7:56 PM | The Many Resurrections of the Hubble Space Telescope
If you are old enough to remember news stories from 1990 (or if you are a devoted student of astronomy), you'll recall that the Hubble Space Telescope was not always regarded as the technological triumph that NASA is loudly celebrating today, on its 25th anniversary. The orbiting observatory debuted as a king-size disaster: the telescope that couldn't see straight, built with a mirror that was ground perfectly...but perfectly incorrect. The story of how the error was discovered and ultima

8:06 AM | With This Ring
Before World War II, the Roman wedding ritual only blessed the bride’s ring. The male wedding band’s popularity didn’t take off until the 1950s, a combination of jewelry industry marketing and the growing association of masculine domesticity with national prosperity. Suddenly, men could be identified as single or ‘taken’ at a glance. Folklore has it that […]

11:00 PM | Sols 964-965: Logan’s Run? Or just a short dash…
By Lauren Edgar Although we had planned a drive of up to 48 m towards “Logan’s Run” on Sol 963, the drive ended early after only 17 m due to the detection of a nearby hazard (a large rock).  This was the first time in a while that we were using autonav for driving.  The good news is that the hazard was detected, and the events are understood.  It just means …

“I found I could say things with color and shapes that I couldn’t say any other way — things I had no words for.” -Georgia O’Keeffe We thought — back in the time after Maxwell — that if we understood gravitation and electromagnetism, we’d understand all the forces in the Universe. But once we started to dive…

4:33 PM | Happy Birthday to Our Fellow 'Great Observatory'
If you are at all interested in astronomy, chances are you’ve heard that the Hubble Space Telescope is celebrating its 25th anniversary this week. What some people may not know is that Hubble is one of four siblings, so to speak. Back in the 1980s, NASA commissioned the"Great Observatories," each designed and built to study different wavelengths of light. The four Great Observatories, in order of their launches that took place between 1990 and 2003, are Hubble, the Compton Gamma Ray […]
