Stunning images of record-breaking skydiver, Felix Baumgartner, as he completes his last checklist, steps out of the capsule, and falls to earth. From a height of 128,097ft (24.2 miles; 39km). You can also see the flatspin that almost scuppered the attempt to break the sound barrier. The voice on CAPsuleCOMmunications is that of retired US Air Force Col Joe Kittinger who has been an integral part of Baumgartner’s record attempt team. Col Kittinger has held the record for the previous highest [102,800ft (31.3km)], farthest, …

The BBC report that the National Trust have amended the controversial exhibition at the new Giants’ Causeway interpretive centre following their announced review of the materials in the display. But have they fully addressed the problem? Not quite. Here’s how the revised controversial section of the transcript now reads Today there is a clear understanding among scientists that the heat of the earth was the driving force behind the formation of the Giant’s Causeway – and that the earth is far older than …

Jupiter swallows an asteroid – redux

As Space Weather notes Around the world, amateur astronomers have been scanning the cloudtops of Jupiter for signs of debris from an explosion witnessed by Dan Peterson and George Hall on Sept. 10th. So far the cloud layer is blank. “Several observers have now obtained excellent images on the second and third rotations after the fireball, and there is nothing new nor distinctive at the impact site,” reports John H. Rogers, director of the Jupiter Section of the British Astronomical …

Reading Frank McNally’s An Irishman’s Diary today – on the number of comments here, compared to the numbers here – all I can say is that, fortunately, I don’t suffer from ‘comment envy’… Much. From today’s Irishman’s Diary. And all right, Mars might be a minority interest on most websites, never mind sites focused on Northern politics. One couldn’t expect stories from the red planet to be anything like as pressing as events on the green and orange planets where …

“Thrust is engaged, and we are now climbing away from Vesta atop a blue-green pillar of xenon ions”

“the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink”

Private family man, engineer, US Navy fighter pilot, war veteran, civilian test pilot, astronaut, academic, businessman, reluctant hero, and the first man to walk on the moon, Neil Armstrong has died at the age of 82. Reg Turnill, who was the BBC’s aerospace correspondent at the time of the first moon landing, gives his thoughts. Nasa’s tribute is available here. And, via the Professor, Rand Simberg has a detailed biography that’s worth a read. For the 40th Anniversary of the launch of …

Curiosity drops in on Mars – in Hi-res

Pete Baker on August 23, 2012, 9:50 pm | Readers 53

Nasa’s mobile Mars Science Laboratory (MSL), the 900kg rover Curiosity, may have started roving on the surface of Mars, but there’s still room for more stunning video of its descent. In high-resolution. Audio from mission control can also be heard, counting down the critical events. Video from JPL News This movie from NASA’s Curiosity rover shows most of the high-resolution frames acquired by the Mars Descent Imager between the jettison of the heat shield and touchdown.

“Curiosity will soon have a different patch of ground beneath it.”

Pete Baker on August 22, 2012, 3:12 pm | Readers 47

Nasa’s mobile Mars Science Laboratory (MSL), the 900kg rover Curiosity, may have damaged one of two sets of wind sensors in its Rover Environmental Monitoring Station (REMS) during its dramatic landing on Mars, but it will still be providing daily weather reports from the Red Planet. And, as a JPL/Nasa press release noted yesterday – with moving images Curiosity will soon have a different patch of ground beneath it. Today, the six-wheeled rover wiggled its four corner wheels side to side for the …

Curiosity: “This is a very low-resolution panorama”

Having survived the seven minutes of terror, and landed successfully at Gale Crater, earlier this week Nasa’s mobile Mars Science Laboratory (MSL), the 900kg rover Curiosity, lifted its 2m high camera mast. And took a look at itself. [Image credit: NASA/JPL-Caltech] Then it took a look at its new surroundings. In colour. [Image credit: NASA/JPL-Caltech/MSSS] JPL have helpfully put together a video of the panoramic view.

Pete Baker on August 7, 2012, 4:02 pm | Readers 51

Another wondrous image from Nasa’s Mars Reconnaissance Orbiter (MRO). This time the High Resolution Imaging Science Experiment (HiRISE) camera onboard snapped the Red Planet’s “newest celebrity” – the Curiosity rover and its 51-foot-wide (almost 16 metre) parachute descending towards Gale Crater. [Image Credit: NASA/JPL-Caltech/Univ. of Arizona] From the Nasa/JPL press release “If HiRISE took the image one second before or one second after, we probably would be looking at an empty Martian landscape,” said Sarah Milkovich, HiRISE investigation scientist at NASA’s Jet Propulsion …

Dwarf Planet Gains Fifth Moon…

Bovine TB and badgers: “This approach has not been tried anywhere else…”

Pete Baker on July 15, 2012, 3:26 pm | Readers 65

The different approaches of the various administrations in the UK and Ireland to attempting to eradicate bovine tuberculosis [TB] in wild animals, specifically badgers, are worth noting. They are all in response to the EU Directive 64/432/EEC which, as the Welsh adminstration’s website notes, “requires Member States to provide plans showing how they will eradicate bovine TB in cattle.” In England, the UK government is pressing ahead with badger culling, despite the opposition of animal welfare groups like the RSPCA. In Wales, the Welsh …
