Are astronomers finally going to push for a replacement for Hubble?

Astronomers are considering the merger two space missions to create a new optical/ultraviolet space telescope. The mission would be designed to do both deep cosmology and exoplanet observations.

The two communities would both like to see a 4–8-metre telescope in space that would cost in excess of $5 billion. “Our interests are basically aligned,” says [Jim Kasting, a planetary scientist at Pennsylvania State University]. Such a mission would compete for top billing in the next decadal survey of astronomy by the US National Academy of Sciences, due in 2020.

This story is big news, as it indicates two things. First, the 2010 Decadal Survey, released in August 2010, is almost certainly a bust. The budget problems at NASA as well as a general lack of enthusiasm among astronomers and the public for its recommendations mean that the big space missions it proposed will almost certainly not be built.

John Browning

An evening pause: As this year is the 100th anniversary of the M1911 pistol, probably the most popular pistol ever made, here is the part one of a four part documentary telling the story of the man who designed it, John Moses Browning.

The Hudson River School

An evening pause: Four minutes of paintings by artists from the Hudson River School.

Anyone who has ever hiked along or sailed on the Hudson River knows it to be one of the most beautiful rivers in the world, a quiet wide river winding south nestled between lush green hills. In the 19th century American artists Thomas Cole, Frederic Church and Albert Bierstadt among others were inspired by this beauty to paint some of the world’s greatest landscapes. If you can find the time, go to a museum that has some of these paintings and see them in person. They show us the majesty of the universe.

Update: Unfortunately, the video that I had originally embedded here disappeared from youtube last night. Here is the work of Alfred Bierstadt, set to the Connie Dover’s “Who will comfort me?”

Japan’s tsunami waves top historic heights

Japan’s tsunami in March produced the largest waves in history.

Some waves grew to more than 100 feet high, breaking historic records, as they squeezed between fingers of land surrounding port towns.

To me, however, this is the biggest takeaway:

Although terrible, the preliminary estimate also finds a better-than 92% survival rate for people living in coastal towns hit by the waves, Bourgeois says. “In that sense, given the magnitude of the unexpectedly large earthquake, things could have been even worse,” she says.

Shell abandons oil drilling plans in Alaska after EPA ruling

And Obama wonders why oil prices are high? Shell has abandoned its oil drilling plans in Alaska after an EPA regulatory board denied it permits. This after the oil company had spent $4 billion over five years developing those plans. To me, the quote below reveals much about the political agenda behind the EPA’s decision:

The Environmental Appeals Board has four members: Edward Reich, Charles Sheehan, Kathie Stein and Anna Wolgast. All are registered Democrats and Kathie Stein was an activist attorney for the Environmental Defense Fund.

Observations of Comet Hale-Bopp at 30 AU

In a paper published tonight on the Los Alamos astro-ph preprint website, astronomers described new observations of Comet Hale-Bopp at a distance of 30 astronomical units, or 2.8 billion miles, from the sun. Their conclusions:

  • These observations were the most distant detection of any known comet.
  • The comet’s starlike appearance and its drop in brightness since the last observations suggest that the comet has finally ceased, or is about to cease, all activity, and that they are now looking directly at the comet’s nucleus instead of the coma cloud surrounding it.
  • Nonetheless, the comet is brighter than expected, which also suggests that a thin layer of new ice covers its surface and thus increases its albedo.

To quote the paper, “Observing Hale-Bopp in a completely frozen state would be extremely important because a thick coma was constantly present during the entire appariation [Ed. the fly-by of the Sun]. The coma obscured the nucleus which was not observed directly. Lack photometric data of the bared nucleus, its size — one of the most important input parameter in activity models — remains uncertain.”

“We’re going all the way to Mars, I think… best case 10 years, worst case 15 to 20 years.”

Elon Musk: “We’ll probably put a first man in space in about three years. We’re going all the way to Mars, I think… best case 10 years, worst case 15 to 20 years.”

I believe him when he says he’ll launch his first manned mission in three years. However, I think he seriously underestimates the challenges of a mission to Mars, based on our present engineering abilities to build interplanetary spaceships.
