Flight path of Stardust capsule MAP

*Am linking it instead of posting it as an Image (too large). It's expected to shine
60 times brighter than Venus. Wow, wish I could see it.

On Sunday morning, Jan. 15th, between 1:56 and 1:59 a.m. PST, a brilliant fireball will streak over northern California and Nevada. It's NASA's Stardust capsule, returning to Earth with samples of dust from Comet Wild 2. The best observing sites are near Carlin and Elko, Nevada.

The fireball might be widely visible from parts of Oregon, Idaho and Utah as well as California and Nevada: observing tips. NASA is interested in videos and photos of the re-entry, which could help researchers learn more about, e.g., the physics of heat shields.

Observing tips

How to submit photos, video, etc.

Good luck to the mission and the team!

Stardust much like Genisis is a mid air capture, so how will it be visible at that hour...

Palomar · 2006-01-10 06:22:30

Stardust much like Genisis is a mid air capture, so how will it be visible at that hour...

*It'll be burning as it re-enters -- particularly in the high atmosphere. The mid-air capture will still be rather low to the ground by comparison, so it's got time to burn...

Stardust has already surprised the scientific community with its spectacular images from the navigational camera. Startling comet images were entirely unexpected

Nonetheless, its 72 images of comet Wild 2 have shaken up astronomers.
Scientists expected a mostly featureless surface, like those seen in close-ups of two other comets. Instead they saw bizarre geological features including 300-foot-tall spires, deep pits and craters.
The diameter of one huge depression takes up one-fifth of the 3-mile-wide comet. Named Left Foot, the crater has a flat, debris-less floor and nearly vertical walls.

Pretty great stuff for just a circling ice ball....

At 2:57 a.m. MST on Sunday, Stardust will slice through the atmosphere at an altitude of 410,000 feet over northern Nevada.
About two minutes later, when the probe reaches 10,000 feet, a drogue parachute will open, followed shortly after by the main parachute.

Woohoo! Just as A.C. Clarke had predicted comets would look like!

*Um...actually that (Wild 2's appearance) is old news. Some of these were posted in 2004 in the current (then) New Discoveries thread:

yay!

it worked!

Now all go and preregister at http://stardustathome.ssl.berkeley.edu/ to do some stardust hunting at home!

Sure, but I happened to be re-reading the 2061.. And his description of Halley... It's remarkably how it sounds like the description Spacenut quoted.

well worth the 6 MB download, snag it here

lots of interesting stuff being said on the commentary, anyone know what "Foresight", "Near spec" or "HDTV you have a strong wake" means?

Rxke · 2006-01-30 15:49:06

8)

Probably call-names for the different camera's, near spec being the plane (near spectator?) that's shooting the stuff in the .mov... HDTV, probably a HDTV-camera?

Seems there is a small mystery to the contents as returned by Stardust...

[url=http://www.msnbc.msn.com/id/11813637/]Comet dust samples offer puzzling mystery
How did material formed by fire end up on coldest reaches of solar system?[/url]

The samples include minerals such as anorthite, which is made up of calcium, sodium, aluminum and silicate; and diopside, made of calcium magnesium and silicate. Such minerals only form in very high temperatures.

Stardust Analysis Update May 12, 2006

One of the most exciting outcomes of the workshop was preliminary data suggesting that the comet is a mix of both stardust grains from other stars as well as materials formed in the solar system. As expected, there appears to be true stardust in Stardust.

Stardust@home tutorial now online ... real data promised real soon.

Microscope focusing is fun

Rxke · 2006-05-21 10:22:08

Ah! At last!

Was already wondering whether they'd actually do it.

You got a newsletter/update about it?

Stardust@Home update June 12, 2006

... the CCD camera taking the pictures of the aerogel at the Stardust@home lab at JSC is larger than the one initially planned for the job and takes pictures of larger aerogel segments. This means that it now takes about 5,500 movies to cover each aerogel tile, and the total number of movies needed to cover the entire collector is just over 700,000.
....
the day is fast approaching when Stardust@home will go live

"These calibration movies will be interspersed among the "real" Stardust@home movies that will be sent out to users around the world. By tracking whether any individual user detects or ignores the tracks in the planted movies, the Stardust@home team will get a pretty good idea of the user's level of skill or - just as likely - whether he or she is paying attention! Only results from users with a proven track record will be considered in pinpointing the location of real interstellar dust particles."

I think that's a good policy, you'll invariantly have idiots thinking they're funny, uploading nonsense results etc.

Today we officially begin the Stardust@home project with real data.

Rxke · 2006-08-02 00:55:32

I logged in some hours after it opened, and it was down Hardware difficulties...

Rxke · 2006-08-06 06:55:03

Finally got through the training session, I always was halfway there and then got a browser error, argh!

it's fun, if you like watching out of focus microscopic imagery

(Seriously: it's fun.)

Genesis Findings Solve Apollo Lunar Soil Mystery

The researchers conclude that the Apollo solar energetic particles do not exist. Both the Genesis and Apollo isotopic variations can be quantitatively explained by the fact that the Ne22 isotope is implanted deeper than the Ne20 isotope. Moreover, these findings indicate that there is no evidence for enhanced fluxes of high-energy solar particles billions of years ago compared to today.

Results are starting to be published.

Study Finds New Kind of Organics in Stardust Mission

Several of the analyses indicated that the samples contain polycyclic aromatic hydrocarbons (PAHs), scientists said. PAHs are molecules made of carbon and hydrogen that are common in interstellar space - and in barbeque grill soot.
Certain PAHs chemical varieties also contain oxygen and nitrogen. Some scientists believe that these PAHs variants exist in interstellar space as well. They are of interest to astrobiologists because these kinds of compounds play important roles in terrestrial biochemistry, according to Sandford.

Nasa's Genesis

Crashed probe yields Sun secrets

spent more than two years collecting oxygen from the outermost layers of the Sun. Scientists have measured the composition of oxygen at the birth of the Solar System.
These layers reflect the composition of the gas and dust cloud, known as the solar nebula, from which the Solar System formed 4.6 billion years ago.
The Earth, Moon and meteorites have widely differing proportions of the three oxygen isotopes: oxygen-16, oxygen-17, and oxygen-18. But the cause of these variations in different parts of the Solar System is unknown.
Measuring this primordial oxygen composition establishes an important baseline for understanding how the planets later evolved their different compositions of oxygen.
