Much Ado about Pluto.

At a meeting of 2,500 astronomers in Prague to determine the appropriate definition of “planet” (in part due to the Xena challenge), it appears Pluto might soon be reclassified as a “dwarf planet” (as opposed to a “terrestrial planet” (Earth, Mars) or a “gas giant planet.” (Jupiter, Saturn)) rather than fully being demoted to non-planet status. Said one proponent of the plan: “I think we have done something that will make the Plutocrats and the children of the United States happy.

Martian Melee.

“‘We certainly have not convinced the community, and that’s been a little bit disappointing,’ said David McKay, a NASA biochemist and leader of the team that started the scientific episode.” Ten years later, CNN summarizes the simmering scientific dispute over a Martian meteorite, and the possible (albeit now seemingly quite unlikely) signs of life within.

Origin Story.

“Blue Origin proposes to launch its reusable launch vehicles (RLVs) on suborbital, ballistic trajectories to altitudes in excess of 325,000 feet (99,060 meters) from a privately-owned space launch site in Culberson County, Texas.” Some details emerge about the New Shepard Reusable Launch System, currently being developed by Jeff Bezos’ Blue Origin, where — full disclosure — one of my best and smartest friends from college is currently employed. “Also on the group’s to do list at the site is putting in place a vehicle processing facility, a launch complex and vehicle landing and recovery area, as well as an astronaut training facility, and other minor support amenities.”

The Rockets’ Red Glare.

A belated happy 230th Independence Day to you and yours, and here’s hoping the recent spate of scary news (North Korean missiles, incipent war in Gaza) didn’t detract too much from the festivities in your parts. (Also, with regards to more joyous fourth of july rocket launches, congrats to the crew of Discovery STS-121 on a successful return to space yesterday.)

Hawking Colonies.

“‘It is important for the human race to spread out into space for the survival of the species,’ Hawking said. ‘Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers we have not yet thought of.‘” Stephen Hawking makes the case for colonies in space. And Stephen Hawking is a very smart man (and, of course, not a bad MC.)

Great Eye in the Karoo.

The WP takes a gander at the Southern African Large Telescope (SALT), which “can see 13 billion years back in time, nearly to the big bang. With its 10-by-11-foot hexagonal mirror — the largest of its type in the world — SALT concentrates the faintest, most distant light in the universe. If a candle were to flicker on the moon, SALT could detect it.

Pas de vingt-sept. / Yuri + 45.

A very happy belated birthday to my sister Gillian, who turned 27 yesterday. (We celebrated on Monday, but, as y’all might know, I haven’t posted here since then.) Update: Also, a very happy Yuri’s Night to you and yours — tonight is the 45th anniversary of cosmonaut Yuri Gagarin’s first-ever trip into space, as well as the 25th anniversary of the first space shuttle mission. (By way of Blivet.)
