Blast from the past: Pioneer 10 and 11 pictures of Jupiter

Here's a few pretty pictures that were recently dusted off by Ted Stryk. Pioneer 10 and 11 passed by Jupiter on December 4, 1973, and December 3, 1974, respectively. Here are three pictures from those two encounters, in versions newly processed by Ted from scanned photographic prints found during a research trip to NASA's Ames Research Center.

How to watch the GRAIL launch on Thursday

The twin spacecraft of the GRAIL lunar gravity mission are set to launch side-by-side on a Delta II rocket on Thursday, September 8. Here's all the places where you can find information about the upcoming launch.

Dawn Journal: Spiraling Down from Survey Orbit

Dawn has completed the first phase of its exploration of Vesta with tremendous success, and the peripatetic adventurer is now in powered flight again, on its way to a new location from which to scrutinize its subject.

Pretty picture: Earth and Moon from JunoCam

It's always awe-inspiring to see our great world as just a tiny spot within vast space. The latest spacecraft to get such a view of Earth and the Moon is the Jupiter-bound Juno.

Everybody says we need a NEO survey telescope

The next thing needed by both the small bodies science community and people interested in human exploration is a space-based telescope capable of surveying (and following up on) near-Earth space for asteroids that, for a variety of reasons, haven't been found yet.

Dawn Journal: In Survey Orbit (belatedly)

Dawn is now beginning intensive observations of the alien world it orbits. The approach phase, which began on May 3 is complete. Today Dawn is in its survey orbit around Vesta.

Holey Hyperion!

Yesterday Cassini passed unusually close by Hyperion, the oddly shaped moon that orbits Saturn just beyond Titan. Among the many cool images captured during this flyby were three that I used to make this neato view of Hyperion's crescent.

Nifty GRAIL animation

A pair of lunar spacecraft is launching in two weeks, and NASA had their preview press briefing this morning. Notable from that briefing was this spiffy video.

Pretty picture: Saturn from very close up

I haven't checked in on Cassini lately. I went to the raw images page and found the frames for this very lovely, very close view of Saturn. It was taken by Cassini two days ago, as it was approaching periapsis.

Launch Window Approaching!

We are super excited that the Planetary Society’s Phobos LIFE (Living Interplanetary Flight Experiment) is about ready to launch to Mars’ moon Phobos and back. We have been working for years preparing this unique test of the effects of long term exposure to deep space on a wide variety of life.
