MAVEN launches to Mars

18 Nov

Watch the launch video:

MAVEN (which stands for Mars Atmosphere and Volatile EvolutioN) launched on schedule at 1:28pm EST (18:28 UTC) on Monday, November 18, 2013 from the Cape Canaveral Air Force Station Space Launch Complex 41 in Florida atop an Atlas V rocket, supplied by United Launch Alliance. With the on-schedule launch at the beginning on the launch window, MAVEN’s 10-month journey to Mars will see it arrive in orbit of the red planet on September 22, 2014.

Once in orbit around Mars, MAVEN will help us to understand what happened on Mars that caused it to transform from a warm, wet world into the dry desert we know today. In other words, where did the atmosphere and water go, and how did it happen?

In order to achieve its goals, MAVEN has eight instruments bundled into three scientific suites. These instruments include: the Neutral Gas and Ion Mass Spectrometer, Imaging Ultraviolet Spectrograph, Magnetometer, Solar Wind Electron Analyzer, SupraThermal And Thermal Ion Composition, Langmuir Probe and Waves antenna, Solar Energetic Particles, and the Solar Wind Ion Analyzer.

With its “gull wing” solar arrays fully extended, MAVEN’s wingspan comes in at 11.3 meters (37 feet). The dry mass is 903 kg (1,991 lbs), with an additional 1,645 kg (3,627 lbs) of fuel. The solar arrays provide a maximum power output of 1135 watts at Mars aphelion.

The month of November is also a historically significant month for space exploration – and in particular the exploration of Mars. In November 1971, Mariner 9 successfully entered orbit around Mars and became the first human made object to orbit another world – just ahead of the twin Soviet probes Mars 2 and Mars 3.

Taking spaceflight for granted

Anyone who knows me in person or online knows that when there is a rocket launch, I get excited. I watch the launches. I tweet along. I post and share videos of them. I even flew to Florida once with a good friend to take in a Shuttle launch (Orbiter Atlantis on STS-132 in May 2010).

I watched with great interest last week when an Antares rocket blasted off to the International Space Station with the new Cygnus vessel. I kept a very close eye yesterday as a Soyuz soared into space with three new astronauts, also bound for humanity’s most distant outpost.

But following such things so closely puts me in a small – perhaps a very small – minority.

Is this because the majority of people don’t care about spaceflight and exploration?

I don’t think so.

Looking at recent missions that got significant attention, we don’t have to go too far back: Canadian astronaut Chris Hadfield garnered significant attention from fans, on social media, and even in the mainstream media during his stay on the International Space Station.

Ditto NASA’s Mars Science Laboratory, aka Curiosity, when it landed on Mars in August 2012.

People all over the world are passionate about spaceflight, exploration, and discovery. People are interested when special things happen.

And that last sentence is the crux of why people don’t pay attention to spaceflight.

Spaceflight isn’t seen as “special” – it’s considered routine. And routine things don’t make the news or become the topics of water cooler conversations in your office.

Now for the scientists, engineers, mission planners, astronauts, administrators, and everyone else involved in putting spaceflight together this is a good thing. The fact that the public sees spaceflight as routine is a credit to just how good they are at their jobs. They’re so good, executing consistently with such a high degree of precision, that they are able to make exceptionally difficult tasks appear easy.

But there is a downside to this excellence: public apathy to what are, in reality, incredible feats.

Every time a rocket launches there are millions of things that could go wrong. Any one of those things could jeopardize the mission – and perhaps endanger lives.

But the public has come to (correctly) expect that nothing will go wrong. They expect to hear in passing that there was another successful launch and humanity’s exploration of space continues. Next story.

The public is taking spaceflight for granted.

But this is not a wise state of mind. Spaceflight is incredibly challenging to achieve – and when success is taken for granted people become careless. Limits are pushed. Things go wrong.

People close to missions know this. They work hard to stay focused to ensure everything works perfectly, every time.

I submit, humbly, that the public should remember this as well.

There is nothing routine about spaceflight, and a couple minutes on the evening news or a few minutes of discussion around the water cooler would be a valuable nod to all the people who have worked so very hard to make it look so very easy.
