When NASA People Say Inaccurate Things NASA Doesn't Care

Keith's note: Yesterday I sent the following email to NASA JPL employee Ron Baalke yesterday about two inaccurate tweets he has posted (and retweeted) regarding the Challenger accident. I cc:ed JPL and NASA HQ PAO. The tweets are still out there misinforming people. No one at NASA seems to care that a NASA employee is perpetuating misleading information. Yes, its a "private" Twitter account - one that goes out of its way to identify the owner as a JPL employee. Yet when other people circulate inaccurate information like this about NASA events NASA PAO gets all upset. Go figure.

"I see that your twitter account just retweeted these tweets. They are factually incorrect on several levels. 1. Space Shuttle Challenger did not "explode". Challenger was torn apart by extreme aerodynamic forces as a result of an explosion in the External Tank. 2. The crew of Space Shuttle Challenger were killed by the breakup of the vehicle and/or the impact of the crew compartment with the ocean at high speed - not by any "explosion". These are matters of established fact. Please correct your tweets."

NASA has a Moon landing plan—sort of

The Lunar X


The striking X in this lunarscape is easily visible in binoculars or a small telescope, but not too many have seen it. The catch is, this lunar X is fleeting and only apparent in the hours before the Moon's first quarter phase. Along the shadow line between lunar day and night, the X illusion is produced by a configuration of craters seen here toward the left, Blanchinus, La Caille and Purbach. Near the Moon's first quarter phase, an astronaut standing close to the craters' position would see the slowly rising Sun very near the horizon. Temporarily, crater walls would be in sunlight while crater floors would still be in darkness. Seen from planet Earth, contrasting sections of bright walls against the dark floors by chance look remarkably like an X. This sharp image of the Lunar X was captured on February 22nd. For extra credit, sweep your gaze along the lunar terminator and you can also spot the Lunar V. via NASA http://ift.tt/2HSh71Q
