The Fall Edition of Space Lifestyle Magazine has just been issued. For my first article in the electronic magazine, I took a trip to the Space Exploration Technologies (SpaceX) headquarters in Hawthorn, near LA to have a tour around the site. With a special thanks to Diane Murphy, SpaceX Vice-President of Marketing and Communications, I fulfilled every space geek’s dream to see Falcon 1 and Falcon 9 rockets being built, plus being within touching distance of the Dragon module (to undergo space tests in 2009). For me, the most significant moment was to see one of SpaceX’s complete Merlin-1C engines sitting on the rocket workshop floor, an amazing piece of engineering.
In this quarter’s edition of SLM, my Universe Today colleague Nancy Atkinson (Editor-in-Chief of the magazine), takes an in-depth look into the space policies of both Presidential Candidates, Barack Obama and John McCain (although we now know how that turned out!), and my SLM co-writer Katie Kline gives a rundown of what’s new and exciting in the world of space travel. It is an inspiring magazine with lots more articles and columns throughout its 70 pages…
It looks like the Early Ammonia Servicer (EAS) re-entered pretty close to Australia in the end. The US Space Command released the co-ordinates of 48° S 151° E as the most likely EAS re-entry fireball. This is only 550 km south of the southern-most region of Australia, Tasmania. An eagle-eyed reader of the Universe Today also noted that the original location of re-entry being in the Indian Ocean was incorrect. As the Indian Ocean is separated from the Pacific Ocean at the 147° meridian, the 151° longitude is obviously well within the South Pacific.
All articles now corrected. At least the EAS didn’t drop into Sydney harbour… now that might have caused a “diplomatic incident”.
It looks like the Early Ammonia Servicer (EAS) that has been orbiting Earth for the past 15 months had a fight with the Earth’s atmosphere… and lost. Due to re-enter at some time today (Sunday), an eagle-eyed amateur astronomer noted when the EAS was due to make an orbital pass… but the ammonia-filled space station cast-off missed its November 2nd appointment.
Thomas Dorman of Horizon City, Texas, observed the object fly overhead on November 1st. Dorman was using a low-light camera to attempt to spot the speeding debris earlier today, “but the EAS did not appear,” he said. “I think it is safe to assume EAS has reentered.”
It is most likely that the EAS disintegrated and any surviving bits either fell into an ocean (somewhere) or dropped harmlessly in a sparsely populated region. No reports of a fireball or half a refrigerator randomly dropping into someone’s back yard have surfaced, so my money is on NASA’s reckoning that the EAS would fall harmlessly into water.
US Space Command reports that the Early Ammonia Servicer (EAS) probably reentered Earth’s atmosphere on Nov. 3rd at 04:51:00 GMT +/- 1 minute over the following coordinates: 48° S, 151° E. That would place the fireball over the Indian Ocean [Pacific Ocean] south of Tasmania where sightings are unlikely.
Somewhere, sometime today, the Early Ammonia Servicer (EAS) will drop to Earth at 100 mph.
A huge piece of space junk discarded from the space station in 2007 will drop through the atmosphere some time today (Sunday). The Early Ammonia Servicer, otherwise known as the EAS, was detached from the orbiting outpost as its services were no longer required. The double-refrigerator-sized piece of equipment weighs 635 kg (1400 lb) and is filled with toxic ammonia. Although NASA believes most of its mass will disintegrate during re-entry, there’s a real chance of up to 15 pieces of the EAS reaching the ground, the largest piece could weigh up to 17.5 kg (40 lb).
But here’s the funny thing, as the EAS is currently skirting along the outermost reaches of the atmosphere, we are uncertain as to when, or where, the re-entry will take place. NASA and U.S. Space Surveillance Network scientists have done well to narrow the re-entry window down to one day. Fortunately, 70% of the planet is covered in water, so we should be fine. But should any parts of the EAS find solid ground, NASA has warned that we shouldn’t approach any suspicious-looking (and probably steaming) bits of meteorite in case the EAS still has some ammonia on board… Continue reading “Watch Your Heads! Space Station Junk to Hit Earth Today”
In only three days, the USA will take to the polls and vote in their next president. Presently, Sen. Barack Obama (Democrat) is holding the lead in the opinion polls, in front of Sen. John McCain (Republican). Opinion polls, although indicative of the current mood of voters, are by no means fool-proof, this election could go either way.
This is the first US election I have been in the country for, and from what I’ve seen and heard from both leading candidates have been worrying yet significant. It is no secret that the US is suffering every “crisis” in the book (housing crisis, credit crisis, economic crisis, health care crisis…), but the one election issue that is key in my mind is the growing space exploration crisis. Whilst this may be low on the list of national priorities at the moment, the next few years will be critical to the international balance of space exploration dominance for decades to come. The next few years, if unchecked, could be the most challenging period NASA has ever faced.
After an uncertain couple of days, NASA has regained contact with the ailing Mars lander. Yesterday, scientists announced they were having difficulty communicating with Phoenix after the on board electronics were switched into “safe mode” on Tuesday. It seems likely that the robot was switched into this low-energy state due to the increasingly cold weather — plus a Sun-blocking dust storm — triggering a low-power fault.
Although scientists were concerned they may not regain communications with the lander, they were able get in touch with Phoenix late on Thursday during a two hour period when the lander’s electronics were powered up. Now scientists know that Phoenix will automatically reboot itself every 19 hours, and then power up again for two hours to carry out very limited science duties.
NASA was able to transmit commands via NASA’s Mars Odyssey orbiter which passed overhead during this two-hour period of opportunity. This goes to show how little solar energy is being collected from the meagre sunlight as Mars enters winter (the Sun is very low on the Martian horizon, and it will soon drop out of sight, sealing the fate of Phoenix).
However, before Phoenix succumbs to a low energy coma, NASA is trying to get as many science activities out of it before it is frozen solid.
It also seems fitting that the highly successful NASA mission should come back from the brink of death on Halloween. So, “Happy Halloween Phoenix!” We all hope you last a few more weeks…
Late on Tuesday, NASA’s Phoenix Mars lander entered “safe mode.”
Before this, NASA scientists were working to conserve power by shutting down non-critical systems. By powering down instrumentation such as the heaters that warm Phoenix’s robotic arm, valuable energy was hoped to be saved, perhaps giving the lander some extra time to carry out its final experiments before complete loss of sunlight as Mars’ northern hemisphere enters winter. But it seems that a possible dust storm and the falling temperatures (down to -96°C) may have caused a low-power fault, triggering the precautionary safe-mode.
Although scientists were optimistic about communicating with its on board systems, to send commands to bring Phoenix back online, it seems time (and energy) has run out… Continue reading “Has Phoenix… Died?”
On September 28th, Elon Musk proved he wasn’t a dreamer and blasted the world’s first commercial rocket — Falcon 1 — into Earth orbit. SpaceX have put their previous launch failures behind them, rightfully filing them under “learning curve.”
The team at NASA’s Phoenix Mars mission control have started to switch off instrumentation on the robotic lander after five months of astounding science (even after surviving the “7-minutes of terror” on May 25th, finding proof of water, overcoming technical issues and multiplying our understanding of the chemistry on an alien planet). Plus the armada of satellites orbiting the Red Planet. Oh yes, and those crazy rovers that just keep on rollin’.
So with that in mind, let’s consider the Armadillo Aerospace space tourism concept (pictured above). Call me old fashioned, but I’m a little worried about spaceships without wings. Yes, I know we are always sending rockets into space, delivering crew and cargo to the space station. The Soyuz vehicle doesn’t have wings and the cone-like re-entry capsule so many other space vehicles are based on are reliable modes of transport. But there’s something about the “controlled ascent” Armadillo design that makes me a little uneasy (give me a “ballistic ascent” any day!). Continue reading “Is the Armadillo Vertical-Lift Spaceship a Viable Tourist Route?”
The European Space Agency’s Gravity field and state-steady Ocean Circulation Explorer (GOCE) should be in space by now. In fact it should have been launched back on September 10th, but it wasn’t to be. After the spacecraft (which has a striking resemblance to something a little more sci-fi… like a star destroyer) had been sealed into the payload bay of the Rockot launch vehicle at Plesetsk cosmodrome 800 km from Moscow, I assumed that was it, we wouldn’t be seeing GOCE ever again. But there was a glitch in the guidance and navigation subsystem of the Breeze KM third stage, thus postponing GOCE’s big day. GOCE was cracked open from its rocket powered cocoon to await a Rockot oil change.
