All the Wild **** We're Going to Do in Space and Physics in 2018 (forum censors the original title)
Featuring all the interplanetary probes and various missions and milestones closer to Earth, the Event Horizon Telescope, Gaia, and a couple of things not directly related to space or...
i'v googled the subject and it seems like a serious problem, e.g. the dust accumulating on the solar panels, there has even been a term coined 'cleaning event' for Mars winds, as if this is a matter of luck to get the solar panels cleaned. A small carbon-dioxide vent on the tip of the rover...
According to recent research news, swedish PhD scholars have said that solar wind induces currents in the ionosphere of mars. This causes an induced magnetoshere which in turn protects the atmosphere from the same wind. This is quite difficult to believe. It is well known that Mars does not...
we know that the moon is far away
the distance between us and the moon can fit all the other 7 planets and some small dwarf planets
but how ?
it would take us 3 days to reach the moon and the spacecraft were traveling in at least 240,000 miles
it should take us more than a year to reach the...
NASA announced in 2015 that they found some evidence for the existence of liquid water on Mars today - at least temporarily and underground.
A new study comes to a different conclusion and proposes sand as origin of the observed material transport downhill.
As interesting as these features...
So long story short, I'm trying to write a scientifically accurate short story/animation thing and it revolves around a mass driver: it's a giant and deep hole on Mars with a magnet on the bottom or sides or something and fires packets of objects to Earth at breathtaking speeds (4.66 million...
Hi! I'm doing a research project titled "Is it possible to colonise Mars?" I'm currently researching how to raise the temperature and pressure - and I've discovered to do this that re-directing asteroids towards Mars containing Ammonia would be vital.
However, where do these asteroids that...

Some points to note are
* The polar region contains enough frozen water to cover the whole planet in a liquid layer approximately 11 meters (36 feet) deep.
* The radar sees through icy layers to the lower...
Elon Musk presents his updated plan for the colonization of Mars.at the International Astronautical Congress in Australia. First sending two pilotless supply ships to Mars by 2022 using a new rocket, the BFR,.
Hi,
Do you think there is any feasibility at all to terraform Mars be crashing Europa into it? Of course, you have the near impossible task of knocking Europa out of Jupiter's orbit and guiding into Mars without ruining its orbit...but if it worked maybe this would give Mars the extra mass...
Specifically, how does the moon's mass and size determine the distance and orientation of Mars in relation to Earth. If the moon was drilled and mined of half its mass, would that have any significant effect in the solar system?
A group of astronauts may spend a year in orbit around the moon in the late 2020s as part of NASA's plan to send humans to Mars in the 2030s, agency officials said today (May 9).
Greg Williams, NASA's deputy associate administrator for policy and plans in the agency's Human Exploration and...
I want to ask for your thoughts about Mars exploration in the current time we live in. Why do you personally think we should or should not strive to put money, time, and effort to send an astronaut to mars?
My thoughts about this topic are how we should put forth our current developments and...
"The search for water, or even signs of life, on the planet Mars has been ongoing for some time. But with today’s announcement by CERN and NASA scientists, the exploration of the red planet has revealed a major new discovery. New images of the surface of Mars taken by NASA’s Mars Reconnaissance...
Homework Statement
To what radius do you need to compress Mars in order to turn it into a black hole?
Homework Equations
None given, but I am mildly familiar with Schwarzschild and his equation. I know that if we double the object's mass, multiply by the universal gravitational constant, and...
NASA scientists have proposed a magnetic shield that would sit at the L1 Lagrange Point beyond the planet, creating an artificial magnetosphere that would deflect solar winds and incoming radiation... Let's discuss thoughts and implications, engineering problems, etc. in such a formidable task...
If we took some of Earth's hardiest extremophile microorganisms and placed them on Mars, what one factor on Mars would be most difficult for them to cope with?
too cold, low oxygen, low atmospheric pressure, radiation, lack of liquid water, toxic soil, lack of organic material, acidity
Please...
Where exactly on Mars is the best spot to set up camp for a colony? I've been reading about the Hellas Basin, which seems favorable regarding asmospheric pressure and ability to host liquid water (0 to 50 degrees F). However, it's located halfway between the Martian equator and the south pole...
In light of the strong desire to begin colonizing Mars in the near future, how easy will it be to remove Mars from the list of planets covered by the planetary protection treaty?
In addition to being intelligent and possessing important skills, are there any specific height and weight requirements for Mars astronauts?
For example, a neighbor on my street would like to become an astronaut. However, he weighs approximately 300 pounds.
Deimos has one advantage that the other two don't - near-zero gravity.
Like Mars, it has a day/night cycle that Humans and plants can adapt to. It almost certainly has water ice. The delta v budget is such that it's actually one of the easier places to mine ice to return to Earth orbit. It has...
Once humans begin arriving on Mars in the next decade or two, how will they keep time and organize their calendar? Will a special Mars date and time system need to be developed or will the colonists (at least initially) stay on pace with the Earth-based system of 24-hour days and 12-month...
I watched the 6-episode series called Mars this week. Elon Musk kept emphasizing that humans must spread out to at least one other planet to ensure human survival in the event of some extinction event on Earth.
Wouldn't colonization of the Moon achieve the same purpose? Seems like that would...
Hey guys, I am doing a project for two of my classes, technical writing and Unifying Concepts in Physics. I am researching the feasibility of terraforming Mars to present for my final presentation. I need to present some quantitative data by putting out a survey, so here are two questions I'd...
Recently I read a book about Mars, and it says that global sandstorm blows from southern hemisphere to northern hemisphere at perihelion. It's because the southern part is more heated at that position and the closer distance to sun gives it a high temperature, thus sublimating large amount CO2...
NASA report.
~10,000 cubic kilometers, more than even the most enthusiastic colony concepts could use in the whole 21st century, and even if we don't take recycling into account at all. The ground has 50-85% water ice, buried under a 1 to 10 meter surface layer of regolith - it should be easy...
I have read a previous forum discussing the possibility of creating a stronger magnetic field on Mars using tidal forces by putting a larger moon in orbit around Mars. My question is how large of an object would it have to be compared to Mars and how distant would its orbit need to be from the...

Return trips to Mars without refueling could be a step closer, thanks to a unique new thruster technology.
I know Mars colonization is a hot topic these days, and there are a lot of threads on this topic, but I would like to discuss specifically the SpaceX Interplanetary Transport System.
There's a video on the subject here.
On a recent thread that I posted here, some people came to the conclusion...
I thought a bit about the prospect of terraforming other worlds starting with the ones closest to us, Mars and Venus.
Personally even though I don't mind the hype over Mars, I prefer thinking of Venus as the main target for terraforming.
it's just a lot more tempting.
for example:
It's surface...
I'm trying to find out if Mars has any Lagrange Points - L1 and L2 specifically. A lengthy trawl through Google's webpages suggest that they may exist, although if so they would be extremely close to Mars, being gravitationally bound by Phobos and Deimos. Is this true?
PS. Should Mars indeed...
I'm going to write a space opera, a part of it involves Mars. I wonder about the plausibility level of my following imaginations.
"She descanded on the space elevator. The landscape outside looked like a mushroom field. There were transparent and red ones. The hats of the former ones were big...
I have been studying astronomy and astrophysics for about 2 years now, though on my own time and by my self. A recent question came into my mind, Can arctic planets exist close to their star? Now, in my understanding of planetary science, in order for a planet to be cool and close to the sun, it...
I have been reading about Mars and planetary rotation and gravity. It seems to me Mars was in Earth's rotation at one time. Most likely it's first period. I want it back. I don't believe it's an impossible task. People exercise drilling and fracking and sending out satalites. How impossible is...

I found this old Wired article interesting. It makes me wonder, with all the cash that is thrown at Mars exploration these days, why an updated version of this has not been attempted? It would seem that analysis of a Martian...
Hi everyone. I'm trying to derive an expression of the velocity of an object in free fall on Mars, and I am having trouble. Here is what I've done so far:
Drag on Mars can be expressed as
$$F_d = \frac{C_d A \rho_M v^2}{2}, $$ where C_d denotes the drag coefficient, A the reference area, and...

The Viking landers on Mars measured a seasonal change in surface pressure of 2.5 mb due
to the variation in the seasonal extent of the ice caps. Ignoring any elevation variations on
the surface of Mars, calculate the difference in the total mass of CO2 in both ice caps...
Idk where i picked this up, but there is one other plausible colony destination for humans: Venus.
After a few trips on the net, I've come to the "Aerostat on Venus" side instead of a colony on mars. I'll mention some of the reasons I've picked up as to why:
1. Tons of CO2, we can use that.
2...
So, I'm building an rc plane for school that has to theoretically be able to fly on Mars. What differences/limitations are there compared to designing a regular remote controlled plane? This is for a terraformation project, so at this point Mars would have an atmospheric pressure of 50kPa.
Hi
I've not seen "The Martian" yet, but I have followed some of the online comments about the supposed radiation levels the film's protagonist would experience whilst stranded on Mars. By "radiation", I assume this to comprise of the solar wind and cosmic rays, both of which, I gather - aside...
So off to Mars we go. But really how are we going to get there? The most expensive part of space travel is overcoming atmosphere. So you could say the biggest obstacle of space travel is Earth travel. It takes virtually no energy to cross space but it takes massive amounts to get into space...

I think 'huge' may be a gross overstatement. I think they're going to announce how recently Mars' atmo was thick and how soon it will be gone, and that's about it.
