Down to Earth

This week is the time every year for somber reflection at NASA, as it sees the anniversaries of all three of NASA’s spaceflight fatalities: Apollo 1 on January 27, Challenger on January 28, and Columbia on February 1. This coming  February marks 10 years since the space shuttle Columbia was lost on mission STS-107. It’s not fun to watch, but I do re-watch this video* from time to time to remind myself that things can and will go wrong in this dangerous business.

*It amazes me the number of cameras that were on hand in Mission Control for Space Shuttle re-entry. In routine ISS operations, I’ve never had to deal with a camera in my face the way these ascent/entry flight controllers did.

The makers of a small budget documentary about Ilan Ramon, the first Israeli astronaut, lost on Columbia, will air on PBS this Thursday night. I saw an early cut of the film a few years ago and it is well worth watching – I suggest you tune in! Here is their trailer.

In Orbit

Well, he didn’t quite make it to orbit, but an Iranian monkey did fly to space, according to reports out of that country.

The United States government says the monkey’s flight is (officially) unconfirmed.

The Robotic Refueling Mission aboard the ISS wrapped up successfully. The several weeks of operations completed with a successfully simulated refueling, using ethanol, early Monday morning.

And if you need to relax, here’s what it’s like to orbit the Earth from a couple hundred miles up.

Or if you prefer, here is a nice event from last week in which two NASA astronauts on ISS answered student questions live on TV. I enjoyed it live from the Flight Control Room!

Around the Solar System

This month is the 9th anniversary of the Mars Exploration Rovers landing on Mars and the start of Opportunity’s tenth year exploring that planet. Curiosity has a long way to go to match the legacy of Oppy, who landed on January 25, 2004. I can’t wait for her ten year anniversary next year, which I believe she will easily surpass. As Stu, from The Road to Endeavour, points out, Opportunity has spent far more of her life on Mars than she ever did on Earth. She is truly a Martian.

On the other side of Mars from Opportunity, Curiosity has taken her first nighttime pictures! Curiosity can take pictures with white LEDs or ultraviolet light. this can reveal some specific properties of the local geography that are trickier to pinpoint when you have the complex wavelengths of light coming from the sun. In particular, UV light can help Curiosity find fluorescent minerals, which could indicate organics.

Also, Curiosity has discovered lots of evidence of a water-rich past in Gale Crater, including calcium deposits. Curiosity should be doing her first rock drilling very soon!

Because it’s Cool

Stunning exposure of the ISS and the night sky.

NASA TV has been playing this video… awesome.
