the next step on its journey into deep space – and ultimately to Mars.
So even though Orion is poised for a mere 4 1/2-hour, two-orbit mission without anyone on board, the cone-shaped craft needs to perform its roster of tasks well, including an all-important descent through Earth’s atmosphere and splashdown.

“Really, we’re going to test the riskiest parts of the mission,” Geyer said. “Ascent, entry and things like fairing separations, Launch Abort System jettison, the parachutes plus the navigation and guidance – all those things are going to be tested. Plus we’ll fly into deep space and test the radiation effects on those systems.”
The flight test begins at Space Launch Complex 37 at Cape Canaveral Air Force Station. A 2-hour, 39-minute launch window opens at 7:05 a.m. EST so the launch and recovery of the spacecraft after splashdown can both take place in daylight. Orion will lift off on the strength of a United Launch Alliance Delta IV Heavy, currently the largest rocket in America’s inventory. The three RS-68 engines will produce about two million pounds of thrust at liftoff, enough to push the 1.63 million pounds of spacecraft, rocket and cryogenic fuel straight up off the launch pad and into orbit.
The boosters on either side of the rocket will fall away about four minutes into the ascent. The center booster with the second stage and Orion on top continues on for about 90 seconds more before its fuel is burned up and it separates to fall back to Earth. From there the second stage will lift Orion while the structural support fairings around the simulated service module fall away, followed closely by the launch abort system.
At 17 minutes, 39 seconds following liftoff, the Orion and second stage will be in an initial orbit of 115 miles by 552 miles. The second stage will ignite again two hours into the flight to send Orion through the Van Allen radiation belts and to a peak altitude of 3,609 miles, some 15 times higher than the space station. This is going to be a key point in the test flight as instruments inside Orion record the radiation doses inside the cabin – critical data for mission planners considering the best way to safely send astronauts into deep space in the future. Orion’s cameras will be turned off during its passes through the belts to protect them.
Three hours, 23 minutes into flight, the Orion crew module will fly on its own following separation from its service module and the Delta IV Heavy second stage. The spacecraft will be aimed at Earth’s atmosphere and it will be up to Orion’s onboard computers to set the spacecraft in the right position so its base heat shield can bear the brunt of the intense reentry heat.

Hitting the atmosphere at 20,000 mph four hours and 13 minutes after launch, Orion will encounter about 80 percent of the heat it would endure during a return from lunar orbit with astronauts aboard. Ground controllers will lose contact with Orion for 2 1/2 minutes during re-entry when the spacecraft is surrounded by plasma. They should regain communications with the craft just before the forward bay cover is jettisoned in a process that will begin the parachute deployment. After about four hours, 23 minutes, Orion will be bobbing in the Pacific Ocean off the coast of Baja California as recovery forces move in.
Teams from NASA’s Ground Systems Development and Operations Program based at Kennedy will work with U.S. Navy and Lockheed Martin personnel to bring the spacecraft into the well deck of the USS Anchorage, an amphibious ship with a protective enclosure that will allow Orion to basically float onboard without having to be lifted by a crane. A second ship, the USNS Salvor, also will be on hand as a backup.
Many aspects of the mission point to a future as ambitious as any time in NASA’s 50-plus-year history.
With lessons learned from Orion’s flight test, NASA can improve the spacecraft’s design while building the first Space Launch System rocket, a heavy booster with enough power to send the next Orion around the moon for Exploration Mission-1. Following that, astronauts are gearing up to fly Orion on the second SLS rocket on a mission that will return humans to deep space for the first time in more than 40 years. These adventures will set NASA up for a future human missions to an asteroid and even on the journey to Mars.
“To be able to even think about going to an asteroid and to be able to think about this kind of exploration, that’s very exciting,” Cabana said. “I think there’s a genuine, positive atmosphere, and I don’t think it’s confined to just Kennedy. You go across all the NASA centers and I think the team is really excited about the future.”
And while all that work is happening on the ground, astronauts on the International Space Station will continue the groundbreaking research that is already adding to humanity’s understanding of everything from long-duration spaceflight to the continued experimentation on products and processes that improve life on Earth.
