News from Space: Orion Spacecraft Completed

orion_arrays1NASA’s return to manned spaceflight took a few steps forward this month with the completion of the Orion crew capsule. As the module that will hopefully bring astronauts back to the Moon and to Mars, the capsule rolled out of its assembly facility at the Kennedy Space Center (KSC) on Thursday, Sept. 11. This was the first step on its nearly two month journey to the launch pad and planned blastoff this coming December.

Orion’s assembly was just completed this past weekend by technicians and engineers from prime contractor Lockheed Martin inside the agency’s Neil Armstrong Operations and Checkout (O & C) Facility. And with the installation of the world’s largest heat shield and the inert service module, all that remains is fueling and the attachment of its launch abort system before it will installed atop a Delta IV Heavy rocket.

Orion-at-KSC_Ken-KremerThe unmanned test flight – Exploration Flight Test-1 (EFT-1) – is slated to blast off on December 2014, and will send the capsule into space for the first time. This will be NASA’s first chance to observe how well the Orion capsule works in space before it’s sent on its first mission on the Space Launch System (SLS), which is currently under development by NASA and is scheduled to fly no later than 2018.

The Orion is NASA’s first manned spacecraft project to reach test-flight status since the Space Shuttle first flew in the 1980s. It is designed to carry up to six astronauts on deep space missions to Mars and asteroids, either on its own or using a habitat module for missions longer than 21 days. The development process has been a long time in the making, and had more than its share of bumps along the way.

Orion-at-KSC_Ken-Kremer1As Mark Geyer, Orion Program manager, explained:

Nothing about building the first of a brand new space transportation system is easy. But the crew module is undoubtedly the most complex component that will fly in December. The pressure vessel, the heat shield, parachute system, avionics — piecing all of that together into a working spacecraft is an accomplishment. Seeing it fly in three months is going to be amazing.

In addition to going to the Moon and Mars, the Orion spacecraft will carry astronauts on voyages venturing father into deep space than ever before. This will include going to the Asteroid Belt, to Europa (to see if there’s any signs of life there), and even beyond – most likely to Enceladus, Titan, the larger moons of Uranus, and all the other wondrous places in the Solar System.

oriontestflightThe two-orbit, four and a half hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 5,800 km (3,600 miles), about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years. It will be an historic occasion, and constitute an important step in what is sure to be known as the Second Space Age.

Dead in Space: Government Shutdown, NASA and Mars

marsAs the government shutdown goes into its second week, there is growing concern over how it is affecting crucial programs and services. And its certainly no secret that a number of federally-funded organizations are worried about how it will affect their long term goals. One such organization is NASA, who has seen much of its operations frozen while the US government attempts to work out its differences.

In addition to 97% of NASA’s 18,000 employees being off the job, its social media accounts and website going dark, and its television channel being shut down, activities ranging from commercial crew payouts, conferences, and awards and scholarship approvals are all being delayed as well. Luckily, certain exemptions are being made when it comes to crucial work on Mars.

NASA_mavenThese include the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter. Following two days of complete work stoppage, technicians working on the orbiter were granted an exemption and permitted to continue prepping it for launch. And not a moment too soon, seeing as how a continued shutdown would have caused the orbiter to miss its crucial launch window.

Designed to survey the Martian atmosphere while orbiting the planet, NASA hopes that MAVEN will provide some clues as to what became of the planet’s onetime atmosphere. MAVEN was been scheduled to blast off for the Red Planet on Nov.18 atop an Atlas V rocket from the Florida Space Coast until those plans were derailed by the start of the government shutdown that began at midnight, Oct. 1.

But as Prof. Bruce Jakosky, MAVEN’s chief scientist, stated in an interview just two days later:

We have already restarted spacecraft processing at the Kennedy Space Center (KSC) today. [Today, we] determined that MAVEN meets the requirements allowing an emergency exception relative to the Anti-Deficiency Act.

Curiosity-roverAnother merciful exception to the shutdown has been the Curiosity Rover. Since contract workers at NASA’s Jet Propulsion Laboratory (JPL) oversee the rover’s mission, the Curiosity team is not subject to the same furloughs as other NASA employees. At JPL, the technicians and workers at the lab are employed by the California Institute of Technology, and are therefore able to keep the mission going.

However, the management at JPL and Cal Tech will continue to assess the situation on a weekly basis, and it’s possible the team may not remain completely intact in the event of a prolonged shutdown. This would be particularly detrimental for Curiosity since the Mars rover requires daily maintenance by scientists, engineers and programmers and cannot run on autopilot.

curiosity_sol-177-1As Veronica McGregor, a media relations manager at JPL, said in a recent interview:

Right now, things continue on as normal. Curiosity is one where they literally look at the data each day, sit down, create a plan, decide what science instrument is going to be used tomorrow, they write software for it and upload it. [It’s] is kind of a unique mission in that way.

Other programs running out JPL will also continue. These include the Opportunity and Odyssey rovers, the Mars Reconnaissance Orbiter, the HiRISE camera, Dawn, Juno, and Spitzer space probes, and the Voyager satellites, APL, MESSENGER, and New Horizons.  In addition, operations aboard the International Space Station will continue, but with the bare minimum of ground crew support.

cassini_spaceprobeRobotic missions that are already in operation – such as the Cassini spacecraft circling Saturn, or the Lunar Atmosphere and Dust Environment Explorer (LADEE) winging its way to the moon – will have small crews making sure that they are functioning properly. However, no scientific analysis will be conducted during the shutdown period.

As the shutdown continues, updates on which programs are still in operation, which ones will need to be discontinued, and how they will be affected will continue to be made available. One can only hope the politically-inspired deadlock will not become a prolonged affair. It’s not just current programs that are being affected after all.

Consider the proposed 2030 manned mission to Mars, or the plans to tow an asteroid closer to Earth. I can’t imagine how awful it would be if they were delayed or mothballed due to budget constraints. Politics… bah!
