One of the most efficient ways to travel between planets would be nuclear powered spacecraft.  However, treaties banning the introduction of nuclear weapons into space have always been seen as an impediment to such spacecraft.  However, NASA seems to be re-examining the issue.

SpaceX Crew Dragon capsule made a safe return today.  Later this summer we should get the first US launched manned mission to space in 8 years. Our long national nightmare is almost over. (post in memory of Mike Nofsinger)

The US has manned spaceflight capabilities again (almost)

It is nothing short of a national disgrace that for a number of years, the US has been reduced to paying the Russians for rides into space.  That this was allowed to happy is something that NASA should forever be ashamed of.  However, we are now close to the US having its own manned spaceflight capability restored, thanks to private industry.  SpaceX has flown an (unmanned) manned crew capsule to the ISS. Later this year, it should fly with a full crew.  Thank God. (post in memory of Mike Nofsiniger)

The Opportunity rover has finally been declared dead.  It was supposed to work for 3 months and ended up lasting 15 years.  That is a real tribute to the engineers at NASA.  While IMHO, we need a moon base, the real target should be men on Mars.  Opportunity got us closer to that goal.  Rest well little rover.

Looks like the USA will be back in the manned crewed spaceflight business by next year. (Thank God!)  This was way too long in coming.

And, NASA just landed another probe on Mars.  Hopefully we will learn a lot and get men on Mars soon.  (Post in memory of Mike Nofsinger)
