Mars - A Log of Expeditions
(in search of little green men)

21 Jan 2004, 03:49 UTC: NASA News
"NASA Mars Rover's First Soil Analysis Yields Surprises"
The United States is enjoying success with its Mars Lander, Spirit.
The grounded space craft is making use of its on-board microscope
and two different spectrometers. The spectrometers have been
designed for close-up study of the Martian soil and rocks. Tonight
Spirit seems preoccupied with a single football size rock. That rock
is being studied to the point that NASA has even named it. We
didn't make this up - though it sounds like something the old
men in the ham shack would do. Hold your breath......the football
sized rock is named "Adirondack".
 |
The first attempt of a space craft to connect with Mars was
the Japanese orbiter "Nozomi".
Launched on 04 July 1998, Nozomi was to go into an elliptical
orbit around the planet Mars to study the Martian Atmosphere and
ionosphere. Nozomi used up too much fuel trying to make
trajectory corrections to really have a chance at fulfilling its
mission. Nozomi's many times revised time table had the space craft
entering into orbit in early to mid December 2003. It is not known
if Nozomi kept traveling farther into space after passing Mars or if
the space craft crashed into the Red Planet.
|
 |
The Next attempt to connect with Mars came from the European Space
Agency (ESA) Mars Explorer. The Mars
Explorer was made up of two space crafts, One space craft
, an orbiter, kept the name "Mars Explorer" and entered in to its
orbit around Mars as expected. Another module of the original Mars
Explorer was designed to be a landing rover. The Landing Rover,
Beagle 2" detached itself from
the rest of the space ship on 19 Dec. On 25 Dec, Beagle 2 spread its
wings and attempted to parachute down to the Martian surface, Many
attempts to contact Beagle 2 have been made. Beagle 2 was even
forced into beacon status. While efforts to find Beagle 2
continue, chances of finding the space craft are very dim indeed.
|
 |
NASA's Mars Lander / Rover, named the "Spirit"
successfully landed in the Gusev Crater as planned on 04 Jan 2004.
Up to this point, Spirit has not gotten off of its
As Lander. A
protective bag has prevented Spirit from getting on with its 3-month
series of explorations and experiments.
|
 |
The Fourth vehicle bound for Mars is NASA's Rover, "Opportunity".
Opportunity is programmed to land on the opposite side of Mars from
Spirit. Landing of Opportunity is scheduled for
25 January 2004, at 05:05 UTC.
|
 |
07 Jan 2004, 02:05 UTC: The second NASA Mars
Rover is named " Opportunity" Space rover "Opportunity" is due to land
on Mar's surface on 25 January
2004, at 05:05 UTC NASA
( Date and Time Converted to Universal Coordinated Time from Pacific
Standard Time)
|
 |
NASA's first Mars Rover, "Spirit" landed on Mar's
surface 04 Jan 2004, at 04:36 UTC
|
 |
05 Jan 2004 :
NOTE:
We were asked by a reader earlier today how the European
Space Agency (ESA) chose the name "Beagle 2" for the ESA's
Mars Lander. The name was
chosen by the ESA because the lander was named after an earlier ship
used for exploring. The earlier ship was the "Beagle", used by
Charles Darwin.
|
 |
11 Dec 2003, 04:54 UTC: The last of the Great
Observatories makes a splash with quality of images transmitted back
to Earth. New images taken by Galex, have been released. Galex is
the last of the Great Observatories launched in NASA's Great
Observatories program.
 |
The Andromeda Galaxy was chosen to be in the first group of images
released to the public. Images
taken by Galex cover a wide range of
frequencies in the ultraviolet electromagnetic band. Galex was
launched last spring with the purpose of observing the universe
using ultra sensitive ultraviolet equipment.
Images of the Andromeda Galaxy were chosen for several
reasons. Not the least of them being that the Andromeda Galaxy is
the nearest neighbor to our own galaxy. Combination images were
taken by Galex using one near ultraviolet (red) and one far
ultraviolet (blue).
|
 |
The Web Site contains a number of pages on the history of the Great
Observatories Program, expectations of the program, communication
between Earth and the Observatories, and the mechanics of the Great
Observatory elements. Please use the Web Site's search engine to
help locate information. Searching with the word "galex" or
"great observatories" hopefully will help the reader find the
information wanted.

29 Nov 2003, 06:22 UTC : This Day in
History > 29 Nov 1961 >
Enos, a chimpanzee, was launched into an orbit circling the
Earth. Enos was the first animal sent into orbit by the United
Space. We remember this being a very "hot" topic in the news and on
the street.

 |
06 Nov 2003, 22:54 UTC: The largest
explosion to ever be witnessed in our solar system. You were there
to see it, and to be exposed to it. On 04 Nov 2003, Solar Region #
486 produced a X 28 Solar Flare.
 |
This flare has received a number of classifications all
the way up to X 40. The official word from the SEC on this date, is
that the flare originally classified as an X 17.1 flare now has the
official classification of X 28.
BELOW: Solar Flare. Largest ever recorded : X 28; Flare
occurred 04 Nov 2003. Image :
Steve Rismiller of
Milford, Ohio, captured this image of the flare in progress at 20:40
UT on Nov. 4th. It is the brighter of the two plumes rising above
the sun's limb. Courtesy spaceweather.com published 06 Nov
|
 |
Sound clips
of the X 28 Solar
Flare can be heard at
http://www-pw.physics.uiowa.edu/space-audio/.
They have been made
available to the public through NASA.
|
 |
An Image of the X 28 solar flare was captured by
NASA's Solar and Heliospheric Observatory (SOHO) spacecraft.
Due to the courtesy of NASA, we were able to obtain a copy of
the image - and have republished the SOHO image on the
Daily Photo 2 page.

22 Oct 2003, 20:40 UTC: Mars Scout Missions. It
is difficult to keep up with all of the present day Mars
missions. In the not too distant future, many "Scout"
missions, with a single mission or a small group of related
missions will be launched toward Mars. Keeping up with
all of the on-going Mars missions will be daunting. The Mars
Scout Mission program will use smaller, lesser
complicated space craft, that will only have to support one
objective. Cutting cost and decreasing the time from the start
of experimental design to analysis of data will make the Scout
Missions attractive.
 |
13 June 2001 : NASA issued a call for proposals for
Mars study missions.
"Perspective investigators were encouraged to propose diverse
spacecraft platforms for their science, including orbiters,
landers, rovers, airplanes and aerobots." NASA was to select
10 of the most promising concepts. Launch date was scheduled
for the year 2007.
|
 |
NASA has not forgotten the "Scout" project. We quit counting
NASA's news releases, conferences and internal selection
process papers at 33 "Papers" for the year 2003 only. There
have been many more during the past ten months. Additional
details have been published on the
NASA News page.

of orbiting four "Great Observatories" - starting with the
Hubble Telescope through the newest high tech observatory the
" Infrared Telescope Facility" . For additional information on
this innovative program go to Infrared

10 Sep
2003, 04:49 UTC: Noise coming from super
massive black hole. Chandra X-ray Observatory
have detected, "a noise about 57 octaves lower than middle-C,
is the deepest ever detected from an object in our
Universe". NASA The
black hole that sings base. We are still
researching some previously released data. Further details and
drawing will be added to the edited
article. |

31 Aug
2003, 01:24 UTC: The
season for auroras. Autumn is almost synonymous with
"aurora season" in the northern latitudes. It is strange how
the Earth can effect solar activity. But, truth is stranger
than fiction. According to NASA, there are twice as many
geomagnetic storms in the fall and spring as there are during
summer and winter. Interested in knowing more? Check out the
information published on Auroral
Activity page 3. Could care less? Then
please take a look around. It is not our policy to
publish "pages under construction". A major system crash
caused several hundred pages to end up scrambled and over
25,000 links to be broken. You always count how many still
need to be fixed. |

|
29 Aug
2003, 00:02 UTC: The Columbia Accident Investigation
Board released their final report on the 01 Feb 2003
disaster. The blame was placed equally on a piece of
foam hitting and breaking a reinforced carbon carbon shield -
letting hot plasma to enter the space craft. The
remainder of the blame was attributed to "NASA's organizational
culture". Links to
the various Columbia Accident Investigation are on this web
site's Shuttle
Press Release page. |
|
|
|
04 May 2003, 02:55 UTC: NASA and the Russian space
organization Energia
have signed agreements that spell out the place of amateur radio on
the station. A technical team, called ISS Ham, has been officially
established to serve as the interface to support hardware
development, crew training and on-orbit operations. |
|
|
21 Apr 2003,
22:10 UTC: Much earlier this year the Russian Government extend
an invitation to the Web Master to join a scientific panel to study
THE TUNGUSKA EVENT. This panel will meet in Russia from 25
June 2003, through 2 July 2003. A study of the 95 year
old mystery that took place in Siberia in 1908,
promises to be another "Don't Miss It" affair. Everybody that
is anybody will be there - except us of course. The Web Master is grateful to the Russian
Government for their kind invitation. A
quick click on this link will take you to some of the
details. |

09 Apr 2003,
20:03 UTC : NASA goes QRP with a
multimode transceiver and navigation devise. Update to article
NASA_QRP
page (11,839 bytes).
|
 |
Experiments
involving The Low Power Transceiver (LPT for the non-ham
readers - QRP for the rest of us) was completed. The purpose
of this experiment was to demonstrate that a single,
relatively small and light weight module could be used for
multi-mode simultaneous communications and navigation in
space. A true multi-use and multi-tasking module. The article
begins on the NASA_QRP
page (11,839 bytes). |
|
 |
As promised
some time ago, we are publishing results of some of the
experiments carried out by the Crew of the Space Shuttle
Columbia, during her final mission (STS-107). Generally, the
results will be published on the STS-107
Science page. | |
|
|
02
Mar 2003, 17:33 UTC : There are a number of high frequency
(HF) propagation forecasting models that are used by hams. Some use
a sunspot number - others use the equivalent 10.7 cm solar radio flux. IPS Radio and Space Services have
produced a conversion chart so you don't have to. When you need to
convert from the sunspot number to the equivalent solar radio flux
value, turn to the Solar Flux
page.

24
Feb 2003, 15:45 UTC : There has been quite a bit of press
stating that tile failure could not have caused the Columbia,
tragedy.
|
 |
On
13 Feb 2003, The Columbia Accident Investigation
Board (CAIB), published a statement that a "plasma" in the
Space Shuttle Columbia's Left Wheel Well may have caused
Columbia's destruction. The Board's statement went on to say
that "The
CAIB said heat transfer through the structure, as from
a missing tile, would not be sufficient to cause the
temperature indications seen in the last minutes of
flight." |
|
 |
NASA evidence from as early as 1988 may
contradict one of the latest statement made by
The Columbia Accident Investigation Board. The Third
Installment on Shuttle Tiles.
|
Readers
of this Web Site have the opportunity to study the various tiles
used on a Space Shuttle, tile construction, and previous tile
damage. Amazingly, much of the previous tile damage has been in the
same areas that were first damaged on Columbia.
You
can read facts about Shuttle Tiles and come to you own conclusions
as you listen to press releases. An article on Space Shuttle Tiles
begins on the Shuttle
Tiles Page 1. Additional installments to the article have
been published. A new installment is due today or
tomorrow. |
 |
24
Feb 2003, 15:45 UTC : We have published radar returns from
the National Weather Service showing the debris from Columbia, on
its final return to Earth on 1 Feb 2003. Radar returns over a 2 hour
period have been published from Weather Service Radars in Fort
Worth and Shreveport. The images are located on the STS-107
Radar page. Most of our readers can read radar returns.
Novice readers should be interested in the data displayed on the
radars. More advanced readers will be amazed at all of the
implications of these returns. |
 |
24
Feb 2003, 15:04 UTC : There is a lot more to the WWV (WWH)
signals than just Solar and Geophysical Indices. We have recently
pruned the WWV page because of its excessively long download time.
Still, additional information on standards produced by the WWV
(WWH) station(s) is available on the WWV page. Many standards
essential to amateur radio, and broadcast by WWV, are explained in
the More
to WWV section of the WWV
page. |

On
13 Feb 2003, The Columbia Accident
Investigation Board, published a statement that a "plasma"
in the Space Shuttle Columbia's Left Wheel Well may have caused
Columbia's destruction. The Board's statement went on to say
that "The CAIB said heat transfer through the structure, as from
a missing tile, would not be sufficient to cause the temperature
indications seen in the last minutes of flight."
Who said "one" missing tile? A small opening in a
number of areas mentioned in the Web's article would allow high
temperatures to enter the temperature sensitive wing or adjacent
structural areas
NASA evidence from as
early as 1988 contradicts one of the latest statement
made by The
Columbia Accident Investigation Board.
In 1988 NASA said : "During flight operations, damage has
occurred in the area between the RCC (Reinforced Carbon-Carbon TILE) nose cap and the nose landing gear doors from
impact during ascent and excess heat during
entry.
NASA indicated "The HRSI tiles (High-Temperature Reusable Surface Insulation
Tiles) in this area are to be replaced with RCC
(Reinforced Carbon-Carbon
Tiles)".
"Because
of evidence of plasma flow on the lower wing trailing edge and
elevon leading edge tiles (wing/elevon cove) at the outboard
elevon tip and inboard elevon, the LRSI tiles ( Low-Temperature Reusable Surface Insulation
Tiles) are replaced with FRCI-12 and HRSI 22
(the most dense form -and the most Efficient
High-Temperature dissipation type of High-Temperature Reusable
Surface Insulation Tile) tiles along with
gap fillers on Discovery (OV-103) and Atlantis (OV-104). On
Columbia (OV-102), only gap fillers are being installed in this
area." This was in the days of early Shuttle Flight. NASA |
|
 |
13
Feb 2003, 21:06 UTC : The first
installment in an article on the "Tiles that Cover the Space
Shuttle" has been published on the Shuttle
Tiles Page 1 web page. The article covers the types of tiles
that are used, the material that make up the various tiles, the
physical and chemical properties of the different tiles, where each
of the tiles are used, the manufacturing process for making each of
the different tiles, and the fastening process to hold the tiles in
place. The article also discusses the history of tile failures. This
original article is based on facts gleaned from NASA.

Jan 2003 04:50 UTC : We get a number of requests asking if there
is any where that the reader can go to find a table that converts 24
hour UTC (Universal Coordinated Time) into 12 hour time used in the
U.S. Time Zones. There certainly is. And, you can even print the
tables out if you wish. If this is something that you might find
helpful, go to the UTC
Conversion page. Tables for Standard
and Daylight
Savings Time are given. Should you have an interest in knowing
the time in various cities around the world, we have provided an International
Time and even a basic International
Weather page. Hawaii and Alaska were omitted from the tables.
Since the Webmaster is from Hawaii, he feels that the missing times
zones should be added. That being the case, we are sure that the
missing time zones will soon be added to the charts. There was an old
TV show where they asked : "why are we so nice"......answer "because
we like you". Editor

From the
SIDC (World Data Center for the Sunspot Index )
Provisional
International Normalized Hemispheric Sunspot Numbers for the month
of September are available on the SIDC Sun
Spot Page. The provisional data is furnished by the Solar
Influences Data Analysis Center (SIDC). A number of observatories and
universities calculate "smoothed" data for immediate use. Finalized
data is released several months later by the SIDC. This web site uses
"smoothed sun spot numbers and predicted solar indices published by IPS
Radio and Space Services. The SIDC sends the final data directly to this
web site. The data is again published in its polished form. Sun spot
numbers and geomagnetic indices are available from the year 1995 through
2009. Location of this data is also on the SIDC
Sun Spot Numbers
page.
Sun Spot Number and Solar Flux
There
are a number of high frequency (HF) propagation forecasting models that
are used by hams. Some use a sun spot number - others use the equivalent 10.7 cm solar radio
flux. IPS Radio and Space Services
have produced a conversion chart so you don't have to. When you need to
convert from the sun spot number to the equivalent solar radio flux value,
turn to the Solar Flux
page.
