The Space Launch System will be NASA's first exploration-class vehicle since the Saturn V took American astronauts to the moon over 40 years ago. With its superior lift capability, the SLS will allow us to explore cis-lunar space, near-Earth asteroids, Mars and its moons and beyond.

why don't we use this for long-term space travel :-) ?? anybody wants to have a closer look into this?

did not know about this heroic! experiment to wear the same underwear for two months!

good sign??

I wonder how this will turn out.

boomerang at ISS ...

bon appetit ....

Regarding our discussion on resource self-sufficiency of a Mars colony. Would it ever be possible (from a resource perspective that is..) A NASA report on availability of resources. A self-sufficiency trade study described in Boston (1996) identifies the mission duration at which the development of local life support resources becomes advantageous. Within 30 days, without recycling, or with the equivalent leakage, it becomes advantageous to derive oxygen from local resources. The time constants for water and food are about 6 months and 3 years, respectively.

I guess it depends on the number of astronauts that have to be supporte ... 3 years for food looks like a lot

Our friends from NASA have come out with a plan to the human exploration of Venus in the time that everyone is speaking about Mars.

Love the concept acronym, which pretty much says it all... Not sure which astronaut would fancy floating around in an atmosphere where clouds are made of sulphuric acid. Besides I don't see the point of a manned mission if one can't reach the surface.. tele-operation would be easy and so much cheaper.

In Interstellar, the science-fiction film out this week, Matthew McConaughey stars as an astronaut contending with a supermassive black hole called Gargantua. The film's special effects have been hailed as the most realistic depiction ever made of this type of cosmic object. But astrophysicists have now gone one better - this is a really cool visualisation done by researchers in Cornell.

Wow, impressive! Simulating eXtreme Spacetimes (SXS) software, very quick merging process though 17ms.. Observable?

Mind-blowing!

Loss of connectivity in the multisensory integration cortical areas after short term microgravity experience, which could explain astronauts decrease of performance in sensorimotor tasks and spatial working memory. However, the effect should wear off after a few days in microgravity and after adaptation to incongruent vestibular information. ISS experiment needed...
