NASA’s Phoenix lander detected snow falling from clouds 2 miles high.  While none reached the ground, it confirms water still precipitates from the sky in at least one form.

Folks continue to modify their Toyota Priuses to get even more performance from battery technologies.  At $7500 a pop, it’s not for everyone, but the engineering hurdles to make a car run exclusively off electricity if the driver wants has been jumped over time and time again.  My next car will be a hybrid at a minimum.  If I can convert it to be a plug-in, all the better.

A critical component of the Hubble has failed.  The Control Unit/Science Data Formatter is no longer working, meaning data can’t be sent to the ground.  A backup version is on-board, but scientists need to see if it can be brought online.  Another backup is located at the Hubble operations center.  Engineers will see if it can be made flight ready and if the system can be replaced in-flight.  Astronauts scheduled for the original Hubble repair mission will likely have to do some additional training also.  All this means the Hubble repair mission is likely to be delayed until January or February of next year.  The next International Space Station construction mission would then be moved up to mid-November.

SpaceX has successfully become the first private entity to put a liquid-fueled booster in Earth orbit.  It took four tries, but Falcon1 achieved the mark Sunday.  More Falcon1 launches are scheduled, with one next year to launch a Malaysian satellite.  SpaceX is also planning a mid-2009 launch of Falcon9, which could help deliver supplies to the International Space Station while NASA is without a vehicle between shuttle retirement and Orion coming online.

Has the next solar cycle begun?  After a brief time of no sunspots, one has developed on the sun’s surface.  If more sunspots develop in the relative near future, Solar Cycle 24 will have begun.

NASA’s Phoenix Mars Lander could get a mission extension. Managers are asking for 30 more Martian days of funding to continue digging in search of evidence of water and possibly life. As the article mentions, the rovers Spirit and Opportunity are still chugging around four years after landing. That won’t happen with Phoenix, but another 30 days of science would be awesome.

A planned Canadian satellite could search for Near Earth Objects (small asteroids, etc.) as well as U.S. and Canadian artificial satellites. To do both jobs, a new attitude control and tracking system will have to be developed and tested.

Space shuttle Atlantis’ launch date, originally scheduled for Oct.8, could be accelerated by four days.

Virgin Galactic unveiled its new mothership, WhiteKnightTwo, to the public on Monday. A large number of test flights, at least 40 according to Burt Rutan, will be necessary before the craft is used to launch passengers aboard SpaceShipTwo 65 miles above the Earth’s surface. When I have the money…

The International Astronomical Union continues to work on language and definitions describing bodies in our solar system.  Planets, dwarf planets, plutoids and major planets are on the latest list.  This is science folks: topics are under constant observation and change.  It part of what makes science so fun.
