Nitrogen is usually considered the key missing element to terraforming Mars. There might be some in existence somewhere, but yes, Mars would need a lot more nitrogen than it currently has in it's … atmosphere. According to this article, it is very difficult to detect Nitrates via spectroscopy, and they typically would only exist at least 1 meter below the surface. Until we start digging on Mars, we …

Mars, for instance. All we can do is say things about the locations we visited. But that can help us better understand Mars as a whole, particularly when combined with on orbit data. …

You could, but it wouldn't make sense. The most fuel efficient way to enter an areosynchronous (same as geosynchronous, but Mars) would be to do a close pass of Mars to orbit, burning until the …

Earth and Mars really only align every 26 months or so. One particular instant in that is the Hohmann Transfer window, the rest is just close to it, in terms of time, delta-v, etc. If delta-v isn't … an issue, we can launch any time, but it will be faster when Earth and Mars are close to each other, if it is an issue, but we have more than is current, we can launch a bit after the optimal transfer window and arrive there beforehand. …

for simplicity let's use the worst case of equal direction in all direction. Let's even assume all of the energy that hits the ground will be reflected. The lowest orbit around Mars is about 300 km …

let's say 200 m/s, which translates to an actual C3 of 56 km^2/s^s. That is far more energy then is required for a Mars mission, allowing one to select the date to a high degree of precision. I …

There are a couple of popular methods. One is the Darian calendar, which has 24 months of 27-28 sols, with month names based on constellations. More of them are discussed in the Martian Timekeeping ar …

Putting it half-way between Earth and Mars doesn't make as much sense as you think. It's something akin to putting a ship half-way between two other ships. It's a moving target, and doesn't really …

The highest global coverage of Mars belongs to the THEMIS camera, which has a resolution of 100m per pixel. CTX will likely have global coverage as well, it is currently at 75% coverage, as of April … 12, 2012. No doubt this is even higher since then. The highest resolution from orbit at Mars is the HiRISE camera, at 25 cm/pixel. Earth's Oceans, for instance, don't have near the resolution. There …

The fix as show in the movie wouldn't work. To seal off the atmosphere in a more permanent manner, one would need to have something much stronger than Duct tape, or any tape. That wouldn't hold a seal …

The Case for Mars by Robert Zubrin suggests making clay bricks on Mars. Most of the surface of Mars contains materials that would be excellent to produce clay, with such fine grained dust everywhere …

The HiRISE camera on the Mars Reconnaissance Orbiter has 3 color sensors, red (440-850nm), blue-green (400-600nm), and near-infrared (800-1000nm). Why these particular channels? Why not standard visible colors? …

Everywhere on Earth that we find water, we find life. From deep in the crust, to under the Antarctic ice sheets, to the most salty locations on the planet, life seems to follow water. The thought is, …
