Do you want to go to Mars?

Well here’s your chance to get connected for a double barreled dose of Red Planet adventure courtesy of MAVEN – NASA’s next ‘Mission to Mars’ which is due to liftoff this November from the Florida Space Coast.

For a limited time only, NASA is offering the general public two cool ways to get involved and ‘Go to Mars’ aboard a DVD flying on the solar winged MAVEN (Mars Atmosphere and Volatile Evolution) orbiter.

You can send your name and a short poetic message to Mars via the ‘Going to Mars’ campaign being managed by the University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics (CU/LASP).

“Anybody on planet Earth is welcome to participate!” says NASA.

“The Going to Mars campaign offers people worldwide a way to make a personal connection to space, space exploration, and science in general, and share in our excitement about the MAVEN mission,” said Stephanie Renfrow, lead for the MAVEN Education and Public Outreach program at CU/LASP.

Signing up to send your name is easy. Simply click on the MAVEN mission website – here.

Everyone who submits their name will be included on a DVD that will be attached to the winged orbiter. And you can print out a beautiful certificate of participation emblazoned with your name!

Over 1 million folks signed up to send their names to Mars with NASA’s Curiosity rover. So they are all riding along as Curiosity continues making ground breaking science discoveries and already found habitats that could support potential Martian microbes.

Writing the haiku poem will require thought, inspiration and creativity and involves a public contest – because only 3 poems will be selected and sent to Mars. The public will vote for the three winning entries.

Haiku’s are three line poems. The rules state that “the first and last lines must have exactly five syllables each and the middle line must have exactly seven syllables. All messages must be original and not plagiarized in any way.”

The complete contest rules are found at the mission website – here:

This is a simple way for kids and adults alike to participate in humanity’s exploration of the Red Planet. And it’s also a great STEM activity for educators and school kids of all ages before this year’s school season comes to a close.

“This new campaign is a great opportunity to reach the next generation of explorers and excite them about science, technology, engineering and math,” said Bruce Jakosky, MAVEN principal investigator from CU/LASP. “I look forward to sharing our science with the worldwide community as MAVEN begins to piece together what happened to the Red Planet’s atmosphere.”

MAVEN is slated to blast off atop an Atlas V rocket from Cape Canaveral Florida on Nov. 18, 2013. It will join NASA’s armada of four robotic spacecraft when it arrives at Mars during 2014.

MAVEN is the first spacecraft devoted to exploring and understanding the Martian upper atmosphere. The spacecraft will investigate how the loss of Mars’ atmosphere to space determined the history of water on the surface.

But don’t dawdle- the deadline for submissions is July 1.

So, sign up to ‘Go to Mars’ – and do it NOW!

Juice up your inner poet and post your ‘Haiku’ here – if you dare

More Evidence That Mars Lost Its Atmosphere

Although today Mars’ atmosphere is sparse and thin — barely 1% the density of Earth’s at sea level — scientists don’t believe that was always the case. The Red Planet likely had a much denser atmosphere similar to ours, long, long ago. So… what happened to it?

NASA’s Curiosity rover has now found strong evidence that Mars lost much of its atmosphere to space — just as many scientists have suspected. The findings were announced today at the EGU 2013 General Assembly in Vienna.

Curiosity’s microwave oven-sized Sample Analysis at Mars (SAM) instrument analyzed an atmosphere sample last week using a process that concentrates selected gases. The results provided the most precise measurements ever made of isotopes of argon in the Martian atmosphere.

Isotopes are variants of the same element with different atomic weights.

“We found arguably the clearest and most robust signature of atmospheric loss on Mars,” said Sushil Atreya, a SAM co-investigator at the University of Michigan.

SAM found that the Martian atmosphere has about four times as much of a lighter stable isotope (argon-36) compared to a heavier one (argon-38). This ratio is much lower than the Solar System’s original ratio, as estimated from measurements of the Sun and Jupiter.

This also removes previous uncertainty about the ratio in the Martian atmosphere in measurements from NASA’s Viking project in 1976, as well as from small volumes of argon extracted from Martian meteorites retrieved here on Earth.

These findings point to a process that favored loss of the lighter isotope over the heavier one, likely through gas escaping from the top of the atmosphere. This appears to be in line with a previously-suggested process called sputtering, by which atoms are knocked out of the upper atmosphere by energetic particles in the solar wind.

Lacking a strong magnetic field, Mars’ atmosphere would have been extremely susceptible to atmospheric erosion by sputtering billions of years ago, when the solar wind was an estimated 300 times the density it is today.

These findings by Curiosity and SAM will undoubtedly support those made by NASA’s upcoming MAVEN mission, which will determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space. Scheduled to launch in November, MAVEN will be the first mission devoted to understanding Mars’ upper atmosphere.

MAVEN’s Magnetometer Will Look Back in Time

The next mission to the Red Planet, the Mars Atmosphere and Volatile Evolution (MAVEN) will be the first spacecraft ever to make direct measurements of the Martian atmosphere. MAVEN will carry eight science instruments, including a magnetometer that will investigate what remains of Mars’ magnetic “shield,” and will, in essence, help to look back in time at what may have happened to a planet once thought to have an abundance of liquid water but is now a frozen desert. The magnetometer will play a key role in studying the planet’s atmosphere and interactions with solar wind, helping answer the question of why Mars lost much of its atmosphere.

“The magnetometer helps us see where the atmosphere is protected by mini-magnetospheres and where it’s open to solar wind,” said Jack Connerney, a co-investigator for the mission. “We can study the solar wind impact and how efficient it is at stripping the atmosphere.”


By measuring sections of the planet’s magnetic field, the magnetometer could help scientists create a bigger picture of the planet’s overall atmosphere.

MAVEN is the first mission to Mars specifically designed to help scientists understand the past – and also the ongoing — escape of CO2 and other gases into space. MAVEN will orbit Mars for at least one Earth-year, about a half of a Martian year. MAVEN will provide information on how and how fast atmospheric gases are being lost to space today, and infer from those detailed studies what happened in the past.

Studying how the Martian atmosphere was lost to space can reveal clues about the impact that change had on the Martian climate, geologic, and geochemical conditions over time, all of which are important in understanding whether Mars had an environment able to support life.

MAVEN is scheduled to launch in 2013, with a launch window from Nov. 18 to Dec 7, 2013. Mars Orbit Insertion will be in mid-September2014.

So, You Want to Build a Satellite?

A light-hearted look from the upcoming MAVEN (Mars Atmosphere and Volatile Evolution) mission to Mars of what it takes to create a satellite mission for NASA — even before you ever start building it. And the MAVEN folks should know — NASA has just given the mission a green light to continue the development of the mission, which will investigate the mystery of how Mars lost much of its atmosphere. The approval to proceed followed a review at NASA Headquarters of the detailed plans, instrument suite, budget, and risk factor analysis for the spacecraft. You can see how that all works, (presumably problem free) in this witty little video.
