Scale solar system presentation slide, version 2

Emily Lakdawalla • October 31, 2011

Last month I posted a preliminary version of a slide I was working on for use in my public presentations, a slide that contains everything in the solar system bigger than 400 kilometers across, and invited comment. I've listened to all of your comments and corrections and come up with a second version.

NPP Earth observatory launched successfully, and I was there!

Emily Lakdawalla • October 28, 2011

Well, that was awesome. The NPP Earth observation satellite launched successfully an hour or so ago, and I was with a chilled but thrilled crowd of a few hundred people to watch it at Vandenberg Air Force Base.

What's up in the solar system in November 2011

Emily Lakdawalla • October 25, 2011

For a few weeks over November and December, a rare launch window to Mars opens, and then slams shut agin. Mars launch windows only happen once each 26 months, so if you miss the window, you have to wait more than two years for the next one.

Emily Lakdawalla • October 25, 2011

The Mars Climate Sounder team has recently confirmed a prediction of a weather phenomenon on Mars that we haven't been able to observe before.

Jim Shirley • October 25, 2011

Science from Vesta at the Geological Society of America meeting

Emily Lakdawalla • October 24, 2011

I'm nearly two weeks late getting to this news but better late than never, right? There was a press briefing from the Dawn mission at the Geological Society of America (GSA) meeting on October 12.

NPP's launching next week, and I'll be there to see it! (Hopefully.)

Emily Lakdawalla • October 21, 2011

I'm (hopefully) headed to the launch of a Delta II (the last currently scheduled Delta II!) at Vandenberg Air Force Base, as one of only 20 people selected to participate out of more than 600 who registered.

Emily Lakdawalla • October 20, 2011

Cassini has completed two very close flybys of Enceladus in less than three weeks, one of them just this morning, and the images from that encounter have already arrived on Earth.

Emily Lakdawalla • October 19, 2011

Programming note: tonight, public television stations will be airing a new, two-hour NOVA documentary, "Finding Life Beyond Earth."

A new trick for IKAROS: Spinning the other way

Emily Lakdawalla • October 19, 2011

JAXA's solar sail demonstration craft IKAROS is still puttering along, 17 months after it launched, and its controllers back on Earth keep coming up with new things to try with it. I'm pretty amazed by the most recent trick: reversing its spin direction. This may not sound like a big deal, but it is, especially for IKAROS.

Book Reviews: Two books that deliver knowledge in little chunks

Emily Lakdawalla • October 18, 2011

I consider October and November to be book review season. We're well out of the mental coasting of summer and have gotten into the groove of school and work in fall, and are in the relative quiet before the insanity of the season that stretches from Thanksgiving to the New Year, when much of the Western world will be scrambling to shop for presents for friends and family.

Phobos-Grunt unpacked! With Yinghuo-1 and LIFE!

Emily Lakdawalla • October 18, 2011

I know I just posted about Phobos-Grunt on Friday, but there are lots of new pictures from Baikonur Cosmodrome (Russia's main launch facility in Kazakhstan) showing Phobos-Grunt being removed from its shipping crate and tipped upright in preparation for its launch in early November.

Heads up! ROSAT is coming down this week

Emily Lakdawalla • October 17, 2011

It should give you a feeling of déjà vu: a defunct satellite's orbit is decaying, and because that orbit is circular it's going to be impossible to predict where and when along its ground track it's going to happen.

Earth observing satellites record large Arctic ozone loss

Jason Davis • October 14, 2011

Data from Earth observing satellites Aura and CALIPSO have shown record losses of seasonal ozone in the Arctic.

While the U.S. Stalls, Europe Moves On to Mars

Charlene Anderson • October 14, 2011

The European Space Agency (ESA) seems to have gotten tired of waiting for NASA to commit to its share of the joint 2016/2018 Mars missions that were planned to lay the groundwork for an eventual delivery of samples of Mars to Earth.
