Senior aerospace writer, Jeff Foust, provides an insightful perspective regarding the Antares and SpaceShipTwo commercial spaceflight mission failures

November 4

Excerpt from Jeff Foust’s article:

“The two accidents are linked by proximity in time, but in reality little else. Yet, there’s the danger that they will be tied together by the public, and by policymakers, by the fact that they were commercial, despite the otherwise vast differences. Already some people have raised questions about the capabilities of commercial space in general, for example, from these accidents. How the industry responds to and recovers from these accidents will shape those public and policy reactions in the months to come.”

“Solar storm nearly destroyed Earth two years ago” say NASA and scientists.

July 27

Yep:  Our entire electrical grid, orbiting satellites, Internet — the mainstays of modern life — were almost wiped out on July 23, 2012.

This is not hyperbole.  It almost happened.  And scientists believe that the odds of a solar storm with enough intensity to disrupt our lives over the next 10 years is 12%.

With all of the crises going on in the world, this little bit of news slipped through the cracks of the general media.  But it got the attention of lots of scientists and astronomers.

Watch Stunning First Simulation of Universe’s 13-Billion-Year Evolution (from National Geographic)

May 8

(National Geographic) “Until now, no single simulation was able to reproduce the universe on both large and small scales simultaneously,” Mark Vogelsberger of MIT and the Harvard-Smithsonian Center for Astrophysics, who led the simulation team, says in a statement. Using a computer program, the team grew the virtual galaxies in simulated time, starting from 12 million years after the big bang (which kicked off about 13.8 billion years ago), they report in a study released this week by the journal Nature.

Will Comet LINEAR produce a new major meteor shower in 2014?

May 4

comet-LINEAR-meteor-shower-orbit-graphicFrom EarthSky: The list of major meteor showers hasn’t changed much in recent decades, but it has changed a little. Meteor showers are part of nature, after all, and the list of major showers shifts and changes slightly, as all things in nature do, with one shower or another becoming more or less exciting as the years pass. In 2014, though, an exciting new meteor shower might come on the scene. This possible shower stems from a comet — Comet 209P/LINEAR — discovered in 2004. Comet 209P/LINEAR passed near the sun in 2009 and will pass near it again in early May, 2014. On the night of May 23-24, 2014 — if the predictions hold true — Earth might be sandblasted with debris from this comet, resulting in a fine display of meteors, or shooting stars. Mid-northern North American latitudes are favored. Follow the links below to learn more about the possible 2014 meteor shower of Comet 209P/LINEAR.

As for the predicted time of the shower … skywatchers in southern Canada and the continental U.S. are said by the experts to be especially well positioned to see the meteors on the night of May 23-24, 2014.

Would you like to fly to Mars? Here’s the next best thing…

January 19

time_capsule_to_mars_spacecraft_rendering_for_online_distributionMy company is a proud supporter of the international student team that’s planning to build and fly a small spacecraft to Mars. On board would be a two-inch-diameter titanium “time capsule of humanity” containing perhaps millions of digital photos, videos, audio files, and text messages from people all over the world — including you.

Your digital creations would be stored on new “quartz” media that, by some estimates, will survive on the surface of Mars for up to 300 million years.

This would be the world’s first interplanetary space mission led by a non-government team. Other key mission supporters include MIT and Explore Mars, Inc. Details of the mission can be viewed at this link.

While the students are working on the essential science, they are also looking for creative names for both the spacecraft and the Mars “time capsule” lander. The goal is to unleash the world’s creativity in every aspect of the program. The individuals who submit the chosen names will get special digital allocations in the time capsule’s quartz memory, as well as other unique tributes. To submit your name ideas, visit www.TimeCapuleToMars.com.

After 36 years and 12 billion miles, Voyager 1 crosses into interstellar space — becomes humanity’s “first true starship”

September 12

(CBS)  Covering nearly a million miles a day, NASA’s nuclear-powered Voyager 1 spacecraft, 36 years and 12 billion miles from Earth, has crossed the boundary between the sun’s influence and interstellar space, sailing into the vast gulf between the stars to become humanity’s first true starship, scientists announced Thursday.

“In leaving the (solar system) and setting sail on the cosmic seas between the stars, Voyager has joined the other historic journeys of exploration such as the first circumnavigation of the Earth and the first footprint on the moon,” said Voyager project scientist Ed Stone.

“This historic step is even more exciting because it marks the beginning of a new era of exploration for Voyager, the exploration of the space between the stars.”

See Friday night’s rocket launch to the moon from your backyard!

September 4

Most places on the central East Coast, all the way up to northern New England, will be able to see this Friday night’s maiden launch of America’s new five-stage “Minotaur V” rocket.  It will transport NASA’s Lunar Atmosphere and Dust Environment Explorer spacecraft (LADEE) to the moon.

The launch is scheduled for 11:27pm EDT from the Wallops Flight Facility in Virginia.  Use the associated graphics and your location to determine the number of seconds from launch the rocket will be visible, the direction to look, and how many degrees above the horizon the rocket will appear.   For instance, if you’re in New England, it should be visible 80 seconds after launch, towards the south, about 10 – 15 degrees above the horizon.

The weather forecast for Friday night, at the launch site and for viewing, looks great.

NASA lets Curiosity rover drive itself on Mars with first use of autonomous navigation

August 30

(JPL)  NASA’s Mars rover Curiosity has used autonomous navigation for the first time, a capability that lets the rover decide for itself how to drive safely on Mars.

This latest addition to Curiosity’s array of capabilities will help the rover cover the remaining ground en route to Mount Sharp, where geological layers hold information about environmental changes on ancient Mars. The capability uses software that engineers adapted to this larger and more complex vehicle from a similar capability used by NASA’s Mars Exploration Rover Opportunity, which is also currently active on Mars.

Using autonomous navigation, or autonav, Curiosity can analyze images it takes during a drive to calculate a safe driving path. This enables it to proceed safely even beyond the area that the human rover drivers on Earth can evaluate ahead of time.

On Tuesday, Aug. 27, Curiosity successfully used autonomous navigation to drive onto ground that could not be confirmed safe before the start of the drive. This was a first for Curiosity. In a preparatory test last week, Curiosity plotted part of a drive for itself, but kept within an area that operators had identified in advance as safe.   For the complete article, click here.  Image courtesy of NASA.

Astronaut nearly drowns on spacewalk outside of International Space Station

July 17

astronaut_spacewalk(USA Today)  Luca Parmitano of the European Space Agency got into trouble Tuesday. He was performing routine maintenance outside when water started trickling into the back of his helmet.

Spacewalking partner Chris Cassidy, a U.S. astronaut, took a look: “It’s a lot of water. His hair is saturated. It’s in his eyes as well as his nose and mouth.”

Mission Control was alarmed. NASA quickly aborted the spacewalk, cut it short by five hours. Parmitano and Cassidy were ordered back to the U.S. Quest airlock, where they would be out of the deadly vacuum environment in low Earth orbit, and into the relative safety of the space station.

The tide kept rising in Parmitano’s helmet during his 20-minute retreat to the airlock. And yes, NASA said he was in danger of drowning.

“Imagine you’re in a fish bowl,” said David Korth, NASA’s lead spacewalk flight director. “So, go stick your head in a fish bowl and try to walk around, and that’s not anything you would take lightly. And certainly, (spacewalking) is dangerous already.”

Parmitano could not hear or respond to questions after he reentered the airlock.

“Hey, Luca, from Houston, how’re you doing? Give us a status,” astronaut Shane Kimbrough said from Mission Control.

“Luca, did you hear that?” Cassidy asked.

He didn’t.

“Squeeze my hand if you’re fine,” Cassidy said, peering into his crewmate’s visor.

“I’m trying to see him,” Cassidy said. “He looks fine. He looks miserable, but OK.”

NASA is investigating. The initial suspect, a drinking water bag, no longer is thought to be the culprit. Jones, the veteran spacewalker, said his best guess is the leak came from Parmitano’s astronaut underwear.

Astronauts don form-fitting garments called Liquid Cooling and Ventilation Garments. They are cooled by chilled water lines running throughout. Jones suspects a rupture in a cooling line near Parmitano’s neck.

“The closest water line to where he was experiencing (trouble) is in the neck area of the LCVG,” Jones said.

Voyager spacecraft surfs solar system’s edge

June 28

[BBC News]  Ed Stone cannot say when the Voyager-1 spacecraft will leave the Solar System, but he believes the moment is close.  The latest data from this extraordinary probe, reported in this week’s Science journal, suggests it is surfing right on the very edge of our Sun’s domain.

The particles streaming away from our star have reduced to a trickle at its present location, 18.5 billion km from Earth.   Particles flying towards it from interstellar space, by contrast, have jumped markedly in the past year.  It all points to an imminent departure, which would make Voyager the first man-made object to cross into the space between the stars.

“It’s hard to imagine there’s another layer between the one we’re in and the outside,” Dr Stone told BBC News. “Topologically, it makes sense that this is the outermost layer. The only question is: how thick is it?”

Launched way back in 1977, the probe has now travelled so far from home that its constant chatter of data takes 17 hours to arrive at the US space agency’s receiving network. And chatter, it does.

Voyager’s instruments are busy sampling the far-flung environment. This has allowed Dr Stone and colleagues to map the shape and reach of the heliosphere – the giant bubble of charged particles blown off from our Sun.

Life on Mars? Curiosity proves Mars had the formula for life

March 12

(LA Times)  “Drilling into the Martian surface in search of signs of ancient life, the Mars Curiosity rover hit the jackpot, NASA said Tuesday.  The intrepid geologist on wheels analyzed a powdered sample pulled out of the Red Planet last month and  discovered some of the basic building blocks of life — and signs of a past environment capable of hosting primitive microbes.  ‘We have found a habitable environment that is so benign and is so supportive of life that probably if this water was around and you had been on the planet, you would have been able to drink it,’ mission lead scientist John Grotzinger, a Caltech geologist, said at a news conference in Washington, D.C.”   For the complete article, click here.   Image courtesy of NASA

Curiosity rover uses robotic arm to drill into Martian rock [DVICE]

February 10

[DVICE]  NASA reports the Curiosity rover has successfully drilled a hole, 0.63 inches wide and 2.5 inches deep into a sample of sedimentary bedrock. Ground control will now use the rover’s robotic arm to collect samples for processing in its self contained laboratory, looking for evidence Mars may have once harbored water.  The agency released a photo of the hole captured by Curiosity, and in a press release NASA’s associate administrator for the agency’s Science Mission Directorate, John Grunsfeld said, “The most advanced planetary robot ever designed is now a fully operating analytical laboratory on Mars.”

Sea Launch Zenit rocket with Intelsat spacecraft fails at launch [BBC News]

February 2

Sea Launch failureA Ukrainian-Russian rocket carrying a US-made telecommunications satellite has plunged into the Pacific Ocean shortly after launch.

The Zenit-3SL rocket, which was being operated from a floating pad south of the Hawaiian islands, failed 40 seconds after the lift-off at 06:56 GMT.

Officials say no-one was hurt as a result of the incident.

Intelsat-27, which weighed some 6.2 tonnes at launch, was to have provided direct-to-home TV services and mobile broadband connections.

Newly spotted comet may outshine the full moon — New Scientist

September 26

Newly spotted comet may outshine the full moonToday, the newfound comet seen [in the accompanying photo] is just a tiny dot in the sky beyond Jupiter. But in about a year, it might be one of the brightest objects in our night sky.

Vitali Nevski and Artyom Novichonok, of the International Scientific Optical Network (ISON) in Russia, discovered comet C/2012 S1 (ISON) on 21 September via images taken with a 40-centimetre reflecting telescope. Other sky-watchers soon spotted it, and the International Astronomical Union’s Minor Planet Center in Cambridge, Massachusetts, announced the find yesterday.

From the combined observations, astronomers were able to trace the comet’s recent path and find images of it dating back to late December 2011. From there they calculated a near-parabolic orbit that has comet ISON headed almost straight towards the sun.

Astronomers at the Remanzacco Observatory in Italy think that ISON will skim less than 1.4 million kilometres from the sun’s surface on 28 or 29 November.

The comet’s orbit also suggests it is a newcomer fresh from the Oort cloud, a distant halo of icy objects that surrounds the solar system. We last had a visitor direct from the cloud in 2009, when the green comet Lulin swooped in and sprouted two tails.

As with Lulin, the intense heat of ISON’s solar fly-by should vaporise the comet’s hard shell of pristine ices, releasing trapped dust that would help it grow an exceptionally bright tail. Astronomy Now magazine reports that comet ISON could even be brighter than the full moon around its closest approach to the sun.

Skirting our star means that, to viewers on Earth, the comet will appear close to the horizon and to the sun’s glare, making it difficult to see at first. ISON will fade but become easier to spot as it heads back towards the outer solar system. By 9 December it should be about as bright as Polaris, the North Star, according to Remanzacco Observatory astronomers. ISON should continue to be visible to the unaided eye until mid-January 2014.

But veteran astronomers warn that fresh comets with orbits that almost skim the sun are notoriously unpredictable. Results can range from the spectacular comet McNaught of January 2007 to the infamously fizzled comet Kohoutek of 1973.

Spheres spark new Martian mystery – Cosmic Log

September 14

Eight years ago, NASA’s Opportunity rover came across strange-looking spheres that were nicknamed Martian blueberries — and now the rover has sent back a picture showing a different flavor of Marsberry that has the experts scratching their heads.

“This is one of the most extraordinary pictures from the whole mission,” Cornell astronomer Steve Squyres, the rover mission’s principal investigator, said today in a news release.

The golf-cart-sized Opportunity rover used the microscopic imager on the end of its robotic arm to take a super-close look at the spherical shapes. These particular berries, measuring as much as one-eighth of an inch (3 millimeters) in diameter, cover an outcrop called Kirkwood in the Cape York segment of Endeavour Crater’s western rim.

“Kirkwood is chock full of a dense accumulation of these small spherical objects,” Squyres said. “Of course, we immediately thought of the blueberries, but this is something different. We never have seen such a dense accumulation of spherules in a rock outcrop on Mars.”

35 years after launch, Voyager 1 is heading for the stars

September 4

35 years later, Voyager 1 is heading for the stars - BusinessweekPASADENA, Calif. AP — Thirty-five years after leaving Earth, Voyager 1 is reaching for the stars. Sooner or later, the workhorse spacecraft will bid adieu to the solar system and enter a new realm of space — the first time a manmade object will have escaped to the other side.

When NASA’s Voyager 1 and Voyager 2 first rocketed out of Earth’s grip in 1977, no one knew how long they would live. Now, they are the longest-operating spacecraft in history and the most distant, at billions of miles from Earth but in different directions.

They’re still ticking despite being relics of the early Space Age. Each only has 68 kilobytes of computer memory. To put that in perspective, the smallest iPod — an 8-gigabyte iPod Nano — is 100,000 times more powerful. Each also has an eight-track tape recorder. Today’s spacecraft use digital memory.

Wednesday marks the 35th anniversary of Voyager 1’s launch to Jupiter and Saturn. It is now flitting around the fringes of the solar system, which is enveloped in a giant plasma bubble. This hot and turbulent area is created by a stream of charged particles from the sun.Outside the bubble is a new frontier in the Milky Way — the space between stars. Once it plows through, scientists expect a calmer environment by comparison.

When that would happen is anyone’s guess. Voyager 1 is in uncharted celestial territory. One thing is clear: The boundary that separates the solar system and interstellar space is near, but it could take days, months or years to cross that milestone.Voyager 1 is currently more than 11 billion miles from the sun. Twin Voyager 2, which celebrated its launch anniversary two weeks ago, trails behind at 9 billion miles from the sun.

As commercial space race intensifies SpaceX, Virgin find they have company | Ars Technica

August 25

While Earthdwellers cast their eyes to Mars this week and waited for news from NASA’s Curiosity, lots of action took place closer to home, where the commercial space market has seen progress from every direction. We’ve rounded up a short summary of what happened back on the home planet.

Sierra Nevada’s Dream Chaser spacecraft team held its Program Implementation Plan Review in Colorado this week, the first milestone in its CCiCap list.

SpaceX completed its COTS (Commercial Orbital Transport Services) agreement this week with a certification from NASA, clearing the way for SPX-1, its first standard cargo flight to the International Space Station.

Orbital Sciences was also slated to fly its Antares rocket for the first time in early October, but there’s no word yet on whether the traffic jam that’s holding up SpaceX will bump them again. Antares is Orbital’s COTS vehicle and a competitor of SpaceX’s Falcon. It has been delayed several times due to launchpad construction at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Virginia.

XCOR Aerospace announced this week that they’ll build a new spacecraft factory in Brevard County, Florida, to build its Lynx 2-person suborbital spacecraft. Lynx takes off and lands horizontally and requires a runway, which in Florida means the Shuttle’s landing strip at Kennedy Space Center.
