Phoenix is Alive! Just in Time for Halloween

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…

Has Phoenix… Died?

Could this be the end of Phoenix? (NASA/JPL)
The end of the line? (NASA/JPL)

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…

High Resolution Earth Rise Video by Kaguya (SELENE)

A little bit of beautiful - the Earth rises over the lunar horizon (JAXA)

Using its High Definition Television (HDTV) camera, the Japanese lunar probe Kaguya captured an astounding video of the Earth slowly rising above the lunar horizon. The video was actually released at the start of this month, but it has only just come to my attention. The video was recorded on September 30th, as the probe orbited 100 km above the Moon. Stunning.

The Pessimism About Modern Space Flight

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’.

The New Horizons Pluto mission has just passed its 1000th day on the epic journey to Pluto, Charon and the Kuiper Belt. The Cassini probe is still doing its mission orbiting Saturn (since 1997). Oh, and the European Venus Express doing its quiet cruise around Earth’s evil twin planet.

The International Space Station is still going strong, proving on every day that passes that humans can live in space (no matter how difficult it is, we can do it, months at a time — but we need to work harder at zero-G plumbing!). Other nations are pushing into space too; China carried out its first spacewalk in September, India blasted its first lunar mission into space last week and the Japanese lunar orbiter just broke the bad news that there ain’t no ice in them thar craters

…lest not forget the robust Russian Soyuz space vehicle, having just reached its 100th flight!

The Universe Today is Unbanned from Digg.com!

Does Digg love the Universe Today again?
Does Digg love the Universe Today again?

Great news! It would appear that after only day one of the campaign to have the Universe Today un-banned from Digg.com, somebody in the admin staff was obviously paying attention (unless they are an avid reader of the Universe Today website too), and realised their mistake. Digg.com is now allowing articles from the Universe Today to be re-listed and dugg!.

I’d like to think that this was all down to blogging power — after all, this little space blogger was blamed for the whole NASA-Phoenix-Perchlorate saga! — but I’m just really happy that the guys at Digg have redeemed themselves a little.

This whole episode does however highlight an ongoing problem with banned sites, I hope it will help to refine Digg’s policy in the future.

Have a look at the first article to be Dugg after a long absence: “More Ares I Development Problems: Is it Really That Bad?” (one of mine!)

Universe Today Banned from Digg.com

Universe Today has been banned from Digg
Universe Today? Banned??

The Universe Today website has been banned from the social bookmarking site Digg.com. This might come as a surprise to many as the Universe Today is a great source of space, astronomy, science and educational news. Why would such a great resource be banned from a site that is based on community participation?

UT has been captained for many years by its founder and publisher Fraser Cain – I remember first signing up to the UT newsletter in 2001 – and the whole aim of the site is to reach out to Internet users, distributing the best space-based news a website can bring. Surely this is the type of site Digg would want to be promoting? Apparently not.

Digg Effect Destroys Astroengine (But Healing Now)

Wow, what a stressful day! On writing One-Way Mission to Mars: Top 5 Items to Pack last night, I had no idea about the consequences. This morning the article exploded onto the front page of Digg.com, sending a flood of traffic into Astroengine.com. Although my bandwidth is more than capable of dealing with the situation, the server was quite literally paralysed, causing the technicians at GoDaddy.com to pull the plug (can’t blame them, apparently all the other sites on the shared server were knocked out).

I’ll post a more detailed post soon, but should anyone want to know the best course of action when dealing with an uncontrollable flood of traffic, here’s what I had to do:

The first measure was to stem the flow of traffic from the referrer causing the server outage. Once the relentless barrage of Digg users were blocked, the GoDaddy admin staff were reassured the problem wouldn’t reoccur if they put Astroengine.com back online. The second measure is a longer-term solution until I migrate the site to a better server. WP Super Cache creates html versions of Astroengine’s php pages, thus bypassing the execution of php scripts every time someone visits the site (vastly reducing the load on the server).

Thanks to Fraser (my publisher at Universe Today) for helping me out and giving these tips when dealing with a Digg explosion.

So, now I am going shopping. It’s fantastic to have these bursts of visitors, but the time is coming when I’ll need to upgrade. I’m either going to go the route of buying virtual-dedicated or a dedicated server. Any suggestions for which hosting providers have the best service/price? I’m most likely going to stay with GoDaddy, but I’m open to suggestions.

Apologies for dropping offline today, hopefully this will be the last interruption to service!

Cheers, Ian

One-Way Mission to Mars: Top 5 Items to Pack

Imagine: You have been selected as one of the first six people to go to Mars and your sole mission is to set up a manned outpost on the Red Planet. Forget the science, forget the long-term goal to spread humanity amongst the planets, your one and only task is to survive. If you live long enough to put your boot print in the Martian regolith, or long enough to eat your first meal, sleep to see your second sol or celebrate your proto-colony’s first home cooked meal, it’s a bonus. You have to survive long enough to give mankind a foothold to begin living on Mars.

Assuming you and your five crew have set up camp. You’ve landed next to all the basic supplies you’ll need for the next few years, plus the equipment to build a sustainable settlement. The pressure of making it through the first day is off. You have a routine, and everyone appears to be doing well. How will you fill your time? No doubt simply living will fill all your waking hours, but humans being humans, you’ll want to make your experience unique, you’ll want to have some fun. Whether it’s taking some time to think about Earth and your family, or it’s taking a hike up the nearest mesa to claim the early Mars World Record of “climbing the highest, ever.”

If you could take 5 things to Mars with you (ignoring the essentials like water, food, toothbrush, socks, iPod), what would they be? Assuming cost and weight isn’t an obstacle (I’ll be a billionaire and I’ve chartered a SpaceX Falcon 9 Heavy just to transport “personal items”) here’s my top five luxury items I’d take to Mars with me…

Star Trek Inspired: Space Shuttle Enterprise

Space Shuttle Enterprise was the first ever shuttle to be constructed. It never made it into space, it was used purely for atmospheric test flights, but Enterprise was a significant craft. Originally NASA planned to designate the shuttle Constitution, but after a a sustained write-in campaign, NASA changed its name in honour of the Starship Enterprise from the original series of Star Trek. In 1976, the USS Enterprise (NCC-1701) was being captained by Captain Kirk (played by William Shatner), and some of the original series actors were at the roll-out ceremony in Palmdale manufacturing facility in California.

A wonderful scene capturing the beginning of 32 years of shuttle operations. This is an especially poignant image as Star Trek creator Gene Rodenberry and two of the original Star Trek cast, DeForest Kelley and James Doohan have since passed away.
