Discovery has landed

The Red Planet is about to be spectacular!

 

This month and next, Earth is catching up with Mars in an  encounter that

will culminate in the closest  approach between the two planets in

recorded  history. The next time Mars may come this close is

in 2287. Due to the way Jupiter's gravity tugs on

Mars and perturbs its orbit, astronomers can only be

certain that Mars has not come this close to Earth

in the Last 5,000 years, but it may be as long as

60,000 years before it happens again.

 

The encounter will culminate on August 27th when

Mars comes to within 34,649,589 miles of Earth and

will be (next to the moon) the brightest object in

the night sky. It will attain a magnitude of -2.9

and will appear 25.11 arc seconds wide. At a modest

75-power magnification...

Mars will look as large as the full moon to the naked eye.

 

Mars will be easy to spot. At the

beginning of August it will rise in the east at 10p.m.

and reach its azimuth at about 3 a.m.

 

By the end of August when the two planets are

closest, Mars will rise at nightfall and reach its

highest point in the sky at 12:30a.m. That's pretty

convenient to see something that no human being has

seen in recorded history. So, mark your calendar at

the beginning of August to see Mars grow

progressively brighter and brighter throughout the

month.

Is it just me, or does it seem like we now have a one orbiter fleet?  How long until the next Return to Flight mission?

Atlantis is scheduled to launch on STS-115 the end of September. Discovery goes up no earlier than December 12th.

 

Discovery flew the last two missions, but Atlantis was ready to launch for the emergency rescue missions as needed. Discovery is on standby for STS-115. Endeavor is still in her OMDP (orbiter maintenance down period) as will not return to service until January.

 

Whatever happened to the idea of going back to mainly disposable (and probably safer) spacecraft?

 

I kind of miss the Cold War. Better space race and simpler geopolitical problems.

The new CEV and CaLV (Ares I and V) are in developement. They very much resemble a cross between Saturn and shuttle. The first stage of Ares V is very much like the first stage Saturn V, with SRBs and disposable engines. The Ares I is to be used for crew launch and looks like an Apollo capsule riding on top of a SRB...
