The journey to Mars crosses three thresholds, each with increasing challenges as humans move farther from Earth. We’re managing these challenges by developing and demonstrating capabilities in incremental steps:
Earth Reliant
Earth Reliant exploration is focused on research aboard the International Space Station. From this world-class microgravity laboratory, we are testing technologies and advancing human health and performance research that will enable deep space, long duration missions.
On the space station, we are advancing human health and behavioral research for Mars-class missions. We are pushing the state-of-the-art life support systems, printing 3-D parts and analyzing material handling techniques.
Proving Ground
In the Proving Ground, we will learn to conduct complex operations in a deep space environment that allows crews to return to Earth in a matter of days. Primarily operating in cislunar space (the volume of space around the moon). We will advance and validate the capabilities required for humans to live and work at distances much farther away from our home planet…such as at Mars.
Earth Independent
Earth Independent activities build on what we learn on the space station and in deep space to enable human missions to the Mars vicinity, possibly to low-Mars orbit or one of the Martian moons, and eventually the Martian surface. Future Mars missions will represent a collaborative effort between us and our partners.
Did you know….that through our robotic missions, we have already been on and around Mars for 40 years! Taking nearly every opportunity to send orbiters, landers and rovers with increasingly complex experiments and sensing systems. These orbiters and rovers have returned vital data about the Martian environment, helping us understand what challenges we may face and resources we may encounter.
Through the Asteroid Redirect Mission (ARM), we will demonstrate an advanced solar electric propulsion capability that will be a critical component of our journey to Mars. ARM will also provide an unprecedented opportunity for us to validate new spacewalk and sample handling techniques as astronauts investigate several tons of an asteroid boulder.
Living and working in space require accepting risks – and the journey to Mars is worth the risks. A new and powerful space transportation system is key to the journey, but we will also need to learn new ways of operating in space.
We Need You!
In the future, Mars will need all kinds of explorers, farmers, surveyors, teachers…but most of all YOU! As we overcome the challenges associated with traveling to deep space, we will still need the next generation of explorers to join us on this journey. Come with us on the journey to Mars as we explore with robots and send humans there one day.

HUGE ANNOUNCEMENT!
Elon Musk is set to announce his plans for Mars colonization in an hour, at 2:30 Eastern Time.
Please watch it because this could be history in the making.
In addition to the Mercury transit of the sun today, there are a few other things you should know about our solar system this week:
1. Mars, Ready for its Close-Up
Mars will soon be closer to Earth than it has been for 11 years, presenting a great opportunity for backyard sky watchers.
2. Fire and Ice
Our spacecraft have an even closer view of Mars, and that fact regularly leads to some intriguing discoveries. The latest: volcanoes may have erupted beneath an ice sheet there billions of years ago. The above image is a mineral map of part of the Martian surface.
3. Icy Hydra
Meanwhile, our New Horizons spacecraft has sent home the first compositional data about Pluto’s four small moons. The new data show the surface of Hydra is dominated by nearly pristine water ice–confirming hints that scientists picked up in images showing Hydra’s highly reflective surface.
4. Ceres, Ever Sharper
The mission director for our Dawn mission writes, “Ceres, which only last year was hardly more than a fuzzy blob against the stars, is now a richly detailed world, and our portrait grows more elaborate every day.”
5. Join us at Jupiter
Our Juno mission arrives at the giant planet on Jul. 4. Meanwhile, all amateur astronomers are invited to take part in a worldwide effort to identify potential observations for the spacecraft to make once it’s in orbit. Find out how to join HERE.

SpaceX is scheduled to launch its Dragon spacecraft PACKED with super cool research and technology to the International Space Station June 1 from Kennedy Space Center in Florida. New solar panels, investigations that study neutron stars and even fruit flies are on the cargo list. Let’s take a look at what other bits of science are making their way to the orbiting laboratory 250 miles above the Earth…
New solar panels to test concept for more efficient power source
Solar panels generate power well, but they can be delicate and large when used to power a spacecraft or satellites. This technology demonstration is a solar panel concept that is lighter and stores more compactly for launch than the solar panels currently in use.
Roll-Out Solar Array (ROSA) has solar cells on a flexible blanket and a framework that rolls out like a tape measure and snap into place, and could be used to power future space vehicles.
Investigation to Study Composition of Neutron Stars
Neutron stars, the glowing cinders left behind when massive stars explode as supernovas, contain exotic states of matter that are impossible to replicate in any lab. NICER studies the makeup of these stars, and could provide new insight into their nature and super weird behavior.
Neutron stars emit X-ray radiation, enabling the NICER technology to observe and record information about its structure, dynamics and energetics.
Experiment to Study Effect of New Drug on Bone Loss
When people and animals spend lots of space, they experience bone density loss. In-flight exercise can prevent it from getting worse, but there isn’t a therapy on Earth or in space that can restore bone that is already lost.
The Systemic Therapy of NELL-1 for osteoporosis (Rodent Research-5) investigation tests a new drug that can both rebuild bone and block further bone loss, improving health for crew members.
Research to Understand Cardiovascular Changes
Exposure to reduced gravity environments can result in cardiovascular changes such as fluid shifts, changes in total blood volume, heartbeat and heart rhythm irregularities, and diminished aerobic capacity.
The Fruit Fly Lab-02 study will use the fruit fly (Drosophila melanogaster) to better understand the underlying mechanisms responsible for the adverse effects of prolonged exposure to microgravity on the heart. Fruit flies are effective model organisms, and we don’t mean on the fashion runway. Want to see how 1,000 bottles of fruit flies were prepared to go to space? Check THIS out.
Space Life-Support Investigation
Currently, the life-support systems aboard the space station require special equipment to separate liquids and gases. This technology utilizes rotating and moving parts that, if broken or otherwise compromised, could cause contamination aboard the station.
The Capillary Structures investigation studies a new method of water recycling and carbon dioxide removal using structures designed in specific shapes to manage fluid and gas mixtures.
Earth-Observation Tools
Orbiting approximately 250 miles above the Earth’s surface, the space station provides pretty amazing views of the Earth. The Multiple User System for Earth Sensing (MUSES) facility hosts Earth-viewing instruments such as high-resolution digital cameras, hyperspectral imagers, and provides precision pointing and other accommodations.
This investigation can produce data that could be used for maritime domain awareness, agricultural awareness, food security, disaster response, air quality, oil and gas exploration and fire detection.

in 20-70 million years, Mars’ moon Phobos will get close enough to the surface of the planet that it will be ripped apart by the tidal forces. The resulting debris will most likely give Mars a planetary ring.
POTENTIAL HABITATS FOR EARLY LIFE ON MARS
Recently discovered evidence of carbonates beneath the surface of Mars points to a warmer and wetter environment in that planet’s past. The presence of liquid water could have fostered the emergence of life.
A new study by James Wray at the Georgia Institute of Technology and Janice Bishop of the SETI Institute, as well as other collaborators, has found evidence for widespread buried deposits of iron- and calcium-rich Martian carbonates, which suggests a wetter past for the Red Planet.
“Identification of these ancient carbonates and clays on Mars represents a window into history when the climate on Mars was very different from the cold and dry desert of today,” notes Bishop.
The fate of water on Mars has been energetically debated by scientists because the planet is currently dry and cold, in contrast to the widespread fluvial features that etch much of its surface. Scientists believe that if water did once flow on the surface of Mars, the planet’s bedrock should be full of carbonates and clays, which would be evidence that Mars once hosted habitable environments with liquid water. Researchers have struggled to find physical evidence for carbonate-rich bedrock, which may have formed when carbon dioxide in the planet’s early atmosphere was trapped in ancient surface waters. They have focused their search on Mars’ Huygens basin.
This feature is an ideal site to investigate carbonates because multiple impact craters and troughs have exposed ancient, subsurface materials where carbonates can be detected across a broad region. And according to study led James Wray, “outcrops in the 450-km wide Huygens basin contain both clay minerals and iron- or calcium-rich carbonate-bearing rocks.”
The study has highlighted evidence of carbonate-bearing rocks in multiple sites across Mars, including Lucaya crater, where carbonates and clays 3.8 billion years old were buried by as much as 5 km of lava and caprock.
The researchers, supported by the SETI Institute’s NASA Astrobiology Institute (NAI) team, identified carbonates on the planet using data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), which is on the Mars Reconnaissance Orbiter. This instrument collects the spectral fingerprints of carbonates and other minerals through vibrational transitions of the molecules in their crystal structure that produce infrared emission. The team paired CRISM data with images from the High Resolution Imaging Science Experiment (HiRISE) and Context Camera (CTX) on the orbiter, as well as the Mars Orbiter Laser Altimeter (MOLA) on the Mars Global Surveyor, to gain insights into the geologic features associated with carbonate-bearing rocks.
The extent of the global distribution of martian carbonates is not yet fully resolved and the early climate on the Red Planet is still subject of debate. However, this study is a forward step in understanding the potential habitability of ancient Mars.
