Our cycle of twittering (”HiTwycle“) is now over – the last image is on the ground, validated, processed, and will soon be released. (We release data in 100-orbit increments, which don’t necessarily fall along cycle boundaries, so the first half of cycle 89 will be released in May and the second half in June.)

It was fun to share some of the behind-the-scenes details with our followers! I thought it was pretty funny when Nick or I were too lazy to walk over to each others’ offices to ask a question, and asked each other over twitter instead. ha! I guess those questions probably give you a feel for the nitty-gritty of planning a cycle, anyway. I hope it was interesting! If you have any questions, feel free to ask them in the comments.

If you missed it and want to read through the saga, I made an archive of tweets with the #hitwycle hashtag. (I didn’t start this until part-way through, though, so unfortunately the first few days of tweets are missing. Soon you can check the Library of Congress for them! ) You can see the whole archive here:

Follow along! We’re in the midst of twittering an entire planning cycle, start to finish. Right now we’re in what’s called “IO week 1″, the second week of a 5-week planning process. You can follow the hashtag #hitwycle to see all the updates in real time.

This blog entry describes it in much more detail, from when we tried to do this last fall. Unfortunately, that time the spacecraft went into safe mode, and we had to stop the experiment. Here’s hoping for better luck this time! :\

Cast of characters:

One difference is that this time the CIPP (@nick_space) is here in Tucson. So it’s pretty easy to walk over to his office and ask him a question. Despite that, we’ve actually had a few discussions over twitter instead. Talk about lazy!! The good side of that is that you get to follow the day-to-day planning and see what it’s really like to plan two weeks of HiRISE images!

We are going to try to Twitter a planning cycle for the HiRISE (http://hirise.lpl.arizona.edu) experiment. The idea is to give people a feeling of all the work we have to do to get images from Mars out of a very special piece of equipment. Here are a couple of things you need to know to follow what is going on.

The scientist in charge of the scientific support for the cycle is called the CIPP. For cycle 75, that is @nick_space. Nick will be assisted by his Post-Doc., Anya, who is @mozhetbyt

The targeting specialist ensures that the plan produced can be implemented and keeps the CIPP from doing anything stupid. The targeting specialist is called the HiTS and for cycle 75 that is @laughingrid.

The HiRISE project has its own Twitter account (@HiRISE) which can also be followed.
We will try to use #hitwycle as a search hashtag for tweets.

If you live in Tucson, you might be interested to know that we’re looking for a new HiRISE Targeting Specialist (HiTS) here at HiROC!

Our faithful blog readers are probably already familiar with some of what the HiTS do, but for the rest of you, here are some past entries related to different aspects of the job:

• Welcome, Newbies! – Training other new HiTS
• ESP so far – In the extended mission, things are (supposedly!) easier…
• How big are our feet? – Planning software HiTS use, HiPlan
• High data rate and HiTemp – Some of the challenges of planning images
• Looking Back – Special sequence commanding

I’ve found it to be an exciting and rewarding job, but it’s not an easy one. You need to be the type of person who thrives under pressure; can deal with firm deadlines, but is also creative and self-motivated in between deadlines; pays attention to small details, but can also “see the big picture” (so to speak ). You need to be able to communicate with, and translate between, people with diverse backgrounds and experience, from researchers on the science team to NASA engineers. Ideally, you’d have some relevant scientific background (planetary science, astronomy, or geology, for example), be familiar with UNIX and some programming, and most importantly, be excited about exploring Mars!

Despite being several years into our mission, we’re still seeing fresh faces on the HiRISE team. Recently we’ve added some new hires: student validators, researchers, and Targeting Specialists (with whom I work the most). We also continue to involve new scientists in operations – Participating Scientists or post-docs who haven’t gone through the planning process before. They come to HiROC to train during their first cycle, so we have a conveyor belt of visiting scientists as well.

The first Monday in June when they all started was krazy – lots of new people wandering around, office chaos and computer confusion…. By now they’re settling in and things are cooling down somewhat, although at least for the Targeting Specialists, we consider it about a 6-month process to get fully up to speed. In the first few weeks, their eyes are usually glazed over with information overload. At this point, they probably feel like they’ve been dropped in the hot oil of confusion (it’s also 106F in Tucson, which doesn’t help), then dipped in sticky, overly detailed procedures. Sweet procedures….

While we go through this training, the new kids are keeping us veterans on our toes – I keep finding places where the procedures we told them to follow are unclear, there’s a hole in the middle where steps are missing, outdated, or just plain wrong! So it’s really a shared learning experience. Besides, it’s always good to have some fresh, hot ideas and different perspectives to keep us from getting jaded. or dangerously skinny.

I’m excited for them – the sugary thrill when their first commands execute on the spacecraft, the pride when their first beautiful images come down, the feeling of fullness and mastery when they finally become fluent in the foreign language of acronyms…. Other firsts I’m sure they’re not looking forward to are their first mistake, their first late night, their first bad image…. So not everything is warm with honeyed nostalgia.

I’m sure they’ll all do a wonderful job, though, and be valuable additions to the team. In the meantime, though, I could really use some donuts…. Welcome, newbies!

Mars is currently blanketed by a large dust storm. We first starting seeing it in late June. The MARCI instrument returns global daily mosaics of the planet, which we use like a weather report. These showed several dusty areas, and we had some hopes they would remain merely “regional.” However, in the following days, the storm activity increased, and winds blew the dust around the planet. Most of our images started coming back clouded over with dust. Some are just hazy, and some are completely obscured. Our Principal Investigator, Alfred McEwen, recently pointed out that this dust storm currently active in the Saharan desert on Earth looks very familiar!

At this point, the storm is considered a “hemispherical event,” meaning it’s mainly affecting “only” half of the planet (the southern hemisphere, in this case). We have our fingers crossed that this will not expand and become a global event like the 2001 dust storm.

It seems that things are (dare I say?) settling down into a routine here at HiROC. As the cycles progress, we get a little better with each one: software tools are being developed, our procedures are being refined, and we’re becoming more adept and making fewer mistakes (hopefully!). Of course, there are always little interruptions and semi-emergencies that preclude relaxing too much.

Tomorrow marks the beginning of the third two-week cycle in the primary mission. However, it’s only my first cycle! One Targeting Specialist is assigned to each cycle, and I’m on for cycle 3. Because we spend almost four weeks planning before the cycle even starts, there are three Targeting Specialists overlapping at any one time, in various stages of the planning process. Plus there’s a backup — HiBUTS, which stands for HiRISE BackUp Targeting Specialist. (I can’t take credit for that — that’s one of HiKu’s!)

Since before PSP started, we’ve all been working long hours. We haven’t had much time to blog, but right now I’m just waiting nervously for my commands to be radiated, so I thought I’d share this recipe. For all you faithful blog readers out there (all 2 of you? ), here’s my secret to surviving long workdays and cold nights:

A few of us were at HiROC Saturday, getting our parts of the operations process in order for the upcoming start of primary science (PSP).

That’s GuyMac on the left, HiCommander (me!) in the middle, and HiKu on the right.

Sorry we haven’t been posting much lately!

To tell the truth, some of us are experiencing a little bit of a lull. We’re in conjunction right now — this means that the Sun is directly between Earth and Mars, so we can’t communicate with the spacecraft. (Here’s a link with a few diagrams to illustrate this.)

The HiRISE instrument is turned off, and we’re not taking any images. However, there are other activities going on at HiROC….

We start imaging again on November 8, and a few of us are already planning for that. PSP, the Primary Science Phase, is divided into two-week cycles. The first cycle is rm001, the second rm002, etc. Each cycle has a Targeting Specialist assigned to it (this one isn’t me, or I wouldn’t have time to write this!). The Targeting Specialist works with a member of the science team, the “Co-Investigator of the Pay Period,” (”pay period” because of the two-week cycle) or CIPP. The CIPP helps to choose scientifically important targets, and the Targeting Specialist does the scheduling and commanding. They work together on coordinating with other teams, choosing camera parameters, etc. There are a lot of details that need to be worked out!
