Q: Where can I find information about the BARREL Project?
A:There are a few different BARREL Websites which all have some great information.
1) Main Project Website
project information and links to all the pages listed below
2) BARREL Blog (You are already here!)
http://relativisticballoons.blogspot.com (or our science blog barrelscience.blogspot.com)
Best place to go for current news. We'll be posting information about upcoming launches, launch times, interesting observations, ect.
3) Archival Data Access
Q: What Height do the balloons fly at?
A: ~30 km or ~ 18.6 miles high. This isn't a constant altitude of the balloons, but our estimated range is between 30 - 35 km. For reference, the guy who jumped from "space: and broke the sound barrier, Felix Baumgartner, he jumped from 39 km. He could have hit one of our balloons!
Q: What time zone are SANAE IV and Halley 6 in?
A: Although the stats ions are in different time zones, they are both using GMT (or UT = Universal time. )
Q: What time zone is Kiruna Sweden in?
A: Central European Time Zone UT + 1 hour)
Q: When did the 2015 campaign start?
A: We are currently in Sweden waiting for a chance to launch our first balloon.
Q: How long will the 2015 campaign last?
A: We don't know. This campaign will be shorter then the last two as it's during a time called turn around instead of during the circumpolar winds. This is when the circumpolar winds change direction, allowing us to launch a balloon and have it stay in relatively the same spot. However this will last at most around two weeks.
Q: How many balloons are you launching in the third campaign?
A: We will launch 6 payloads. They will be called 3A, 3B, 3C, 3D, 3E, 3F
Times of launch and termination To be determined...
A: We were able to launch our first payload on December 27th 2013, about a half a week earlier than last years campaign.
Q: How long will the 2014 campaign last?
A: We don't know, probably close to the middle or end of February. Depending on the weather we may be able to launch our last balloon by the beginning of February. However once we launch the last balloon, the campaign isn't finished. The balloons can stay up for a week or two after they've been launched (look at 1I from the first campaign, it had the longest duration, 38 days!) Of course the work doesn't end here either. We have to analyze all the data, write up the papers, present our findings, and collaborate with others; Oh and of course we still have to decide if we'll have a plan a third campaign.
Q: How many balloons are you launching in the second campaign?
A: We plan to launch 20 balloons; 10 from SANAE IV and 10 from Halley 6. Easch payload name starts with 2 (for the second campaign) and is followed by a letter. These letters were given to the payload as they were started to be built. Those in blue have been launched, those in red have been cut down, and those in black have yet to be launched.
Payloads at Halley 6:
2I, 2K, 2L, 2M, 2N, 2O, 2P, 2Q, 2R, 2T
Payloads at SANAE IV:
2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2J, 2X, 2W, 2Y
There are also spares at each location (not listed here until they have launched). These are extras. We may use them for parts, we may use a full payload in case one crashes before we get any real amount of data. We may also use them for a third campaign.
Times of launch and termination
2C - Launched on Jan 20th at 18:16 UT. We lost contact with 2C on Jan 25th. It should have self terminated by Jan 27th.
2O - Launched on Jan 26th at 17:40 UT.
2D - Launched on Jan 27th at 15:52 UT. 2D was terminated on Jan 29th at 03:31 UT. It was a slow leaker but still saw some of the flares occurring over the last day.
2P - Launched on Jan 30th at 11:25 UT.
2E - Launched on Jan 30th at 16:00 UT.
2F - Launched on Feb. 1st at 16:11 UT.
2Q - Launched on Feb. 2nd.
