Animation of the five closest-approach Hartley 2 images ( KFC Chicken leg or cucumber?)

Please visit Tha Planetary Society

Those of you who follow my blog must have known this was coming: now that I got all five new Deep Impact images of Comet Hartley 2 posted and explained, I had to make an animation. Here they are. I rotated them all counterclockwise by a quarter turn and aligned the frames, but otherwise did no processing.

Animation of Deep Impact close-approach images
About an hour after its closest approach of Hartley 2, Deep Impact downlinked five precious images taken during the nearest part of its flyby. The top two images were taken 82 and 16 seconds before closest approach, and the bottom three 18, 57, and 117 seconds after closest approach (image times are 13:58:07, 13:59:13, 13:59:47, 14:00:26, and 14:01:26 UTC on November 4, 2010). They show a very active comet with numerous jets. Credit: NASA / JPL / UMD / animation by Emily Lakdawalla 

DID EARTH ENCOUNTER PIECES OF AN ALIEN VISITOR LAST NIGHT?

This is how Comet Hartley 2 might appear in the eyepiece of a large amateur telescope. Located about eight degrees (16 full moon diameters) away from the bright star Procyon as it leaves the constellation Gemini, Comet Hartley will be best viewed high in the sky just before dawn.

Did Earth encounter pieces of an alien visitor last night? Apparently so! It appears tiny pieces of Comet Hartley 2 may have presented a spectacular and startling sky show across the country yesterday. NASA meteor experts had predicted it was a long shot, but the evenings of November 2nd and 3rd might display a meteor shower from dust which puffed off this visiting comet as it passed within twelve million miles of Earth. And indeed, the Center for Astrophysics has collected several sightings of bright meteors called fireballs, which result when comet dust burns up in Earth's atmosphere.

Helga Cabral in Seascape, California, reported after 9 pm last night, "I saw a bright white ball and tail, arcing towards the ocean. It was quite beautiful and it looked like it was headed out to sea and so picture perfect it could have been a movie!" Three thousand miles away just north of Boston, Teresa Witham witnessed a similar cosmic event. "I was in the Revere area about 7:15 last night, driving north on Route 1, when a brilliant object with a tail passed in front of me -- very similar in appearance to a shooting star but it appeared much lower to the Earth than a typical shooting star would be. If it weren't for the fact that I had my daughter with me, I'd begin to believe I'd imagined it."

Comet Hartley 2 has put on quite a nice show for amateur astronomers over the past few weeks, sporting a vivid green coma or halo around it and a golden auburn tail of dust. NASA's Deep Impact/EPOXI probe will present dramatic close-up images of the comet when it zooms past the nucleus on November 4th.

When a comet approaches the Sun, it heats up unevenly, throwing off dust, ice and bits of rock. When the Earth encounters some of this space debris, it is seen as a beautiful meteor shower.

"Many people don't realize that the famous periodic meteor shower in August, the Perseids, is the remains of Comet Swift-Tuttle and the Orionids, appearing in late October, are leftovers from Comet Halley," said Tim Spahr, Director of the Minor Planet Center at the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA.

So for the next two evenings, we may see more of Comet Hartley 2. And if you have dark skies and a small telescope or binoculars, try to find Comet Hartley 2 itself. It will be near the bright star Procyon in the constellation Canis Minor near Orion the Hunter, which will be high overhead in the early hours before dawn.

ODIN SATELLITE OBSERVES WATER IN COMET 103P/HARTLEY 2

d’Etudes Spatiales/Observatoire de Paris.

The Odin satellite observed Comet Hartley 2 almost continuously from 29 October to 1 November. The water signature (line) was easily detected. Its extension and space distribution is shown on a map (Fig. 1). The production of water derived from the observations ranges from 180 to 300 kg (400 to 660 lb) per second.


This production of water (Fig. 2) is rapidly varying with time. This is in line with variations reported from other means of observation. It may be related to the rotation of the comet's nucleus, for which periods around 17h have been reported.

Comet 103P/Hartley 2 is a Jupiter-family comet orbiting the Sun close to the ecliptic plane, with a period of 6.5 years. Its return this year is exceptional. It passed perihelion on 28 October at 1.059 AU from the Sun (158 million km; 98 million miles) and on 20 October, it came close to the Earth, at only 0.121 AU (18 million km; 11 million miles). Furthermore, it is the target of NASA's mission EPOXI, which is to fly by the comet on 4 November.

At this occasion, this comet is the object of an intense, international campaign of observation which mobilizes all major astronomical resources, including the Herschel Space Observatory. The Odin satellite is participating to this campaign.

The Odin satellite is a small spacecraft, orbiting the Earth, designed and built by Sweden, in collaboration with Canada, Finland and France. It was launched in February 2001. Aimed for studying both the Universe (astronomy) and the terrestrial atmosphere (aeronomy), it allows for the observation of a number of molecular lines, at radio (submillimeter range) wavelengths, otherwise not accessible from the ground: in particular the fundamental water line at 556.9 GHz.

Odin is thus well suited for the study of water, the main constituent of cometary ices, released as water vapor following heating of cometary nuclei by the Sun.

Since its launch, Odin has observed about 15 comets. Now closed for astronomical observations, the Odin satellite concentrates on aeronomical studies, except for special occasions such as the passage of Comet Hartley 2.

So 10:30 (Maandag 1 November) bel my broer Ben uit Johannesburg. "Daar's `n sirkel om die son! Gaan kyk! Ek besef dadelik wat dit is, want die vorige een was `n sirkel om die maan (Sien blog). Tog loer ek by die venster uit en sien niks. Dit het toe die vorige dag by hulle gereën en hoë cirrus wolke was nog in die lug. 

• (Sien blog vir sirkel om die maan).

Skaars `n halfuur later storm  kollega Nellie Friend  van die Universiteit by my in en vertel van die kring om die son, maar die son is te skerp en sy  kan dit nie sien nie. Haar seun, Roland Friend van Secunda het gebel en gesê sy moet kyk. Hy het ook die foto hier bo geneem en vir ons aangestuur. 

Ek kan nie die foto dadelik op die blog laai nie en stuur dit vir Auke Slotegraaf in die Kaap. Hy is toe in dieselfde bootjie - besig om van internet versakaffers te verander. Hy kon toe darem die foto gistermiddag op sy blog gaan laai.

Besoek dit gerus: psychohistorian.org en lees meer oor die verskynsel.

For the 40th time in the past decade, a Russian cargo freighter has arrived at the International Space Station carrying vital supplies to feed the needs of the orbiting laboratory and its resident crews. But this docking required the intervention by one of the most experienced cosmonauts.

The Progress M-08M spacecraft, flying on autopilot, performed a flawless rendezvous with the space station after a three-day journey from the Baikonur Cosmodrome launch pad, but some yet-unspecified problem at the last minute prompted cosmonaut Alexander Kaleri to take over manual control and guide the vehicle to docking.

The successful linkup to the Pirs docking compartment came at 12:36 p.m. EDT (1636 GMT) while soaring 220 miles over western Kazakhstan.

Hooks and latches were engaged a few minutes later to firmly secure the 24-foot-long craft to the station.

The Expedition 25 crew of commander Doug Wheelock, fellow NASA astronauts Shannon Walker and Scott Kelly, and Russian cosmonauts Fyodor Yurchikhin, Oleg Skripochka and Kaleri plan to open hatches and enter the Progress later today.

The cargo includes 2,804 pounds of equipment, food, clothing and life support system gear, 1,918 pounds of propellant to replenish reservoirs that feed the Russian maneuvering thrusters, 498 pounds of water and some 110 pounds of oxygen and air for the station's atmosphere.

The Progress was launched Wednesday atop a Soyuz rocket from Baikonur Cosmodrome, reaching a preliminary orbit of 151 by 120 miles. A series of precise engine firings propelled the freighter on the orbital chase.

After arriving in range of the space station today, the vessel began a flyaround maneuver to get lined up with the docking port and then executed a roll maneuver to properly orient its solar wings with surrounding structures around the Pirs module.

A brief stationkeeping hold with about 650 feet between the freighter and station allowed Russian flight controllers to assess systems before giving approval to commence the final approach.

It was during stationkeeping that Russian flight controllers in Moscow instructed Kaleri to activate the TORU manual docking equipment and take over the piloting tasks from the Progress' autonomous KURS system.

Encounters with Comet Hartley 2

by Greg Bryant and the editors of Sky & Telescope

The diffuse coma of Comet Hartley 2 was more than 1° wide on October 13th, when Nick Howes took this image with a 4-inch apochromatic refractor in Wiltshire, U.K. Stars are shown by short exposures in the blue and green channels; the comet is shown as a full-color long exposure. Howes has also been remotely operating the 2-meter Faulkes North Telescope in Hawaii. Using this he has measured the rotation rate of the comet's nucleus to be 19 ± 1.5 hours.

Comet Hartley 2 a "6-inch spinning cucumber!"

 Exactly one week before the world gets a new look at comet Hartley 2 via NASA's EPOXI mission, observations of the comet by the Arecibo Planetary Radar in Puerto Rico have offered scientists a tantalizing preview. 

"It kind of looks like a cross between a bowling pin and a pickle," said EPOXI project manager Tim Larson of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Only it's about 14-thousand-times larger and hurtling through space at 23 miles per second." A new image is online at http://www.naic.ed … ~pradar/103P . 

Scientists using Arecibo's massive radar dish began observations of Hartley 2 on Oct. 24, just four days after the comet made its closest approach to Earth since its discovery in 1986. (On Oct. 20, the comet came within 17.7 million kilometers, or 11 million miles, of Earth). The observations are scheduled to continue through Friday, Oct. 29. 

During the Nov. 4 flyby, the cameras aboard the EPOXI mission spacecraft will get within 700 kilometers (about 435 miles) of the comet.\

"Observing comet Hartley 2 from the Earth with radar was like imaging a 6-inch spinning cucumber from 836 miles away," said Jon Giorgini, a scientist at JPL and a member of the Arecibo team that imaged the comet. "Even without all the data in, we can still make some basic assertions about Hartley 2. Its nucleus is highly elongated and about 2.2 kilometers [1.4 mile] long, and it rotates around itself about once every 18 hours. In addition we now know the size, speed and direction of particles being blown off the comet, and we immediately forwarded all this information to the EPOXI team."

Space station on to the 2nd decade (ISS)

The second decade of a new era in human history -- when not everyone lives on our home planet -- begins Nov. 2, 2010, as the International Space Station crosses the 1.5 billion mile mark of its travels with six residents on board and six visitors en route. 

 On Oct. 25, the station also set a record for being the longest continuously inhabited spacecraft. On that day, the International Space Station eclipsed the previous record of 3,644 days set by the Russian Mir Space Station. With each new day, NASA and its partners are pushing the envelope of human achievement in space into uncharted territory.

Ten years ago, Bill Shepherd, Yuri Gidzenko and Sergei Krikalev launched into history as the first crew to live on the International Space Station. They blasted off from the Baikonur Cosmodrome in Kazakhstan on Oct. 31, 2000, and docked with the station two days later. From the moment the hatch of their Soyuz spacecraft opened and they entered the fledgling space station, there have been people living and working in orbit, 24 hours a day, seven days a week, 365 days a year.

“As we look forward to the next 10 years, taking us through 2020, the space station will serve many roles,” said Mike Suffredini, International Space Station program manager since 2005. “With its permanent human presence, it will serve as a foothold for long-term exploration into space, being an integral part of testing human endurance, equipment reliability and processes essential for space exploration.”

Before his launch, Expedition 1 commander Shepherd explained that the station “gives us unique access to the space environment where we hope we can do very interesting and productive research, but it really means we [will] develop a lot of the capabilities and technology that’ll allow humans to go elsewhere away from the planet.”

Leaks delay final launch of space shuttle Discovery

The launch of the space shuttle Discovery on its final scheduled mission has been delayed by at least 24 hours until Tuesday because of a leak in a pressurization system, NASA said.

"We have developed two leaks on the pressurization system on the maneuvering system of Discovery on the right side," Kennedy Space Center spokesman Allard Beutel told AFP on Friday.

Fixing the shuttle and getting it ready for take-off would take until "Tuesday at the earliest," the spokesman added.

Discovery and its crew of six astronauts had been scheduled to launch Monday on its last mission to the International Space Station, but that now has been reset for 4:17 pm (2017 GMT) Tuesday, assuming repairs are successful, NASA said.
