The following resources are available:
- The European Lunar Mission
SMART-1 is on its slow and winding
way towards the moon. At a steady pace the electric
propulsion system will get it there within 16 months.
At the same time the European Mars
Express has almost reached the red planet. The lander "Beagle 2"
is supposed to land on Mars at Christmas. See
where it is right now.
- The most important UNH participation in ESA Missions is on Cluster
right now. Cluster
has been following the recent solar storms closely.
- As we work several sample problems that allude to the Columbia Disaster
on Feb 2, here is the link to NASA's Columbia
Homepage. You find the complete accident panel report and a lot of more
useful and interesting information.
- Missed a spectacular view of the Leonid
meteor stream the last two years on November 18 and 19? Maybe there is
another chance this year. Leonids come every year and they may be full of
Here are some instructions that work for any meeor shower: Find a dark site.
Behind Kingman Farm in Madbury (UNH property) is a reasonable and close example.
NASA has set up an observation and tracking program, from which they broadcast
data online that are found at spaceweather.com.
If you want to get some general information on the Leonids, check out Gary
Kronk's wonderful website.
- Black Holes anyone? A
medium sized one inside a star cluster has been found. How do they do
this? We are just learning about the first piece of the puzzle, circular motion
as a clue.
- Want to see a
test run of the Shuttle main engine live?
- Faster than the speed of light (c)? Don't expect "Warp Drive"
and "subspace communication" soon!!
One of you pointed me to this interesting news item on a new
experiment with sending waves at 4 x c.
However, let me remind you, this doesn't invalidate Einstein's theory of relativity,
and it doesn't mean that we could send anything material faster than c. What
is going faster is the so-called "phase velocity" of the wave. The
velocity relevant to transmit information is the "group velocity"
of the wave, and that is still lower than c. You will learn about these things
in Phys 408. Even sending information will not be possible faster than c.
- News Flash: Latest Near Earth Object
(NEO) [Program for search of potentially dangerous near Earth asteroids
and such] appears to be a floating leftover from the Apollo Program. The
story on this object continues. The surface seems to match the paint of
the Saturn rockets, and it can be traced back to 1971.
- Here is something that the Computer Science students among you may be interested
in. To do the long and distant exploration we want to do,
a probe has to be "intelligent".
- Interested in the latest on Gravity? ESA
is preparing a probe to study Gravity effects in detail.
- Always be careful with recording and analyzing your data! The discovery
of Element 118 about 3 years ago has
just been retracted, and there is even evidence
of 'Data Fabrication'. That is one reason for discouraging to use pencils
in the Lab!
- Sometimes it happens: a louded discovery may not have been real. Apparently,
of the recently discovered planets may be illusions (yet only
some of them!!). [Link supplied by one of the students
in this class.]
- We briefly discussed in the first class why using solar power for deep space
missions is a problem. Find more
on power for space missions on a NASA Website.
The story goes on with other possible
methods of propulsion to get spacecraft to distant places.
- Here is a challenge for the engineers among you:
There has been an ongoing debate, whether a "space elevator" may
be possible. Some more serious
discussions have been underway lately.
- The 2001 Nobel
Prize in Physics was awarded for the study of the Bose-Einstein Condensate.
Learn also everything about the history of the Nobel Prize (100 years!), Laureates
and how it is awarded on the Nobel
- Here are some other Fun Links to look at:
- NASA presents interesting News
Items to the public on a daily basis
- Here is the "Space
Weather Information" (Solar Flares, Auroras, etc.)
Space Weather forecast and nowcast are available on the NOAA
- If you are interested in a zero-g adventure click
- We talked about the drag force in air in class, or its high tech name
"Aerobraking". It is used for the Mars
Odyssey mission. Watch for the events to unfold!
- See how a satellite is made to fall out of the sky using
- The Ulysses spacecraft passes
over the Sun's North Pole (for the second time). How did it get there?
We will talk about this trick in Chapter 10 of this course.
- Interstellar Pickup Ions move along with the solar wind in exactly the
same way as the valve on a bicycle wheel. We discuss this "rolling
motion" in Chapter 12 of the course. Enjoy a video animation of the
Pickup Ion motion in our Movie
Theatre. Then go down to "The Interstellar Gas Reveals Itself
Through the "Giant Swing". This animation was produced by a UNH Physics
You can find more on the Interstellar Gas on the
Interstellar Learning Page (An Online Tutorial).
The interstellar medium is a hot research topic in Prof. Möbius'
