If you have an interest in space exploration, you could not have picked a better time in history to be alive than right now. Data and images stream back to Earth daily at an unprecedented rate from robotic spacecraft active at far-flung destinations all over the solar system. To use an old political quote – we've never had it so good.

In the past 50 years we've exploded out of our "little blue dot" to leave boot prints on the moon, land on Venus, Mars and Saturn's moon Titan, and to orbit Mercury, Jupiter, Saturn, asteroids and comets, giving us incredible visual vistas of all.

What's missing is a detailed view of dwarf planet Pluto, but we'll have that when the New Horizons spacecraft gets there next year.

There's also another missing first about to be achieved next week – we're going to make a soft landing on the surface of a comet.

Comet Churyumov-Gerasimenko had to wait around patiently for billions of years for humans to discover it in 1967. However, it's been a much shorter wait for an opportunity to get up close and personal with it – we're landing a probe on the frozen dumbbell-shaped comet next Wednesday, November 12.

The Rosetta spacecraft, carrying the Philae probe, was launched  from French Guiana in February 2004 by the European Space Agency. It arrived in August this year and has already given us great views of the comet.

It was named for the Rosetta Stone found in Egypt that was crucial in deciphering ancient Egyptian hieroglyphics. Similarly the "lander" is named for the Nile River island Philae, where an obelisk also assisted in solving the puzzle of these symbols.

Czech Republic prepares own space program

The Czech Republic will have its own space program, according to the National Space Plan for 2014-2019 that the government approved at the beginning of the week, the daily Hospodárske noviny (HN) writes today.
The plan recommends that the National Space Agency, "a considerably smaller variant of NASA," be established to integrate the currently fragmented competences in this field, HN says.
So far the Czech Republic has participated in the European Space Agency (ESA) programs, the second most significant player in space exploration after NASA, which they joined in 2008. Czechs annually give some 14 million euros to the ESA.
The national space exploration program should have an annual budget of three to five million euros and last for five years at least.
It should complement the research carried out within the ESA. Consequently, the National Space Agency could fund the projects that cannot be paid by the ESA, HN says.
Jan Kolář, head of the Czech Space Office NGO, welcomes the idea of the national space program.
"However, it should focus on the preparation of research and development activities in technical sciences," such as the development of materials and various types of detectors and the aerodynamics area, Kolář said.
HN writes that one of the rare successes that Czech science and industry has recently scored in this filed is a micro-accelerometer used in the SWARM satellites that were sent into space last November. The device, developed by 15 Czech firms, measures slight and slow accelerations that influence the satellite's movement, which removes possible distortions in the magnetic field measurements, HN notes.
However, the successful Czech micro-accelerometer was rather an exceptional case, Kolář told HN.
He said Czech participation in the ESA is limited by finances on the one hand, and by skills on the other hand. "In addition, our participation in each program is confronted with other European countries," he added.
Under the approved national space plan, the Czech Republic's contribution to the ESA's optional programs must be doubled at least, HN writes.
The transitory six-year period, in which the Czech Republic as a new ESA member could use a special incentive program, ends this year. Almost a half of the Czech obligatory payments to the agency went to it.
After the Czech Republic, Poland and Romania entered the ESA, while Estonia and Hungary plan to do so, and now they can use the advantages of newcomers, HN adds.
